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

Annotations already cover safety (readOnly, idempotent, non-destructive) and the description goes well beyond them: it explains that conflicts are graded on semver ranges rather than version strings, defines what error vs warning mean, and notes each conflict carries a one-sentence summary. Since no output schema exists, this semantic detail is valuable for interpreting results.

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 before the mode distinction and the grading semantics. It is dense but almost every sentence carries information; only the semver-range restatement is slightly redundant.

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 burden of explaining returns, and it does so adequately for the conflict mode (grading, error/warning, summary field). The single-service package-list shape is left less specified, but 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% and all three parameters are documented there. The description restates the key behavioral distinction (omitting service yields org-wide analysis) but adds 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 and resource (read npm dependencies) and clearly enumerates its two modes: one service's package list, or org-wide conflicts when service is omitted. It is not explicitly differentiated from related siblings like check_compatibility or get_service_graph, which keeps it just below a 5.

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 trigger: "Call it before adding or bumping a package." It also states the condition that selects org-wide mode (omit the service). No explicit when-not or named alternative is given, 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.
