Assumption Tracker — Riskiest Assumptions Register
Invoke as $assumption-tracker.
Scans all research/*.md files, extracts implicit and explicit assumptions, ranks by risk (catastrophic if wrong) × uncertainty (how little evidence), and produces a living register prioritizing what to validate first.
Prerequisites
- Hard: At least 3 files must exist in
research/ (or research/{slug}/). If fewer exist, tell the user to run more research skills first and stop.
- Soft: The more research docs exist, the more comprehensive the register. Reads all of:
research/icp.md, research/competitive-analysis.md, research/journey-map.md, research/metrics.md, research/gtm.md, research/monetization.md, research/customer-feedback.md, research/positioning.md.
Process
0. Product-Path Scope Resolution
Resolve research scope by product path before using code or app structure as a hint:
- If
$ARGUMENTS names a non-archived research/{slug}/ directory or a product-path ID whose scope_path points there, use that path. Treat {slug} as the product/app name, not the ICP, audience, or segment label.
- If
$ARGUMENTS names only research/_archive/{slug}/ or a manifest entry with status: archived or legacy status: abandoned, stop and warn that the path is archived; do not write or update scoped outputs there.
- Read
research/.progress.yaml when present. Normalize legacy active_path to active_paths on read and write back active_paths on manifest updates. Treat legacy abandoned as archived; exclude archived, abandoned, deferred, revisit_candidate, promoted, and any scope_path under research/_archive/ from active target selection.
- If active product paths exist in the manifest, use those paths. If multiple active paths exist, ask which one to target unless this skill explicitly supports cross-path output.
- If no active manifest target exists, list non-archived product directories under
research/, excluding research/_archive/ and dot directories. Auto-select only when exactly one exists; ask when multiple exist.
- If no product directories exist, use flat
research/ single-product mode.
- Detect monorepo/app/package structure only as a secondary hint. Suggest creating a missing
research/{slug}/ product path when code clearly exposes an app, but do not require code or monorepo detection before using research/{slug}/.
When product path {slug} is active, read and write research under research/{slug}/, specs under specs/{slug}/, and treat top-level research/*.md files as flat-mode documents or cross-path summaries.
1. Load All Research
Read every research/*.md file (or research/{slug}/*.md). For each document, extract:
- Explicit claims — statements presented as facts ("our ICP has budget authority", "the market is $2B")
- Implicit assumptions — unstated beliefs the analysis depends on ("users will switch from Excel", "word-of-mouth will be a growth channel", "the aha moment happens within 5 minutes")
- Dependency assumptions — where one research doc builds on conclusions from another ("GTM pricing assumes ICP willingness-to-pay from monetization research")
Track which document and section each assumption comes from.
2. Categorize Assumptions
Group assumptions into categories:
| Category |
Examples |
| ICP & Market |
Target segment exists, pain is severe enough to pay, market size estimates |
| Value Proposition |
Our solution solves the pain, users prefer us over alternatives |
| Pricing & Revenue |
Willingness to pay, price sensitivity, unit economics viability |
| Channel & Distribution |
Can reach ICP through chosen channels, conversion rates, CAC assumptions |
| Product & UX |
Users can achieve aha moment, activation flow works, retention drivers |
| Competitive |
Competitor won't copy, switching costs exist, differentiation is durable |
| Timing |
Market is ready now, no regulatory changes coming, technology is mature |
3. Score Each Assumption
For each assumption, score two dimensions:
Risk (if wrong) — 1 to 5:
- 1: Minor inconvenience, easy pivot
- 3: Significant rework needed, delays
- 5: Existential — business model collapses, wasted months of work
Uncertainty (how little evidence) — 1 to 5:
- 1: Strong evidence — multiple data points, validated by customer feedback
- 3: Moderate — some research supports it, but not validated with real users
- 5: Pure assumption — no evidence, taken on faith or "common sense"
Combined priority = Risk × Uncertainty (max 25). Higher = validate first.
4. Check Validation Status
Cross-reference assumptions against:
research/customer-feedback.md — findings classified as "Confirmed" or "Wrong" may validate or invalidate assumptions
research/experiments/ directory — completed experiment results
research/cohort-review-*.md — real performance data
Mark each assumption's validation status:
- Unvalidated — no evidence for or against
- Partially validated — some supporting evidence, not conclusive
- Validated — strong evidence confirms this assumption
- Invalidated — evidence contradicts this assumption
- Stale — was validated, but newer data raises questions
5. Present & Validate
Present the top 10 highest-priority assumptions to the user. If the session is already in Plan mode and there are 2-3 concrete validation choices, prefer request_user_input; otherwise ask in plain text:
- Show the assumption, source document, risk score, uncertainty score, combined priority, and validation status
- Ask: "Do these priorities feel right? Any assumptions I'm missing or scoring wrong?"
- Ask: "Are there any assumptions here you already know the answer to?"
Incorporate feedback before proceeding.
6. Generate Validation Recommendations
For each unvalidated high-priority assumption (combined score ≥ 12), recommend a validation method:
| Validation Method |
Best For |
$experiment — landing page test |
Demand validation, messaging tests |
$experiment — fake-door test |
Feature demand, willingness to explore |
$experiment — pricing test |
Willingness to pay, price sensitivity |
$experiment — survey |
Broad sentiment, preference ranking |
$customer-feedback — user interview |
Deep understanding, "why" questions |
$cohort-review — analyze real data |
Post-launch metrics, funnel performance |
| Direct observation |
UX assumptions, activation flow |
| Competitor analysis |
Market timing, differentiation durability |
7. Populate Next Steps
Include 3–5 applicable items with "Pick one:" framing:
- IF unvalidated assumptions with score ≥ 15:
$experiment [top assumption] — Design a cheap test for the riskiest assumption
- IF customer feedback exists but assumptions remain unvalidated:
$customer-feedback — Gather targeted feedback on top assumptions
- IF product is live:
$cohort-review — Check if real data validates or invalidates key assumptions
- IF assumptions cross multiple docs:
$reconcile-research — Ensure research docs are internally consistent
- ALWAYS:
$research-roadmap — Check overall project status
8. Write Output
Present final register to user. Ask:
- "Ready to write this to
research/assumption-tracker.md? Anything to adjust first?"
Only after confirmation, write the output file.
Output
research/assumption-tracker.md (or research/{slug}/assumption-tracker.md)

Task Classification
When this skill produces follow-up work, file it by execution semantics:
- Immediately actionable implementation or documentation work goes in
tasks/todo.md.
- Human-only external actions tied to automated steps go in
tasks/manual-todo.md with _(blocks: Step N.X)_ or _(after: Step N.X)_; repo edits, SDK wiring, generated assets, local commands, tests, audits, and authenticated CLI/API work stay in tasks/todo.md.
- One-time condition-gated records, baselines, or future measurements go in
tasks/record-todo.md with source, condition, non-blocking reason, evidence, and promotion rule.
- Cadence-based reviews, playtests, adoption checks, investor updates, retros, or docs-health checks go in
tasks/recurring-todo.md with cadence, owner/agent, next due, evidence path, and escalation conditions.
- Do not put non-blocking records or recurring obligations in
tasks/todo.md unless they have been explicitly promoted into current execution work.
Constraints
- Read-only on research docs. Extract assumptions from existing research — do not modify source documents.
- Be specific. "Market exists" is not an assumption. "Solo creative professionals earning $50K-150K will pay $20/mo for portfolio analytics" is.
- Trace to source. Every assumption must reference the specific document and section it was extracted from.
- Score honestly. Don't inflate uncertainty to make things seem more urgent. If there's real evidence, score it low.
- Update, don't duplicate. If
research/assumption-tracker.md already exists, ask the user whether to update (re-scan and merge) or overwrite. If the session is already in Plan mode and there are 2 concrete choices, prefer request_user_input. When updating, preserve validation status and "Recently Validated" history.
- Present before writing. Never write output files until findings have been presented and validated.
