A routing layer for the Chimera language tools, which process prompts and documents for tasks such as claim checking, hallucination detection, and reasoning. It chooses a smaller set of tools based on the request and its size.

Use it with long documents, build or test logs, large conversation histories, multiple documents, verification requests, or tasks that need several Chimera tools.

It avoids sending every request through every available tool, which can reduce unnecessary processing for simple prompts.

Token cost

What it costs to keep this loaded

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	$0.00062	$0.04340
Opus 5.5	$0.00025	$0.01736
Sonnet 5.5	$0.00012	$0.00868
Haiku 4.5	$0.00006	$0.00434

Security

Grade A, and why

chimera 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 24d 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.

Chimera skill — smart routing into chimeralang-mcp

Works for both Claude Code (via this SKILL.md) and Codex (via the sibling AGENTS.md adapter at repo root). Both agents end up running the same routing rules.

The chimeralang-mcp server (currently 0.8.4) exposes 51 tools. Routing all of them through every prompt is wasteful. The goal of this skill is: pick the smallest correct tool subset for the user's actual intent and execute the work through it.

Decision tree (run in order)

Trivial input? If the prompt is < 200 chars and there are no documents/logs/messages attached, skip every chimera tool and answer directly. The token-saving hooks in .claude/settings.json already handle short prompts.
Has structured payload? If the prompt or attached artifact is a document (> 500 chars), a build/test log, a long message history, or a corpus of multiple docs — go to the Routing matrix below.
Reasoning / verification request? If the user is asking for analysis, claim checking, multi-perspective deliberation, or hallucination detection — go to the Reasoning lane.
AI-to-AI reasoning? If the user wants the agent to reason internally (without producing prose for them yet), or wants to compress a system prompt for another LLM — use the Glyph lane.
End-of-task? Always finish with chimera_session_report so totals are surfaced. The Stop hook does this automatically — only call manually if you want telemetry mid-session.

Routing matrix — prompt pattern → chimera tool

Trigger	First-choice tool	Notes
Single doc/code blob > 500 chars	`chimera_optimize`	60–75% reduction typical; preserves fenced code with `preserve_code=true`.
Long conversation history	`chimera_compress`	Proportional truncation to a token budget.
Both docs + history	`chimera_fracture`	Single call with quality gate; prefer this over chaining the two above.
Build / test / install / install log	`chimera_log_compress`	Errors and warnings preserved verbatim, body abridged.
Stable system block reused across SDK calls	`chimera_cache_mark`	Lossless 75–90% via Anthropic prompt cache markers.
Multiple chimera calls in one go	`chimera_batch`	Saves round-trips when the input is fan-out parallel.
Recurring per-turn cost surfacing	`chimera_overhead_audit`	Quantifies "ghost tokens" (system prompt + tool defs).
Inspect repeated tool calls	`chimera_dedup_lookup`	The PostToolUse hook populates the cache.
End-of-session totals	`chimera_session_report`	Bundles cost summary + budget + dedup. Stop hook auto-fires.
LLM-free extractive summary	`chimera_summarize`	Fast and deterministic; no Claude API call.

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.

chimera is a skill published in the GitHub repository fernandogarzaaa/chimeralang-mcp (1 stars, last pushed 6d ago), licensed MIT. It adds 62 tokens to every session and 4,340 once invoked, about $0.0002 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.
