Closes #2034

What this changes

When a proposal declares many capabilities, the agent creating specs can go silent for a long time, apparently drafting every spec file before it writes any. Until the first file appears the user sees only a spinner, and an interrupt throws away the whole plan.

The specs instruction now tells the agent to write the files one at a time. It starts from the first capability in the proposal that has no spec file yet, says in one line which capability it's writing, and writes each file as soon as it's drafted. The docs-lab schema reference quotes the instruction, so it gets the same text.

That alone would make a re-run worse. specs reads done as soon as one matching file exists, so after an interrupted run /opsx:continue moved on to design and the missing specs were never written. openspec validate doesn't compare spec files with the proposal either, so nothing caught it. The continue skill and command now begin step 3 with a check: for each done artifact with a glob output, compare artifactPaths.<id>.existingOutputPaths with the files its instruction asks for. If some are missing, write those and stop; that counts as the run's one artifact. The check comes before the planning-complete branch, so it also catches a change where design and tasks were written after the interrupted run.

How you verified it

  • pnpm build, pnpm exec tsc --noEmit and pnpm lint pass.
  • pnpm test: 6,400 passed, 3 failed. The failures are workset.test.ts ("a launch failure carries a pasteable alternative and the manual route") and two in completion-tip.test.ts, and the same three fail on a clean main. They look environment-dependent: the workset test runs the claude binary on my PATH.
  • Parity hashes regenerated with pnpm regen:parity-hashes, and skills/ with pnpm generate:skills. Only the continue skill and command moved.

Notes

  • /opsx:ff and /opsx:propose follow the same specs instruction, so they also write spec files one at a time. They don't need the check, because only /opsx:continue picks up a change halfway through planning. If one of the others is interrupted, telling the agent to carry on in the same conversation is enough: it knows which files it has already written.
  • No new test. The skill text is pinned by the parity hashes, and the schema text by the docs parity test.
  • Written with Claude Code, model Claude Opus 5.5.

  • Ran pnpm changeset if this affects users, and committed the file
  • If a coding agent wrote this, named the agent and model in the Notes section, and verified the result myself

Summary by CodeRabbit

  • New Features
    • Spec drafting now writes each capability’s spec immediately, starting with the first missing spec and preserving existing files unless a rewrite is requested. It stops once every listed capability has a spec.
    • When /opsx:continue finds a completed artifact with required output files missing, it creates only the missing files and stops. If it’s unclear whether a file was intentionally omitted, it asks before proceeding. This check also applies to other completed artifacts that produce multiple files.

The specs instruction asked for one spec file per capability but not when
to write them, so with many capabilities the agent planned every file
before writing the first. The user saw only a spinner, and an interrupt
threw the whole plan away.

Ask the agent to start from the first capability that has no spec file,
announce each capability in one line, and write its file as soon as it
is drafted.

A glob artifact reads `done` once one matching file exists, so after an
interrupted run `/opsx:continue` would move on to `design` and leave the
missing specs unwritten. Have it check `done` glob artifacts for missing
files first and write those before anything else.

📝 Walkthrough

Walkthrough

Spec instructions now direct agents to write capability specs one at a time. The continue skill and /opsx:continue command check completed glob artifacts for missing files and handle them before proceeding through the normal status workflow.

Layer / File(s) Summary
Incremental spec-writing instructions
schemas/spec-driven/schema.yaml, docs-lab/reference/schemas/spec-driven/index.md, .changeset/specs-one-file-at-a-time.md
The spec instructions direct agents to start with the first capability that lacks a spec file, write each draft before moving on, preserve existing files unless asked to rewrite them, and stop when all listed capabilities have files.
Continue workflow checks
src/core/templates/workflows/continue-change.ts, skills/openspec-continue-change/SKILL.md, test/core/templates/skill-templates-parity.test.ts
The skill and command check completed glob artifacts for missing expected files. When files are missing, they direct the agent to write only those files and stop; when omission intent is unclear, they direct the agent to ask the user. Parity test hashes are updated.

Comment thread src/core/templates/workflows/continue-change.ts
The partial-artifact check in /opsx:continue compared the existing files
with what the artifact's instruction asks for, but fetched that
instruction only after finding a gap. Status JSON doesn't carry the
instruction, so the agent had nothing to compare against. Get the
instruction and read the dependencies first, and for spec-driven's specs
name the proposal as the source of the expected files.

Comment thread skills/openspec-continue-change/SKILL.md
Expected spec paths are relative to the change, but
`existingOutputPaths` holds absolute paths, so comparing them directly
could report an existing spec as missing and send it to be rewritten.
Resolve each expected path against `changeRoot` first.

No blocking findings from this pass.

I specifically checked the issue #2034 failure path against the artifact graph/status contracts:

  • specs/**/*.md still reads as complete once any matching file exists, so the repair does need to happen before /opsx:continue follows the planning-complete or next-ready branches.
  • This PR places the partial-glob check before that branch and tells the agent to load the artifact instructions/dependencies before comparing expected files with artifactPaths.<id>.existingOutputPaths.
  • For spec-driven specs, the expected-file source is concrete enough: proposal capabilities map to specs/<capability-path>/spec.md, resolved from changeRoot, and the instruction says to preserve existing files.

Residual risk: this is still an agent-instruction fix rather than a machine-readable expected/missing output contract, so arbitrary custom-schema glob artifacts remain heuristic unless their instructions make the expected files clear. That seems acceptable for this patch since the concrete bug is the default spec-driven specs artifact.

I did not run the full suite in this pass; the isolated checkout had no node_modules. I did run git diff --check origin/main...HEAD, and it was clean.

Approved. The user job is clear: show progress while drafting multi-capability specs and preserve partial work across interruptions. The instruction change is the smallest viable fix, the recovery check runs before continue advances the workflow, existing files are preserved by path identity, the canonical spec-driven docs are updated, and CI is green. The broader custom-glob case remains intentionally heuristic. Because this changes docs-lab, @TabishB still needs to give the required final docs review before merge.
