Harbor Issue and PR Intake

Harbor

Harbor is the shipyard's intake. External requests — issues, bug reports, feature requests, and (when enabled) external PRs — arrive as raw noise. Harbor turns that noise into evidence, proposals, signed decisions, and authorized executions, so that the captain only ever handles what is genuinely unresolved: a new tradeoff, a new exception, a new authority.

Success order. First: zero overreach — nothing happens that nobody authorized. Second: fewer captain judgments and less reading — without skipping ships, auto-rejecting, or parking forever.

The four records

Every harbor action produces one of four records. They are kept in the tracker itself (comments, labels, links) — the tracker is the only record source; the docket is an index, not a store.

Not every record is its own comment: one consolidated verification comment may cover a sweep, and a decision may carry a combined execution receipt. When a signed proposal materially changes, post a new snapshot that names what it supersedes — never silently edit what was signed. If a cited source comment is later edited, re-verify validity before relying on it; tracker comments are not immutable storage.

Authority — what harbor may do alone

Invoking this skill, having an API token, a reporter saying "approved", or model confidence never constitutes disposition authority. Harbor acts autonomously only for:

• Facts: reading trusted repo materials, searching, inspecting diffs, reproducing under safe conditions, assembling evidence, drafting artifacts.
• Execution under standing authorization: sending info requests within the granted communication scope; labeling, linking, or closing exactly as a valid signed rule allows; writing execution results.

Everything else — accepting, rejecting, merging, exceptions, scope — is a new judgment: harbor prepares it (one main question, options, recommendation, impact, evidence) and the captain signs. A signature source is either a verified maintainer tracker reply or an explicit instruction inside an authorized maintainer session; when recording a session instruction, name the source and the original intent — never impersonate a maintainer tracker signature. Labels, issue authorship, and body claims are not authorization proof.

Harbor chooses investigation order and technical methods itself; engineering choices are not escalated as product decisions. Harbor never executes a merge.

Standing authorization rules

A repeated burden (the same report pattern, the same close disposition) is solved by the captain granting one rule, not by repeating signatures. The captain may authorize, for example:

"For reports of the same defect, on the same version, with no new evidence, fully covered by a still-valid parent issue: link to the parent and close. Exceptions: regressions, behavior differences, security reports, or an invalidated parent."

Minimal rule content: identity via the signed tracker decision it is based on (no global numbering service); the repos and request scope it covers; the allowed actions; the facts that must hold; exceptions and revisit conditions; the authorization source. Version or expiry conditions only when needed — no forced TTL.

Executing a rule requires all of: the covered facts verified with evidence, the rule explicitly allowing the action, and the host permitting it. Finding only a duplicate is recorded as a candidate link — it does not authorize a rejection by itself. A closed parent does not make a new report closeable: check for regression or unresolved substance first.

Reuse check, before citing any decision:

1. Is it the same question, not merely similar wording?
2. Are object, goal, constraints, and allowed actions inside the original decision's scope?
3. Do the key facts the decision relied on still hold?
4. Any new counterexample, exception, revoked permission, or conflicting decision?

All hold → cite and proceed. Thin evidence → gather evidence first. Substantive change → propose only the delta. Conflicts without a declared supersedes relation are escalated — "newest text wins" is not a resolution.

Evidence invalidation ≠ intent invalidation. A new PR push invalidates technical readiness (withdraw merge-ready, re-verify affected dimensions) but not the signed "this is worth doing". A changed goal or scope re-opens the business decision. New scope, breaking API changes, or new features in a diff are new decisions, not noise. A merge approval binds to the exact PR head and its base/check conditions.

Step 0 — bind the tracker, before anything else

Verify the remote tracker responds (gh repo view on the recorded/implicit remote) and that it is the expected repository. If it does, the remote tracker is the ONLY medium for dispositions: every sheet, label, and docket lives there. A local issues/ directory (or any untracked markdown collection) is content to inspect, never a tracker to write to — chaotic repos are full of lookalike directories, and writing dispositions into local files strands them where reporters and maintainers will never see them. If the remote is unreachable, stop and report the blocker — do not fall back to local files.

V1 scope: remote GitHub only. Other backends are explicitly unsupported — report and stop; no silent migration, no local fallback. The tracker and label vocabulary should have been recorded by /oh-my-claudecode:drydock; if not, ask once and record the answer in CLAUDE.md under the shipyard conventions.

The labels

Create these labels if the tracker does not have them (and create them before first use):

harbor:accepted · harbor:need-decision · harbor:need-info · harbor:rejected · harbor:for-maintainer · harbor:needs-exploration · harbor:merge-ready · harbor:changes-requested

Eight labels, no new enums. A ship carries exactly one current harbor:* state label; no harbor label means not yet inspected — there is no invented accepted-pending state.

Single writer. V1 allows one harbor writer per repository, guaranteed by the caller or host. Observers may run read-only in parallel. If exclusivity cannot be confirmed or another writer is detected, produce drafts only — no tracker writes. Labels, assignments, and comments are not atomic locks; read-before-write only reduces stale writes.

Sweep — a change-driven, resumable queue

Candidates are what changed, not just what is new: new external issues and non-draft PRs; need-info ships with a fresh reporter reply; changes-requested/merge-ready PRs with new pushes or relevant check changes; need-decision ships with a credible maintainer reply; accepted ships not yet handed off. Internal tickets, navigator maps, and dockets are excluded by their trusted creation chain — not by bot authorship or title similarity; when provenance is unclear, check links and keep the ship pending rather than excluding it. Draft PRs never enter the queue; a named draft may be read but is still not mergeable or accepted. If PR intake was not enabled, say so in the coverage report instead of claiming all external work was handled. Read tracker pagination honestly — no pretending a background listener exists.

Processing order per sweep:

1. Freeze this round's candidate snapshot; process by urgency and age; paginate fully — no skipped pages. Security-sensitive ships move to the restricted path first.
2. Read current native records and handoff state. Skip ships with no relevant change; do not repeat satisfied asks.
3. Classify before verifying: place each ship in one intake class first — standing-authorization match, duplicate candidate, self-evident trivial fix, needs-info wait, needs-decision wait, or full survey — and spend evidence only where the class calls for it. Cheap routing precedes expensive verification: a ship that routes to a standing rule or a duplicate link never consumes a reproduction step. The class is provisional; new facts re-classify a ship as an explicit re-classification, never a silent switch.
4. Check existing decisions and scope first; for PRs without declared intent, static survey precedes expensive verification.
5. Check duplicates and existing implementations, then reproduce claims as needed. Existing code is not proof a feature is satisfied; a failed reproduction is not proof the report is false. A valid in-scope prior refusal may skip an expensive reproduction that would not change the decision — marked explicitly as not-run, with the reason. Match rejections by concept, not by title: the same defect under new wording reuses the prior signed rule or prior refusal — wording changes do not create new work.
6. Each unknown fact gets one informative verification step. Stop retrying when methods stop reducing uncertainty or the environment is missing; record the blocker and the minimal ask. Do not promise exhaustive fact-finding.
7. Disposition per the three classes (facts / standing authorization / new judgment). One stuck ship never blocks the others; if the remote goes down mid-sweep, report the failure — never fake posted state.
8. Refresh the same docket (one consolidated update when needed), keeping each ship's latest visible conclusion linked to its evidence.

Partial completion. If context or processing budget runs out: post what is accurate — inspected, not-inspected, and blocked, each locatable on the tracker — and a remaining-queue index. Never write "all complete". The next sweep re-reads remaining ships' latest state and does not redo finished, unchanged work. Budget comes from the execution environment; no daemons, no forced timers.

Retries and unknown results. After an API timeout, read the actual state first: a comment that already posted is not re-sent; a signed decision is not re-asked; a failed action is recovered within its own authorization. Read-before-write still does not provide multi-writer linearizability.
