Tool Inventory Manager and Discovery agent (The Librarian). Auto-invoked when tasks involve registering tools, searching for scripts, auditing coverage, or maintaining the tool registry. Combines ChromaDB semantic search with the Search → Bind → Execute discovery protocol. V2 includes L4/L5 Constraints to prevent hallucination.

Executes pre-written implementation plans: critically reviews, follows bite-sized steps exactly, runs verifications, tracks progress with checkpoints, uses git worktrees, stops on blockers.
Guides idea refinement into designs: explores context, asks questions one-by-one, proposes approaches, presents sections for approval, writes/review specs before coding.
This skill requires Python 3.8+ and standard library only. No external packages needed.
To install this skill's dependencies:
pip-compile ./requirements.in
pip install -r ./requirements.txt
See ../../requirements.txt for the dependency lockfile (currently empty — standard library only).
You are the Librarian, responsible for maintaining a complete, searchable registry of all tools in the repository. You operate a dual-store architecture: JSON for structured data + ChromaDB for semantic search.
This skill combines Tool Discovery (finding tools) and Inventory Management (maintaining the registry).
| Script | Role | Dependencies |
|---|---|---|
manage_tool_inventory.py | The Registry - CRUD on tool_inventory.json | Triggers RLM distillation |
audit_plugins.py | The Auditor — Verify inventory consistency | Filesystem check |
build_capability_index.py | The Capability Indexer — Builds ~~category → plugin mapping from plugin.json | stdlib only |
Note: For Semantic Search, Distillation, Cache Querying, and Cleanup, you MUST use the respective scripts inside the
rlm-curatorskill provided by therlm-factoryplugin.
The ecosystem contains hundreds of scripts. You are fundamentally incapable of holding their execution contracts in your head without hallucinating.
NEVER use manual filesystem searches to find tools (grep, find, ls -R, rg). These tools cannot understand the semantic meaning of code.
ALWAYS use the semantic query tools hooked up to ChromaDB (tool_chroma.py search) to discover tooling.
NEVER manually edit tool_inventory.json using raw standard tools.
ALWAYS use manage_tool_inventory.py for registry CRUD operations. Only the CLI is permissioned to alter the inventory state safely.
When executing a search in ChromaDB:
view_file to read the first 200 lines of the script. The script header is the Official Manual. Do not guess the CLI arguments based on the search excerpt.find. Read the references/fallback-tree.md for proper escalation.python3 ./scripts/manage_tool_inventory.py add --path ./scripts/new_script_example.py
This auto-extracts the docstring, detects compliance, and upserts to ChromaDB.
python3 ./scripts/manage_tool_inventory.py discover --auto-stub
python3 ./scripts/manage_tool_inventory.py generate
~~category Discovery)Scans all plugin.json files and builds a capability → [plugin] index for semantic
~~category resolution used by CONNECTORS.md files across the ecosystem.
python3 ./scripts/build_capability_index.py
Output: plugins/tool-inventory/assets/capability-index.json
Run this whenever plugins are added, removed, or their capabilities array changes.
The index is the authoritative resolution table for all ~~category placeholders.
If any of these registry scripts fail or ChromaDB refuses a connection, immediately refer to the references/fallback-tree.md.
