Summary

Companion to AgentWorkforce/cloud#3990 (deploy-page trigger filters).

  • --on grammar parity: the CLI's source-settings allowlist now accepts what Cloud's deploy-link parser and onboarding already emit — linear: team/project/labels/contains, jira: project/labels/contains, shortcut: workspace/team/labels/contains, gitlab: project/labels/contains/events.
  • Linear writeback: the software-factory flow now emits a Fixes <IDENTIFIER> closing reference in the PR body when the issue is a Linear ticket, so Linear's GitHub integration links the PR to the issue and transitions it on merge. (Assignment-triggered runs still depend on Cloud dispatching authored .on() handlers — not yet supported.)
  • README: documents that team= accepts the Linear team key or display name.

Test plan

  • vitest run tests/cloud-deploy.test.ts tests/canonical-software-factory.test.ts → Test Files 2 passed (2), Tests 51 passed (51)
  • npm run typecheck / npm run build / typecheck:tests (via scripts/test.sh) → clean

Note

Medium Risk
Changes deploy trigger validation and PR-opening metadata gates for a widely used example flow; mis-parsed triggers or overly strict closing-reference checks could block deployments or runs, but scope is mostly SDK/docs plus deterministic validation.

Overview
Aligns CLI flows deploy --on parsing with Cloud’s deploy wizard: gitlab is a first-class provider (project, labels, contains, events with merge_request), and Linear / Jira / Shortcut / GitHub gain the extra filter keys Cloud already emits (linear: project/labels; jira: labels; shortcut: team/labels; github: boolean reviews/checks/comments opt-outs on pull-request sources). docs/CLOUD.md and the software-factory README describe the wider grammar and that Linear team= matches name or key.

Software-factory now treats Linear like GitHub for PR write-back: it requires a TEAM-123 identifier (digits in team keys OK), appends exactly Fixes <identifier>, and fails closed before push if the line is missing, duplicated, or another closing-keyword reference appears in the body (GitHub validation uses the same stricter closing-line check). The hosted runtime SHA256 pin and flow version bump track the updated catalog flow; tests cover new --on cases and Linear metadata behavior.

Summary by cubic

Widens the --on trigger grammar so the SDK accepts what Cloud's deploy link and onboarding already emit, and writes a Linear closing reference that connects PRs to Linear issues.

  • linear gains project/labels, jira gains labels, shortcut gains team/labels, github gains reviews/checks/comments as boolean subscription opt-outs, and gitlab becomes a provider with project/labels/contains/events (merge_request as its pull-request event).
  • Linear tickets (TECH-42) now append Fixes <identifier> to the PR body, which Linear's GitHub integration reads to link the PR and move the issue on merge; the run fails closed if that line is missing or duplicated, refuses identifiers that don't match TEAM-123 form (team keys may carry digits, e.g. PLA4-42), and stops when the body carries any other closing-keyword line. A closing keyword only counts when a ticket reference follows it, so prose like "Fixed the retry loop" no longer blocks the run.
  • docs/CLOUD.md and the software-factory README document the widened grammar; the README's deploy badge now fixes only the provider since team, project and labels are edited on the deploy page, where team= matches the team name or its key.

Written for commit d7214ce. Summary will update on new commits.

Review in cubic

- cloud-deploy.ts: linear gains project/labels, jira gains labels,
  shortcut gains team/labels, github gains the reviews/checks/comments
  subscription opt-outs — matching what Cloud's deploy link and launcher
  prefilter already accept.
- software-factory: a Linear identifier (TECH-42) produces "Fixes TECH-42"
  in the PR body, the reference Linear's GitHub integration reads to link
  the pull request to the issue and move it on merge, with the same
  fail-closed count check the GitHub closing line already had.
- README: team= matches the Linear team name or its key, and the deploy
  page's ticket filters are editable.

📝 Walkthrough

Walkthrough

The changes extend deployment trigger settings for several providers and add Linear closing-reference generation and validation to the software-factory flow.

Changes

Deployment settings and Linear references

Layer / File(s) Summary
Provider trigger settings
packages/sdk/src/cloud-deploy.ts, packages/sdk/tests/cloud-deploy.test.ts, examples/software-factory/README.md
Provider settings include additional filter keys. GitHub reviews, checks, and comments accept case-insensitive true or false values. Tests cover accepted and rejected settings, and the README documents provider filters.
Linear closing references
examples/software-factory/software-factory.flow.ts, packages/sdk/tests/canonical-software-factory.test.ts, examples/software-factory/README.md
The flow generates a Fixes <identifier> line for valid Linear identifiers and checks that the pull request body contains exactly one such line. Tests cover successful generation and a duplicate-reference case that stops before push or PR creation. The README describes the reference behavior.

🔴 Linear tickets lose closing references

When a Linear ticket lacks a valid identifier, changeReference falls back to a ticket link. VALIDATE_CHANGE_METADATA skips the Linear check for that identifier, so the PR opens without a closing reference.

Learn more

The flow receives an optional issue.identifier, and its existing validation only refuses missing or malformed identifiers for GitHub tickets. The new Linear branch emits Fixes <identifier> only when the identifier matches its pattern. For other Linear inputs, the fallback emits Ticket: <url> or no reference, while VALIDATE_CHANGE_METADATA accepts the body without checking for a Linear closing line. openPullRequest then pushes and creates the PR, so the run can report success without Linear writeback.

Example: A Linear issue has source: "linear", url: "https://linear.app/acme/issue/TECH-42", and no identifier. The PR body gets Ticket: https://linear.app/acme/issue/TECH-42 instead of Fixes TECH-42; the PR still opens successfully.

Recommended fix: Refuse Linear tickets with missing or malformed identifiers before agent work, as the GitHub guard does. Also make final metadata validation reject invalid Linear identifiers independently of the closing-line count, so it cannot silently accept a missing writeback reference.

P2 Badge Reject malformed Linear identifiers before opening the PR

When a Linear-triggered input has a missing or malformed identifier, this condition is false and the validator falls through to else echo valid; meanwhile changeReference falls back to Ticket: <url-or-identifier>. The flow therefore pushes and opens a PR without the Fixes TECH-42 association that the new contract requires. Add a malformed-Linear branch, analogous to the GitHub check, so this input parks before external effects.

P2 Badge Add GitLab to the widened trigger grammar

When Cloud's deploy-link parser or onboarding emits a gitlab:project=...,labels=... source, parseTriggerSource still rejects it as an unknown provider because FLOW_TRIGGER_PROVIDERS has no gitlab member and this widened settings table has no GitLab entry. This leaves the advertised grammar parity incomplete; add GitLab and its project/labels/contains/events settings, including the intended event normalization.

Linear writeback rejects alphanumeric keys

Medium Severity

The Linear identifier check uses ^[A-Za-z]+-[0-9]+$, which rejects team keys that contain digits. Those tickets never get a Fixes closing reference, so Linear's GitHub integration does not link the pull request or transition the issue on merge.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Add GitLab to the trigger grammar.

The new allowlist covers Linear, Jira, and Shortcut, but FLOW_TRIGGER_PROVIDERS and PROVIDER_SETTINGS still omit gitlab. As a result, parseTriggerSource('gitlab:project=OPS') throws invalid_input before it reads the filter. Add GitLab to both declarations and test its promised project, labels, contains, and events settings.

- FLOW_TRIGGER_PROVIDERS gains gitlab (project/labels/contains/events with
  merge_request as its pull-request event), matching what Cloud's deploy link
  and onboarding already accept.
- A Linear ticket with a missing or malformed identifier now stops needs_human
  instead of falling through to an unlinked `Ticket:` reference; the closing
  contract (`Fixes TEAM-123` exactly once in the body) is unchanged. Team keys
  carrying digits (PLA4-42) are accepted.
- docs/CLOUD.md's `--on` grammar documents the widened settings; the canonical
  test that exercises a duplicated closing line is named for what it checks.

The badge hardcoded linear:team=ENG, which silently scoped the trigger to
a team most deploys don't have. The deploy page now renders every filter
as an editable field, so the badge fixes only the provider; team, project
and labels are set there.

- babysitter-native-extension failed in CI: hosted capability isolation
  pins the reviewed software-factory flow SHA-256, which the Linear
  identifier changes invalidated. Re-pin to the new source.
- VALIDATE_CHANGE_METADATA counted only the expected Fixes line, so a body
  carrying a foreign closing reference (Fixes OTHER-9, Closes #7) alongside
  it still validated. Count all GitHub closing-keyword lines; anything but
  exactly one — which must be the expected reference — stops before push.

Closing grep rejects ordinary summary lines

High Severity

The new closing count treats any line that begins with a closing verb plus a space as a ticket reference. Ordinary summary sentences that start with Fixed or Fix then fail after PREPARE_CHANGE_METADATA appends the real Fixes line, so a successful run never opens a pull request.

Fix in Cursor Fix in Web

Reviewed by Cursor Bugbot for commit 4f71ab5. Configure here.

"Fixed the retry loop" matched the closing count and, after PREPARE
appended the real Fixes line, left the body with two counted lines — a
successful run would never open its PR. GitHub links a closing keyword
only when a reference follows it, so the count now requires #<n>, a
KEY-<n> identifier, or a URL after the keyword. Flow source re-pinned.
