Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00516 | $0.00516 |
| Opus 5 | $0.00258 | $0.00258 |
| Sonnet 5 | $0.00103 | $0.00103 |
| Haiku 4.5 | $0.00052 | $0.00052 |
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 3d 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 — 39 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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 single trivial one-line edit need not pay full routing, but anything that spans files, has separable concerns, or changes a contract should route.
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.

Complementary Skills (Work Together with CC10x)
Add to ~/.claude/CLAUDE.md:
## Complementary Skills (Work Together with CC10x)
**Skills are additive, not exclusive.** CC10x provides orchestration. Domain skills provide expertise. Both work together.
**GATE:** Before writing code, check if task matches a skill below. If match, invoke it via `Skill(skill="...")`.
| When task involves... | Invoke |
|-----------------------|--------|
| MongoDB, schema, queries, indexes | `mongodb-agent-skills:mongodb-schema-design` or `mongodb-query-optimizer` |
| React, Next.js, frontend, UI | `react-best-practices` |
[Skills Index]
|mongodb-agent-skills:{mongodb-schema-design/SKILL.md,mongodb-query-optimizer/SKILL.md}
|vercel-agent-skills:{react-best-practices/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.

cc10x CLAUDE.md is an instructions file published in the GitHub repository romiluz13/cc10x (164 stars, last pushed 1mo ago), licensed MIT. It adds 516 tokens to every session, about $0.0026 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 2026-08-30.
