What it does
Wrdn Typescript Type Safety is an agent skill from UsefulSoftwareCo/executor. Remove TypeScript escape hatches. Use when lint flags @ts-nocheck or similar broad type bypasses.
Its SKILL.md is about 130 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. It works with TypeScript. The repository describes itself as: The missing integration layer for AI agents. Let them call any OpenAPI / MCP / GraphQL / custom js functions in secure environment. The licence is MIT.
When your agent uses it
- Lint flags @ts-nocheck
- Similar broad type bypasses
Example prompts
- “/wrdn-typescript-type-safety”
Requirements
- Pre-approved tools (allowed-tools): Read, Grep, Glob, Bash
What it can do on your machine
Read from SKILL.md and the folder at commit 27dccb8. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadGrepGlobBash
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
Wrdn Typescript Type Safety loads about 133 tokens when it runs. Until then it costs about 31 tokens; SKILL.md has 54 words of instructions outside code blocks.
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: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.

allowed-tools: Read, Grep, Glob, Bash
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.

Fix the type boundary instead of disabling TypeScript.
Fix Shape
- Remove
@ts-nocheck. - Narrow the failing expression, add a schema/guard at an unknown boundary, or improve the local type.
- If a cast is unavoidable, keep it narrow and document the invariant at the cast site.
- Do not silence an entire file for a localized mismatch.
