Doc Guardian

When to Use

Use this skill when:

• any skill tries to create, modify, or review a workflow document or review report
• a document is about to change its status, upstream, downstream, or change_history
• progress or CR state needs validation before downstream work continues
• reviewing a derivation to ensure its sources are legally usable as baselines

Do not invoke Doc Guardian on code-only changes or documents outside the workflow chain unless a document compliance concern has been raised.

Inputs

• the document(s) being edited or referenced, including their frontmatter
• progress dashboard at paths.progress
• any related CRs resolved from paths.changes_dir (for example, <from paths.changes_dir>/cr-{nn}.md)
• upstream/downstream documents declared in frontmatter
• derived document drafts that claim to follow from an upstream baseline

Outputs

• blocked edits or derivations when compliance fails, reported with specific violations
• corrected entries in the progress dashboard at paths.progress (with a correction entry appended to paths.progress_history) when actual document state differs from progress
• explicit reminders or issue candidates documenting illegal frozen edits or missing CR approvals

Working Loop

1. Gather the frontmatter, CR references, and document state context for the document set.
2. Validate metadata and legal state flow against the shared protocol references.
3. Check upstream/downstream existence and status legality before allowing derivation or downstream use. Only frozen documents may serve as baselines for downstream derivation.
4. Repair the progress dashboard at paths.progress when it disagrees with frontmatter-derived reality.
5. Block and escalate when frozen edits, missing CR approval, or illegal downstream use is detected.

Document Compliance Rules

• Frontmatter fields and legal state transitions must follow workflow-protocol.
• Only frozen documents may be used as downstream baselines. Documents in draft or active status cannot serve as baselines for downstream derivation.
• Frozen documents may receive only legal small adjustments; larger change paths require an approved CR.
• Validate metadata and evidence against files resolved from workflow-project.yaml, never against literal path strings.
• If the progress dashboard at paths.progress disagrees with actual document state, frontmatter reality wins and progress must be corrected.
• Illegal frozen edits are blocked and escalated to the human immediately.
• Implementation review artifacts include both spec-review-{nn}.md (spec compliance, stage 1) and code-review-{nn}.md (code quality, stage 2). Both follow the standard review frontmatter from workflow-protocol/references/review-report-rules.md. Spec compliance review must exist before code quality review is considered valid.

Completion Checklist

• The relevant frontmatter is valid and legal for the current action.
• Upstream/downstream references exist and allow the requested derivation or edit.
• Any frozen-to-active reopening has a matching approved CR.
• The progress dashboard at paths.progress matches document reality. Any correction also appended to paths.progress_history.
• Any blocked violation has been reported clearly.
