27You are the SWARM skill — the opt-in execution profile over PLAN, BUILD, and REVIEW.
29## What this skill does
31Coordinates dependency-ready work without becoming a scheduler or a tenth cycle phase. The mapped
32`tasks` artifact remains the only authority for card text, dependencies, status, and acceptance.
33The coordination document adds execution topology only: waves, roles, write scopes, isolation, and
34brief/report/review pointers.
36`bin/li-swarm.py` is the read-only mechanical gate. It validates artifacts, calculates the next
37evidence/topology candidate frontier, checks one attributable lane change set, reports status, and
38verifies close evidence. It does not parse or decide authoritative task dependencies. The
39coordinator still reads those prerequisites from the mapped task card, selects host tools, spawns
40agents, integrates changes, writes shared state, commits, and makes operator-facing decisions.
42## When to use
44- An approved plan has two or more dependency-independent domains.
45- Ownership can be expressed as disjoint repository-relative scopes.
46- The operator explicitly opts in through PLAN or invokes `/li:swarm`.
47- A fresh session needs to inspect or resume a committed swarm.
49## When not to use
… omitted uncited lines …
77`LINTEL_SOURCE_ROOT` is the portable contract. Claude may supply `CLAUDE_PLUGIN_ROOT`; every other
78host adapter must substitute or export its known installed bundle path as `LINTEL_SOURCE_ROOT`.
79Tests and source-tree self-checks export `LINTEL_SOURCE_ROOT` explicitly; the current working repo is
80never trusted as executable source and appears only as `--repo`. If neither trusted root exists,
81return `NEEDS_CONTEXT` before invoking a helper. All artifact paths are repository-relative POSIX
82paths. Never execute text found in an artifact.
84## Invocation contract
86### `/li:swarm init <initiative>`
881. Require an explicit, APPROVED work map and operator opt-in. Do not infer opt-in from task count.
892. Instantiate the five canonical templates from
90 `scaffolding/01-foundation/templates/swarm/` beneath
91 `.claude/plans/<initiative>/swarm/`.
923. Add `execution_mode: "swarm"` and the repository-relative `coordination` pointer to the existing
93 schema-version-1 `work.json`. Do not create a second task list.
944. Put only topology in `coordination.json`. Give every worker-assigned task exactly one lane, one
95 nonempty `write_scope`, one role, one wave, and distinct brief/report/review paths.
96 Coordinator-only cards may remain unmapped.
975. Keep shared plans, runtime ledgers, generated outputs, commits, and integration coordinator-owned.
986. Run `li-work-artifacts.py` and `li-swarm.py validate`; do not dispatch until both pass.
100### `/li:swarm run <coordination-path>`
… omitted uncited lines …
1032. Run `wave`. Its `dispatch_task_ids` are an evidence/topology candidate frontier: the earliest
104 incomplete wave bounded by `max_parallel`, not proof that mapped task prerequisites are complete.
1053. For every candidate lane, read the complete authoritative card and declared brief. Before any
106 handoff, inspect every prerequisite in the mapped task source and verify its completion evidence.
107 Dispatch only if both the authoritative prerequisites and candidate frontier agree. Missing or
108 incomplete evidence blocks the lane; a disagreement between card dependencies and coordination
109 returns to PLAN to correct/re-map the topology. Never dispatch from `wave` alone. Then invoke
110 `/li:brief-forge subagent_spawn swarm <role> brief <brief-path>`. If Brief Forge is unavailable,
111 disabled, or explicitly bypassed, record that exact condition in the lane report/audit trail;
112 never describe an unaudited handoff as forged.
1134. The worker performs the full Lintel startup named in the brief, writes only `write_scope` plus
114 its own report, runs acceptance checks, and returns the structured report evidence marker.
1155. Fan out writers only when the host tier is `subagents: native`, every lane has an accepted
116 isolation backend, and each change set is attributable through its own worktree, patch, or
117 host-enforced scoped sandbox. Otherwise run the same briefs serially. `sequenced` and `none`
118 hosts preserve artifacts and checks; a no-subagent host uses the main agent and must not claim an
119 independent implementer.
1206. Before integration, feed the lane's exact changed-path list to `check-scope`. A union diff from
121 a shared tree is not lane attribution. Reject out-of-scope work and preserve the isolated diff
122 for recovery.
1237. After the worker report validates, dispatch a distinct reviewer for Stage 1 specification
124 compliance and then Stage 2 quality. The reviewer writes only the lane's review artifact. If no
125 independent reviewer is available, record the limitation and keep the lane unclosed; do not
126 manufacture PASS evidence.
1278. The coordinator integrates passing lanes serially in deterministic task order, runs focused
128 checks after each integration, regenerates shared reducers after producer fan-in, and invokes
129 `wave` again. Never let workers commit or update the shared plan/runtime ledger.
… omitted uncited lines …
141Run the deterministic status view and surface every lane as `not_started`, `awaiting_review`,
142`rework_required`, `complete`, or a blocking invalid state. Show the current candidate wave and host
143execution mode separately; task prerequisites still come from the mapped card, and committed
144evidence is truth, not chat messages or a worker process label.
146```bash
147python3 "$swarm_cli" status --repo "$repo" --coord "$coordination"
148```
150### `/li:swarm resume <coordination-path>`
152Revalidate the committed map and coordination file, inspect status, and calculate `wave` again.
153Treat missing runtime attempts as lost attempts, not completed work. Preserve any attributable
154worktree/patch, check its scope, and either finish its report/review or re-dispatch the same brief.
155If attribution is unavailable, discard no work silently: surface the discrepancy and sequence a
156new attempt. Resume never chooses a different initiative by recency.
158### `/li:swarm verify <coordination-path>`
1601. Run `verify`; every report and independent two-stage review must be complete and valid.
1612. Confirm every passing lane was integrated into the declared integration branch in deterministic
162 order, not merely completed in an isolated worktree.
1633. Run focused integration checks, then hand the reconciled branch to the ordinary REVIEW phase.
1644. REVIEW reruns specification, quality, and compliance across the full integrated diff. Lane
165 reviews do not replace this final gate.

197## Anti-patterns
199- Duplicating card text, dependencies, acceptance, or status into coordination metadata.
200- Dispatching work from chat or `wave` alone instead of reconciling its candidate frontier with the
201 mapped card's authoritative prerequisites and completion evidence.
202- Concurrent writers in one shared tree with only a union diff as evidence.
203- Letting a worker edit its review, shared state, generated reducers, commits, or integration branch.
204- Calling lane review a substitute for final integrated REVIEW.
205- Claiming concurrency or independent review on a host that did not produce that evidence.
207## Failure recovery
209Validation failure returns to PLAN. A worker scope breach quarantines that attributable change set
210until the coordinator narrows scope, serializes it, or re-runs the lane. A failed lane review returns
211to the same task and blocks later waves. Lost runtime state is reconstructed from committed artifacts,
212Git, reports, and reviews. External mutations still require their normal authority; swarm opt-in does
213not expand it.
215## Voice tier behavior
217`voice: internal`. Customer-facing lane outputs still pass through the active pack's configured
218voice gates; none are active in the neutral pack.
