codespace_release

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

With destructiveHint=false and openWorldHint=true declared, the description still adds real behavioral context beyond the annotations: the grace-period skip, the dedicated-instance-only constraint, that holds keep the instance running for debugging, and that storage is retained. It stops short of stating whether the codespace itself is destroyed or how long a release takes to take effect.

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?

Purpose is front-loaded in the first clause, then each action is labeled and described in one compact segment. No filler sentences, though the run-on density makes it slightly harder to scan than a bulleted form.

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?

The output schema exists, so listing the status record fields (state, blockers, computeRelease, storageRelease, exportStatus) is mildly redundant but harmless. For a mutating, multi-action tool with zero annotation detail on side effects and completely undocumented secondary parameters, the description leaves meaningful gaps around holdId and hold duration.

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 0% across 5 parameters, so the description carries the full burden. It explains the action enum's semantics well, but holdId (needed for unhold), holdSeconds (its 60–14400 range is only vaguely hinted at by 'bounded'), locale, and projectId are entirely undocumented anywhere.

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 names a specific resource ('the bound Codespace') and a lifecycle operation, then breaks the polymorphic action parameter into its four variants (status/request/hold/unhold). An agent can tell what this tool does and which action to pick, though it never contrasts itself with siblings like codespace_prepare or project_bind.

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?

Each action carries a use condition: 'request' applies 'as soon as no job, hold or unconfirmed submission remains (skips the grace period; dedicated only)', 'hold/unhold' is for debugging, 'status' reads the release record. That is genuinely actionable when-to-use guidance per variant, but there is no guidance on when this tool is preferable to its siblings.

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