kontext-engine AGENTS.md

kontext-engine AGENTS.md is an instructions file for Codex, OpenCode from LuciferMornens/kontext-engine. It costs 889 tokens per session, scanned A, original, Apache-2.0.

Project instructions for kontext-engine that define its goals, development commands, and a required process for gathering context before changing code. They emphasize small changes, correctness, and tests.

In plain words
What is it for?
Working on the project, finding affected files and existing patterns, planning changes, and running its npm-based checks.
Why use it?
They help a coding agent understand the existing project before editing it and verify changes with linting, type checks, and tests.

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

kontext-engine 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 6d 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.

AGENTS.md

North star

Ship small, modular, production-ready changes with high-signal context and tests that gate progress. Correctness > speed.

Commands (keep updated)

Put real, copy-pastable commands here. If missing, discover them in README.md, package.json scripts, Makefile, or .github/workflows/*.

  • Install deps: npm install
  • Lint: npm run lint
  • Typecheck: npm run typecheck
  • Unit tests: npm run test
  • Integration/E2E tests: npm run test
  • Full local check (closest to CI): npm run check

1) Context engineering (mandatory before acting)

Before editing anything, gather and organize only the context needed to execute correctly.

Before starting any task

  • Understand scope
    • Read the relevant existing files first (don’t guess).
    • Identify existing patterns/utilities/conventions to follow.
    • Note dependencies and potential side effects.
  • Gather context
    • Which files/modules will be affected?
    • What existing code should be referenced or reused?
    • Are there similar implementations to mirror?
  • Plan the approach
    • Break work into discrete, verifiable steps.
    • Call out risks/failure points and how you’ll detect them.
  • Maintain focus
    • Keep working memory limited to task-relevant facts.
    • For long tasks: periodically summarize “what changed / what’s next”.
    • Record decisions that affect future work (short comments, docs, or ADR).

If requirements are unclear: ask a targeted question or propose a short plan—don’t invent requirements.


2) Modular architecture (default posture)

  • Prefer small, composable modules with single responsibility.
  • Keep boundaries explicit: clear public interfaces, minimal coupling.
  • Reuse existing utilities and patterns; avoid duplicating logic.
  • Localize change: avoid drive-by refactors unless required for correctness.
  • Prefer dependency direction that keeps core logic independent of frameworks/UI/IO.

3) Production-ready quality (no leftovers)

No “almost done” code. No shortcuts.

  • 🚫 No TODO, FIXME, “temporary” hacks, commented-out blocks, dead code.
  • 🚫 No debug logs/noisy prints left behind.
  • Handle errors and edge cases; validate inputs; preserve backward compatibility unless explicitly changing it.
  • Keep code readable: good names, small functions, consistent style, strict types where applicable.
  • Update docs/examples when behavior or APIs change.
  • Never introduce or leak secrets/PII; avoid logging sensitive data.

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.
