execution_journal_finish

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

No annotations are provided, so the description must carry the burden. It discloses the return shape ('JSON string with StructuredResult and final journal stats') and enumerates the allowed status values, but it doesn't state side effects such as whether the journal becomes read-only after finishing or what happens if it's already closed. This is moderate transparency for a lifecycle-ending operation.

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 compact and well-organized: a one-sentence summary, Args, Returns, KB pointer, and example. Each section serves a distinct purpose, and the primary action is front-loaded before any detail.

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 every parameter, the return format, includes a KB reference, and provides an example, making it nearly complete for a 5-parameter tool with no annotations. It omits edge-case behavior (e.g., finishing a non-existent or already-finished journal) and detailed constraints on artifacts/verification content, but those are minor 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 description coverage is 0%, yet the Args block documents all five parameters with meanings, allowed status values, optionality, and the example shows realistic usage. This fully compensates for the schema's silence and adds value beyond the raw property types.

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 opens with a specific verb+resource: 'Finish an execution journal and record final evidence.' This clearly distinguishes it from sibling lifecycle tools such as execution_journal_start and execution_journal_log by naming the terminal action.

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 Args section says journal_path is 'Path returned by execution_journal_start', which implicitly tells the agent this tool is the completion step after starting a journal. It doesn't explicitly state exclusions or alternatives, but the workflow context is clear from the sibling naming and the required-path instruction.

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