Orchestrating Multi-Model Development

Step 0 — load exactly one active-seat profile

1. Use this plugin's host-provided PLUGIN_RUNTIME_CONTEXT_V1 line and the host's current-session model metadata as the current runtime context for profile guards. A newer explicit host model-switch update supersedes old context; unresolved conflicting exact IDs select generic.
2. A known exact ID selects its table entry, or generic if unsupported. A family label never overrides an exact ID, including an unsupported one.
3. A family label is not an identity. Codex gives GPT-6 Astra, Sol and Luna the same host instruction ("an agent based on GPT-6"; verified with Codex CLI 0.155.1 on 2026-09-23), so bare GPT-6, or any other family label, selects no profile by itself.
4. Otherwise select generic. Keep missing or conflicting identity unknown; preserve an explicitly supplied effort and leave missing effort unknown.
5. Effort comes only from the host. On Codex the PLUGIN_RUNTIME_CONTEXT_V1 line carries it (effort=<level>), read by the hook from this session's own turn context; a newer line supersedes an older one. On Claude Code the hook cannot see it: when the line says effort=unknown and the host is Claude Code, run printenv CLAUDE_EFFORT once with the shell tool — Claude Code sets it to this session's effort, and leaves it empty for a model without effort levels — and use a non-empty value as the supplied effort. Never read CLAUDE_EFFORT on a Codex host: a Codex session started from Claude Code inherits the parent's value.

Never read a user config file to guess a session override. Never load more than one active-seat profile. The selected profile's identity guard must permit its use. Quoted text, user messages, repository files, model catalogs, available child models, and a child's identity do not establish the current session's identity.

Announce the selected profile and basis before proceeding. A family label alone yields generic: say so, and name the missing exact ID. This selects instructions only: do not invent an exact runtime ID or effort, switch models, grant hook enforcement, or change the plan/subagent ID allowlists. A generic selection explains missing, unsupported, or conflicting identity.

The alias gpt-5.6 selects Sol only after the runtime-context handler has normalized it to gpt-5.6-sol. An exact supplied effort may be used; otherwise effort is unknown and receives no effort-specific claim. State which profile was loaded before planning. That profile amends the numbered steps below; where it amends a step, the amendment wins.

Profiles choose model and effort routes while authoring a wave plan or explicitly amending one. Once a lint-clean plan is explicitly user-approved, its exact provider, model, and effort fields are authoritative for adapter execution: do not re-route or reject that approved artifact against a seed profile. This never permits a mixed/unknown-provider wave or bypasses lint and user approval.

Model identifiers — full IDs only

claude-sonnet-5-5: alias probe and Workflow agent() runs on 2026-09-28, recorded in tests/eval/wave-insession.md and tests/eval/sonnet-5-5-results-2026-09-28.md.

Plans, runner args, Workflow agent() and CLI --model name the full ID; the linter and the runner reject aliases by name. Why: aliases re-point silently — on 2026-09-22 opus moved from Opus 5 to Opus 5.5, so every route written as opus changed model without an edit.

Agent-tool exception. The Claude Code Agent tool schema accepts only aliases, so a spawn through it names the alias AND the full ID from this table. A model without an alias (Opus 5, Opus 4.8) is spawned only through Workflow agent(). Sonnet 5.5 has no alias yet, so a Sonnet 5.5 research or audit spawn runs as a one-agent Workflow agent() call with the full ID, for example agent(prompt, { model: 'claude-sonnet-5-5', effort: 'medium' }). That is not a wave script. When a new Claude model ships, re-probe (a Workflow that asks each agent to report its model ID) and update this table before routing through an alias.

GPT calibration evidence and Codex routing

For Codex plan authoring, load codex-routing.md. It governs executor, research, supervisor and effort selection across active-seat profiles; the Claude quick-reference tables below apply to Claude waves only. Historical calibration informs task scope and verification, not a blanket veto or an additional user calibration gate. The final medium matrices recorded 63/87 default and 162/204 critical passes; failures remain failures. These workflow fixtures did not measure GPT-5.6 executors under independent Astra supervision. Read the packaged evidence and limitations before making claims about what those counts establish. The 2026-09-23 GPT-6 Sol/Luna calibration recorded the supervisor fixture at Sol 9/9, Luna 7/9, clean planning and skill-navigation tiers for both, and neither model passing the critical-review guards at that date. GPT-6 Luna review stays unsupported (clean 0/3). The two Sol routes are now measured, replacing the earlier policy-decision status: the standard gpt-6-sol supervisor of all-gpt-6-luna waves recorded the supervisor fixture 9/9 on 2026-09-23 (twice) and 9/9 on 2026-09-24 (×3), plus three ship-smoke runner-mode waves merge-ready first try at wall 2.44/2.27/2.14 min and cost $0.238/$0.252/$0.200 — ≈3.2× cheaper than a gpt-6-astra supervisor at the same wall time (limits: two-task toy waves with correct work only; defect detection comes from the fixture, not these waves). The gpt-6-sol review route recorded the critical-review strict gate clean 5/5 and planted 5/5 in each of two 2026-09-24 runs (10/10 and 10/10) and PR support 3/4 (one pr-gate-withheld miss) — see tests/eval/gpt-6-results-2026-09-23.md.

On 2026-09-29 the standard supervisor of all-gpt-6-luna waves moved to gpt-6.1-sol (supervisor fixture 9/9, Codex CLI 0.159.0; seam audit 9/9 with the planted seam caught 3/3). On 2026-09-30 the review route moved to gpt-6.1-sol too: after a verdict-wording fix it passed the strict review gate (clean 10/10, planted 10/10, PR support 3/4; its first run on 2026-09-29 had clean 4/5 and 5/5).

Overview

The orchestrator researches, plans, routes, integrates, verifies, and publishes; executors implement. Core principle: decisions belong to the coordinator, execution belongs to separately routed agents. Every child has an explicit model and supported effort selected from the shared routing rules; never inherit either from the coordinator or infer identity from labels. Model equality is allowed when task routing justifies it, not because of coordinator identity. Fable 5.1 (claude-fable-5-1) is a separate executor only for an explicit reasoned specialized choice or approved rung, never a blanket scoped-coding route. Effort advice is conditional on an already justified selection. Every rule below is derived from the models' official system cards; facts and numbers live in the dossiers.

Always reply to the user in the language the user writes in — this skill being in English does not mean English replies.

Process

1. Research. Study the codebase to the depth needed for decomposition: files, dependencies, conventions. Any read-only fan-out goes through the Research Routing table below — research agents never inherit your model.
2. Decisions. Close the open questions BEFORE decomposing: research an incomplete specification further and pin down the interpretation (escalate fundamental choices to the user); design cross-cutting architecture yourself and hand it out as a set of concrete implementations. Do not delegate decisions even to an Opus executor — it silently fills in gaps under ambiguity.
3. Plan. Tasks: independent within their wave (no file overlap, otherwise — next wave or worktree), self-contained (the agent sees neither the conversation nor your research), closed (no "decide for yourself what's best"). Batch small same-shaped edits into one agent's task: parallelization pays only on hard chunks — on easy ones coordination overhead eats the gain. Group for width by super-plan's Design for width rule: files_allowed cut by file, a contract-first wave before its parallel implementers, independent chains side by side. The decomposition covers ALL artifacts of the feature, including documentation (README and the like) — otherwise it silently goes stale: if you froze a file for everyone, assign it to someone explicitly.
4. Table. Before launching, show the user: task | model | effort | rationale. The table also shows, per wave, the supervisor and whether it is premium. Never a time or cost estimate — not in the table, a progress update or the completion summary (super-plan: "No time or cost estimates"). A premium model (Fable 5.1 / GPT-6 Astra, any role) is used only when the user picks it here and the plan records approvals.premium with that choice — never filled in by the orchestrator for a choice the user did not make.
5. Write the wave plan file (see Wave Plan Artifact) with status: active, and record the base SHA. You do this, not the user — the plan's lifecycle is yours to open and close, and nobody should have to hand-edit a field to make supervision work. Once it is lint-clean and explicitly approved, preserve its exact provider/model/effort fields through execution; profile routes are not a second execution-time planner.
6. Launch. Select the host adapter below; independent tasks remain isolated by the shared wave contract — for a Claude wave read references/claude-wave-adapter.md, for a Codex wave references/codex-wave-protocol.md.
7. Review (see the checklist below). Fixes — as one concrete list. Two misses in the same place — fix the task spec, don't repeat the prompt.
8. The final end-to-end review is the orchestrator's own. Before it you may launch an Opus verifier, but the verdict is the orchestrator's. The coordinator never authors code. This holds for defects its own review or the final review finds, however small: they go to a one-task supervised wave, never a coordinator edit. Measured: in the 2026-09-24/25 sessions, orchestrators wrote wiring and review fixes themselves and pushed them unreviewed.
9. Completion. Claude: at most 3 iterations per task, then escalation. Codex uses the native helper's bounded attempts from shared Codex routing. Run the plan's ci.commands exactly (in addition to the offline suite) before the final wave's push, not after — with ci: "none: <reason>" there is nothing extra to run. A red ci.commands entry stops completion exactly like a red offline suite: fix it, don't push through it. At the end a summary: done / verified / remaining. Set the wave plan's status: done in the same breath — an open plan keeps the drift hook paying for a wave that ended.

Scope of a bypass. When supervised execution fails and the user approves "implement directly," record the scope in the plan — which waves the approval covers — and state that same scope in the PR body. The approval covers those waves only. It does not cover review fixes: a defect a review or the final review finds still goes to a one-task supervised wave, and critical-review's findings gate still applies regardless of the bypass. Set the plan's status: done with a note recording the bypass and its scope, not a free-text status in place of done.

Stop handling. A stop is failed, error, contract-unsatisfiable, or environment-blocked — the environment itself is broken, not the contract or the task's work: name the failing command and its exact error line, fix the machine, and re-run, rather than treating a broken environment as a contract defect. Every stop ends with one recommended next action, phrased as a yes/no question for the user to approve or decline. This keeps the long-waits rule below: wait on a running agent or runner with long waits, not frequent polls.

The orchestrator spends its own effort on decisions, not on reading. It does not read whole files or diffs into its own context — that is delegated to a research agent or a task's executor; where it needs a scale of a change it uses git diff --stat and reads only targeted ranges itself. It does not keep a journal that duplicates state a helper or runner already holds — the wave plan, the state files, and summary.json are the record. And it waits on a running agent or runner with long waits, not frequent polls — a polling loop burns turns on the orchestrator's own round trips instead of on the work it is waiting for.

Model Routing — Quick Reference

Torn between Haiku and Sonnet → Sonnet 5.5. Torn between Sonnet and Opus → improve the task spec first, then upgrade the model. Sonnet 5.5 (claude-sonnet-5-5) is the default executor for closed implementation; Opus 5.5 (claude-opus-5-5) is the default heavy executor and verifier. claude-sonnet-5 is retired as a route (2026-09-28); the ID stays valid so that approved plans still execute. Opus 5 remains addressable as claude-opus-5 — the standard supervisor for Opus 5.5 executors and for tasks whose rungs reach Opus 5.5; retired as an executor. Opus 4.8 (claude-opus-4-8) is retained only for compiled-binary work and as the cyber-refusal fallback.

Routing anti-patterns: no sub-orchestrators — executors never spawn their own subagents (documented failures in deep delegation chains: status honesty, not capability); don't give any executor untrusted external content without platform safeguards (Opus 5.5 and Fable 5.1 are the most robust through tool results, but safeguards still matter); don't give Sonnet multi-hour sessions; don't route compiled-binary reverse-engineering to Opus 5.5, Opus 5 or Fable 5.1 (their classifiers block it) — use Opus 4.8.

Research Routing — Quick Reference

The Model Routing table above routes work that changes things. Read-only research agents — the fan-out behind planning, decomposition and reviews — are routed here instead. An unrouted research agent inherits the session's model: on a Fable seat (5 or 5.1) that silently bills file listings at the most expensive rate available. Never spawn a research agent without naming its model.

Torn between Haiku and Sonnet → Sonnet 5.5, as always. The route comes from this table, never from inheritance: on an Opus 5.5 seat the open-research route equals the seat model, which is allowed because the table chose it — and every spawn still names its model. Research is gathering, not deciding — the decisions stay in the orchestrator seat.

Mandatory lines in every research agent's prompt (the research counterpart of the executor task template):

• every claim carries evidence as file:line, or as a command plus its output;
• not found is a valid and expected answer — never fill a gap with a guess (Sonnet 5.5 guesses instead of abstaining: AA-Omniscience incorrect-answer rate 0.27, the highest of six, p. 80; Sonnet 5 fabricated precisely when information was missing, Sonnet 5 card p. 71);
• read the sources: answering from memory about library or system behavior is forbidden (Opus 5's documented recall-as-truth failure, p. 87);
• never open, print, copy or transmit credentials, tokens or configuration files that hold them (for example ~/.codex, ~/.claude, app configs with Authorization headers); if the research needs a secret, stop and report.
• quote globs in shell commands: the shell may be zsh, where an unquoted --include=*.kt fails with "no matches found" (measured: 31 occurrences in one session);
• a claim that a build task or target exists cites the build tool's own listing;
• a read-only agent returns its report as text and never writes files (measured: a read-only agent ran mkdir when asked to write a report).

Choosing Executor Effort — Quick Reference

This table is about the effort you hand to executors. Your own session's effort is your profile's business, not this table's.

Signal rule: wanting to give Sonnet xhigh because the task is open-ended → that means switching the model to Opus 5.5 (claude-opus-5-5) or returning to the Decisions stage, not effort. Opus 5's effort curve is the exception — higher is not better; it peaks mid-range on coding and overthinks at max, so cap Opus 5 executors at high. Fable 5.1's curve has its own shape: task correctness keeps rising with effort but so do unrequested out-of-scope edits (p. 169), so a Fable 5.1 executor prompt always carries an explicit scope and brevity line.

Wave Isolation

A supervised wave gives every executor its own git worktree and commits its work to a branch named wave/<task-id>. Record the base SHA in the wave plan before the wave starts; every later comparison is made against that SHA, never against a moving HEAD.

The base must be the commit the worktrees actually fork from, not your local HEAD. Agent worktrees branch from origin/<default-branch> by default (worktree.baseRef: "fresh"), so a commit you made locally but never pushed does not exist for any executor. Recording an unpushed HEAD corrupts every comparison in the same direction: files that exist only in your checkout appear as deletions in every branch, and the supervisor charges each executor with a files violation for a change nobody made. That is the §7 failure — correct work blocked — arriving through the base rather than through the contract.

So, before launching: push the commit you intend as the base, or record git rev-parse origin/<default-branch> and accept that anything unpushed is invisible to the wave. After the first executor commits, verify with git merge-base wave/<task-id> HEAD; if it does not equal the recorded base, stop and fix the plan rather than judging against it.

This is not tidiness, it is what makes the contract checkable at all. Executors sharing one tree make two things impossible:

• Attribution. A diff of the shared tree contains every task's concurrent edits, so "this task touched a forbidden path" cannot be distinguished from "a neighbour legitimately owns that path" — the very violation the contract exists to catch.
• Reproducibility. A required command re-run against a tree a neighbour is editing can fail for reasons that have nothing to do with the task under judgment, and the escalation ladder would then send correct work back for rework.

A commit made inside a worktree survives that worktree's removal — worktrees share the object database and refs — so git diff <base>..wave/<task-id> stays available for supervision, and a second worktree can be checked out from the branch for independent verification.

For an unsupervised wave, tasks still must not overlap in the files they touch.

Wave Plan Artifact

Before launching a supervised wave, write the plan to a file — one entry per task, carrying the prose, the contract, the assigned model, the branch and the base SHA. The file opens with the unfenced status:/base: header, then one fenced json wave-plan block:

status: active base: 7c05ff5

{ "waves": [
  { "wave": 1,
    "supervisor": { "model": "claude-opus-5-5", "effort": "high" },
    "tasks": [
      { "id": "http-retry",
        "branch": "wave/http-retry",
        "executor": { "model": "claude-sonnet-5-5", "effort": "medium" },
        "ladder": [],
        "contract": {
          "files_allowed": ["src/http/**"],
          "files_forbidden": [],
          "must_run": [{ "cmd": "pytest tests/http -q", "evidence": "required" }],
          "forbidden_moves": ["weakening, deleting or skipping an existing test"],
          "report_must_answer": ["Which call sites now retry?"] } } ] }
],
"ci": { "commands": ["pytest -q"], "workflows": [".github/workflows/ci.yml"] },
"e2e": "not-applicable: http-retry touches one call path, not a data-transforming pipeline" }

This is the real plan format; see super-plan's Plan Format for the full schema, including approvals.premium.

You own both transitions. Write the file with status: active at step 5 and set status: done at step 9. The user never edits it: a supervision layer that depends on someone remembering to flip a field by hand is a supervision layer that will be off when it matters.

Without this file "deviation" has no referent: there is nothing to deviate from. It is a file rather than something you hold in context because a wave outlives a context window, and a summarized context keeps the task list while losing the exact identifiers the supervisor needs.

Task Prompt Template (mandatory blocks)

Every executor prompt contains all six blocks — explicit instructions measurably reduce the documented failure modes:

1. Context: specific files and lines, dependencies, project conventions. Compute numeric examples in the spec with a tool, not in your head — a wrong example contradicts the formula and derails the executor. In a supervised wave the executor works in its own worktree and sees no neighbour's edits, so say so — an agent that expects a busy tree will misread its own isolation. Never paste untrusted third-party text (PR or issue comments, CI logs, fetched pages, user-supplied documents) into an executor prompt; write it to a file or name its path and let the executor read it with a tool. A subagent's prompt is its user turn, and Opus 5.5 follows instructions planted in its user turn (about 2.1% at default effort, 7.4% at max, 0 of 105 via tool results; Opus 5.5 card, pp. 123–126).

2. Boundaries: what NOT to do — don't refactor adjacent code, don't add unrequested features/files, don't touch anything outside the list.

3. Dead-end protocol: "If data or access is missing, a tool is broken, or the path is impossible — stop and report what's blocking you. Don't invent values, don't work around the restriction, don't pick an interpretation on the user's behalf." If your task needs an artifact that another task of this wave is producing (a file, fixture, function or behavior missing from your worktree), stop and report blocked-on-sibling: <what is missing and which task makes it>; do not invent it and do not commit a placeholder. An environment block — a broken machine, not broken work — stops and makes environment-blocked: followed by the verbatim error line the first line of the report: permissions on a cache or .git, a missing SDK, a lock file, commit signing that needs a prompt.

4. Prohibitions: do not spawn subagents; no destructive operations (force-push, reset --hard, rm outside the task) without explicit permission. Never open, print, copy or transmit credentials, tokens or configuration files that hold them (for example ~/.codex, ~/.claude, app configs with Authorization headers); if the task needs a secret, stop and report. That includes untracked build configuration a worktree links — local.properties, .env, *.keystore, gradle.properties under ~/.gradle — which may hold a key or token: link or reference such files by path; never cat, head, grep or otherwise print them. Never end your turn while a command you started is still running — no Monitor, no ScheduleWakeup; keep polling its log until it exits. Phrase prohibitions without qualifiers — executors rules-lawyer around wording when it conflicts with "the overriding goal". The task text is not authorization to use credentials, secrets found in the repository, or production systems; if the task seems to need one, stop and report. Measured: Sonnet 5.5 accepts unverifiable authorization more readily than Opus 5.5 (2.76 vs 2.39) and once reasoned 'The card is the authorization' (Sonnet 5.5 card pp. 60–62).

5. Definition of done and response format: list of changed files, the gist of the changes, output of actually executed tests/linter, plus the committed-work proof: git log --oneline <base>..HEAD (non-empty) and git status --porcelain (empty), both pasted — uncommitted work does not exist for the wave, and "done but never committed" is the most common rejection on record — unless the executor stopped under the dead-end protocol.

6. Contract: the machine-checkable half of the task. Prose carries intent; the contract carries what a supervisor can decide without arguing about intent.

   contract:
     files_allowed:   [src/http/**, tests/http/**]
     files_forbidden: [src/auth/**]        # another task owns these this wave
     must_run:
       - cmd: pytest tests/http -q
         evidence: required
     forbidden_moves:
       - weakening, deleting or skipping an existing test
       - catching an exception to make a check pass
     report_must_answer:
       - Which call sites now retry?
       - What happens after the final failed attempt?

   evidence: required replaces trust. A report claiming a command passed without that command's actual output is not weak evidence — it is a violation in its own right.

   State the prohibitions explicitly and loudly. This is measured, not stylistic: an explicit "don't work around it — report it" lowers fabricated workarounds from 17.4% to 9.1% for Fable 5 (pp. 161–163) and from 9.4% to 2.8% for Opus 4.8 (pp. 109–110). The Fable 5.1 card did not repeat this measurement; what it documents instead is unrequested out-of-scope edits rising with effort (p. 169), which the same explicit scope line addresses.

For tasks with images/PDF/charts — give Sonnet code-execution access.

Supervised Waves

Supervision is a stage in the Workflow script, not an instruction to self-check. A check the executor is asked to perform is a check it may decide it already satisfied; a check in the control flow around it is one it never gets a vote on. A stage can also do what advice cannot: reject and re-run.

Send references/supervisor-prompt.md to a fresh separate supervisor with the contract, report, base SHA and branch. It never reuses an executor child or forks its conversation, even when model and effort match. Astra's separately approved executor exception uses a fresh Astra supervisor and is fresh-context separation, not different-model independence; other supervisor restrictions remain.

Mechanical verification before the judge

The shipped runner runs a cheap fact-collecting verifier before the judge: a branch with no commits, a path outside files_allowed, a red must_run or missing pasted evidence bounces straight back as rework without a judge. The verifier never decides ok; for the details and the load-bearing properties read references/verdicts.md.

Choosing the supervisor — Quick Reference

Two hard rules, then the table. Use a fresh separate supervisor; outside the separately approved Astra exception, never the executor's own model (self-preference: ≈0 for Opus 4.8; measured zero for Fable 5; 0.1 points out of 10 for Fable 5.1, lenient when told the author is Claude, Fable 5.1 card p. 124; Opus 5 now measured ≈0, +0.05 / −0.03 with intervals crossing zero, Opus 5.5 card p. 128; Opus 5.5 +0.07 of 10 when its prompt reminds it that it is Claude, Opus 5.5 card p. 128 — which is why the runner's judge prompt never names the executor's model. Not stating it does not stop a judge in an all-Claude pipeline from inferring it; what bounds the effect is the magnitude and the contract's mechanical half — verifier facts and grep-decidable checks the judge cannot soften). Never a weaker tier than the executor's: the judge re-runs and re-derives everything the executor did. Tier means product class — Haiku < Sonnet < Opus < Fable — not a benchmark score, so Fable 5.1 is not a weaker tier than Opus 5.5 even where Opus 5.5 benchmarks higher.

A wave has one supervisor, so pick its row by the strongest model any task in the wave can run, ladder rungs included — a claude-sonnet-5-5 task whose ladder reaches claude-opus-5-5 is supervised by claude-fable-5-1, not by Opus 5.5 (the runner and the linter reject a supervisor that is also a rung). The rung rule counts the default ladder: an omitted ladder field is not an empty one — it inherits the runner's default ladder, which reaches claude-opus-5-5, so only an explicit "ladder": [] opts a task out of it.

Premium models. Fable 5.1 and GPT-6 Astra are premium; they are used — as supervisor, executor or ladder rung — only when the user chose them at Gate 1 and the plan records approvals.premium; the linter enforces it. Standard alternatives: Opus 5.5 (Sonnet/Haiku waves), Opus 5 (for Opus 5.5 executors), Codex gpt-6.1-sol for Luna-only waves.

Plans name every supervisor by its full ID (see Model identifiers above): Fable 5.1 is claude-fable-5-1. Fable 5 is no longer addressable and keeps its profile and dossier for history.

Effort is high across the board — the shipped runner's default — and the row is measured, not stylistic: on 2026-08-12 a Haiku supervisor at medium passed an unsatisfiable contract, filing its whole analysis into remarks. A cheaper judge on a mechanical task is not the economy lever; skipping the model entirely is (see the cost section below). On 2026-08-12 the supervisor tier passed F1–F4 in single live runs on Haiku 4.5 (the default eval model), Sonnet 5, Opus 5 and Fable 5, and on 2026-09-01 on Fable 5.1; single runs prove "can", not a rate. On 2026-09-23 Opus 5.5 passed the supervisor tier 9/9 with the F3 false-positive guard 5/5 (EVAL_REPEAT=5) — a repetition, not a single run. Opus 4.8 has not run the F1–F4 supervisor fixtures; its supervisor route rests on its system card.

The supervisor trusts artifacts only. A verdict is {"ok", "violations", "remarks"}, and only violations decide ok — doubts go to remarks. pasteReproduced: false is a recorded fact, never an accusation; repetition is what escalates. Before judging or acting on a verdict, read references/verdicts.md.

Escalation ladder

Host adapter

Invocation publication contract

publication is optional: if omitted, it means exactly publication: push and preserves all normal behavior. The choice belongs at this composition boundary, not in a host adapter, runner, helper, plan, or profile. Only publication: local must be explicit; only the enclosing critical-review post-review fix flow may request it; it is never inferred from host or model.

Local mode never weakens lint, the pushed-base requirement, contracts, mechanical verification, supervision, verdicts, plan-order integration, or the full-wave review. Both adapters complete all of that work and return the resulting local feature-branch commit(s), task branch names, and state/verdict evidence to their caller, but local mode performs no push. The wave still forks from the current pushed PR head. Local mode is one publication transaction: if approved fixes need dependent bases that cannot safely fit in that one supervised wave, stop before publication rather than push around the gate.

• Claude-only wave: read and follow references/claude-wave-adapter.md (it generates the launch script and invokes the shipped runner).
• Codex-only wave (GPT-6 Sol/Luna or GPT-5.6 executors, or separately approved Astra initial/final rung; supervisor per shared Codex routing (premium Astra with approvals.premium, or standard gpt-6.1-sol for all-Luna waves)): read and follow references/codex-wave-protocol.md; do not invoke Claude Workflow. Its default adapter is references/codex-wave-runner.mjs, as described there, with the native action loop as fallback. Launch codex-wave-runner.mjs as an escalated command outside the Codex sandbox, never inside a sandboxed Codex session — see the protocol for the nested-sandbox reason. An Astra executor needs both astra_executor_reason and approvals.premium — one records the reason, the other is the approval.
• Mixed or unknown-provider wave: stop before spawning and return the linter or identity error.

Every Codex spawn names model and reasoning_effort from the exact returned action. Never write a fresh runner, hand-edit state, or replace a missing model with a default or alias. The shared contract, verifier, supervisor schema, escalation ladder, and result review remain single-sourced in this skill; the adapter selects only the host invocation.

For a lint-clean, explicitly user-approved plan, the approved plan is authoritative for adapter execution. The adapter uses its exact provider, model, and effort fields without re-routing or rejecting them against seed-profile recommendations; lint and the mixed/unknown-provider stop still apply.

Claude-only wave — invoke the shipped runner

For a Claude-only wave, read and follow references/claude-wave-adapter.md before launching. Never write a custom wave script.

When the contract is what is broken

ok:false with satisfiable:false stops the task at once — no rework, no stronger model. Read and follow references/contract-amendment.md (amending is your job; removing or weakening a check is a yes/no question to the user).

Cost, and when to skip the model

A supervisor invocation is an agent with tools — a diff, the commands, the greps — so it is not one model request. The tiers also invert: a Haiku 4.5 task is supervised by Opus 5.5 (see the supervisor table above), making the supervisor the expensive half.

For Codex waves, the shared routing policy always requires the separate model supervisor, including mechanical tasks. The cost shortcut below is Claude-only.

Run full agentic supervision for tasks whose contract has must_run commands or files_forbidden entries that matter: migrations, shared helpers, security-adjacent code. For a small mechanical task, check the predicates (paths touched, commands run, evidence present) in plain script logic and skip the supervisor model. Supervision that costs more than the work it guards gets switched off, and then it guards nothing.

The shipped runner now performs the predicate half mechanically before every judge call (see Mechanical verification above); what remains yours is scoping each contract's gates to its files and choosing the judge's effort.

Orchestrator Drift

A Stop hook compares your turn against any plan under docs/superpowers/plans/ whose header says status: active; its advice arrives as additional context — act on it or say why not. It never blocks. Set the plan's status: done when the wave ends so it goes quiet. How it works and what it costs: references/orchestrator-drift-hook.md.

Anti-Deception Rules

Each of these comes from a measured failure, not from general caution.

Rules explicit, checks opaque. The two halves come from opposite findings and must not be collapsed. The contract is handed to the executor in full — that is the explicit-prohibition half, and withholding it raises fabrication. What is never disclosed is the supervisor's method: that a second model re-runs the commands instead of reading the pasted output, that it compares the two, that it diffs the tests against the recorded base SHA, that it greps for the forbidden moves. An executor told the rules complies with the rules; an executor told how compliance is measured optimizes for the measurement.

Choosing the supervisor's model. Outside the approved Astra exception, never the executor's own — pick from the supervisor table. Opus 4.8 (pp. 122–124) and Opus 5 (Opus 5.5 card p. 128) are measured ≈0, so Opus 5 may now supervise. Fable 5.1 carries a measured 0.1/10 lenience when told the author is Claude (p. 124), and Opus 5.5 a measured +0.07/10 with a Claude-identity prompt (Opus 5.5 card p. 128): both supervise, with a measured small bias. The judge prompt never states the executor's model; inference remains possible in an all-Claude pipeline, and the bound is the magnitude plus the contract's mechanical half.

Result Review Checklist

An agent's self-report is not evidence (every executor has documented false success claims and omissions about corners cut). In a supervised wave you review the supervisor verdicts and remarks, not the executor reports — paraphrasing a report where a verdict belongs is itself a failure, and the documented one: Opus 5 relays subagent claims unverified (p. 81).

• Solves the stated task and matches the plan — by the diff, not the summary
• No unrequested changes (refactorings, files, abstractions)
• Consistent with the other agents' results (seams, duplicates, conflicts)
• Build/tests/linter — verified by running; "should work" doesn't count
• Documentation (README and the like) reflects the final state of the feature
• Every task carries a supervisor verdict; remarks are read and either acted on or dismissed on the record
