docs(claude): coordinate parallel work through issue assignment

[IAmJSD]

Summary

Adds an Issue assignment — claim before you work section to CLAUDE.md, identical to the one in LeanerCloud/cloud-commitments-cli#2202 and LeanerCloud/cloud-commitments-mcp#62 (which already went through several CodeRabbit rounds). Several people and their agents can then work through the issue queue in parallel without fixing the same thing twice.

• Pick the highest-priority unowned issue first (priority/p0 → p3, oldest first, then unlabelled), skipping status/blocked, status/needs-info and status/wontdo, and anything with an open PR. Includes gh queries with --limit 500.
• Claim it before writing code: self-assign, or comment Claiming: working on this without write access. Then re-check; the earliest claim wins.
• Assigned or claimed issues are off-limits. After 7 days with no activity and no PR, ask the owner. If there's no reply after 3 more days, a takeover comment supersedes only the stale owner's claim and the assignment moves over.
• PRs use Closes #N (feeds the existing label-mirroring rule). Unassign yourself and leave a note when you drop an issue.
• Larger untracked work (e.g. UI/integration) gets an assigned issue first so it shows as taken.

Docs-only change; no runtime code touched.

No closing issue: this is a contributor docs change, so there are no issue labels to mirror under the PR labeling rule.

📝 Walkthrough

CLAUDE.md adds instructions for selecting and claiming issues, handling existing and stale claims, linking pull requests to issues, and documenting work that is dropped or not yet tracked.

Changes: Issue workflow

Layer / File(s)	Summary
Issue selection and claim lifecycle CLAUDE.md	The instructions define issue selection by priority and age, require checks before claiming, and set rules for assignment, claim comments, and stale-claim takeovers. They also require pull requests to link an issue and specify how to record dropped or untracked work.

Systems and components

• observed — CLAUDE.md (service) was modified; 1 changed file maps to changed impact.

Before / after behavior

• observed — Modified behavior in CLAUDE.md: Adds a mandatory issue-selection procedure: check priorities p0 through p3 in order, oldest first, then issues without a priority label; exclude unassigned-search results labeled blocked, needs-info, or wontdo. It documents the 1,000-result truncation and requires splitting full queries into non-overlapping windows, checking comments for claims, and checking open PRs before claiming.
• observed — Modified behavior in CLAUDE.md: Adds the claim protocol: post a Claiming: marker before coding and assign yourself when possible; determine ownership from marker timestamps, where the earliest active claim wins and a later Released: ends that author’s claim. It also defines worker IDs for shared-login agents and treats markerless assignments and older free-form claims as taken.
• observed — Modified behavior in CLAUDE.md: Adds rules against working on an issue with an active claim or assignee, except that a maintainer assignment or Taking over: overrides a claim. After seven days without activity or a linked PR, contributors ask the owner; after three further days without reply, they may take over, superseding only the stale owner’s claim, and move the assignment to themselves.
• observed — Modified behavior in CLAUDE.md: Requires PRs to include Closes #<N>. Contributors dropping work without a PR must post a Released: comment and unassign themselves; if the issue is already fixed, they identify the fixing PR or commit and ask a maintainer to close it. Untracked work must first receive an issue assigned to its owner.

Synced a fix raised on LeanerCloud/cloud-commitments-go#421: the post-claim gh issue view check now prints claim comments as well as assignees, so a comment-based claim isn't missed.

[IAmJSD]

Synced from the sibling PRs: claims, takeovers and releases now use Claiming: / Taking over: / Released: marker comments, whose timestamps decide the earliest claim (assignment times aren't visible to gh issue view).

[cristim]

Independent review of 0060194: no actionable findings

Docs-only change: +83 lines in CLAUDE.md (new section "Issue assignment", inserted before "Post-push CI watcher"). Base is current origin/main (e003025, merge-base equal), so no rebase drift.

Findings (all nits, none block merge)

1. nit, CLAUDE.md step 1/2: every agent in this repo's fleet runs under one GitHub login. Two agents of the same login cannot tell which "earliest active claim" is theirs, so "if that is not you, release" is ambiguous between sibling agents. The ~/.claude/agent-comms/ bus covers same-machine agents and the section says so; cross-machine agents on one account are not covered. Suggested: one sentence saying claims from the same login are resolved through the bus or by including a worker id in the marker body.
2. nit, step 2/3: anyone, including a non-collaborator, can post Claiming: and block the issue for 10 days (7 stale + 3 reply). The text gives maintainers no override. Suggested: "a maintainer's assignment or Taking over: overrides any claim".
3. nit, step 5 and step 2: "edit your comment to Released: ..." has no command, unlike every other step. gh issue comment <N> --edit-last --body ... would work, or just post a new Released: comment, which the marker logic already supports.
4. nit, step 1: --limit 500 truncates silently if the queue grows past 500 (open issues today: 418, no:assignee also 418).
5. nit, process: the PR has no labels and no closing issue, so the "PR labeling" rule has nothing to mirror. Acceptable for a contributor docs PR, but the gap is unrecorded in the PR body.
6. nit, style: the new heading uses an em-dash. Matches existing headings in this file, so not a regression.

What I attacked

• Contradictions with the rest of origin/main CLAUDE.md: read Review gate, PR labeling, CI watcher, CR loop and Multi-Agent Communication. The new section adds a pre-work step only. Closes #<N> is consistent with the labeling rule. "bus below" resolves (Multi-Agent Communication is the last section). No conflict with the gate, watcher or CR loop.
• Commands run read-only against LeanerCloud/cloud-commitments-platform:
  • Each p0..p3 query and the no-priority query run fine (p0: 0 results; p1: 16 of 17 unassigned/unblocked; p2: 207 of 209; p3: 182 of 185; unlabelled: 7). All referenced labels exist (priority/p0..p3, status/blocked, status/needs-info, status/wontdo).
  • The marker-comment gh issue view --json comments --jq filter exits 0 on an issue with no markers (#891).
  • The gh pr list --search "<N> in:body" form works. Mutating commands (comment, edit --add/--remove-assignee) were not run; their flag syntax is valid per gh and the account has push access.
• markdownlint: markdownlint -c .markdownlint.yaml CLAUDE.md at the PR SHA exits 0 (markdownlint-cli 0.49.1 locally; the pre-commit hook pins v0.47.0, so the hook itself was not executed). Base file also exits 0.
• Sibling text: PR #2202 (cloud-commitments-cli, head 0e801b57) and PR #62 (cloud-commitments-mcp, head 2d58a84f) are both still OPEN, not merged. The added lines of this PR and of #2202 are byte-identical after substituting the repo name (diff empty); #62 differs from #2202 only in repo names. The PR body's "identical" claim holds; "already went through several CodeRabbit rounds" is true but the siblings are not merged references.
• CodeRabbit: its only actionable item (line 114, include comments in the recheck) was on d9cc70a and is addressed in the final text (the --json comments check). There are 0 inline review threads. CR's status on the head SHA is "Review rate limited" (reported as success), so CR never reviewed 0060194. Under the gate CR is optional when independent review plus local verification cover the SHA.
• Mutation/deletion probes: not applicable to prose; no code, tests or config changed.

Why checks show BLOCKED / a null check

• The only check on the head is the CodeRabbit commit status, with an empty target URL and the description "Review rate limited".
• Both workflow runs for this SHA (CI - Build & Test, pre-commit) have conclusion action_required with zero jobs: the repo's fork-PR approval policy is first_time_contributors, and the author is a first-time contributor from a fork, so a maintainer must approve the runs.
• The ruleset protect-default-branch requires the contexts CI Success and Run pre-commit hooks. Neither has reported, so mergeStateStatus is BLOCKED although mergeable is MERGEABLE and no review is required.

Gate status (origin/main Review gate)

• Independent review naming the SHA: this comment.
• Actionable findings resolved: yes (CR's one item fixed; no new actionable findings).
• CI green on the SHA: NOT met. Runs await maintainer approval; required checks not yet reported.
• Local verification: done as above (commands executed, lint clean). It is not real-account verification; no write command was executed.
• Verdict, SHA and evidence recorded on the PR: this comment. Any new commit or rebase restarts the gate.

[IAmJSD]

Thanks for the review. Addressed the nits in ffbcd3a (same change on the cli/mcp/go sibling PRs):

1. Same-login agents: each agent puts its worker id in every marker (e.g. Claiming: working on this [cc-platform-w3]) and claims are compared by worker id; same-machine agents can also use the bus.
2. Maintainer override: "A maintainer's assignment or Taking over: overrides any claim."
3. Releasing now has a command and posts a new Released: comment (latest marker counts) instead of editing.
4. --limit raised to 1000, with a note that it truncates silently and when to raise it.
5. PR body now records that there's no closing issue, so no labels to mirror.
6. Em-dash heading kept to match the file's existing headings, as you noted.

Independent review of 95ee47e: no actionable findings

Delta reviewed: 006019414d..95ee47e44c (CLAUDE.md only, +18 -9), plus the full diff against origin/main (e003025, equal to the merge-base, so no drift). Still docs-only, still within the 400-line cap.

Findings (all NON-BLOCKING nits)

1. CLAUDE.md:133,149,161: the new rule says each worker puts its worker id in "every marker", but the copy-paste examples for Released: (line 133, line 161) and Taking over: (line 149) carry no id. Under a shared login a Released: without an id cannot be attributed to a worker, so it does not end that worker's claim by the section's own rule. Suggested: add [<worker-id>] to those three examples.
2. CLAUDE.md:144-145: "A maintainer's assignment or Taking over: overrides any claim" is ambiguous. Read as "any Taking over:", it contradicts the rest of step 3, where Taking over: supersedes only the stale owner's claim and an earlier active claim still wins. Read as "a maintainer's Taking over:", it is consistent with the 7+3 day flow (the flow is the path for non-maintainers). Suggested: "A maintainer's assignment or a maintainer's Taking over: overrides any claim; everyone else uses the 7+3 day flow below."
3. CLAUDE.md:98: the reflowed line is 190 characters. Not a lint issue (see below), only a readability nit, as the neighbouring lines wrap at ~100.

What I attacked

• markdownlint (markdownlint -c .markdownlint.yaml CLAUDE.md, 0.49.1) exits 0 at this SHA. .markdownlint.yaml sets MD013: false, so the long line (and the existing 257/217-character lines) cannot fail the hook. The pre-commit hook itself (pinned v0.47.0) was not run locally; its CI job is running (below).
• 1000-result cap claim: accurate. The REST search API on this repo returns 422 Only the first 1000 search results are available for page 11 of 100 (read-only call). gh issue list --search goes through GitHub search, which has the same documented limit. I could not reproduce the silent truncation through gh itself: the repo has 590 issues in total (418 open), under the cap. --limit 1000 is therefore the right ceiling, and the "if exactly 1000, split by created: windows" advice is sound (created:<D and created:>=D are non-overlapping).
• Release comment: the new gh issue comment ... --body "Released: ..." command is valid. A later Released: from the same author/worker ends the claim under the existing "latest marker" rule, so replacing "edit your comment" is correct.
• Marker filter vs worker id: the --jq filter matches ^(Claiming|Taking over|Released): and prints split("\n")[0], so a trailing [cc-platform-w3] on the first line is printed and does not affect the match. Consistent, subject to nit 1.
• Contradictions with the rest of origin/main CLAUDE.md (gate, labeling, CI watcher, CR loop, comms bus): none; the bus reference ("same-machine agents can also use the bus below") resolves.
• Mutation/deletion probes: not applicable to prose.

Gate status (origin/main Review gate)

• Independent review naming the SHA: this comment.
• Findings resolved: no blocking findings; the three nits are optional.
• CI on the SHA: pending at the time of review. Runs 38822629087 (pre-commit) and 38822629117 (CI - Build & Test) were in progress / queued; required contexts CI Success and Run pre-commit hooks had not completed, mergeStateStatus BLOCKED. Merge only after both are green.
• Local verification: commands and lint run as above; no real-account verification and no write commands executed.
• CodeRabbit: status SUCCESS on the head; no inline threads.
• Verdict recorded on the PR: this comment. Any new commit restarts the gate.

[IAmJSD]

Thanks for the re-review. Addressed in 711a5e1 (same change on the cli/mcp/go sibling PRs):

1. Every marker example (Claiming:, Released:, Taking over:) now ends with [<worker-id>], and the rule says to leave it out only when the login isn't shared.
2. Override reworded as you suggested: "A maintainer's assignment or a maintainer's Taking over: overrides any claim; everyone else uses the flow below."
3. Steps 2, 3 and 5 rewritten so commands sit in fenced blocks wrapped under 100 columns; the only longer lines left are the --search query strings, which can't be wrapped.

Also from CodeRabbit: the post-claim check now prints assignees as well as the markers.

[cristim]

Independent delta review of 711a5e1 (previous: 95ee47e): no actionable findings

Docs-only: CLAUDE.md, +49 -33 in the delta (OLD_SHA is an ancestor of NEW_SHA). Against origin/main (e003025, equal to the merge-base, PR is MERGEABLE) the PR is still one file, within the 400-line cap.

Previous findings

#	Previous finding	Status	Evidence at 711a5e1
1	Released: / Taking over: examples lack the worker id the rule requires	RESOLVED	the Claiming:, both Released: and the Taking over: examples (step 2, 3 and 5 of the new section) all end with [<worker-id>]; step 2 states to omit it only when the login is not shared
2	"A maintainer's assignment or Taking over: overrides any claim" ambiguous vs. step 3 stale-owner takeover	RESOLVED	Now "A maintainer's assignment or a maintainer's Taking over: overrides any claim; everyone else uses the flow below." The non-maintainer Taking over: still supersedes only the stale owner's claim, so the two rules no longer conflict
3	Long reflowed line at the 1000-result paragraph	RESOLVED	Re-wrapped; remaining long lines are the --search strings, which cannot be wrapped (and MD013 is off)

CodeRabbit's two open items at the old SHA (post-claim check must show assignees; takeover precedence wording) are addressed by the same hunks. The threads are marked resolved/outdated; the two CR reviews on 711a5e1 carry no new comments.

New findings

None. Attacked the delta as new code:

• The rewritten gh issue view --json assignees,comments --jq snippet: ran the filter locally on a sample payload with jq; it prints the assignees: line and one line per marker comment, no syntax error.
• Marker regex ^(Claiming|Taking over|Released): still matches all three example bodies including the trailing [<worker-id>].
• Re-checked step 2 -> 3 -> 5 for contradictions: release (step 2 and 5) uses the latest-marker rule; takeover keeps "any other active claim posted before your takeover still wins"; the maintainer override is the only exception and is now scoped to maintainers.
• NON-BLOCKING nit only: the sentence "leave it out if the login is yours alone" is fine, but the step 2 Released: example is shown with the id while the text says it is optional; harmless.

Verification

• markdownlint -c .markdownlint.yaml CLAUDE.md (config from the PR head) exits 0. The pinned pre-commit hook itself was not run locally.
• Read-only gh commands in the section were checked for syntax (jq filter exercised above); no gh write command was executed.
• No code touched, so no Go/frontend tests apply.

Gate status (origin/main Review gate)

• Independent review naming the SHA: this comment.
• Actionable findings resolved: yes (no open actionable items from me; CR threads resolved/outdated).
• CI on the SHA: NOT green yet. pre-commit (run 38823651104) and CI - Build & Test (run 38823651141) are action_required (fork PR, awaiting maintainer approval); no checks have run on 711a5e1. This is the only thing blocking merge.
• Local real-path verification: markdownlint plus jq exercise of the documented command, labeled as such; real GitHub issue claim flow was not exercised (no write commands run).
• Verdict and SHA recorded on the PR: this comment.
• Labels: none, and no closing issue; the PR body records why, so there is nothing to mirror.

Nothing blocks merge apart from CI (approve the two action_required runs and get them green).

[cristim]

Independent delta review of a2f0e54 (previous: 711a5e1): no actionable findings

Docs-only. The delta is one hunk in CLAUDE.md (+2 -1, step 2 gh issue view filter). OLD_SHA is the parent. Against origin/main (e003025, equal to the merge-base) the PR is still one file, +109 lines, MERGEABLE.

Findings

None blocking. Previous review (711a5e1) had no open findings, so there is nothing to carry over.

NON-BLOCKING nit: the new test("claimed by"; "i") is unanchored and case-insensitive, so unrelated comments such as "Already Claimed By someone" are listed too. It only adds output lines for a human to read, and the step 2 text already says a legacy claimed by <worker> comment means the issue is taken, so over-listing errs safe. No change needed.

What I attacked

• Ran the changed --jq filter with jq on a sample payload: a Claiming: x [w1] marker, a legacy claimed by worker-7 comment, a mixed-case Already Claimed By someone, an unrelated comment, and a Released: claimed by someone else first [w2] marker. Output: the assignees: line, then exactly the marker, both legacy comments and the release, each once; the unrelated comment was dropped; exit 0. The release marker is not duplicated by the or branch.
• Parentheses and operator precedence in the new select((...) or (...)) are correct (it parsed and filtered as intended).
• markdownlint -c .markdownlint.yaml CLAUDE.md (config and file from a2f0e54) exits 0.
• The delta does not touch the claim-resolution rules, so the earlier resolutions for the worker-id examples and the maintainer-override wording still hold.

Gate status (origin/main Review gate)

• Independent review naming the SHA: this comment (head was a2f0e54 when posting).
• Findings resolved: yes, none open from me.
• CI on the SHA: GAP. pre-commit and CI - Build & Test runs 38824517778 and 38824517785 are action_required (awaiting maintainer approval); nothing has run. Merge needs these approved and green.
• Local verification: markdownlint plus a jq exercise of the changed command, labeled as such; no real GitHub claim flow or gh write command was run.
• Verdict and SHA recorded on the PR: this comment.
• Labels: none, no closing issue (PR body explains).

Nothing blocks merge apart from CI.
