Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Goes well beyond the annotations by disclosing a non-obvious credential model: the token comes from the server's FORGEJO_MIRROR_TOKEN env var and must never be passed as an argument. It also explains the use_ssh branch and that the response then carries a `public_key` to install on the remote — exactly the kind of side-effect/auth detail annotations cannot convey.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Three sentences, front-loaded with the purpose, then prerequisites and credential handling. No filler; the parenthetical example ('e.g. a GitHub mirror') makes the intent concrete in a few words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

There is no output schema, and the description covers the notable return case (public_key when use_ssh=true) plus the write-mode requirement, which is sufficient to call it correctly. It omits failure behavior and whether the mirror syncs immediately on creation, a minor gap for a mutating tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3; the description still adds value by clarifying that no credential parameter exists (env-var sourced) and by framing use_ssh as the key-auth path, discouraging an agent from inventing a token argument. It adds no detail on interval, branch_filter, or sync_on_commit beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Add a push mirror') and explains the mechanism concretely: Forgejo/Codeberg auto-pushes this repo to an external remote without a local `git push`. This clearly separates it from siblings like delete_push_mirror, list_push_mirrors, and sync_push_mirrors.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly gives the precondition 'Requires write mode' and names the SSH alternative ('or set use_ssh=true for key auth'), which is actionable guidance. It does not explicitly contrast with sync_push_mirrors (manual trigger vs. scheduled) or state when-not-to-use, so it falls short of the top band.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Goes well beyond the annotations: it discloses that the response is the run in list_workflow_runs' shape, that the outcome must be read from `status`, and that Forgejo silently accepts an already-finished run unchanged while Gitea may refuse it. That platform-divergent semantics is exactly the context annotations cannot convey, and it is consistent with idempotentHint=true and destructiveHint=true.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Three sentences, front-loaded with the action and its prerequisites, then the return contract, then the platform-specific edge case. No filler; each clause carries information an agent would otherwise have to discover by trial.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

No output schema exists, and the description compensates fully by describing the return value's shape, the field to inspect, and how that field behaves differently across Forgejo and Gitea. Nothing needed to invoke or interpret the result is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% and each parameter is documented in the schema, so the baseline is 3. The description's 'owner/repo/run_id' mention merely restates the parameters without adding format or constraint detail beyond what the schema already says.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

Specific verb plus resource plus scope: 'Cancel a pending or running Actions workflow run'. This clearly separates it from get_workflow_run (read), rerun_workflow (re-execute), and dispatch_workflow (start), so an agent can choose it without opening the schemas.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives real preconditions — 'requires write mode', 'on Forgejo 16+ or Gitea', and restricts the target to 'pending or running' runs. It does not explicitly name sibling alternatives or say when not to use it, so it falls just short of a 5.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare the safety profile, yet the description adds substantive context: it posts as the write token's account, requires write mode, is public on a public repo, notifies @mentions and all watchers, and is non-idempotent so a duplicate call posts twice. That is exactly the side-effect information an agent needs before a write.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with the action, then side effects, then the retry caveat, then sibling routing — each sentence carries distinct, actionable information with no filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

No output schema exists, and the description compensates by naming the return shape (new comment in list_issue_comments' shape with id, user, body, created_at, url). Combined with auth mode, side effects, and alternatives, nothing needed to invoke it correctly is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3, but the description goes beyond it by clarifying that index is the shared issue/PR number and that body is Markdown with public visibility and mention semantics. Owner/repo are left to the schema, which is fine given full coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

Specific verb plus resource ("post a comment on an issue or pull request") with the added detail that issues and PRs share one numbering, which resolves a real ambiguity. It is clearly distinguished from edit_issue and create_pull_request_review later in the text.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly routes the agent elsewhere: edit_issue for close/reopen/relabel and create_pull_request_review for a verdict-bearing review. It also gives a retry procedure (check list_issue_comments before retrying) that directly follows from the non-idempotent behavior.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=false, destructiveHint=false, idempotentHint=false and openWorldHint=true. The description adds the write-mode authorization requirement and states the return payload (name, head commit, protection), which the annotations do not cover — real added value for a mutation tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Two compact sentences, front-loaded with the action and its argument layout, then the return shape. No filler and nothing an agent must read twice.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a low-complexity create tool with no output schema, the description covers the action, the required write-mode precondition, and the shape of the result by reference to list_branches. Nothing needed to invoke it correctly is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so all four parameters are already documented in the schema, including old_ref's default-to-default-branch behavior. The description only restates the ordering (owner/repo/new_branch, optional old_ref) without adding format or constraint detail, so the baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb+resource ('Create a branch in a repository') and pins the call shape (owner/repo/new_branch, optional old_ref). It also names the sibling whose return shape it mirrors (list_branches), so an agent can tell it apart from delete_branch/list_branches without opening a schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives the key precondition ('requires write mode'), which is the main gating decision for this tool, and implicitly routes the agent to write-mode enablement. It stops short of naming enable_write_mode/write_status explicitly or saying when not to use it, so it is clear context rather than a full when/when-not guide.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=false, openWorldHint=true, and idempotentHint=false, so the safety profile is covered. The description adds meaning the annotations cannot: write-mode must be enabled first, and the returned object matches get_issue's shape with a `number` usable as a stable handle thereafter — genuinely useful invocation context.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Two compact clauses with zero padding; the operation and its required inputs come first, and the return-shape note follows. Every sentence carries information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description usefully explains the return value and how to reference the created issue. The write-mode gate is disclosed. Only minor gaps remain, such as whether repository-level permissions or scopes are also needed.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% and every parameter is described in the schema, so the baseline is 3. The description confirms title is required and body is optional, but adds no syntax or domain meaning beyond what the schema already provides.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description gives a specific verb and resource ('Create an issue in a repository') and names the exact required inputs (owner/repo/title), which distinguishes it from the siblings edit_issue, comment_on_issue, and list_issues without needing to open the schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

It states a real precondition — 'requires write mode' — which tells the agent it must call enable_write_mode first, and it points at get_issue for the result shape. It does not explicitly contrast with edit_issue or comment_on_issue, but the create-vs-edit distinction is inferable from the sibling names.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description adds substantial context beyond the annotations: write-mode requirement, single-commit behavior, stale-sha refusal to avoid overwriting concurrent changes, branch versus new_branch commit behavior, and the return payload of new sha and commit.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The core operation and its create/update distinction are front-loaded, followed by the relevant safety and branch workflow details. The paragraph is dense but every sentence contributes to correct invocation.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given a mutation tool with no output schema, the description covers the important behavioral details, safety constraints, branch workflow, and return values. Nothing critical for an agent to call it correctly appears missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the schema already documents all parameters. The description still adds useful synthesis by explaining the sha create/update distinction, the whole-file UTF-8 content expectation, branch defaults, and the PR-oriented purpose of new_branch.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific action and resource: create a file or replace its content as a single commit. It clearly distinguishes the create-vs-update behavior via the sha parameter and names get_file_contents as the source for that sha.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

It explicitly explains when the tool creates versus updates, requires write mode, warns that missing sha creates and stale sha is refused, and describes branch/new_branch usage for direct commits or pull request preparation. The alternative source for sha is named.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=false, idempotentHint=false and openWorldHint=true, so the mutation/non-idempotent profile is covered structurally. The description still adds real value by naming the write-mode auth prerequisite, the return shape, and the stable `number` handle — things annotations cannot express. It omits failure behavior (duplicate PRs, invalid head/base) which keeps it below a 5.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Two tight sentences: the action and its inputs first, then the return value and the identifier for follow-up calls. No filler, no restatement of the title.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description helpfully explains the return value by reference to get_pull_request's shape and highlights `number` as the handle for downstream tools. The write-mode requirement covers auth. Missing only error/precondition behavior for a 6-parameter, open-world mutation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the baseline is 3. The description merely enumerates the parameter names it already lists in the schema and notes body is optional, adding no syntax or format guidance beyond what the schema gives (e.g. the cross-repo `user:branch` convention in the schema is not echoed).

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

Uses a specific verb (open/create) plus resource (pull request) and immediately names the scoping entities (owner/repo) and parameters. An agent can distinguish it from list_pull_requests, get_pull_request, and merge_pull_request without inspecting the schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

States the key enabling condition 'requires write mode', which directly activates the enable_write_mode sibling, and implies creation-before-merge ordering. It stops short of explicit alternatives or exclusions (e.g. what to do if a PR already exists for head/base, or when to create_branch first).

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Goes beyond the annotations by disclosing the write-mode auth requirement, the self-approval restriction enforced by the forge, the default commit_id behavior (current head), and the return shape. Annotations already cover safety hints (readOnly=false, destructive=false, idempotent=false), so this added context is genuinely additive; failure modes and rate limits remain unstated.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loads the action and required identifiers, then layers in constraints and defaults in a single dense paragraph with no filler sentences. Each clause (verdict, body requirement, commit_id default, self-approval rule, return shape) earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a 6-parameter mutation with no output schema, the description covers prerequisites, parameter semantics, forge-imposed constraints, and even the return value shape. Nothing an agent needs to invoke it correctly is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the schema already documents every parameter including the verdict enum and commit_id default. The description restates these without adding syntax or format detail beyond what the schema provides, matching the baseline 3 when structured data carries the load.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ("Submit a review on a pull request") and immediately enumerates the required identity fields. The reference to list_pull_request_reviews' shape distinguishes it from the read-side sibling and from merge_pull_request, so an agent can route it without opening the schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly names the precondition "requires write mode" and encodes the verdict-selection logic (approve / request_changes / comment) plus the rule that body is mandatory for the latter two. It also warns that a forge won't let you approve your own PR. Missing is an explicit pointer to alternatives like merge_pull_request, so it falls just short of 5.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The annotations already declare readOnlyHint=false, destructiveHint=false, idempotentHint=false, and openWorldHint=true; the description adds value beyond them by stating the write-mode requirement, the tag-creation side effect of target_commitish, and that the returned release id addresses its assets. It could say more about non-idempotency (repeated calls with the same tag fail), but the added context is real.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Three sentences, front-loaded with the verb+resource, followed by prerequisites and the return value. Every sentence carries information an agent needs before calling.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a create tool with full schema coverage and no output schema, it covers the key call-time needs: write mode, tag existence, and the return shape with the id used for asset operations. Minor gaps (e.g., what happens on duplicate tag/release) remain but are not blocking.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so all eight parameters are already documented, including the tag_name/target_commitish interaction the description restates. The description adds no syntax, format, or default information beyond the schema, so baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource ('Create a release on a git tag') and its sentences distinguish it from get_release and edit_release in the sibling list. The core purpose is understandable without the schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

It clearly states the write-mode prerequisite and the precondition that the tag must exist unless target_commitish is supplied, which is actionable guidance. It does not explicitly name enable_write_mode or edit_release as alternatives, leaving the agent to infer the sibling to call first.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Goes well beyond the annotations: discloses the write-mode requirement, the private-by-default behavior, that the repo starts with no commit or branch, and the concrete failure mode (fails on duplicate name). The non-idempotency is also restated in operational terms rather than just as a hint flag.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with the primary action and its scope constraint, and every clause carries real information. It is a single dense sentence chain with semicolons, which costs a little readability but wastes no words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description supplies the return shape (get_repo's shape) and the post-creation state (empty repo, no branch). Combined with prerequisites and failure behavior, an agent has everything needed to call it correctly and handle the result.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, and the schema already documents name, private (with default), and description. The description only echoes the private-by-default semantics, so it adds little beyond the structured fields — baseline 3.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb+resource (create a repository) plus the key scope constraint: under your own account, not an organization. It separates itself from create_or_update_file, migrate_repo and edit_repo by name, so an agent can route correctly without opening a schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives explicit when-to-use (push a first commit or add a first file), when-not-to-use (organizations; copying an existing repo with issues/PRs -> migrate_repo; changing settings later -> edit_repo), and the write-mode prerequisite. Nothing is left to inference.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare destructiveHint=true and idempotentHint=true, but the description goes further: it names server-side refusal rules (default/protected branches) and the real consequence (commits only that branch held become unreachable). That is exactly the irreversible-effect context annotations cannot express.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Three short sentences, front-loaded with verb and resource, then constraints, then the data-loss warning with its mitigation. No filler and no repetition of the annotations.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

A destructive mutation with no output schema needs prerequisites, refusal behavior, and consequence disclosure, and all three are present. Nothing an agent needs to call it safely is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% and each parameter is already documented, including the `feature/login` example for branch. The description's '(owner/repo/branch)' restates the required trio but adds no syntax or constraint detail beyond the schema, so the baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Delete a branch') and immediately scopes it to owner/repo/branch. An agent can distinguish it from create_branch and delete_repo without opening any schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives an explicit prerequisite ('requires write mode'), explicit exclusions (the forge refuses default and protected branches), and a pre-condition cross-reference (check `merged` via get_pull_request). This is when-to-use, when-not-to-use, and the alternative in three clauses.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already flag destructiveHint and idempotentHint, but the description adds real context beyond them: the write-mode auth requirement, the stale-SHA refusal behaviour, and the commit target semantics (branch vs. new_branch created from it). It omits only failure/error surface details.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with the action and required addressing, then prerequisites, then branch behaviour. Dense and largely waste-free, though the parenthetical key list and the punting of `message` to forge defaults make the second sentence a little packed.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a destructive mutation with no output schema, the description covers auth prerequisites, staleness safety, branch targeting, and states that the response is the commit. Nothing critical to correct invocation is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is a 3, and the description earns above that by explaining provenance ('sha is the file's current blob SHA from get_file_contents') and the relationship between branch and new_branch that the schema only states in isolation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a specific verb+resource ('Delete a file as a single commit') and immediately names the four-part addressing scheme (owner/repo/path/sha). It is clearly distinguishable from sibling mutations like delete_branch or delete_repo.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

It states the prerequisite ('requires write mode') and where the sha must come from ('get_file_contents'), with the consequence of a stale value. It does not explicitly contrast with create_or_update_file for content removal, so it stops just short of full alternative routing.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already mark this as destructive, idempotent, and not read-only, but the description adds crucial scope: only the mirror configuration is removed, syncing stops, and the remote repository and already-pushed content remain untouched. It also specifies the response shape {deleted: remote_name}, which the annotations do not cover.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is compact and front-loaded, moving from operation to scope to return value to alternative behavior. Every sentence adds actionable information, and none is redundant padding.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a destructive tool with no output schema, the description supplies the missing context an agent needs: write-mode requirement, exact deletion scope, return shape, and the no-edit-tool workaround using add_push_mirror. Nothing essential is omitted.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents owner, repo, and remote_name. The description reinforces that remote_name must come from list_push_mirrors, but it does not add syntax or format details beyond the schema, so the baseline of 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource: removing one push mirror from a repository by remote_name. It distinguishes this from list_push_mirrors and add_push_mirror, so an agent can identify the correct operation without reading the schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

It states the prerequisite (write mode) and explains the alternative path when the goal is merely to stop automatic syncing: there is no edit tool, so delete and re-add via add_push_mirror. That gives explicit when-to-use and when-not-to-use guidance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare destructive=true, idempotent=true, readOnly=false, and openWorld=true. The description adds useful context beyond those hints: write mode is required, and deleting an old same-named asset prevents Forgejo from retaining duplicates.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two focused sentences with the action front-loaded and the prerequisite/use case following immediately. There is no redundant restatement of the title or schema.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple destructive delete with full schema coverage and rich annotations, the description supplies the remaining practical context: write mode and the replacement workflow it supports. No output schema is needed for a deletion operation of this kind.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so all four parameters are already documented. The description reinforces attachment_id as the identifying parameter but adds no syntax, format, or constraint details beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource: deleting one release asset identified by attachment_id. It is clearly distinguishable from sibling tools such as delete_repo, delete_file, upload_release_asset, and list_release_assets.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives a concrete usage condition: replacing a same-named asset that Forgejo would otherwise keep alongside the new one. It also states the write-mode prerequisite, though it does not explicitly name alternative tools or state when not to use it.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare destructiveHint and idempotentHint, but the description adds genuinely new context: no undo, write mode required, admin-scoped write token, and that a confirm mismatch is refused *before anything is sent* — a pre-flight safety guarantee not present in the structured fields. The return shape is stated explicitly since no output schema exists.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Four dense sentences, zero waste, and the irreversible nature plus confirmation requirement are front-loaded before the alternative and return value. Each sentence carries distinct operational value.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

A destructive, irreversible mutation with no output schema — exactly where descriptions must do the most work. Irreversibility, auth requirements, the safety guard, the failure mode, and the response shape are all covered, so an agent can call it correctly without guessing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3; the description goes further by explaining the confirm guard's runtime behavior ('a mismatch is refused before anything is sent'), which the schema only states as a requirement. Still, owner/repo semantics gain little beyond their schema entries.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

Opens with a specific verb and resource ('Permanently delete a repository') and enumerates the scope of destruction (issues, PRs, releases, wiki, settings), which immediately separates it from non-destructive siblings like edit_repo or delete_branch.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly names the alternative and the condition selecting it: 'To retire a repo but keep it readable, archive it with edit_repo (archived=true) instead.' It also states a pre-call prerequisite (user confirms the exact repo) rather than leaving it to inference.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations declare idempotentHint=true and destructiveHint=false, but the description adds critical context beyond them: the tool toggles a gate that causes write tools to be refused, is safe to call redundantly, and returns the instance plus write_mode_active=false. It also instructs the agent to relay the result to the user, which annotations cannot convey. Lacks any note on permissions or edge cases, so not a 5.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Three short sentences, front-loaded with the action and its consequence, followed by safety note and response shape. Every sentence carries distinct information with no redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

No output schema exists, and the description compensates by describing the response ('the instance and write_mode_active=false'). Together with the timing guidance and safety note, an agent has everything needed to call it and report back correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool takes zero parameters, so there is nothing for the description to disambiguate; baseline for 0 params is 4. The schema is empty and fully consistent with the no-argument invocation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb+resource ('Leave write mode now') and immediately explains the effect: write tools are refused until enable_write_mode. It distinguishes itself clearly from the enable_write_mode sibling by naming it and describing the opposite transition.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives explicit timing guidance ('Call it as soon as a batch of writes is done') and the alternative wait path ('instead of waiting for it to time out'). Also states it is harmless when write mode is already off, removing a common hesitation for the agent.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Adds real information beyond the annotations: an auth/permission requirement (write mode), a precondition on the workflow file itself, and divergent return behavior per host (Forgejo returns the created run, Gitea returns only an acknowledgement). Annotations only cover write/idempotency hints, which this description supplements rather than repeats.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Dense but front-loaded: trigger, addressing, precondition, discovery path, then return behavior. A few clauses duplicate the schema's `workflow` description, which is minor waste but not padding.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description correctly fills the gap by explaining what each host returns and how to locate the run afterwards via list_workflow_runs. Nothing an agent needs to invoke this correctly is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so every parameter is already documented. The description's note that `workflow` is a file name and where to find it largely restates the schema's own text, adding little beyond the baseline.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Trigger an Actions workflow via workflow_dispatch') plus the exact addressing tuple (owner/repo/workflow/ref). Clearly separates it from siblings like rerun_workflow by tying it to a fresh workflow_dispatch trigger rather than an existing run.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives concrete preconditions ('requires write mode', 'must declare an on: workflow_dispatch trigger') and routes the agent to get_file_contents when the workflow name is unknown. It stops short of explicitly contrasting with rerun_workflow or cancel_workflow_run, which the sibling list makes relevant.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations declare destructiveHint/idempotentHint but the description adds the real behavioral substance: partial-update semantics ('only the fields you pass change'), the replace-vs-merge distinction per field, exact-name label matching with a labels_not_found reporting channel instead of silent drops, and removal conventions (milestone 0, empty due_date). This is exactly the context annotations cannot convey.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

A single dense paragraph front-loaded with target, identifiers and precondition, then field semantics, then edge behaviors. Nearly every clause carries unique information, though the run-on structure of the field list is slightly harder to scan than a short bulleted framing would be.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Ten parameters, no output schema, and yet covered: it names the return shape ('answers with the issue in get_issue's shape'), the partial-update contract, the write-mode prerequisite, and the PR-number edge case. An agent can call this correctly without further discovery.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so replacement semantics, the milestone 0 convention and the empty-due_date convention are already documented in the schema. The description mostly restates them; its only genuinely new element is the labels_not_found side channel, so the baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

Opens with a specific verb+resource+scope ('Edit an issue in place (owner/repo/index; requires write mode)') and enumerates exactly which fields it can mutate. Clearly distinguished from read-side siblings like get_issue and list_issues and from create_issue.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

States the write-mode precondition and clarifies the non-obvious routing case: the same call works on a pull request number, so state=closed closes a PR without merging (versus merge_pull_request). It gives good positive selection context but names no explicit 'use X instead' alternative for comments or other mutations.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare destructiveHint=true and idempotentHint=true; the description adds real value on top by disclosing write-mode gating, partial-update semantics ('only the fields you pass are sent'), and the asset-preservation consequence of editing rather than recreating. It does not describe the response payload, but it is consistent with every annotation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Three sentences, all front-loaded: action and identifier first, then field semantics, then the decision guidance. No hedging or filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description notes parity of endpoint and response across Forgejo and Gitea, and write-mode gating is covered. Nine parameters with three required are adequately framed, though the shape of the returned release is only alluded to via 'same endpoint and response'.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so every parameter including owner, repo, and release_id is already documented. The description restates the field list and adds only the optional-field semantics, which the schema's nullable defaults already imply.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Edit an existing release in place, by release_id') and enumerates the mutable fields, which separates it cleanly from create_release, get_release, and upload_release_asset in the sibling list.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives a concrete use case ('correct published release notes') plus the rationale for preferring it over delete-and-recreate, which loses assets. It also states the 'requires write mode' prerequisite, though it never names create_release as the path for new releases, so the exclusion is only implicit.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare the mutation profile (destructive, idempotent, write-required). The description adds valuable behavior beyond annotations: partial update semantics, no rename support, and the non-obvious 404 behavior when unit toggles are off. It does not cover reversibility or permission nuances, but with annotations carrying that weight, this is strong.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is front-loaded with the action and editable fields, then adds only high-value caveats: partial updates, no renames, 404 behavior, and write mode. Every sentence earns its place despite the density required for 14 parameters.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a destructive, write-required, 14-parameter tool with no output schema, the description covers the essential context: which fields are editable, that updates are partial, that renames are unsupported, the 404 quirk for disabled units, and the write-mode prerequisite. Nothing critical is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents every parameter, including the 404 behavior for has_releases and has_actions. The description groups and summarizes the fields but adds little semantic detail beyond what the schema provides; baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('Edit') and resource ('repository settings') and enumerates the editable fields, clearly distinguishing it from read-only siblings like get_repo and creation tools like create_repo.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives clear operational context: only provided fields change, renames are unsupported, and write mode is required. It also explains the 404 symptom for disabled units, which helps an agent decide when to call this tool. It does not explicitly name alternative sibling tools, but the usage conditions are well covered.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Adds substantial behavior beyond annotations: time-limited mode, default and maximum duration, prerequisite for writes, user-announcement requirement, and the need to name the instance from the returned field when multiple servers/forges are configured. These are operational details an agent needs and they do not contradict the annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loads the core action and prerequisite, then adds the user-facing announcement requirement. It is compact with no wasted text.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Covers prerequisite, duration behavior, and an important output-related instruction about the returned instance field. Given the simple one-parameter schema and informative annotations, no essential calling context is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The single optional minutes parameter has 100% schema description coverage, including default, cap, and timer behavior. The tool description repeats default 10 and max 60 but adds no meaningful parameter semantics beyond the schema, so baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ("Enter write mode") and scopes it with duration limits. It is clearly distinct from sibling write tools and from disable_write_mode.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly says the tool is "required before any write tool," giving clear usage context. It does not explicitly name disable_write_mode as the way to exit early or state when not to use it, so it falls short of full alternatives/exclusions guidance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Beyond the readOnlyHint/openWorldHint annotations, it discloses two non-obvious behaviors: state is omitted entirely when the instance reports nothing for the ref (a real edge case), and target_url is returned relative to the instance origin so the host must be prefixed before following. Neither fact is derivable from annotations or schema.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with the purpose and the routing decision in the first two sentences, with the edge-case and URL caveats after. Dense but every sentence carries information; the only mild cost is a packed third sentence combining two distinct caveats.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description does real work by naming the possible state values, noting the per-check latest-state detail, and covering the omitted-state and relative-URL cases. It stops short of describing the remainder of the response envelope (e.g. the checks collection and its fields), which is the main residual gap.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so baseline is 3; the description adds a little by framing ref as 'the commit, branch or tag to judge' and showing the composite (owner/repo/ref) addressing form. Most semantic weight still sits in the schema, so it is only a modest lift above baseline.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('rolled-up CI verdict for a commit, branch or tag') and enumerates the exact output states (success, pending, failure, error, warning). It explicitly distinguishes itself from the sibling get_commit_statuses, so an agent can choose without opening either schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives an explicit decision rule: 'This is the tool for "did CI pass?"', then says the sibling returns transition history which is 'the wrong shape for that question.' Both the when and the when-not are stated with a named alternative.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations only declare readOnly and openWorld, so the description must carry the return-shape burden and largely does: it enumerates the signature states, names `signer` and `reason`, and flags a real caveat that gpg.error.no_gpg_keys_found is ambiguous. It stops short of stating error behavior for a missing sha or the rest of the returned fields.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with the verb, resource, and keying triple, then the use case, then the caveat — a sensible ordering with no filler. The final sentence is long and dense but each clause carries distinct information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a read-only fetch with no output schema, the description covers the field set by reference ('slimmed to the same fields as list_commits') plus the signature-specific fields an agent most needs. Slight gap in not covering not-found behavior or fields unique to this view.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% and the schema already explains that a branch or tag name resolves as well as a full id. The description only restates the owner/repo/sha triple, adding no meaning beyond the schema, so the baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Get one commit') with the keying triple (owner/repo/sha) and a scoping note that ties it to list_commits. That contrast is enough for an agent to distinguish it from list_commits and the status-oriented siblings.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly names the primary use case ('use it to check whether a commit was signed and whether the forge could verify it'), which is real routing guidance. It lacks explicit when-not/alternative phrasing (e.g., versus get_commit_statuses or list_commits for bulk), so it falls short of a 5.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations only cover read-only/open-world; the description adds substantially beyond them: results are append-style history rather than current state, the newest entry per context is the verdict, target_url is origin-relative and must be prefixed, and creator/timestamps are dropped. That is exactly the context annotations can't carry.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with the action, then the return shape, then the alternative-tool routing, then caveats. Every sentence carries operational information — even the closing note about dropped fields prevents a wrong expectation about the payload.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description still enumerates the returned fields, explains the history-not-state semantics that would otherwise cause misinterpretation, and warns about the relative target_url. An agent can call and interpret this correctly without further context.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so baseline is 3. The description elaborates on `ref` (commit, branch or tag) and the owner/repo/ref path shape, but `page` and `limit` are left entirely to the schema, so no value is added beyond structured data.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb plus resource ('List the statuses reported against a commit, branch or tag') and immediately names the fields returned per entry. It explicitly distinguishes itself from get_combined_status, a sibling that would otherwise look interchangeable.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives an explicit routing rule with the exact question it answers — 'for "did CI pass?" call get_combined_status instead' — and explains why (per-check history vs one latest state). It also tells the agent when this tool is the only route to detail (no logs API; follow target_url).

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With readOnlyHint/openWorldHint already covering safety, the description adds real behavioral detail: content is decoded as text, ranges are clamped to the file, and total_lines is always returned. It doesn't cover binary/large-file failure modes or authorization errors, so it is not exhaustive.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

One dense but front-loaded sentence-plus-clause with no filler; the paging hint is the last thing an agent needs and arrives last. Slightly compressed — the 'decodes text, lists directories' clause is terse enough to need a second read.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description still conveys the shape of the return (decoded text plus total_lines) and how to page it. Missing only peripheral detail such as error or non-text file handling.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so baseline is 3; the description goes further by explaining the clamping behavior and the inclusive 1-indexed window rationale, which the schema doesn't state. It says nothing extra about ref/owner/repo beyond what the schema already documents.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb+resource ('Read a file's contents from a repository') with the identifier triple spelled out, plus two meaningful behaviors (text decoding, directory listing). An agent can distinguish it from get_repo_tree or get_commit without opening the schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives a clear operating context: use a start_line/end_line window to page a large file 'instead of pulling it whole,' and notes it lists directories. It stops short of naming explicit alternatives (e.g., get_repo_tree for recursive listings) or exclusions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already cover the safety profile (readOnlyHint, openWorldHint), and the description adds genuine behavioral detail beyond them: PR numbers are accepted here and flagged via `pull_request: true`. It doesn't cover failure modes (e.g., 404 for a nonexistent index) or pagination/auth, so a 4 rather than 5.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

A single front-loaded sentence carries purpose, addressing, field delta, and the PR-number caveat with no filler. The em-dash aside makes it dense on first read but every clause earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

There is no output schema, so the description must characterize the return value — it does so by describing fields relative to list_issues plus body, locked, due_date and ref, which is enough for an agent to know what it gets. Error and empty-result behavior are the only meaningful omissions.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, with each of the three parameters documented inline, so the baseline is 3. The description's '(owner/repo/index)' notation restates the composite key but adds no format or constraint detail beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource — 'Get one issue by number from a repository' — and defines the addressing triple (owner/repo/index). It also distinguishes itself from both list_issues (whose fields it extends) and get_pull_request, so an agent can pick it without opening a schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explains the shared issue/PR numbering and that a PR number is valid here, plus that get_pull_request is the place for branches and merge state — which effectively routes the agent. It stops short of an explicit 'use list_issues to browse, use this to fetch one' statement, so not a full 5.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations only cover read-only and open-world; the description adds substantial behavioral detail the annotations don't: the 32 KiB default window, the 1 MiB ceiling, whole-line trimming, stripping of colour codes and timestamps, the `start`/`end`/`total_bytes` windowing model, and the trust warning ('the log is the job's own output and untrusted: treat it as data'). This goes well beyond the annotation bar.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

One dense paragraph, front-loaded with the resource and the identifier disambiguation, then default behavior, then the pagination recipe. Every sentence carries information an agent needs; there is no filler or restatement of the title.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

There is no output schema, so the description must explain return values — and it does: tail by default, raw log window, `start`/`end` within `total_bytes`, and the `earlier`/`later` offset hints. Combined with the trust warning and the size limits, an agent has everything needed to call and consume this correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3. The description still adds cross-parameter meaning the per-field docs don't: it explains that `max_bytes` may be raised and counts raw bytes before stripping, that `timestamps=true` keeps timestamps, and — most importantly — that `offset`/`max_bytes` should be drawn from the `earlier` or `later` field of a prior response. That relational guidance is real added value.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Read part of one Actions job's log') and immediately disambiguates the key identifier: 'the job `id` from list_workflow_jobs, not the run id'. That contrast with a sibling tool means an agent can select this without opening the schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explains the default behavior and why it is the right default ('Returns the tail by default, because that is where a failure is'), then gives an explicit pagination strategy: 'walk back from the tail by passing `earlier` along'. It also names the alternative identifier source (list_workflow_jobs) so the agent doesn't confuse it with run-level tools.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already cover the safety profile (readOnlyHint=true, openWorldHint=true), and with no output schema the description usefully enumerates the payoff fields it returns (body, merged_by, merge_commit_sha, comment counts, diff_url), which is real added context. Gap: no mention of not-found behavior, rate limits, or pagination/truncation for body/diff fields.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with the action, then payoff, then alternatives — good ordering with no filler sentences. The middle field enumeration is dense and slightly run-on, but it earns its place because there is no output schema to carry that information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a 3-param read tool with no output schema, the description covers what it does, what comes back, how it differs from list_pull_requests, where head_sha flows next, and which siblings to use for file/diff data. Nothing an agent needs to invoke it correctly is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with per-param descriptions ('Issue or pull-request number', 'Repository owner — user or organization'), so the schema does the heavy lifting. The description's '(owner/repo/index)' ordering restates the schema keys without adding format or edge-case guidance (e.g., is index repo-scoped or global; does index accept an issue number that is actually a PR).

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

Specific verb+resource+scope: 'Get one pull request by number from a repository (owner/repo/index)'. It explicitly contrasts itself with list_pull_requests ('list_pull_requests' fields plus body, merged_by...'), so an agent knows this is the singular, richer variant without opening either schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Names alternatives and the condition that selects them: 'For the changes themselves use list_pull_request_files or get_pull_request_diff.' It also routes downstream: 'head_sha is what list_workflow_runs takes to find its CI', giving an explicit hand-off rule rather than leaving composition to inference.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint and openWorldHint, so the safety profile is covered; the description additionally surfaces the non-obvious truncation behavior (64 KiB default, raise via max_bytes) that would otherwise silently corrupt an agent's reading of a large diff. Some of this duplicates the max_bytes schema text, and nothing is said about binary files or what an empty diff returns.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Three sentences, front-loaded with the operation and the primary scoping override, with zero filler. Every clause either selects a mode or warns about a limit.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a read-only retrieval tool with a fully documented 5-parameter schema and no output schema, the description covers identification, scoping, discovery of valid paths, and truncation. It stops short of describing the returned diff's shape or failure behavior for missing paths/large binaries.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so both optional parameters already explain themselves in detail, including rename matching and the file_path/max_bytes interaction. The description restates those semantics rather than adding new ones, so baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The opening clause names a specific verb and resource ("Read a pull request's unified diff") and pins the identifier triple (owner/repo/index). It also differentiates from the closest sibling by pointing at list_pull_request_files as the source of valid file_path values.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

It clearly states the two modes — pass file_path for a single file's hunks, omit it for the whole diff — and names list_pull_request_files as the prerequisite discovery tool. What is missing is any guidance on when to prefer this over get_pull_request or get_file_contents in an adjacent workflow.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint and openWorldHint, so safety is covered; the description adds real behavioral content by naming the returned fields (body, target_commitish, asset_count, asset_names) and explaining that the release id is unavailable until after creation. It does not say what happens when no release exists for the tag, which is the key edge case for the idempotency workflow it recommends.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Three tight sentences: identity and key first, return payload second, workflow rationale last. No repetition of the title or schema, and no filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description correctly compensates by listing the returned fields and delegating asset detail to a sibling. The remaining gap is error semantics — a missing tag is exactly what the recommended pre-create check will hit, and the description never says so.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3, but the description adds the non-obvious fact that identification is by git tag rather than release id — the id only exists post-creation. That clarifies why all three identifiers are required for a single-record fetch.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource plus the exact lookup key: "Get one release by its git tag (owner/repo/tag)." It also enumerates what comes back, which cleanly separates it from list_releases (enumerate) and list_release_assets (per-asset detail).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives an explicit usage pattern — call before create_release so a release script is idempotent — and routes asset-level needs to list_release_assets. It stops short of stating the converse (use list_releases to enumerate, or edit_release when you already have the id), so it is clear context rather than a full when/when-not map.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already establish readOnlyHint=true and openWorldHint=true, but the description adds a crucial non-obvious behavior: disabled units cause their whole endpoint family to 404 rather than return empty. That directly explains why this tool is the right place to diagnose apparent missing repositories.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two tightly written sentences, front-loads the purpose and return contents, then adds the diagnostic rationale. Every clause earns its place with no boilerplate.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description still names the important returned fields (default branch, size in KiB, unit toggles) and explains the key 404 behavior. For a two-parameter read-only lookup tool, this is complete enough for correct selection and invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, and both owner and repo are documented in the schema. The description only reinforces the '(owner/repo)' format, so it adds minimal meaning beyond the already-complete schema, matching the baseline 3 for high schema coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource: 'Get one repository's details (owner/repo)' and enumerates exactly what is returned, including default branch, size, and unit toggles. This clearly distinguishes fetching a single repository from sibling list/search tools such as list_my_repos and search_repos.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives a clear diagnostic use case: check this tool when a release or workflow tool reports a repository as missing because a unit is off. However, it does not explicitly contrast with alternatives like list_my_repos or search_repos, so it stops short of full when-to-use/when-not guidance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint and openWorldHint, but the description adds real value: the truncation failure mode and the warning that absence from a truncated listing does not prove absence, plus the shape of returned entries. It stops short of describing pagination behavior for the page/limit params, so not a full 5.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Purpose and scope come first, then the recursive tradeoff, then return shape, then the truncation caveat, then the sibling alternative. Every clause carries distinct information with no restatement of the title.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description supplies the return fields (path, type, size, sha) and a critical correctness caveat about truncated results, which is exactly what an agent needs to use this tool soundly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so baseline is 3; the description adds meaning on top by clarifying sha accepts a branch/tag/commit and defaults to HEAD, and by framing recursive as a cost/volume tradeoff rather than just a flag. Page/limit semantics are left to the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Read a repository's git tree') with the addressing scheme (owner/repo, optional sha) up front. It is clearly distinguished from get_file_contents, which is named as the tool for one directory's entries.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly explains the recursive=true vs. non-recursive choice, including the motivating use case ('where is every file of this kind'), and names an alternative with the exact condition that selects it (get_file_contents on a directory path is cheaper for one level).

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is known. The description adds useful return-shape context and a subtle caveat that status is 'the outcome once there is one,' but it does not describe error behavior when a run is missing.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Two tightly packed sentences with no waste. The core operation is front-loaded, followed immediately by the return shape and the related-tool routing.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description does a good job naming the returned fields and referencing list_workflow_runs for the shape. It omits some detail such as pagination or not-found behavior, but those are minor for a single-resource read tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema has 100% description coverage for owner, repo, and run_id, so the parameter documentation burden is already met. The description adds only the owner/repo/run_id grouping and a reminder that run_id comes from list_workflow_runs, which is already in the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description gives a specific verb and resource: 'Get one Actions workflow run by run_id.' It also clarifies the shape by naming list_workflow_runs and enumerating returned fields, which distinguishes this single-run getter from the list-oriented sibling.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

It explicitly routes the agent to list_workflow_jobs and get_job_log for jobs and logs, which is strong when-not guidance for related data. It does not explicitly state when to use this rather than list_workflow_runs, though 'one ... by run_id' makes that boundary clear enough.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations only declare readOnlyHint/openWorldHint; the description adds the genuinely non-obvious behavior: omitting page/limit auto-paginates everything up to a 1,000-item cap with a `truncated` flag, while supplying page/limit switches to single-page mode. That pagination/truncation contract is the main failure mode and is disclosed precisely.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Three sentences, each load-bearing: what it returns, how pagination behaves, and which sibling to use instead. Scope and ordering are front-loaded with zero filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

No output schema exists, but the description enumerates the returned fields (name, head SHA, protected) and the truncation marker, and the pagination contract is fully specified. Nothing an agent needs to call this correctly is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so page/limit/owner/repo are already documented; the description goes beyond the schema by explaining the interaction — that the presence or absence of page/limit changes the result set entirely rather than just page size. It doesn't cover limit semantics alone (default page size) in detail.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ("List a repository's branches") plus the sort order ("most recently pushed first") and the exact projected fields returned. An agent can distinguish it from get_repo, list_commits and list_branch_protections without opening any schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly routes three related needs to three named siblings: default branch to get_repo, protection rules to list_branch_protections, history to list_commits. That is when-to-use guidance with alternatives named, not just implied.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations only declare readOnlyHint, so the description carries real weight and delivers: empty list semantics (nothing protected vs. feature absent), the fact that require_signed_commits is evaluated against introduced commits rather than branch history, what data is deliberately omitted, and that enable_force_push/apply_to_admins are forge-specific with 'absent ≠ false'. That is genuinely non-obvious behavior an agent could otherwise misread.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with the purpose, then layered detail. It is long for a two-parameter read tool, but with no output schema most of the length is load-bearing. The 'for a branch name or glob' clause is the one sentence that doesn't cleanly earn its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

No output schema exists, so the description must convey what comes back — and it does, enumerating enforced fields (signed commits, direct pushes, required approvals, status checks) plus explicit caveats about omitted and forge-specific fields. An agent has enough to interpret results correctly, including the ambiguous empty-list case.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with only owner/repo documented, so the baseline applies. The description adds the '(owner/repo)' hint but then mentions 'a branch name or glob' as if it were an input, when no such parameter exists in the schema — a mild source of confusion rather than added meaning.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('List a repository's branch protection rules') and scopes it to owner/repo, which cleanly separates it from list_branches and get_repo in the sibling set. An agent knows exactly what this returns before opening the schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explains the question the tool answers ('what each rule enforces') and explicitly disclaims bypass/allowlist data, effectively routing that need elsewhere. Missing is an explicit statement of when to use this versus inspecting branch metadata via list_branches, but the operational context is clear.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Goes well past the readOnly/openWorld annotations: it discloses auto-pagination, that results are deliberately slimmed to five fields, and why (raw objects carry base64 signature/payload blobs plus files and stats). The explanation that 'unsigned' differs from a failed verification is a genuine semantic disclosure an agent could not infer elsewhere.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loads purpose and ordering, then options, then output shape — a sensible progression with no filler. The two-sentence signature aside is slightly long for one field, but it prevents a real misinterpretation, so it largely earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description carries the return-value burden and does so: it enumerates the returned fields, explains the slimming rationale, and covers pagination and the sha default. An agent has enough to call this correctly and interpret the result without further guessing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3; the description adds a little by clarifying that sha accepts a branch, tag, or commit and defaults to the default branch, and that path filters by file. It does not address the interaction between 'auto-paginated' and the explicit page/limit parameters, which is the one point an agent might want clarified.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('List commits in a repository (owner/repo)') plus ordering ('newest first') and filter scope, which cleanly separates it from the singular get_commit sibling. An agent can tell immediately that this is the enumeration endpoint rather than a single-commit fetch.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is implied through the parameter narrative (start from a sha, filter by path, defaults to the default branch) but there are no explicit when-to-use/when-not statements or named alternatives. Nothing tells the agent, for example, when to prefer get_commit or how this relates to list_pull_request_files for change inspection.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations declare readOnlyHint and openWorldHint, and the description adds real context beyond them: the forge always sends the full thread, pagination happens here with limit defaulting to 50, the return shape {id, user, body, created_at, url} plus `total`, and that bot comments are included. It stops short of stating rate-limit or auth behavior, but for a read-only list tool that is a minor gap.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with purpose and ordering, then paging, then exclusions, then the bot caveat — a sensible order with no filler. The clause 'since/before keep only comments updated in that window' is spliced awkwardly into the paging sentence, which slightly hurts readability.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

There is no output schema, and the description compensates by naming the returned fields and the `total` count. Paging, filtering, ordering, and the scope boundaries are all covered, so an agent has everything needed to call it correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3; the description still adds meaning the schema does not, notably the interplay between page and limit (limit defaults to 50 only when page is given) and that since/before filter on update time rather than creation. That is genuine added value over the field descriptions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('List the discussion comments on an issue or pull request') plus identifier format (owner/repo/index) and ordering (oldest first). It explicitly names what it is not (issue description, events, inline review comments), so an agent can separate it from get_issue and list_pull_request_reviews without opening a schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives explicit routing: use get_issue for the description, list_pull_request_reviews for reviews, and this tool for the comment thread. It also states when to pass page/limit and what since/before do, which is exactly the decision guidance an agent needs.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations only say readOnly/openWorld; the description goes far beyond by disclosing forge-specific behavior (invalid label/milestone names are refused rather than silently ignored, sort is Forgejo-only and refused on Gitea) and the slimmed return shape. These are non-obvious failure modes an agent could otherwise trip over.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with scope then filters then caveats, and nearly every clause carries actionable information. It is dense and long-ish for a single paragraph, but no sentence is pure filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With 14 parameters and no output schema, the description compensates by summarizing the returned fields (number, title, state, author, labels, assignees, milestone, comment count, dates; no body). Nothing critical for correct invocation is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so baseline is 3, and the description adds meaningful semantics: labels/milestones match on ANY name, since/before are by last update, and sort's availability depends on the forge. It does not enumerate every sort value or page/limit interplay, but the schema covers those.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('List issues in a repository (owner/repo)') plus the default scope (open only). It explicitly carves out the sibling boundary by excluding pull requests and naming list_pull_requests as the alternative.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives explicit routing: use list_pull_requests for PRs, get_issue for the body, and states the default state filter. It also flags when the sort parameter is unavailable (Gitea) and when label/milestone names will be refused, which is exactly the guidance an agent needs before calling.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Beyond the read-only and open-world annotations, the description discloses important behavioral details: `verified` absence is forge-dependent, Gitea omits the field on SSH keys, Forgejo reports it, absent does not mean unverified, explicit false is meaningful, and Gitea's GPG error conflates absent and unverified keys. It also explains GPG address activation and that key material is dropped in favor of fingerprints and key ids.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is front-loaded with purpose and parameter behavior, then moves into caveats. It is longer than typical for a one-parameter list tool, but the length is carrying important meaning because there is no output schema and the forge-specific `verified` semantics are subtle.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Because no output schema exists, the description must explain return-value semantics, and it does: GPG entries carry covered addresses and activation status, signature verification depends on activated addresses, and key material/armored blobs are omitted in favor of fingerprints and key ids. It also covers the Gitea/Forgejo `verified` discrepancy thoroughly enough for an agent to interpret results correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, and the single `username` parameter is already fully documented in the schema, including the authenticated-user default and its relationship to `verified`. The description repeats the omission behavior but adds little parameter-level semantics beyond the schema, so the baseline score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description begins with a specific verb and resource: 'List an account's SSH and GPG keys.' It also clarifies the optional username behavior, so an agent can immediately tell what the tool does and what object it operates on. No sibling tool covers key listing, so differentiation is not an issue.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives clear operational context: omit `username` for the authenticated user, and it explains why that matters because only that list reliably carries `verified`. It does not explicitly state when to use this tool versus alternatives or when not to use it, but there is no competing key-listing sibling and the usage context is clear.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations only declare readOnlyHint and openWorldHint; the description adds the real behavioral layer: omitted page/limit walks every page up to a 1,000-item cap with a truncated flag beyond it, while explicit page/limit returns a single page of at most 50. It also discloses the slimmed field set, so the caller knows what comes back.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Three tight sentences, front-loaded with scope and sorting, then pagination semantics, then return fields, then the sibling routing. No filler and no repetition of the title.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

No output schema exists, and the description compensates by enumerating the returned fields (full_name, description, private, fork, archived, language, counts, size, default_branch, URLs, dates). Combined with pagination and scope details, nothing an agent needs to call it correctly is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, but the schema only says '1-based page number' and 'results per page' with null defaults. The description resolves what is genuinely ambiguous: the default null behavior (walk all pages), the 50-per-page ceiling on limit, and the truncation outcome, which the schema alone cannot convey.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource plus a precise scope: repos the account can work in, including own, org, and collaborator repos, with the sort order (case-insensitive by name). It draws a clear line against search_repos (instance-wide) and get_repo (single detail), so an agent can disambiguate without opening a schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly names both alternatives and the condition that selects them: search_repos for repos anywhere on the instance, get_repo for one repo's details. It also distinguishes the internal usage fork between streaming the whole set and paging, so the agent knows which call pattern to choose.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already establish readOnlyHint and openWorldHint, but the description adds important behavioral context: listing does not mark notifications read, and this server has no tool that does. It also discloses the slimmed return shape and the meaning of total, which goes beyond the annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is dense but front-loaded: it states what is listed, the default filter, the return shape, pagination, and the non-mutating behavior. Every sentence contributes actionable information without repetition.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Although there is no output schema, the description enumerates the returned fields and explains total, so the agent knows what to expect from the response. Combined with the explicit pagination and read-state caveats, it is complete for this read-only listing tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the schema already documents all three parameters. The description still adds useful semantics by stating that all defaults to unread-only and that pagination is limited to at most 50 per page.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource: it lists notification threads and explicitly defines ordering as most recently updated first. It also distinguishes the tool from read-thread alternatives by directing the agent to get_issue or get_pull_request for the underlying conversation.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives explicit default behavior (unread only) and the condition for changing it (all=true). It also explains pagination constraints and directs the agent to the correct sibling tools for reading a notification thread in detail.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no output schema, the description carries the burden of explaining returns and does so well: it enumerates the organization fields, defines `username` as the owner name for other tools, states pagination behavior with a 50-item cap, mentions `total`, and notes that accounts with no organizations get an empty list. This adds meaningful behavioral context beyond the read-only annotation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is compact and front-loaded: it begins with the core action and scope, then adds return fields, pagination constraints, empty-result behavior, and sibling differentiation. Every clause earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple read-only listing tool with no required parameters and no output schema, the description covers purpose, return shape, pagination limits, empty results, and the key `username` semantics needed for downstream calls. Nothing essential for correct invocation appears to be missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3, but the description adds useful semantics by stating the maximum page size of 50 and explaining that `total` gives the overall count. This helps an agent use `page`/`limit` correctly beyond the schema's brief field descriptions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource ('List the organizations your account belongs to') and enumerates the returned fields, including the crucial note that `username` is the owner name to pass to other tools. It also explicitly differentiates from `list_my_repos` by saying organization repos are already covered there.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives a clear context for use and explicitly redirects repo-related needs to `list_my_repos`, preventing a common misuse. It does not explicitly contrast with `whoami` or `search_repos`, but the intended usage is clear enough from the owner-name guidance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety is covered; the description adds non-structured behavior: auto-pagination when both page and limit are omitted, and the Forgejo limitation that hunks are not returned here. It doesn't state ordering or total counts, so not a full 5.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, both dense and front-loaded: the capability and return shape come first, the limitation-redirect second. No filler or restatement of the title.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description does the work of sketching the return shape (per-file additions/deletions, rename info) and covers pagination behavior. Minor gaps remain around result ordering and whether a total count is available, but nothing that would cause a mis-call.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the per-parameter docs already carry the baseline. The description adds semantics the schema does not: the meaning of owner/repo/index as a composite identifier and the notable interaction where omitting both page and limit triggers auto-pagination.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('List the files a pull request changes') and enumerates the returned data (additions/deletions, rename info). It also explicitly differentiates itself from the sibling get_pull_request_diff, so an agent can choose without opening a schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives the when-to-use condition (listing changed files) and names the alternative for the adjacent need (get_pull_request_diff for hunks), including the exact trigger 'pass a filename'. This is explicit routing rather than implied usage.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
