fix(apply): warn when a change is ready to implement with no specs - #1783
Conversation
Apply gates on the schema's `apply.requires` (tasks) alone, so a change whose tasks file was written ahead of its specs read as ready even though it had no delta specs at all — the state `openspec validate` rejects. Apply was the one surface that green-lit a change every other surface flags, which is how agents end up implementing before the specs exist. Report it as a warning, in the text output and in `--json`, naming both ways out: write the specs, or declare `skip_specs: true`. Blocking would be a policy change; naming the gap is not. Changes that have specs, declare `skip_specs`, or are still blocked on their own required artifacts are unaffected. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

A schema with no spec-producing artifact must stay quiet, and one whose spec artifact is not called `specs` must still warn - the rule keys off the output path, not the artifact id. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

os.tmpdir() hands back the short form (C:\Users\RUNNER~1) while the CLI resolves the long one, so the assertion pinned a path that never matched on windows-pwsh. Assert the change-relative tail instead. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Apply blocks on the schema's `apply.requires` alone, so its message stopped at the first hop: a change holding only a proposal was told "Missing artifacts: tasks" while the specs `tasks` depends on were missing too. Taken literally that is an instruction to write the tracking file straight from the proposal and skip everything between — the failure reported in #834 and #869. Walk `requires` and report the whole set, in build order, as `missingPrerequisites` (text and `--json`). What apply blocks on is unchanged, and the wording leaves conditional artifacts to the schema rather than demanding them. The remedies these messages give are now CLI commands rather than the `openspec-continue-change` skill: `continue` is not in CORE_WORKFLOWS, so on the default profile the old advice named a skill that is never installed.

The main behavior looks well covered and the CI matrix is green, but the custom-schema path needs one fix before merge.
collectApplyWarnings() correctly discovers spec-producing artifacts by output path, including the test schema whose artifact ID is contracts, but the remediation text then hardcodes openspec instructions specs. For that schema the warning points the agent at an artifact that does not exist, so the advertised custom-schema support breaks at the exact recovery step. Please derive the command target from specArtifacts (or use a generic placeholder when more than one spec-producing artifact exists) and extend the renamed-artifact test to assert openspec instructions contracts --change my-change and reject the hardcoded specs command.
Separately, Closes #834 overstates this PR's scope. #834 asks for the sequence to be enforced so apply is never suggested early, while this PR deliberately keeps apply ready and emits a non-blocking warning. Relates to #834 is accurate unless the remaining enforcement request is intentionally being declined.
alfred-openspec on #1783: collectApplyWarnings() discovers spec-producing artifacts by output path, so it correctly fires for a schema whose artifact id is `contracts`, but the remediation text then hardcoded `openspec instructions specs`. That names an artifact such a schema does not declare, so the advertised custom-schema support dead-ended at the exact step meant to resolve the warning. The command now derives its target from specArtifacts: the artifact's own id when the schema declares one spec-producing artifact, and `<artifact-id>` as a placeholder when it declares several, since there is no single right answer there and a guess would read as an instruction. The renamed-artifact test now asserts the command names `contracts` and rejects the hardcoded `specs` spelling, and a new test pins the two-artifact placeholder. Verified both fail against the hardcoded string. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

@alfred-openspec Both points addressed in 1. The remediation named an artifact the schema does not declare. Confirmed and fixed. const specTarget = specArtifacts.length === 1 ? specArtifacts[0].id : '<artifact-id>';Single spec-producing artifact gets its own id; several get the placeholder you suggested, since there is no single right answer there and a guess would read as the step to run. The renamed-artifact test now asserts both directions, as asked: expect(instructions.warnings?.[0]).toContain('openspec instructions contracts --change my-change');
expect(instructions.warnings?.[0]).not.toContain('openspec instructions specs');Added a second test for the two-spec-artifact schema pinning 2. Focused suites pass (19 across |

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Assert that the warning does not select either artifact.
The current assertion only checks that the placeholder command is present. A warning that also directs the agent to contracts or schemas would pass this test, despite selecting an ambiguous artifact. Add negative assertions for both artifact-specific commands.

Reviewed 5ef9781. The warning now names the schema's actual spec artifact, uses a neutral placeholder for multiple spec artifacts, and the blocked/warning suites pass all 19 tests.
This adds `missingPrerequisites` and `warnings` to the documented `instructions apply --json` contract in docs/agent-contract.md. New fields are backward compatible, but they are new capability an agent can consume, which is a minor under semver rather than a patch. Taking the conservative direction deliberately: shipping new API surface as a patch is the violation, since a consumer pinned to a patch range would receive it without opting in. A minor costs nothing if the fields turn out to be uninteresting. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Reviewed 13b0eb1. The code remains sound, the documented additive JSON fields are correctly tracked as a minor release, all 19 focused tests pass, and CI is green.

What was wrong
Two ways
openspec instructions applytold an agent to skip the artifacts a change is supposed to be built from.1. It reported
readyfor a change with no specs at all. Apply gates on the schema'sapply.requires— forspec-driventhat istasksalone. Nothing checks thattasksown prerequisites were built, so a change whosetasks.mdwas written ahead of its specs came back ready to implement:statussays the specs are missing,openspec validate demo-changefails the change ("Change must have at least one delta … setskip_specs: true"), andarchivewarns about it. Apply was the one surface saying "go ahead" — the surface an agent reads immediately before writing code.2. When it did block, it named only the first hop. A change holding nothing but a proposal got:
Read literally, that is an instruction to write
tasks.mdstraight from the proposal — which lands you back in case 1. And the remedy was a dead end on the default install:continueis not inCORE_WORKFLOWS, so thecoreprofile never installs the skill the message named.How it was fixed
Ready-state warning.
generateApplyInstructionsnow collects warnings about the change itself. One rule today: apply is past its own gate, the schema declares spec-producing artifacts, none produced a file, and the change does not declareskip_specs: true.Blocked-state chain. Walking
requiresfromapply.requiresgives everything still to build, in build order — reported asmissingPrerequisites:Remedies that exist everywhere. Every message in this function now points at
openspec instructions <artifact> --change <name>andopenspec status --change <name>instead of theopenspec-continue-changeskill. The CLI verbs are what the skill runs, and they are there on every profile.Deliberate boundaries:
missingArtifactsstill decidesblocked, so no change that applied before applies any differently now. No deadlock risk and no new policy. Turning the no-specs warning into a hard block is a one-line follow-up, but it is a policy call and belongs to the founder, not to this PR.isSpecsArtifactPathhelper thatskip_specsalready uses — no artifact id is hardcoded, so custom schemas keep working. A schema with no spec-producing artifact getsskip_specsat change creation, so this never fires on one.designis never demanded. It is optional in practice (38 of the 83 archived changes in this repo have adesign.md) and, unlike specs, has no opt-out marker. It appears in the build-order list because the schema declares it — the wording says "build the ones this change needs … the schema says which are conditional" — and when several artifacts are left the remedy stays<artifact>rather than naming the first one, which would point atdesignas often as atspecs.--jsongainsmissingPrerequisites?: string[]andwarnings?: string[]; both documented indocs/agent-contract.md§4.6.Replication / proof
