TypeScript type-safety guidance. An agent skill from timmo001/system-bridge.

  • Tasks that involve Type safety
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Tasks that involve React components

What it does

Types Enforce TS is an agent skill from timmo001/system-bridge. TypeScript type-safety guidance. Use when editing or reviewing .ts, .tsx, .mts, or .cts files.

Its SKILL.md is about 690 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Type safety and React components. It works with TypeScript. The repository describes itself as: A bridge for your systems. The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Type safety
  • Tasks that involve React components

Example prompts

  • “/types-enforce-ts”

What it can do on your machine

Read from SKILL.md and the folder at commit 504c45d. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Types Enforce TS loads about 689 tokens when it runs. Until then it costs about 30 tokens; SKILL.md has 345 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~30
When it runs · the whole SKILL.md, loaded when a task matches
~689

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

TypeScript Type Safety

Applies only to TypeScript files such as .ts, .tsx, .mts, and .cts.

Use this skill when reviewing or editing TypeScript code:

  • Preserve runtime behavior and public API shape unless the user asked otherwise.
  • Prefer stricter and more precise types over broader types.
  • Reuse or extend existing local types instead of creating duplicate one-off types.
  • Avoid introducing any, unsafe double assertions, or blanket suppressions.
  • Replace any with concrete types or unknown plus narrowing.
  • Prefer narrowing and type guards over non-null assertions and forced casts.
  • Keep inferred types when they are already clear and stable.
  • Do not add explicit return annotations such as : void when the return type is obvious from a local implementation; keep them only for exported APIs, overloads, recursive functions, interface conformance, or genuinely clarifying contracts.
  • Remove unnecessary casts and non-null assertions where safe.
  • Add minimal annotations for function params or returns when clarity or safety improves.
  • Align generics, unions, and nullability with real data flow.
  • For Lit lifecycle methods that receive changed properties (shouldUpdate, willUpdate, update, firstUpdated, updated), prefer changedProperties: PropertyValues<this> for strict typing.
  • For Lit lifecycle methods that need to handle protected or private changed properties, use changedProperties: PropertyValues (without <this>) instead of forcing PropertyValues<this>.
  • Prefer explicit, narrow types.
  • Remove unnecessary intermediate variables and one-off aliases when clarity is maintained.
  • Inline one-time-use values when clarity is maintained.
  • Prefer typing parameters at the signature level when it improves safety or clarity, and rely on inference when types are already clear.
  • Avoid casting later at value access points when signature-level typing or narrowing is clearer.
  • If project generic helpers exist, prefer concrete generic types over ad-hoc casts and loosely typed objects.
  • Prefer top-level annotations and satisfies over type assertions when possible.
  • Do not introduce local aliases only to satisfy TypeScript narrowing (const params = this._params, const data = this._data) if direct guards and property access typecheck cleanly.
  • Keep control flow simple without changing established logic unless explicitly requested.
  • Do not use the non-null assertion operator (!) unless it is strictly required and justified by existing project guidance.
  • Do not add unnecessary comments or abstractions.
