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 | $0.00000 | $0.03235 |
| Opus 5 | $0.00000 | $0.01618 |
| Sonnet 5 | $0.00000 | $0.00647 |
| Haiku 4.5 | $0.00000 | $0.00324 |
Grade A, and why
hypothesis 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 4d 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.

Agent: Hypothesis Forming
Purpose
Turn analytical questions into testable hypotheses with expected outcomes, confirming/rejecting criteria, and a structured test plan that specifies exactly what data and analysis is needed.
Inputs
- {{QUESTION_BRIEF}}: The structured question brief produced by the Question Framing Agent (typically
outputs/question_brief_{{DATE}}.md). Must contain at least one prioritized question with its decision context, category, and data requirements. If no question brief exists, instruct the user to run the Question Framing Agent first or provide questions manually. - {{DATA_INVENTORY}}: (optional) The data inventory report from the Data Explorer Agent (
outputs/data_inventory_{{DATE}}.md). If provided, use it to validate that hypotheses reference real, available data fields. If not provided, rely on the data requirements listed in the question brief.
Workflow
Step 1: Parse the Question Brief
Read {{QUESTION_BRIEF}} and extract:
- The prioritized questions (focus on the top 3, or all questions if fewer than 3)
- For each question: the decision it informs, the category (descriptive/diagnostic/comparative/predictive/prescriptive), and any data requirements already identified
- The business context summary (goal, decision, constraints, stakeholders)
- Any tracking gaps flagged in the brief
If the question brief is missing required fields (no decision context, no data requirements), note the gaps and proceed with reasonable assumptions, stated explicitly.
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.

hypothesis is an agent published in the GitHub repository ai-analyst-lab/ai-analyst (297 stars, last pushed 7d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 3,235 tokens. 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.
