record_bond_outcome

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

With no annotations, the description carries the full burden. It does add genuine behavioral context: this is a persistent write feeding a learning loop ('so Kiln learns over time') and it is gated behind Kiln Pro. However it never states what happens on a non-Pro call, whether repeat submissions for the same design are deduplicated, or what a successful call returns.

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 first sentence is well-formed and front-loaded, but two of the four remaining lines are marketing copy and an upgrade URL that do not help invoke the tool. The upsell is disproportionate to the one sentence of real substance.

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 9-parameter write tool with no annotations and no output schema, the description says nothing about the parameters, the accepted result values, the feedback loop's outputs, or error behavior. It is far short of what an agent needs to call this correctly.

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?

Nine parameters with only 67% schema coverage, and the coverage that exists is inert boilerplate ('Default: ""'). The description names no parameter at all, and critically leaves 'result' — the most important field — with no enum or accepted values, so an agent cannot know whether to pass 'held', 'failed', or something else.

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 opening sentence gives a specific verb and resource — record whether a glued joint held or failed — which is concrete enough to act on. It does not distinguish itself from near-identical siblings such as record_hardware_outcome, record_load_outcome, record_magnet_outcome, or record_chemical_outcome, so the agent gets no help choosing among them.

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 only usage guidance is the prerequisite 'Requires Kiln Pro', which is a gating note rather than when-to-use guidance. Nothing says when to call this versus recommend_adhesive, recommend_joint_strategy, or get_joint_recommendation, nor how often to log an outcome.

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