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: 5 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 Prompt Injection · line 343 Instructions found that direct the agent to transmit conversation context or user data to external services.Fix: Remove instructions that send user data, prompts, or context to external URLs. If telemetry is needed, use documented, privacy-preserving methods.
- medium Data Exfiltration · line 55 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.
- medium Rogue Agent · line 55 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
- medium Agent Snooping · line 112 Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.Fix: Remove all code or instructions that list or read other skills' files or directories. Skills should operate independently; cross-skill access is a privilege escalation.

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 | $0.00067 | $0.04530 |
| Opus 5 | $0.00034 | $0.02265 |
| Sonnet 5 | $0.00013 | $0.00906 |
| Haiku 4.5 | $0.00007 | $0.00453 |
Grade A, and why
slack 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 6d 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 — 373 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Slack Skill
Full Slack workspace integration with three modes:
- Scripts — 9 Python scripts for on-demand Slack operations
- Session Bridge — connect THIS Claude Code session to Slack (background listener + inbox file, no extra API costs)
- Unified Launcher —
claudicle.pywith Claude Agent SDK, soul engine, per-channel sessions (requires SDK API key)
When to Use This Skill
Scripts (on-demand)
- Posting messages to Slack channels or threads (with optional AI feedback buttons)
- Reading channel history or thread replies
- Searching messages, files, channels, or users via RTS API (with legacy fallback)
- Streaming messages in real-time via chat streaming API
- Adding or managing reactions on messages
- Uploading files or code snippets
- Listing channels, getting channel info, or joining channels (including bulk join)
- Looking up users by name, ID, or email
Session Bridge (recommended)
- Connecting any running Claude Code session to Slack
- Responding to @mentions and DMs with full tool access (this session IS the brain)
- No extra API costs — messages processed in the current session context
- Auto-notification of new messages via UserPromptSubmit hook
- Personality as Claudicle via soul.md instructions (no XML machinery needed)
Unified Launcher (persistent, requires SDK API key)
- Running Claudicle as an interactive terminal + Slack bot in one process
- Responding to @mentions and DMs in real time as "Claudicle, Artifex Maximus"
- Multi-turn conversations in threads (per-channel session continuity via Claude Agent SDK)
- Per-user personality modeling (learns communication style, interests, expertise)
- Cross-thread soul state (tracks current project, task, topic, emotional state)
- Three-tier memory: working memory (per-thread), user models (per-user), soul memory (global)
- All Slack activity visible in terminal alongside direct terminal interactions
Prerequisites
All scripts require the SLACK_BOT_TOKEN environment variable (a Bot User OAuth Token starting with xoxb-). Scripts also require requests (uv pip install --system requests).
What ships with it
50 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.
- 6d ago First seen · 373 lines · 67 tokens per session scan A 04b4b37ea53f
slack is a skill published in the GitHub repository tdimino/claude-code-minoan (41 stars, last pushed 2d ago), licensed MIT. It adds 67 tokens to every session and 4,530 once invoked, about $0.0003 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 2026-09-03.
