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

No annotations are provided, so the description must carry the full burden. It mentions conditions and paths but does not disclose what happens when invalid inputs are given, whether edges can overwrite existing ones, or any validation behavior. It also doesn't mention the return value or 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?

The description is concise and well-structured: an introductory sentence followed by bullet-like lines for each edge type. Every sentence adds value, and the most important information (how to specify each type) is front-loaded.

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 tool has an output schema, but the description doesn't mention what the tool returns, which might be important for agents. It also lacks behavioral details like validation or error handling. Given the complexity of conditional edges, the description covers the main usage but misses edge cases and side effects.

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 schema description coverage at 0%, the description must compensate for all parameters. It does explain 'to', 'condition', and 'paths' in context (e.g., 'to' is a node id or END), but it does not explain 'project_dir' and 'from_' at all. The description adds value for some parameters but leaves others undocumented.

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 clearly states the tool adds an edge between nodes and distinguishes between simple and conditional edges, which is a specific verb and resource. However, it does not explicitly contrast with siblings like remove_edge, but the purpose is clear enough.

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 provides clear guidance on when to use simple vs conditional edges, explaining the required parameters for each case. It does not explicitly mention alternatives, but the context is sufficient for an agent to decide which parameters to set.

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 burden. It discloses two important behaviors: config['function'] defaults to node id, and the first node auto-becomes entry point. However, it does not disclose whether 'update' overwrites existing config, whether it validates the callable exists, or any side effects on edges.

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-loads the primary action, then explains the two non-obvious behaviors. Every sentence earns its place, though the entry-point rule could be more concise.

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 tool has an output schema and 5 parameters, but no annotations. The description covers the most subtle behaviors (config function resolution and entry point designation) but omits update semantics, error conditions, and relationship to project initialization. Adequate for basic use, incomplete for edge cases.

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. It explains config['function'] and entry_point semantics, but leaves id, type, and project_dir meanings to the schema. The description adds value for two of five parameters, which is partial compensation.

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 clear verb+resource ('Add or update a node') and explains the key config['function'] behavior, which distinguishes it from graph-structure tools like add_edge/remove_node. It doesn't explicitly contrast with siblings, but the resource and behavior are specific enough to be identifiable.

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 implies usage context: it is for adding/updating nodes, and the entry-point rule tells when to use entry_point=True. However, it does not explicitly state when to prefer alternatives like remove_node or validate_graph, nor does it mention prerequisites like project initialization.

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 provided, this description carries the full behavioral burden. It discloses atomicity ('Nothing is written if any operation is invalid'), ordering ('applied in order'), persistence ('saved once at the end'), automatic entry_point derivation, and the compact summary return. This is a thorough behavioral contract for a mutating batch 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 description is moderately long but every sentence carries instructional weight: usage guidance, atomicity, operation format, entry_point caveat, and return behavior. The front-loaded purpose and clean example block make it easy to scan, 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?

Given the tool's complexity (multi-operation batching with atomic semantics) and an existing output schema, the description covers all necessary operational details: operation set, ordering, atomicity, entry_point handling, and post-call guidance. An agent can invoke it correctly and predict its side effects without needing additional information.

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%, but the description compensates richly for the `operations` parameter with a full format spec and concrete examples for add_node, add_edge, remove_node, remove_edge, and set_state_schema. However, `project_dir` is never explained beyond its name in the schema, leaving a small gap in an otherwise strong parameter narrative.

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 'Apply several spec edits in one call' and explicitly contrasts with individual add_node/add_edge calls, naming the sibling tools it replaces. This makes the batch-mutation purpose unmistakable and differentiates it from the single-edit 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?

It gives a clear when-to-use rule ('whenever wiring more than one node/edge at once') and mentions the alternative of separate calls. It also explains when not to fabricate a START edge, and routes to get_spec for full results, leaving no ambiguity about selection or follow-up.

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 provided, the description carries the full burden of behavioral disclosure. It clearly declares the operation is read-only, explains that the return is the full spec rather than a summary, and gives the design rationale about per-edit response cost. It does not discuss error conditions or permissions, but the core behavioral traits are well covered.

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 core purpose and then adds a tightly relevant paragraph explaining the contrast with mutating tools. Every sentence earns its place, and there is 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?

For a simple one-parameter read-only tool with an output schema available, the description covers the main behavioral context: what it retrieves, when to call it, and how it differs from siblings. The missing parameter documentation is a minor gap given the self-explanatory project_dir name, but the tool is otherwise fully understandable.

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%, and the description does not mention project_dir at all. The parameter name and title ('Project Dir') give some minimal hint, but the description fails to compensate for the absence of schema documentation, such as what the path should point to or any required format.

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 and resource: "Read-only fetch of the full current spec." It also distinguishes itself from sibling mutating tools by noting they return compact summaries, making it clear this tool provides the complete graph state.

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 explicitly states when to use this tool: "Call this when you actually need the whole picture." It also explains that mutating tools (add_node, add_edge, remove_node, remove_edge, set_state_schema) return only counts, which tells the agent when those alternatives are more appropriate.

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 provided, the description carries the full burden of behavioral disclosure. It explains that project_dir is created if missing, errors if spec.yaml already exists, and details how name and state_fields are used. It does not mention whether other files are overwritten or permissions required, but the error condition on spec.yaml suggests safe creation. This is reasonably transparent for a scaffold 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 description is compact and front-loaded with the core purpose, followed by parameter explanations. Each sentence carries necessary information—creation artifacts, error condition, and parameter details. It is slightly verbose in the parameter block but remains efficient and well-structured.

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 an initialization tool with an output schema (not shown), the description covers all necessary aspects: purpose, parameters, error behavior, and file outputs. It does not mention what the return value looks like, but since an output schema exists, that is acceptable. It could be more explicit about side effects (e.g., creating directories) but overall it is complete for correct 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?

The schema has 0% description coverage, so the description must fully compensate. It does: each parameter (project_dir, name, state_fields) is explained with its role, constraints, and expected structure (e.g., state_fields items have name, type, reducer?, default?). This adds meaning far beyond the bare schema titles.

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 clearly states the tool creates a new spec-driven LangGraph project and enumerates the artifacts it generates (spec.yaml, nodes.py stub, __init__.py). This distinguishes it from sibling tools that modify or inspect an existing project, so an agent can immediately recognize it as the setup/initialization tool.

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 implies usage for new projects by noting that an error occurs if spec.yaml already exists, which effectively warns against reuse. However, it does not explicitly state when to prefer this tool over siblings (e.g., 'use for initial scaffolding') or mention any alternatives. The error condition provides partial guidance but the exclusion logic is left 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?

With no annotations, the description carries the full burden of behavioral disclosure. It reveals a key behavioral nuance: omitting `to` removes all edges from the source, which is not obvious from the schema alone. However, it does not mention error handling, side effects, or what happens if the edge or node does not exist.

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 extremely concise: two sentences with zero filler. The primary action is front-loaded, and the optional behavior is stated immediately after, making it easy for an agent to parse quickly.

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 mutation tool, the description covers the core behavior and the optional parameter's effect. The output schema exists, so return values are not needed. The only gap is the unaddressed `project_dir` parameter and edge-case behavior, but these are minor for this tool's complexity.

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. It explicitly explains the `to` parameter (optional, and omission removes all edges), and `from_` is clearly implied as the source node. However, `project_dir` is not explained, leaving its purpose unclear despite being required.

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 clearly states the action: 'Remove edge(s) from a source node.' It specifies the verb (remove), the resource (edge), and the context (source node), distinguishing it from sibling tools like remove_node and add_edge without ambiguity.

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 provides a usage hint for the `to` parameter ('Omit `to` to remove all edges'), but it does not explicitly state when to use this tool versus alternatives like remove_node or add_edge. The usage is implied by the name and description rather than directly addressed.

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 behavioral disclosure burden. It meaningfully discloses that the operation is destructive to edges as well as the node, which is the most important side-effect. It does not discuss failure behavior or irreversibility, but the core cascading behavior is clearly stated.

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 sentence, front-loaded with the primary action and immediately followed by the critical side-effect. Every word earns its place; there is no filler or 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?

For a simple two-parameter tool with an output schema, the core semantics are covered. However, the description leaves project_dir's role and the node-identification semantics implicit, and it does not state what happens if the node does not exist. This is acceptable but not fully complete.

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%, and the description adds no meaning to either parameter. 'id' and 'project_dir' are only explained by their names, so an agent must infer that 'id' identifies the node and 'project_dir' locates the containing project. The description should have compensated for the missing parameter docs.

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 ('Remove a node') and the key side-effect (cascading deletion of edges). It is clearly distinguishable from sibling tools like remove_edge, since it targets a node and explicitly handles edge cleanup.

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 rather than explicit: the 'cascading' phrase suggests this is the right tool when both a node and its touching edges should be removed, versus remove_edge for edges alone. No explicit when-to-use or when-not-to-use guidance is provided, but the context is inferable.

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 provided, the description carries the full burden and does add meaningful behavioral context: deterministic Jinja2 templating, no LLM involvement, and error-blocking versus warning-tolerant rendering. It does not explicitly describe file overwriting or other side effects, but the default output path and rendering behavior are clearly disclosed.

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 three short, meaningful sentences with the core purpose front-loaded. The second sentence about determinism and validation behavior earns its place and adds no fluff.

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?

An output schema exists, so return-value documentation is not required. However, for a tool with no annotations that appears to write files, the description does not state how project_dir and output_path interact or whether an existing graph.py is overwritten. It covers validation behavior well but lacks full file-handling 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 0%, so the description must compensate for undocumented parameters. It only clarifies the output_path default via 'graph.py by default' and leaves project_dir and custom output_path behavior largely unexplained. This is partial compensation at best.

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 clearly states a specific action and resource: rendering the current spec into idiomatic LangGraph Python, defaulting to graph.py. This distinguishes it from sibling tools like get_spec and validate_graph, which inspect or validate rather than generate code.

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 implies the tool should be used after the spec is valid, since it blocks on validation errors, but it never explicitly says when to use it or when to prefer a sibling tool. No alternatives or exclusions are 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?

No annotations are provided, so the description carries the full disclosure burden. It does convey the destructive nature ('replace wholesale') and documents the field contract ({name, type, reducer?, default?}) plus the type/reducer syntax. However, it omits error behavior (e.g., invalid Python type expressions), validation of the schema, and side effects on nodes referencing old fields. The documented field structure adds genuine value, but coverage is incomplete.

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 with the core purpose front-loaded in the first sentence and supporting field details in the following two. No filler or redundant phrasing; each sentence 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?

An output schema exists, so return-value documentation is not required. The description covers the input contract for 'fields' but lacks error-condition disclosure and side-effect context (what happens to existing nodes or references after a wholesale schema swap). For a schema-replacement mutation, this is a meaningful gap, though the tool has only two parameters and moderate complexity.

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 substantially for 'fields' by defining each sub-field's shape and the exact syntax of 'type' and 'reducer' with examples. However, 'project_dir' receives zero explanation—no hint that it is the project path or how it is used. The main parameter is richly documented, but one of the two required parameters is ignored.

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+scope: 'Replace the graph's state schema wholesale.' This clearly distinguishes it from sibling tools like add_node/add_edge (which mutate graph structure) and init_project (project setup). The 'wholesale' qualifier precisely conveys full replacement, making the purpose 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?

The description states what the tool does but gives no guidance on when to choose it over alternatives, and never names a sibling or an exclusion condition. There is no mention of when incremental updates would be preferable or when this wholesale replacement is appropriate. Usage context is entirely implied by the purpose.

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 provided, the description must carry the burden of behavioral disclosure. It explains that the tool returns ok=False if errors are found, and distinguishes errors from warnings, which is useful. However, it doesn't specify what 'errors' vs 'warnings' mean in this context, nor does it explain whether the tool performs any side effects (likely none, but it's not stated). Since it's a validation tool, it's presumably read-only, but that's implicit, not explicit.

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 sentences, with the first sentence defining the purpose and the second detailing the return behavior. It's concise, front-loaded with the action and scope, and every phrase adds value. No redundant 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?

The tool is a validation function with a single simple parameter and an output schema (which likely describes the return structure). Given its complexity, the description covers the core functionality (what is validated, what the result means). It doesn't provide examples or elaborate on warning vs error categories, but for a validation tool, this is reasonably complete. The output schema exists, so return details are structured elsewhere.

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 0% description coverage for the only parameter 'project_dir', so the description must compensate. The description does not explain 'project_dir' beyond its name, but the name is self-explanatory (the directory containing the spec). Given the parameter's simplicity, the missing explicit description is a minor gap. Still, the description doesn't add any additional meaning beyond the schema, but the schema itself is minimal, so the baseline is 4 due to low 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 clearly states a specific verb ('validate') and resource ('the spec'), and lists the specific error types it checks for (unreachable nodes, missing paths to END, dangling conditions/edges, duplicate/typo'd ids). This distinguishes it from sibling tools like get_spec or init_project, though it doesn't explicitly name a 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?

The description implies when to use it (when you need to validate the spec for errors), but it doesn't explicitly state when to use it versus alternatives or when not to use it. It also doesn't mention typical triggers like 'after making changes' or 'before rendering'. The context is clear enough but lacks explicit routing guidance.

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