Principles

Enable strict mode — no implicit any, strict null checks
Prefer discriminated unions over type assertions
Use
```
unknown
```
over
```
any
```
— narrow with type guards

Rules

See rules index for detailed patterns.

Examples

Positive Trigger

User: "Replace unsafe any usage with discriminated unions in this module."

Expected behavior: Use

lang-typescript

guidance, follow its workflow, and return actionable output.

Non-Trigger

User: "Design REST route naming conventions for a new backend."

Expected behavior: Do not prioritize

lang-typescript

; choose a more relevant skill or proceed without it.

Troubleshooting

Skill Does Not Trigger

Error: The skill is not selected when expected.
Cause: Request wording does not clearly match the description trigger conditions.
Solution: Rephrase with explicit domain/task keywords from the description and retry.

Guidance Conflicts With Another Skill

Error: Instructions from multiple skills conflict in one task.
Cause: Overlapping scope across loaded skills.
Solution: State which skill is authoritative for the current step and apply that workflow first.

Output Is Too Generic

Error: Result lacks concrete, actionable detail.
Cause: Task input omitted context, constraints, or target format.
Solution: Add specific constraints (environment, scope, format, success criteria) and rerun.

Workflow

Identify whether the request clearly matches
```
lang-typescript
```
scope and triggers.
Apply the skill rules and referenced guidance to produce a concrete result.
Validate output quality against constraints; if gaps remain, refine once with explicit assumptions.
