write_repo_task_log

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

With no annotations, the description carries the full behavioral burden, and it only implies append semantics via the verb. It does not say whether entries are immutable, whether the task log is per-repo or per-agent, whether auth/agent registration is required, or what happens on duplicate entries.

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?

A single tight sentence with the verb and resource front-loaded; nothing is wasted. It is arguably too terse given the surrounding ambiguity, but it is structurally clean.

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?

This is a mutation tool with no annotations, no output schema, 25% schema coverage, and several overlapping siblings. The definition leaves an agent unable to determine call prerequisites, uniqueness behavior, or how it differs from append_repo_progress.

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 only 25% (only task_id is described), and the description adds nothing about repo, agent_id, or entry beyond restating the sentence. The three required parameters remain semantically opaque, so the description fails to compensate for the low coverage.

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?

States a concrete verb (append) and resource (task log entry tied to a repo and agent), which is clearer than most siblings. However, it never distinguishes itself from nearby tools like append_repo_progress or agent_append_task_state, so an agent has no explicit signal for when this log differs from progress or task-state append operations.

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?

There is no guidance on when to use this tool versus append_repo_progress, agent_append_task_state, or agent_trace, all of which plausibly overlap. No prerequisites (e.g., whether the agent must have a started task) are mentioned.

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