Regulatory Review Skill
Assess whether the product falls under AI regulation and identify compliance requirements.
Preflight: Read target canvas file(s) before any Write/Edit
Hard rule. Before issuing Write or Edit against any .claude/canvas/*.yml, use the Read tool on that file in this session. Claude Code's Read-before-Write check requires the Read tool specifically — cat/head/grep via Bash do NOT satisfy it.
Edit vs Write — different cost profiles (verified 2026-05-14):
Edit (exact-string replacement): Read with limit: 1 satisfies the check at ~50 tokens. State-tracking is per-file, not per-byte — subsequent Edit calls work anywhere in the file. Use this for partial updates against large canvas files (e.g., purpose.yml at 800+ lines).
Write (full replacement): do a full Read first. Write obliterates the file; you should see what you're about to replace. The limit:1 shortcut is not appropriate here.
ID-bearing entries — scan the ID space before assigning (added 2026-05-15, v0.23.19): When adding a new component, opportunity, solution, or any other ID-bearing entry to a canvas file, run a Bash grep first to confirm the next ID in your prefix sequence is actually free:
grep "^ - id: <prefix>-" .claude/canvas/<file>.yml | sort -u
Replace <prefix> with the canvas's ID prefix (comp for landscape, opp for opportunities, sol for solutions, ht for human-tasks, etc.). Then pick the next free integer. validate_canvas.py has a duplicate-ID check (lines 230-239) that catches the failure on CI, but a duplicate can persist in the working tree for days if CI isn't run between edit and discovery — see roadmap-repo corrections.md 2026-05-15 "Duplicate canvas ID created in landscape.yml" for the worked example.
Original failure mode: anti-pattern #7 instance #5, 2026-05-09 — agent conflated Bash head with the Read tool, lost ~14k tokens to a Write-fail → remedial-full-Read → re-Write loop. The limit:1 discipline (graduated 2026-05-14, v0.23.18) prevents the second-order cost where the agent correctly follows the rule but full-Reads every time. The ID-scan discipline (graduated 2026-05-15, v0.23.19) prevents the related class where the agent reads enough of the file to satisfy the Edit check but not enough to see existing ID assignments — kin to anti-pattern #8 (Stale State Read).
If this skill writes to multiple canvas files, register each one first (limit:1 for Edit-only paths; full Read for Write paths) AND ID-scan any prefix you intend to assign.
See CLAUDE.md Canvas writes — Read before Write for the canonical rule.
When to Use
- At L3 Define->Develop and Develop->Deliver transitions (Regulatory Gate)
- At L4 Develop->Deliver when product_type is
ai_tool
- At L5 Develop->Deliver for any product with user-facing AI features
- When guardrails G-S7 or G-S8 are triggered
Workflow
-
Determine AI presence: Does this product contain AI/ML components?
- If no: document "No AI components -- Regulatory Gate N/A" and stop
- If yes: proceed to classification
-
EU AI Act risk classification (Regulation 2024/1689):
-
Article 50 transparency check (applies from 2 August 2026):
-
Product-type-specific checks:
- ai_tool: Full classification required. Check eval results for bias, safety review for harm potential.
- software: Check if any feature uses AI/ML (recommendations, search, classification). If yes, assess that feature.
- content_*: Check if AI generates or curates content shown to users. If yes, transparency disclosure needed.
- service_offering: Check if AI assists in service delivery decisions. If yes, explainability required.
-
Document findings:
- Update
.claude/canvas/threat-model.yml with regulatory classification
- Update
.claude/canvas/privacy-assessment.yml if data processing is involved
- Log classification decision in
.claude/harness/decision-log.md
-
Determine compliance path:
- Minimal risk: No action required beyond documentation
- Limited risk: Transparency obligations (Article 50)
- High risk: Conformity assessment path must be planned before L4 delivery
- Unacceptable risk: Product cannot proceed in current form
Output Format
## Regulatory Review: [Product Name]
AI Components: [Yes/No]
Risk Classification: [Minimal/Limited/High/Unacceptable]
### Annex III Assessment
| Category | Applicable? | Rationale |
|----------|------------|-----------|
| Biometric | No | ... |
| Critical infra | No | ... |
| ... | ... | ... |
### Transparency Requirements
- AI disclosure needed: [Yes/No]
- Synthetic content marking: [Yes/No]
- Deepfake disclosure: [Yes/No]
### Compliance Path
[What needs to happen before delivery]
### Decision
Regulatory Gate: [Pass/Fail/N-A]
(If Fail, lead the Decision block with a distinct blocker line so it pops — e.g. `BLOCKED: regulatory gate failed — [reason]` — rather than letting the verdict blend into the prose above. Von Restorff; per `harness/design-principles.md`.)
