threads_manage_pending_reply

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

No annotations are supplied, so the description carries the full burden. It usefully discloses one state transition ('Ignored replies can still be approved later') and that approve publishes the reply, but says nothing about whether an approval can be reversed, what permissions are required, or what the call returns.

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?

Two short sentences, zero filler, with the operational condition front-loaded before the lifecycle note. Every sentence earns its place.

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 two-parameter mutation with no annotations and no output schema, the description covers the precondition and the ignore outcome but not the return value, error conditions, or reversibility of approval. Adequate to invoke, incomplete for an agent's confidence about side effects.

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 description coverage is 100% — the approve and reply_id parameters are already fully documented in the schema (approve=true approves/publishes, false ignores). The description adds only the framing verb pair and no syntax, format, or edge-case detail beyond the schema, so the 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?

States a specific verb pair plus resource ('Approve or ignore a pending reply') and names the gating condition ('post with reply approvals enabled'), which separates it cleanly from the read-side sibling threads_get_pending_replies. It does not explicitly distinguish itself from adjacent moderation tools like threads_hide_reply, so it stops just short of 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?

The phrase 'with reply approvals enabled' is a real precondition that tells the agent when this tool applies. It gives no exclusions or named alternatives (e.g., use hide_reply for already-published replies), so the agent must infer the boundary with the hide/unhide siblings.

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