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 | $0.00929 | $0.00929 |
| Opus 5 | $0.00464 | $0.00464 |
| Sonnet 5 | $0.00186 | $0.00186 |
| Haiku 4.5 | $0.00093 | $0.00093 |
Grade A, and why
chimeralang-mcp CLAUDE.md 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 10d 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.
How it starts
The opening of the file, as written. The whole thing — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ChimeraLang MCP — Project Memory
Token-saving policy (always active)
The canonical routing rules — which chimera_* tool to invoke for each prompt pattern, calling conventions, mode selection, worked examples, and skip conditions — live at:
.claude/skills/chimera/SKILL.md— for Claude Code (auto-loaded as a skill)AGENTS.md— for Codex (same routing matrix at repo root)
Both files are kept in sync via tests/test_skill_integrity.py. Treat the SKILL.md routing matrix as binding for non-trivial tasks; skip chimera tools for prompts < 200 chars with no attachments.
Quick reference
| Situation | Tool |
|---|---|
| Single large doc/code blob | chimera_optimize |
| Long conversation history | chimera_compress |
| Both docs + messages | chimera_fracture |
| Build/test/install logs | chimera_log_compress |
| Stable system blocks for an Anthropic SDK call | chimera_cache_mark |
| End-of-session totals | chimera_session_report |

Hook coverage
The token tools fire automatically via .claude/settings.json:
- SessionStart — emits the policy as
additionalContext. - UserPromptSubmit — auto-compresses prompts > 800 chars.
- PreToolUse — warns on duplicate tool calls (dedup hit) and on
Edit/Write/Bashpayloads > 4000 chars. - PostToolUse — records every non-chimera tool call into the dedup cache and nudges when responses > 2000 chars.
- Stop — emits a session totals summary (tokens saved, dedup hits) when the agent stops responding.
Karpathy Guidelines
Behavioral guidelines to reduce common LLM coding mistakes.
Tradeoff: These guidelines bias toward caution over speed. For trivial tasks, use judgment.
1. Think Before Coding
Don't assume. Don't hide confusion. Surface tradeoffs.
Before implementing:
- State your assumptions explicitly. If uncertain, ask.
- If multiple interpretations exist, present them - don't pick silently.
- If a simpler approach exists, say so. Push back when warranted.
- If something is unclear, stop. Name what's confusing. Ask.
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.

chimeralang-mcp CLAUDE.md is an instructions file published in the GitHub repository fernandogarzaaa/chimeralang-mcp (1 stars, last pushed 3mo ago), licensed MIT. It adds 929 tokens to every session, about $0.0046 per session on Opus 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.
