fix(templates): open generated artifacts with a top-level heading - #1777
Conversation
Generated proposal.md, design.md, spec.md and tasks.md started on a
section header, so every OpenSpec artifact tripped markdownlint MD041
("first line in a file should be a top-level heading") in editors that
run it. The files were also, literally, documents without a title.
Each packaged template now opens with `# Proposal`, `# Design`,
`# Spec Delta` or `# Tasks` followed by a blank line, and
`openspec schema init` scaffolds custom templates the same way. The
schema's own examples and the customization docs match.
Titles are inert to every reader downstream: the parsers anchor on `##`
and `###`, and archive builds a new main spec from the delta's sections,
so the main spec keeps its own generated `# <capability> Specification`
and only that one.
Closes #1138

The Windows runner checks out CRLF, so splitting the template on "\n" left the blank second line as "\r" and the new guards failed there while passing everywhere else.

Review feedback: the guards accepted any top-level heading, so a wrong title would have passed, and the archive check counted `# ` lines only, so a demoted `## Spec Delta` would have slipped through. Assert the exact heading per artifact, the blank line under it in both guards, and that no heading of any level named "Spec Delta" survives archive.

The templates were only half the story. The onboarding walkthrough drafts each artifact in the conversation and then saves what it drafted, so its previews would have written untitled proposal.md, spec.md, design.md and tasks.md whatever the template said. The sync workflow's delta format reference had the same gap, sitting directly beneath a main-spec reference that does carry a title. Both now show the template's title, and `docs/opsx.md` no longer documents a `template` value the CLI never returned. Guards added: - The template guard now enumerates every artifact of every packaged schema from schema.yaml rather than a hardcoded list of four, and the exact-title table must name every artifact the schema declares. - A drift guard reads the titles out of the packaged templates and requires the onboard and sync surfaces to show those same titles, so guidance and template cannot part ways again. - Parser tests pin the claim the fix rests on: a title is inert, and a spec or proposal parses identically with and without one. Regenerated the skill mirrors and parity hashes for the two workflows touched; no other hash moved. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

The implementation looks sound, and the targeted parser, archive, scaffolder, loader, and workflow-parity tests pass locally. One docs blocker remains.
docs-lab/README.md says the live site builds from docs-lab/ and that fixes should land there rather than in the legacy docs/ tree. This PR updates docs/customization.md and docs/opsx.md, but leaves the canonical exact-format page at docs-lab/reference/schemas/spec-driven/index.md stale:
- Its four template examples still begin with
## Why,## Purpose,## Context, and## 1..., omitting the new# Proposal,# Spec Delta,# Design, and# Taskstitles. - The delta instructions still say a new delta “start[s]” / “opens” with
## Purpose, which is no longer true. It is now the first section beneath# Spec Delta.
Please update the canonical docs-lab/ page to match the new generated shape and remove or justify the legacy docs/ edits. Per the repository docs policy, the resulting docs-lab/ changes will also need final review from @TabishB.
The live site builds from docs-lab/, so the exact-format page there is the one readers see. It still showed all four templates opening on a section header and described the delta as starting with `## Purpose`. - reference/schemas/spec-driven/index.md: each template block now matches the shipped template byte for byte, and the quoted spec/tasks instructions match schema.yaml again. - customize/schemas.md: one line telling fork authors to keep the `#` title on the first line. Reverts the edits to docs/customization.md and docs/opsx.md: that tree is no longer published and docs-lab/README.md keeps it as source material only, so editing it would leave two versions of the same fact.

Reviewed head 9faba3272c. The canonical docs-lab/ pages now match the titled artifact templates, the legacy docs edits are removed, the parser and archive behavior remain covered, and all required CI checks pass. This approval is not the final docs approval: @TabishB is still required under the repository policy.
# Conflicts: # test/core/templates/skill-templates-parity.test.ts
The packaged proposal template now opens with `# Proposal`, which `extractTitle` read as the change's title, so `show --json` and `change list --json/--long` titled every templated change "Proposal" instead of its id. Treat that bare heading as untitled. Also re-quote the proposal and specs instructions in the canonical docs-lab schema page after #1700 changed schema.yaml.

Re-reviewed current head bad1176 after the merges from main. The packaged H1 titles, schema-init defaults, change-title fallback, parser/archive behavior, and focused tests remain intact. The upstream edits preserve the onboard/sync title guidance and canonical docs, and the full CI matrix passes with no unresolved review threads. Approving; the docs-lab changes still require final review from @TabishB.
Status
LGTM. All CI checks green on Linux, macOS and Windows. Locally the full suite is green apart from tests that already fail on
origin/mainin this sandbox (workset,version-check,config-profile,artifact-workflow— all spawn real binaries or hit path restrictions). Not merged.Closes #1138
What was wrong
Every artifact OpenSpec generates began on a section header:
Two consequences, one cosmetic and one not:
proposal.md,design.md,spec.mdandtasks.mdin every OpenSpec project. The reporter of Generated MD file documentation should follow MD041/first-line-heading/first-line-h1: First line in a file should be a top-level heading #1138 sees it on all of them.# <capability> Specification, anddocs/getting-started.mdanddocs/concepts.mdhave been showing titled delta specs all along. Change artifacts were the exception.How it was fixed
Each packaged template opens with a title and a blank line:
proposal.md# Proposaldesign.md# Designspecs/<capability-path>/spec.md# Spec Deltatasks.md# Tasks# Spec Deltarather than# Specifications: a delta is not a spec, and the file sitting next to a# <capability> Specificationmain spec should say which one it is.Templates alone would not have finished the job, so this also covers every other place the artifact shape is stated:
openspec schema initscaffolds custom-schema templates the same way, so a forked schema starts lint-clean too.Draft the ... content→Save to the resolvedOutputPath). Its four previews would have written untitled files whatever the template said. They now show the titles.specsandtasksexamples.docs-lab/reference/schemas/spec-driven/index.md: all four template blocks now match the shipped templates byte for byte, and the quotedspecs/tasksinstructions matchschema.yamlagain.docs-lab/customize/schemas.mdgains one line telling fork authors to keep the#title on the first line. The legacydocs/tree is left untouched — the site builds fromdocs-lab/and its README keepsdocs/as source material only.Why this is safe
The title is inert to everything downstream:
##/###(spec-structure.ts,requirement-blocks.ts,extractPurposeSection); a#line matches none of them.MarkdownParserdoes re-shape the tree — with a title,## Purposebecomes a child of the title rather than a root section — butfindSectionrecurses, which is exactly why titled main specs have always parsed.

Guards, each verified to fail before the fix and pass after:
schema.yamland resolves its template, so a new schema or artifact is covered automatically. A second table pins the exact wording per artifact, and a third test requires that table to name every artifact the schema declares.Pre-fix:

End to end against the built CLI,openspec instructions <artifact> --jsonreturns templates opening# Proposal/# Spec Delta/# Design/# Tasks, andvalidate --strict→view→archive --yessucceeds on artifacts written from them.The guards compare on normalized line endings — the Windows runner checks out CRLF, which caught the first version of them.
Suite: 4435 tests. The failures are the same environmental ones a clean
origin/mainclone produces in this sandbox and none of them touch templates. All three CI platforms are green.Notes / nits
SKILL.mdand/opsx-*command files also start on prose. Linting them reports 12 MD041 against ~500 other violations in the same files (line length, emphasis-as-heading, fences), so a title would not make them lint-clean; they are agent instruction payloads rather than documents users lint, and retitling them churns all 12 skill mirrors and their parity hashes. Worth a separate look if anyone actually lints.claude/.MD013(line length — a per-user preference),MD033(the<placeholder>syntax the templates use deliberately) andMD022/MD032from#### Scenario:sitting directly above its- **WHEN**list. That last one is the canonical OpenSpec scenario format used by every existing spec and by archive's own output — changing it is a spec-format decision, not a lint fix. MD041 was uniquely fixable because nothing downstream depends on the first line.onboard,sync-specs, skill and command variants). No other hash moved.default:branch ofcreateDefaultTemplateis unreachable today (schema initonly accepts the four known artifact ids); it was updated anyway so the invariant holds if that set grows.🤖 Generated with Claude Code
