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 | $0.00582 | $0.00582 |
| Opus 5 | $0.00291 | $0.00291 |
| Sonnet 5 | $0.00116 | $0.00116 |
| Haiku 4.5 | $0.00058 | $0.00058 |
Grade A, and why
source-agents 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 3d 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.
How it starts
The opening of the file, as written. The whole thing — 46 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Repository Guidelines
Project Structure & Modules
- Source lives in
src/with ESM TypeScript.- CLI entry:
src/cli.tsx→ built todist/cli.js. - UI:
src/components/(Ink + React). - Logic:
src/services/(scanner, analyzer, executor). - Helpers:
src/utils/, shared types insrc/types/.
- CLI entry:
- Build output in
dist/(committed artifacts are not expected).
Build, Test, and Dev
- Install:
bun install - Dev TUI:
bun run dev --root ~/projects(use--auto,--dry-run,--excludeas needed). - Type‑check:
bun run type-check - Build:
bun run build(emits ESM todist/). - Start built CLI:
node dist/cli.js --help - CI runs type‑check, build, and a smoke CLI help check.
Coding Style & Naming
- TypeScript strict, ESM imports, 2‑space indent.
- Components: PascalCase files (
ResultsTable.tsx,ActionMenu.tsx). - Services/Utils/Types: lowercase filenames (
scanner.ts,paths.ts,index.ts). - Use camelCase for variables/functions, UPPER_SNAKE_CASE for constants, named exports preferred.
- Keep functions small and pure in
services/; UI logic stays incomponents/.
Testing Guidelines
- No formal test suite yet; contributions welcome.
- Prefer Vitest for unit tests; place tests under
src/**/__tests__with*.test.ts. - Target high‑value coverage for
services/(scanner/analyzer/executor). Aim for 80%+ on touched files. - Add lightweight CLI smoke tests if feasible.
Commit & Pull Requests
- Use Conventional Commits:
feat:,fix:,docs:,refactor:,chore:. - Scope clearly and write imperative, present‑tense summaries (≤72 chars).
- PRs should include: summary, motivation, screenshots or sample CLI output, steps to verify, and linked issues.
- Keep diffs focused; update README or this file if behavior changes.
Security & Configuration
- Requires Node 18+ and Bun 1.1+. ESM only.
- Use
--dry-runfor potentially destructive actions; limit scans with--root. - Default excludes:
node_modules,.git,dist, common build caches. Add extras via--exclude.
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.

source-agents AGENTS.md is an instructions file published in the GitHub repository iannuttall/source-agents (124 stars, last pushed 10mo ago), licensed MIT. It adds 582 tokens to every session, about $0.0029 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 2026-08-30.
