OpenCode Runtime Notes

This skill is installed as an OpenCode-native SKILL.md. For runtime-backed helpers, prefer the shared ai-agents-skills runtime root and the AAS_RUNTIME_ROOT override instead of assuming a Codex-specific runtime path.

Autonomous Research Loop

Use this skill to run research autonomously while preserving bounded scope, evidence, recovery state, and explicit stop conditions. It is an orchestration contract, not an instruction to run indefinitely.

Core Rule

Every autonomous loop must have:

1. A concrete goal.
2. Success criteria.
3. Hard budgets.
4. A loop ledger.
5. Evidence gates.
6. Recovery notes.
7. Stop conditions.

If any of those are missing, create them before starting the first autonomous iteration.

When To Use

Use this skill for:

• Continuing nontrivial research across multiple iterations.
• Running source discovery, synthesis, verification, and revision without asking after every step.
• Coordinating bounded subagent research or panel review.
• Integrating autonomous behavior into an existing research workflow.
• Resuming a research loop after interruption or context compaction.

Do not use it for:

• Trivial one-shot lookups.
• User requests that explicitly ask only for a plan or analysis.
• User requests that ask only to investigate, diagnose, review, audit, verify, or report, unless the user also explicitly asks for autonomous follow-on work.
• Work that lacks a safe budget or stop condition.
• Blind command execution without inspectable evidence.

Required Loop Files

For a research workspace, keep these files in the active research directory:

• loop_state.json: goal, success criteria, mode, stop flags, current status.
• budget.json: iteration, wall-clock, token, cost, depth, and child-agent limits.
• iterations.jsonl: append-only record of each loop iteration.
• recovery.md: latest resume point, blockers, next safe action, and evidence gaps.

These remain the base ARL ledger and compatibility surface. Goal Focus v2 adds its four authoritative strategy files described below; it does not replace the budget or append-only iteration ledger.

If a runtime helper is available, prefer the companion autonomous-research-loop-runtime skill to initialize and validate these files. If it is not available, create the files manually in the same structure.

Loop Modes

Choose the narrowest mode that can satisfy the goal:

• monitor: check whether new evidence or tasks exist, then stop if nothing changed.
• bounded-research: search, analyze, verify, and write within declared budgets.
• implementation-support: inspect code or docs, propose research-backed changes, and verify integration assumptions.
• panel-loop: use a bounded multi-agent discussion, then synthesize and verify the result.
• recovery: resume from recovery.md, validate state, and continue only from the recorded next action.

Preflight

Before starting an autonomous run:

1. State the scope and material exclusions.
2. Define success criteria in observable terms.
3. Set hard budgets:
   • maximum iterations
   • maximum wall time or user-visible turns
   • maximum child workers
   • maximum source hops or search depth
   • maximum spend or token budget when applicable
4. Define stop conditions. The enforcement policy in canonical/instructions/autonomous-loop-enforcement.md governs them: user requirements override everything, so capture them into loop_state.stop_conditions at init. When the user gave no overriding requirement, the loop stops only on:
   • the required number of loops reached
   • credit or quota exhausted, or a user-set spend cap hit
   • the stated goal fully resolved, confirmed by a machine-checkable success check
   • a user message asking to stop, pause, or switch tasks Plateau, evidence-gap, and repeated-blocker signals are not terminal under these defaults; record them, then downgrade the iteration decision to revise or delegate and continue. They end the loop only when the user set them as an explicit stop condition.
5. Initialize or validate the loop files.

The maximum iteration budget is a hard cap, not a target to exceed while searching for success. A loop may run fewer iterations when success or a true hard stop condition occurs, but it must never append more than max_iterations records. A normal early stop before the final allowed iteration is valid only when the success criteria are met and the iteration cites a machine-checkable proof/success artifact. Otherwise continue, revise, or delegate; do not mark the loop blocked early. A self-marked blocker is not a stop under the enforcement policy: record it and continue. The decision blocked is reserved for the final allowed iteration, when the budget is exhausted without success.

Iteration Protocol

Each iteration must record:

• iteration number
• timestamp
• mode
• objective
• evidence checked
• actions taken
• output produced
• remaining gaps
• budget consumed or estimated
• decision: continue, revise, delegate, stop, or blocked

Only use a continuing decision (continue, revise, or delegate) when the next iteration has a concrete objective and remaining budget. The final allowed iteration must be terminal (stop or blocked); if success criteria have not been satisfied by then, stop as budget exhausted instead of leaving the loop running. Before the final allowed iteration, stop must mean success/proof found and must cite at least one evidence id that resolves to a proof artifact, and blocked is not accepted: record the blocker and continue with revise or delegate.

Heavy computation inside iterations

Route heavy computation (exhaustive enumeration, certificate suites, censuses) through the unified broker exposed by modal-research-compute. The recommended order is local > Kaggle > Modal > Hetzner > GitHub Actions; a valid custom order keeps local first and may reorder or omit unique remote lanes, while explicit backend overrides are hard pins that still pass lane safety gates.

User-named compute resources are strict. If the user asks for specific lanes (e.g. "use Hetzner and Kaggle", "no local dual residual"), encode that on the job as policy.backends: ["kaggle", "hetzner"] (or a single policy.backend) and only use listed lanes. Do not fall back to local or other unlisted backends while any requested lane is still available; only after all requested lanes are out of credits/resources/guards may you block, defer, or ask the user — never silently expand the set. Do not bypass the broker with ad-hoc heavy local processes while an allowlist is active (see canonical/instructions/compute-offload-routing.md § User-requested compute resources).

Let the broker's adequacy and self-preservation policy decide among permitted lanes. Use run plan as the routing decision boundary. Execute a selected Kaggle or Hetzner lane through its corresponding lane skill (preflight, then Hetzner oneshot --confirm or Kaggle run --confirm); run submit dispatches only Modal/GitHub Actions. Ensure lane credentials are in the process environment before lifecycle verbs (Hetzner: HCLOUD_TOKEN in env only — never print or argv). If a strict allowlist reports all lanes exhausted, re-run same-bundle lane preflight with credentials loaded and record available/budget_verdict/reason before banking a multi-iteration infrastructure blocker; that recheck is diagnostic and does not widen the allowlist. See skills/hetzner-research-compute/references/agent-loop-integration.md. When the broker is unavailable and the user did not forbid local, use the throttled local queue defined in skills/modal-research-compute/references/local-compute-throttle.md (cross-platform: lockfile singleton, idle priority, chunked resumable checkpoints, load guards). Never launch ad-hoc unthrottled heavy processes. Record run IDs and quote runner-log lines (not agent summaries) when banking offloaded results, and treat a red run with zero artifacts as a wiring bug but a red run with FAIL rows as mathematics to investigate.

Evidence Gates

Apply the relevant gates before accepting an iteration output:

• Source claims require source IDs or file references.
• Current facts require dated source checks.
• User-facing writing requires writing-style-settings.md to be loaded before final prose. Mathematical, TCS, graph-theoretic, Lean, or LaTeX writing also requires math-manuscript-style.md.
• Early proof/success stops require an evidence id backed by a local machine-checkable proof artifact, such as proof_artifacts/<evidence_id>.json, whose checker metadata reports a passed check and whose proof file exists in the loop directory.
• Code or workflow changes require local inspection of relevant files.
• Multi-agent conclusions require synthesis that separates agreement, disagreement, assumptions, and unresolved questions.
• Recommendations must distinguish confirmed evidence from inference.
• Anti-false-consensus: do not continue review until all approve; require an evidence delta between critique rounds; force residual uncertainty on unfinished load-bearing claims; multi-LLM LGTM alone never banks (different- family result review and/or machine-checkable support required).

If a gate fails, record the failure in iterations.jsonl and choose one of:

• retry with a narrower objective
• delegate a bounded check
• revise the scope
• stop as blocked

Formal tools (optional Lean assist)

Lean formalization is opt-in via formal_policy (default off). When enabled, formal skills assist stable lemmas on a formal-track path; they are not the default discovery primary under single-path recovery.

Do not confuse headless force-driven ARL (drive unattended) with formal_policy=force (host formal hygiene tick).

Wire with:

… init --dir <loop> --goal "…" --success-criteria "…" --formal-policy on
… drive --dir <loop> --provider <p> --formal-policy on
# aggressive host hygiene (scan-first; no OpenGauss auto-spawn):
… drive … --formal-policy force --formal-force-after-iteration

Env: AAS_AUTOLOOP_FORMAL_POLICY, AAS_AUTOLOOP_FORMAL_PROJECT, AAS_AUTOLOOP_FORMAL_FORCE, AAS_AUTOLOOP_FORMAL_TYPECHECK. File: <loop>/formal/formal_policy.json or loop_state.standing_orders.formal.

When the committed path is formal-track, use positions F1–F7 from informal-to-lean-formalization-runbook (intake → Explore → skeleton → fill → optional interactive OpenGauss only → strict gate → fresh review → acceptance). Evidence labels (lean_declaration_search, opengauss_run, formal_scan, formal_typecheck) never alone set claim-support. Host force tick reports are hygiene only (claim_support_status=not_evaluated).

Default scripted force-loop (all OS; enforce + hard + notify ON): runtime pack autonomous-research-loop-runtime/force-loop/ — discovery template arl-scripted-force-loop. Thin formal-env sample for existing supervisors only: canonical/templates/sample-arl-headless-driver-with-formal/ (formal_env.inc.sh — no forked driver). Instruction: canonical/instructions/autonomous-loop-formal-policy.md.

Co-install the formal-research profile (or the individual Lean skills) for Explore / gate / skeleton tooling; serious-research alone is insufficient.

Goal Focus v2: reviewed single-path control

Current deployment status: the state/migration/review contracts and an explicit trusted-local execution profile are implemented. Set AAS_AUTOLOOP_PROVIDER_TRANSPORT=trusted-local only for operator-approved provider CLIs in a dedicated project. The runtime then applies mandatory cgroup/POSIX resource limits, timeouts, bounded output, and descendant cleanup while retaining Goal-Focus staging and independent review. Omission or strict-isolated remains fail-closed; trusted-local does not claim credential, filesystem, or network isolation from a hostile provider process.

Trusted-local is also fail-closed until each enabled provider has exact AAS_AUTOLOOP_ATTESTED_BIN_<PROVIDER>, ...SHA256_..., ...UPSTREAM_..., and ...MODEL_... pins. Resolve launcher symlinks before hashing; use upstream anthropic for Claude, openai for Codex, and deepseek for CodeWhale. Re-pin after provider updates. The runtime companion documents the optional dependency-root pin, validated AAS_AUTOLOOP_RESOURCE_* overrides, default limits, and the pre-exec cgroup/RLIMIT attestation gate.

For an open problem or long-horizon claim, use Goal Focus v2 when the runtime companion is available. It turns the main goal, obligation structure, approach portfolio, and selected next action into revisioned control state instead of letting stale campaign prose decide what runs next.

Authoritative files and projections

Goal Focus v2 has four authoritative files in the loop directory, plus a permanent negative-space ledger:

loop_state.goal, loop_state.success_criteria, loop_state.next_preferred_path, loop_state.goal_focus_projection, and the Goal Focus managed block in recovery.md are compatibility views. Reconcile them from the authoritative files; never use them to override current_plan.

Modes are:

• off: v2 does not govern dispatch; legacy behavior remains available.
• monitor: report drift and replan signals without enforcing an active-plan or review-before-bank gate. It preserves legacy dispatch/banking behavior and is observational only.
• enforce: require coherent, reviewed, unexpired state before dispatch. A pending candidate or unresolved replan trigger prevents new primary work.

New goal-focused v2 loops use enforce. Existing v1 loops do not change mode merely because the runtime is upgraded; migrate them explicitly.

Pre-dispatch selection and replanning

Before an enforce-mode primary action, the host runtime must:

1. recover any interrupted state transaction;
2. regenerate stale compatibility projections;
3. validate goal, registry, plan, ledger, and revision agreement;
4. block on a pending result review; and
5. run a structured strategy review if the plan is missing, stale, ineligible, expired, tripped, disputed, or stalled.

Strategy reviewers return strategy_advice.v1, including inspected and uninspected evidence, interval estimates, falsifiers, strongest objections, and one bounded next action. They receive the complete goal contract, registry, and current plan so they can assess switching cost and stale state against the exact bound authority. The prompt gives the incumbent no presumption or tie-break advantage; list order, active status, and sunk effort are not positive evidence. The host filters ineligible approaches and scores the rest conservatively:

+5 goal resolution +3 information gain +2 option value +1 diversity
-2 execution cost -2 verification cost -4 bridge debt
-3 dependency risk -1 correlated redundancy

Select a dominant exploitation path only when its conservative lower bound exceeds every competitor's optimistic upper bound. Otherwise choose a bounded discriminating experiment from at most three mechanism-diverse live approaches. A reviewed selection commits exactly one plan revision, and every direction commit—including retention or a campaign/approach switch—requires a genuinely different-family review. The strategy review is bound to the complete goal/registry/plan objects, their semantic fingerprints, and their exact source hashes; even a same-revision mutation invalidates the commit.

The guarantee is “best-supported registered direction under the current evidence, budget, and policy,” not “objectively best direction.” Panel votes are advice, not mathematical evidence.

Stage, independently review, then finalize

A provider exit does not bank a research result. In enforce mode the primary proposes one iteration record, and the runtime stages it as iteration_candidate.json, pinned to the dispatched plan_revision.

Before launch, the host writes iteration_dispatch.json, binding the candidate id, known executor family, and canonical full-object fingerprints/revisions of the plan, goal contract, and approach registry. Enforce-mode staging requires and atomically consumes that exact live intent. A driver-family failover forces fresh strategy review; --cmd, provider command/argument/binary overrides, and unverified routing gateways are not valid enforce-mode primaries. Standard model/reasoning pins remain supported. If a host dies before staging, inspect the in-flight id with goal-focus recover-dispatch and cancel it only after the original worker is confirmed gone.

If a provider directly staged a candidate but the host completion gate later failed (including timeout, capture/output rejection, or cleanup failure), the runtime moves it behind a fixed quarantine marker and the supervisor stops without review, banking, retry, or failover. Inspect with goal-focus recover-quarantine --dir <loop> and release only with the exact reported candidate fingerprint; the released quarantine is retained under .goal_focus/quarantined_candidates/ for audit.

The host then requests a strict result_review.v1 from a provider family different from the primary executor. CodeWhale and DeepSeek are the same family for this gate and are launched with an explicit DeepSeek upstream pin; Codex ignores configurable provider defaults and pins the OpenAI provider. Kimi, unknown routes, and multi-family gateways are unverified until the host can attest their resolved upstream family. Every material staged result needs a unique claim id and safe loop-relative evidence path. The host no-follow reads and size-bounds each regular UTF-8 artifact, then embeds its complete content, path, size, and digest in the immutable candidate; an identifier by itself is not evidence. Every review binds the canonical hash of the complete candidate. A passing review must identify inspected paths, support every banked claim using matching staged evidence that it actually inspected, accept each exact proposed obligation target with at least one matching staged evidence id, and contain no failed machine check. Every passing reviewer must cover the complete exact claim and obligation set; disjoint partial coverage cannot be combined into a pass. If review is unavailable, leave the candidate pending without charging a finalized-attempt budget, and launch no new primary iteration. Only a substantive failed/rejected review finalizes rejected work.

Finalization is one recoverable compare-and-swap transaction: append the final ledger row, update control and budget post-images, archive the candidate, and remove the pending file. Interrupted transactions are recovered idempotently; candidate or same-revision authority mutation fails rather than merging incompatible inputs.

Trusted-local real panels are available only through the explicit transport opt-in described above. Their provider-native prompt-only flags disable shell, filesystem, MCP, browser, memory, custom-instruction, and subagent tools, while the host applies executable attestation, resource limits, bounded capture, and review-schema validation. This profile still trusts the local CLI and its host view. The stronger strict-isolated design additionally requires an allowlisted runtime/provider filesystem, immutable interpreter closure, credential blindness, and endpoint-constrained egress; because that complete boundary is not yet implemented, strict-isolated/default real panels fail closed before spawn. Injected runners remain available only for offline contract tests.

Rejected work remains auditable: its real iteration, token, and USD deltas count against budget, while its duration, executor, and compute provenance remain on the rejected ledger row. It banks no claim, clears obligation transitions, records campaign_delta: none and global_delta: none, and moves the default plan to needs_replan. Never describe a rejected candidate as a completed research result.

For accepted work, record two separate deltas:

• campaign_delta: none | incremental | substantial | closed
• global_delta: none | reduced | satisfied

Global progress requires evidence-backed reduction of a named bridge or terminal obligation. Work under scope_lock: encoding_only remains campaign-local unless it discharges such an obligation. Special cases, elegant reductions, finite samples, and uncertified counterexamples are progress to record, not success stops.

The obligation DAG is enforced: transitions cannot skip open dependencies, and all success-criterion obligations must be satisfied/closed before the host declares the goal satisfied. Criterion ids are unique, and a pre-completed node counts only when it has evidence and completed dependency closure. The host, not the worker's requested decision, derives successful termination from that reviewed post-state. Reported compute services must satisfy current_plan.compute_policy; with an active restriction, unreported provenance cannot be banked. A host-derived early success remains subject to the loop's machine-checkable proof-artifact gate.

Migration and legacy compatibility

Use the runtime's goal-focus migrate --dry-run before --apply. The dry run compares dynamic campaign signals from the current path, recovery, latest finalized ledger, and hard-replan audit. If those signals disagree, migration must report ambiguity and refuse to guess. Apply may preserve the disagreement as an unselected needs_replan plan, but enforce mode cannot dispatch until structured strategy review or an explicit reviewed active-campaign choice resolves the direction.

Apply creates a timestamped .goal_focus_backups/ copy of the legacy control files before transactionally creating v2 state, then reconciles and validates the compatibility views. Apply refuses when the loop registry identifies a live owning driver. Its proposal, backup postimages, and commit share one exact snapshot of every legacy input (including the hard-replan audit); hash/absence compare-and-swap rejects concurrent mutation with no partial v2 state. Pause a live loop at an iteration boundary before migration.

Unmigrated goal_priority.v1 remains supported through {loop_dir}/goal_priority.json or loop_state.standing_orders.goal_priority. Its executable defaults are enabled: false and discipline_mode: soft. When explicitly enabled, it adds goal-EV advice, campaign prompt text, and warnings, but does not provide v2's dispatch or review-before-bank guarantees. Opt out with "enabled": false or AAS_AUTOLOOP_GOAL_PRIORITY=off; env on forces enable only when a v1 config object exists.

The v1 contract remains available as canonical/templates/goal-priority.md and canonical/templates/goal-priority.example.json. The v2 contract is canonical/templates/goal-focus.md. Use decision-doubt-loop for a load-bearing close, reopen, or switch decision outside the host strategy-review path.

Multi-Agent Use

Recommended hybrid (parent-owned panel + single-path worker)

For unattended loops that need multi-agent advice/review, prefer the host parent model owned by autonomous-research-loop-runtime:

1. Goal Focus strategy review — when v2 requires a plan, top-level provider CLIs return structured strategy_advice.v1; legacy loops continue to use target_advice.
2. Drive primary — exactly one provider runs the reviewed bounded action; it must not nest panel CLIs under its sandbox.
3. Stage — successful primary output becomes a pending candidate, not a banked ledger row.
4. Different-family result review — a host-owned reviewer returns strict result_review.v1 for that candidate.
5. Atomic host finalize — accept or reject through the transaction layer, then notify from finalized state.

Enable with drive --panel on|auto|off, panel.json, loop_state.standing_orders.panel, or AAS_AUTOLOOP_PANEL=on. Run … panel --smoke to probe providers. When goal_priority is active, target advice should rank by goal EV (see above). Panel provider budgets use adaptive timeouts by default (prompt size, provider multipliers, recent elapsed history, hard max); set "timeout_mode": "fixed" in panel.json for legacy flat caps.

Provider credit / usage limits

Agent CLI credit exhaustion (Codex/Claude/Kimi usage limits, rate limits) is operational, not a research stop. Follow instruction provider-credit-quota.md:

• Set exclude_until_credit (or shrink providers) in panel.json / standing_orders.panel so exhausted providers are not re-invited.
• If the drive primary is exhausted, restart drive --provider <funded> rather than leaving quota_wait spinning when a fallback primary exists.
• Cross-agent packets: parent re-targets the recipient; do not embed billing recovery (see cross-agent-delegation).

Do not treat nested “primary agent shells out to four CLIs” as the architecture (that failed under Codex workspace-write sandboxes). For heavy strategy pauses, use agent-group-discuss instead of per-iteration AGD.

When using subagents outside that driver path:

1. Create bounded task packets with objective, evidence required, exclusions, and expected output.
2. Limit child workers to the budget in budget.json.
3. Require each child result to report inspected and uninspected evidence.
4. Synthesize child outputs before making decisions.
5. Do not let child agents recursively start unbounded cross-provider trees.

For panel-style discussion outside ARL drive, pair this skill with agent-group-discuss or prose when available.

Recovery

After every material iteration, update recovery.md with:

• current goal
• last completed iteration
• current status
• next safe action
• remaining evidence gaps
• active blockers
• budget remaining

On resume, read loop_state.json, budget.json, iterations.jsonl, and recovery.md before acting. Validate state before continuing.

Truly Autonomous Execution

A chat session cannot carry a long loop by itself: context windows and turn boundaries end it. For unattended multi-day runs, prefer the force-loop kit (default pins: Goal Focus enforce, goal_priority hard, notify auto/on; Linux/macOS/Windows/WSL):

... force-loop/run_force_loop.sh bootstrap --loop <loop_dir> --root <project> --profile formal --goal "…"
... force-loop/run_force_loop.sh start --loop <loop_dir> --root <project> --provider <claude|codex|…>

Raw headless drive remains available; it respawns a fresh agent session per iteration against on-disk loop files and owns stop conditions:

... run_autonomous_research_loop.sh drive --dir <loop_dir> --provider <claude|codex|deepseek|opencode|copilot|antigravity|grok|kimi>
# notify defaults to --notify auto (remote-bridge when secrets configured)
# enforce-mode external delivery also requires AAS_AUTOLOOP_EXTERNAL_NOTIFY_EGRESS=allow
# silence with --notify off or AAS_AUTOLOOP_NOTIFY=off

agent-cmd --provider all --dir <loop_dir> prints the per-target iteration commands and probes binary availability. The driver captures per-iteration logs, re-checks the stop conditions every cycle, and treats detected credit/quota outages as pause-and-wait (not failure), resuming when credits return. Progress notify uses the remote-bridge skill by default when Zulip/Telegram secrets exist (--notify auto on arm/drive/watch); failures to send never stop the loop. Interactive sessions on Claude are additionally governed by the installed hooks.Stop entry while a loop is armed (arm --dir <loop_dir> --root <project_root>): the hook blocks turn-end until a real stop condition fires. Kill switches in both modes: touch <loop_dir>/STOP_REQUESTED, touch <loop_dir>/PAUSE, AUTOLOOP_DISABLE=1, or disarm.

For an enforce-mode loop, finding configured credentials does not itself grant network egress. AAS_AUTOLOOP_EXTERNAL_NOTIFY_EGRESS=allow is required before the host sends a notification; without it the runtime records only the local notification audit/result. External strategy/result panels likewise require AAS_AUTOLOOP_EXTERNAL_PANEL_EGRESS=allow. Enabling panel egress authorizes the complete bounded authority brief and staged evidence snapshot to leave the host for each selected reviewer.

Notify v2 operator contract

Progress notifications are operational summaries, not evidence and not a substitute for result review. New structured events use aas.autoloop.notify.v2 and must make the research state understandable without opening the ledger:

• Goal — what main problem the loop is solving.
• Completed — what was actually finalized, or an explicit statement that nothing was banked.
• Current — where the research stands now and the event's plain-language outcome.
• Plan — the next bounded action or why the loop is waiting.

Every rendering also carries a research-specific title/topic, iteration/review/ loop status, iteration-budget and goal-progress summary, executor, structured driver/panel/other-agent provenance, structured compute provenance, and finish time/duration for terminal iteration events. Panel provenance lists agents that actually returned usable work, not the configured invite list. For every agent group, an explicit empty list means none was used; reported: false means legacy/unreported. Compute is explicit: an empty reported run list means none was used; reported: false means legacy/unreported. Do not infer Hetzner, Kaggle, Modal, GitHub Actions, local, or another service from prose or paths.

Before delivery, dry-run output, transport results, fingerprinting, or dedupe persistence, configured transport secrets and common credential forms are redacted recursively from every string value in the event envelope, including extension fields and event ids. A redacted event id is replaced by a stable opaque digest-derived id. Redaction retains provider/model/family/role and compute service/status provenance when those values are non-sensitive. Common explicit PII forms (email, phone, government id, address/DOB, and labeled participant/patient/subject data) are likewise redacted. This is a last-mile guard, not a complete personal-data classifier.

The runtime keeps flat compatibility fields while structured consumers migrate. Markdown, plain, bounded Telegram HTML, and compact renderings all retain the mandatory fields. Notification delivery is best-effort and never changes loop truth. Timestamp-rebuilt but materially equivalent retries share a short-lived semantic identity and a cross-process check-send-remember lock; materially changed status, content, agent, or compute fields do not. The runtime records delivery state only after the selected transport reports success. Remote endpoints require HTTPS, reject URL credentials and redirects, and permit localhost HTTP only with its separate explicit development opt-in. External panel prompts are not silently rewritten because that could change evidence meaning: detected PII instead blocks the call unless the operator has approved the SHA-256 of those exact outbound bytes via AAS_AUTOLOOP_EXTERNAL_PII_APPROVAL_SHA256.

Stop Rules

These rules are governed by the enforcement policy in canonical/instructions/autonomous-loop-enforcement.md. User requirements override everything; the conditions below are the defaults used only when the user set no overriding requirement.

Stop immediately and report status when:

• success criteria are satisfied, confirmed by a machine-checkable success check
• any hard budget is exhausted, including credit, a spend cap, wall clock, or the iteration count
• the user asks to pause, stop, or switch tasks

A repeated blocker, an unresolved evidence gap, or a next action that would exceed the approved scope is not, by itself, a stop under these defaults. Record it, choose an in-scope action, and continue, downgrading the iteration decision to revise or delegate. Such a signal ends the loop only when no in-scope action remains and it also satisfies one of the conditions above, or when the user set it as an explicit stop condition.

When stopping, report:

• status: complete, stopped, or blocked
• iterations completed
• evidence inspected
• remaining unchecked items
• next recommended action

Output Contract

For user-visible summaries, use this compact shape:

Scope: ...
Status: ...
Evidence Checked: ...
Iterations: ...
Decision: ...
Remaining Gaps: ...
Style: ...
Next Action: ...

If material evidence remains unchecked, explicitly say incomplete analysis before the provisional recommendation. For finalizable prose artifacts created during the loop, record style_profile_ref, active_overlays, active_requirement_ids, and style_applied in the loop ledger or artifact-adjacent style record. Do not count a bare style_applied: true value as force-use evidence.

Recommended templates

When this skill is involved, consider these workflow templates (install via the workflow-templates artifact profile, or --with-deps to pull backing skills):

• autonomous-research-loop-runbook -- Bounded autonomous research-loop runbook with four stop conditions, single-path solving, mandatory cross-agent verification, fresh-agent backtracking, and five-lane broker-routed heavy-compute offload with per-lane safety gates.
• autonomous-research-loop-portfolio-runbook -- Open-problem, portfolio-first variant of the autonomous research-loop runbook: a rigorous definition-of-done with an insufficient-result disqualification list, an approach registry with blocked-route discipline, and an adversarial audit gate with a concrete-deliverable requirement, keeping the same four stop conditions, cross-agent verification, fresh-agent backtracking, and five-lane broker-routed heavy-compute offload with per-lane safety gates.
• arl-scripted-force-loop -- discovery for the default scripted force-loop kit (runtime force-loop/).
• goal-focus -- Goal Focus v2 authoritative-state, selection, review-before-bank, migration, and notification contract.
• goal-priority -- legacy goal_priority.v1 reference (defaults disabled/soft; does not change stop conditions).
• informal-to-lean-formalization-runbook -- F1–F7 formalization positions when path is formal-track under formal_policy.
• sample-arl-headless-driver-with-formal -- thin formal-env layer only (not the force-loop default).

When formal_policy is auto, on, or force, wire lean-research-library at F2' (search-first) and F7' (user-gated intake); staging and outward-facing actions batch at run boundaries and always wait for the user.
