weixin-access is a skill for Claude Code from qufei1993/cc-weixin. It costs 17 tokens per session (367 once invoked), scanned A, original, MIT.

An access-control tool for a coding assistant that receives messages through WeChat. It uses pairing codes and an allowlist, which is a list of approved user IDs.

What is it for?
Confirming six-digit pairing codes, adding or removing user IDs, changing the access policy, and viewing the current access settings.

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.

Security

Grade A, and why

weixin-access 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 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.

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

WeChat Access Control

Manage who can send messages to your AI coding assistant via WeChat.

Instructions

Parse the command argument and perform the appropriate action:

pair <code>

Confirm a 6-digit pairing code. Call confirmPairing(code) from ./src/pairing.js.

  • If valid: display the confirmed user ID and confirm they've been added to the allowlist.
  • If invalid/expired: display an error.

allow <userId>

Manually add a user ID to the allowlist:

  1. Load access config with loadAccessConfig()
  2. Add the userId to allowFrom if not already present
  3. Save with saveAccessConfig()
  4. Confirm the user was added

remove <userId>

Remove a user ID from the allowlist:

  1. Load access config
  2. Remove the userId from allowFrom
  3. Save the config
  4. Confirm removal

policy <mode>

Set the access policy. Mode must be one of: pairing, allowlist, disabled.

  • pairing: New users get a pairing code, must be confirmed (default)
  • allowlist: Only pre-approved users can message (no new pairing codes)
  • disabled: Anyone can message (not recommended)

status

Display current access configuration:

  • Current policy
  • Number of allowed users
  • List of allowed user IDs

Import functions from ./src/pairing.js and ./src/accounts.js.

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.
