Re-scan and diff against a prior scan

codeinspectus_rescan
Read-onlyIdempotent

Re-run a scan after fixes and diff against a prior scan to report resolved, remaining, and new findings. Verify fixes without writing to your repo.

Instructions

Re-run a scan after fixes were applied and diff against a prior scan_id (or the most recent scan of the same path). Reports which findings are resolved, which remain, and which were newly introduced, plus fresh technology and native-pack execution coverage. Repository-trust artifacts are diffed separately with fail-closed resolved, remaining, introduced and not-rechecked states. Use this to verify approved fixes. Never writes to your code or repo.

A4.1/5.0
Behavior4/5

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

Annotations already declare readOnly/idempotent/non-destructive, and the description reinforces this with 'Never writes to your code or repo'. Beyond that it adds real behavioral context: the diff states reported, the fail-closed handling of trust artifacts, and the not-rechecked state. It stops short of describing pagination or output shape, but adds meaningful value over the annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The core action and diff semantics are front-loaded, and the closing 'Never writes' caveat earns its place. Some phrasing is jargon-dense ('native-pack execution coverage', 'fail-closed resolved, remaining, introduced and not-rechecked states'), which mildly taxes readability but remains informative.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return values need not be explained, and annotations cover the safety profile. The description fills in the diff behavior and trust-artifact handling well; only the undocumented scanner/filter parameters leave a small gap.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is only 40%, so the description must compensate. It clarifies prior_scan_id's default (most recent scan of the same path), which mirrors the schema, but offers nothing on scanners, max_findings, or severity_threshold. With half the parameters undocumented in both places, this lands at the baseline 3.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (re-run a scan and diff) and resource (scan), with the diff scope made explicit. It also implicitly distinguishes itself from codeinspectus_scan by being the post-fix re-scan rather than a fresh baseline, so an agent can tell the two apart.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives a clear when-to-use trigger ('after fixes were applied', 'to verify approved fixes') and explains the default prior-scan selection. It never explicitly names codeinspectus_scan as the complement, so the alternative isn't spelled out, keeping it below a 5.

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