flow-execute

flow:execute — Execute Phase (OpenClaw)

Load an intent-driven plan, group tasks into dependency-ordered waves, dispatch specialist sub-agents in parallel within each wave via sessions_spawn, run a mandatory critic gate between waves, then dispatch the sentinel for an evidence-based final sign-off. This is the OpenClaw port of fakoli-flow execute; the canonical driver is the fakoli-orchestrator agent.

The critic gate runs after EVERY wave that writes code. It cannot be skipped. Proceed only when the critic returns PASS (or SHOULD FIX / NIT with no MUST FIX).

OpenClaw mapping (how this differs from the Claude Code original)

Claude Code	OpenClaw
Agent(subagent_type="fakoli-crew:welder", prompt=…)	sessions_spawn(agentId="fakoli-welder", task=…) then sessions_yield
claude plugin list | grep fakoli-crew	openclaw agents list | grep '^- fakoli-'
model tier picked per dispatch	tiers are config-routed already: welder/smith/scout/herald/keeper → sglang/qwen3.6-35b-a3b-local; guido/critic/sentinel/orchestrator → openai/gpt-5.5
each agent has fresh context	same — each spawned session is isolated; pass only the scoped packet

Spawn depth: the human/main agent spawns fakoli-orchestrator (depth 1); the orchestrator spawns specialists (depth 2). agents.defaults.subagents.maxSpawnDepth must be ≥ 2 (it is).

Async yield (important): sessions_spawn is non-blocking; children announce results back to the parent session, and sessions_yield awaits them. A single CLI turn returns after the first yield resolves — the orchestrator session then continues across turns as later children announce. When driving from a script, poll the scratch dir for the terminal artifact (the sentinel scorecard) rather than assuming one CLI turn finishes the whole wave.

Process

1. Load the plan. Read it fully. Extract each task's Intent, Acceptance, Scope, Agent, Verify, and Depends on:. If the file is missing, ask for the path.

2. Derive the run id + scratch root. run-id = <plan-basename>-<YYYYMMDDHHmm UTC>. Scratch root (gitignored, outside VCS — fakoli-style P10): <project>/.fakoli/runs/<run-id>/. Use ABSOLUTE paths; inject each agent's own status-file path into its packet. Log it once.

3. Detect specialists. openclaw agents list. If the fakoli-* crew is present, dispatch to fakoli-<role>. If not, fall back to the main agent / general for every role (the pipeline still runs; you lose specialization). Log which mode you're in.

4. Group into waves from Depends on: — no deps → Wave 1; deps all in Wave N → Wave N+1. Same-wave tasks are independent and must target non-overlapping files.

5. For each wave:

   • Dispatch in parallel: one sessions_spawn per task, each carrying ONLY its scoped packet (Intent, Acceptance verbatim, Scope = exact files, Upstream context = prior waves' Decisions, Verify command, and the absolute status-file path to write). Then sessions_yield.
   • Collect status files from the scratch root. Confirm each is done/COMPLETE. Surface any BLOCKED/NEEDS_REVIEW to the user — never swallow them.
   • Language verification before the gate: TypeScript npx tsc --noEmit; Python ruff check . && mypy .; Rust cargo check. On failure, dispatch welder to fix, re-run.
   • Critic gate (non-negotiable): sessions_spawn(agentId="fakoli-critic", …) with the wave's modified-file list + the relevant acceptance criteria. The critic re-runs the verify commands itself (evidence over claim) and returns MUST FIX / SHOULD FIX / CONSIDER / NIT.
     • No MUST FIX → proceed.
     • MUST FIX → fix cycle: spawn the owning specialist with the exact findings, re-spawn critic, max 3 cycles, then escalate to the user.

6. After the final wave: sentinel. sessions_spawn(agentId="fakoli-sentinel", …). Sentinel runs EVERY plan Verify command, quotes exit codes + output, and writes a pass/fail scorecard to <scratch>/sentinel-final.status. Confirm the prior wave's edits are on disk before dispatching sentinel (avoid the read-before-write race). Sentinel does not trust prior claims.

7. Report. Waves run, tasks completed, files modified, critic findings (MUST FIX resolved / SHOULD FIX logged), sentinel verdict. End with WAVE-OK only if the sentinel scorecard passes all acceptance criteria, else WAVE-BLOCKED: <reason>.

Packet template (per spawned task)

Task: <name>
Intent: <one sentence, from plan>
Acceptance criteria: <verbatim from plan>
Scope: <exact files>
Upstream context: <Decisions extracted from prior-wave status files>
Verify: <exact command from plan>
Write your status file to: <abs scratch>/<role>-<task>.status  (status: IN_PROGRESS at start, done when all criteria met + Verify passes)

Notes

• Status-file format + reading/writing rules: see references/status-protocol.md.
• Wave-assignment DSL + capability matrix: references/wave-engine-ref.md.
• Keep packets tight and tool surface minimal (Fakoli: intent over recipe, specialist over generalist, evidence over claim, durability over chat).
