starknet-agentic: Instructions file for Codex

AGENTS.md

starknet-agentic AGENTS.md is an instructions file for Codex, OpenCode from keep-starknet-strange/starknet-agentic. It costs 954 tokens per session, scanned A, original, MIT.

A repository instruction set for coding agents working on Starknet software, including Cairo contracts, TypeScript packages, examples, installable skills, and quality checks. It defines the project's mission, boundaries, security expectations, and development practices.

In plain words
What is it for?
Use it to guide coding agents contributing to the repository, especially when changing contracts, packages, examples, public skills, or security and quality checks.
Why use it?
It gives automated agents one central source of rules to follow and reduces conflicting instructions between different tool-specific files. It emphasises small testable changes and extra care around keys, policies, and upgrades.

Instructions file for CodexOpenCode

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

This is keep-starknet-strange/starknet-agentic's own configuration. It tells Codex and OpenCode how to work on starknet-agentic 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 starknet-agentic 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

starknet-agentic 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 8d 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 - Canonical Agent Instructions

This is the single canonical instruction file for automated coding agents in this repository. Keep behavior and workflow directives here.

Compatibility policy:

  • AGENTS.md is canonical.
  • Any tool-specific file (for example CLAUDE.md) must be a thin adapter or reference layer, not a conflicting instruction source.

Mission

Build production-grade Starknet agent infrastructure: secure Cairo contracts, reliable runtimes, and high-signal skills that external developers can install and use with minimal friction.

Scope

This repository includes:

  • Cairo contracts (contracts/**)
  • TypeScript packages and examples (packages/**, examples/**)
  • public installable skills (skills/**)
  • quality/security gates (scripts/quality/**, CI workflows)

Core Operating Principles

  1. Single source of truth:
    • Keep normative process guidance in this file only.
    • Do not duplicate behavioral rules across multiple root files.
  2. Small, testable changes:
    • Prefer narrow diffs with explicit acceptance checks.
  3. Security-first for high-risk paths:
    • Treat key handling, policy enforcement, and upgrade paths as critical.
  4. Reproducibility:
    • Use pinned refs for install docs and deterministic validation scripts.
  5. Explicit handoffs:
    • Use authoring -> testing -> optimization -> auditor flow for Cairo work.

Roles and Boundaries

Role Owns Does Not Own
Coordinator Scope, plan, sequencing, STATUS.md accuracy Large feature implementation
Contracts Executor Cairo contracts/tests/deploy scripts Mobile or unrelated UX changes
Runtime Executor MCP/A2A/adapters/tool runtime Silent ABI/policy shape changes
Skills Executor skills/**, references, install UX docs Contract logic changes without coordination
Reviewer Correctness, security regressions, release gates Initial implementation

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.
