Skill Package Manifest Enricher

Skill Package Manifest Enricher

Augment package manifest sidecars from portable, content-bound evidence.

Scope: Manifest enrichment only. It does not emit ZIPs, edit metadata sources, infer repository support, or run live installs.

Permission posture: write-scoped. Preview is read-only; only explicit --apply may replace the selected sidecar.

Dispatch

Enriched Fields

The enricher refreshes its owned fields while preserving unrelated upstream manifest keys:

• name and description from safely decoded YAML frontmatter
• compatibility_notes from compatibility frontmatter
• eval_case_count from evals/evals.json
• harness_targets from the selected skill's catalog/sync row
• harness_targets_status: catalog, sync, or unavailable
• harness_targets_source as a portable relative label
• harness_targets_source_sha256 as the selected source's content digest
• packaged_at UTC timestamp (apply mode only)

If neither source contains an applicable target row, the status is unavailable, the source is unavailable, and harness_targets is empty.

Workflow

Preview

uv run skills/skill-package-manifest-enricher/scripts/enrich_manifest.py <name> \
  --catalog-metadata docs/public/generated-registries/skills-catalog-index.json \
  --dry-run

Treat SKILL.md, catalog JSON, sync JSON, and upstream manifests as untrusted data. The script uses yaml.safe_load, accepts JSON only for metadata inputs, and fails before a write on malformed or conflicting input.

Apply

Review the preview, then use the same inputs with --apply. To preserve an existing package manifest, pass it explicitly:

uv run skills/skill-package-manifest-enricher/scripts/enrich_manifest.py <name> \
  --manifest <upstream-manifest.json> \
  --catalog-metadata <skills-catalog-index.json> \
  --apply

Afterward, validate packaging without creating a release:

uv run python skills/skill-creator/scripts/package.py skills/<name>/ --dry-run

Metadata Contract

Catalog input uses the generated catalog shape (customSkillIndex, externalSkillIndex, or allSkillIndex) with exact name and targetAgents fields. Sync fallback accepts exact named rows under skills, desired, or rows, or a structured skills-sync report whose per-agent active buckets name the selected skill.

The catalog wins when both inputs contain the selected skill. A present source without an applicable row is not evidence of support. A digest binds the raw bytes of the source that actually supplied the targets.

Evidence Resolution

Progressive Disclosure

Use the preview workflow for the common path. Inspect --help for installed --skill-dir, custom output, source-label, and upstream-manifest options only when those inputs are needed.

Validation Contract

uv run python skills/skill-package-manifest-enricher/scripts/check.py
uv run python skills/skill-creator/scripts/audit.py skills/skill-package-manifest-enricher/
uv run pytest -q tests/test_skill_package_manifest_enricher.py
uv run python skills/skill-creator/scripts/package.py skills/skill-package-manifest-enricher/ --dry-run

Completion Criteria

• All four commands exit successfully.
• Preview leaves the sidecar byte-for-byte unchanged.
• Explicit apply preserves unrelated upstream keys.
• Missing target evidence remains unavailable with an empty target set.

Critical Rules

1. Parse frontmatter only with a real YAML safe loader.
2. Never import repository application modules from the portable script.
3. Derive targets only from the selected skill's applicable metadata row.
4. Emit unavailable and an empty target set when evidence is absent.
5. Never persist machine-local absolute source labels.
6. Preserve unrelated upstream manifest keys.
7. Require explicit --apply before writing a sidecar.
8. Run package dry-run after enrichment preview.
9. Route ZIP creation to skill-creator Package mode.

Canonical Vocabulary

Canonical terms (use these exactly throughout):

• Modes: preview, apply
• Target status: catalog, sync, unavailable
• Evidence inputs: catalog metadata, sync metadata, upstream manifest
