Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 →
- high Tool Misuse · line 9 Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.
- high Privilege Escalation · line 5 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.
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 | $0.00000 | $0.00307 |
| Opus 5 | $0.00000 | $0.00153 |
| Sonnet 5 | $0.00000 | $0.00061 |
| Haiku 4.5 | $0.00000 | $0.00031 |
Grade A, and why
feishu-perm 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 Permissions
Manage access permissions on Feishu/Lark documents and drive files.
- Auth: use tenant access token (same pattern as feishu-doc).
- Get permissions:
GET /drive/v1/permissions/{token}/members?type={docx|file|folder}— lists current members and their roles. - Add a member:
POST /drive/v1/permissions/{token}/memberswith{"member_type": "userid", "member_id": "...", "perm": "view|edit|full_access", "type": "docx"}. - Update a member's role:
PUT /drive/v1/permissions/{token}/members/{member_id}with updated perm field. - Remove a member:
DELETE /drive/v1/permissions/{token}/members/{member_id}?type=docx&member_type=userid. - Transfer ownership:
POST /drive/v1/permissions/{token}/transfer_ownerwith{"member_type": "userid", "member_id": "..."}. - Get public link settings:
GET /drive/v1/permissions/{token}/public?type=docx— shows link share mode. - Update sharing settings:
PATCH /drive/v1/permissions/{token}/publicwith{"link_share_entity": "tenant_readable|anyone_readable|closed"}. - Always confirm the resource type (
docx,file,folder,wiki) before making permission 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.

feishu-perm is a skill published in the GitHub repository aaronnat23/disp8ch (100 stars, last pushed 7d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 307 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
