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: 1 finding, 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 →
- medium Data Exfiltration · line 26 Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.
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 | $0.00079 | $0.00584 |
| Opus 5.5 | $0.00032 | $0.00234 |
| Sonnet 5.5 | $0.00016 | $0.00117 |
| Haiku 4.5 | $0.00008 | $0.00058 |
Grade A, and why
webhooks scanned grade A with 1 finding 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 1mo 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.

curl -s -X POST "$WEBHOOK_URL" -H "Content-Type: application/json" \ What it actually says
Webhooks / Automation
Fire outbound webhooks to integrate ChatCLI with anything that accepts HTTP — Slack/Discord incoming webhooks, Zapier/Make/n8n, custom endpoints. Keyless: it uses the webhook URLs/secrets the user provides.
Generic JSON POST
curl -s -X POST "$WEBHOOK_URL" -H "Content-Type: application/json" \
-d '{"event":"build.done","status":"green"}'
Slack / Discord incoming webhooks
# Slack
curl -s -X POST "$SLACK_WEBHOOK_URL" -H "Content-Type: application/json" \
-d '{"text":"Deploy finished ✅"}'
# Discord
curl -s -X POST "$DISCORD_WEBHOOK_URL" -H "Content-Type: application/json" \
-d '{"content":"Deploy finished ✅"}'
(If you just need to message a chat the gateway already manages, prefer the @send tool / the
send-message skill instead of a raw webhook.)
Zapier / Make / n8n
These expose a "catch hook" URL — POST your payload as JSON; the platform's scenario does the rest. Match the field names the scenario expects.
Signed webhooks (verify inbound)
When the user receives webhooks (e.g. via ChatCLI's gateway webhook adapter), verify the HMAC:
compute HMAC-SHA256(secret, raw_body) and compare to the signature header in constant time.
Document which header the sender uses (X-Hub-Signature-256, X-Signature, etc.).
Scheduled / recurring
For "fire this webhook every morning" or "after X happens", pair with @scheduler (timing) and
this skill (the HTTP call).
Rules
- Never log full secrets/URLs; treat webhook URLs as credentials.
- Confirm the destination before POSTing to an unfamiliar URL — webhooks trigger real actions.
- Check the response status; report success/failure with the HTTP code.
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.
- 1mo ago First seen · 64 lines · 79 tokens per session scan A c963d24e7749
webhooks is a skill published in the GitHub repository diillson/chatcli (94 stars, last pushed yesterday), licensed Apache-2.0. It adds 79 tokens to every session and 584 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
