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

send-wecom-msg 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 4d 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 — 136 lines — stays where its author put it; the contents beside it link to each section on GitHub.

<quick_start> Send a message to a user:

wecom send --to-user USERID --message "Hello from the team" --session-id ${CLAUDE_SESSION_ID}

Send a markdown message:

wecom send --to-user USERID --message "**Bold** and `code`" --msg-type markdown --session-id ${CLAUDE_SESSION_ID}

If wecom is not in PATH, use npx wecom or the full path from WECOM_CLI_PATH. </quick_start>

**Build Failed**

Error:

TypeError: Cannot read property 'id' of undefined at processData (src/utils.ts:42)


Please check the logs.

Send with:

wecom send --to-user LiSi --message "**Build Failed**\n\nError:\n\`\`\`\nTypeError: Cannot read property 'id' of undefined\n    at processData (src/utils.ts:42)\n\`\`\`\n\nPlease check the logs." --msg-type markdown --session-id ${CLAUDE_SESSION_ID}

<anti_patterns> Never guess a user ID. If the recipient is unclear, ask: "Who should receive this message? Provide the WeCom user ID."

Report the actual exit code and meaning to the user. </anti_patterns>

<success_criteria>

  • Recipient is specified via --to-user
  • Message is properly quoted for shell execution
  • Markdown is auto-detected when appropriate
  • Session ID is passed via --session-id
  • The actual CLI command is shown before or during execution
  • Results (success or error) are reported clearly </success_criteria>

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.
