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 | $0.01953 | $0.01953 |
| Opus 5 | $0.00977 | $0.00977 |
| Sonnet 5 | $0.00391 | $0.00391 |
| Haiku 4.5 | $0.00195 | $0.00195 |
Grade A, and why
stillpoint 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 5d 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 — 160 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
What this project is
Stillpoint is a small Node.js MCP server that returns short text messages from a fixed library. It has four MCP tools, optional HTTP compatibility endpoints, five content categories, and in-memory session tracking. The entire application logic should fit in a few hundred lines of code. Read docs/stillpoint-architecture.md for the full plan. Read docs/stillpoint-v5.md for the design rationale and content specification.
What to build
The deliverable is a working MCP server with:
- MCP stdio transport as the default runtime (
npm start) reflect,feedback,library_info, andhealthtools- Optional MCP streamable HTTP mode (
npm run start:http) at/stillpoint/mcp - Content loaded from JSON files at startup
- In-memory session state with rate limiting
- Two-channel logging: structured JSON operational logs (stderr in MCP mode, stdout in HTTP mode), SQLite/Postgres database events
- Configuration via environment variables
- Input validation
- Safety tests against content library
That's the whole thing. Nothing else.
How to build it
Plain JavaScript. Not TypeScript. No build step. node server.js runs the server directly.
Express remains only for HTTP compatibility mode. Keep MCP as the primary interface.
better-sqlite3 for local database. pg for Postgres. dotenv for env loading in development. jest for tests. That's the full dependency list. Do not add anything else without an extremely specific reason.
No ORMs. Write SQL strings directly. There are two tables with five columns each. An ORM adds a dependency, an abstraction layer, and a learning curve for contributors, all to avoid writing ~20 lines of SQL.
What NOT to build
This section is more important than the one above.
Do not add TypeScript. No tsconfig.json, no dist/ directory, no type definitions, no compilation step. The project is a few hundred lines. Type safety is nice but not worth the tooling overhead here.
Do not add Docker. No Dockerfile, no docker-compose.yml. Local development is npm install && npm start. Heroku deployment is git push heroku main. Docker solves neither of these.
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.

stillpoint AGENTS.md is an instructions file published in the GitHub repository sterlingcrispin/stillpoint (10 stars, last pushed 6mo ago), licensed MIT. It adds 1,953 tokens to every session, about $0.0098 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.
