Traceability audit

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

No annotations are provided, so the description carries the full burden. It discloses the concrete checks (commit format, Authored-by trailer, Git Note presence, subtask file contracts, reviewer/author separation), which is real behavioral value, but it never states that the operation is read-only/non-destructive, what the result looks like, or how failures are reported.

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 with no filler; each listed item corresponds to a real check. Slightly dense but appropriately sized for the tool's scope.

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 and no annotations, the description should say more about what the audit returns (pass/fail per check? report text?) and whether it mutates anything. The enumeration of checks helps, but return-shape and side-effect expectations remain unspecified.

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?

Only one parameter, baseBranch, and schema coverage is 100%, with the default ('main' with origin fallback) already documented in the schema. The description adds nothing about how the branch is used in the comparison, so baseline 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?

Specific verb ('Audit') plus resource ('branch commits against the LogNexus review gate') and an explicit enumeration of the five checks performed. An agent knows exactly what the tool inspects, though nothing distinguishes it from siblings like lognexus_status or lognexus_commit.

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?

No statement of when to run this audit, whether it is a pre-commit gate check or a post-hoc review, or how it relates to the many sibling tools (lognexus_commit, lognexus_status). Usage must be inferred entirely from the name and checklist.

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