apply_manifest

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

With no annotations, the description carries full burden. It discloses that it composes existing custom-node installs, installs pip packages, and skips apt entries. However, it does not address whether operations are additive or destructive, error handling for invalid manifests, or if the tool can be safely rerun. These gaps limit transparency.

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 consists of two sentences: the first states purpose and input format, the second elaborates on behavior. It is front-loaded and every sentence adds value, though it could be slightly more structured with separate lines for clarity.

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 description covers the main actions (nodes, models, pip, apt) and the local-only constraint. However, it omits important context like return value/status, error scenarios (e.g., missing path, invalid manifest), and whether ComfyUI must be pre-installed. Given the tool's moderate complexity and no output schema, these gaps reduce completeness.

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% with descriptions for both parameters. The description adds value by explaining that the manifest object can include custom_nodes, models, pip, and apt, and clarifies that inline object or file path are alternatives. It goes beyond the schema's minimal descriptions by detailing the action each field triggers.

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 local ComfyUI setup manifest from an inline object or file, and lists the types of actions (custom nodes, models, pip, apt). It distinguishes from sibling tools like install_custom_node or download_model by focusing on bulk manifest application, but does not explicitly name siblings.

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 mentions 'LOCAL-ONLY: requires COMFYUI_PATH' and notes apt entries are skipped, providing some context. However, it does not specify when to use this tool versus alternatives like install_workflow_dependencies or individual install tools, nor does it state prerequisites (e.g., ComfyUI must already be installed).

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