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

With no annotations, the description carries the full burden and does so extensively: it discloses that locked/retiring pages have edits stripped on read, that stale inputs omit the plan while preserving the stored brief, that edgeStatus is a suggestion not a measurement, that format 1 briefs cannot be drafted from, and that claimCheck annotates but never changes the brief (read-only semantics).

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?

The core purpose is front-loaded in the first sentence, which is good. However, the remainder is an extremely dense run-on covering formats, edge cases, and claim checks, making it hard to parse; much is genuinely necessary because there is no output schema, but the structure could be broken into digestible units.

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 a single simple input, the description must carry the return-value burden, and it does: it details both brief formats, the structured brief fields, evidence objects, the inboundLinkPlan, and claimCheck contents. An agent has enough to interpret results correctly.

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 (actionId) with 100% schema description coverage, so the schema already documents it fully. The description adds no extra meaning about the parameter, which matches the baseline of 3 when the schema does the heavy lifting.

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?

The opening sentence gives a specific verb+resource ('Get the stored brief for a specific action') and enumerates what the response contains (readiness status, cut-short research, credits, timestamp, the brief). It is clearly distinguishable in spirit from devtune_generate_action_brief and devtune_get_action_draft, but it never names those siblings or explicitly contrasts retrieval with generation/drafting.

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?

There is no explicit when-to-use, when-not-to-use, or alternative-selection guidance; the text dives straight into return-shape details. At best the agent can infer 'read a brief' from the purpose, but nothing tells it whether to call this versus generate_action_brief or get_action_draft.

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