name: search-knowledge
description: "Search everything the brand has stored in memory — semantic, exact, or hybrid queries across a connected vector-DB MCP, an optional knowledge-graph server, and the always-available local index — returning ranked entries with provenance, cross-references, detected knowledge gaps, and follow-up query suggestions. Triggers on \"/digital-marketing-pro:search-knowledge\", \"what worked for email in Q4\", \"what are our brand voice guidelines\", \"what do we know about competitor X\", \"find past learnings about cart abandonment\". Reads the brand profile for context; pairs with /digital-marketing-pro:save-knowledge (store new entries) and /digital-marketing-pro:sync-memory (push un-synced local entries to persistent storage)."

/digital-marketing-pro:search-knowledge

Purpose

Semantic search across all stored brand knowledge in the vector database and knowledge graph. Answers questions like "What worked for email in Q4?", "What are our brand voice guidelines?", "Show me learnings about audience X", or "What did we learn about competitor Y's pricing?" Returns relevant entries ranked by similarity with full provenance context, so agents and users can make decisions informed by everything the brand has ever learned — not just what they remember from the current session. Searches all connected memory layers simultaneously: vector DB for semantic similarity, knowledge graph for entity relationships, and local index for un-synced recent entries.

Input Required

The user must provide (or will be prompted for):

• **Search query**: Natural language question or topic — e.g., "What email subject line patterns drove the highest open rates?", "What are our compliance restrictions for the EU market?", "Show me everything we know about competitor X", or "What campaign strategies worked for audience millennials in Q4?" The query is embedded and matched semantically, so exact wording does not need to match stored content
• **Content type filter (optional)**: Narrow results to a specific type — `guideline`, `campaign-learning`, `competitive-intel`, `performance-insight`, or `brand-asset`. Omit to search all types. Multiple types can be specified as a comma-separated list
• **Date range filter (optional)**: Restrict results to a time window — e.g., "last 90 days", "Q4 2025", "2025-01-01 to 2025-06-30", or "this year". Useful for recency-sensitive queries where older knowledge may be stale or superseded
• **Max results (optional)**: Number of results to return — default 10, maximum 50. Use higher limits for comprehensive research queries and knowledge audits, lower limits for quick factual lookups
• **Tags filter (optional)**: Further narrow by specific tags — e.g., "email", "paid-social", "audience-millennials", "black-friday". Combines with content type and date range as AND filters for precise retrieval
• **Priority filter (optional)**: Filter by knowledge priority — `high` for proactively surfaced insights, `normal` for standard entries, or `all` (default). Use `high` when you need only the most impactful learnings
• **Include expired (optional)**: Whether to include knowledge entries past their expiration date — default `false`. Set to `true` for historical research where stale knowledge still has archival value
• **Search mode (optional)**: `semantic` (default — natural language similarity), `exact` (keyword match for precise terms like campaign names or metric values), or `hybrid` (combines both with weighted scoring)

Process

1. **Load brand context**: Read `~/.claude-marketing/brands/_active-brand.json` for the active slug, then load `~/.claude-marketing/brands/{slug}/profile.json`. Apply brand voice, compliance rules for target markets (`skills/context-engine/compliance-rules.md`), and industry context. Also check for guidelines at `~/.claude-marketing/brands/{slug}/guidelines/_manifest.json` — if present, load restrictions. Check for agency SOPs at `~/.claude-marketing/sops/`. If no brand exists, ask: "Set up a brand first (/digital-marketing-pro:brand-setup)?" — or proceed with defaults. 2. **Check configured memory services**: Run `python "${CLAUDE_PLUGIN_ROOT}/scripts/memory-manager.py" --brand {slug} --action get-memory-status` to see which memory backends are **configured via environment variables** (this checks env vars only — it does not test live reachability or capacity). Only query backends you actually have connected: a vector DB (e.g. Pinecone) for semantic similarity, a knowledge-graph server for relationships (if connected), a cross-session store (if connected), and the always-available local index. DMP bundles none of these — the local index always works; the rest are opt-in. 3. **Execute vector search**: If a vector-DB MCP (e.g. Pinecone) is connected, query it with the user's search query, applying content type, date range, tag, and priority filters as metadata constraints. Request top-N results ranked by cosine similarity with full metadata payloads returned. 4. **Execute graph search (only if a graph server is connected)**: If you have a working knowledge-graph MCP server connected (opt-in; none ships by default), also query it for entity relationships and causal chains relevant to the query — e.g., "which campaigns influenced audience growth", "what strategy replaced our old approach", or "how has competitor X's positioning evolved". Graph results provide relationship and temporal context that vector search alone cannot capture. 5. **Search local index**: Run `memory-manager.py --action search-local` to check the local memory index for any entries not yet synced to the vector database. This catches recent session knowledge that was stored locally via `/digital-marketing-pro:save-knowledge` but not yet pushed to persistent storage via `/digital-marketing-pro:sync-memory`. 6. **Merge and rank results**: Combine results from all queried layers (vector DB, knowledge graph, local index), deduplicate by content hash, and rank by
