Skill Debug

Debugging

Read skills/blocks/engineering-method-selection.md from the installed plugin for review admission. Natural-language requests and --peer-review share that policy. Honor host-only requests; risk alone does not authorize paid usage.

Run the investigation on the current host. Routine debugging makes zero additional provider dispatches. Use a bounded external reviewer only for --peer-review, an explicit independent-review request, or an existing risk policy.

Read and apply skills/blocks/debug-feedback-loop.md from the installed plugin root.

Start with the user's observable symptom. Reproduce it, retain its failure signature while minimizing the scenario, test one named hypothesis at a time, and verify both the minimal reproduction and the original scenario after the fix. Do not treat a nearby passing helper test as proof.

For a race, use a synchronization barrier and a fixed run or time budget. For an unavailable production dependency, return inconclusive with the missing evidence. Remove temporary instrumentation before completion and preserve a stable reproduction as a regression test.

The final record is data, not an executable queue. Store commands as argument arrays and never evaluate provider-authored text.

Bounded recovery and strategy rotation

Use a 3-Strike Rule for failed fixes. After each failure, return to the evidence and test a materially different hypothesis. After two consecutive failures, a strategy rotation is mandatory: reconsider the root cause, the reproduction, and whether the test encodes the intended behavior. Do not attempt a 4th fix without explicit user approval.

Anti-rationalization check: “Should work now” means run the reproduction and the original scenario. Confidence is not verification.

For multi-attempt debugging, report a WTF score using the defaults in ~/.claude-octopus/loop-config.conf: +15% per revert and +20% for touching unrelated files. If the score exceeds 20%, STOP and show the evidence before continuing. Include the score with every retry, for example:

Fix attempt 2 | Self-regulation: 15% (1 revert, 0 unrelated files)

Scoped freeze guard

When the symptom is localized to one user-approved module, resolve that module to a physical directory before editing and activate the existing freeze guard:

freeze_dir="$(cd "<module-directory>" 2>/dev/null && pwd -P)" || exit 1
printf '%s\n' "$freeze_dir" > "/tmp/octopus-freeze-${CLAUDE_SESSION_ID:-$$}.txt"

Do not auto-freeze when the root cause is still unknown, the reproduction spans modules, or the user opted out. After original-scenario verification, run /octo:unfreeze or remove only this workflow's freeze state.
