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

With no annotations, the description carries the full burden, and it does disclose some behavior: defaults for every parameter, the persona fallback, and the return shape (path + summary). It does not state whether an existing output file is overwritten, what permissions or repo state are required, or that this performs file-system writes — meaningful gaps for a side-effecting 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?

Front-loads the one-line purpose, then uses Args/Returns blocks, which matches how the schema is organized. Slightly verbose in the persona_file entry but every line carries information; 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?

Covers all parameters and the return value, and an output schema exists so return detail is not strictly required. The remaining gap is workflow placement — when to run this relative to the review_* siblings — for an agent orchestrating a multi-step review.

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 0%, so the description must compensate, and it largely does: all four parameters are explained with defaults (base_branch=development, output_file=.code_review.md) plus a concrete persona_file example path. Minor gaps remain, e.g., accepted formats for output_file and relative-vs-absolute path handling.

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 artifact: 'Generate a comprehensive code review report as a markdown file.' That distinguishes it from siblings like review_diff and review_file, which analyze rather than produce a report artifact. However, it never explicitly names those siblings or contrasts the workflows, so difference must be inferred.

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?

There is no when-to-use framing: nothing says whether this is the final aggregation step after review_diff/review_file, or what prerequisites (e.g., changed files needing review) exist. The Args section describes inputs but gives no selection guidance against get_review_checklist or review_diff.

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 annotations, the description carries the full behavioral burden. It does not state whether the operation is read-only (though 'Get' implies it), nor does it mention permissions, rate limits, or side effects. The 'Returns' section adds some value by describing the output as the git diff output, but overall behavioral disclosure is thin.

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 uses an Args and Returns structure that is clear but somewhat verbose for a simple diff tool. It front-loads the purpose, which is good, but the parameter details could be more compact. Overall, it is acceptable but not highly polished.

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 that the tool has an output schema (which likely explains return values), the description need not detail them extensively. It covers parameters adequately but lacks behavioral context (e.g., read-only nature) and usage differentiation from siblings. For a tool with no annotations and 0% schema coverage, it is minimally complete but leaves gaps.

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 0%, so the description must compensate for undocumented parameters. It does so by explaining each of the three parameters: base_branch (default development), file_filter (default *.py for Python files), and working_directory (defaults to current directory). This adds meaningful semantics beyond the raw schema, though it could clarify the format of file_filter patterns or the effect of null.

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 verb and resource ('Get the git diff between the current branch and a base branch'), which is clear enough. However, it does not distinguish itself from siblings like get_changed_files or review_diff, which likely operate on similar diff data. The purpose is understandable but not differentiated from alternatives.

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?

There is no explicit guidance on when to use this tool versus siblings such as get_changed_files or review_diff. The description implies usage through context (comparing branches) but provides no when/when-not conditions or 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?

No annotations are provided, so the description carries the burden; it partially discharges it by disclosing defaults. The default file_filter of *.py is a meaningful behavioral trait (non-Python changes are silently excluded) and the default base branch of development is useful. It does not state read-only status, permissions, or limits, so it remains incomplete for a no-annotation 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?

The Args/Returns structure is front-loaded with the core purpose and economical. The Returns line is redundant given an output schema exists, but overall there is little waste.

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 only three optional parameters and an output schema present, the description covers the essentials: what it returns and what each argument means. The main gap is that the *.py default silently narrowing results is not flagged as a caveat the agent should override.

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 0%, so the description must compensate, and it does: all three parameters are named with their defaults and purpose. It stops short of giving format examples (e.g., glob syntax for file_filter or branch naming conventions) that would fully remove ambiguity.

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 (get) and resource (changed files) with a clear scope: the current branch. However, it never distinguishes itself from siblings like get_branch_diff or review_diff, which sound like they cover overlapping ground, so an agent must guess which to pick.

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 only implied by the name and the 'compare against base_branch' framing. There is no when-to-use guidance and no mention of alternatives such as get_branch_diff, which appears to overlap heavily. An agent is left to infer the selection criteria.

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 annotations, the description carries the full burden. It does disclose the key behavioral fact that omitting persona_file falls back to a default persona, and that it returns full content, but says nothing about error behavior (e.g., missing file), whether the path is resolved against working_directory, or that the call has no side effects.

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 purpose and usage in the first two lines, then uses conventional Args/Returns sections. Slightly padded by docstring formatting, but every line 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?

For a simple two-optional-parameter read tool with an output schema already covering the return shape, the description covers purpose, usage, parameter meaning, and defaults. Only edge-case behavior (missing file, path resolution) is left implicit.

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 0%, so the description must compensate and largely does: it explains persona_file's purpose, format, an example path, and its default fallback, plus working_directory's role and default. It omits only finer details like path resolution rules and relative-vs-absolute handling.

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 ('Get the code reviewer persona') and clarifies the scope ('that will be used for reviews'). It distinguishes itself from action-oriented siblings like review_diff by framing itself as a pre-review inspection step, though it never names a sibling directly.

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?

'Use this to view or verify the persona before running a review' gives clear context for when to invoke it relative to the review workflow. It stops short of naming alternatives or exclusions, but the usage window is unambiguous.

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?

No annotations are provided, so the description carries the full behavioral burden. It hints at a persona dependency and a return value, but says nothing about where the persona comes from, permissions, or whether the checklist varies per invocation.

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 short sentences with the Returns section clearly appended. Front-loaded and with no waste, though the Returns line is somewhat redundant given an output schema exists.

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 an output schema present, return explanation is unnecessary, and there are no parameters to cover. However, the implicit dependency on a persona (presumably from get_persona) is left unexplained, which is the key missing 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?

The tool takes zero parameters, so the baseline is 4. The description's mention of a persona-driven result adds a small amount of meaning about what determines the output, but there are no parameters to document.

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: retrieving the code review checklist. The phrase 'based on the persona' distinguishes it from a static list, but it does not explicitly differentiate from siblings like review_file or generate_review_report.

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?

No when-to-use guidance, no prerequisites, and no mention of alternatives. An agent must infer that this precedes manual review and depends on a persona.

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?

No annotations exist, so the description carries the full burden; it does convey that this is an analysis/read operation producing feedback rather than a mutation, which is useful. However, it omits any statement about prerequisites (must be inside a git repo), side effects, whether it writes anything to disk, or latency/cost characteristics.

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 core purpose in the first line, then an Args/Returns breakdown that earns its space given the 0% schema coverage. Slightly padded by the two-sentence preamble, but nothing is genuinely wasted.

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 an output schema present, the description need not detail return values, though it still does briefly ('comments organized by file and category'). Combined with full parameter documentation, an agent has enough to invoke it correctly, with only cross-tool routing left unresolved.

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 0%, so the schema alone leaves all four parameters undocumented. The description compensates fully: it explains base_branch's meaning and default, working_directory's default, enumerates the valid focus_areas values ('types', 'docs', 'style', 'errors', 'performance', 'architecture', 'all'), and gives a concrete example path for persona_file plus its fallback behavior.

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: reviews the git diff of the current branch against a base branch and returns structured feedback. It is clearly a diff-level reviewer, but it never distinguishes itself from siblings like review_file or generate_review_report, so an agent must infer the split.

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 by 'analyzes the diff between your current branch and the base branch,' which tells the agent when the tool is applicable. There is no explicit when-not guidance and no mention of review_file as the alternative for single-file review, so routing between siblings 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?

No annotations are provided, so the description carries the full behavioral burden. It says nothing about whether this is read-only, whether it invokes an LLM, latency/cost, permission needs, or what happens if persona_file is missing or invalid; the 'Returns' line is largely redundant given an 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?

Purpose is front-loaded in one sentence, followed by a compact Args/Returns block. The persona_file example is the only mildly verbose element and it earns its place by clarifying the expected path format.

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?

The output schema covers return values, so the 'Returns' line is unnecessary, and parameters are well documented. However, with no annotations at all, the definition omits key operational context (side effects, persona resolution behavior, failure modes), leaving it adequate but incomplete.

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?

With 0% schema description coverage, the description must compensate, and it does: it explains file_path accepts relative or absolute paths, working_directory defaults to the current directory, and persona_file points to a custom persona markdown with a concrete example and a default fallback. Only minor gaps remain (e.g. no stated constraints on file_path).

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 (review) and resource (a specific file), which implicitly separates it from the sibling review_diff that operates on a diff. It does not explicitly name a sibling tool, so it falls short of the top score, but the scope is unambiguous.

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 only implied: the presence of a required file_path suggests reviewing one file at a time, and persona_file suggests customization. There is no explicit guidance on when to prefer this over review_diff or generate_review_report, nor any prerequisite (e.g. persona file must exist).

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