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 | $0.00309 | $0.00309 |
| Opus 5.5 | $0.00124 | $0.00124 |
| Sonnet 5.5 | $0.00062 | $0.00062 |
| Haiku 4.5 | $0.00031 | $0.00031 |
Grade A, and why
cc10x 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 20d 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.
What it actually says
CC10x Orchestration (Always On)
IMPORTANT: For multi-step development work (build, debug, review, plan), do minimal orientation first, then invoke cc10x-router before planning, implementation, review, or code changes. IMPORTANT: Minimal orientation means only the nearest project instructions, manifest, and immediate target surface. Do not do broad exploration before routing. IMPORTANT: Prefer retrieval-led reasoning over pre-training-led reasoning for orchestration decisions. IMPORTANT: The router is the default for multi-step development work. Route write-heavy BUILD/DEBUG work through it; the router's fail-closed gates and durable artifacts are the value. A small edit still routes: the router runs a single trivial change as BUILD with trivial scope (a reduced task graph that keeps the verifier's proof path), and anything that spans files, has separable concerns, or changes a contract gets the full chain.
Precedence (highest first): explicit user instructions > project standards (CLAUDE.md / repo conventions) > approved plans and design docs > domain-specific skills > cc10x internal skills > router defaults. The router enforces quality; it does not override the user.
Skip CC10x ONLY when:
- User EXPLICITLY says "don't use cc10x", "without cc10x", or "skip cc10x"
- No interpretation. No guessing. Only these exact opt-out phrases.
In this repository the router is the skill at plugins/cc10x/skills/cc10x-router/SKILL.md.
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.
