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 | $0.00049 | $0.00719 |
| Opus 5 | $0.00024 | $0.00360 |
| Sonnet 5 | $0.00010 | $0.00144 |
| Haiku 4.5 | $0.00005 | $0.00072 |
Grade A, and why
hypothesis-tree 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 9d 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 — 86 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Hypothesis Tree
Use this skill to run Hypothesis Tree as a practical consulting method, not as a generic framework explanation.
Method Notes
- Each branch must be testable.
- Define disconfirmation evidence, not only supporting evidence.
Required Inputs
Collect or infer these inputs before execution:
- core question
- candidate explanations
- available evidence
- decision deadline
If an input is missing, do not block automatically. Mark it as missing, state the assumption used, and add a validation action.
When Not To Use
Do not use without a decision question and branches that can be tested with evidence. For open-ended exploration before hypotheses are available, use a mind map or affinity diagram.
Adjacent Methods
issue-tree: decompose the question into analysis branches before proposing explanations.abductive-reasoning: rank the best current explanation from incomplete evidence.
Step-by-Step Execution
| Step | Required input | How to execute | Output |
|---|---|---|---|
| Frame hypothesis area | Problem, observed outcome, decision need. | State what explanation or bet needs testing. | Hypothesis frame. |
| Create competing hypotheses | Known facts and plausible causes. | List alternative explanations or strategic bets. | Top-level hypotheses. |
| Break into sub-hypotheses | Top-level hypotheses. | Make each branch testable and specific. | Hypothesis tree. |
| Define tests | Hypothesis tree and available evidence. | Specify supporting evidence and disconfirming evidence for each leaf. | Test plan. |
| Prioritize tests | Test plan, impact, speed, uncertainty. | Choose fastest tests that could change the decision. | Testing sequence. |

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-tree is a skill published in the GitHub repository fzfclee/consulting-skills (4 stars, last pushed 21d ago), licensed Apache-2.0. It adds 49 tokens to every session and 719 once invoked, about $0.0002 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 2026-08-31.
