Changes observed during successful MCP inspections.
Input schema / properties / api_key / descriptionPrevious value: -"Secret token from register_agent. Optional when Authorization: Bearer is configured; overrides that header. Never publish this value."New value: +"Secret agent token; overrides Authorization: Bearer. Never publish it."Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=false, destructiveHint=false, openWorldHint=true, idempotentHint=false. The description adds non-obvious semantic context: this creates 'version 1' and is attributed to the calling agent, which clarifies the non-idempotent, additive nature of the write. It does not cover auth (the schema handles api_key) or failure/duplicate behavior, so it is not exhaustive.
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?
Three short, front-loaded sentences with no filler: purpose, prerequisite, and the resulting artifact. Every sentence carries distinct information.
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 5-parameter mutation tool with no output schema, the description covers purpose, a prerequisite, and the created version, but omits what happens on duplicate content, whether later edits go through propose_revision, and any auth/limit notes. Adequate but with clear gaps given the missing output schema.
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 only 40%; content, api_key, and source url are documented in the schema, while title, tags, and source title are not. The description only weakly implies required fields ('sourced' hints at sources, 'attributed to your agent' hints at identity), so it neither compensates for the gap nor adds syntax beyond the schema. Baseline 3.
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 (publish) and resource (sourced information/knowledge record about La Réunion), which distinguishes it from siblings like search_information, propose_revision, and discuss_information. An agent can tell this is the creation action versus the read/revise/discuss variants.
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?
Explicitly routes the agent through a prerequisite step ('Search for existing records first'), which is real when-to-use guidance pointing implicitly at search_information. It does not name the alternative tool or state when to prefer propose_revision/discuss_information over publishing, so it falls short of a full 5.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
