AI Commenting

AI Commenting Skill

Create and maintain AI-native annotations so coding agents can understand intent, risk, and constraints quickly and safely.

When to Use

Use this skill when:

• introducing a new module with high coupling
• touching auth/payment/state consistency paths
• preparing codebase context for multi-agent implementation
• reducing repeated prompt context for long tasks

Annotation Format

Canonical format:

/*@ai:key=value|key=value|key=value*/

Rules:

• ASCII keys/values only
• | as field separator
• no spaces around =
• one annotation per scope (file or risky block)

Field Schema

Core file-level fields:

• risk=1-5
• core=<domain>
• deps=<A,B,C>
• intent=<why>
• test=<unit|integration|e2e|contract>

Extended fields:

• chain=<A->B->C>
• auth=<none|required|strict>
• security=<none|pii|payment|secret>
• invariant=<must_hold>
• sidefx=<db,cache,queue,event>
• perf=<budget>
• rollback=<strategy>

Risk Rubric

• risk=1: isolated local logic
• risk=2: low coupling, easy rollback
• risk=3: moderate coupling or external dependency
• risk=4: critical cross-module path
• risk=5: security/payment/core-state high blast radius

Escalate by +1 if auth/session/payment/PII/secrets are touched.

Placement Strategy

1. File header annotation for critical modules
2. Block-level annotation only for risky functions

Keep annotations high-signal. Avoid tagging trivial code.

Example

/*@ai:risk=5|core=UserCRUD|intent=protect_user_consistency|deps=UserModel,AuthService,AuditService*/
/*@ai:chain=Auth->User->Permission->Audit|auth=strict|sidefx=db,event|test=integration|rollback=feature_flag*/
class UserManager {
  /*@ai:risk=4|invariant=user_id_unique|security=pii|perf=p95<200ms*/
  async deleteUser(userId: string) {
    // ...
  }
}

Workflow

1. Discover high-risk boundaries
2. Add file-level core tags
3. Add targeted block-level tags
4. Validate syntax and consistency
5. Ensure risk>=4 has explicit test and rollback

Quality Gates

• all risk>=4 files include file-level annotation
• security!=none implies auth!=none
• no contradictory tags per scope
• prefer 1 annotation per 60-120 LOC

Parsing Helpers

const aiTagPattern = /\/\*@ai:([^*]+)\*\//g;
const fieldPattern = /(\w+)=([^|*]+)/g;

Output

Return a concise markdown report:

• Result summary
• Files changed
• Validation evidence
• Risks / next actions
