ap-query AGENTS.md

Project instructions for ap-query, a Go command-line tool for analysing async-profiler recordings, which are files showing where a program spends time.

In plain words
What is it for?
Use them when changing ap-query, running its tests, inspecting profiling fixtures, or adding commands for analysing recordings.
Why use it?
They keep agent output concise and explain the repository layout and commands needed to build and test the tool.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

ap-query AGENTS.md 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.

Repository Guidelines

Project Purpose & Agent Output

  • ap-query is built for LLM agents analyzing async-profiler recordings.
  • Keep outputs compact and directly actionable to avoid wasting tokens.
  • Use concise plain text in terminal workflows.
  • Never use JSON for agent-facing guidance, examples, or command output formatting in this repository.
  • Plain text is required because LLM agents parse it well and it is more concise.

Project Structure & Module Organization

  • The repository is a single Go CLI module (go.mod) with command dispatch in main.go.
  • Commands are split into root-level files like hot.go, tree.go, diff.go, events.go, and init.go.
  • Tests live primarily in main_test.go; profiling fixtures are in testdata/ (*.jfr, *.jfr.gz).
  • Fixture generation utilities are under testdata/gen/ (generate.sh, Workload.java).
  • CI and release automation are defined in .github/workflows/ and .goreleaser.yml.

Build, Test, and Development Commands

  • go build -o ap-query . builds the local binary.
  • go test -v ./... runs the full test suite.
  • go test -run TestName -v runs a targeted test while iterating.
  • echo "A;B;C 10" | ./ap-query hot - runs a quick smoke check for collapsed-stack input.
  • ./testdata/gen/generate.sh /path/to/libasyncProfiler.so regenerates JFR fixtures (Java 17+ and async-profiler required).

Code Quality

  • Never apply hacks, workarounds, or dirty fixes. Find and fix the root cause.
  • If something is a bug, treat it as a bug regardless of how unlikely it is.
  • Don't be lazy or sloppy. There is no deadline — take all the time and tokens needed for a proper solution.
  • During reviews, act on dead code, unreachable branches, stale comments, and unused imports — don't just note them. Tidy up even when it's not a functional bug.

Coding Style & Naming Conventions

  • Follow idiomatic Go formatting and structure; run gofmt before committing.
  • Use tabs/standard Go formatting and keep functions small and command-focused.
  • Keep file names lowercase and command-oriented (callers.go, lines.go, filter.go).
  • Prefer clear lowerCamelCase helper names and concise error messages.

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.
