Project Init

Run this workflow only for greenfield initialization.

  1. Mode Guard

Before interviewing, check:

  • If both docs/architecture.md and docs/plans.md exist, stop and switch to project-update .

  • If docs are missing but code roots/manifests exist (src/ , app/ , apps/*/src , package.json , etc.), stop and switch to project-convert .

  • Continue only when docs are missing and codebase signals are absent.

  1. Interactive Interview

Collect requirements before generating any docs:

  • Ask project name and core goals.

  • Run one market snapshot (similar products, patterns to reuse/avoid).

  • Draft project intro + end-to-end core flow and confirm with the user.

  • Propose 3-4 architecture + visual directions; get user choice.

  • Run clarifying rounds (user journeys, components, stack, deployment, constraints).

  • Assign complexity tier (Standard by default; Complex only when justified) and confirm.

  • Provide final synthesis; require explicit user approval before writing files.

  1. Generate Documentation

After user confirmation, create/update:

  • docs/architecture.md

  • docs/plans.md

  • docs/implement.md

  • docs/secrets.md

  • docs/documentation.md

  • docs/design.md

  • docs/decisions.md (for Standard/Complex tiers)

  • tasks/todo.md

  • tasks/lessons.md

  • CLAUDE.md

  • AGENTS.md

Rules:

  • Keep docs/architecture.md as the stable product/technical source of truth.

  • Keep docs/plans.md milestone-driven and ensure Production Readiness Gate is the final milestone.

  • Keep docs consistent with each other; never leave unresolved contradictions.

  • In docs/implement.md , add mandatory sections:

  • First-Principles Execution

  • Atomic Task Execution

  • Rewrite-First Policy

  • No-Compatibility Rule

  • In docs/plans.md , every task must include Commit Boundary: exactly one atomic commit .

  • In tasks/todo.md , every task must include Task ID and Commit Status (pending or done ).

3.5. Implementation Discipline (Mandatory)

Apply these rules to every implementation task generated by this workflow:

  • Use first-principles execution: solve root causes from requirements and architecture, not superficial patches.

  • Treat task and sub-task as the same execution unit.

  • Enforce one task -> one atomic commit .

  • Finish the full task scope before commit: all affected code, tests, configs, scripts, and docs.

  • Follow code is cheap : if a module becomes hard to fix cleanly, delete and rewrite the module.

  • Do not add compatibility code (adapter , shim , dual-path logic, deprecated aliases, temporary compatibility flags).

  • If a rewrite changes interfaces, fix all impacted callers in the same task.

  • Do not leave breakage for a follow-up task just to preserve compatibility.

  1. Review Protocol

Run all review gates before handoff:

  • Tier review:

  • Standard: Agent 2 + Agent 3

  • Complex: Agent 1 + Agent 2 + Agent 3

  • Mandatory cross-model review via mcp__codex__codex on docs/architecture.md

  • docs/plans.md .
  • Apply valid findings and re-check consistency.

  • Ask user for one annotation pass on docs/architecture.md and docs/plans.md , resolve notes, and wait for explicit "ready".

If mcp__codex__codex is unavailable, do not skip silently. Ask user to choose manual checklist path or alternate-model path and record which was used.

  1. Hooks Installation (Mandatory)

Before final messaging, auto-install hooks:

  • Detect package manager:

  • bun.lock -> bun

  • pnpm-lock.yaml -> pnpm

  • yarn.lock -> yarn

  • otherwise npm

  • Resolve installer path in this order:

  • scripts/setup-hooks.sh

  • ../full-project-skill/scripts/setup-hooks.sh

  • Run:

bash <resolved-setup-hooks-path> --pm <detected-pm> --project-dir <project-dir> --platform both

  • If no installer path exists, ask the user where their hook installer lives and stop.

  • If installation fails, show the error and stop for user resolution.

  1. Final Handoff

Tell the user:

  • Docs are ready under docs/ .

  • Hooks are installed to .claude/ and .codex/ .

  • They should review docs/architecture.md

  • docs/plans.md .
  • Execution should follow docs/implement.md .

  • Work is complete only after passing the Production Readiness Gate milestone.
