Code-Ledger: Instructions file for Codex

AGENTS.md

Code-Ledger AGENTS.md is an instructions file for Codex, OpenCode from mikuare/Code-Ledger. It costs 6,263 tokens per session, scanned A, original, MIT.

A set of instructions for coding agents working in the Code-Ledger repository. It defines how agents should consult CodeLedger before reading or changing source files.

In plain words
What is it for?
It is for guiding agents through task clarification, repository orientation, pre-action checks, and verification using the CodeLedger command or service.
Why use it?
It helps prevent agents from guessing which part of a repository a request concerns and from relying on an outdated view of the code.

This is mikuare/Code-Ledger's own configuration. It tells Codex and OpenCode how to work on Code-Ledger 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 Code-Ledger 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

Code-Ledger 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.

How it starts

The opening of the file, as written. The whole thing — 188 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CodeLedger Protocol

One call before you start

Make one call before reading source files or editing anything (CLI: codeledger brief "<the user's request>"; MCP: codeledger_start_task). Pass the user's request in their own words — do not rewrite it, and do not summarise it first.

It answers do_next and gives you the exact next command:

  • ASK_USER — the repository cannot settle something the request leaves open: which area is meant, or how widely a shared change applies. The questions come with options drawn from the index. Ask the user. Do not choose one silently — picking an interpretation and working on it is the most expensive mistake available here, and it is invisible until the work is finished. When they answer, call again with their answer as --understanding/understanding, in your own words.
  • CONFIRM — the target is settled and there is something worth agreeing on first. State what you understand the task to be — what will change, what will not, how it will be verified — and call again with it as understanding. CONFIRMED means your restatement is consistent with the request and names only code this project has. It does not mean the reading is right; only the user can say that.
  • RESUME — this task has been worked on before. Read next_action and failed_attempts before anything else. Those are approaches already known not to work.
  • RECONSIDER — previous attempts changed no symbol, or changed the same symbols repeatedly while verification still failed. Editing again is unlikely to help.
  • PROCEED_WITH_CARE / PROCEED — the target is settled and its footprint is measured. Read what is in scope, then submit your plan to codeledger handshake.

brief composes resume, clarify, check and progress. Each is still available on its own; the composition exists so the pre-change reading is one call rather than four, because the step that is four calls deep is the step that does not happen.

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.
