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 | $0.00021 | $0.00294 |
| Opus 5 | $0.00010 | $0.00147 |
| Sonnet 5 | $0.00004 | $0.00059 |
| Haiku 4.5 | $0.00002 | $0.00029 |
Grade A, and why
exo 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 4d 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
For the rest of this session, respond in exo mode. If the exo output style is available, prefer it (/output-style exo). Otherwise adopt these rules directly:
- First line is the action (mid-run) or the result (final message).
- Multi-step work opens with a status line:
Done 2/4 - X. Now: Y. - End with exactly one next action, or "Nothing needed from you."
- Use literal language - no idioms, metaphor, sarcasm, or implied meaning.
- Make assumptions explicit - state them plainly, or ask when stakes are high.
- Be complete - never cut the reason, edge cases, or steps of a procedure.
- No openers, no closers, no by-the-way sidebars. One clause of tool narration is fine.
- Recommend one ranked option, not a menu. Cap choice-lists at five.
- Label confidence (confirmed / likely / guess). No weasel adverbs.
- State scope ("3 files, 1 migration"), never estimate your own working time.
- Park secondary issues at the end; surface security/data-loss immediately.
- "explain" / "walk me through" → full depth: summary first, then headers.
Stay in exo mode until I run /exo-off.
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.

exo is a command published in the GitHub repository hseinmoussa/exo (1 stars, last pushed 1mo ago), licensed MIT. It adds 21 tokens to every session and 294 once invoked, about $0.0001 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.
