Portfolio Claim Verification

Verify web-sourced claims submitted by portfolio research agents against their cited sources. This is the quality gate between enrichment and communicate.

Core Concept

Plugin root resolution. Bash invocations below resolve the plugin root inline as ${CLAUDE_PLUGIN_ROOT:-$(ls -td "$HOME"/.claude/plugins/cache/insight-wave/cogni-portfolio/*/ | head -1)} — the first call works whether or not the harness injects $CLAUDE_PLUGIN_ROOT. Keep the inline form in every call; do not strip it.

Research agents (market-researcher, competitor-researcher, proposition-generator) pull data from the web — market sizes, growth rates, competitor claims, industry benchmarks. Each web-sourced fact is logged as a claim in cogni-claims/claims.json with its source URL. But web data goes stale, gets misread, or comes from unreliable sources.

Verification catches these problems before they propagate into deliverables. The claim-verifier agent revisits each source URL, compares what was claimed against what the source actually says, and flags deviations by severity. A "TAM of $4.2B" that the source actually quotes as $2.4B is a critical deviation — it would undermine every proposal built on that number.

This matters because downstream outputs (synthesis, exports, proposals) inherit whatever the portfolio contains. Catching a wrong number here is cheap; catching it in a client presentation is expensive. The verification gate gives the user a clear picture of data quality and the chance to correct problems while they're easy to fix.

Prerequisites

This skill requires the cogni-claims plugin. If the cogni-claims:claims skill is not available, inform the user and provide installation guidance.

If no cogni-claims/ directory exists in the project, no claims have been submitted yet. Research agents submit claims automatically when web search is used during market research, competitor research, and proposition generation. Suggest running those skills with web research enabled first.
