detect_project_environment

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

With no annotations, the description carries the full burden; it usefully discloses that detection is local and network-free, which is real behavioral value. However it omits failure/error behavior (e.g. missing package.json), whether it is strictly read-only, and any output shape, leaving notable gaps for an unannotated 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?

A single front-loaded sentence opens with the verb and then enumerates the detectable items. The parenthetical lists are dense but each item is informative, so nearly every token 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 one-parameter tool with no output schema, the description enumerates what will be detected, which effectively conveys the return content. It is nearly complete, missing only error conditions and confirmation that the operation is non-mutating.

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?

There is a single parameter at 100% schema description coverage, so the schema already documents project_path fully. The description adds only the loose notion of 'local project files' and no syntax or format detail 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?

States a specific verb ('Detects') and enumerates the exact resources: Node.js runtime, package manager, locked dependency versions, and specific config paradigms. The read-only, local-only framing ('from local project files') clearly separates it from the sibling tools, which concern compatibility checking, setup guides, and upgrade steps.

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 phrase 'from local project files without network calls' implies a first-step, offline detection context, but the description never states when to reach for this tool versus siblings like check_dependency_compatibility or get_upgrade_steps. Usage is inferable but not explicit.

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