Loop Tasks Driver

Drive a Compozy techspec to completion as a self-healing continue loop: each iteration detects the current phase, runs exactly one phase action, writes memory, updates state.yaml, and prints the iteration summary — then continues at detect unless the outcome is an evidence-backed external blocker or Phase E. A failed command stays inside the current phase action: diagnose, repair, and rerun it before writing iteration state. Filesystem state still resumes cleanly if the session ends mid-loop.

The loop is a five-phase state machine:

Compatible with ~/dev/ai/codex-loop-plugin goal mode; the plugin itself is never modified. Prefer in-session continue over waiting for a Stop→restart — restarts are a resume safety net, not the driver.

Inputs

• <slug> — directory name under .compozy/tasks/.
• <goal_text> — verbatim [[CODEX_LOOP goal="..."]] text or the manual reason for the run. Captured once at bootstrap into state.yaml.goal_signature.
• --frontend <claude|cursor> — optional. Selects the frontend worker agent and activates the herdr frontend lane for the whole loop. Captured once at bootstrap into state.yaml.frontend_agent; when absent, every task runs locally. Syntax examples in references/goal-header-template.md.
• A pre-authored .compozy/tasks/<slug>/_techspec.md. Without it, bootstrap stops with a blocker.

Helper scripts

Bundled under .agents/skills/cy-loop-tasks/scripts/ — stdlib-only Python 3.11+, no network, no model calls. Invoke by the explicit repo-root paths shown in the workflow steps.

Herdr delegation lanes

Two lanes dispatch work to herdr worker TUIs. Before any dispatch, read references/herdr-delegation.md in full and activate the herdr-orchestration skill it builds on.

• Frontend lane (Phase B) — active only when state.frontend_agent is set. While active, every frontend task or slice is dispatched to the selected worker (claude → Claude Code Opus at xhigh effort, cursor → cursor-agent --yolo --model grok-4.5); the orchestrator session stays in orchestration mode and never implements frontend work itself.
• QA-report lane (Phase C) — always active. qa_report is produced by a Claude Fable 5 worker (claude --permission-mode auto --model claude-fable-5), launched direct — never plan-first. The orchestrator runs qa_execution itself.

Workflow

Each iteration is one detect → phase action → memory → state → summary cycle. After a completed (non-blocked) summary that is not Phase E, continue at Step 1 in the same turn — do not end the session between rounds.

If any command, gate, worker, or artifact check fails during a phase action, read references/recovery-loop.md in full immediately and run its repair loop. Do not write final iteration state or print the summary for an intermediate failure.

Step 1 — Detect.

1. Print pwd and confirm the working directory is the repo root (the directory containing .compozy/tasks/). On mismatch, locate that root, change into it, and confirm again; block only when the task tree is absent.
2. Activate cy-workflow-memory so its protocol is loaded for later use (once per session is enough; re-activate only if context was dropped).
3. Run python3 .agents/skills/cy-loop-tasks/scripts/detect-phase.py <slug>. The printed line decides the whole iteration; the output catalog and entry/exit conditions are in references/phase-transitions.md.

Done when: detect-phase emitted exactly one supported phase/action line and the matching branch below is selected.

Step 2 — Run exactly one phase branch.

Phase 0 — Bootstrap

1. Confirm .compozy/tasks/<slug>/_techspec.md exists. Missing → scaffold memory/MEMORY.md from references/memory-protocol.md, record the blocker under ## Open Risks, print the iteration summary with outcome=blocked, and stop (state.yaml does not exist yet, so there is no update-state call).
2. Run python3 .agents/skills/cy-loop-tasks/scripts/init-state.py <slug> --goal "<goal_text>", adding --frontend <claude|cursor> when the invocation text carries the parameter. Mode auto-detects: tasks when _tasks.md plus at least one task_*.md exist, else free.
3. Activate cy-spec-preflight for the phase the next iteration enters (tasks, or task-body when a single concrete file is next).
4. Scaffold .compozy/tasks/<slug>/memory/MEMORY.md with the canonical sections from references/memory-protocol.md.
5. Run python3 .agents/skills/cy-loop-tasks/scripts/update-state.py <slug> --phase 0 --action "bootstrap (mode=<mode>)" --outcome completed --memory-written "memory/MEMORY.md".

Done when: state.yaml exists and memory/MEMORY.md has the canonical sections.

Phase B mode=tasks — execute one task

1. Take the task printed by detect-phase (task=<stem>). Read .compozy/tasks/<slug>/<stem>.md and confirm frontmatter status: is pending or in_progress. Frontmatter wins — on drift, reconcile with update-state.py <slug> --task-completed <stem> for already-finished tasks or --reconcile-tasks for a late-authored graph, then re-run detect-phase.
2. Activate cy-spec-preflight in task-body mode for the picked file.
3. Resolve the shared and current memory paths from references/memory-protocol.md and pass them into the lane that executes the work.
4. Frontend lane — when detect-phase printed lane=frontend agent=<x>: dispatch the task to that worker per references/herdr-delegation.md. The worker owns implementation, memory updates, scoped validation, and cy-final-verify evidence. It never commits. Skip step 5.
5. Local lane — activate cy-execute-task on the picked file with auto-commit disabled. Run the task's scoped validation, then cy-final-verify. Skip any per-task peer-review step the task file requests — that review is Phase D (see Critical Rules).
6. Confirm memory is updated (written locally, or verified from the worker) and that cy-final-verify evidence is PASS before any state flip. For the frontend lane, verify the worker's evidence instead of re-running verify.
7. Run python3 .agents/skills/cy-loop-tasks/scripts/update-state.py <slug> --phase B --task-completed <stem> --action "executed <stem>" --outcome completed --memory-written "memory/<stem>.md,memory/MEMORY.md" --verify-pass.
8. Run python3 .agents/skills/cy-loop-tasks/scripts/commit-checkpoint.py <slug> --task <stem>. Stdout is a commit SHA or SKIP: no changes; copy it into the iteration summary. On exit 1, enter the repair loop and retry the normal checkpoint after its root cause is fixed. Never bypass the hook with --no-verify.

Done when: task frontmatter, memory, state.yaml, and the checkpoint result all reflect the same completed task.

Phase B mode=free — execute one slice

1. Re-read _techspec.md deliverables and acceptance in full; compare against state.progress.checklist[].
2. Pick the smallest coherent slice (≤ ~4 hours) that advances at least one acceptance criterion; capture its text exactly.
3. Run python3 .agents/skills/cy-loop-tasks/scripts/update-state.py <slug> --add-progress "<slice text>" --action "slice picked" --outcome completed.
4. Re-read state.yaml; the current memory file is memory/free-iter-<NNN>.md, <NNN> = the new checklist entry's iteration, zero-padded to three digits.
5. Frontend lane — when state.frontend_agent is set AND the slice's owned paths are exclusively frontend surfaces (classification in references/herdr-delegation.md): dispatch per that reference. The worker owns implementation, memory updates, scoped validation, and cy-final-verify evidence; it never commits. Skip step 6.
6. Local lane — implement the slice, record decisions and learnings in the current memory file, run scoped validation, then cy-final-verify.
7. Confirm memory is updated and cy-final-verify evidence is PASS. For the frontend lane, verify the worker's evidence instead of re-running verify.
8. Acceptance self-check: when every techspec criterion has a completed checklist entry, add --deliverables-complete to the step 9 call.
9. Run python3 .agents/skills/cy-loop-tasks/scripts/update-state.py <slug> --phase B --complete-progress "<slice text>" [--deliverables-complete] --action "slice <text>" --outcome completed --memory-written "memory/free-iter-<NNN>.md,memory/MEMORY.md" --verify-pass.
10. Run python3 .agents/skills/cy-loop-tasks/scripts/commit-checkpoint.py <slug> --slice "<slice text>" with the exact step 3 text — same SKIP / exit-1 semantics as mode=tasks step 8.

Done when: the slice's checklist entry is completed and the checkpoint result is recorded.

Phase C — QA

Run only the printed action.

qa_report — dispatched, never authored locally:

1. When release-grade runtime scope needs a lab and no active bootstrap-manifest.json exists, activate the project's QA bootstrap skill first (e.g. agh-qa-bootstrap in AGH) when installed.
2. Dispatch the Fable 5 worker per references/herdr-delegation.md (QA-report lane). The worker activates qa-report with qa-docs-path=docs/qa and updates journey flows, docs/qa/scenarios/ files, and cycle charters.
3. Verify the worker evidence (each reported artifact exists, no worker commit), then run python3 .agents/skills/cy-loop-tasks/scripts/update-state.py <slug> --phase C --qa-report-done --action "qa-report produced" --outcome completed --memory-written "memory/qa-report.md,memory/MEMORY.md".

qa_execution — local:

1. Activate qa-execution with qa-docs-path=docs/qa; it writes the dated run report at docs/qa/reports/<YYYY-MM-DD>-<slug>.md and updates scenario-file verdicts.
2. When the report is "not ready" or a Blocks-Completion/Data-Loss bug is open, keep the Phase C action open: repair every in-scope bug, rerun the affected QA, and repeat qa-execution through the recovery loop. Do not set --qa-execution-done on an intermediate report.
3. Once the report is ready, run python3 .agents/skills/cy-loop-tasks/scripts/update-state.py <slug> --phase C --qa-execution-done --action "qa-execution produced" --outcome completed --memory-written "memory/qa-execution.md,memory/MEMORY.md" --verify-pass.

mode=tasks addition: when the printed QA action corresponds to the pending QA task file, flip that task's frontmatter status: to completed and add --task-completed <stem> to the same update-state call so tasks.pending drains.

Done when: the printed QA artifact exists on disk and its flag is recorded in state.yaml.

Phase D — peer-review rounds until SHIP

One round per iteration; detect-phase re-emits peer_review until the verdict is SHIP on a verify-PASS tree. Enter this phase only after every Phase B task or slice is complete and both QA flags are true.

1. Activate deep-review for the round number printed by detect-phase, scoped to the loop's full diff: --base = the ref the loop started from when known (default main), --spec .compozy/tasks/<slug> (contract conformance), --subagent codex (cross-LLM reviewer lane — the implementing model never solely reviews its own work). Later rounds ride deep-review's incremental state; never pass --full mid-loop.
2. The loop is the deciding authority over the round: remediate every confirmed finding and every nitpick from the round's review.md in this same iteration, then re-run the project verification gate. The round's verdict is the SHIP/FIX_BEFORE_SHIP/REWORK value in review.md/state.json.
3. Update memory/peer-review.md (a ## Round <N> section per round), then run python3 .agents/skills/cy-loop-tasks/scripts/update-state.py <slug> --phase D --review-round-done <SHIP|FIX_BEFORE_SHIP|REWORK> --action "peer-review round <N> (<verdict>)" --outcome completed --memory-written "memory/peer-review.md,memory/MEMORY.md" --verify-pass. The call uses --verify-pass: a failed post-remediation gate stays inside the repair loop, and a SHIP verdict on a failing tree is void.
4. Run python3 .agents/skills/cy-loop-tasks/scripts/commit-checkpoint.py <slug> --review-round <N> — same SKIP / exit-1 semantics as Phase B.

Done when: the round's review.md exists with a verdict, every confirmed finding and nitpick from it is remediated (or the verdict was SHIP), and state.yaml records the round.

Phase E — done

1. Run a final cy-final-verify and confirm state.verify.last_status=PASS. A regression enters the repair loop and Phase E remains open until the fresh gate passes; skip the done-signature while repairing.
2. Walk the Phase E section of references/checklist.md; every box must pass.
3. Print the iteration summary block from assets/iteration-summary.template.md with phase_out=E and checkpoint field n/a (phase != B/D).
4. Print the literal contents of assets/done-signature.txt on its own line — the codex-loop goal-check confirmation scans for it.
5. Stop — Phase E is the only successful terminal.

Done when: the Phase E checklist passes, the iteration summary is printed, and the done-signature is the final output line.

Step 3 — Self-audit, summarize, then continue.

1. Walk references/checklist.md for the phase just executed; every box must pass before summarizing.
2. Print the iteration summary block from assets/iteration-summary.template.md (Phase E already printed it and adds only the done-signature line).
3. Continue gate: stop only when phase_out=E or the external-blocker criteria in references/recovery-loop.md are proven and outcome=blocked. Otherwise re-enter Step 1 immediately — the summary marks the round; it does not end the session.

Done when: the phase checklist passes, its summary is printed, and control either returned to Step 1 or stopped at a permitted terminal.

Memory protocol

Memory goes through the cy-workflow-memory skill — the exact paths per phase are in references/memory-protocol.md. Update memory before flipping any tracking field.

Goal-mode integration

The canonical [[CODEX_LOOP ...]] header, the manual invocation text, and --frontend syntax live in references/goal-header-template.md.

Critical Rules

• One phase action per iteration; repair failures inside that action, then continue at detect until Phase E or a proven external blocker — never idle between rounds waiting for a restart or re-invocation.
• state.yaml mutates only through init-state.py and update-state.py; hand-edits void resume guarantees. There is no top-level current_phase — detect-phase.py derives it from durable state and filesystem truth every run.
• Frontmatter status: on task_NN.md is the source of truth; reconcile state.yaml when they disagree.
• Memory updates precede status flips. Always.
• Frontend lane: state.frontend_agent set → herdr dispatch is the only way frontend work gets implemented; null → every task runs locally. Workers are interactive TUIs launched via rtk herdr agent start — a pane streaming raw JSON is a broken headless delegation: interrupt and relaunch per references/herdr-delegation.md.
• qa_report is always produced by the Fable 5 worker; qa_execution always runs locally.
• Every Phase B task or slice runs scoped validation then cy-final-verify before its checkpoint commit. A FAIL opens the repair loop; only the final PASS closes the phase action.
• Peer review (deep-review) runs only in Phase D. Per-task peer-review instructions inside task files or specs are superseded by this loop's phase machine — note "deferred to Phase D" in the task memory and move on.
• Phase D repeats in consecutive rounds until SHIP; every non-SHIP round remediates all blockers and nits before the next round starts.
• Checkpoint commits (Phases B and D) belong to the orchestrator: cy-execute-task runs with auto-commit disabled, and every worker packet forbids committing. The checkpoint captures code, memory, task frontmatter, the master tasks file, and the advanced state.yaml in one atomic, restorable snapshot.
• Phase E requires qa.report_done=true, qa.execution_done=true, review.ship=true, and verify.last_status=PASS.
• Do not regenerate the loop's input graph with cy-create-tasks, cy-create-techspec, cy-tasks-tail-qa-pair, or cy-web-docs-impact. The only exception is a repository-mandated two-touch corrective TechSpec: activate its required spec skills, let the loop decide choices already bounded by the current goal/contract, persist the corrective design, and continue without replacing the original task graph.

Error Handling

• Any failure — read references/recovery-loop.md in full and execute it before mutating iteration state. Failed commands are repair work, not blockers. Use outcome=blocked only after its external-blocker test passes.
• _techspec.md missing at bootstrap — record the blocker in memory/MEMORY.md ## Open Risks, print the iteration summary with outcome=blocked, stop. No update-state call: state.yaml does not exist yet.
• Mode disagreement — init-state.py exits 4 when --mode contradicts the filesystem. Reconcile by adding/removing _tasks.md before bootstrap, or run update-state.py <slug> --reconcile-tasks when the task graph was authored after a free-mode bootstrap.
• state.yaml parse failure — detect-phase.py exits 1 with the parse error on stderr. Diagnose the malformed writer or interrupted write from evidence and repair it without discarding unrelated worktree changes.
• commit-checkpoint.py exit 1 — repair the hook or commit failure and retry normally. If the repair changes tracked source after the last PASS, rerun cy-final-verify before retrying. SKIP: no changes is success.
• Worker launch or delegation failure — the pane shows raw JSON instead of a TUI banner, rtk herdr agent list stays unknown, or the status wait times out with no progress: interrupt (rtk herdr pane send-keys <pane_id> ctrl+c) and relaunch once via rtk herdr agent start; if it fails again, diagnose and repair the worker environment through the recovery loop.
• Delegated run lacks PASS evidence or artifacts, or committed anyway — keep the phase open, recover the missing evidence or rerun the lane, and do not advance. A worker commit is a contract breach that requires preserving the worker's work and repairing checkpoint ownership before continuing.
• Invalid peer-review round (missing or malformed review artifacts, or no verdict) — the round does not count; follow deep-review error handling and re-run it.
• Two-touch rule — on the third corrective touch, replace patching with the structural redesign required by the repository, validate it, and continue. It becomes a blocker only when that redesign needs an external product decision or authority unavailable to the loop.
• External blocker proven — record the evidence and exhausted alternatives in memory, call update-state.py with --verify-fail --blocker <text> --outcome blocked, print the summary, and stop without the done-signature.
