#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 louistrue account, 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.

gh issue view <n> --json assignees      # is one of us on it
gh pr list --search "<n>"               # is anyone at all on it

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-assignee records "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".

Issue Claiming Workflow

Layer / File(s) Summary
Ownership checks
AGENTS.md
Issue checks now compare search results with linked pull requests, require assignment before coding, and repeat contributor and open-pull-request checks before pull request creation.
Session claims and collisions
AGENTS.md
Agents now record a session identifier and branch in issue comments. The earliest internal claim keeps ownership, while an outside contributor pull request takes precedence.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: 🟡 Moderate · up to 74575

The claiming procedure can still miss an existing linked pull request and allows work to continue while ownership is unresolved, which may lead to competing changes and incorrect claim decisions; these bounded correctness issues should be addressed before merging.

P2 Badge 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.

AGENTS.md reference: AGENTS.md:L184-L190

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".

@louistrue louistrue changed the title docs(agents): a shared account cannot express a claim docs(agents): the contributor check and the session check are different Aug 21, 2026
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.

gh pr list --search "<n>" is a text search, not a link lookup. I gave it as if it established a link. It matches comment bodies, so it both 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 authoritative where they disagree.

Rejected — MD046, fence the indented command block

The premise is that a configured Markdown linter reports it. There is none:

.markdownlint*           no such file
grep markdownlint package.json .github/workflows/*.yml    no matches

And AGENTS.md contains zero fenced code blocks across the whole file. Adding one would make this section inconsistent with the document rather than consistent with a linter that does not run.

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.

**The session named in the earliest claim comment decides. The other stops

"The assignee decides" is not usable here, because the assignee field holds one
shared account and cannot name a session. The claim comment can, which is the
other half of why it is required above. If no claim comment exists, ask on the
issue rather than inferring from the field.

An outside contributor's PR still takes precedence over any internal claim,
however early. They cannot see our claims and are not bound by them.

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.
