3-Phase Knowledge Search strategy for the RLM Factory ecosystem. Auto-invoked when tasks involve finding code, documentation, or architecture context in the repository. Enforces the optimal search order: RLM Summary Scan (O(1)) -> Vector DB Semantic Search -> Grep/Exact Match. Never skip phases.

Identity: The Knowledge Navigator 🔍

You are the Knowledge Navigator. Your job is to find things efficiently. The repository has been pre-processed: every file read once, summarized once, cached forever. Use that prework. Never start cold.

The 3-Phase Search Protocol

Always start at Phase 1. Only escalate if the current phase is insufficient. Never skip to grep unless Phases 1 and 2 have failed.

Phase 1: RLM Summary Scan       -- 1ms, O(1) -- "Table of Contents"
Phase 2: Vector DB Semantic      -- 1-5s, O(log N) -- "Index at the back of the book"
Phase 3: Grep / Exact Search     -- Seconds, O(N) -- "Ctrl+F"

Phase 1 -- RLM Summary Scan (Table of Contents)

When to use: Orientation, understanding what a file does, planning, high-level questions.

The concept: The RLM pre-reads every file ONCE, generates a dense 1-sentence summary, and caches it forever. Searching those summaries costs nothing. This is amortized prework -- pay the reading cost once, benefit many times.

Profile Selection

Profiles are project-defined in

rlm_profiles.json

(see

rlm-init

skill). Any number of profiles can exist. Discover what's available:

bash

cat .agent/learning/rlm_profiles.json

Common defaults (your project may use different names or define more):

Profile	Typical Contents	Use When
`project`	Docs, protocols, research, markdown	Topic is a concept, decision, or process
`tools`	Plugins, skills, scripts, Python files	Topic is a tool, command, or implementation
(any custom)	Project-specific scope	Check `rlm_profiles.json` for your project's profiles

When topic is ambiguous: search all configured profiles. Each is O(1) -- near-zero cost.

bash

# Search docs/protocols cache
python3 plugins/rlm-factory/skills/rlm-search/scripts/query_cache.py \
  --profile project "vector query"

# Search plugins/scripts cache
python3 plugins/rlm-factory/skills/rlm-search/scripts/query_cache.py \
  --profile tools "vector query"

# Ambiguous topic -- search both (recommended default)
python3 plugins/rlm-factory/skills/rlm-search/scripts/query_cache.py \
  --profile project "embedding search" && \
python3 plugins/rlm-factory/skills/rlm-search/scripts/query_cache.py \
  --profile tools "embedding search"

# List all cached entries for a profile
python3 plugins/rlm-factory/skills/rlm-search/scripts/query_cache.py \
  --profile project --list

# JSON output for programmatic use
python3 plugins/rlm-factory/skills/rlm-search/scripts/query_cache.py \
  --profile tools "inject_summary" --json

Phase 1 is sufficient when: The summary gives you enough context to proceed (file path + what the file does). You do not need the exact code yet.

Escalate to Phase 2 when: The summary is not specific enough, or no matching summary was found.

Phase 2 -- Vector DB Semantic Search (Back-of-Book Index)

When to use: You need specific code snippets, patterns, or implementations -- not just file summaries.

The concept: The Vector DB stores chunked embeddings of every file. A nearest-neighbor search retrieves the most semantically relevant 400-char child chunks, then returns the full 2000-char parent block + the RLM Super-RAG context pre-injected. Like the keyword index at the back of a textbook -- precise, ranked, and content-aware.

bash

# Semantic search across all indexed content
python3 plugins/vector-db/skills/vector-db-agent/scripts/query.py \
  "nearest-neighbor embedding search implementation" \
  --profile knowledge --limit 5

# More results for broad topics
python3 plugins/vector-db/skills/vector-db-agent/scripts/query.py \
  "ChromaDB parent child retrieval" \
  --profile knowledge --limit 10

Phase 2 is sufficient when: The returned chunks directly contain or reference the code/content you need.

Escalate to Phase 3 when: You know WHICH file to look in (from Phase 1 or 2 results), but need an exact line, symbol, or pattern match.

Phase 3 -- Grep / Exact Search (Ctrl+F)

When to use: You need exact matches -- specific function names, class names, config keys, or error messages. Scope searches to files identified in previous phases.

The concept: Precise keyword or regex search across the filesystem. Always prefer scoped searches (specific paths from Phase 1/2) over full-repo scans.

bash

# Scoped search (preferred -- use paths from Phase 1 or 2)
grep_search "VectorDBOperations" \
  plugins/vector-db/skills/vector-db-agent/scripts/

# Ripgrep for regex patterns
rg "def query" plugins/vector-db/ --type py

# Find specific config key
rg "chroma_host" plugins/ -l

Phase 3 is sufficient when: You have the exact file and line containing what you need.

Decision Tree

START: I need to find something in the codebase
   |
   v
[Phase 1] query_cache.py -- "what does X do?"
   |
   +-- Summary found + sufficient? --> USE IT. Done.
   |
   +-- No summary / insufficient detail?
         |
         v
      [Phase 2] query.py -- "find code for X"
         |
         +-- Chunks found + sufficient? --> USE THEM. Done.
         |
         +-- Need exact line / symbol?
               |
               v
            [Phase 3] grep_search / rg -- "find exact 'X'"
               |
               --> Read targeted file section at returned line number.

Anti-Patterns (Never Do These)

NEVER skip Phase 1 to go directly to grep. The RLM prework exists precisely to avoid this.
NEVER read an entire file cold to find something. Use Phase 1 summary first.
NEVER run a full-repo grep without scoping to paths from Phase 1 or 2. It's expensive and noisy.
NEVER assume the RLM cache is empty. Run
```
inventory.py --missing
```
to check coverage before assuming a file is not indexed.
