Closes #1959

Verify looked for an implementation of every ### Requirement: in a change's delta specs, whichever section it sat under. So a requirement under ## REMOVED Requirements that the change had removed correctly came back as CRITICAL "Requirement not found", and the report told the agent to implement it. Following that advice puts back exactly what the change just took out.

Verify now notes the delta section of each requirement before checking it. ADDED and MODIFIED requirements get the same checks as today. A REMOVED requirement is checked the other way round: finding no implementation is the expected result, and it only becomes CRITICAL ("Removed requirement still implemented") while the behavior is still in the code, with a pointer to the Migration note if there is one. A RENAMED entry only changes a name, so its old name is no longer reported as missing. Implementation mapping and scenario coverage skip removed requirements, since there is nothing left to cover.

Archive and sync already treat each section on its own terms, so this brings verify in line with the rest of the loop. It is a text change to the verify skill and command templates only; the CLI is untouched.

Also in this PR

The committed skills/openspec-verify-change/SKILL.md is regenerated and the parity hashes are updated. openspec/specs/opsx-verify-skill/spec.md gets two scenarios for removed and renamed requirements, and "Missing implementation" is narrowed to ADDED or MODIFIED. A patch changeset is included.

Testing

A new test/core/templates/verify-change-delta-operations.test.ts checks both the skill and the command body. All 10 cases fail against the current template and pass with the fix. Build, lint, openspec validate --specs --strict and the full suite (5832 tests) pass locally.

Heads up

#1732 edits the lines just above Spec Coverage in the same file. The two changes do not overlap in meaning, but whichever lands second will need a small rebase, and I'm happy to do it if that is this one.

Summary by CodeRabbit

  • Bug Fixes
    • Verification now treats added and modified requirements as implementation checks, while removed requirements pass when their behavior is no longer present and are flagged if it remains.
    • Renamed requirements are checked against their baseline behavior under the new name. Their former names are no longer incorrectly reported as missing; missing baseline behavior is flagged.
    • Implementation mapping and scenario coverage apply only to added and modified requirements. For readable changes containing only removals or renames, these checks are marked not applicable.

Verify walked every "### Requirement:" in the delta specs and looked for
an implementation of each one, whatever section it sat under. A REMOVED
requirement that the change had removed correctly came back as CRITICAL
"Requirement not found", with a recommendation to implement it. An agent
that follows the report puts back the behavior the change just deleted.

Verify now notes the delta section of each requirement first. ADDED and
MODIFIED keep the existing checks. REMOVED is checked the other way
round: finding nothing is the expected result, and it is only critical
while the behavior is still in the code. RENAMED only changes a name, so
the old name is not reported as missing. Scenario coverage skips removed
requirements, since there is nothing left to cover.

Archive and sync already handle each section on its own terms; verify
was the one step in the loop that did not.

Closes Fission-AI#1959

📝 Walkthrough

Walkthrough

The verification specification, skill guidance, and generated templates now distinguish requirements by delta operation. REMOVED requirements are flagged only when their behavior remains implemented. RENAMED requirements are checked against baseline behavior, rather than treated as missing by their old names. Tests cover both templates and the committed mirror.

The Spec coverage, Requirement implementation mapping and Scenario
coverage scenarios still told the verifier to check every requirement
in the delta specs, which contradicts the Removed requirement scenario
added in the previous commit. A verifier following them would repeat
the Fission-AI#1959 failure.

@coderabbitai good catch, fixed in 0fa39af. The three general scenarios (Spec coverage, Requirement implementation mapping, Scenario coverage) now cover ADDED and MODIFIED requirements only, and Spec coverage points to the Removed and Renamed scenarios for the other two sections.

@ryandemelo Thanks. The scenario scope now matches the delta-operation behavior. The dedicated REMOVED and RENAMED scenarios make the exceptions explicit.

Resolve the parity-hash conflict with Fission-AI#1732 by regenerating the three
verify hashes from the merged templates.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
With Fission-AI#1732 merged, a change whose delta specs only remove or rename
requirements left Requirement Implementation Mapping and Scenario
Coverage with nothing to check. The "no usable requirements" rule then
marked them not verified, so verify never reported the change ready,
the exact case Fission-AI#1959 describes. Those two checks are now not applicable
when the readable delta specs hold REMOVED or RENAMED requirements and
no ADDED or MODIFIED ones. An empty or unparseable delta still marks
them not verified.

Keyword matches in openspec/ artifacts, docs, or code that serves only
the Migration note or an ADDED requirement are no longer evidence by
themselves that a removed requirement is still implemented; a code path
that still delivers the removed behavior is reported even when shared.
The summary counts removals separately from covered requirements.

Thanks @ryandemelo, this is a real fix. I pushed two commits to get it ready for merge:

Tests: the template suites pass (732), and all 6 new assertions fail without the fix. On the full suite, the only failures are two sandbox-only tests that fail on main too.

One correctness follow-up is needed before approval.

For a rename-only delta, the current guidance only says not to report the FROM name as missing. It then marks Requirement Implementation Mapping and Scenario Coverage as not applicable, while saying RENAMED entries were settled under Spec Coverage. But Spec Coverage performs no TO-side behavior check. That lets a rename-only change report readiness without verifying that the unchanged requirement behavior is still implemented.

This also falls short of #1959's requested RENAMED semantics: check the new name, while treating absence of the old name as expected.

Please require Spec Coverage to verify the unchanged behavior associated with the TO requirement, using the baseline requirement body/scenarios as evidence where needed and without requiring implementation symbols to be renamed. Mirror that rule in the spec, generated skill and command templates, and add regression coverage for both generated surfaces.

A RENAMED entry only told verify not to report the FROM name as
missing, and a rename-only change marked the correctness checks not
applicable. Nothing checked that the renamed requirement's behavior was
still implemented, so verify could report readiness unchecked.

Spec Coverage now reads the baseline requirement from the main spec
(under the FROM name, or the TO name once synced) and checks that its
behavior is still implemented, without requiring code symbols to be
renamed. A missing behavior is CRITICAL "Renamed requirement not
found"; an unreadable baseline marks the entry not verified. A TO name
that also appears under MODIFIED is still checked there.

Regression tests cover the skill template, the command template, and
the committed skills/ mirror.

@alfred-openspec addressed in 06b3204:

  • RENAMED now checks the TO requirement's behavior. Spec Coverage reads the baseline requirement from the main spec (<planningHome.root>/openspec/specs/<capability-path>/spec.md). It uses the entry under the FROM name, or the TO name only when FROM is absent because the spec is already synced, and checks that its body and scenarios are still implemented. It does not require code symbols to be renamed. If the behavior is missing, that's CRITICAL "Renamed requirement not found: ". If the baseline can't be read, the entry is marked not verified, so an unchecked rename never counts as passing. A TO name that also appears under MODIFIED is still checked there.
  • Rename-only deltas aren't read as empty. Extraction now recognizes FROM:/TO: pairs, since RENAMED entries have no ### Requirement: heading.
  • Mirrored everywhere. The rule is in the skill and command templates, the generated skills/ mirror, and the spec's Renamed requirement scenario.
  • Regression tests run against the skill template, the command template, and the committed SKILL.md, and each surface fails on its own when its text is reverted.

Results: template suites 746/746. The full suite passes, apart from two tests that fail on main in this sandbox too. Lint is clean and validate --specs --strict passes.

Reviewed the follow-up on 06b3204. Rename-only deltas now verify the unchanged requirement behavior from the baseline spec, handle already-synced TO entries, avoid requiring code-symbol renames, and cannot pass when the baseline is unreadable. The generated skill and command plus the committed skill mirror are covered.

Local verification: 75 targeted tests passed, all 36 strict specs passed, and diff checks are clean. The hosted CI and CodeRabbit checks are green.
