CoaCoA (v0.1.0b2.post2) — Context aware Coding Assitant

Context-Optimised Agentic Coding Assistant

• “Drop it in, branch out, ship confidently.”

---

📌 TL;DR

1. pip install --pre coacoa (you can also directly copy the coacoa/ folder, after git clone <repo> if you prefer.)
   (--pre flag is required because this is a beta version)

⚠️ Note: CoaCoA is currently in public beta (0.1.0b2.post2).
To install, use the --pre flag with pip as shown above.
The stable release (0.1.0) will follow soon.

2. coacoa init (or manual copy) — scaffolds coacoa/, CLAUDE.md, .clinerules

3. git add . && git commit -m "init coa"

4. In your IDE (Claude Code / Cline):

   /analyze-codebase        # brown-field   │  or  │  /analyst init      # green-field
   /pm new-prd
   /ux-designer make-ui
   /po refine-epics
   /architect finalize-arch
   /scrum-master create
   /orchestrator run        # Dev → QA loop
   

5. Review staged branch feature/s_001_01, commit & push.

6. Rinse, repeat → production-ready PRs with ≥ 90 % test coverage and zero broken builds.

🏃‍♂️ CLI quick-start

Virtual-env: Create virtualenv .venv at the project root python3 -m venv .venv
All build, test, and lint commands run inside that venv, keeping global Python untouched.

# run with explicit sub-command
coacoa init --claude-code            # scaffold + create CLAUDE.md

# or simply run without a sub-command (same as `init`)
coacoa --claude-code

Getting help

Command	Shows…
coacoa --help	Global options and the list of sub-commands (init, version, …)
coacoa init --help	The per-command flags: --claude-code, --cline

-Tip – Running coacoa with no arguments is equivalent to coacoa init, so you can type the shorter form once you’re familiar with the flags.

🔧 Configuration

• Default settings live in .coacoa/coacoa.yaml (ignored by Git).
• Create coacoa.yaml at project root to override any key; values deep-merge on top of the defaults.

✨ Why CoaCoA?

Area	CoaCoA v0.1
Config schema	28-key namespaced YAML
Code-intel	map + deps + complexity + hotspots + coverage + cycles + build_info
Quality gates	🎯 5 checklists (Anti-Hallucination, Link, QA, Arch, Build)
Workflow	12 agents (UX, PO, Architect, Code-Explorer, Orchestrator)
Branching	auto feature/ branch (staged, not committed)
SOLID policy	Pragmatic SRP/OCP mandatory, rest advisory via ADR

🗂 Folder & file map

coacoa/
├─ coacoa.yaml ← config (paths, limits, workflows…)
├─ agents/ ← markdown specs (analyst, pm, … orchestrator)
├─ tasks/ ← step-by-step recipes (analyze_codebase.md …)
├─ templates/ ← PRD, UI/UX, architecture, story, ADR…
├─ quality/ ← checklists (anti_hallucination, build_integrity…)
├─ data/ ← tech_preferences.md, solid_policy.md, style_guides/
├─ workflows/ ← default_greenfield.yml, default_brownfield.yml
└─ context/ ← generated intelligence artefacts

Git Add coacoa/* to .gitignore.
Orchestrator stages changes; you commit/push.

💬 Command palette (Claude Code / Cline)

Slash command	Agent invoked	When you use it
/analyze-codebase	Code-Explorer	First step in brown-field repo
/analyst init	Analyst	First step in green-field idea
/pm new-prd	PM	Generate / refresh PRD
/ux-designer make-ui	UX-Designer	Add UI flows & a11y notes
/po refine-epics	Product Owner	Rank epics, create backlog
/architect finalize-arch	Architect	Produce architecture doc & ADRs
/scrum-master create	Scrum-Master	Split epics into stories
/dev implement	Developer	Work a single story
/qa review	QA	Validate Dev’s story
/orchestrator run	Orchestrator	Drive Dev → QA for next story

(Run /orchestrator log anytime to see pipeline status.)

🚀 Green-field walk-through (idea → app)

/analyst init    "Real-time expense tracker for remote teams"
/analyst         # responds with clarifying questions
→  You answer those questions until ✔ Open-Questions list is empty

/pm new-prd
    ↳ prd.md + initial epics e_001.md … e_n.md
/ux-designer make-ui
    ↳ ui_ux.md with wireframes + a11y notes
/po refine-epics
    ↳ backlog.md (ranked)
/architect finalize-arch
    ↳ architecture.md + docs/adr/2025-07-26-db-choice.md
/scrum-master create
    ↳ stories/s_001_01.md …
/orchestrator run
    ⇒ feature/s_001_01 branch staged
    ⇒ Dev builds, tests (≥ 90 % coverage), updates story footer
    ⇒ QA validates, appends report
Human: git commit -m "story s_001_01 – user onboarding" && git push

Notes

• "/analyst init "<one-sentence product idea>" – You can supply a single-line vision statement inline, or just run /analyst init and paste whatever raw notes you have.
• The Analyst will always ask follow-up questions until its Open-Questions list is empty; that guarantees the PM starts with a complete domain doc.
• Everything after the Analyst step remains identical to the original workflow.

🔧 Brown-field quick-start

git clone <legacy-repo>
cp -r coacoa/ CLAUDE.md .clinerules .
echo "coacoa/" >> .gitignore
/analyze-codebase         # CIS artefacts + build_info.json
/pm new-prd               # aligns PRD with real modules
/po refine-epics
/architect finalize-arch  # breaks cycles, writes ADR
/scrum-master create
/orchestrator run

Branch rule
Each story = its own branch feature/s_ staged only. Humans merge to
trunk after review → zero surprise refactors.

✅ Quality gates snapshot

• Build-Integrity – build, test, lint run before QA (B-1…B-5).
• Coverage – ≥ 90 % lines for touched files; delta tracked in story footer.
• Anti-Hallucination – 12-point symbol & path sanity.
• Arch-Integrity – no dependency cycles, ADRs linked.
• SOLID (pragmatic) – SRP & OCP hard-enforced; others advisory via ADR.

🧑‍🎓 Extending CoaCoA

• Add a new agent: drop agents/.md, reference it in a workflow YAML.
• Add a new quality gate: create checklist in quality/, list it under agent’s checks:.
• Swap LLM: change llm.default in coacoa.yaml.

🤔 FAQ

Q: Why no auto-commit?
A: Corporate compliance often requires human sign-off; CoaCoA stages but never commits.

Q: Will stories bloat token context over time?
A: Micro-context is capped to max_snippet_loc (120 LOC); old modules are referenced by path, not pasted.

Q: Can I lower coverage?
A: Yes—set quality.target_coverage in a future release, but 90 % is the sane default for v0.1.
