Get a second opinion from GitHub Copilot CLI on a plan or approach. Use when: (1) Planning phase of /x-as-pr or /x-wt-teams to validate the approach, (2) User says 'gco 2nd', 'copilot 2nd', or 'copilot opinion', (3) Wanting an alternative perspective before committing to a plan.

Sweep open GitHub issues — optionally narrowed by label — and drive each to completion via `/big-plan -m -a`. Collects candidates, triages out work that needs careful human judgment, confirms once, then handles the rest autonomously one issue at a time. Use when: (1) User says '/issue-sweep', 'sweep issues', 'sweep open issues', 'handle the open issues', 'clear the issue backlog', or 'do the issues', (2) The user wants to batch-process a label's worth of issues (e.g. `agent-found`, `mac`), (3) After a work round that left a pile of follow-up issues. Options: "`-f`/`--filter LABEL` keeps only issues carrying that label; `-ex`/`--exclude LABEL`" drops issues carrying it; with no options it sweeps ALL open issues. Locally-checkable "verify X" tasks are verified directly and closed (not run through `/big-plan`). Skips issues that need careful human judgment (huge multi-major version bumps, super-big epics, design calls); verification tasks that can't be auto-verified locally (auth/deploy/external/subjective) are
Generate or redesign raster images (PNG mockups, illustrations, photos, UI design polish) from inside Claude Code by driving Codex CLI's built-in $imagegen, billed to ChatGPT-included usage instead of per-image OpenAI API charges. Use whenever the user wants to create/generate an image, make a mockup or illustration, produce a photo, polish or redesign a UI from a screenshot, or get a PNG out of a session — even if they don't mention Codex or "imagegen". This is the preferred image-generation path because Anthropic models cannot generate raster images and this route avoids API billing.
Iterative visual design-polish loop for an existing or WIP web UI. Each round: capture the live page as screenshots, judge it from the rendered pixels, and apply CSS polish toward a better-looking target using /css-wisdom's tight-token strategy — then re-capture and compare. The target direction is set by codex-imagegen 'north-star' mockups generated from the current screenshot, so the loop pursues a genuinely better look instead of nudging the existing one in place. Use when: (1) user says 'design-polish-loop', 'polish loop', 'polish this page/design/UI', (2) user wants to level up / upgrade the look of a current design or WIP project, (3) user wants AI-proposed redesign directions applied to a real rendering page, (4) user calls a design plain, dated, flat, or unpolished and wants it improved. Main use case: improving the current design of a WIP project. It polishes what already renders — not brand-new-from-scratch pages.
Bump every `@takazudo/*` registry dependency in the current project to its newest version, resolving each by the channel it currently tracks. Use when: (1) User says '/dev-bump-zudo-deps', 'bump zudo deps', 'bump the @takazudo packages', 'update zfb', 'update zudo-doc', or 'update the takazudo toolchain to latest', (2) A new `@takazudo/*` prerelease or release has shipped and this project should adopt it, (3) Routine first-party dependency-update rounds. Resolution rule: a dep currently on the `next` prerelease line (`0.1.0-next.N`) → newest `next` release; a dep on the literal `latest` tag → `dist-tags.latest`; a plain stable semver → newest stable. Skips `workspace:`/`file:`/`link:` specs and leaves operator style (exact / `^` / `~`) and prerelease channel intact. A bundled script does the discovery + semver resolution; this skill drives install + verify + report.
Plan implementation by breaking work into one epic GitHub issue + child sub-issues. Use when: (1) User says '/big-plan', (2) User wants to plan an implementation before coding, (3) User wants to split a feature into small issues for parallel agent team work, (4) User references existing issues (e.g. 'implement issue #123', 'plan all open issues', 'plan recent 3 open issues'). Auto-reads project-scope l-lessons-* skills (from /retro-notes) before planning. Codex (-co) is the DEFAULT Step 5 plan reviewer — it runs even when no reviewer flag is passed; -op/-gco add more second opinions (runnable in parallel). Use -a/--auto to run the chain autonomously: skip the Step 6 confirmation wait (pausing only when something needs careful consideration), auto-create the issues, then auto-invoke the implementation skill in the same session — /x-wt-teams for a multi-sub-issue plan, /x-as-pr for a single-sub-issue plan — forwarding -a so multi-wave plans auto-chain wave after wave. Use -m/--merge to also merge the final PR i
Purge GitHub Actions caches across every non-archived repo for one or more GitHub owners (users or orgs). Use when (1) the user says "purge gh cache", "clear actions cache", "delete CI cache", or invokes /dev-purge-gh-cache, (2) the user wants to free up GitHub Actions cache storage for an account/org, (3) the user names one or more GitHub owners (e.g. "Takazudo", "zudolab") and asks to wipe their Actions caches. Handles fan-out across all repos, parallel survey, bulk delete, and real-time verification.

Get a second opinion from GitHub Copilot CLI on a plan, approach, or codebase exploration.
Before doing anything, check if Copilot is currently in degraded mode:
RATE_CHECK=$(node $HOME/.claude/scripts/gco-rate-limit.js check 2>&1)
If the output starts with degraded:, notify the user that Copilot is in low-cost mode (auto-downgraded model) but proceed with Copilot anyway — it is still usable. Do NOT skip.
Construct a prompt that includes:
You are reviewing a development plan. Provide a second opinion.
## Context
<what the project is, what repo we're in>
## Current Plan
<the plan or approach being considered>
## Questions
1. Are there any risks, edge cases, or issues with this approach?
2. Is there a simpler or better alternative?
3. Are there any files or areas of the codebase that should be considered but aren't mentioned?
4. Any other suggestions or concerns?
Be concise and practical. Focus on actionable feedback. If the plan looks solid, say so briefly — don't invent problems.
LOGDIR=$(node $HOME/.claude/scripts/get-logdir.js)
mkdir -p "$LOGDIR"
DATETIME=$(date +%Y%m%d_%H%M%S)
bash $HOME/.claude/skills/gco/scripts/gco-run.sh \
"<prompt>" \
"$LOGDIR/${DATETIME}-gco-2nd.md" \
"$LOGDIR/${DATETIME}-gco-2nd-stderr.log"
Timeout: 15 minutes.
Return the Copilot feedback to the caller. The caller decides whether to incorporate it into the plan.
No fallback needed. If Copilot fails, skip — the plan proceeds without the second opinion. This is advisory, not critical.
