dhpk: Instructions file for Codex

AGENTS.md

dhpk AGENTS.md is an instructions file for Codex, OpenCode from hmj1026/dhpk. It costs 1,560 tokens per session, scanned A, a copy of claude-code-trace AGENTS.md, MIT.

Project instructions for using GitNexus, a code-analysis tool that maps symbols, relationships, and execution flows in a codebase.

In plain words
What is it for?
Finding related code, checking callers and affected processes, measuring edit risk, and verifying changes before committing.
Why use it?
They help the assistant understand dependencies and assess the possible impact of edits before changing code.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions CLAUDE.md; mentions AGENTS.md; mentions Codex.

This is hmj1026/dhpk's own configuration. It tells Codex and OpenCode how to work on dhpk itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything dhpk configures →

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

dhpk 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 yesterday.

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.

Origin

This is a copy

80% identical to claude-code-trace AGENTS.md — 83 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

GitNexus — Code Intelligence

This project is indexed by GitNexus as dhpk.

Index stale? Run node .gitnexus/run.cjs analyze --skip-agents-md from the project root to refresh the index while preserving repository guidance. Check analyze --help before using version-specific options. No .gitnexus/run.cjs yet? Bootstrap with npx, bunx, or pnpm dlx — e.g. bunx gitnexus@latest analyze --skip-agents-md (npm 11 npx crash; #1939).

Always Do

  • MUST run impact before editing. Use impact({target: "symbolName", direction: "upstream"}) or node .gitnexus/run.cjs impact "symbolName" --direction upstream --repo .; report callers, processes, and risk. Never substitute grep for graph analysis.
  • MUST analyze graph changes before committing. Use detect_changes({scope: "all"}) (MCP) or node .gitnexus/run.cjs detect-changes --scope all --repo . (CLI fallback). partial: true or truncated: true is not a clean check — a zero means unseen, not unaffected; re-run it. For regression review: detect_changes({scope: "compare", base_ref: "main"}) or node .gitnexus/run.cjs detect-changes --scope compare --base-ref "main" --repo ..
  • MUST warn on HIGH/CRITICAL risk pre-edit; never use riskSharedAxes to waive a HIGH/CRITICAL risk warning. Compare File/symbol: MCP File omits axes; Graph-RAG expands File.
  • MUST treat risk: UNKNOWN as unresolved, not as low. An empty caller set is not evidence the symbol is unused — it can also mean the callers are not resolvable by the index (plain-object property access, dynamic dispatch, cross-language calls). impact pairs UNKNOWN with a riskNote saying so. Confirm with a text search before treating the symbol as safe to change or delete; do not proceed on the strength of a zero.
  • MUST use query({query: "concept"}) for concepts/flows, context({name: "symbolName"}) for a named symbol, or impact for blast radius, on read-only callers, dependencies, imports, or execution flow. Graph first; text search only for empty/UNKNOWN/literals.
  • For security review, explain({target: "fileOrSymbol"}) lists taint findings (source→sink flows; needs analyze --pdg).

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.
