Token cost

What it costs to keep this loaded

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	$0.00469	$0.00469
Sonnet 5	$0.00188	$0.00188
Haiku 4.5	$0.00094	$0.00094

Measured 9d ago against content hash 2f0465791075, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-09, from the pricing page.

Security

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 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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

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, use let only 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 typecheck after code changes before committing

Commit Convention

Follow Conventional Commits:

feat: new feature
fix: bug fix
docs: documentation only
refactor: code restructuring
test: add/modify tests
chore: build/tooling changes

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.
