create_report

Idempotent

Publish an authored narrative report to Reports. Provide a distinct title, summary, and prose body; paragraphs are preserved. Exclude secrets and source dumps.

Input Schema

TableJSON Schema

Name	Required	Description
`body`	Yes

TDQS

B3.4/5.0

Behavior3/5

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

Annotations already declare the safety profile (not read-only, idempotent, not destructive, closed-world), so the burden is lower. The description adds two genuinely behavioral facts: paragraph preservation in the prose body and a content restriction against secrets/source dumps. It does not explain what publishing produces or how the idempotency key interacts with retries.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three short sentences, no filler, with the core action front-loaded and the content constraints following. Every sentence carries information; it could be tighter only by merging the last two clauses.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

This is a complex mutation (9 parameters, nested objects) with no output schema, so the description should carry more weight. It omits any mention of the optional scoped 'outcome' object, attachments, or retry semantics, leaving an agent to discover the tool's richer capabilities from the schema alone. Adequate but with clear gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 56%, so the schema documents some parameters (projectId, idempotencyKey, sessionId, executionId) but the description only names title, summary, and body. It adds no meaning beyond those three field names and leaves the complex nested 'outcome' scope/criteria/evidence structure entirely to the schema. This compensates only partially for the coverage gap.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource: 'Publish an authored narrative report to Reports.' The phrase 'authored narrative report' distinguishes it from read/write siblings like get_report, list_reports, and update_report, though it never explicitly names any alternative. Clear purpose, but sibling differentiation is left implicit.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives content guidance ('Provide a distinct title, summary, and prose body', 'Exclude secrets and source dumps') but never states when to use this versus alternatives such as queue_report, create_report_bug, or update_report. The usage context is implied rather than explicit, and no prerequisites or exclusions are given.

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