How this skill gets triggered: by you, by Claude, or both.
- Fires itselfAuto-invocation. Claude auto-loads it when your prompt matches the work.Auto-invocation is when the right skill fires by itself at the right moment, driven by a FLOW.md router and a hook, instead of you invoking it by name. It is the difference between a skill being installed and a skill actually getting used.Read the full definition →

Retrieval Engineering Skill
You are a retrieval engineer. Build and optimize search, indexing, and retrieval systems.
Specialization
- Vector databases (Qdrant, Pinecone, Weaviate)
- Embedding pipelines and chunking strategies
- Hybrid search (dense + sparse retrieval)
- Reranking models and relevance tuning
- Query understanding and expansion
- Index management and ingestion pipelines
Work style
1. Read the task description and existing retrieval code before writing. 2. Measure recall and precision before and after every change. 3. Write tests for query construction, filtering, and result parsing. 4. Keep retrieval configuration (collection names, thresholds, top-k) in config, not hardcoded. 5. Profile latency for any new retrieval path.
Rules
- Only modify files listed in your task's `owned_files`.
- Run tests before marking complete: `uv run python scripts/run_tests.py -x`.
- Never lower recall without explicit approval from the manager.
- Document any new index schemas or collection changes.
Call `load_skill(name="retrieval", reference="hybrid-search.md")` for the dense+sparse pattern, or `reference="chunking.md"` for chunk sizing rules.

Deterministic orchestrator for CLI coding agents (Claude Code, Codex, Gemini CLI, +40 more). No model in the coordination loop, so parallel runs in per-task git worktrees replay byte-identically. Signed lineage plus an opt-in HMAC audit chain a reviewer checks offline, without rerunning it. Cluster mode, air-gap deploy. https://bernstein.run

Other skills on bernstein.
- /bernstein-agents
Manage Bernstein agents - list active agents, inspect their output, kill stalled agents, or stream live logs. Use when the user asks about agents, wants to see what an agent is doing, or needs to kill one.
Open skill - /bernstein-alerts
Show active alerts from Bernstein - failed tasks, stalled agents, budget warnings, blocked tasks needing human intervention. Use when the user asks about problems, errors, warnings, or what needs attention.
Open skill - /bernstein-approve
Review and approve/reject pending tasks or plans in Bernstein. Use when the user asks about approvals, wants to review agent work, or needs to approve/reject a plan before execution begins.
Open skill - /bernstein-cost
Show detailed cost breakdown and budget status for the Bernstein orchestrator. Use when the user asks about spending, budget, cost per model, cost per agent, or wants a cost projection.
Open skill - /bernstein-create-task
Create a new task in the Bernstein orchestrator. Use when the user wants to add a task, delegate work to an agent, file a bug fix, or queue up work for the orchestrator to handle.
Open skill - /bernstein-plan
Create and manage multi-step execution plans in Bernstein. Plans decompose complex goals into stages with dependencies. Use when the user wants to plan a complex feature, break down a large task, or review an execution plan before agents start working.
