Agenticapps Eu Codex Workflow Setup Codex Agenticapps Workflow

setup-codex-agenticapps-workflow

This skill is the entry point for bootstrapping a fresh project with the codex-workflow scaffolding. It applies the baseline migration (migrations/0000-baseline.md) and any additional migrations that have shipped between scaffolder versions, leaving the project at the current scaffolder version.

When to invoke

User asks to set up the workflow on a project that does not yet have a .codex/workflow-version.txt file. The trigger skill's agentic-apps-workflow does NOT auto-route to setup — setup is an explicit, user-driven act because it modifies project-side files (AGENTS.md, .planning/config.json, .codex/) that the user expects to review.

What this skill does

Stage A — Pre-flight

1. Verify Codex CLI. codex --version must succeed.
2. Verify scaffolder install. Confirm ${CODEX_HOME:-$HOME/.codex}/skills/agentic-apps-workflow/SKILL.md exists. If not, instruct the user to clone codex-workflow and run bash install.sh from its root before retrying.
3. Verify project state.
   • Project must be a git repo (test -d .git).
   • Project must NOT already have .codex/workflow-version.txt. If it does, route the user to $update-codex-agenticapps-workflow and stop.
4. Check optional gates. Run the optional_for detection commands from 0000-baseline.md and record the user's choice for each (e.g. Option A vs Option B install).

Stage B — Gather placeholder values

5. Ask the user the questions in 0000-baseline.md Step 1's placeholder table:

   • Project name
   • Repo URL (autofilled from git remote get-url origin if available; otherwise prompt)
   • Client (internal / external name)
   • Budget tier (free / paid / enterprise)
   • Backend language (Go / Python / TypeScript / Rust / Other)
   • Frontend stack (or "none" if backend-only)
   • Database (or "none")
   • LLM provider (anthropic / openai / google / other / none)

   For optional values, accept defaults if the user says "default" or skips:

   • design-critique quality bar (default 90)
   • impeccable-audit quality bar (default 90)
   • QA viewports (default 1280, 390)
   • DB blocking severity (default Critical, High)

Stage C — Apply the baseline migration

6. Walk migrations/0000-baseline.md step by step. For each step:
   • Run the idempotency check. If it returns 0, log "skipped (already applied)" and continue.
   • Run the pre-condition. If it fails, error out with the pre-condition's specific message.
   • Show the user the apply block. In default-on-confirm interactive mode, dry-run the whole chain first; in --no-confirm mode, apply each step automatically.
   • Apply the patch. For Step 1 (workflow-config.md), substitute placeholders with the values from Stage B.
   • On failure: prompt the user with retry / skip-with-warning / rollback options per the atomicity contract in migrations/README.md.
7. Skip Step 6 (global AGENTS.md additions) if the user picked Option B (per-project install) in Stage A's optional gate detection.

Stage D — Post-checks and commit

8. Run all post-checks from 0000-baseline.md:

   • .codex/workflow-config.md exists and has no unsubstituted {{...}} placeholders
   • .planning/config.json is valid JSON with the expected hook keys
   • AGENTS.md contains the BEGIN: agentic-apps-workflow marker
   • docs/decisions/README.md exists
   • .codex/workflow-version.txt reads 0.1.0

9. Atomic commit. All baseline-migration changes go in a single commit:

   git add .codex/ .planning/ AGENTS.md docs/decisions/
   git commit -m "chore: install codex-workflow v0.1.0"
   

10. Surface follow-ups. Tell the user:

    • The project is now at codex-workflow v0.1.0
    • Next step: run $gsd-discuss-phase 1 to start a planning session for the first phase
    • Future scaffolder updates: run $update-codex-agenticapps-workflow periodically; the skill reads .codex/workflow-version.txt and applies pending migrations

Required evidence (per spec/06)

• .codex/workflow-version.txt exists with content 0.1.0
• .planning/config.json is valid JSON with all hooks keys from the template
• AGENTS.md contains the marker pair <!-- BEGIN: agentic-apps-workflow sections --> ... <!-- END: agentic-apps-workflow sections -->
• docs/decisions/README.md exists
• The atomic commit is on the project's current branch with the expected files staged

Failure modes

• Re-running on an installed project. The pre-flight check catches this; never auto-overwrite. Route to $update-codex-agenticapps-workflow.
• Scaffolder not installed. Surface the install path; do not silently skip steps that depend on the scaffolder.
• Half-applied migration. Per the atomicity contract, prompt user (retry / skip / rollback). Do not auto-rollback without consent — the user may prefer partial-state recovery.
• Forgetting Step 6 distinction. Option A (global) and Option B (per-project) are mutually exclusive for this step. Skip Step 6 cleanly when the user picked Option B.

Notes for the Codex host

• The default $CODEX_HOME is ~/.codex. Migrations use the ${CODEX_HOME:-$HOME/.codex} form so users with a non-default $CODEX_HOME get the same behavior.
• The templates/ directory referenced from migrations lives at ${CODEX_HOME:-$HOME/.codex}/skills/setup-codex-agenticapps-workflow/templates/. install.sh symlinks the scaffolder's top-level templates/ to this path so migrations can cp from a stable location.
• "Project name detection" can also pull from package.json::name, pyproject.toml::project.name, Cargo.toml::package.name — surface those as a prefilled default in the question rather than always asking from scratch.
