name: evanflow-go description: Single entry-point orchestrator for the entire EvanFlow loop. The user says "let's evanflow this", "use evanflow", "evanflow this idea", "run this through evanflow", "implement with evanflow", or any similar phrasing — and you walk the full loop (brainstorm → plan → execute → tdd → iterate → STOP) end-to-end, announcing each step, respecting checkpoints, and stopping where the user retains control. Trigger keywords: "evanflow", "let's evanflow", "use evanflow", "evanflow this".

EvanFlow: Go (Entry-Point Orchestrator)

Single entry point for the EvanFlow workflow. The user gives you an idea or task and asks to "evanflow it" — you take responsibility for walking the whole loop end-to-end, picking the right sub-skill at each step, and respecting checkpoints where the user must stay in control.

You are the conductor; the other evanflow-* skills are the orchestra.

Vocabulary

See evanflow meta-skill for the shared vocabulary (deep modules, deletion test, vertical slice, grill, mockup quick-mode).

When to Use

Trigger phrases (or anything semantically equivalent):

• "let's evanflow this"
• "use evanflow"
• "evanflow this idea"
• "run this through evanflow"
• "implement with evanflow"
• "let's [do X] using evanflow"

SKIP when:

• The user is asking a factual question (no skill needed at all)
• The user wants quick mockups only (the brainstorming skill's mockup quick-mode handles this directly — no full loop needed)
• The user explicitly invoked a specific sub-skill by name (evanflow-debug, etc.) — let them control granularly
• The work is a one-line fix or trivial change — full loop is overkill

The Walk

Phase 0 — Restate and Confirm Scope (one sentence)

Confirm you've understood the idea in your own words, in one sentence. Examples:

"Got it — you want to add an archived flag to messages so cancelled ones drop off the dashboard."

Then ask one calibration question if scope isn't obvious:

"Quick scope check: is this a small targeted change or a feature with multiple components?"

If the user signals quick/small → consider whether a full evanflow loop is overkill. Offer a shortcut: "This sounds small — want me to skip brainstorming/planning and just TDD it directly? Or run the full loop anyway?"

Phase 1 — Brainstorm (always, unless user opts out)

Announce: "Step 1: brainstorming via evanflow-brainstorming."

Invoke evanflow-brainstorming:

• Quick context check (skim relevant files; don't exhaustively explore)
• Scope check (decompose if multi-subsystem)
• Clarifying questions one at a time, multiple-choice when possible
• Propose 2–3 approaches with your recommendation as option (a)
• Embedded grill on the chosen approach
• Present the design in sections; get explicit approval

Mockup quick-mode bypass: if the user originally said "show me mockups" rather than "implement," skip the full loop and produce mockups directly (HTML files, Figma frames, ASCII layouts — whatever the project uses). No spec, no plan, no TDD ceremony.

Checkpoint: before continuing, the user must explicitly approve the design. Not a tacit yes — actual confirmation.

Phase 2 — Plan (if non-trivial)

Announce: "Step 2: writing the plan via evanflow-writing-plans."

If scope is small (one file, one behavior change), skip to Phase 3 with a verbal plan ("I'll write a failing test for X, then minimal impl"). Otherwise:

Invoke evanflow-writing-plans:

• File structure first (name files + responsibilities, deletion test on each)
• Embedded grill on the structure
• Bite-sized tasks
• Step 2.5: parallelization check. If the plan has 3+ independent units sharing a contract, offer evanflow-coder-overseer to the user as the execution path instead of sequential executing-plans. Lay out signals on both sides. User picks.

If the user picks coder-overseer, structure the plan with a per-coder section + cohesion contract upfront.

Checkpoint: before continuing, the user must approve the plan.

Phase 3 — Execute (sequential or parallel)

Announce based on user's pick:

• Sequential: "Step 3: executing the plan via evanflow-executing-plans."
• Parallel: "Step 3: executing in parallel via evanflow-coder-overseer."

Sequential path — invoke evanflow-executing-plans:

• Step 0: parallelization re-check (one more chance to switch paths)
• Critical review of plan
• Set up TaskCreate items
• Task-by-task; each task uses evanflow-tdd for any production code
• Inline verification (typecheck, lint, test for affected workspaces)
• Stop and ask on blockers

Parallel path — invoke evanflow-coder-overseer:

• Author cohesion contract (with named tests + integration tests at touchpoints)
• Decompose into coder tasks (max 5)
• Phase A: spawn coders for RED checkpoint (failing tests only)
• Verify all REDs are clean
• Phase B: spawn coders for vertical-slice GREEN
• Spawn per-coder overseers (use subagent_type: evanflow-overseer if available)
• Spawn integration overseer (runs touchpoint tests)
• Reconcile findings (max 3 rounds)

Inside both paths, every code-writing task goes through evanflow-tdd — it's the discipline running inside the execute harness, not a phase that comes after. Per-cycle: RED → GREEN → REFACTOR (refactor with the fresh test as safety net, not deferred to the end). Behavior through public interface, watch each test fail before writing impl, assertion correctness check.

Phase 4 — Iterate (always, on success)

Announce: "Step 4: self-review loop via evanflow-iterate."

Invoke evanflow-iterate:

• Run the project's quality checks (typecheck, lint, test — exact commands per CLAUDE.md)
• Re-read the diff (dead code, naming, deletion test, magic strings, error handling, type safety, security, test coverage, assertion correctness, scope creep, comments)
• Five Failure Modes pass (hallucinated actions, scope creep, cascading errors, context loss, tool misuse)
• For UI changes: chromium screenshot via chromium --headless --screenshot=..., then read the PNG
• Fix what's found, restart loop
• Hard cap of 5 iterations

Phase 5 — STOP

Announce: "Implementation complete. Stopping here per EvanFlow's no-auto-finish rule."

Report:

• What was built (file list, one-line each)
• What behaviors were added/changed
• What verifications passed
• Any deferred items (with reason)
• Anything the user should review before deciding next steps

Do NOT stage files, commit, push, merge, or open a PR. Wait for user direction.

Cross-Cutting: Context Compaction

Watch for drift symptoms throughout (re-asking established questions, contradicting earlier decisions, restating constraints already set). At any clean phase boundary (after design approval, after plan approval, after execution success), if the session feels heavy, proactively offer:

"We just finished [phase X]. Context is getting heavy — want me to invoke evanflow-compact to summarize anchors and prep for /clear before the next phase?"

Don't force it. Let the user decide.

Hard Rules (inherited from evanflow meta + this skill's specifics)

• Never auto-commit, never auto-stage, never auto-finish. Phase 5 is STOP. The user controls integration.
• Never invent values. File paths, env vars, IDs, function names, library APIs — if unsure, STOP and ask. Action-hallucination is the top failure mode.
• Respect checkpoints. After brainstorming and after planning, get explicit user approval before continuing. Not a tacit yes.
• Announce each phase. "Step N: [skill name] for [purpose]." This keeps the user oriented and able to interrupt cleanly.
• Don't mix up paths. If sequential was picked, don't switch to parallel mid-flight. If parallel, don't fall back to sequential silently. Surface the proposed switch and ask.
• Iterate has a hard cap. 5 iterations. If still finding issues at iteration 5, the original plan was wrong — stop and ask.

Hand-offs

This skill IS the entry point. It hands off TO other evanflow skills, not the other way around. The only "hand-off" out of evanflow-go is STOP at Phase 5, returning control to the user.

Special-purpose skills can be invoked mid-flow when relevant:

• New domain term emerged → invoke evanflow-glossary to update CONTEXT.md, then continue
• Design surfaces architecture concerns → invoke evanflow-improve-architecture first, then resume
• Interface shape is the hard part → evanflow-design-interface before plan
• Bug discovered mid-execution → evanflow-debug
• Substantial-feature scope reveals itself → upgrade brainstorming → evanflow-prd → writing-plans

These don't break the flow — they're sub-tools used inside the appropriate phase.

Why This Exists

Without an entry-point orchestrator, the user has to know which evanflow-* skill to invoke at each step. That defeats the cohesion property. With evanflow-go, the user says "evanflow this" once and the right sub-skill fires at the right time, with the right checkpoints preserved.

The skill is conductor, not autopilot. Checkpoints are real (brainstorm approval, plan approval, iterate hand-back). The user always has the option to interrupt, switch paths, or take manual control.
