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 | $0.00185 | $0.00185 |
| Opus 5 | $0.00093 | $0.00093 |
| Sonnet 5 | $0.00037 | $0.00037 |
| Haiku 4.5 | $0.00018 | $0.00018 |
Grade C, and why
agent-skills CLAUDE.md scanned grade C 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 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.

@AGENTS.md
Claude Code
- Prefer Zephex MCP for their codebase over blind Grep/Read when a tool fits.
- After failed tool calls, use
keep_thinkingwithlastActionsbefore repeating the same approach. - Call
check_packagebeforenpm install,pip install, orcargo add. - After substantive edits, prefer
check_test(taskrun) when the user cares about green tests. - Terminal Mode 2 only if CLI is installed and the user wants shell output:
cdtheir project first, thenzephex overview/structure --agent/architecture/deep --json/find/test/check test failures. - Install CLI:
curl -fsSL https://zephex.dev/cli/install.sh | bash(same as/install.sh).
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-skills CLAUDE.md is an instructions file published in the GitHub repository zephexMCP/agent-skills (5 stars, last pushed 26d ago), licensed MIT. It adds 185 tokens to every session, about $0.0009 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
