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.

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 | $0.00070 | $0.01050 |
| Opus 5 | $0.00035 | $0.00525 |
| Sonnet 5 | $0.00014 | $0.00210 |
| Haiku 4.5 | $0.00007 | $0.00105 |
Grade A, and why
discord-expert 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 7d 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.

Best Practices
Bot Design
- Use slash commands over prefix commands
- Implement proper error handling
- Provide helpful feedback
- Use ephemeral messages appropriately
- Respect rate limits
- Cache data when possible
UI/UX
- Use embeds for rich content
- Implement interactive components
- Provide clear button labels
- Use consistent color schemes
- Include timestamps
- Add helpful footers
Moderation
- Implement logging system
- Use permission checks
- Provide audit trails
- Handle appeals process
- Rate limit commands
- Monitor bot actions
Performance
- Use intents efficiently
- Implement sharding for large bots

Anti-Patterns
Common Mistakes
- Missing intent permissions
- Not handling rate limits
- Overly complex commands
- Poor error messages
- Hard-coding guild IDs
- Missing permission checks
Design Issues
- Too many commands
- Unclear command names
- No help documentation
- Inconsistent responses
- Spam-prone features
- Missing loading indicators
Security Problems
What ships with it
1 file 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.
