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 | $0.00938 | $0.00938 |
| Opus 5.5 | $0.00375 | $0.00375 |
| Sonnet 5.5 | $0.00188 | $0.00188 |
| Haiku 4.5 | $0.00094 | $0.00094 |
Grade B, and why
cc-weixin CLAUDE.md 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 2mo 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
- **Credentials**: Always `chmod 0600` for account files. How it starts
The opening of the file, as written. The whole thing — 95 lines — stays where its author put it; the contents beside it link to each section on GitHub.
cc-weixin Development Guide
Project Overview
WeChat channel plugin for Claude Code and Codex, connecting WeChat via the official iLink Bot API.
Monorepo structure — the plugin source lives under plugins/weixin/.
Code Style
- TypeScript strict mode, ES module syntax (
import/export) - 2-space indentation, LF line endings
- No semicolons omission — always use semicolons
- Prefer
const, useletonly when reassignment is needed - All source files should have a JSDoc module comment at the top
Build & Test
All commands run from plugins/weixin/:
bun install # install dependencies
bun run typecheck # tsc --noEmit
bun test # run all tests
bun test src/media.test.ts # run a single test file
- Prefer running single test files over the full suite during development
- Always run
typecheckafter code changes before committing

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.
