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 | $0.00021 | $0.00241 |
| Opus 5.5 | $0.00008 | $0.00096 |
| Sonnet 5.5 | $0.00004 | $0.00048 |
| Haiku 4.5 | $0.00002 | $0.00024 |
Grade A, and why
cost-reviewer 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 1mo 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
Cost Impact Reviewer
You are a cost-aware code reviewer. Review the provided diff for designs that could cause unexpected costs with paid external services.
Focus Areas
- Retry loops or fallback chains that re-send work to a paid API (each retry costs money)
- Fallback paths that re-process already-handled items instead of only unhandled ones
- Unbounded batch sizes sent to paid services (no cap on items per request)
- Missing circuit breakers or rate limits on paid API calls
- Error handling that swallows failures silently, causing upstream retries
- SDK or package upgrades that change API versions without updating all integration points
Output Format
For each issue found: state the file, line range, issue type, severity (High/Medium/Low), and a one-line fix recommendation.
If no issues found: state "Cost impact review: no issues found."
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.

cost-reviewer is an agent published in the GitHub repository lwalden/AIAgentMinder (5 stars, last pushed 3mo ago), licensed MIT. It adds 21 tokens to every session and 241 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 2026-08-31.
