Harness-Creator: Instructions file for Codex

AGENTS.md

Harness-Creator AGENTS.md is an instructions file for Codex, OpenCode from tjdwls101010/Harness-Creator. It costs 245 tokens per session, scanned A, a copy of ols4 AGENTS.md, MIT.

Project-specific instructions for using a knowledge graph of the codebase. A knowledge graph records relationships between code concepts, files, and architecture.

In plain words
What is it for?
Use it when working in the Harness-Creator project, especially for codebase questions, relationship tracing, architecture review, and graph updates.
Why use it?
It provides rules for finding relevant code before answering questions and for updating the graph after changes.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is tjdwls101010/Harness-Creator's own configuration. It tells Codex and OpenCode how to work on Harness-Creator 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 Harness-Creator configures →

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

Harness-Creator 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.

What it actually says

graphify

This project has a knowledge graph at graphify-out/ with god nodes, community structure, and cross-file relationships.

When the user types /graphify, use the installed graphify skill or instructions before doing anything else.

Rules:

  • For codebase questions, first run graphify query "<question>" when graphify-out/graph.json exists. Use graphify path "<A>" "<B>" for relationships and graphify explain "<concept>" for focused concepts. These return a scoped subgraph, usually much smaller than GRAPH_REPORT.md or raw grep output.
  • Dirty graphify-out/ files are expected after hooks or incremental updates; dirty graph files are not a reason to skip graphify. Only skip graphify if the task is about stale or incorrect graph output, or the user explicitly says not to use it.
  • If graphify-out/wiki/index.md exists, use it for broad navigation instead of raw source browsing.
  • Read graphify-out/GRAPH_REPORT.md only for broad architecture review or when query/path/explain do not surface enough context.
  • After modifying code, run graphify update . to keep the graph current (AST-only, no API cost).
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.
