Summary

Replaces the standalone ~/.config/cmux/bin/crew-pr-stages bash poller with an opt-in pr-stage-sync step inside groundcrew's own watch loop (src/commands/prStageSync.ts), so the orchestrator — not a separate process — keeps each task workspace's cmux sidebar in sync with its pull request's review stage.

  • Opt-in, off by default: cmux.prStages: { enabled, labels: { selfReviewed, tested } } in Config/ResolvedConfig (defaults self-reviewed/tested). Inactive unless the resolved workspace backend is cmux; other adapters no-op. See crew.config.example.ts and docs/configuration.md.
  • Stage/ticket derivation ported 1:1 from the bash poller's jq filters into pure functions (src/lib/prStageRules.ts), carrying over all 17 stage fixture cases and 8 ticket fixture cases as unit tests. Rule order is unchanged: merged → closed → ci_failing → ci_running → my_review (draft or missing self-review label) → needs_testing → changes_requested → ready_to_merge → peer_review.
  • One batched GitHub GraphQL call per tick (src/lib/pullRequestDetails.ts) covering every tracked PR via aliased resource(url:) fields with urls passed as URI! variables, never string-interpolated — bounded by the tick's abort signal/timeout.
  • PR resolution prefers the task's worktree branch (existing pullRequests.ts helpers) over cmux's own PR detection.
  • Change-only writes: each tick reads current cmux status first and only calls set-status/clear-status for fields whose desired value actually changed. A workspace is only cleared when its task genuinely has no PR — never on a lookup failure, which is treated as "skip, try again next tick."
  • Best-effort, isolated from the watch loop: any failure (listing workspaces, one workspace's PR lookup, one workspace's status write) logs logEvent("pr-stage-sync", { outcome: "error", reason }) and is contained to that workspace/tick; it never aborts the orchestrator's other tick steps. Entry + terminal log per pass, with written/cleared/skipped counts.
  • New CLI surface (src/commands/stage.ts): crew stage label-add <pr-url> <label> / crew stage label-remove <pr-url> <label> (validates the label against the two configured gating labels and the PR URL shape, creates the label in the repo on first use with the bash poller's colors — self-reviewed 5319E7, tested 0E8A16 — via gh pr edit --add-label/--remove-label), and crew stage refresh to run one sync pass on demand. Wired into cli.ts and completions.ts.

Design decisions

  • Config shape: nested under a new top-level cmux key (cmux.prStages) rather than flattening into orchestrator or workspace, since this is cmux-adapter-specific and other workspace kinds (tmux/zellij) have no equivalent. isCmuxAdapterActive() gates every pass so a misconfigured workspaceKind never writes stale cmux status.
  • Change-detection: reads the four managed keys (crew_stage, crew_ticket, crew_labels, crew_poller_heartbeat) via readCmuxStatus before writing, diffing against the freshly-derived desired values; this mirrors the bash poller's own diff-before-write behavior and keeps set-status calls (and cmux IPC traffic) proportional to actual change, not task count.
  • Heartbeat (crew_poller_heartbeat, priority -12) is written once per tick only on the watcher's own workspace ($CMUX_WORKSPACE_ID), matching the bash poller's contract so either implementation's heartbeat is a valid liveness signal during the migration.

Cmux sidebar rework (contrib/cmux/)

Ports Jason's reworked custom cmux sidebar into contrib/cmux/groundcrew.swift, replacing the
previous flat, title/directory-parsed row list with one grouped by PR review stage:

  • Stage sections (Needs you → Your review → CI failing → Changes requested →
    Needs testing → Ready to merge → Working → Waiting → Peer review →
    Stage unknown/Open PRs → Done) replace the single flat task list. A row's stage prefers live
    agent signal (waiting on you, or still executing) over a possibly-stale synced crew_stage, so an
    actively-worked row never shows a stale badge.
  • Compact two-line rows: title + a horizontal, deduped, per-agent icon strip (color/opacity
    encode state; brand icon with an amber ring for needs_input) on line one, ticket/PR pills on
    line two. The per-row stage badge, directory line, per-agent text row, and native status line are
    all gone — that information now lives in the section header and the icon's own styling.
  • Ticket id from crew_ticket, not parsed: the sidebar reads the crew_ticket status
    pr-stage-sync writes instead of re-deriving it every render from the title/directory with a
    52-call character-strip loop. Since a custom sidebar may read crew_ticket independent of PR-stage
    sync, pr-stage-sync now writes it for every matched cmux task workspace regardless of
    cmux.prStages.enabled — runOnce splits into the existing gated full sync and a new
    ticket-only path (syncTicketsOnly) that writes no stage, labels, or heartbeat when the opt-in is
    off.
  • Context-menu label toggles and refresh now call crew stage label-add/label-remove/refresh
    from the groundcrew checkout (same cwd pattern as the existing Cleanup workspace action),
    replacing the retired ~/.config/cmux/bin/crew-pr-stages script. The menu's label wording is
    hardcoded to the default label names; contrib/cmux/README.md documents the limitation if
    cmux.prStages.labels is overridden.
  • Feature-off degradation: when no workspace carries a crew_poller_heartbeat at all (the only
    way that happens is cmux.prStages never having run for any tracked task), the sidebar treats this
    as "off," not "broken" — it hides the "PR stages stale" caption and renders stage-unknown PR rows
    under "Open PRs" instead of "Stage unknown." A present-but-outdated heartbeat still means stale, as
    before.
  • Repo conventions restored on top of the installed file: prLinkTarget() defaults back to
    "github" (the installed copy had it set to "linear-app"), and the checkout path uses the
    __GROUNDCREW_DIR__ placeholder install.sh substitutes (both crewStagesCwd() and the Cleanup
    action), rather than a hardcoded path.
  • Tests (contrib/cmux/tests/, not wired into npm run verify — they need a live cmux checkout
    and Swift toolchain): the installed sidebar's 5 Swift Testing suites (38 cases), adjusted for the
    new crew stage command strings and the feature-off mode. Ran clean against this PR's
    contrib/cmux/groundcrew.swift via swift test --filter GroundcrewSidebar from a cmux checkout
    (38/38 passing), with one case deliberately broken and re-run to confirm it can fail. Render-cost
    bench (GroundcrewSidebarRenderBenchTests, median over 10 parse+eval passes of the same
    12-workspace snapshot cmux re-renders every 1s) came in at 270ms for the ported file vs. 271.5ms
    for the currently-installed file — on par, well under the budget where piled-up renders blank the
    sidebar.
  • Jason's installed ~/.config/cmux/sidebars/groundcrew.swift was read as source material only and
    was not modified; he'll cut over to the repo's version separately after review.

Test plan

  • node --run test — 2361 tests passing across 99 files, 100% statements/branches/functions/lines coverage (v8).
  • node --run verify — architecture:check, build, cpd, format:check, knip, lint, markdown:lint, syncpack:lint, test all green.
  • Live-compared against the real standalone poller from a cmux-spawned shell: ran node --run crew -- stage refresh (via a temporary GROUNDCREW_CONFIG override with cmux.prStages.enabled: true, layered onto a copy of the real config — the real ~/.config/groundcrew/crew.config.ts was never edited) against Jason's live cmux, then ran the standalone crew-pr-stages once immediately after. Across 3 sampled task workspaces, both tools agreed exactly on crew_stage/crew_ticket (including a workspace with no PR, correctly left unset by both). No label-add/label-remove was run against any real PR, and the running poller loop/orchestrator watcher were left untouched throughout.
  • Re-ran node --run crew -- stage refresh live after this change and confirmed the real cmux adapter accepted the write (crew_poller_heartbeat updated on the invoking workspace) — the new syncTicketsOnly path shares its status-write helper with the already-live-verified syncOnce path.
  • contrib/cmux/tests/ Swift suites (38 cases) run clean against contrib/cmux/groundcrew.swift from a cmux checkout, plus the render-cost bench; see above.

Replaces the standalone crew-pr-stages bash poller with an opt-in
pr-stage-sync tick step. Each watch tick batches one GitHub GraphQL call
for every tracked PR, derives crew_stage/crew_ticket/crew_labels from the
same rules the bash poller used, and writes only changed cmux sidebar
fields. Adds `crew stage label-add/label-remove/refresh` to manage the
two gating labels and trigger a pass on demand.

📝 Walkthrough

Walkthrough

Adds opt-in cmux pull-request stage synchronization. The synchronizer derives stage, managed-label, and ticket values for matched tasks and writes them to cmux workspace status. The cmux sidebar groups tasks by stage and adds label-toggle and refresh actions.

Changes

Pull-request stage synchronization

Stage configuration and defaults
src/lib/config.ts, src/testHelpers/cmuxConfig.ts, crew.config.example.ts, docs/configuration.md, src/lib/config.cmuxPrStages.test.ts, src/lib/config.paths.test.ts, src/commands/*test.ts, src/lib/*test.ts, src/lib/adapters/linear/*test.ts
Adds optional cmux.prStages settings, default labels, and validation. Updates the example and configuration reference. Resolved-config test fixtures now include cmux defaults.
Pull-request details and stage rules
src/lib/pullRequestDetails.ts, src/lib/pullRequestDetails.test.ts, src/lib/prStageRules.ts, src/lib/prStageRules.test.ts, src/lib/pullRequests.ts, src/lib/pullRequests.test.ts
Adds batched GitHub GraphQL pull-request lookup and derives stages, managed labels, and ticket identifiers. Adds a pull-request lookup that propagates command failures.
cmux status synchronization
src/lib/cmuxAdapter.ts, src/lib/cmuxAdapter.test.ts, src/lib/cmuxStatusFields.ts, src/lib/cmuxStatusFields.test.ts, src/commands/prStageSync.ts, src/commands/prStageSync.test.ts, src/commands/orchestrator.ts, src/commands/orchestrator.test.ts
Adds cmux workspace summaries and status-field operations. The synchronizer matches workspaces to tasks, resolves pull requests, updates sidebar fields, and runs after the cleaner on each watch tick.
Stage-label commands and CLI wiring
src/commands/stage.ts, src/commands/stage.test.ts, src/cli.ts, src/commands/completions.ts, README.md, docs/commands.md
Adds label-add, label-remove, and refresh. Label commands validate configured labels and pull-request URLs, add or remove labels, and run a sync pass.
cmux sidebar and regression suites
contrib/cmux/groundcrew.swift, contrib/cmux/README.md, contrib/cmux/tests/*, src/contribCmux.test.ts
Groups sidebar tasks by stage and displays ticket and PR links with deduplicated agent icons. Adds context-menu actions, stage freshness handling, and sidebar interpreter tests.

Important

Three correctness gaps need addressing: lookup failures erase saved stages, orchestrator dry runs write cmux status, and label removal bypasses URL validation.

Reviewed changes — Reviewed the complete initial PR, its watch-loop integration, real PR discovery helper, and CLI behavior.

  • Stage synchronization: Adds opt-in cmux configuration, workspace matching, branch PR discovery, batched GraphQL details, changed-field writes, and heartbeat updates.
  • Stage rules: Adds pure stage, ticket, and managed-label derivation with fixture coverage.
  • Operator commands: Adds label creation/application/removal, on-demand refresh, completions, and documentation.
  • Validation: node --run verify passed all checks, including 2,348 tests and 100% coverage; isolated reproductions confirmed the three inline findings without external mutations.

Comment thread src/commands/orchestrator.ts
Comment thread src/commands/stage.ts
Preserves saved crew_stage/crew_labels when PR discovery itself fails
(network/auth error), instead of conflating that with a confirmed
"no PR" and clearing them. Adds findPullRequestsForBranchOrThrow so
pr-stage-sync can tell the two apart; the shared display-oriented
findPullRequestsForBranch is unchanged for its other callers.

Honors the orchestrator's --dry-run in the per-tick sync, so it no
longer writes cmux status during a dry run (crew stage refresh is
unaffected — it always writes). Validates the PR URL before
label-remove, matching label-add.

Reviewed changes — Reviewed the fixes in 9d4deac since the prior Pullfrog review at 9388d2a, with the complete PR diff as context.

  • Preserved saved PR status: Separated failed discovery from confirmed empty results using a throwing lookup helper and per-workspace failure tracking.
  • Honored dry runs: Skipped adapter access and status/heartbeat writes during orchestrator dry runs while retaining explicit refresh behavior.
  • Validated removal targets: Applied full PR URL validation before label removal, with a regression test preventing gh calls for invalid targets.

Ports Jason's reworked sidebar (stage sections, compact two-line rows, a
horizontal agent-icon strip, and label toggles in the context menu) into
contrib/cmux/groundcrew.swift, restoring the repo's own conventions on top:
prLinkTarget() defaults back to "github", and the checkout path uses the
__GROUNDCREW_DIR__ placeholder install.sh substitutes (crewStagesCwd() and
the Cleanup action), instead of a hardcoded path.

The context menu's label toggles and "Refresh stages" action now call
`crew stage label-add/label-remove/refresh` from the groundcrew checkout,
replacing the retired standalone crew-pr-stages script.

pr-stage-sync now writes crew_ticket for every matched cmux task workspace
regardless of cmux.prStages.enabled, since the sidebar reads crew_ticket
unconditionally -- splitting runOnce into the gated full sync and a new
ticket-only path (syncTicketsOnly) that writes no stage, labels, or
heartbeat. The sidebar treats "no crew_poller_heartbeat anywhere" as
feature-off rather than stale: it hides the stale caption and renders
stage-unknown PRs under "Open PRs" instead of "Stage unknown".

Brings the Swift regression suite into contrib/cmux/tests/, adjusted for
the new command strings and the feature-off mode, with a README on running
them against a cmux checkout. They're intentionally not wired into this
repo's npm verify, since they need a live cmux checkout and its Swift
toolchain.

Three new sidebar integration gaps affect on-demand refresh, ticket actions for manual launches, and custom gating labels.

Reviewed changes: Reviewed d0bf9e9 since the prior Pullfrog review at 9d4deac, with the complete PR diff as context.

  • Regrouped task rows: Replaced the flat sidebar with stage sections, compact ticket/PR rows, and deduplicated agent icons whose live state takes precedence.
  • Moved ticket reads: Replaced sidebar title/directory parsing with crew_ticket, and added ticket-only synchronization when PR-stage polling is disabled.
  • Integrated operator actions: Added sidebar label toggles and refresh through crew stage, plus heartbeat-driven stale/off presentation.
  • Expanded coverage: Added Swift interpreter suites and a render benchmark, updated source guards, and covered ticket-only synchronization failures.

Validation: node --run verify passed all checks, including 2,361 tests across 99 files and 100% coverage. Isolated production-code checks and execution of the shipped Swift value-helper bodies confirmed the findings without external mutations; the full cmux interpreter suites were not rerun because they require the separate cmux package checkout.

Comment thread contrib/cmux/groundcrew.swift
Comment thread contrib/cmux/groundcrew.swift
The heartbeat write only ran on $CMUX_WORKSPACE_ID, so when the watch loop
runs outside a cmux-spawned shell, cmux.prStages could be fully enabled and
writing correct crew_stage values with no heartbeat anywhere -- which the
sidebar's new feature-off detection would misread as PR-stage sync having
never run. writeHeartbeat now falls back to the first matched task
workspace, in its own try/catch so a heartbeat failure never masks a more
specific reason from an earlier step in the same pass.

Also corrects contrib/cmux/README.md's description of the context-menu
label toggles with overridden cmux.prStages.labels names: they fail
outright (the sidebar's "has this label?" check and the label name it
sends are both hardcoded to the defaults, never read from crew_labels),
not "still toggle the configured label" as previously stated.

No new findings in 054d77e. Approval remains withheld because the existing actionable review threads are still unresolved.

Reviewed changes: Reviewed d0bf9e9 → 054d77e since the prior Pullfrog review, with the complete PR diff as context.

  • Added heartbeat fallback: Used the first matched task workspace when CMUX_WORKSPACE_ID is absent, while preserving the invoking-workspace target when it is set.
  • Isolated heartbeat errors: Reported heartbeat_write_failed without replacing an earlier lookup or status-write failure reason.
  • Expanded regression coverage: Added fallback and heartbeat-failure tests and updated the unchanged-field assertion for the new heartbeat write.
  • Corrected label documentation: Documented that sidebar toggles use default label names and fail for overridden roles, while refresh and direct configured-label CLI commands remain available.

Validation: node --run verify passed all checks, including 2,363 tests across 99 files and 100% coverage. An isolated production-code check confirmed the missing-environment fallback and unchanged temporary-action heartbeat placement; the separate cmux Swift interpreter suites were not rerun because they require an external cmux checkout.

…aleness

Two pullfrog findings on the sidebar rework (PR #409, commit d0bf9e9):

- crew_ticket was only ever written by an orchestrator tick (full sync or
  the tickets-only pass), so a workspace launched via `crew start`/`crew
  open --task`/`crew resume` showed no ticket pill or Cleanup action until
  the watch loop ran at least once. cmuxAdapter.ts now writes crew_ticket
  from the task id the moment a workspace is created, best-effort like its
  existing agent/task status painting, covering every launch path in one
  place since they all funnel through workspaces.open.

- writeHeartbeat preferred $CMUX_WORKSPACE_ID over a matched task
  workspace. That's fine for the long-running watch loop, but `crew stage
  refresh`/`label-add`/`label-remove` run the same sync pass from a cmux
  Action's own ephemeral workspace, which closes right after the command
  exits — taking the heartbeat with it and making a successful on-demand
  refresh look stale on the next render. The sidebar's staleness check
  scans every workspace for any recent heartbeat, so it doesn't matter
  which task workspace carries it; flip the priority to prefer a matched
  task workspace, falling back to CMUX_WORKSPACE_ID only when none exist.

Also splits workspaces.test.ts's "workspaces.open (cmux)" describe block
into its own file (workspaces.open.cmux.test.ts), matching the existing
worktrees.test.ts/worktrees.open.test.ts split convention, since the new
crew_ticket coverage pushed the original file past the 2200-line lint cap.

Important

One new ticket-value regression remains: launch-time initialization publishes task slugs as Linear ticket IDs instead of using the synchronization path's ticket derivation.

Reviewed changes: Reviewed 054d77e to c6c2087 since the prior Pullfrog review, with the complete PR diff as context.

  • Moved heartbeat storage: Preferred a matched task workspace over the invoking workspace so freshness survives successful sidebar action closure.
  • Initialized ticket status: Added best-effort crew_ticket writes to the common cmux workspace creation path used by start, open, and resume.
  • Shared ticket constants: Moved the ticket status key and priority into cmuxStatusFields.ts for launch and synchronization callers.
  • Updated regression coverage: Added launch-time ticket/error tests, asserted task-first heartbeat targeting, and extracted cmux creation tests into their own file.

Validation: node --run verify passed on rerun, including 2,366 tests across 100 files and 100% coverage; the first attempt encountered an unrelated Vitest teardown rejection in status.test.ts. Isolated built-production checks reproduced the ticket mismatch and confirmed on-demand heartbeat retention with polling disabled and the action workspace removed. The separate cmux Swift interpreter suites were not rerun because they require an external cmux checkout.

Comment thread src/lib/cmuxAdapter.ts Outdated
…raw task slug

CodeRabbit and pullfrog both flagged the same bug on commit c6c2087's
launch-time crew_ticket write, independently: it wrote spec.name (the raw
task id, e.g. "feature-tg-123" or a lowercase "team-1") verbatim, while
prStageSync's sync loop derives the field from title/cwd via deriveTicket
(prefix-NUMBER matching, uppercased). The two disagreed for any task whose
id isn't already a clean uppercase TICKET-123 — flickering to a different
value on the first sync tick, or worse, painting a bogus Linear link for a
ticketless branch slug that deriveTicket would correctly leave unset.

cmuxAdapter.ts now derives the same way the sync loop does, using the
spec's displayName/name and cwd, and skips the write entirely (rather than
clearing a key that was never set) when no ticket can be derived.

✅ No new issues found.

Reviewed changes: Reviewed c6c2087 to ce309d3 since the prior Pullfrog review, with the complete PR diff as context.

  • Reused ticket derivation: Initialized crew_ticket from the workspace creation title and directory using the same deriveTicket function as synchronization, rather than publishing the raw task slug.
  • Skipped ticketless writes: Left fresh workspaces without a derived ticket free of both ticket writes and unnecessary clears, while retaining best-effort error handling.
  • Added regression coverage: Asserted the exact ticket value for a multi-segment branch slug and the absence of status writes for a ticketless workspace.

Validation: node --run verify passed all checks, including 2,368 tests across 100 files and 100% coverage. Isolated production-adapter checks also passed for lowercase tickets, multi-segment slugs, ticketless slugs, display-title fallback, and directory precedence. The separate cmux Swift interpreter suites were not rerun because they require an external cmux checkout.

The amber selection dot and background tint were indistinguishable from
the "Needs you" stage color, so the active row was invisible at a
glance. Selection now gets its own accent (pink fill, outline, bold
title) that no stage color uses, and unselected rows dim slightly so
the selected one reads as "lit up" rather than merely less dim.

…tion (#419)

## Summary

- Main is red after #409 merged: the coverage gate reports
`prStageSync.ts` at 90.47% functions (lines 164-165). vitest 5.0.3
(#418, merged just before) counts the `??` fallback callbacks in
`selectTrackedPullRequest` as separate functions, and no test reached
the merged or closed branches. Adds table cases for a merged PR
preferred over a closed one, and a closed-only PR.
- The cmux sidebar's stale-stage caption still named the retired
standalone poller. It now reads "PR stages stale — is crew run --watch
running?" (sidebar, its tests, and README).

## Verification

- `node --run verify` passes locally on node 24.14.1, coverage back to
100%.
- Swapping the merged/closed preference in `selectTrackedPullRequest`
fails the new merged-over-closed case.
