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 | $0.00058 | $0.00732 |
| Opus 5 | $0.00029 | $0.00366 |
| Sonnet 5 | $0.00012 | $0.00146 |
| Haiku 4.5 | $0.00006 | $0.00073 |
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 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.
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 — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Hypothesis Tree
When to use
Break a problem into falsifiable root and MECE sub-hypotheses before analysis. See ../../references/hypothesis-driven-approach.md.
What this skill does not do
- Does not run analysis — names evidence needed;
workplan-builderexecutes. - Does not use topic labels as nodes — every node falsifiable.
- Does not keep branches with no so-what either direction — cut and list.
Preconditions
| Input | If missing |
|---|---|
| Problem as question | Restate and confirm before tree |
| Root hypothesis ambiguity | Present both roots; ask which to build |
Provisional mode
Uncertain root: two candidate roots with user choice; label structured first pass.
Trust spine
- Analytical Rigor (mandatory): MECE sub-hypotheses; evidence-needed per branch; cut branches listed.
- Confidence bands (
hypothesis-driven-analysis): High = triangulated evidence plan; Medium = single source; Low = assumption-driven — label load-bearing assumption. - Per
trust-conventions.mdfor sourcing, numbers, gate.
Workflow
- Restate problem as question; confirm.
- Propose falsifiable root hypothesis.
- 3–5 MECE sub-hypotheses.
- Smallest evidence test per sub-hypothesis.
- So-what if TRUE and if FALSE; cut if neither matters.
- Output as tree.
Output format
ROOT HYPOTHESIS: [falsifiable claim]
1. [Sub-hypothesis 1]
Evidence needed: [...]
If TRUE: [...]
If FALSE: [...]
...
Cut branches: [...]
Worked example
Input: "Why did mid-tier churn spike?"
Excerpt: Root: price increase caused mid-tier churn. Sub-hypothesis: elasticity >15% in segment; evidence: cohort comparison Q1 vs Q4.
Quality checks before delivering
- Falsifiable nodes only
- MECE check explicit
- Cut branches documented
- Handoff-ready for workplan-builder
Propose profile update
When a stable convention surfaces during this run (thresholds, naming, tone, output format, or recurring corrections), propose a profile update: show the exact diff against ~/.claude/plugins/config/claude-for-strategy/consulting/CLAUDE.md (org-wide facts go to org-profile.md), ask for confirmation, and write only on yes. Only /consulting:practice-setup auto-applies a full profile write.
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 daddia/claude-for-strategy (2 stars, last pushed 2mo ago), licensed MIT. It adds 58 tokens to every session and 732 once invoked, about $0.0003 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.
