Status

Ready for design review.

Why

Independent OpenSpec roots in a monorepo cannot share planning context. Package work misses repository-level architecture, while repository-level work cannot see the package specs it may affect.

What was built

Roots can connect through relative references entries in openspec/config.yaml.

  • A package can reference an ancestor and receive its specs, context, and fallback schemas.
  • A repository root can reference a descendant package and read its specs.
  • Changes, spec merges, and archives still write only to the nearest root.

When work affects several roots, create and archive one change in each root.

Design decisions

  • Extend references and leave root selection unchanged. Existing commands keep one clear write target.
  • Keep connections explicit and one hop. OpenSpec does not scan packages, discover siblings, or create recursive graphs.
  • Keep connected roots read-only. A failed command cannot leave several roots partially updated.
  • Inherit configuration only from ancestors. Shared defaults flow down without leaking package-specific settings into repository-level work.

Proof

All CI checks pass. The 153 focused tests include repository-to-package visibility and a real package spec merge and archive that leave the repository root unchanged.

Closes #1729

Summary by CodeRabbit

  • New Features
    • Connect OpenSpec roots in monorepos with explicit, read-only references. Package roots can use ancestor context and schemas; repository roots can inspect referenced package specs.
    • Changes, archives, and other writes remain scoped to the nearest OpenSpec root. Child settings do not flow to parents, and references are not followed recursively.
    • Context and schema listings now identify connected roots and parent-provided schemas.
  • Documentation
    • Updated configuration guidance with reference behavior, path requirements, and inheritance limits.

📝 Walkthrough

Walkthrough

OpenSpec now supports explicit references between co-located roots. References expose specs in both directions, while ancestor context and schemas are available to child roots. Commands continue to use the nearest root for writes.

Changes

Monorepo Root References

Layer / File(s) Summary
Local reference configuration and inheritance
src/core/project-config.ts, test/core/project-config.test.ts, openspec/changes/add-monorepo-parent-references/*, docs-lab/customize/project-config.md, docs-lab/reference/configuration/config-yaml.md, docs-lab/README.md, docs-lab/message-map.md, .changeset/tidy-monorepo-parents.md
Configuration accepts relative paths to strict ancestor or descendant roots containing openspec/. Ancestor context is inherited under the documented precedence and size rules. Documentation and specifications describe which settings remain local.
Local reference indexing and reporting
src/core/references.ts, src/core/working-set.ts, src/commands/context.ts, src/commands/doctor.ts, test/core/references.test.ts, test/core/working-set.test.ts
Local references produce root index entries and working-set members. Context and doctor output identify connected roots. Tests cover ancestor and descendant indexing, invalid paths, and truncated indexes.
Parent schema discovery and precedence
src/core/artifact-graph/resolver.ts, src/commands/schema.ts, test/core/artifact-graph/resolver.test.ts
Schema resolution and listings include ancestor schemas after project schemas. Tests cover parent discovery, child-local precedence, and exclusion of descendant schemas.
Parent-aware instructions and child-root operations
src/commands/workflow/instructions.ts, src/core/artifact-graph/instruction-loader.ts, src/utils/change-metadata.ts, src/utils/change-utils.ts, test/commands/store-references.test.ts
Instruction and change operations read parent-aware configuration. Integration tests verify parent context visibility, descendant spec indexing, and child-root write isolation.

Review details

Systems and components

  • observed — src (service) was modified; 11 changed files map to changed impact.
  • observed — openspec (service) was modified; 5 changed files map to changed impact.
  • observed — test (service) was modified; 5 changed files map to changed impact.
  • observed — docs-lab (service) was modified; 4 changed files map to changed impact.

Before / after behavior

  • observed — Modified behavior in openspec/changes/add-monorepo-parent-references/.openspec.yaml: Adds the schema: spec-driven setting.
  • observed — Modified behavior in src/commands/doctor.ts: Imports isLocalReferenceEntry to distinguish local reference entries in the human-readable report.
  • observed — Modified behavior in src/commands/doctor.ts: Healthy reference labels and identifiers now use local_path for local entries and store_id otherwise; the old output always used store_id.
  • observed — Modified behavior in src/commands/schema.ts: Imports getParentSchemaSources for schema resolution.

test/commands/store-references.test.ts (1)

129-129: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Canonicalize both sides of path identity assertions.

Line 129 canonicalizes child but compares it with the uncanonicalized payload.root.path. The parent-root assertions on Lines 134, 145, and 152 use the same pattern. Canonicalize each actual path before comparison so an alias for the same existing root does not fail an identity assertion.

As per coding guidelines: “When asserting existing filesystem paths as identities, canonicalize both actual and expected paths first.”

Canonicalize both paths in the schema identity assertions.

Compare fs.realpathSync.native() results for both actual and expected paths at Lines 374 and 399. Add an alias-path case so the tests exercise a child root reached through a symlink. As per coding guidelines: “When asserting existing filesystem paths as identities, canonicalize both actual and expected paths first” and “Add an alias-path regression when touching path identity logic.”

Inline comments:
Review comments at @docs-lab/reference/configuration/config-yaml.md:
- Around line 80-81: Separate the two path examples into distinct YAML blocks,
each labeled with the location of its openspec/config.yaml file. Ensure each
block contains only paths relative to that config’s root.

Review comments at @src/core/references.ts:
- Line 470: Update inspectOpenSpecRoot so a referenced root containing
openspec/specs is indexed even when neither config.yaml nor config.yml exists;
do not mark it unusable solely because its config file is missing.

Review comments at @src/core/working-set.ts:
- Line 59: Update isAvailableMember so a connected local_root remains available
when its status includes reference_index_truncated; determine availability from
root resolution and health rather than treating this index warning as unhealthy.
Preserve existing handling of genuinely unavailable or unhealthy roots so the
context command and buildCodeWorkspaceJson continue to include the truncated
root.
