Resolve collisions by claim identity, not assignee
When two in-flight sessions use the shared account described above, the issue has only one assignee, so this rule cannot identify which session gets to continue or which one is “the other”; the later rule that the assigned person keeps the work has the same ambiguity. Key the tie-break to the session named in the earliest claim comment, or otherwise define a distinguishable owner, so both sessions cannot interpret themselves as the assignee who should continue.

Useful? React with 👍 / 👎.
Two clauses #3040 was missing, one of which I initially justified with the wrong incident and am recording correctly here. FIRST: a shared account cannot express a claim. Every one of our agents pushes and assigns as the same GitHub account, so `--add-assignee` records "somebody claimed this" and cannot record who. An assignment to your own account is therefore a claim by someone else until shown otherwise, and a claim needs a comment naming the session. This applies to our sessions only; an outside contributor has their own account and the field says what it appears to say. SECOND, and this is what #3012 actually demonstrates: the contributor check and the session check are DIFFERENT checks, and doing one does not do the other. I first wrote this up as a session collision. It was not. The issue was self-assigned at 14:12:52 and a PR for the same issue appeared 47 minutes later FROM AN OUTSIDE CONTRIBUTOR, who has no reason to know about an internal assignment and for whom the repo's existing rules already apply. The session that self-assigned never ran `gh pr list --search 3012`, and no assignee field however precise would have helped, because no session held it. Only the PR search would have. THIRD: colliding mid-flight. #3040 covers noticing before you start and after you finish, and has nothing for both sides already half-built when the claim appears, which is settled today by whoever opens a PR first and so rewards speed over ownership. The assignee decides, the other stops immediately and hands over what it has. That clause was proposed by the session that lost the race, which deliberately did not add it itself. The same session then checked my attribution and found it wrong, which is the only reason this commit says "contributor" rather than "third session".

Two review findings, both correct, and the first is a hole in the rule this file just added. I wrote "the assignee decides" one section after explaining that the assignee field holds one shared account and cannot name a session. Those cannot both be true. The claim comment can name a session, which is the other half of why it is required, so the earliest claim comment decides and "ask on the issue" is the fallback when none exists. Also states that an outside contributor's PR takes precedence over any internal claim however early, since they cannot see our claims and are not bound by them. Second: I told people to run `gh pr list --search "<n>"` as if it established a link. It is a TEXT search over comment bodies, so it misses linked PRs that never mention the number and returns unrelated ones that happen to contain it. Now framed as a reason to look rather than an answer, with the issue's linked-PR list as authoritative. Rejected the third finding, MD046 on an indented command block: there is no markdownlint config, script or workflow step in this repo, and AGENTS.md contains no fenced blocks at all, so the suggestion would make this section inconsistent with the file rather than consistent with a linter that does not run.

Ran the CodeRabbit CLI locally (the check here is a false green, its comment is the rate-limit notice). Three findings: two fixed, one rejected. Fixed — and the first one is a hole in this very rule"The assignee decides" cannot work under a shared account. I wrote that one section after explaining that the assignee field holds one shared account and cannot name a session. Those cannot both be true, and I did not notice. The claim comment can name a session, which is the other half of why it is required. So: the session named in the earliest claim comment decides, with "ask on the issue" as the fallback when none exists. Also now states explicitly that an outside contributor's PR takes precedence over any internal claim however early, since they cannot see our claims and are not bound by them.
Rejected — MD046, fence the indented command blockThe premise is that a configured Markdown linter reports it. There is none: And Not a criticism of the tool: assuming a Markdown linter is a reasonable default for a repo it has not measured. This one just has neither the linter nor the convention. |

Add an explicit linked-PR check to the repeated procedure.
gh issue view <n> --json assignees and the default gh issue view <n> output do not list open linked pull requests. gh pr list --search "<n>" performs a text search and can miss linked pull requests without a textual reference. Require inspection of the issue page or its linked pull requests before treating the contributor check as clear.

Pause and refresh ownership state during a mid-flight collision.
When no claim comment exists, the guidance only says to ask on the issue. It does not require either session to stop while ownership is unresolved. Both sessions can continue and open competing pull requests. At collision time, rerun the contributor check and inspect the linked pull request author. If no outside contributor pull request exists and no claim comment exists, require both sessions to pause until ownership is resolved.

#3040 landed the claiming rule this morning. This adds three clauses it was missing, and corrects the incident I first used to justify one of them.
What I got wrong, first
I originally wrote this up as a session collision: issue #3012 self-assigned at 14:12:52, a PR for it 47 minutes later, both under the
louistrueaccount, therefore the assignee field cannot distinguish sessions.It was not a session collision. #3043 came from an outside contributor (
BIMvoice, a User account, Petru Conduraru). They have their own account, no reason to know about an internal assignment, and the repo's existing rules already cover them: look for their PR before starting, external work takes precedence, never push to their branch.I checked this only because the session I first accused of it checked my attribution and pushed back. Getting it wrong in a rule about attribution would have been a poor place to be sloppy.
1. The contributor check and the session check are different checks
This is what #3012 actually demonstrates. The session that self-assigned never ran
gh pr list --search 3012. No assignee field, however precise about sessions, would have helped, because no session held it. Only the PR search would have.Run both, every time. Doing one does not do the other.
2. A shared account cannot express a claim
Still true, just not what happened here. Every one of our agents pushes and assigns as the same account, so
--add-assigneerecords "somebody claimed this" and cannot record who. An assignment to your own account is a claim by someone else until shown otherwise, and a claim needs a comment naming the session.Scoped explicitly to our sessions: an outside contributor has their own account and the field means what it appears to mean.
3. When you collide mid-flight
#3040 covers noticing before you start and after you finish. It has nothing for both sides already half-built when the claim appears — settled today by whoever opens a PR first, which rewards speed over ownership.
The assignee decides, the other stops immediately and hands over what it has rather than racing.
Provenance
Clause 3 was proposed by the session that lost that race and deliberately did not add it itself. That same session then checked my attribution and found it wrong, which is the only reason this says "contributor" rather than "third session".
