Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.02034 | $0.02034 |
| Opus 5 | $0.01017 | $0.01017 |
| Sonnet 5 | $0.00407 | $0.00407 |
| Haiku 4.5 | $0.00203 | $0.00203 |
Grade A, and why
core 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 today.
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.
How it starts
The opening of the file, as written. The whole thing — 298 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
How AI coding agents should operate in this repository.
Important migration note (Turborepo): Nx orchestration has been removed from this repository. Prefer Turbo + package scripts for all build/test/lint workflows.
Scope and Precedence
- Scope: this file applies to the full repository root.
- Precedence: a deeper
AGENTS.mdoverrides this file for its subtree. - This is an agent-operations document, not a contributor tutorial.
Source of Truth (in priority order)
- GitHub Actions workflows in
.github/workflows/*.ymland.github/workflows/*.yaml - Local CI parity runner in
tools/scripts/ci-local.mjs - Root scripts in
package.jsonas wrappers/convenience entrypoints
If prose docs conflict with workflows (for example README.md or CONTRIBUTING.md), follow the workflow commands.
Environment Parity
- Node.js:
24(from.nvmrcand workflow setup) - pnpm:
10.28.0(frompackage.jsonpackageManager) - Package manager: pnpm only
Recommended setup for agents:
corepack enable
pnpm install --frozen-lockfile
Worktree safety rule:
- In git worktree contexts, prefer running Turbo/package scripts directly (
pnpm exec turbo .../pnpm --filter ... run ...).
Worktree Mode (Required in Worktrees)
Use these rules whenever the checkout is a git worktree (typically git rev-parse --git-dir differs from git rev-parse --git-common-dir):
- Setup/install via:
corepack enable
pnpm install --frozen-lockfile
- Run workspace tasks via Turbo/package scripts:
pnpm exec turbo run <task>
pnpm --filter <package-name> run <script>
CI-Aligned Command Matrix
Use these as defaults unless the task explicitly requires something else.
Turbo Task Primer (How to Run Tasks)
- List effective tasks:
pnpm exec turbo run build --dry=json
- Run a task across the workspace:
pnpm exec turbo run <task>
- Run a task for packages only:
pnpm exec turbo run <task> --filter=./packages/**
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.

core AGENTS.md is an instructions file published in the GitHub repository module-federation/core (2,625 stars, last pushed yesterday), licensed MIT. It adds 2,034 tokens to every session, about $0.0102 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
