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

With no annotations to lean on, the description carries the burden well: it discloses the backend pipeline (stores, filters by security profile / ignore-unfixed, dedupes, inserts SECURITY bugs) and an important side-effect boundary (does not mark the scan COMPLETED). It omits auth/permission requirements and whether re-uploading a report is idempotent despite dedupe.

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 tight sentences, front-loaded with the core action and invocation, followed by pipeline behavior and the critical 'does not mark COMPLETED' caveat. No filler or restatement of the name.

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 write tool with no annotations and no output schema, the description covers purpose, mutation effects, and the downstream workflow step. It leaves the return value and the meaning of 'id' unstated, which is a minor gap since no output schema exists to cover responses.

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% and both parameters (id, reportFile) are required, so the description must compensate. It maps the params to '--id' and '--report-file <path>' and implies the file is a filesystem path, but does not explain what the id identifies (scan id?) or any format/collision constraints. Baseline-level adequacy given the 0% 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?

States a specific verb+resource ('Upload a full Trivy JSON report for a dependency security scan') that distinguishes it cleanly from the sibling report-sast-findings, report-dast-findings, and report-secrets-findings tools. An agent can tell which scanner's findings this handles 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 concrete invocation guidance ('Pass --id and --report-file <path>') and a clear workflow boundary: it does not mark the scan COMPLETED, and update-scan-progress must be called afterward by the deps playbook. It stops short of naming sibling alternatives or stating when a different reporting tool is appropriate, so it is 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.
