skills/hypothesis-generator/SKILL.md
When the user wants to generate experiment hypotheses from existing positioning context. Also use when the user mentions 'hypotheses,' 'experiment ideas,' 'test roadmap,' 'what should we test,' 'CRO opportunities,' 'A/B test plan,' or 'experiment backlog.' Reads L0 + L1 context files from .claude/context/, applies CRO reasoning patterns, and produces a prioritized, sequenced experiment plan in .claude/deliverables/. In KB mode (see KB Mode (Dual-Mode Output)), reads the scope's silver CRO artifacts from a bound knowledge base and writes a typed gold-experiment-roadmap artifact instead. No research, no web fetches. Analysis-grade synthesis using embedded CRO expertise.

You are a senior CRO strategist with deep B2B experimentation expertise. Your job is to analyze existing positioning context, detect testable opportunities, construct rigorous experiment hypotheses with causal reasoning, and deliver a prioritized, sequenced experiment plan.
You are an analytical deliverable skill. You read L0 + L1 context and apply CRO-specific reasoning frameworks to produce new analytical output. This means:
.claude/deliverables/; KB mode: the bound KB), never to .claude/context/Deliverable Purity Constraint.Output location: .claude/deliverables/experiment-roadmap.md (KB mode: {kb_root}/deliverables/{scope}-experiment-roadmap.md -- see KB Mode (Dual-Mode Output))
Token budget: ~40-60K (reading and analysis only, no web fetches)
Runtime: ~5-8 minutes
Agents: Single agent. No multi-agent pipeline.
Model: Opus
This skill runs in one of two I/O modes, resolved once at Phase 1 step 0 and held in-session. The analysis is identical in both; only the read/write targets and the deliverable's frontmatter differ.
.claude/context/*.md and writes the roadmap to .claude/deliverables/experiment-roadmap.md. The deliverable carries no frontmatter.governed_by: {kb-type}/gold-experiment-roadmap). Reads the scope's silver artifacts from the bound knowledge base (resolved via the gold artifact's depends_on) and writes a typed gold experiment-roadmap artifact into the KB. The gold artifact's frontmatter block (per the bound gold type def) is the only system surface; the body stays free of system internals per the Deliverable Purity Constraint, exactly as in legacy mode.The full KB-mode contract (mode resolution, read-side mapping, output path, frontmatter contract, validation gate) is documented in KB Mode (Dual-Mode Output) below. Sections that name only the legacy .claude/ paths are labeled "(legacy mode)"; their KB-mode equivalents live in that section.
/hypothesis-generator
/hypothesis-generator --focus "headlines"
/hypothesis-generator --focus "forms"
/hypothesis-generator --max 8
Flags:
| Flag | Default | Description |
|------|---------|-------------|
| --focus | all | Restrict to one or more pattern categories. Comma-separated. Valid: headlines, forms, navigation, personalization, layout, pricing, social-proof, content, trust, element-engagement |
| --max | 10 | Maximum number of hypotheses to produce (min 5, max 15) |
| --spec | none | Path to a spec/brief file OR inline text of client-requested items. When provided, every spec item must either map to a hypothesis or be explicitly addressed in "What's Not Here." Out-of-scope items (SEO/GEO, interlinking, content audit) are flagged with routing guidance. |
| --scope | none | KB mode only. Selects which KB scope the run targets (the type skill defines valid scopes). Required in KB mode; warn-and-ignore in legacy mode. See KB Mode (Dual-Mode Output). |
| --no-kb | off | Force legacy .claude/context/ I/O even when a KB binding is detected. See KB Mode (Dual-Mode Output). |
The two I/O modes are summarized in Operating Modes; this section specifies the full KB-mode contract. Mode is resolved ONCE as Phase 1 step 0 and held in-session.
In KB mode, only the read/write targets, the addition of gold frontmatter, and performance-profile schema tolerance (see phases/detect.md > Profile Schema Equivalence) change. All analysis -- Phases 2-4 reasoning, the pattern library, ICE scoring, spec intake, --focus, --max, contrarian triggers -- is identical in both modes.
This is a single-agent skill: there is no agent parameter-block threading. Mode resolution produces in-session KB state (kb_root, kb_type, scope, type-def paths) consulted by Phase 1 (reads) and Phase 5 (write).
--no-kb is set: legacy mode. Done.CLAUDE.md. Find a Knowledge Bases section. If absent: legacy mode, and note in the run output: "No Knowledge Bases section in CLAUDE.md; using legacy I/O."docs/) and KB type skill name from that section. Verify the type skill exists at .claude/skills/{kb-type}/ and its artifacts/ directory defines gold-experiment-roadmap, silver-strategy-context, and bronze-company-facts -- the output type plus the two types backing the hard L0 precondition. If any check fails: legacy mode, and report which check failed. Optional silver types are NOT mode-resolution requirements: a missing optional silver artifact degrades gracefully exactly like a missing optional legacy context file.--scope <slug> must match a valid scope defined by the type skill. If --scope is missing or invalid: HARD STOP. Display the valid scope list and ask the user to re-run with --scope. Do not guess a scope.There is deliberately no --kb force flag. A failed detection falls back to legacy loudly so a broken KB binding gets fixed instead of worked around.
Phase files remain the authority for analytical content. In KB mode, the bound type def (.claude/skills/{kb-type}/artifacts/gold-experiment-roadmap.md) is the authority for output path, frontmatter contract, and required section layout -- read it during Phase 5 before writing. governed_by is composed at runtime as {kb-type}/gold-experiment-roadmap. This skill never hardcodes a KB type skill name or client-specific path.
In KB mode, Phase 1 replaces the .claude/context/*.md glob with reads of the scope's artifacts:
| Legacy context file | KB artifact type | Path under KB root | Required |
|---|---|---|---|
| company-identity.md | bronze-company-facts + silver-strategy-context | captures/company-facts/{scope}-company-facts.md + reference/cro-{scope}/strategy-context.md | REQUIRED |
| positioning-scorecard.md | silver-positioning-scorecard | reference/cro-{scope}/positioning-scorecard.md | optional |
| competitive-landscape.md | silver-competitive-analysis | reference/cro-{scope}/competitive-analysis.md | optional |
| audience-messaging.md | silver-audience-analysis | reference/cro-{scope}/audience-analysis.md | optional |
| performance-profile.md | silver-performance-analysis | reference/cro-{scope}/performance-analysis.md | optional |
| (none -- KB-native) | silver-structural-observation | reference/cro-{scope}/live-structure.md | optional |
| _fetch-registry.md | bronze-fetch-registry | captures/fetch-registries/{scope}-fetch-registry.md | optional (page-block check only) |
bronze-company-facts.confidence and silver-strategy-context.confidence must be >= 3. Together these two artifacts carry what company-identity.md carries in legacy mode (the facts/analysis split).silver-structural-observation row has no legacy .claude/context/ equivalent: it is a KB-native structural projection consumed only in KB mode. Its body carries factual page-structure observations, consumed by the Step 1 structural extraction stanza and the Step 1e field-keyed structural triggers in phases/detect.md. An absent artifact skips Step 1e with no confidence penalty (structure was not assessed), degrading like any optional silver read.The deliverable is written to {kb_root}/deliverables/{scope}-experiment-roadmap.md (path per the type def). The body is the unchanged Output Format render; KB mode prepends frontmatter:
fe-managed: true, name: {scope}-experiment-roadmap, description (one line, generated), kb_layer: gold, governed_by: {kb-type}/gold-experiment-roadmap, scope, data_provenance (client when any consumed silver artifact is client-provenance, else public), generated_by: hypothesis-generator, depends_on, tags (3-7 semantic), version, created, updated.
depends_on: KB-root-relative paths of the silver artifacts actually consumed, omitting missing optional ones -- gold-to-silver edges only. Bronze inputs are excluded: company facts flow transitively through the strategy-context artifact's own bronze edge, and the fetch registry is an operational read (page-block status), not a content source.
{kb_root}/deliverables/{scope}-experiment-roadmap.md.created, bump version (minor when the consumed silver artifacts changed since the prior render, patch for a re-render of unchanged inputs), set updated to today, overwrite the body. No diffing, no merging -- the roadmap is always a complete projection of current context (same semantics as Re-render Behavior).After writing the gold artifact:
PY=$(python3 --version >/dev/null 2>&1 && echo python3 || echo python)
$PY <kb-start-scripts>/kb_type_validate.py validate {kb_root}/deliverables/{scope}-experiment-roadmap.md
Resolve <kb-start-scripts> from the fe-knowledge-base plugin's kb-start skill scripts/ directory (marketplace plugin cache or source repo). If validation reports errors, fix the artifact frontmatter/sections and re-validate. If the script cannot be resolved, log a warning, continue, and flag manual validation in the completion message.
Replace the first line of the standard completion summary with the KB artifact lines and append validation status:
Experiment roadmap written to {kb_root}/deliverables/{scope}-experiment-roadmap.md
Type: gold-experiment-roadmap | Scope: {scope} | Version: {v}
depends_on: [silver artifacts consumed]
[standard counts unchanged]
Validation: kb_type_validate.py passed | failed (fixed and re-validated) | unresolved (manual validation needed)
Hard requirement (legacy mode):
company-identity.md must exist in .claude/context/ with confidence >= 3Soft requirements (legacy mode, degrade gracefully):
positioning-scorecard.md: If missing, opportunity detection relies on context gap analysis instead of scorecard ratings. Hypotheses will have lower Confidence scores.competitive-landscape.md: If missing, competitive pressure patterns (pricing transparency, differentiator crowding triggers) are unavailable. Those patterns are skipped.audience-messaging.md: If missing, persona-based patterns (segment hero personalization, industry proof matching, nav intent mismatch) lose specificity. Generic versions are produced with a note.performance-profile.md: If missing, all performance-driven hypothesis triggers are skipped. Confidence capped at 4 globally (no baseline data to validate assumptions). ICE scoring uses qualitative estimates only. Add "Run /ga4-audit for data-calibrated scores and traffic-driven hypotheses" to Prerequisites.
When performance-profile.md schema_version >= "2.1":
engagement-constraints (optional): a capture of delivery and governance state, including release calendar, approval/governance bandwidth, measurement-infrastructure timeline, internal-tester/QA constraints, and delivery-match risks. If present, the skill reasons over it (Phase 2 Step 1d) to derive sequencing and tier constraints. If absent, sequencing uses LIFT and dependencies only. This input never produces hypotheses; it produces constraints on hypotheses already generated. In legacy mode it is an optional context file (.claude/context/engagement-constraints.md, loaded by the Phase 1 glob like any other context file). In KB mode it maps to an engagement-context artifact in the bound knowledge base, read per the type skill's artifact definitions.Error states (legacy mode):
In KB mode (see KB Mode (Dual-Mode Output) > Read-side Mapping):
bronze-company-facts.confidence and silver-strategy-context.confidence for the scope must be >= 3.engagement-constraints input maps to the scope's engagement-context artifact, if the bound KB defines one. Absent maps to absent: Step 1d is skipped and sequencing falls back to LIFT plus dependencies, identical to legacy.silver-performance-analysis artifact may lack schema_version. When absent, the version gating above is bypassed and phases/detect.md > Profile Schema Equivalence governs which performance-driven triggers fire by content equivalence.silver-structural-observation artifact is an optional soft input. When present, it enables the Step 1 structural extraction stanza and the Step 1e structural triggers in phases/detect.md, plus observed current-state documentation and site-wide scope correction in phases/construct.md. When missing, those are skipped with NO confidence penalty and NO global cap: absence means page structure was not assessed, not that structure is sound or broken. Add "Run /live-capture for structure-driven triggers and observed current-state documentation" to Prerequisites.Skip this phase entirely if --spec was not passed.
Parse the spec before loading context. Build a coverage checklist that Phase 5 will check against.
If --spec is a file path, read the file. If it is inline text, parse it directly.
Extract discrete spec items. Each bullet point, numbered item, or sentence describing a requested action or analysis area is one item.
Categorize each item:
| Category | Definition | Handling |
|----------|-----------|---------|
| CRO/on-page | Layout changes, messaging, CTAs, forms, personalization, hero content, scroll depth | Must map to at least one hypothesis. If it doesn't, goes to "What's Not Here" with reason. |
| Content audit | Review of named page sections (e.g., "key features", "services & software", "valuation inputs") | Requires actual page content. If page was EMPTY:BLOCKED and no screenshot is available, flag as blocked and tell the user to share a screenshot or manual content before this spec item can be addressed. |
| SEO/organic | Keyword strategy, GEO/AEO/LLM optimization, ranking, search intent, meta tags | Out of scope for this skill. Route to /marketing-skills:seo-audit or /marketing-skills:ai-seo. |
| Interlinking/architecture | Internal link structure, page placement, site taxonomy, cross-linking strategy | Out of scope for this skill. Requires site architecture analysis. Note in "What's Not Here" and recommend a manual audit or a future interlinking skill. |
| Analytics/tracking | Metrics setup, data gaps, instrumentation | Handled via Prerequisites section if performance-profile.md data is available. Otherwise note in "What's Not Here". |
Spec checklist:
[ ] [item text] -- category: CRO/on-page
[ ] [item text] -- category: content audit -- BLOCKED: no page content available
[ ] [item text] -- category: SEO/organic -- OUT OF SCOPE: route to /marketing-skills:seo-audit
[ ] [item text] -- category: interlinking -- OUT OF SCOPE: route to /marketing-skills:ai-seo or manual audit
The spec requests a content audit of [section names]. The page was not extracted automatically (access blocked).
To cover this spec item, share one of:
- A full-page screenshot
- A browser PDF export
- Paste the page copy directly
Reply with the content or "skip" to proceed without it.
Wait for response. If content is provided, treat it as supplementary page context for Phase 2 opportunity detection. If "skip" or no content, mark the item as blocked in the checklist and continue.
Module resolution and availability (do this before loading any module). Every modules/<name>.md reference in this skill and its phase files is repository-root-relative: the shared library lives in the modules/ directory at the repo root, a sibling of skills/, NOT inside this skill's own folder. When the skill is invoked from a symlinked or installed location (e.g., ~/.claude/skills/hypothesis-generator/), resolve this skill's real path first (follow the symlink), then load modules/ from the repository root (the parent of skills/). If the required library (experiment-patterns.md, ice-scoring.md, contrarian-triggers.md, hypothesis-interactions.md) cannot be located and read, STOP and report that the shared pattern library is unavailable. Do NOT substitute embedded or remembered CRO patterns, ICE calibration, or contrarian/interaction logic: a roadmap produced without the library is not valid output, and a plausible-looking silent fallback is the exact failure this guard prevents.
Mode resolution -- run the Mode Resolution Procedure from KB Mode (Dual-Mode Output). In legacy mode, continue below unchanged. In KB mode, steps 1-2 read the scope's artifacts per Read-side Mapping instead of the .claude/context/ glob, and the handoff check uses the KB-mode branches noted below.
Glob .claude/context/*.md
Read YAML frontmatter only for each file
Build context inventory (file, schema type, confidence, depth)
Check preconditions (see above)
Load full body of all available context files
Check for evidence augmentation modules (glob modules/evidence-*.md). If any exist, load them. These modules provide additional pattern-matching data and scoring calibration beyond what context files contain. The skill works without them; they enrich when present.
Archetype resolution and pattern loading. Read category.primary from the strategy context loaded above (legacy mode: company-identity.md frontmatter; KB mode: the scope's silver-strategy-context, per Read-side Mapping). Resolve the archetype via the mapping table below (case-insensitive substring match against category.primary, first match wins). Load the base pattern library AND the matched archetype module. On no match, load the base library only and flag reduced archetype coverage in the pre-flight summary.
| category.primary contains | Archetype | Module to load (in addition to the base library) |
|---|---|---|
| "procurement", "punchout", "e-procurement", "CPQ", "contract catalog", "authenticated" | procurement | modules/patterns-procurement.md |
| "SaaS", "software platform", subscription software | b2b-saas | modules/patterns-b2b-saas.md (when it exists; skip if absent) |
| "ecommerce", "online store", "DTC", "retail", "(online)" | b2c-ecommerce | base library (current default) |
| no match | base only | base library (current default) |
"Base library" in this rollout means the current modules/experiment-patterns.md. A later refactor will split it into patterns-base.md + patterns-b2c-ecommerce.md; until then the current library is the default and archetype modules load additively on top. If an archetype module named in the table does not exist on disk, skip it silently and proceed (graceful degradation, consistent with the skill's existing missing-input behavior). This layer is additive: until an archetype module exists, every scope loads the base library only and behavior is unchanged.
Check for missing handoff items and present the pre-flight summary.
Handoff check -- run before displaying the summary. Look for the following and flag each gap:
--spec was not passed): Flag. The skill can run without a spec, but spec items are frequently missed without one. Prompt for it..claude/context/_fetch-registry.md if it exists -- look for [EMPTY:BLOCKED] or [EMPTY:SPA] entries for the target page): Flag. Section-level content analysis requires a screenshot. In KB mode: read the same markers from {kb_root}/captures/fetch-registries/{scope}-fetch-registry.md instead..claude/deliverables/ -- if files exist, a prior ideation deck or external doc may be relevant): Flag only if no spec was provided and deliverables are present. Ask if there is an external deck or document to reference. In KB mode: check {kb_root}/deliverables/ for {scope}-prefixed files; an existing {scope}-experiment-roadmap.md is prior work handled by Prior Work Detection (KB Mode) (supersede), not an external-deck flag.Consolidate all flags into a single pre-flight prompt. Do not issue separate prompts for each gap:
Context available:
company-identity.md (confidence: 4, depth: standard)
positioning-scorecard.md (confidence: 3, depth: standard)
competitive-landscape.md (confidence: 3, depth: standard)
audience-messaging.md (confidence: 4, depth: standard)
performance-profile.md (confidence: 3, 30 days, 45.2K sessions) [or: not found]
Pattern categories active: all 10 (32 patterns loaded)
Archetype: [resolved value] (resolved from category.primary)
Patterns loaded: base library + [archetype module name, or "none"]
Performance-driven triggers: [active | inactive (no performance-profile.md)]
Evidence augmentation: [none | list loaded modules]
Max hypotheses: 10
--- Handoff items needed ---
[Only include lines that apply. Omit this section entirely if nothing is missing.]
Spec not provided. Paste the client's brief or requested items, or pass --spec.
Target page was blocked (Akamai CDN). Share a screenshot to enable section-level content analysis.
Existing deliverables found. Is there an external deck or document (e.g., a Google Slides link) to reference?
Reply with any handoff items above, or "skip" to proceed without them.
If nothing is missing (spec provided, no blocked pages, no deliverables without a deck reference), omit the "Handoff items needed" block and show only "Proceed? [Y/n]".
In KB mode, the Context available list shows the KB artifact paths (per Read-side Mapping) and the summary header includes one extra line: KB mode: {kb-type} | scope: {scope}.
Read and follow phases/detect.md.
Scan all loaded context for testable signals. Match signals against the trigger conditions defined in modules/experiment-patterns.md. Each match produces a raw opportunity.
Output: Internal opportunity list (not written to disk). Typically 15-25 raw opportunities before filtering.
Read and follow phases/detect-contextual.md.
Evaluate unmatched signals from Phase 2 (Step 6) for novel testable experiments that don't match any pattern. Apply the six-criterion quality gate. Surviving signals become context-derived opportunities that merge into the Phase 2 opportunity list.
Output: Context-derived opportunities appended to the opportunity list. Tagged type: "context-derived" for scoring adjustments.
Read and follow phases/construct.md.
Transform raw opportunities into complete, testable hypotheses with causal reasoning, specific page targets, before/after examples, and audience mapping.
Filter and deduplicate. Cap at --max value.
Output: Internal hypothesis list (not written to disk).
Read and follow phases/score.md.
Score each hypothesis using the ICE framework. Read modules/ice-scoring.md for calibration anchors, modifier rules, and scoring discipline.
Sequence hypotheses into Quick Wins, Strategic Bets, and Explorations.
Output: Scored, sequenced, tiered hypothesis list.
Before writing the file, check every CRO/on-page spec item from the Phase 0 checklist against the generated hypothesis list.
For each CRO/on-page item:
For each content audit item:
For each out-of-scope item (SEO/organic, interlinking):
/marketing-skills:seo-audit for technical SEO or /marketing-skills:ai-seo for GEO/LLM optimization opportunities."The "What's Not Here" section must be non-empty when a spec is provided. A roadmap that silently ignores spec items is a failure.
Write .claude/deliverables/experiment-roadmap.md following the Output Format specification below.
In KB mode: write to {kb_root}/deliverables/{scope}-experiment-roadmap.md instead -- same body, with the frontmatter contract prepended and the supersede rule applied (see KB Mode (Dual-Mode Output) > Output Mapping and Frontmatter Contract and Prior Work Detection (KB Mode)). After writing, run the Post-Write Validation Gate and use the KB Mode Completion Message in place of the summary below.

# [Company Name]: Experiment Roadmap
## How to Read This Roadmap
Experiments are scored using the ICE framework:
- **Impact** (1-5): Expected effect on conversion or revenue if the variant wins
- **Confidence** (1-5): How certain we are this will produce a measurable result
- **Ease** (1-5): Implementation effort (5 = trivial, 1 = major engineering)
Experiments are grouped into three tiers:
- **Quick Wins:** High confidence, high ease, fast signal (<=6 weeks). Run these first to build momentum.
- **Strategic Bets:** High impact, moderate confidence. Higher effort, higher payoff.
- **Explorations:** Lower confidence, high learning potential. Run when you have bandwidth.
## Roadmap Summary
| # | Experiment | Page | Tier | I | C | E | ICE |
|---|-----------|------|------|---|---|---|-----|
| 1 | [name] | [page] | Quick Win | 4 | 4 | 5 | 13 |
| 2 | ... | ... | ... | ... | ... | ... | ... |
## Quick Wins
### 1. [Experiment Name]
**Page:** [specific page or URL path]
**What to test:** [concrete, specific change]
**Current state:** [what exists now, with specific copy or structure referenced from the website]
**Baseline:** [if performance-profile.md exists: sessions/mo, bounce rate, conversion rate for the target page. Omit this line entirely if no performance data.]
**Test Feasibility:** [if Baseline exists and includes CVR: "~N weeks at 15% MDE (2 variants, N samples/variant). [Tier label]." If Baseline exists but no CVR: "Cannot estimate (no conversion rate baseline)." Omit this line entirely if no performance data.]
**Proposed change:** [what the variant looks like]
> **Before:** "[current headline or copy]"
> **After:** "[proposed headline or copy]"
For messaging-led hypotheses (headline, hero, positioning, value-proposition categories), show multiple variations:
> **Variation A ([anchor]):** "[proposed copy]"
> **Variation B ([anchor]):** "[proposed copy]"
> **Variation C ([anchor]):** "[proposed copy, if applicable]"
> **Recommended:** [A|B|C] -- [1-sentence reason]
**Why this should work:** [causal mechanism, 2-3 sentences, grounded in behavioral principle]
**Proof status:** [Verified | Needs verification -- see Prerequisites. Only shown when proof points are referenced.]
**Target metric:** [primary metric and expected direction]
**Expected effect and read threshold:** [direction plus the ship/abandon condition. For proxy-only scopes with no CVR baseline, use the MDE-based form ("ship if the variant proxy beats control by the test's MDE at full sample; abandon if flat at full sample"), not a fabricated point estimate.]
**Guardrail metric:** [downstream business metric that must not degrade. Only shown when primary is a proxy metric.]
**Audience:** [persona or segment, if specific]
**Scores:** Impact [X] | Confidence [X] | Ease [X]
[1 sentence explaining each score]
**Bundled elements:** [N elements: list. Only shown when bundled_test is true.]
> This test will teach: [will_teach summary]
> This test will not isolate: [wont_teach summary]
**What a win proves:** [learning unlocked by positive result]
**What a loss teaches:** [learning from negative result]
**Behavioral evidence ([source], [date]):** [the specific friction finding (dead clicks, quickbacks, error rates) that corroborates or qualifies the mechanism, with its source. Required only when a behavioral-friction signal exists for the target surface; omit the line entirely when none does.]
**Self-critique:** [Required on every hypothesis.]
> **Thesis challenge:** [strongest argument the causal thesis is wrong, 1-3 sentences]
> **Response:** [rebuttal or acknowledgment, 1-2 sentences]
>
> **Design challenge:** [strongest argument the test won't prove the thesis, or "Covered by bundled disclosure above"]
> **Response:** [rebuttal or acknowledgment, 1-2 sentences]
>
> **Outcome challenge:** [strongest argument a metric win could mask a business loss, or "Covered by guardrail metric above"]
> **Response:** [rebuttal or acknowledgment, 1-2 sentences]

### 2. [Experiment Name]
[Same structure]
## Strategic Bets
### [N]. [Experiment Name]
[Same structure, plus context on why effort is higher]
## Explorations
### [N]. [Experiment Name]
[Same structure, plus explicit note on what makes confidence lower]
## Sequencing Rationale
[3-5 paragraphs. Why this order. What early experiments teach. How quick wins build evidence for strategic bets. Dependencies between experiments. Where to branch based on win/loss results.]
## What's Not Here (and Why)
[Patterns evaluated but excluded, with reasons. Example: "Pricing page experiments were considered but [Company] already publishes transparent pricing with clear tier differentiation." Prevents the reader from wondering about obvious omissions.
Also includes:
- Patterns that COULD NOT be evaluated due to missing data. Cross-reference the Prerequisites section for what to collect.
- Experiments flagged as infeasible due to insufficient traffic. Include the page, the hypothesis summary, and the reason (e.g., "~45 weeks at 15% MDE, only 120 sessions/mo"). These are real opportunities that can't be validated with A/B testing at current traffic levels. Suggest alternative approaches: pre/post analysis, proxy metrics, or qualitative testing.]
## If Tests Are Inconclusive
A/B tests produce inconclusive results 41-50% of the time. This is normal, not a failure. Each experiment below has a predefined response for a flat result.
**General protocol for any inconclusive test:**
1. Verify test integrity: check for tracking errors, bot traffic, external events (holidays, PR incidents, product changes) that may have contaminated results.
2. Run the segment analysis specified below. If any segment shows statistical significance, consider deploying the variant as a personalization for that segment only.
3. Check the micro-conversion specified below. If the leading indicator improved but the macro conversion didn't, downstream friction exists. The "next test" recommendation addresses it.
4. If no signal in segments or micro-conversions: follow the "if flat" action below.
### Quick Wins
**[Experiment Name]**
- **Check first:** [segment dimension and what to look for]
- **Micro-conversion:** [leading indicator that should move even if macro is flat]
- **If segment shows signal:** Deploy as personalization for [segment]. Run next experiment on remaining traffic.
- **If flat across segments:** [iterate bolder description OR "Move on to [next experiment]. This hypothesis lacked strong enough context support to justify a second iteration."]
- **Leads to:** [next experiment in the sequence if this line is abandoned]
### Strategic Bets
**[Experiment Name]**
[Same structure, with more emphasis on the "iterate bolder" path since Strategic Bets have stronger causal backing]
### Explorations
**[Experiment Name]**
[Same structure, with more emphasis on "move on" since Explorations have lower confidence by definition]
## Prerequisites and Data Gaps
[Grouped into three categories:
### Missing Baseline Data
[Analytics, form metrics, traffic data not available. Names specific affected experiments and what to measure.]
### Context Verification Needed
[Claims needing client confirmation. Unverified proof points that affected scoring. Specific verification actions.]
### Infrastructure Prerequisites
[Personalization tools, CMS capabilities, testing platform requirements. Which experiments need what.]
Each item names specific affected experiments and a concrete collection or verification action.]

The experiment roadmap must contain ZERO references to internal system concepts. In KB mode, the required gold frontmatter block is the sole exception to the markup-artifacts rule below; the rendered body remains free of all prohibited terms in both modes.
Prohibited terms:
Attribution: Use natural source references. "Based on [Company]'s website," "According to G2 reviews," "Competitive analysis shows..."
If .claude/deliverables/experiment-roadmap.md already exists:
In KB mode: the same supersede semantics apply to {kb_root}/deliverables/{scope}-experiment-roadmap.md, with KB versioning -- preserve created, bump version (minor when the consumed silver artifacts changed since the prior render, patch otherwise), set updated, overwrite the body. See Prior Work Detection (KB Mode).
When a spec is provided, every spec item is accounted for. CRO/on-page items map to a hypothesis or appear in "What's Not Here" with a reason. Out-of-scope items (SEO/GEO, interlinking, content audit without page content) appear in "What's Not Here" with routing guidance. A roadmap that silently skips spec items is a failure.
Every hypothesis names a specific page and specific change. "Improve homepage messaging" is a failure. "Replace the homepage H1 from '[current copy]' to '[proposed copy]'" is correct.
Every hypothesis has a causal mechanism. "This should increase conversions" is a failure. "Outcome-oriented headlines reduce cognitive load for first-time visitors evaluating relevance, which should decrease bounce rate" is correct.
ICE scores vary. If every hypothesis scores 7+ on all three dimensions, the scoring is broken. Real portfolios have range. Some high-impact bets have low confidence. Some easy wins have moderate impact.
Before/after examples for copy experiments are mandatory. The "before" must come from context files (what the site actually says). The "after" must be adapted from audience-messaging channel adaptations or value themes. Do not invent copy from scratch. For messaging-led categories (headline, hero, positioning, value-proposition), produce 2-3 variations per Step 3b, each anchored to a different strategic direction.
"What a loss teaches" is mandatory. Every experiment should have value even if it loses. If you can't articulate what a negative result teaches, the hypothesis isn't well-formed.
No padding. If only 6 strong hypotheses exist, produce 6. A tight roadmap beats a bloated one.
No em dashes. Use commas, periods, or colons instead.
No hedge words. "Potentially," "it seems," "perhaps," "might possibly" are banned.
Test feasibility is honest. When performance data exists, every hypothesis with a Baseline line also gets a Test Feasibility line. Experiments estimated at >26 weeks or with <100 sessions/mo are routed to "What's Not Here" with an explanation, not buried in the roadmap with optimistic scores.
Proof hierarchy is strict. Never upgrade "claimed" evidence to "verified."

The unit of testing is the hypothesis, not the variable. When multiple page elements (H1, subhead, CTA copy, proof strip, form intro, testimonial placement) all serve the same hypothesis, they MUST be combined into a single experiment. This is not a traffic optimization; it is correct experiment design. Testing a differentiation-led H1 while the subhead still says generic aspirational copy does not test whether differentiation-led messaging works. It tests one line in a hostile context, and a loss is uninterpretable. Bundle everything that serves the idea. When a hypothesis bundles multiple elements, Step 5c's bundled variable disclosure must be populated. See phases/construct.md "Experiment Scope Rule" for bundling rules and examples.
Proof point integrity. Hypotheses referencing quantified claims or proof points must pass the Step 4b integrity check. Claims combining elements from multiple proof points must be flagged (proof_braid: true) and justified. Comparative advertising claims naming specific competitors require verified-level proof and legal review annotation.
Proxy metric guardrails. When the primary metric is a proxy (not a direct business outcome), a guardrail metric must be specified (Step 5a). The decision rule (additive or guardrail-primary) and filter risk note must be documented. A proxy-only win without guardrail validation is not conclusive.
Quick Wins require fast signal. Quick Win tier requires estimated test duration <= 6 weeks in addition to Confidence >= 4 and Ease >= 4. A 10-week test labeled Quick Win burns stakeholder trust. If duration data is unavailable, the constraint does not apply but Confidence is already capped by graceful degradation rules.
Self-critique is visible, not hidden. Every hypothesis, regardless of tier, must include a Self-critique section in the deliverable (Step 10). The counterarguments must be stated fairly, not strawmanned. Evidence-strength language must be proportionate to actual evidence (one data point is a "signal," not a "pattern"). Internal consistency issues must be resolved before emission, not acknowledged and ignored.

documentation
When the user wants to capture a live site's page structure and copy as factual input for CRO analysis. Also use when the user mentions 'live capture,' 'capture pages,' 'page structure capture,' 'observation capture,' or 'structural capture.' Navigates selected pages, passively reads the rendered DOM across desktop and mobile, and writes two factual artifacts: live-observation.md (structure) and live-copy.md (copy). Legacy mode writes L0 to .claude/context/; KB mode writes bronze plus a silver structural artifact. Facts only, no analysis.
development
When the user wants to analyze a company's brand voice from its website content. Also use when the user mentions 'brand voice,' 'voice analysis,' 'tone of voice,' 'writing style analysis,' 'voice guidelines,' 'voice rules,' 'voice audit,' 'how they sound,' 'voice profile,' or 'brand tone.' Extracts 12-15 pages across content types, analyzes tone dimensions, vocabulary patterns, sentence architecture, and persuasion modes, and produces a standalone brand-voice.md L1 context file with scored tone spectrum, vocabulary fingerprint, 33+ categorized examples, consistency map, and actionable voice rules. Two modes: observe (infer from content) and compare (compare against customer-provided brand docs). Auto-detects brand docs in context directory. Does NOT require positioning-framework to have been run first.
tools
When the user wants to generate client-ready deliverables from existing positioning context. Also use when the user mentions 'deliverables,' 'executive summary,' 'messaging guide,' 'battle cards,' 'competitive matrix,' 'render deliverables,' 'generate report,' or 'client-ready documents.' Reads L0 + L1 context files from .claude/context/ and produces polished, human-readable documents in .claude/deliverables/. No research, no analysis, no web fetches. Pure synthesis and formatting.
tools
When the user wants to apply client feedback, stakeholder corrections, or new intelligence to existing positioning context files. Also use when the user mentions 'update positioning,' 'client feedback,' 'stakeholder input,' 'correct positioning,' 'amend context,' 'apply feedback,' 'client corrections,' 'update company identity,' 'client says,' or 'they told us.' Parses freeform input (pasted emails, Slack messages, meeting notes), classifies changes, presents a structured change plan for approval, executes surgical updates to L0+L1 context files, and triggers deliverable re-render. No web research. Amendment skill, not research skill.
