pin_resume

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

With no annotations, the description carries the full burden. It helpfully discloses the default behavior of eid (defaults to the last received event) and the meaning of event-type codes, but says nothing about prerequisites (the process presumably must be paused), side effects, or reversibility of resuming execution.

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?

Two tightly packed sentences with the verb front-loaded and the default-parameter note following. No wasted words; the only mild deduction is that the parenthetical event-code list slightly burdens the second sentence.

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 one-parameter command with no output schema and no annotations, the description covers the parameter default and event codes but omits the operational state required to call it (must be stopped at an event). It is adequate but leaves a real gap for correct invocation.

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%, so a baseline of 3 applies, but the description goes beyond the schema by enumerating what the eid values mean (PROCESS_STARTED=1, BREAKPOINT=5, STEP=6), which is not present in the parameter definition itself.

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 specific verb ('Resume') and the trigger context ('after an event'), which is enough to distinguish it from the opposite action pin_pause and from pin_step. However it never names a sibling, so the differentiation relies on the agent inferring the pause/resume pairing.

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 phrase 'after an event' implies this is used to continue execution once stopped at a breakpoint/step, but there is no explicit when-to-use or when-not-to-use guidance and no reference to pin_pause, pin_step, or pin_stop as alternatives. Usage is only inferable from context.

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