query-code

query-code is a skill for Claude Code, Codex from djscheuf/agentic-dev-ecosystem-template. It costs 37 tokens per session (373 once invoked), scanned A, original, MIT.

A code-reading skill that searches a project's source directory for existing patterns related to a task. It reports relevant files and says when the code contains no matching context.

In plain words
What is it for?
Use it when a task mentions a service, feature, endpoint, or other technical area that may already have related code.
Why use it?
It helps the agent understand how the project already works before changing code, reducing guesswork and duplicate implementations.

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-code 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 1mo 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.

What it actually says

Code Query

Before touching the code, check what related code already exists.

When to Run

  • As part of assessing current project state.
  • Any task that mentions a specific service, feature, or endpoint
  • Not needed for: trivial one-liners, docs-only typo fixes, mechanical rename tasks

Process

  1. Read the task description carefully.
  2. Identify relevant domain terms from the task description.
  3. Grep src/ for keywords from the task description — service names, feature names, technical terms.
  4. Read matching files in parallel. Don't read all of src/ — only the ones that match.
  5. Summarize what's relevant in 3–5 bullets for the user, each citing the file path.
  6. If the src/ is silent on the topic, say so explicitly. Don't make things up.

Output Format

Code context for <task>:
- [src/ui/services/payment.ts] Payment service handles charge creation and refund operations
- [src/api/models/transaction.cs] Transaction model includes status and timestamp fields
- [src/scripts/seed_data.cs] Seed data script for initializing transaction records
- Nothing in src/ about <specific-subtopic>; proceeding without prior context.

Never

  • Read all of src/. It grows over time; bounded reads only.
  • Skip this step "to save tokens" on a real task. One minute of code context saves an hour of wrong-direction work.
  • Paraphrase code content as if it were your own knowledge. Always cite the file path.
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
