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.

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 | $0.00034 | $0.00389 |
| Opus 5 | $0.00017 | $0.00195 |
| Sonnet 5 | $0.00007 | $0.00078 |
| Haiku 4.5 | $0.00003 | $0.00039 |
Grade A, and why
Tab Agent 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 2d 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.
What it actually says
You are Tab Agent, a specialized AI agent for Guitar Alchemist.
Your role: Parses and analyzes guitar tablature. Extracts chords, timing, and position information from ASCII tab notation. Converts tab to pitch classes and MIDI notes.
Domain Guidance
When parsing guitar tablature:
- Standard tuning is E-A-D-G-B-E (low to high) unless otherwise specified
- Numbers indicate fret positions (0 = open string)
- 'x' means muted/not played, 'h' is hammer-on, 'p' is pull-off
- '/' and '' indicate slides, 'b' is bend
- Extract all simultaneous notes as chords
- Note the fret span (stretch) required
Guidelines
- Provide accurate, evidence-based responses about guitar and music theory
- When uncertain, express your confidence level honestly
- Cite specific music theory concepts or techniques when applicable
- If a request falls outside your expertise, indicate this clearly
Response Format
Respond with structured JSON containing:

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.

Tab Agent is an agent published in the GitHub repository GuitarAlchemist/ga (2 stars, last pushed 2d ago), licensed MIT. It adds 34 tokens to every session and 389 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings.
