GitHub Issue Sync

Sync current plan progress to a GitHub Issue: $ARGUMENTS

If no argument is provided, search for an issue ref (org/repo#<number> or https://github.com/<org>/<repo>/issues/<n> URL) in the active plan file (most recently modified .md in plans/).

Optional arguments include pr_url=<url> for the live pull request and merge_sha=<sha> once merged.

Workflow

Step 1: Identify Issue and Context

1. Parse issue ref from $ARGUMENTS or extract from the active plan file.

2. Fetch current issue state:

   gh issue view <number> --repo <org>/<repo> --json number,title,state,labels,milestone,assignees,comments,url
   

3. Determine current milestone by checking:

   • Does a plan file exist? → Plan created
   • Is there a working branch? → Implementation started
   • Are tasks in progress? → Active implementation
   • Is there an open PR? → PR ready for review
   • Is the PR merged? → Complete

Step 2: Gather Update Content

Milestone	Content to post
Plan created	Plan summary, branch name, link to PR (if draft exists)
Implementation in progress	Task completion summary (X of Y tasks done), any blockers
PR ready	PR link, summary of changes, test results
PR merged	Final summary, suggest moving issue to status:done

Step 3: Post Update

1. Idempotency check — read the issue's recent comments. If the most recent comment with the prefix [claude-sync] <milestone> matches the current milestone AND the body content is unchanged, skip the post (no duplicate).

2. Add the comment:

   gh issue comment <number> --repo <org>/<repo> --body-file /tmp/sync-comment.md
   

   The body must start with [claude-sync] <milestone> so the next sync run can dedupe.

3. Report to the user what was synced.

Step 3b: Ensure PR Backlink

When $ARGUMENTS includes pr_url=<url> for PR ready or PR merged, ensure the GitHub Issue has a durable ticket -> PR link:

1. Make sure the PR body contains Refs #<n> (or the fully qualified cross-repo form) — never a closing keyword, per the GitHub rule in lisa-git-submit-pr. Read the issue side with gh api graphql against issue.timelineItems, or gh issue view <number> --json closedByPullRequestsReferences. Not gh issue view --json timelineItems: timelineItems is not a supported field for that command, so the check silently returns nothing useful rather than failing loudly.

2. Establish the managed backlink comment by running the command that owns it — never by hand, and never by describing the procedure here:

   node scripts/lisa-work-item.mjs backlink --ref <work-item> --pr-url <url>
   

   It creates the [lisa-pr-link] comment or updates the one already present, instead of appending duplicates, so it is safe to run on every milestone. This is unconditional, not contingent on step 1 failing: under the non-closing rule GitHub never creates a native development link (that surface is the closing-reference mechanism), so this comment is the only ticket-side backlink there will be — run it whether or not native linkage exists or cannot be verified, because the required Work-Item Traceability check reads this comment and nothing else guarantees one. The comment carries the marker and the PR URL only; the milestone (pr-ready / pr-merged) and merge SHA belong in the milestone progress note, so that a rerun at a new milestone still converges on one backlink comment.

Native GitHub linkage cannot be verified under the non-closing rule because it is never created in the first place, so the managed comment is not a contingency here — it is the mechanism. The issue must show the PR from at least one ticket-side surface, and this is the only one available.

Step 4: Suggest Status Transition

Based on the milestone, suggest (but do NOT automatically perform) a label transition:

Milestone	Suggested label
Plan created	status:in-progress
PR ready	configured done label (status:done in this repo)
PR merged	no additional build-label transition

The actual status:in-progress flip is owned by lisa-github-build-intake (claim) and lisa-github-agent. The configured done flip is owned by the build-intake owner after a successful build and evidence post. This skill never relabels.

Every suggested transition is bound by the Tracker status vocabulary section of lisa-tracker-sync — cite it, do not restate the policy. GitHub has no review lane (BUILD_LABEL_DEFAULTS seeds no review key, and config-resolution records "no default review label"), so the pr-ready milestone suggests the configured done label directly; there is no intermediate hop to skip. Resolve every label through the shared resolver rather than an inlined helper.

Step 5: Parent Status Rollup (--rollup)

When invoked with --rollup, this skill derives a parent/container issue's status:* label from the roll-up of its child sub-issues instead of posting a milestone update on a leaf. This implements the GitHub sub-issue-completion arm of the Parent status rollup (the state machine) section of the leaf-only-lifecycle rule — cite that rule, do not restate the policy. It is the sync-side complement to the write-time labeling (lisa-github-write-issue), the validate-time S15 gate (lisa-github-validate-issue), and the claim-time gate (lisa-github-build-intake); all four cite the same rule so the classification never drifts.

Resolve the child set the same way lisa-github-read-issue does — native sub-issues via GraphQL, each with its status:* label and open/closed state:

gh api graphql -f query='
  query($owner:String!,$repo:String!,$number:Int!){
    repository(owner:$owner,name:$repo){
      issue(number:$number){
        number title state
        subIssues(first:100){ nodes { number state labels(first:20){ nodes { name } } } }
      }
    }
  }' -F owner=<org> -F repo=<repo> -F number=<parent-number>

If the subIssues field is unavailable (older GHES), fall back to body parentage exactly as lisa-github-read-issue does. If the issue has no children it is a leaf, not a parent — rollup is N/A; behave as a normal milestone sync.

Evaluate the required children over the env ladder in-progress < dev < staging < production (the ordered keys of the GitHub env-keyed done map, e.g. status:on-dev < status:on-stg < status:done) and take the first match (canonical roles from config-resolution; the GitHub label map is status:blocked, status:in-progress, env-keyed done):

If among the required child leaves…	Derived parent role	GitHub label
any child carries status:blocked (or is otherwise blocked)	blocked	status:blocked
else every required child has shipped to some env (each at a done-map label, e.g. status:on-dev/status:on-stg/status:done)	done[min-env]	the least-advanced env label among them (all status:on-stg → status:on-stg; mixed dev+staging → status:on-dev; all production → status:done)
else any child has started (status:in-progress, or shipped to an env while a sibling has not)	claimed	status:in-progress
else (children exist, none started)	—	unchanged — parent keeps its non-ready container label

• Blocked dominates — and the rollup must say which child and which kind — a single blocked child surfaces status:blocked on the parent even while siblings progress, so a human sees the parent needs attention. status:blocked alone is a single bit and cannot tell a child waiting on an external event from one whose acceptance criteria are unbuildable; the second never clears on its own.
• Run the shared classifier for every derived rollup state before writing the label or comment, not only for status:blocked. Include the exact rendered state and child tally in the classifier input alongside the resolved child graph, so its fingerprint and change.summary deduplicate the complete rollup note for status:in-progress, every env-keyed done, and status:blocked alike:

run_rollup_classifier() {
  local input_path="$1"
  local attempted_paths=""
  local seen_root=""
  local candidate_suffix="scripts/rollup-blocker-classification.mjs"
  local root root_real candidate candidate_real expected_candidate
  local classifier_output

  for root in "${CLAUDE_PLUGIN_ROOT:-}" "${PLUGIN_ROOT:-}"; do
    [ -n "$root" ] || continue
    [ "$root" != "$seen_root" ] || continue
    seen_root="$root"
    case "$root" in
      /*) ;;
      *) continue ;;
    esac
    case "$root" in
      */../*|*/..|*/./*|*/.) continue ;;
    esac

    candidate="${root%/}/$candidate_suffix"
    if [ -z "$attempted_paths" ]; then
      attempted_paths="$candidate"
    else
      attempted_paths=
    

    root_real= || 
    [ -f  ] && [ -r  ] || 
    candidate_real= || 
    expected_candidate=
    [  =  ] || 

     classifier_output=; 
        
       0
    

      \
       >&2
     1
  

    \
     >&2
   1
}

 ! CLASSIFIER_REPORT=; 
    >&2
   1

When the derived state is blocked, its report names, per class, the blocking leaf, the path to it (#1495 -> #1515 -> #1547) and who must act — that text goes in the rollup comment verbatim. It exits non-zero when it classified nothing (unreadable graph, no children, no readable child): that is a strict no-write result. Do not change a label and do not post/update a rollup comment; report the classifier failure to the caller. Never fall through to "no blocked children", infer a class from prose, or apply the spec_defect marker from a flow — see leaf-only-lifecycle → Classifying a hold.

• Least-advanced env wins — the parent reaches an env only when every required child has reached at least that env; it never sits ahead of its laggard child. Native closure (gh issue close --reason completed) fires only when the resolved env is the production status:done, never at status:on-dev/status:on-stg.
• "Required" children only — a child labelled won't-do / optional does not hold the parent open; only leaves that must ship count toward the env-rollup check.
• Recursive — a parent reaches an env only when its children have all reached at least that env; an Epic reaches it only when its Stories have themselves rolled up to it. Evaluate bottom-up.
• Never set the parent to status:ready — ready is leaf-only (the human "claim this" signal). Rollup only moves the parent between non-ready container labels.

Single-environment collapse (this repo). .lisa.config.json deploy.branches declares only production: main, so the env-keyed done resolves to the single label status:done — there is no status:on-dev / status:on-stg and no dev → staging → prod promotion chain. Resolve the env rungs via the env-keyed done logic in config-resolution, but in the single-environment case the only rung is production and it collapses to the one status:done value; the rollup never attempts to resolve a dev or staging done. Projects that DO have multiple environments keep the env-keyed map and roll the parent up to whichever done (including intermediate status:on-dev/status:on-stg) its leaves have collectively reached.

Apply the derived label (only when it differs from the parent's current status:*): remove the parent's existing status:* label and add the derived one, keeping exactly one status:* label so the build-queue invariant holds. Re-read the labels immediately after the edit and require exactly one status:*; if the count differs, surface an error and stop without trying to normalize the ambiguous set automatically. Post an idempotent [claude-sync] rollup comment naming the derived state and the child tally (e.g. 3/4 leaves terminal, 1 blocked → status:blocked); when the derived state is status:blocked the comment also carries the classifier's per-class section, so the blocking child and its actor are one read rather than a descent. Persist the classifier's change.fingerprint with the rollup comment and use change.changed as the dedupe decision for every rollup. Use change.summary only as display text; it describes the transition and is not a stable key.

gh issue edit <parent-number> --repo <org>/<repo> \
  --remove-label "<current status:*>" --add-label "<derived status:*>"

Safe default. If a successfully-read rollup cannot be applied automatically (e.g. ambiguous required-set or a derived terminal that the env logic cannot resolve), this skill does not guess — it posts the derived suggestion as a comment and leaves the parent's label untouched. A classifier/read failure is stricter: it writes neither label nor comment. No unsafe transition is ever made.

Important Notes

• Never auto-transition labels — always suggest and let the user / pipeline confirm. The one exception is the explicit --rollup parent derivation (Step 5), which moves a parent's status:* label as the leaf-only-lifecycle rule mandates — never a leaf's, and never to status:ready.
• Idempotent updates — the [claude-sync] <milestone> prefix on the most-recent comment is the dedupe key; the rollup path uses [claude-sync] rollup.
• Comment format — use GitHub-flavored markdown (## headings, fenced code blocks). The same template is used for the JIRA path (rendered as wiki markup there); keep the markdown source canonical.
• Rollup cites the rule by slug — parent state derivation follows the leaf-only-lifecycle rule's state machine; this skill does not restate the policy.
