Challenge

Standalone adversarial spec review. Runs the full challenger analysis on an existing grooming spec and outputs a verdict (APPROVED / NEEDS_REVISION / BLOCKED) with MoSCoW-classified findings. Posting to the GitHub issue is your choice — you are prompted at the end.

Step 1 — Locate files

This skill targets wp-media/wp-rocket. Use $ARGUMENTS as the issue number N. Verify both files exist:

• Issue file: .TemporaryItems/Issues/wp-rocket/issues/<N>.md
• Spec file: .TemporaryItems/Issues/wp-rocket/issues/<N>-spec.md

If the spec does not exist, tell the user: "No spec found for issue #N. Run /groom <N> first to produce one." Stop here.

If only the issue file is missing, sync it:

bash .claude/skills/issue-workflow/scripts/issue-sync.sh <N>

Step 2 — Invoke the challenger agent

Invoke the challenger sub-agent with:

• Issue number N
• Issue file path: .TemporaryItems/Issues/wp-rocket/issues/<N>.md
• Spec file path: .TemporaryItems/Issues/wp-rocket/issues/<N>-spec.md
• plan_version: 1 (or detect from the spec's Plan v<N> header if present)
• CURRENT_MODEL: "standalone"
• session_learnings: read Section 13 of AGENTS.md if it exists, else pass empty string
• Repo: wp-media/wp-rocket

STANDALONE MODE — one difference from the normal pipeline run: Skip the StructuredOutput JSON return. Output the full human-readable verdict (APPROVED / NEEDS_REVISION / BLOCKED) and findings in a section titled ## Challenge Report, using the same format the orchestrator would receive (verdict, MoSCoW-classified findings, alternative suggestions).

Step 3 — Offer to post

After the agent responds, display its ## Challenge Report and ask:

Post this challenge report as a comment on issue #<N>? Reply yes to post, no to finish here.

If yes — post with dedup:

EXISTING_ID=$(gh api repos/wp-media/wp-rocket/issues/<N>/comments \
  --jq '[.[] | select(.body | contains("<!-- ai-pipeline:challenge -->"))] | last | .id // empty')

Update with gh api --method PATCH repos/wp-media/wp-rocket/issues/comments/$EXISTING_ID if found, otherwise post a new comment. Body always starts with <!-- ai-pipeline:challenge -->.

If no — finish. Remind the user: if the verdict is NEEDS_REVISION, update the spec at .TemporaryItems/Issues/wp-rocket/issues/<N>-spec.md before running /groom <N> again or starting implementation.
