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 | $0.02217 | $0.02217 |
| Opus 5.5 | $0.00887 | $0.00887 |
| Sonnet 5.5 | $0.00443 | $0.00443 |
| Haiku 4.5 | $0.00222 | $0.00222 |
Grade D, and why
claude-code-reflector CLAUDE.md scanned grade D with 2 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.
Reaches for credential fileshighPrivilege escalation
SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.
- `AWS_ACCESS_KEY_ID` / `AWS_SECRET_ACCESS_KEY` - or use `~/.aws/credentials` Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

Claude Code Reflector
Analyzes Claude Code sessions to detect missing CLAUDE.md rules, unused skills, and skill corrections. Uses a two-tier architecture: Haiku for broad candidate detection, Sonnet for deep verification with full conversation context.
Sibling project to ~/private/code-claude-auto-learn (which captures what the user explicitly teaches). This project detects what's missing or broken that the user may not have noticed.

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.

claude-code-reflector CLAUDE.md is an instructions file published in the GitHub repository omril321/claude-code-reflector (2 stars, last pushed 7mo ago), licensed MIT. It adds 2,217 tokens to every session, about $0.0089 per session on Opus 5.5. A static security scan graded it D with 2 findings (reaches for credential files, reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
