ts-runtime-bun SKILL.md skillA
ts-runtime-bun from fusengine/agents is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add fusengine/agents/ts-runtime-bun@git:20260927.43a351cPins git:20260927.43a351c in mdr.lock. Pin the fingerprint instead.

Use when running TypeScript on Bun — bunfig.toml, bun test, Bun.build/--compile, or Bun workspaces. Not for Node.js runtime setup (ts-runtime-node).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
<objective> This skill covers running TypeScript natively on Bun 1.4.x: configuring bunfig.toml (test coverage thresholds, JUnit reporter, preload), running bun test (Jest-compatible API via bun:test), bundling with Bun.build or producing a single-file executable with bun build --compile --target=, and structuring a Bun workspaces monorepo. It also covers the Bun-vs-Node tradeoff — Bun runs .ts/.tsx natively with no transpile step and does not down-convert modern syntax, but neither its runtime nor bundler perform type checking, so tsc --noEmit stays in CI regardless. Out of scope: Node.js runtime setup (native type stripping, node:test) belongs to ts-runtime-node; tsconfig details belong to ts-config. </objective> # TypeScript on Bun ## Agent Workflow (MANDATORY) Before ANY implementation, spawn 3 agents in parallel, one `Agent` call each with a `name`: 1. **fuse-ai-pilot:explore-codebase** - Inspect `package.json`, `bunfig.toml`, `tsconfig.json` 2. **fuse-ai-pilot:research-expert** - Verify Bun 1.4.x behavior via Context7/Exa 3. **mcp__context7__query-docs** - Check Bun runtime, test, and bundler docs After implementation, run **fuse-ai-pilot:sniper** for validation. …

How to install
mdr add fusengine/agents/ts-runtime-bun@sha256:30b42036f43e2cebThe line at the top of this page pins the label git:20260927.43a351c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
