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 | $0.01609 | $0.01609 |
| Opus 5.5 | $0.00644 | $0.00644 |
| Sonnet 5.5 | $0.00322 | $0.00322 |
| Haiku 4.5 | $0.00161 | $0.00161 |
Grade B, and why
agent-notifier CLAUDE.md scanned grade B with 1 finding 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
**Adapter contract:** `export function classify(payload: unknown): Event | null` — never throws, returns `null` for unmapped events. **Single notify chokepoint:** all dispatch flows through `core/notify.ts`; idle-gating, How it starts
The opening of the file, as written. The whole thing — 95 lines — stays where its author put it; the contents beside it link to each section on GitHub.
agent-notifier — CLAUDE.md
Cross-platform desktop notifier for AI coding CLIs. Hooks into Claude Code, Codex, Gemini CLI, and OpenCode and pings the user on macOS or Windows when a session needs attention — permission, idle 60s, turn done. One install, every agent, every machine.
Working Rules
- Think first — state assumptions, surface tradeoffs, ask when unclear.
- Minimum code — no features beyond the ask, no speculative flexibility, no error handling for impossible cases.
- Surgical edits — every changed line traces to the request; flag pre-existing dead code, don't delete it.
- Goal-driven — restate the task as a verifiable success criterion before coding.
- Cross-platform always — every change works on macOS and Windows. If a path is OS-specific, the other OS gets an equivalent test or a documented manual smoke step.

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.

agent-notifier CLAUDE.md is an instructions file published in the GitHub repository JohnPremKumar/agent-notifier (1 stars, last pushed 6mo ago), licensed MIT. It adds 1,609 tokens to every session, about $0.0064 per session on Opus 5.5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
