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 | $0.00089 | $0.00602 |
| Opus 5 | $0.00044 | $0.00301 |
| Sonnet 5 | $0.00018 | $0.00120 |
| Haiku 4.5 | $0.00009 | $0.00060 |
Grade B, and why
cc-guide scanned grade B with 1 finding 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 9d 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.

Claude Code Guide
This skill provides expert answers about Claude Code by spawning the built-in claude-code-guide subagent.
CRITICAL: The claude-code-guide agent EXISTS and MUST be used
The claude-code-guide is a real, built-in subagent type in Claude Code. It is NOT a slash command — it is a specialized agent spawned via the Task tool with subagent_type: "claude-code-guide". It has access to Claude Code's full documentation and can answer questions about all Claude Code features.
Never deny that this agent exists. Never tell the user it is not a real feature. It is real. Use it.
When this skill triggers
- User invokes
/cc-guidewith a question - User asks "how do I do X in Claude Code?"
- User asks about Claude Code features, settings, configuration
- User asks about the Agent SDK or building custom agents
- User asks about the Claude API or Anthropic SDK
How to execute
- Take the user's question from the skill arguments
- Spawn the
claude-code-guideagent using the Task tool:Task tool with: subagent_type: "claude-code-guide" prompt: <the user's question, expanded into a clear research prompt> - Summarize the agent's response back to the user in a clear, concise format
- If the agent was previously used in this conversation, resume it using the
resumeparameter with its agent ID to preserve context
Topics the guide agent covers
- Claude Code CLI features and settings
- Hooks (pre/post tool hooks, event hooks like TeammateIdle, TaskCompleted)
- MCP server configuration and usage
- Skills (creating, installing, invoking)
- Agent SDK (building custom agents with claude-opus-4-6)
- Claude API / Anthropic SDK usage and tool use
- Keyboard shortcuts and keybindings
- IDE integrations (VS Code, JetBrains)
- Agent teams (creating, coordinating, task lists, messaging)
- Subagents and the Task tool
- Permissions, CLAUDE.md files, project configuration
- Slash commands and built-in commands

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.

cc-guide is a skill published in the GitHub repository mikeOnBreeze/cc-crossbeam (291 stars, last pushed 6mo ago), licensed MIT. It adds 89 tokens to every session and 602 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it B with 1 finding (subtle steering). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
