What it does

System Bridge Connector Typescript is an agent skill from timmo001/system-bridge. Work on the System Bridge TypeScript connector (@timmo001/effect-system-bridge) in connector/typescript. Use when changing its Effect services, schemas, errors, generated module schemas, tests or packaging, or when running its lint, type check, test or build tasks.

Its SKILL.md is about 780 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 Backend & APIs, covering Linting and formatting. 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

  • Changing its Effect services
  • Generated module schemas
  • Running its lint

Example prompts

  • “/system-bridge-connector-typescript”

What it can do on your machine

Read from SKILL.md and the folder at commit 94a7adc. 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:

    • mise
    • go
    • 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

System Bridge Connector Typescript loads about 779 tokens when it runs. Until then it costs about 75 tokens; SKILL.md has 342 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~75
When it runs · the whole SKILL.md, loaded when a task matches
~779

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.

description
Work on the System Bridge TypeScript connector (@timmo001/effect-system-bridge) in connector/typescript. Use when changing its Effect services, schemas, errors, generated module schemas, tests or packaging, or when running its lint, type check, test or build tasks.

System Bridge TypeScript Connector

The @timmo001/effect-system-bridge package in connector/typescript/ is an Effect v4 connector for the backend's HTTP and WebSocket APIs. The web client uses it through the Bun workspace (workspace:*). Load the effect skill alongside this one.

Layout

  • src/http.ts: SystemBridgeApi (HttpApi) and the SystemBridgeHttp service built on HttpApiClient
  • src/websocket.ts: the SystemBridgeWebSocket service on effect/socket. It matches replies to requests by id, waits for the expected response type and publishes DATA_UPDATE messages to the updates stream
  • src/protocol.ts: event and response types, request and reply payload schemas, settings
  • src/errors.ts: tagged errors
  • src/generated/modules.ts: generated module schemas. Never edit by hand

Generated schemas

mise run generate:schemas regenerates src/generated/modules.ts from the Go types in types/, using tools/generate-schemas. Run it after changing those types, then go test ./tools/generate-schemas/. The connector CI fails when the committed file is out of date.

Tasks

All tasks live in the root mise.toml and run from the repository root. They depend on install:js, which installs the root Bun workspace.

  • All checks: mise run lint:connector:typescript ::: typecheck:connector:typescript ::: test:connector:typescript
  • Lint: mise run lint:connector:typescript (Oxlint with @timmo001/oxlint-rules recommended-effect, type-aware, and a Prettier check)
  • Type check: mise run typecheck:connector:typescript (source, then tests with tsconfig.test.json)
  • Format: mise run format:connector:typescript
  • Test: mise run test:connector:typescript (bun test)
  • Build: mise run build:connector:typescript

mise run check and mise run lint:all include the connector.

Code style

  • Lint must pass with no warnings. Fix findings rather than disabling rules
  • Prefer Effect's own modules (HttpApiClient, Socket, Schema, PubSub) over hand-written clients or parsing
  • Decode every backend payload through a Schema and map failures to the connector's tagged errors
  • Keep tokens in Redacted
  • Tests use bun:test with fake backends from Bun.serve. Fixtures in test/fixtures/ are trimmed, sanitised module data; never commit captured data from a real machine as-is

Releases

  • The connector is released with System Bridge. Each stable GitHub release publishes it to npm and JSR from build-and-package-application.yml.
  • version in package.json and jsr.json stays 0.0.0. CI sets it from the release tag, so don't bump it by hand.
  • LICENSE lives at the repository root. The build script copies it into connector/typescript/, and that copy is gitignored.
