What it costs to keep this loaded
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 | $0.00094 | $0.00519 |
| Opus 5.5 | $0.00038 | $0.00208 |
| Sonnet 5.5 | $0.00019 | $0.00104 |
| Haiku 4.5 | $0.00009 | $0.00052 |
Grade A, and why
review-changes 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 2mo 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.

Your task
Review the changes above. Flag bugs, anti-patterns, missing tests, and any violation of this repo's voice rules. Be terse, be honest, no glazing.
Hard checks (block-on-find)
- No em dashes. Hyphens with spaces, commas, or periods only.
- Never use "ask" as a noun. "A heavy ask" is a rewrite.
- No AWS references. Not in code, not in comments, not in docs.
- No hardcoded secrets. Flag any string that looks like an API key, token, or password.
- No
console.login shipped JS/TS. Test files and demos insegment_*/are fine.
Soft checks (note, don't block)
- Comments explain WHY, not WHAT. Code shows what; comments justify design.
- PowerShell-first for shell scripts. Bash is the fallback.
- Azure-first for cloud examples. Never compare to other clouds.
- Docstrings/JSDoc on every new function or PowerShell script.
- Idempotent re-runs where state mutation is involved.
Report format
## Blockers
- file:line - issue - proposed fix
## Soft findings
- file:line - note
## What's working
- one or two things the diff got right (keep it brief, no glazing)
If the diff is empty, say so and stop. Do not invent findings.
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.
