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 -o "<prefix>-[0-9][0-9]*" .claude/canvas/<file>.yml | sort -u -t- -k2 -n | tail -3
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, **matching the zero-padding already used in that file**. The sort is NUMERIC (`-t- -k2 -n`) rather than lexical, and that is not pedantry: a plain `sort -u` orders `ht-1` after `ht-080`, so on a canvas with inconsistent padding it reports the wrong maximum and the next ID collides. Verified on the dogfood repo 2026-08-13, where lexical sort returned `ht-1` as the highest human-task ID against an actual `ht-080`. `grep -o` is also deliberate: it matches IDs wherever they appear, including cross-references and prose, so an ID that was promised somewhere but not yet defined is not handed out twice. `validate_canvas.py` has a per-file duplicate-ID check (it reports `duplicate id '<id>'`) 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; that happened on 2026-05-15, when a duplicate ID was created in `landscape.yml`.
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_PLUGIN_ROOT}/engine/agent-operating-contract.md` *Canvas writes — Read before Write* for the canonical rule.
When to Use
- At an L3's `commit_to_build` and `release` (Regulatory Gate)
- At an L4's `release` when product_type is `ai_tool`
- At an L5's `release` for any product with user-facing AI features
- When guardrails G-S7 or G-S8 are triggered
Workflow
1. **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
2. **EU AI Act risk classification** (Regulation 2024/1689):
- [ ] Check Annex III high-risk categories:
- Biometric identification/categorization
- Critical infrastructure management
- Education and vocational training (access, assessment)
- Employment (recruitment, screening, evaluation)
- Essential services (credit scoring, insurance, social benefits)
- Law enforcement
- Migration and border control
- Justice and democratic processes
- [ ] Classify risk level: Minimal / Limited / High / Unacceptable
3. **Article 50 transparency check** (applies from 2 August 2026):
- [ ] Does the system interact directly with people? -> Must disclose AI nature
- [ ] Does it generate synthetic content? -> Must machine-mark outputs
- [ ] Does it generate deepfakes? -> Must disclose artificial generation
4. **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.
5. **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`
6. **Determine compliance path**:
- Minimal risk: No action required beyond documentation
