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 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 YARA Match · line 3 YARA rule matched a hack tool or exploit indicator (offensive tools, reconnaissance, privilege escalation, or exploit frameworks).Fix: Remove offensive tool references and exploit code. Legitimate agent skills should not contain penetration testing tools, exploit frameworks, or reconnaissance utilities.
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 | $0.00012 | $0.01548 |
| Opus 5 | $0.00006 | $0.00774 |
| Sonnet 5 | $0.00002 | $0.00310 |
| Haiku 4.5 | $0.00001 | $0.00155 |
Grade A, and why
slack-announce 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.

Slack Announce Skill
Generate copy-ready Slack messages for various team announcements.
When to Use
- Push PR mode: announce new PR
- Hotfix mode: urgent fix notification
- Deploy notifications
- Incident communication
Phases
Phase 1: Determine Message Type
Identify the type of announcement:
| Type | Context | Priority |
|---|---|---|
pr |
New PR created | Normal |
hotfix |
Urgent production fix | High |
deploy |
Deployment to environment | Normal |
incident |
Production issue | Critical |
Phase 2: Gather Context
Collect required information based on type:
For PR:
- Feature name (from branch or PR title)
- PR URL
- Notion task URL
- Reviewer name and handle
- Domain name
For Hotfix:
- Issue description
- Affected systems
- PR URL (if applicable)
- Urgency level
For Deploy:
- Version/tag
- Environment (test/production)
- Key changes summary
Phase 3: Select Emoji
By message type:
| Type | Primary Emoji | Secondary Emojis |
|---|---|---|
| pr (feat) | 🚀 | 📋 🔗 👀 |
| pr (fix) | 🔧 | 📋 🔗 👀 |
| pr (chore) | 🧹 | 📋 🔗 👀 |
| pr (docs) | 📚 | 📋 🔗 👀 |
| pr (refactor) | ♻️ | 📋 🔗 👀 |
| hotfix | ⚠️ | 🔥 🚨 |
| deploy | ✅ | 🎉 📦 |
| incident | 🚨 | ⚠️ 🔴 |
Phase 4: Generate Fun Closing
Select a closing that matches the PR context. Be human, be fun, be relevant.
By PR Type
Features (feat):
- "Feature flag? Where we're going, we don't need feature flags 🚗"
- "Users asked, we delivered 📦"
- "Fresh code, hot off the keyboard! ⌨️🔥"
- "Time to make some bytes dance! 💃"
- "Let's gooooo! 🎸"
Fixes (fix):
- "Bug squashed. No insects were harmed 🐛✨"
- "It's not a bug, it was an undocumented feature 📝"
- "Another bug bites the dust 🎵"
- "Sleep well tonight, this one's fixed 😴"
Refactors (refactor):
- "Same same, but different, but still same 🔄"
- "If it ain't broke... refactor it anyway ♻️"
- "Deleting code is my love language 💕"
- "Less is more. Literally, we deleted stuff 🗑️"
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.
- 9d ago First seen · 255 lines · 12 tokens per session scan A 3c89d04cc024
slack-announce is a skill published in the GitHub repository WellApp-ai/Well (340 stars, last pushed 1mo ago), licensed MIT. It adds 12 tokens to every session and 1,548 once invoked, about $0.0001 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.
