apply_manifest

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

With no annotations, the description carries the burden and fairly discloses key behaviors: it composes existing installs (implies non-destructive), installs pip packages, and skips apt entries. It also mentions local-only dependency. Missing details on idempotency or error handling, but sufficient for most agents.

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 description is concise (two sentences) but packs relevant info. Front-loads the action and constraints. Could be slightly more structured (e.g., list constraints), but no wasted words.

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 tool with nested parameters, no output schema, and a large sibling set, the description covers the main behavior and a key limitation (apt skip). However, it lacks detail on return values, error scenarios, and whether the tool updates or overwrites existing installations. Adequate but with gaps.

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 coverage is 100%, so baseline is 3. The description adds value by explaining the mutual exclusivity of manifest and path, and by summarizing what the manifest object contains (custom_nodes, models, pip, apt). This provides meaning beyond the raw schema.

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 the tool applies a ComfyUI setup manifest, specifying the verb 'apply' and resource 'manifest'. It distinguishes from many sibling tools by focusing on manifest application, a unique operation in the list.

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?

The description clearly states the tool is local-only and requires COMFYUI_PATH, giving context for when to use it. It explains what it does (auto-installs custom nodes, models, pip packages) and notes that apt entries are skipped, but does not explicitly compare to alternatives or mention when not to use it.

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