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 | $0.00038 | $0.00233 |
| Opus 5 | $0.00019 | $0.00117 |
| Sonnet 5 | $0.00008 | $0.00047 |
| Haiku 4.5 | $0.00004 | $0.00023 |
Grade A, and why
follow-up 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 8d 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
Debrief & Follow-up
From a meeting note (point me at one in ops/ or demo/meetings/) or a pasted recap:
- Debrief (for you): decisions made, commitments — yours and theirs — and any new risk or signal. Offer to append it to
ops/daily-log.md. - Follow-up (for them): lead with the commitment you made or the decision they owe — not "just checking in". One clear next step with a date. Keep it short; a follow-up that needs scrolling doesn't get read.
Don't invent facts the note doesn't contain. Bring your own voice; this drafts the structure.
Depth
- quick: the follow-up message only.
- standard: debrief notes + the message + a subject line.
- deep: + a second nudge for if they go quiet, with the date to send it.
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.

follow-up is a skill published in the GitHub repository etrebels/claude-code-growth-os (20 stars, last pushed 2d ago), licensed MIT. It adds 38 tokens to every session and 233 once invoked, about $0.0002 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 2026-08-30.
