dev-loop

English | 한국어

A Claude Code plugin that merges two things into one self-contained tool:

  • loop-orchestrator — a methodology-grounded verification loop (TDD / PDCA /
    Reflexion) for driving one task, or many parallel tasks, to "done".
  • dev-llm-wiki — a case-routed, semantic-layer knowledge base of software
    best-practices, edge cases, and development-process methodology (test-first
    ordering, review discipline, completion-evidence gates, agent-orchestration
    decision policy, agent-facing tool/instruction design), plus a planning
    methodology that grounds every design decision in it.

And it scales past one session: the orchestrate skill is a multi-session
orchestrator
over the same loop — it decomposes a goal into a dependency
graph, schedules parallel workers with a ready-set scheduler, and supervises
them Orca-natively when the Orca CLI is installed (raw tmux otherwise).
See Orca integration.

The one change from upstream loop-orchestrator: the plan step is no longer an
optional, pluggable role. It is fixed to the bundled wiki-plan methodology —
every non-trivial task plans by routing each design decision to a page in the
bundled wiki/ before any code is written. Since v1.17.0 that planning itself
runs as three gated phases — Analyze → Design → Decompose — each judged
mechanically before the next may start (see below). The rest of the loop is
unchanged.

On top of that, dev-loop adds a knowledge-capture loop: your sessions emit
verified insights, and knowledge-flush researches, de-dups, routes, and opens a
reviewed PR that grows the wiki over time.


Install (global)

Installed via the Claude Code plugin marketplace, so the skills and hooks apply
globally across every project you work in:

/plugin marketplace add choiyounggi/dev-loop
/plugin install dev-loop@dev-loop

Nothing is repo-scoped: the wiki-grounded loop, the ★ Insight capture
instruction, and the harvest hook are active in any repository you open.


The implementation loop

Run it two ways:

  • One task or one feature → the loop-implement skill — the single
    implementer
    . Step 2 runs wiki-plan once to produce an ordered task list where
    each task names the exact wiki pages that ground it; the loop then executes those
    tasks in the plan's order, and per task runs:
    0 define done → 1 analyze + load the task's named wiki pages → 3 tests (Red) → 4 implement (apply the pages' directives, no improvisation) → 5 run → 6 self-review → 6.5 independent test-quality audit → 7 judge (report the WIKI references applied) → 7b reflect + retry (bounded). There is no separate
    executor — the wiki-executor discipline (load only named pages, decisions win,
    BLOCKED-on-gap) is folded into this loop.
  • A whole goal, split across parallel worker sessions → the orchestrate
    skill: intake → decompose (approval gate) → dispatch loop: plan (wiki-plan) →
    implement + review (each session runs loop-implement) → integration test →
    pre-merge gate → merge. There is no wave barrier: a dependency graph plus slot
    accounting starts each task the moment its own dependencies are approved and a
    slot is free, so a finished worker is refilled instead of waiting out its
    batch's slowest member. A worker that finds its task far larger than the brief
    assumed can propose splitting it mid-run. Substrate: Orca when detected —
    offered at the task-split gate — drives spawn and supervision; otherwise raw
    tmux.
    On Orca each phase is a tracked
    Task + Dispatch, and the coordinator blocks on pushed worker_done /
    escalation / question mail instead of polling status files on a timer — so
    a worker's blocking question reaches you in seconds. On tmux the original
    status-file poll is unchanged. Either way, worker sessions escalate a
    guardrails ask instead of blocking, and a dead worker is detected fast rather
    than stalling the run.

Step 2 is fixed to wiki-plan — three gated phases

wiki-plan runs Phase A (Analyze) → gate-A → Phase B (Design) → gate-B →
Phase C (Decompose)
. Every exit condition is machine-checkable — plan-gate.sh emit writes a gates ledger and gate-check.sh --run judges it — so "the plan
is ready" is never a self-report:

  • Phase A — Analyze (plans/<feature>/analysis.md): requirements as an
    Example-Mapping table (an unresolved OPEN: question blocks entry to Phase B —
    Definition of Ready); ground truth with evidence attached (a re-runnable
    baseline test command, affected files each with the search that proved them,
    pinned-file constraints); time-boxed spikes for load-bearing unknowns; and an
    external best-practice search via the research role.
  • Phase B — Design (plans/<feature>/design.md): the wiki routing sweep —
    read INDEX.md, then each touched domain's index.md, and for every design
    decision find the page that owns it. Each decision row carries its choice, its
    wiki basis as a real path (gate-B greps that the page exists), the rejected
    alternative, and the test that would catch it being wrong. A decision no page
    covers is marked [no-wiki] and becomes an ingest candidate. The design is
    then reviewed by the plan-reviewer subagent — read-only, fresh context,
    so the session that wrote the plan never grades its own design.
  • Phase C — Decompose: ordered, small-model-sized tasks, each naming the
    exact wiki pages that ground it and the requirement (covers: R<n>) its
    verification proves — coverage is checked in both directions. Decisions are
    written as concrete values/code (never "as appropriate"), so the implementing
    pass executes instead of guessing.

Small tasks take a lite mode (machine-judged: small size, no [no-wiki], no
pins touched) that keeps the baseline pin and grounding grep but skips the
reviewer — recorded as an open ABANDON on the ledger, never a silent skip.
This is not a configurable role and cannot be turned off.

The wiki lives at the plugin root (wiki/, INDEX.md, AGENTS.md,
templates/); the wiki skills resolve their paths against ${CLAUDE_PLUGIN_ROOT}.

Configuring your tools (optional)

Like loop-orchestrator, dev-loop runs fully generic with no config, but you
can map its capability roles to your real tools so the loop uses them:

Role Map to
verify your project's test / build / QA command (the loop's run step)
knowledge your domain/team wiki or knowledge MCP (external facts)
explore code/symbol search (LSP, ripgrep, a source-search CLI)
tacit past incidents / danger-zone lore
design Figma / visual-spec MCP (UI work)
intake issue tracker (orchestrate's work-list)
research external best-practice/pitfall search (wiki-plan Phase A/B). Fixed fallback when unset: brave-search MCP if present → built-in WebSearch → open ABANDON

(plan is not a role — the plan step is fixed to wiki-plan. And the bundled
best-practice wiki/ needs no config; knowledge is a separate external wiki.)

Set it up with /dev-loop:configure, which writes ~/.claude/dev-loop/tools.json
(global) or <repo>/.dev-loop/tools.json (per-repo, team-shared). Precedence is
git-config style: defaults < ~/.claude/dev-loop/tools.json < <repo>/.dev-loop/tools.json.
A SessionStart hook nudges you (at most weekly, then never) if you haven't
configured anything — silence it with DEV_LOOP_CONFIG_NUDGE=0. Legacy
loop-orchestrator config paths are still read as a fallback. See
references/tool-profile.md and examples/tools.example.json.


Orca integration — supervision, not just spawning

orchestrate treats Orca as a first-class substrate, not a terminal spawner.
When the orca CLI is on your PATH the coordinator offers it at the task-split
gate, and from then on the whole run flows through Orca orchestration:

  • Provenance — one Run per orchestration; every task phase (plan /
    implement / rework / merge-prep) is a tracked Task + Dispatch, so "who is
    doing what, and did it settle" is queryable state, not a guess.
  • Event-driven waits — the coordinator blocks on pushed worker_done /
    escalation / question mail (orca-wait.sh) instead of polling status
    files on a timer. A worker's blocking ask reaches the coordinator in
    seconds and is answered with orchestration reply; a dead Orca runtime is a
    distinct exit, never a silent timeout.
  • Env-carrying worker start — orca-worker-start.sh composes the worktree,
    an agent terminal that carries the guardrails escalation contract
    (GROUNDWORK_ESCALATION_DIR / GROUNDWORK_TASK_ID), and the Dispatch
    binding; on re-entry it probes for a live agent first, so one worktree never
    ends up with two agents.
  • Liveness is two questions — orca-worktree-alive.sh (is the terminal
    there?) and orca-worker-stalled.sh (is the pane actually moving?) —
    because a wedged worker passes the first check for hours.

Without Orca, the same run gets the same protections over raw tmux,
file-based: a worker writes a blocking question with ask-coordinator.sh and
the watch surfaces it (exit 6); a silent pane surfaces as a stall (exit 7) with
a classify-then-act playbook (chooser / usage-limit / finished-but-silent); an
on-screen chooser is answered with allowlisted key events
(send-prompt.sh keys); and every launch pre-seeds the status record, so a
worker that dies during planning is caught instead of waited out. The
guardrails escalation contract is identical on both substrates.

One setup note for auto-mode coordinators (tmux): the launcher starts each
worker as claude --permission-mode bypassPermissions, which an auto-mode
permission classifier flags as privilege escalation — it cannot see the
guardrails deny-net that makes it safe. If your coordinator session runs in
auto mode, the three worker-management scripts (launch-session.sh,
send-prompt.sh, watch-status.sh) need pre-approval. The coordinator
handles this at onboarding: it probes read-only
(install-permission-rules.sh --check), and if the rules are missing it asks
you once — on your explicit yes it runs the bundled installer (idempotent,
backed-up, atomic; never silent), otherwise it shows you the snippet to paste
yourself. safe-cleanup.sh is deliberately excluded so destructive verbs keep
their normal review, and a blocked coordinator stops and re-asks rather than
working around the classifier.


The knowledge-capture loop

The wiki is meant to grow from what you actually learn. Three moving parts:

  1. Capture (global, automatic). A SessionStart hook injects a standing
    instruction: whenever, in any repo, you discover a verified best-practice or a
    real edge case worth persisting, emit a compact ★ Insight block (trigger /
    directive / why / evidence / domain / tags).

  2. Harvest (automatic, offline). A Stop hook scrapes those blocks from the
    session transcript into a local queue (~/.dev-loop/queue/). It dedupes
    against both the session's queue file and the already-flushed store
    (.processed.jsonl), caps a session at 10 rows as a runaway backstop, and
    cleans up emptied queue files. It never edits the wiki and never opens a
    PR — harvesting is cheap and non-blocking.

  3. Flush → verified PR (automatic, or on-demand). The queue is drained by the
    knowledge-flush pipeline. For each candidate it must, before any PR:

    • research & verify the best-practice against real sources (official docs,
      primary references) and assign a confidence (verified / field-tested /
      unverified — never a fabricated citation),
    • check existing layers for duplicates to merge into and pages to link
      (naming the page ids it actually read),
    • check open knowledge/* PRs so sibling flushes don't pile up duplicate
      PRs — each candidate is folded into an in-flight PR, dropped as a pending
      duplicate, or ingested as new,
    • decide the target layer/category (or justify a new category),
    • then run wiki-ingest and write an INGEST_REPORT.md.

    It opens one PR per flush and never auto-merges. Each contributor's PR
    is committed and opened under their own git/gh identity (never a hardcoded
    account, never an assistant); the repo owner reviews the open
    dev-loop:knowledge PRs and merges or rejects each one.

    Two ways it runs:

    • Automatic — the hooks/auto-flush.sh Stop hook fires the pipeline in a
      detached, headless claude run when the queue crosses a threshold and the
      rate-limit window has elapsed, so PRs appear without you doing anything.
      Guarded: kill switch DEV_LOOP_AUTOFLUSH=0, once per
      DEV_LOOP_AUTOFLUSH_INTERVAL (default 3600s), only at
      DEV_LOOP_AUTOFLUSH_MIN (default 3) pending items, an owner-token
      single-flight lock shared with the manual flush below
      (DEV_LOOP_FLUSH_LOCK_TTL, default 900s, before a crashed holder's lock
      is reclaimable) plus a per-run queue claim (DEV_LOOP_CLAIM_TTL, default
      3600s) so the two entry points never ingest the same candidate, and
      recursion-safe. Needs claude + gh on PATH and gh authenticated; if
      either is missing it silently no-ops and you fall back to manual.
    • Manual — invoke /dev-loop:knowledge-flush any time to drain the queue now.

This ordering is enforced by a hook

hooks/pre-flush-pr-gate.sh (PreToolUse) blocks gh pr create on a
knowledge branch unless the INGEST_REPORT.md exists and has all four sections
(## Verified best-practice, ## Existing-layer check, ## Open-PR check,
## Routing decision) filled with real content. The Existing-layer check must
carry a Pages read: <id>, … line, and each id is resolved against the
checkout's wiki/ — a report citing pages that don't exist fails closed. The
gate is narrowly scoped to knowledge-flush PRs, so it never interferes with
ordinary gh pr create in any repo.


Skills

Skill Role
loop-implement The single implementer — consumes the wiki-plan and executes its tasks in order (loading each task's named wiki pages) through the verification loop. Plan step = wiki-plan.
orchestrate The multi-session orchestrator — split one goal into parallel worker sessions, each running loop-implement — over Orca when detected (Task/Dispatch tracking, event-driven worker_done/ask/escalation waits, native liveness), else tmux with a hardened watch (worker question channel, stall surfacing, allowlisted chooser keys). Scheduling is a dependency graph plus slot accounting, not wave barriers: ready-set.sh says what may start now, the slot count is proposed at Gate 1 and bounded by LO_MAX_SESSIONS, and a failed dependency surfaces as a reported deadlock rather than a silent wait. Per-role model selection: a cheap worker model, a strong planner/auditor. Workers escalate guardrails asks instead of blocking, may propose splitting an over-large task mid-run, and dead workers are detected. Both human gates (task split + substrate, pre-merge) are put to you as AskUserQuestion choosers, enforced by orchestrate-ask-gate.sh.
wiki-plan The fixed plan methodology — three gated phases (Analyze → Design → Decompose): evidence-backed analysis, wiki-routed decisions independently reviewed by the plan-reviewer subagent, then ordered, page-navigated tasks. Gates are judged mechanically (plan-gate.sh + gate-check.sh); orchestrate refuses to dispatch a plan without gate evidence.
wiki-ingest Add verified knowledge to the right semantic layer (used by knowledge-flush).
wiki-query Answer a question from the wiki with citations.
wiki-lint Health-check the wiki.
knowledge-flush Research + verify + route queued insights → one reviewed wiki PR.
configure Set up the capability-role tool profile (map your wiki, test command, etc.).
