Every issue turn carried a claim-time snapshot of the same agent's other in-flight tasks, scoped only by (agent, workspace) and capped at five. The scope had no relatedness filter, so the list answered "what else is this agent running right now", not "what else touches the code you are about to change". Measured over one day of runs on this workspace: the block was injected 78 times across 30 runs, listing 96 distinct (current issue, sibling) pairs, and not one pair shared a PR, a branch, or an issue family. `run-messages` was invoked zero times off it. Meanwhile the day's one genuine overlap — a PR review pushing to server/internal/metrics/pricing.go and a concurrent change to the model catalog next to it — was never paired, because overlapping in time is not the same as overlapping in code. The duplicate-run defect this shipped with (#6947) is fixed by shouldSuppressActiveSelfAssignment, which stops a second run on the same (issue, agent) at the server. Once that holds, the block can only ever list a DIFFERENT issue, so it was structurally unable to help with what it was added for. #7922 then gave the coordination question a correct answer — `issue runs --active` / `--siblings`, cross-agent, family-scoped, and read at the moment it is asked — which is the same information as a pull instead of a per-turn push. Removed end to end rather than hidden behind a flag: the prompt block, the claim payload field on both sides of the wire, and ListActiveSiblingIssueTasks. The field was `omitempty` and the daemon already rendered nothing for an empty list, so old and new server/daemon pairs stay compatible in both directions; nothing outside server/ ever read active_sibling_runs. Kept: the self-assignment suppression and its tests, `--no-start`, `issue run-messages`, and `issue runs --active/--siblings`.

|

// - It calls classifyTask (runtime_config_kind.go) to pick one of five
|
||
// task kinds, then composes the brief from the per-section writers
|
||
// below.
|
||
// - Each section is its own writer so the matrix of "which kind gets
|
||
// which section" lives at a single dispatch site.
|
||
//
|
||
// The brief applies two orthogonal optimisations:
|
||
//
|
||
// 1. Section gating per task kind — quick-create / chat / autopilot
|
||
// skip sections they have no use for (Mentions, Comment Formatting,
|
||
// Issue Metadata, Sub-issue, ...).
|
||
// 2. Per-section prose compression — Available Commands, Issue
|
||
// Body Formatting, Metadata, Mentions, Sub-issue Creation,
|
||
// Comment Formatting, Always Use CLI, Background Task Safety, Task Initiator,
|
||
// Repositories, Output are all tightened. Test-asserted phrases either
|
||
// survive verbatim or are renegotiated to new semantic anchors in the

|
||
//
|
||
// MUL-5223: the external-work boundary alone did not stop agents from
|
||
// blocking on CI. Two holes are closed here. First, the boundary was
|
||
// stated as a concept while the section's only concrete "how to wait"
|
||
// example was a blocking foreground call — and `gh pr checks --watch` is
|
||
// exactly that shape, so watching CI read as compliant. Named tool-shape
|
||
// bans replace the inference. Second, the "unless acceptance criteria
|
||
// require it" escape was being satisfied by the repo's own merge
|
||
// requirements ("CI must pass before merge"), so the section now says
|
||
// branch protection is not the agent's acceptance criterion, and gives
|
||
// the replacement hand-off phrasing so the urge to prove quality lands
|
||
// on local test output plus a PR link instead of on a wait.
|
||
//
|
||
// The ban is scoped, not absolute: an explicitly requested CI result is
|
||
// still reachable, and it names the one executable way to collect it
|
||
// (a single foreground blocking watch inside the same turn). Enabling
|
||
// auto-merge is not a wait and stays allowed — only waiting for it to
|
||
// land is banned.
|
||
//
|
||
// MUL-5274 adds one narrow lifetime exception: a user-requested local
|
||
// development/test service may be handed off after its readiness and cleanup
|
||
// contract are complete. It is not a future result or wakeup. The brief keeps
|
||
// this separate from tests, builds, monitors, and CI polling, which remain
|
||
// run-owned until their result is collected. The brief states only the
|
||
// handoff contract (lifecycle independence, durable logs, cleanup handle);
|
||
// how to detach is the Local Dev Environment skill's concern, not the brief's.
|
||
//
|
||
// Paragraph order: the CI exception lives INSIDE the boundary paragraph
|
||
// (one "The one exception" occurrence, count-guarded in the tests), and the
|
||
// persistent-service paragraph closes the section. A former scoping sentence
|
||
// ("The rules above apply only to work owned by the current run") stays
|
||
// dropped: the boundary paragraph carries its own scope ("are not
|
||
// run-owned").

// a frontier model derives from the platform fact were deliberately dropped

// wait/collect split rule, the persistent-service scope bullet, the

// auto-merge and snapshot elaborations. Their pins were retired in the same

// change. The incident history above (MUL-5223, MUL-5274, MUL-4091) remains

// the WHY for what stays: the named --watch/watch/poll ban and merge-gate

// condition triggers the model is executing the numbered list, and a rule
|
||
// outside the list does not fire (the pre-MUL-6417 opening write was
|
||
// reliable precisely because it was an explicit step). Same incident killed
|
||
// the "asked to research stays todo" example from the no-write bullet: that
|
||
// run's work WAS research toward its own issue's ask, so the example
|
||
// pattern-matched the exact case it was never meant to cover. Ancillary is
|
||
// now defined by output alone — the turn produced none of the issue's own
|
||
// deliverable. No activity-word list survives in EITHER direction: Elon's
|
||
// review on #7295 caught "review" still sitting in a skip-list (the same
|
||
// incident queued to replay on a review-the-PR issue), and J's review
|
||
// caught the positive form-list that replaced it ("code, research, a
|
||
// design, ...") — a whitelist reads as exhaustive, so a triage or
|
||
// reproduce-the-bug turn would not find itself in it. What remains is the
|
||
// criterion plus one never-decides sentence, placed inside step 3 because
|
||
// that is the position that fires. The exit-side check is anchored inside

||
// step 5 for the same reason, and the step-3 skip is scoped to the
|
||
// in_progress CATEGORY so a custom status like Planning already counts as
|
||
// recorded once MUL-6460 puts the catalog in front of agents.
