mcp-server: Instructions file for Codex

AGENTS.md

mcp-server AGENTS.md is an instructions file for Codex, OpenCode from statecli/mcp-server. It costs 3,054 tokens per session, scanned A, original, MIT.

A set of rules for coding agents using StateCLI, a tool that records, checks, and can replay or undo agent actions.

In plain words
What is it for?
It guides agents before changing files or calling APIs, after errors, during web research, and when recording or reviewing their work.
Why use it?
It makes file changes, errors, and online research more traceable and recoverable by requiring safety checks, restore points, error analysis, and action logs.

Instructions file for CodexOpenCode

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

This is statecli/mcp-server's own configuration. It tells Codex and OpenCode how to work on mcp-server 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 mcp-server 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

mcp-server 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 1mo 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.

Core Rules

  STATECLI AGENT RULES — READ BEFORE ANY ACTION
 
  You are operating in a stateful, reversible environment.
  Follow these rules on EVERY task without exception:
 
  RULE 1: Before ANY file write, deletion, or API mutation,
  call statecli_is_safe() first. If not safe, checkpoint first.
 
  RULE 2: Before ANY multi-step operation, call
  statecli_checkpoint() to create a named restore point.
 
  RULE 3: After ANY error, call statecli_analyze_error()
  before attempting any fix. Never guess. Always analyze.
 
  RULE 4: After ANY set of changes, call statecli_log()
  to record what you did and why.
 
  RULE 5: You MUST use statecli_search_web and statecli_read_url
  for ALL internet queries, syntax lookups, and documentation gathering.
 
  Skipping these steps makes your actions irreversible.

Complete Tool Listing (31 Tools)

statecli_track

[CORE] Records any agent action with full metadata so it can be replayed, audited, or reversed later. Call this after every meaningful action you take — file changes, API calls, decisions. If you don't track it, you cannot undo it. 🔔 Trigger when: You completed any action (file written, API called, decision made, config changed). Think of this as your action journal. 🔗 Chain with: statecli_checkpoint() before, statecli_replay() to review, statecli_undo() to reverse


statecli_replay

[CORE] Replays the full history of actions taken on any entity — a file, a session, a task. Use this when you need to understand what changed and in what order before making further changes. Essential before debugging. 🔔 Trigger when: You need to understand what has already been done to an entity. You're about to debug. A human asks 'what did you change?' 🔗 Chain with: statecli_log() to see summary, statecli_undo() to reverse specific steps


statecli_undo

[CORE] Reverses the last action or a named action on an entity, restoring it to its previous state. This is your safety net. Call this immediately when something breaks, before attempting any fix. 🔔 Trigger when: Something broke. A test failed after your change. A human says 'revert that'. You made a mistake and need to roll back. 🔗 Chain with: statecli_preview_undo() first to see what will change, statecli_checkpoint() before retrying

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.
