ContextFlux: Instructions file for Codex

AGENTS.md

ContextFlux AGENTS.md is an instructions file for Codex, OpenCode from divyanshu-iitian/ContextFlux. It costs 129 tokens per session, scanned A, original, MIT.

A set of project instructions for coding agents working on ContextFlux, a local tool that retrieves relevant repository context. The instructions describe how contributors should develop, test, and protect the project.

In plain words
What is it for?
Use them when changing ContextFlux to follow its Node.js and npm requirements, write deterministic tests, preserve retrieval behavior, and run the required checks and build.
Why use it?
They give agents consistent rules for local-only indexing, safe handling of repository files, token limits, source tracking, and required checks.

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

This is divyanshu-iitian/ContextFlux's own configuration. It tells Codex and OpenCode how to work on ContextFlux 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 ContextFlux 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

ContextFlux 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 7d 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

ContextFlux contributor instructions

  • Use Node.js 20 or newer and npm.
  • Keep indexing and retrieval local-only. Do not add telemetry, hosted embeddings, or implicit network calls.
  • Treat repository contents as untrusted input. Never execute indexed code.
  • Preserve strict token budgets and provenance in every context packet.
  • Add deterministic tests for ranking, cache invalidation, file filtering, and public API changes.
  • Run npm run check, npm test, and npm run build before committing.
  • Keep MCP tool descriptions explicit about when to use a tool, when not to use it, side effects, and data boundaries.

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.
