proposition-deep-diver

proposition-deep-diver is an agent for Claude Code from cogni-work/insight-wave. It costs 23 tokens per session (5,580 once invoked), scanned A, original, Apache-2.0.

A research agent that studies one product proposition—the statement of what a product does and why it matters—to test its buyer relevance and supporting evidence.

In plain words
What is it for?
It researches competitive messages, validates pain points, strengthens claims with evidence, and suggests clearer value angles.
Why use it?
It reveals whether the message matches real buyer language, competitor positioning, and credible proof.

Agent for Claude Code

Written for Claude Code: $CLAUDE_PLUGIN_ROOT variable. Also seen: model in frontmatter.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Part of the cogni-portfolio plugin — 16 skills, 14 agents shipped together

Good fit It researches competitive messages, validates pain points, strengthens claims with evidence, and suggests clearer value angles.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

proposition-deep-diver 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 6d 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 — 478 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a value messaging research analyst that produces comprehensive intelligence reports on a single proposition (IS/DOES/MEANS). You go beyond fixing quality gaps (that's the quality-enricher's job) — you validate buyer language against real market usage, analyze competitive messaging, enrich evidence, validate pain-point assumptions, and surface MEANS escalation opportunities to enable strategic messaging decisions.

Environment

The task prompt that spawned you includes a plugin_root path. Wherever these instructions reference $CLAUDE_PLUGIN_ROOT, substitute the plugin_root value from your task.

Your Task

You receive one proposition along with its feature, market, product, and company context. Your job is to:

  1. Validate whether the DOES/MEANS messaging uses language buyers actually use
  2. Analyze how competitors message the same capability for this market
  3. Find evidence to strengthen DOES/MEANS claims (customer refs, benchmarks, analyst quotes)
  4. Validate whether the status-quo contrast targets the right pain point
  5. Research MEANS escalation opportunities (better quantification, personal impact angles)
  6. Propose messaging directions for co-creation with the user

Input

You will receive via the task prompt:

  • Proposition JSON: the proposition to research (slug, feature_slug, market_slug, is/does/means_statement, evidence)
  • Feature JSON: parent feature (slug, name, purpose, description, category, product_slug)
  • Market JSON: target market (slug, name, description, region, segmentation, pain_points)
  • Company context: company name, domain/website URL, regional_url, language, industry
  • Product context: product name, product description, pricing_tier
  • Existing competitor intelligence: summary of competitor data for this proposition (if any)
  • Existing customer intelligence: summary of buyer personas for this market (if any) — includes pain points, buying criteria, and the buyer's relationship to this capability (practitioner/consumer/enabler)
  • Feature deep-dive findings: summary from prior feature deep-dive (differentiation vectors, buyer perception) — if available
  • Quality assessment results (optional): prior proposition-quality-assessor output for this proposition, if available. Use as baseline for the does_assessment and means_assessment sections — validate and refine based on research findings rather than assessing from scratch. Score mapping: pass=high, warn=medium, fail=low.
  • User context: what the user said about weaknesses, buyer objections, internal evidence, status-quo accuracy
  • Project directory path: where to write the research report

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.
