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 medium
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 →

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 | $0.00039 | $0.01503 |
| Opus 5 | $0.00019 | $0.00751 |
| Sonnet 5 | $0.00008 | $0.00301 |
| Haiku 4.5 | $0.00004 | $0.00150 |
Grade A, and why
add-feishu 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.
How it starts
The opening of the file, as written. The whole thing — 185 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Add Feishu Channel
This skill adds Feishu (飞书) support to NanoClaw using the skills engine for deterministic code changes, then walks through interactive setup.
Phase 1: Pre-flight
Check if already applied
Read .nanoclaw/state.yaml. If feishu is in applied_skills, skip to Phase 3 (Setup). The code changes are already in place.
Ask the user
Use AskUserQuestion to collect configuration:
AskUserQuestion: Do you have a Feishu app already, or do you need to create one?
If they have one, collect FEISHU_APP_ID and FEISHU_APP_SECRET now. If not, we'll create one in Phase 3.
Phase 2: Apply Code Changes
Run the skills engine to apply this skill's code package. The package files are in this directory alongside this SKILL.md.
Initialize skills system (if needed)
If .nanoclaw/ directory doesn't exist yet:
npx tsx scripts/apply-skill.ts --init
Apply the skill
npx tsx scripts/apply-skill.ts .claude/skills/add-feishu
This deterministically:
- Adds
src/channels/feishu.ts(FeishuChannel class implementing Channel interface) - Three-way merges Feishu support into
src/index.ts(reads credentials viareadEnvFile, creates FeishuChannel if configured) - Installs the
@larksuiteoapi/node-sdknpm dependency - Updates
.envwithFEISHU_APP_IDandFEISHU_APP_SECRET - Records the application in
.nanoclaw/state.yaml
If the apply reports merge conflicts, read the intent file:
modify/src/index.ts.intent.md— what changed and invariants for index.ts
Validate code changes
npm run build
Build must be clean before proceeding.
Phase 3: Setup
Create Feishu App (if needed)
If the user doesn't have a Feishu app, tell them:
I need you to create a Feishu bot:
- Go to Feishu Open Platform and create a new app
- Under Credentials, copy the App ID and App Secret
- Under Event Subscriptions, enable Long Connection (WebSocket) mode
- Add the event:
im.message.receive_v1(Receive messages)- Under Permissions, add:
im:message:send_as_bot(Send messages as bot)im:message(Read messages)- Publish the app (or create a version and approve it)
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

add-feishu is a skill published in the GitHub repository sugarforever/01coder-agent-skills (134 stars, last pushed 2mo ago), licensed MIT. It adds 39 tokens to every session and 1,503 once invoked, about $0.0002 per session on Opus 5. 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.
