sixb AGENTS.md

sixb AGENTS.md is an instructions file for Codex, OpenCode from sixb-ai/sixb. It costs 3,044 tokens per session, scanned A, original, MIT.

A repository guide for sixb, a Bun-and-TypeScript project with a server, command-line tool, React interface, shared components, connectors, and storage providers. It maps the main packages and records the required development tools.

In plain words
What is it for?
Use it when modifying the runtime, HTTP or WebSocket API, React interface, command-line tool, generated client, integrations, or examples.
Why use it?
It helps agents find the right package and use the project’s required Bun and Biome workflow instead of incompatible 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

sixb 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 4d 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.

AGENTS.md

Repo-wide agent instructions for sixb.

Scope

  • This file applies to the whole repository unless a nearer AGENTS.md is added later.
  • Keep one root AGENTS.md for now. Add nested files only when a package genuinely needs different instructions.

Repo Map

  • packages/core: runtime, ontology builders, providers, and validation
  • packages/server: Elysia HTTP/WebSocket API and OpenAPI generation
  • packages/atlas: built-in React UI (the Atlas app); pages live in src/pages/
  • packages/ui: shared React component library used by Atlas
  • packages/client: generated typed client artifacts
  • packages/cli: CLI entrypoint for sixb
  • packages/create-sixb: zero-dependency project scaffolder and template
  • packages/app: custom app integration
  • connectors/, storage/, broker/: integrations and infrastructure providers
  • examples/: runnable sample projects

Toolchain

  • Bun only for package management, scripts, and runtime. Do not use npm, pnpm, yarn, or Vite CLI commands.
  • TypeScript is strict, targets ES2022, uses ESNext modules, and moduleResolution: "bundler".
  • Formatting and linting are enforced with Biome.
  • Prefer rg and rg --files for search.

Core Commands

Repo-wide:

bun install
bun run build
bun run typecheck
bun run test
bun run test:e2e
bun run test:all
bun run check
bun run check:fix
bun run generate:client
bun sixb dev
bun create-sixb my-app

Targeted:

bun --filter @sixb/core build
bun --filter @sixb/core typecheck
bun test packages/core/tests/create-sixb.test.ts
bun test packages/server/tests/

CI runs these as independent parallel jobs (each does bun install --frozen-lockfile first):

  • typecheck: bun run typecheck
  • build: bun run build, then bun run test:publish
  • client: bun run generate:client, then git diff --exit-code
  • test: bun run test:ci
  • lint: bun run check
  • e2e: package-scoped matrix jobs for packages with test:e2e

test:ci is bun test wrapped in scripts/ci-guard.ts, which fails the run at the first 60-second silence and prints the last test file, the process tree, and each thread's kernel wait state. The job's timeout-minutes is only a backstop: a job that dies at its own wall clock reports "cancelled" with the log ending mid-stream, which is indistinguishable from every other cause. The guard exists because a Bun.build() deadlock once cost five 15-minute runs before anyone found the one named failure buried in the log.

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.
