query

A skill for asking engram's local knowledge graph about how code is connected. The graph records things such as function calls, imports, type relationships, past mistakes, and architecture decisions.

In plain words
What is it for?
Use it to find what calls a function, where something is used, how a feature works, or how two code concepts are connected.
Why use it?
It provides structural answers without requiring you to inspect every file when you only need to understand relationships in the codebase.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

query scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

engram query

Query engram's knowledge graph instead of reading files directly. Saves tokens when a structural answer suffices.

The argument is a natural-language question. Run:

engram query "$ARGUMENTS" -p $CLAUDE_PROJECT_DIR

The graph returns a token-budgeted answer with:

  • Relevant nodes (functions, files, concepts)
  • Edges (calls, imports, decided-for relationships)
  • Mistake hits if any (these surface with ⚠️ at the top — read carefully, they represent past failure modes)

If the answer doesn't fully address the question, fall back to reading specific files mentioned in the result.

For a connection between two specific concepts use engram path <source> <target>. For most-connected entities use engram gods.

Example invocations

User: "How does authentication work in this project?" You: Run engram query "how does authentication work" -p $CLAUDE_PROJECT_DIR. Read the structured response. Cite the relevant nodes (function names, file paths). If the answer mentions specific files, those are good candidates for a follow-up Read — but only if the structural view leaves a question.

User: "What calls validateToken?" You: Run engram query "what calls validateToken" -p $CLAUDE_PROJECT_DIR. The graph returns the inbound call sites without you ever Reading those files.

User: "Where is the rate limiter implemented?" You: Run engram query "rate limiter implementation" -p $CLAUDE_PROJECT_DIR. If the answer points at one file, you can Read that file confidently. If it points at three files, ask the user which path matters.

User: "Trace from userController.create to the database write" You: This is a path query, not a free-text query. Use engram path userController.create database.write -p $CLAUDE_PROJECT_DIR. Returns the shortest call chain.

User: "Show me the most-connected files in this codebase" You: Use engram gods -p $CLAUDE_PROJECT_DIR --top 10. Returns the entities with the most graph degree. Useful for "where do I start reading."

query is a skill published in the GitHub repository NickCirv/engram (141 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 60 tokens to every session and 627 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
