claude_codex_login_status

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

Discloses that no secrets are exposed, which is an important safety trait. However, with no annotations, further behavioral details (e.g., idempotency, side effects) are missing.

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?

Single concise phrase, no wasted words, front-loaded with key identity and caveat.

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 parameterless status tool, the description is nearly complete. Could optionally hint at output structure, but not required given simplicity.

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?

No parameters exist, so schema coverage is 100%. Description adds context by clarifying it's about OAuth credentials and safe (no secrets).

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 description clearly states it returns OAuth credential status, and the phrase 'no secrets' distinguishes it from sibling tools like claude_codex_login_refresh which might handle credentials.

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?

Implied usage is checking login status, but no explicit guidance on when to use vs. alternatives like consent_status or provider_status.

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