false-alarm-detection

Classify a test failure as a known infrastructure false alarm rather than a genuine test bug, by comparing the log against pluggable pattern definitions. Loads false-alarm-detection-context.json (test metadata) and the raw test.log, then reads every pattern file under ${CLAUDE_SKILL_DIR}/patterns/ -- each describing key signals, an example log excerpt, and explicit "what this is NOT" exclusions (e.g. container_pull_failure, where the container runtime cannot pull the base image and the test never runs). Focusing on the actual error and ignoring post-failure cleanup, it decides whether the failure is caused by the infrastructure problem a pattern describes (a false alarm) or by a real bug. The verdict records matched_pattern (a pattern filename without the .md extension, or JSON null) and a one-sentence reasoning, schema- and semantically-validated (the semantic check confirms the named pattern exists on disk) and repaired until it passes. New false alarms are added simply by dropping in a new pattern file -- no code changes.

Determine whether a test failure log shows a known infrastructure problem (a false alarm) rather than a genuine test bug by comparing the log against pattern definitions shipped with the skill.

Identity

Functions

analyze

Success

• Produces /workspace/verdict.json with matched_pattern and reasoning fields.
• matched_pattern is either a valid pattern name corresponding to a file in patterns/ or JSON null.
• verdict.json passes JSON Schema validation and semantic validation confirming the pattern exists on disk.

Must Preserve

• Do not modify the test log or pattern files.

Usage

# Invoked by the AutoQA orchestrator inside the agentic-ci runner (internal skill)
# Inputs:  /workspace/_context/false-alarm-detection-context.json  +  /workspace/_context/test.log  +  patterns/*.md
# Output:  /workspace/verdict.json  { matched_pattern, reasoning }
