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 | $0.00000 | $0.00221 |
| Opus 5 | $0.00000 | $0.00111 |
| Sonnet 5 | $0.00000 | $0.00044 |
| Haiku 4.5 | $0.00000 | $0.00022 |
Grade A, and why
keep-readme-updated 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.
What it actually says
keep-readme-updated:
- When adding, removing, or renaming an
@mcp.tool()function inmcp-server/server.py, update both tool tables:- The "Available MCP Tools" section in the root
README.md - The "MCP Tools" section in
AGENTS.md
- The "Available MCP Tools" section in the root
- Each tool should have one row with its function name and a short description derived from the first line of its docstring.
- Tools are grouped into "Workspace Intelligence" (read-only queries) and "Task Authoring / Tool Builder" (script lifecycle).
- If a new tool doesn't fit either group, add a new section in both files.
- Keep the "How It Works" workflow diagram in
README.mdcurrent if the workflow changes.
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.

keep-readme-updated is a cursor rule published in the GitHub repository runwhen-contrib/runwhen-platform-mcp (1 stars, last pushed 20d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 221 tokens. 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.
