SkillSpector: 2 findings, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
    Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

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

feishu-doc 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 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.

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

Feishu Doc

Read, write, and manage Feishu/Lark documents (Docs) using the Feishu Open API.

  • Base URL: https://open.feishu.cn/open-apis
  • Auth: obtain a tenant access token via POST /auth/v3/tenant_access_token/internal with {"app_id": ..., "app_secret": ...}. Cache the token (valid 2 hours) in memory.
  • List documents: GET /docx/v1/documents — returns document list for the current user.
  • Get document content: GET /docx/v1/documents/{document_id}/raw_content — returns Markdown-like plain text.
  • Get blocks: GET /docx/v1/documents/{document_id}/blocks — returns structured block tree.
  • Create a document: POST /docx/v1/documents with {"folder_token": "...", "title": "..."}.
  • Update a block: PATCH /docx/v1/documents/{document_id}/blocks/{block_id} with block content.
  • Append content: use POST /docx/v1/documents/{document_id}/blocks/{parent_block_id}/children to add new blocks.
  • Support block types: paragraph, heading1heading9, bullet, ordered, code, quote, callout, table.
  • Always refresh the access token before API calls if it may have expired.

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.
