GitHub GStack Intelligence ships twenty-six AI skills that run as GitHub Actions workflows. Each skill is an AI specialist triggered by GitHub events — pull requests, issue comments, labels, releases, schedules, and deployments.
This directory is the single source of truth for command documentation. Click any command below to see the full reference.
Root cause investigation following the Iron Law: "no fixes without root cause investigation first." Four-phase methodology with scope lock and a 3-strike rule.
Systematically tests a web app like a real user — clicks everything, fills forms, checks states — finds bugs, then iteratively fixes them with atomic commits and re-verifies.
Designer's-eye QA that finds visual inconsistency, spacing issues, hierarchy problems, and AI slop patterns — then fixes them iteratively with before/after screenshots.
Proposes a complete design system — aesthetic, typography, color palette, layout grid, spacing scale, and motion principles. Creates a DESIGN.md as the project's design source of truth.
Design finalization — generates production-quality HTML/CSS from approved mockups, CEO plans, or design review context. Dynamic layouts, real reflow, zero dependencies.
Design exploration — generates multiple AI design variants, opens a comparison board, collects structured feedback, and iterates. Visual brainstorming for any UI feature.
One-command, fully-reviewed plan. Runs CEO, design, and engineering reviews sequentially with auto-decisions. Surfaces taste decisions at a final approval gate.
Live developer experience audit — navigates docs, tries the getting started flow, times TTHW, screenshots error messages, evaluates CLI help text. Produces a DX scorecard with evidence.
Land and deploy workflow — merges the PR, waits for CI and deploy, verifies production health via canary checks. Takes over after /ship creates the PR.
Safety guardrails for destructive commands — warns before rm -rf, DROP TABLE, force-push, git reset --hard, and similar operations. Override any warning.
enabled — Set to false to disable a skill without removing its configuration.
trigger — The GitHub event type that activates the skill (pull_request, issue_comment, issue_label, schedule, release, deployment_status).
labelGated / label — For label-gated skills, the skill only triggers when the specified label is present.
schedule — Cron expression for scheduled skills. Must also be registered in the workflow file.
Global defaults (model, cost tier, max comment length) are set in the defaults section of config.json. The AI model is configured in .pi/settings.json.
Skills are gated by repository permissions. Only users with admin, maintain, or write permissions can trigger commands. Bot-loop prevention is enabled by default. See the access section in config.json for details.
