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 | $0.05977 | $0.05977 |
| Opus 5 | $0.02988 | $0.02988 |
| Sonnet 5 | $0.01195 | $0.01195 |
| Haiku 4.5 | $0.00598 | $0.00598 |
Grade C, and why
builders-stack AGENTS.md scanned grade C with 2 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 228 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md — the primer for coding agents
Cross-tool guide for any AI coding agent working in this repo (Claude Code, Cursor, Codex, Copilot, Windsurf, …).
Codex, Cursor, and Copilot read a repo-root AGENTS.md by convention — this file is the source of truth. Claude Code also reads CLAUDE.md; Cursor reads .cursor/rules.md. Both are short mirrors that point back here.
Read this before writing code. It tells you where everything lives so you don't reinvent what already exists.
RULE ZERO — WORKTREES ARE TEMPORARY AND SHARE DEPENDENCIES
Parallel work must use ops/dev/worktree.sh <branch>. Do not run raw
git worktree add, copy node_modules, or symlink one checkout's complete
node_modules into another checkout. The wrapper uses Bun 1.3.14's isolated
global virtual store, so immutable packages are installed once and each
worktree gets its own small tree of links. A whole-directory symlink is unsafe
when branches change dependencies or an install mutates the directory.
Every agent that creates a worktree owns its cleanup:
- After the PR is merged or the task is abandoned, leave that checkout and run
ops/dev/worktree.sh --rm <branch>from the main checkout. - Run
ops/dev/worktree.sh --gcbefore creating more worktrees when old work is finished. The wrapper caps managed worktrees at eight; do not bypass the cap. - Never force removal. The wrapper refuses to remove a dirty worktree, a
worktree with a live process, or a branch whose patch is not in
origin/main. Preserve and finish that work instead. - Keep
package.json,.tool-versions, CI's Bun version, andbunfig.tomlin sync. Do not override the isolated linker or disableglobalStore.
No cleanup request overrides the dirty, active, or unmerged-work checks.
1. The mental model — the buckets
This is a bun-workspace monorepo wrapped by Nx (task graph + enforced boundaries + generators). Every package has a role defined by one question: is it served, and to whom?
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.

builders-stack AGENTS.md is an instructions file published in the GitHub repository lonormaly/builders-stack (41 stars, last pushed 16d ago), licensed MIT. It adds 5,977 tokens to every session, about $0.0299 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
