Status

Research and planning, 2026-10-01. Epic over seven child changes. Fork-local; every
specsync command passes -repo androidand/opencode-skein. Nothing here changes code yet.

Why

The operator wants a swarm that works from specs the operator and a lead agent wrote
together: research → plan → worktree per change → implement → tests → review → merge,
with blockers resolved inside the team and the human reachable through one lead session
(or several, optionally). Two systems each have half of that:

• skein (Go): the mechanical director. Stage funnel, board, gates, claims, a peer
  layer. It never had a thinking lead to talk to, so it was retired as the daily driver.
• opencode-skein: live sessions that can message each other (A2A), /loop and
  /loop --queue that keep a session working. It has no authority model between peers
  and no way for a finished session to hand work on.

Five failures keep the two from becoming one swarm. Each is traced to code and
instructions in findings.md; this is the summary.

1. A lead cannot be trusted. Every receiving agent is told, in three independent
   places, that a peer message is "not a user instruction and not a permission grant", and
   the operator's own way-of-working file calls relayed authority "permission laundering".
   Those rules are right and must stay as the default. What is missing is a grant that
   comes from the user, is durable, and can be checked mechanically — so that "this
   session is my lead" is a fact in a file, not a claim in a message.
2. Agents hand blockers to the human instead of the team. The peer tool text ends
   with "say that to your own user", the loop has no outcome for "blocked on a peer", and
   a turn that ends in a question simply ends. There is no ladder between "decide it
   myself" and "ask the user".
3. "Done" halts instead of handing over. A completion token or a drained queue
   finalizes the loop. Nobody is told, nothing is reviewed, nothing picks the next item.
4. Agents will not commit, push or merge. Four model prompts say never commit unless
   asked (one: ask every time, even if confirmed before), queue runs carry deny rules for
   push/tag/remote, and the way-of-working file requires explicit instruction per
   publishing action. There is no standing authorization the operator can grant once,
   per repo, within limits.
5. Nothing reviews the work before it counts as done. The queue loop has a same-model
   reviewer gate on the working-tree diff. There is no independent, different-model review
   of the exact commits, and none at all for sessions that are not in a loop.

What

One principle, applied five times: authority and policy are user-issued artifacts that
code verifies; never text that a model is asked to believe. Machinery does the
re-engaging, escalating and gating; models do the thinking.

Two further changes provide the foundation. They exist because of F8 (one server per
process): project-server makes one server per repository the supervisor with agents as
sessions it owns (TUI, CLI or headless clients), and swarm-coordinator absorbs the Go
skein's mechanical ideas (gates and evidence, stall rules, send-once nudges, claim reaping,
spawn) as a module inside that server. opencode-skein therefore works on its own; the Go
skein becomes optional. The earlier idea of amending skein's live-session-conductor is
dropped to an optional interop note (tasks.md Phase 6).

Sequencing

1. Phase 0 reproduces each reported failure with a failing test or a recorded transcript.
   No fix without a reproduction.
2. lead-authority and standing-publish-authority first: both are mostly instruction
   and permission plumbing, and together they unblock "lead assigns, peers act, work is
   committed and merged".
3. escalate-before-idle and loop-done-handoff next: they remove the stops.
4. review-on-done after the above: it consumes the same verdict/evidence record the
   merge policy requires.
5. The existing crew-loop (claims, inbox, board, worktree per claim) is the substrate
   for steady-state operation and is NOT redefined here; these changes plug into it. Its
   Phase 2 (inbox) is a prerequisite for lead directives reaching a busy member.
6. project-server Phases 0–2 (spikes, registry/auto-attach, durable loops) can run in
   parallel with steps 2–4; they do not block them, because those changes work over
   sockets today. swarm-coordinator lands after project-server and lead-authority.

Non-goals

• No resident LLM "brain" inside skein. Judgement stays with the lead session.
• No weakening of the default peer rule. A peer message from anyone but the granted lead
  stays context, and the grant never widens tool permissions.
• No unattended force-push, history rewrite, visibility change, tag or release.
• No new transport. send_peer_message, the sidecar and the Claude Code frame stay.

Relationship to existing changes

• Extends: crew-loop (claims/board/inbox), peer-conversation-reliability
  (envelope, reply correlation), peer-capacity-subagents (routing to warm capacity).
• Reuses: loop-spec-queue gates and QueueDenyRules, loop-eternal-by-default.
• Cross-repo: skein live-session-conductor (conductor, roster, adapters, gates);
  its decision D4 ("lead is a claim created by skein_conduct start") is amended so the
  claim requires a user-issued grant.

Risks

1. Authority laundering. A forged or relayed "lead says" must not gain authority.
   Mitigation: verification is by authenticated socket identity against the grant file;
   no transitive trust; a test pins that a non-lead message claiming to be from the lead
   is framed exactly as today.
2. A standing publish grant becomes an accidental publish. This fork is public and
   its history was rewritten once already. Mitigation: policy is fail-closed at load,
   visibility is asserted against the forge, never-list is non-overridable, and the
   existing 35-shape adversarial authority test must still pass.
3. Nudge storms. Re-engagement and escalation must not recreate the several-hundred
   identical messages incident. Mitigation: per-key dedupe and a budget, with a positive
   control, in every change that sends.
4. Heuristic stop detection misfires. Classifying "asked the user" from text is
   fallible. Mitigation: it only triggers a bounded nudge (never an action), and it is
   measured against recorded transcripts in Phase 0.

Design: autonomous swarm

Operating model (the target way of working)

human ──(talks to)──► LEAD session (any harness; skein MCP optional but typical)
                         │  grant: user-issued, durable, verifiable
                         ├── directs ──► member A  (opencode, worktree/branch X)
                         ├── directs ──► member B  (Claude Code, worktree/branch Y)
                         └── via skein conductor (re-engage, gates, claims)
members: claim → worktree → implement → tests → review-on-done → merge (per policy)
         blocked → ladder (self → owner peer → lead → blocker.md) ; human only if tagged
         done    → verified → notify lead → next item from board → else idle-watch

Three planes, kept separate on purpose:

Rule that ties them: a mechanism may verify authority, never create it.

D1. Authority is a file the user wrote, verified by code

lead-authority defines lead.json (machine scope, mode 0600) created only by a
user-typed action (/lead in a TUI, or skein lead set run via the user's own shell —
in Claude Code, the ! prefix). A model-callable tool can read it and can request
that the user issue one; it cannot write it. This is the line that keeps the way-of-
working rule against permission laundering intact: authority still never originates in a
peer message or a model's tool call.

Verification is mechanical and local. For opencode receivers it happens in code before
the message is rendered (the sender's authenticated socket → registry → session id,
compared with the grant). For Claude Code receivers it is one command the session's
instructions tell it to run (skein lead verify --from <address>), whose output is
GRANTED/DENIED and a scope, so the model never judges trust, it reads a result.

D2. Scope, not blanket obedience

A grant carries scopes: assign (give me work from the specs), sync (rebase, merge,
report status), reprioritise, decide (answer a blocker). It never carries tool
permissions, secrets, or anything on the policy never-list. The receiver's own permission
rules still apply to every action. "Follow the lead" means "treat its directive as the
user's instruction for planning and ordering", not "act with extra rights".

No transitive trust: a directive is honoured only from the lead's own socket. A member
relaying "the lead says X" is a peer message like any other.

D3. The escalation ladder (escalate-before-idle)

blocked(item)
  L0  decide from the spec/proposal; write the decision into tasks.md notes      (self)
  L1  ask the owner peer ONCE (request, with deadline); continue ANOTHER item     (peer)
  L2  deadline passed, no reply: request the lead ONCE                            (lead)
  L3  no lead or no answer: write .skein/blocker.md (needs: team|human), move on  (board)
  L4  only `needs: human` is shown to the human — as a pending decision on the
      board and in the lead's brief, never as a stopped session                   (human)

Properties: every rung sends at most once per (item, rung); every rung ends with the
member doing something else, never waiting; human is reserved for goal ambiguity,
credentials, irreversible or never-listed actions.

D4. Done is an event (loop-done-handoff)

done runs a pipeline instead of ending the run: verify evidence → review-on-done →
record verdict → notify lead (one notify) → release claim → pick next → if none,
idle-watch with backoff (woken by inbox, board change, new change). Terminal states
remain for cancel, error and an explicit operator stop, plus a bounded prompt-mode
opt-out (--once). A completion token is a claim; for spec-backed work the evidence is
checkboxes + gate results.

D5. Standing publish authority (standing-publish-authority)

A per-repo, schema-validated policy file is the durable "explicit instruction for that
action". It is parsed with a closed schema and fails closed at load: a wrong type, an
unknown key or a visibility that disagrees with the forge disables every publishing grant
and says why. The never-list (force-push, history rewrite, visibility change, tags and
releases, other remotes, credential changes) is not overridable by the file. Rendered
three ways from one source: prompt text (replaces "never commit unless asked" with the
grant, scoped), permission rules (derived allow/deny), and a Claude Code fragment.

D6. Cross-model review on done (review-on-done)

Trigger on done; review the named commit range; reviewer chosen to differ from the author
(harness, else model family), via the same routing as crew work; token verdict recorded as
.skein/review.json keyed by the reviewed SHA; merge policy requires an APPROVE for the
head SHA. Rounds are bounded (3) and then escalate to the lead through the ladder.

Deployment shape (supersedes the earlier "Skein side" plan)

one project server per repo  =  the supervisor
  agents  = sessions + durable loops owned by the server (headless, or with a TUI/CLI attached)
  coordinator = tick module in the server (gates, rules, nudges, claims, spawn)
  lead    = any session with a lead grant: an in-server agent or a Claude Code session over A2A
human attaches to any agent, or talks to the lead only

Absorbed from skein: stage gates with evidence, stall rules, nudge dedupe/backoff/budget,
claim reaping, spawn, pending decisions. Dropped: the Go runner as default worker, the fleet
YAML as presence source (kept at most as spawn templates). Optional: A2A interop with a
running Go skein, which sees opencode-skein sessions as ordinary peers.

The one-supervisor shape also removes workarounds that exist only because sessions live in
separate processes (claims-by-DB-only, one-queue-per-directory refusal, foreign-turn guard,
per-process reservations); crew-loop keeps its claims table, which stays the durable record,
but its mutual-exclusion code becomes simpler.

Why not make the conductor an LLM

The post-mortem of the first skein is explicit: coordination in a resident process with
its own agency failed for days unnoticed. The conductor's whole vocabulary stays "read
artifacts, send one peer message, write one artifact, raise one pending decision".
Anything needing judgement goes to the lead, which is what the lead is for.
