The +shared `/label-issue` helper from [#5355](https://github.com/NVIDIA/OpenShell/pull/5355) +owns eligibility, evidence, validation, label writes, checkpoints, and local +reporting. No automatic workflow is installed. + +## Execution boundary + +Select an invocation with `labeling_agent_events.select_invocation`, then call the +shared helper's preparation. Only `status: ready` with `classifier_required: true` +creates a model session. Pass the prepared evidence and trusted classifier +instructions to `managed_label_classifier.session_request`, call `classify`, and +return its proposal to the shared preview/application helper. Follow the shared +[command/result contract](https://github.com/NVIDIA/OpenShell/blob/70fa003b902416459b2c08131b5cc265294d35d6/.agents/skills/label-issue/references/result-contract.md); +this adapter checks JSON shape, not classification validity. + +Include the result schema and referenced classification guidance in the trusted +instructions: the runtime cannot fetch referenced files or expand evidence. +The caller must handle required evidence expansion through the shared helper. +Do not silently treat missing or partial evidence as complete. + +Trusted instructions become the session system prompt; evidence becomes the user +message. Session overrides disable tools, MCP servers, and attached skills without +changing the saved agent. The adapter supplies no GitHub credentials, repository +mounts, or vaults. + +Use a dedicated single-agent CMA configuration and an environment without +preinstalled secrets. Start with a Sonnet-level model; the adapter pins the agent +version rather than choosing a model. Verify overrides in a live smoke test before +enabling automation. + +## Smoke-test CLI + +This temporary harness previews or submits prepared inputs. Consolidate it into +the real entry point when the shared-helper integration is available. + +```shell +uv run --no-project python tasks/scripts/managed_label_classifier.py \ + --instructions /path/to/trusted-classifier-instructions.md \ + --evidence /path/to/prepared-evidence.json \ + --agent-id agent_CONFIGURED_ID --agent-version 1 \ + --environment-id env_CONFIGURED_ID +``` + +By default it prints the request without API calls or credentials. Output includes +item evidence; keep it in the invoking session or appropriate artifacts. + +Add `--run` with `ANTHROPIC_API_KEY` in the environment to create a billable +session. Never include credentials in evidence. Defaults are a 25-US-cent +list-price ceiling (`--budget-cents`) and a 180-second deadline (`--timeout`). +The result contains `session_id` and `proposal`; validate the proposal through +the shared helper. Ambiguity belongs in local reports, never item comments. + +## Completion and recovery + +Success requires JSON `agent.message` followed by idle `end_turn`. Failure or +timeout archives the session; archival failure reports its ID. Successful +sessions remain available for review. Session creation is never retried +automatically after an uncertain response. Polling is bounded and error bodies +are suppressed. See the [session event API](https://platform.claude.com/docs/en/managed-agents/events-and-streaming). + +## Invocation selection + +`select_invocation` returns `Invocation(repository, number, force, source)` or no +invocation: + +- `issues` / `pull_request_target`: `labeled` with `state:accepted`, including + automation-applied labels and drafts. +- `issue_comment`: a new human PR comment containing only `/label-issue`, + `/label-issue force`, or `/label-issue --force`. +- `workflow_dispatch`: a same-repository issue/PR number or URL and a Boolean + force input. + +Human commands require current write, maintain, or admin permission. Supply a live +permission lookup that propagates failures; author association is insufficient. +Force bypasses only unchanged detection in the shared helper. Other label and +lifecycle events do not dispatch the classifier. + +## Pending wiring + +After observed skill runs succeed, connect these modules using #5276's integration +plan and trusted default-branch code. All entry points need coordinated per-item +execution; #5355's local lock does not serialize separate hosts. + +[#5260](https://github.com/NVIDIA/OpenShell/pull/5260) writes acceptance using +`GITHUB_TOKEN`; its label event will not start another workflow. Invoke the shared +entry point explicitly after a successful acceptance-label write, including for +drafts, independently of later reviewer-routing success. An existing acceptance +label alone is not current eligibility: #5260 does not refresh it. Use the shared +helper's preflight, which checks the item's author rather than the triggering +actor and propagates lookup failures. + +Remaining prerequisites are the shared interfaces, reviewed CMA configuration, +acceptance-writer hook, label preparation, and observed end-to-end runs. See #5355 +for canonical-label and `meta:labeler-checkpoint` prerequisites. + +## Verification + +```shell +mise run test:labeling-agent +``` + +Offline tests fake CMA and permissions and perform no remote writes.

Rebase onto the PR for +[#5411](https://github.com/NVIDIA/OpenShell/issues/5411), reconcile the runner +interface, and complete the integration steps below before enabling previews. + +## Design and boundaries + +`labeling-dispatch.yml` selects explicit acceptance labels (including draft PRs), +new authorized human PR commands, and authorized manual workflow dispatches. +Creation/reopening, unrelated labels, and checkpoint bookkeeping do not select +classification. Current permission lookup errors fail the run. The acceptance +writer may dispatch as `github-actions[bot]`; this identity cannot use force. +All selected runs still pass through the shared runner's current eligibility gate. + +The proposed #5411 adapter is `labeling_runner.run(repository, number, *, force, +apply) -> report`. Confirm this against the actual runner during rebase. The +runner owns prepare, evidence expansion, deterministic unchanged/ineligible skips, +classification, validation, preview, application, and recovery. This layer must +never duplicate those operations or treat a historical acceptance event as current +authority. Force bypasses only unchanged detection. + +A workflow concurrency group alone cannot coordinate direct helper calls on +another host. `labeling_item_lock.item_lock` instead arbitrates ownership through +atomic GitHub ref creation at `refs/labeler-locks/NUMBER`. Each acquisition creates +a unique audit commit based on trusted repository code. All mutation paths must +use this same guard; until they do, cross-entry-point serialization is incomplete. +This is not a new classification checkpoint or a lease. Checkpoints and partial +write reconciliation remain in the shared helper. No external datastore is used. +See the [GitHub refs API](https://docs.github.com/en/rest/git/refs). + +Successful execution verifies ownership and removes the ref. Failure, lost +responses, cancellation, or crashes leave it in place. There is no time-based +steal or blind retry. A busy run fails visibly rather than silently dropping a +request. It creates no model session or item writes. Inspect the lock commit and +owner execution, stop that execution, inspect current labels/events and the +runner's partial-write report, and explicitly reconcile before removing the lock. +Only then rerun with fresh preparation. Never delete a lock while its owner may +still execute. Do not enable automatic retry of an uncertain operation. + +Successful PR application always calls the existing reviewer reconciler under +the same guard. An unchanged result also calls it, allowing a prior handoff to +be recovered without another classification. The reconciler preserves draft, +closed PR, author, engagement, and manual reviewer protections. A failure retains +the lock and requires the recovery above. Preview and ineligible skips do not +mutate reviewer requests. Routine outcomes never post item comments. + +## Required integration on rebase + +- Replace the provisional adapter with #5411's real interface and report statuses. + Preserve the runner's actionable recovery report on errors. +- Guard direct shared-helper classification and assessment application, runner, + human and triager calls with this same mutex. Avoid nested acquisitions: one + lock must cover preparation through final writes and reviewer handoff. Callers + must not have an uncoordinated mutation escape hatch. Update `/label-issue` and + triager instructions against the actual combined helper. +- In #5260's acceptance writer, call + `acceptance_written(repository, number, default_branch, api=api)` immediately + after a successful acceptance-label POST and before any reviewer operations or + draft return. Grant its workflow `actions: write`. Explicit workflow dispatch + works with `GITHUB_TOKEN`; its label event does not start a downstream workflow. + A dispatch failure must surface independently of later routing. When retrying + a previously successful write, explicitly enqueue again; the fresh runner + checkpoint determines whether work is needed. Add integration tests at the + actual writer covering drafts, routing failure and dispatch failure. +- Obtain the human policy for materializing implicit issue acceptance; use the + shared accepted-work policy and deterministic authority checks. No model may + decide acceptance. This branch intentionally implements no policy before that + decision. Add its reviewed materialization path and tests here after approval. +- Register the mutex in the real helper and test separate processes/hosts, + duplicate delivery, current eligibility loss, uncertain writes and reviewer + recovery using the actual runner and helper interfaces. The injected tests in + this branch do not substitute for those integration tests. + +## Preview and application rollout + +Keep `LABELING_PREVIEW_ENABLED` and `LABELING_APPLICATION_ENABLED` unset initially. +The workflow installs without running. Merging the dormant workflow does not +satisfy the issue's observed end-to-end acceptance criteria. + +After dependency wiring and reviewed policy, provision the dedicated CMA +configuration and scoped credentials described in +[the runtime guide](README-labeling-agent.md). Finalize environment variable names +against #5411; never derive configuration or code paths from item text. Give the +configured labeling identity authority for the shared helper and access to the +repository's refs, issues and PRs. Provision canonical labels, routing support, +and the approved checkpoint label from #5151/#5355. Verify custom ref creation, +content permissions, and recovery in a disposable repository first; no live ref +writes have been performed by this branch's offline tests. + +Create separate `labeling-preview` and `labeling-application` GitHub environments. +Store `LABELING_ANTHROPIC_API_KEY` in the appropriate environment. Protect the +application environment with required human reviewers and default-branch +restrictions. Enable `LABELING_PREVIEW_ENABLED=true` first, leaving application +unset. Observe human and automation-applied acceptance, drafts, human command and +force, triager, duplicate, missing evidence, and partial-failure paths. Record +run URLs and the reviewed results in the PR before requesting application. + +Only after observed previews and explicit human approval, enable +`LABELING_APPLICATION_ENABLED=true`. This switches selected invocations to the +protected application environment. Inspect one-item writes and reviewer handoff +before broad operation.
