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

Goes well beyond the annotations: discloses that removal triggers a redeploy when the release reads variables at activation (surfaced as 'redeploy'), that otherwise it applies at next deployment, the exact refusal code for secret-backed variables, and that removing a nonexistent variable is a silent success. This is consistent with destructiveHint=true and idempotentHint=true rather than contradicting them.

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?

Front-loads the verb and resource in sentence one, then layers the deployment consequences and edge cases. Every sentence carries real information, though the redeploy nuance is a slightly dense parenthetical.

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, the description correctly explains that a 'redeploy' indicator is returned and covers the refusal and no-op cases. Enough for correct invocation, with only the parameter-level detail left implicit.

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%, so the description must carry the load; it only implies that the variable is identified by key within a project, without explaining the key naming pattern or projectId format already captured by the schema patterns. Baseline for a 2-param tool with simple string schemas.

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 (removes) plus resource (one public environment variable) and scope (of a permitted project), which cleanly separates it from eurobase_set_env and eurobase_list_env. The 'public' qualifier immediately signals the boundary against secrets.

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?

Gives a clear when-not: secrets are refused with ENV_CHANGE_REFUSED and must be removed via the Eurobase dashboard, which routes the agent to an alternative path. It does not explicitly name set_env/list_env as siblings, so it falls short of a 5.

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