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 5.1 | $0.00150 | $0.02453 |
| Opus 5 | $0.00075 | $0.01226 |
| Sonnet 5 | $0.00030 | $0.00491 |
| Haiku 4.5 | $0.00015 | $0.00245 |
Grade C, and why
find-my-business scanned grade C 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 8d 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.

/find-my-business — Startup Idea Discovery
Interactive search process from "I don't know what to build" to "I'm working on this company." Not a business plan generator — a structured conversation that interviews, generates, validates, pushes back, and narrows toward conviction.
Step 0: Session Initialization
- Read
references/learnings.md. Summarize the 3-5 most relevant bullets for this session. - Read
references/edge-cases.mdfor any factual corrections. - Check if
business-search/state.jsonexists (adjust path to match your project structure).- Exists: Read state. Present one-paragraph summary of where we left off — current phase, active ideas, what was decided last session. Ask: "Ready to continue, or want to revisit anything?"
- Does not exist: First session. Proceed to Step 1.
- Route by phase in state file:
profileor missing → Step 1ideation→ Step 2validation→ Step 3deep-validation→ Step 4commitment→ Step 5
Step 1: Founder Profile Mining
- Read your founder context files — about-me, constraints, anti-goals, and ideal-company (adjust paths to match your project structure).
- Interview to fill gaps. Ask 3-5 targeted questions, one at a time:
- What problems have you personally experienced that frustrated you enough to complain about them?
- What industries or domains do you know deeply enough to spot what others miss?
- What makes you irrationally excited — even if it seems impractical?
- What do people come to you for help with, unprompted?
- What's an unfair advantage you have that most people don't see?
- Synthesize into a Founder Profile. Read
references/methodology.mdSection 1 for the profile template. - HUMAN CHECKPOINT: Present the profile. Flag 2-3 items marked "uncertain — correct me." Get confirmation.
- Write approved profile to
business-search/founder-profile.md(adjust path to match your project). - Execute
scripts/update_state.py --action initto create state file.

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.

find-my-business is a skill published in the GitHub repository Agent-Engineer-Master/skill-engineer (8 stars, last pushed 2mo ago), licensed MIT. It adds 150 tokens to every session and 2,453 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it C with 1 finding (hidden instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
