RHDH spec-driven schema

Give every openspec-* skill one shared place to read the actual RHDH workflow definition, instead of each restating the schema's rules from memory.

What this skill owns

• config.yaml — the project-local schema selection (rhdh-spec-driven), the RHDH context block (split canonical model, journal obligation), and the per-artifact house rules.
• schemas/rhdh-spec-driven/schema.yaml — the authoritative artifact graph: proposal -> {specs, design} -> tasks -> apply, each artifact's instruction text, and the apply block's direct-vs-team mode guidance.
• schemas/rhdh-spec-driven/templates/{proposal,spec,design,tasks}.md — the structural template for each artifact.
• references/artifact-loop.md — the shared mechanics for driving openspec instructions <id> --change <name> --json and turning its response into a written artifact file.
• scripts/install_project_schema.py — copies config.yaml and schemas/rhdh-spec-driven/ into a product repo's openspec/ so the OpenSpec CLI can resolve the schema there.

Install into the product repo (startup / setup)

OpenSpec loads schemas from the project's openspec/, not from this skill directory. Before any openspec new change that should use rhdh-spec-driven, ensure those files are on disk:

python3 scripts/install_project_schema.py

Run that from the product repo (or pass the project root as the first argument). The helper lives next to this skill — resolve scripts/install_project_schema.py relative to this skill's install path, not under the product repo's scripts/. Use --force only when deliberately replacing a customized copy.

Callers (/openspec-new-change, /openspec-ff-change, /openspec-onboard, and /setup-rhdh-skills when seeding a product checkout) check for openspec/config.yaml and openspec/schemas/rhdh-spec-driven/ first and run this install step only when either is missing. Idempotent: existing files are kept unless --force is set. Writing into the product repo is an external write — take it through /mutation-gate when the caller is in a setup or multi-operation plan; a single scaffold turn that already creates openspec/changes/ may include this copy in the same stated set.

Confirm with openspec schemas --json that rhdh-spec-driven is listed, then omit --schema to take the configured default (or pass --schema rhdh-spec-driven explicitly).

Canonical Touchpoints, non-negotiable

Every proposal.md states a Canonical Touchpoints section naming every affected PRD/ADR file under specifications/ and every affected long-lived capability spec under openspec/specs/, or explicitly None, plus the change type: product | architecture | feature-spec | migration | workflow-only | docs-only. design.md and tasks.md carry that same touchpoint set forward — see schema.yaml's per-artifact instruction field for the exact wording each artifact requires. A caller skipping this because "it's a small change" is exactly the case the rule exists for: state None explicitly rather than omitting the section.

Journal obligation

config.yaml's context block states the turn-bookending discipline (log turn.start before work, turn.end after, every prompt, inside an active change) and the apply-phase event set. The mechanics of writing those events belong to openspec-journal, invoked by name — this skill states when the obligation applies; openspec-journal states how to satisfy it.

Completion

Complete when the caller has either installed openspec/config.yaml and openspec/schemas/rhdh-spec-driven/ into the product repo, or read the exact schema/template/context text it needed for the artifact in front of it — rather than guessing at wording. A caller citing this skill without reading schema.yaml's instruction field for that artifact is the failure mode this skill exists to prevent.
