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

Far exceeds the annotations (readOnlyHint=false, destructiveHint=false) by describing the full lifecycle: files are imported, diffed against the live version, and only changed files submit a new version for review with an auto-drafted changelog while the live version keeps serving until approval. It also states that unchanged files are a no-op and that GitHub-sourced agents are refused.

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?

The core operation and its non-obvious lifecycle are front-loaded clearly, but the definition is a single dense paragraph with many embedded parentheticals and a long trailing routing section that is only tangentially about reupload. Most sentences earn their place, though the routing block is heavier than this tool's own needs.

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?

An output schema exists so return values need not be explained; the description covers ownership/auth, upload-vs-import preconditions, diff-and-review behavior, and the github_source refusal. For a 4-param mutation with nested files, nothing an agent needs to call it correctly is missing.

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?

With 100% schema coverage the baseline is 3, but the description adds real meaning: files is cross-referenced to findagent_create_package_draft's format and 'same skill rules and caps', attestation's required value and rationale (confirms own work), and bump's default (patch). This goes beyond the schema text without fully re-specifying parameter syntax.

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 and resource — publish a NEW version of your own published, uploaded skills agent — with sharp scope qualifiers ('UPLOADED (not imported from GitHub)'). It explicitly names the sibling it is not for (findagent_repull) and the error surfaced (github_source), so an agent can distinguish it from repo-based versioning without opening a schema.

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 explicit when-to-use (own, uploaded, attested files) and when-not (GitHub-imported agents, which must use findagent_repull), plus the required precondition attestation='own-work'. The trailing 'which tool for which part' block routes the agent among create_package_draft, create_code_draft, create_remote_mcp/local_mcp, import_openapi, and import_repo.

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