A project instruction file for the `opencode-ccs-sync` repository. It records commands for building, testing, linting, and formatting, plus TypeScript and import conventions.

In plain words
What is it for?
Use it when working on that repository, particularly for running Bun tests, formatting with Prettier, linting with ESLint, or editing TypeScript code.
Why use it?
It gives an agent the repository's exact development rules so generated changes match the project's expected style and can be checked with its usual commands.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

opencode-ccs-sync AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

89% identical to open-conclave AGENTS.md — 4 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Build & Test Commands

  • Build: mise run build or bun build ./src/index.ts --outdir dist --target bun
  • Test: mise run test or bun test
  • Single Test: bun test BackgroundTask.test.ts (use file glob pattern)
  • Watch Mode: bun test --watch
  • Lint: mise run lint (eslint)
  • Fix Lint: mise run lint:fix (eslint --fix)
  • Format: mise run format (prettier)

Code Style Guidelines

Imports & Module System

  • Use ES6 import/export syntax (module: "ESNext", type: "module")
  • Group imports: external libraries first, then internal modules
  • Use explicit file extensions (.ts) for internal imports

Formatting (Prettier)

  • Single quotes (singleQuote: true)
  • Line width: 100 characters
  • Tab width: 2 spaces
  • Trailing commas: ES5 (no trailing commas in function parameters)
  • Semicolons: enabled

TypeScript & Naming

  • NeverNesters: avoid deeply nested structures. Always exit early.
  • Strict mode: enforced ("strict": true)
  • Classes: PascalCase (e.g., BackgroundTask, BackgroundTaskManager)
  • Methods/properties: camelCase
  • Status strings: use union types (e.g., 'pending' | 'running' | 'completed' | 'failed' | 'cancelled')
  • Explicit types: prefer explicit type annotations over inference
  • Return types: optional (not required but recommended for public methods)

Error Handling

  • Check error type before accessing error properties: error instanceof Error ? error.toString() : String(error)
  • Log errors with [ERROR] prefix for consistency
  • Always provide error context when recording output

Linting Rules

  • @typescript-eslint/no-explicit-any: warn (avoid any type)
  • no-console: error (minimize console logs)
  • prettier/prettier: error (formatting violations are errors)

Testing

  • Framework: vitest with describe & it blocks
  • Style: Descriptive nested test cases with clear expectations
  • Assertion library: expect() (vitest)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
