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 5.1 | $0.00017 | $0.00150 |
| Opus 5.5 | $0.00007 | $0.00060 |
| Sonnet 5.5 | $0.00003 | $0.00030 |
| Haiku 4.5 | $0.00002 | $0.00015 |
Grade A, and why
how-am-i-doing 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 yesterday.
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
Give me an honest read of how I am doing today.
Call the marrow daily_brief tool first. If anything in it is flagged, call baselines for that metric to see the trend. Then answer in a few short lines: what is normal for me today, what is above or below my normal, how food and water stand against my targets, and one thing worth doing with the rest of the day. Use the brief's own phrases (normal for you, above your normal) rather than population ranges. Do not diagnose or alarm. If a stream is stale or missing, say so plainly instead of guessing.
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.

how-am-i-doing is a command published in the GitHub repository skeletonarmytech/marrow-mcp (3 stars, last pushed yesterday), licensed MIT. It adds 17 tokens to every session and 150 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-10-22.
