What it does

Tsconfig is an agent skill from EpicenterHQ/epicenter. TypeScript config conventions for this monorepo: the two-base layering, the seven leaf tiers, and the never-redeclare list. Use when adding a package, editing any tsconfig.json, picking a tier for a new app, or debugging module resolution.

Its SKILL.md is about 1.5k 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 Monorepo tooling. It works with TypeScript. The repository describes itself as: Open-source, local-first apps.

When your agent uses it

  • Adding a package
  • Editing any tsconfig.json
  • Picking a tier for a new app
  • Debugging module resolution

Example prompts

  • “/tsconfig”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Scaffold via the monorepo skill's boilerplate.
  2. Pick a tier from the table above; copy that exact shape.
  3. package.json uses exports only, no main/types. Entry point is
  4. bun install at the repo root, then bun typecheck.

What it can do on your machine

Read from SKILL.md and the folder at commit 5b4bb69. 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

    Shell commands in SKILL.md call:

    • bun

    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

Tsconfig loads about 1.5k tokens when it runs. Until then it costs about 62 tokens; SKILL.md has 603 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~62
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 603 words (~1,487 tokens).

“Every package here is source-only .ts: exports point at ./src/*.ts, there is no build step, and consumers (Bun, Vite, Tauri, the Cloudflare Worker) operate on raw .ts. That single fact decides the whole config.”

Can I use Tsconfig in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add EpicenterHQ/epicenter --skill tsconfig -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/tsconfig, .gemini/skills/tsconfig, .github/skills/tsconfig and .opencode/skills/tsconfig in your project.

What does Tsconfig need to run?

Going by SKILL.md and its folder, Tsconfig needs the command-line tools its instructions call (bun).

How many tokens does Tsconfig use?

About 1.5k tokens (SKILL.md is roughly 5.9k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
