A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

The primary manifest — the file an agent reads to learn what this artifact does.
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 0.8.1) 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.
< 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.> 500 chars), a build/test log, a long message history, or a corpus of multiple docs — go to the Routing matrix below.chimera_session_report so totals are surfaced. The Stop hook does this automatically — only call manually if you want telemetry mid-session.| 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. |
Common mistakes that cause tool errors:
| Tool | Correct call | Wrong call |
|---|---|---|
chimera_log_compress | text="<log content>" | log="..." — param is text, not log |
chimera_optimize | preserve_code=true (JSON bool) | preserve_code="true" (string rejected) |
chimera_cost_track | tokens_saved=265 (integer) | tokens_saved="265" (string rejected) |
chimera_mode | task_description="..." | task_type="..." (unknown args are silently dropped) |
chimera_glyph_translate | verbosity="terse" or "natural" | any other string → silently falls back to "natural" |
chimera_batch | operations=[{"tool": "chimera_optimize", "arguments": {...}}] | flat args — must be an array of {tool, arguments} objects |
| Trigger | First-choice tool | Notes |
|---|---|---|
| Extract claims from text | chimera_claims | Returns atomic claims with hedge/abstention tags. |
| Verify claims against evidence | chimera_verify | method=lexical (default): token-overlap, fast, no deps. method=nli: cross-encoder entailment/contradiction (needs [semantic] extra) — use when you need real contradiction detection. method=llm: Anthropic judge (needs [llm] extra + key), non-deterministic. |
| Multi-perspective analysis | chimera_deliberate | Multiple perspective passes. |
| Confidence-weighted vote across N answers | chimera_quantum_vote | Use when you have multiple candidate responses. |
| Collapse candidates into one consensus | chimera_gate | Lighter than quantum_vote. |
| Hallucination / MCP attack pattern detection | chimera_detect | Pattern-based safety check. |
| Type-check a ChimeraLang program | chimera_typecheck | Static check, no execution. |
| Execute a ChimeraLang program | chimera_run | Returns full execution envelope. |
| Need a Merkle-chain integrity proof of a run | chimera_prove | Heaviest of the run options. |
| Causal graph from claims | chimera_causal | Graph builder; pair with chimera_claims upstream. |
| Calibration error (ECE) from predictions | chimera_metacognize | Needs [{predicted_confidence, was_correct}]. |
| Trigger | Tool sequence |
|---|---|
| Internal reasoning step the user will not read | 1. chimera_glyph_directive(style="strict", task_hint=...) 2. Agent emits CG 3. chimera_glyph_translate(verbosity="natural") to recover English at the boundary. |
| User asks for a system prompt that forces CG | chimera_glyph_directive only — paste the returned directive into the system slot. |
| User pastes CG and wants the English | chimera_glyph_translate(verbosity="natural"); use terse to strip heuristic articles/copulas. |
English (14 tokens): "The user wants to know how to fix the error returned by the function." CG (≈8 tokens): usr wnt kn fix err $rt fn. Decoded English: "User wants know fix error return function."
Measured (0.7.3, 100-sentence benchmark, tiktoken o200k_base):
| Metric | Value |
|---|---|
| Token reduction | −16.0% (Glyph is longer in BPE tokens than English) |
| Character reduction | +19.2% |
| Decode fidelity | 0.806 (lossy by design) |
The hand-crafted glyph approach cannot beat learned BPE on token cost — modern tokenizers already collapse common English to single tokens. Glyph's value is semantic determinism, not compression: deterministic decode (no LLM call needed), sigil-marked entities (@MyService is unambiguously a proper noun), explicit modality tokens (~/?/! for will/might/must). For actual token reduction use chimera_optimize, chimera_fracture, or chimera_cache_mark. See docs/case-studies/chimera-glyph-feature.md for the full benchmark.
Grammar cheat-sheet:
a/an/the) — drop them.is/are/was) — implied by juxtaposition.^ past, ~ future (or standalone ~ = "will"), ? conditional/uncertain ("might"), ! certain ("must"). No suffix = present.i, u, w, t, x (it/this).@ entity (proper noun/identifier preserved verbatim), # concept, $ action.@token.chimera_mode returns four canonical subsets. Pick one early and stick with it for the duration of the task:
| Mode | Tools active | When to use |
|---|---|---|
minimal (6) | csm, budget_lock, gate, confident, memory, policy | Short Q&A, no large payload. Default. |
token (10) | + optimize, compress, fracture, budget, score, cost_estimate, cost_track, dashboard | User has a long doc / log / conversation history. |
agi (19) | + causal, deliberate, metacognize, quantum_vote, plan_goals, world_model, safety_check, ethical_eval, knowledge, claims, verify, provenance_merge, trace, materials | Multi-step reasoning, planning, verification chains. |
full (51) | All | Only when the task genuinely spans every domain (rare). |
Use chimera_mode(task_description="...") for auto-detection — keywords like compress / budget / token / cost steer it to token, while reason / analyze / causal / plan / deliberate steers it to agi.
1. Summarize a large design doc
User: "Here's a 2000-word design doc. Summarize it."
→ chimera_csm
→ chimera_mode(task_description="summarize design doc") # → token mode
→ chimera_optimize(text=<doc>, preserve_code=false) # 60-75% reduction
→ chimera_summarize(text=<compressed_doc>) # deterministic extractive2. Diagnose a failing CI log
User: "Why did my CI fail?" + 500-line log attached
→ chimera_csm
→ chimera_log_compress(text=<log>) # errors verbatim, body abridged
→ answer from compressed log (no additional chimera call needed)3. Multi-perspective analysis
User: "Analyze these 3 competing API designs"
→ chimera_csm
→ chimera_mode(task_description="analyze competing API designs") # → agi mode
→ chimera_deliberate(topic=<question>, perspectives=[<A>,<B>,<C>])
→ chimera_gate(candidates=[<A_analysis>,<B_analysis>,<C_analysis>])4. Claim verification / hallucination check
User: "Is this claim accurate?" + source text
→ chimera_csm
→ chimera_claims(text=<claim_text>) # extract atomic claims
→ chimera_verify(claims=[...], evidence=<source_text>) # method=lexical (default) | nli | llm
→ chimera_detect(text=<claim_text>) # MCP attack / injection check5. AI-to-AI compressed internal reasoning
User: "Reason through this internally then explain your answer"
→ chimera_glyph_directive(style="strict", task_hint=<task>) # get CG system directive
→ [agent emits CG internally]
→ chimera_glyph_translate(glyph_text=<CG_output>, verbosity="natural") # recover EnglishThe skill is enforcing when the agent does these in order:
chimera_csm — call first on every message that has a payload (the description literally says "CALL FIRST on every message").chimera_mode(task_description=<the user's prompt>) — pick the subset.chimera_batch to save round-trips.chimera_score to rank what to keep, chimera_summarize if a compressed answer is acceptable.chimera_session_report — only manually if telemetry is needed mid-session, otherwise the Stop hook handles it.If any of these steps would consume more tokens than they save (e.g. running chimera_optimize on a 100-char prompt), skip that step. The skill is enforcing the intent of using chimeralang-mcp where appropriate, not blanket coverage.
Check chimera_dashboard after a run and respond to these signals:
| Signal | Threshold | Action |
|---|---|---|
avg_pct_saved | < 30% | Inputs may be too short — review whether skip conditions apply; avoid firing chimera on sub-200-char prompts |
avg_pct_saved | > 70% | Healthy — consider chimera_cache_mark on any stable system blocks for additional lossless savings |
Dedup hits (chimera_dedup_lookup) | > 2 in a session | Wrap repeated identical calls in chimera_batch; same inputs should not re-fire |
Session cost (chimera_session_report) | savings > $0.01 | Record for ROI evidence; the dashboard shows per-tool breakdown |
chimera_mode returned minimal | — | Only 6 tools active; if the task grows, re-call chimera_mode with an updated description |
chimera_cost_track errors | — | Fixed in 0.7.2; on < 0.7.2 the entry is persisted despite the error — verify via chimera_dashboard |
< 200 chars and has no attachments.These 24 tools are real but situational. Use them when the primary matrix doesn't cover the need:
| Tool | When to reach for it |
|---|---|
chimera_audit | Audit a ChimeraLang program for policy violations before running it. |
chimera_budget_lock | Hard-cap the token budget for a session so no call can exceed it. |
chimera_confident | Emit a confidence score for a single answer before committing to it. |
chimera_constrain | Apply type constraints to a value (probabilistic type checking at runtime). |
chimera_cost_estimate | Estimate token cost of a planned operation before executing it. |
chimera_cost_track | Log actual tokens saved after a compression step (for dashboard). Note: returns a false UnboundLocalError but DOES persist the entry. |
chimera_dashboard | Retrieve the session cost/savings summary mid-session (Stop hook shows totals automatically). |
chimera_embodied | Model the agent's own physical/environmental context for situated reasoning. |
chimera_ethical_eval | Run a structured ethical evaluation pass on a proposed action or output. |

chimera_social | Model social context (roles, norms, relationship history) for conversational tasks. |
chimera_trace | Emit a structured execution trace for debugging a multi-step chimera pipeline. |

These numbers came from running the actual tools while writing this skill:
chimera_optimize on the project's CLAUDE.md token-policy section: 1463 → 400 chars, 265 tokens saved (72.6%), 4 of 21 sentence units retained, focus terms preserved (chimera_compress, chimera_optimize, conversation, history, ...).chimera_fracture on a mixed payload (650 chars docs + 4-message history, budget 200 tokens): 99 tokens saved, quality gate passed in 3.1 ms.chimera_log_compress on a focused failure log: 24/24 lines kept verbatim because every line carried error/warning/percentage signals — correct behavior for short failure-heavy logs.chimera_glyph_translate round trip on w nd kn how usr wnt fix err in fn. mb aprch ~ wrk. if tst fail ⇒ w ? rt-retry x. → 20 glyph tokens decode to 34 English tokens, modality (maybe, will, might) preserved, zero unrecognized notes.chimera_dashboard after one logged event: 1 request, 265 tokens saved, $0.000795 saved at Sonnet 4.6 pricing, 72.6% avg reduction.Both issues from 0.7.1 were resolved in 0.7.2:
chimera_cost_track returns an UnboundLocalError~~ — fixed in 0.7.2: a local log: list[str] in the chimera_optimize handler shadowed the module-level logger; renamed to passes_log to free the name.chimera_mode accepts task_type but handler reads task_description~~ — not actually a bug: the schema declares task_description, matching the handler. The original 0.7.1 skill note was wrong.Codex does not auto-discover files inside .claude/skills/. The repo-root AGENTS.md (created alongside this file) contains the same routing matrix in Codex's preferred location so a Codex agent walking up from cwd will find it.
If you are inside Codex, treat this file's matrix and decision tree as binding and call the chimeralang-mcp tools through the same routing logic.
