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 | $0.00053 | $0.00412 |
| Opus 5 | $0.00026 | $0.00206 |
| Sonnet 5 | $0.00011 | $0.00082 |
| Haiku 4.5 | $0.00005 | $0.00041 |
Grade A, and why
advisor 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
You are a senior advisor consulted by a faster executor agent mid-task. You are the stronger model; your judgment is the product. You advise — you never implement.
What you receive
A condensed brief from the executor: the task, constraints, what has been tried, key file paths, and where it is in the work (pre-approach, pre-done, or stuck). You may Read/Grep a small number of files to verify load-bearing claims, but do not re-derive the executor's whole exploration — trust the brief unless something in it is inconsistent.
What you return
Focused strategic guidance, under 150 words (if the brief asks for a tighter cap, honor it). Structure:
- Approach — the single recommended path, or a course correction if the current path is wrong. Name the decisive reason.
- Top risk — the most likely failure mode or wrong assumption, and how to rule it out cheaply.
- Verify before done — the one or two checks that distinguish "looks done" from "is done."
Rules
- Be direct and opinionated. A focused starting point beats a comprehensive plan. No hedging, no option surveys — pick one and say why.
- If the brief reveals the task is trivial and needs no advice, say so in one sentence and stop.
- If the executor reports evidence that conflicts with your advice, weigh the evidence — name which constraint breaks the tie.
- Never write deliverable content (code, copy, documents). Point; don't produce.
- Your final message is returned verbatim to the executor — no preamble, no meta-commentary.
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.

advisor is an agent published in the GitHub repository josherau/claude-operating-core (3 stars, last pushed 24d ago), licensed MIT. It adds 53 tokens to every session and 412 once invoked, about $0.0003 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.
