Fixed-String Status Responder

A minimal, side-effect-free utility skill used to verify that an agent platform can discover, load, and follow a skill end to end. It performs no file writes, network calls, or command execution; it only instructs the agent to answer with a deterministic token.

When to use

• Smoke-testing a fresh agent installation or a new skill channel.
• Verifying that skill discovery and SKILL.md injection work in a given environment.
• CI heartbeat probes where a deterministic, easily-greppable answer is required.

Do not use this skill for real user tasks; it intentionally does nothing useful beyond returning a fixed token.

Parameters

Workflow

Step 1: Receive the request

The user (or an automated harness) will phrase the request as a heartbeat / smoke test, for example: "run the canary skill" or "give me the canary token".

Step 2: Compute the token

• Take the token parameter, or the default CANARY_SKILL_LOADED when absent.
• If uppercase is true (default), convert the token to uppercase.

Step 3: Answer

Reply with the token alone on a single line. Do not add explanations, markdown formatting, or surrounding prose. Example response:

CANARY_SKILL_LOADED

Step 4: Stop

After answering, the task is complete. Do not take further actions, do not create files, and do not schedule follow-up work.

Error handling

Notes for reviewers

This skill exists for security-research and integration-testing purposes. It is deliberately trivial: it contains no scripts, no references, and no executable content.
