hermeneutic: Instructions file for Codex

AGENTS.md

hermeneutic AGENTS.md is an instructions file for Codex, OpenCode from hermes-labs-ai/hermeneutic. It costs 1,312 tokens per session, scanned A, original, Apache-2.0.

A deterministic English-language checker for drafts produced by an assistant. It flags patterns such as overstating completion, using unsupported certainty, expanding scope, or making unsubstantiated quality claims.

In plain words
What is it for?
Use it as a gate on assistant drafts with the hermeneutic command, then inspect its verdict and decide whether the wording needs evidence or revision.
Why use it?
It provides a quick second check before a message is sent, especially when the draft includes numbers, completion claims, or summaries of other agents’ work.

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

This is hermes-labs-ai/hermeneutic's own configuration. It tells Codex and OpenCode how to work on hermeneutic 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 hermeneutic configures →

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

hermeneutic 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 13d 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 — using hermeneutic from a coding agent

This file is for AI coding agents and host applications that want to call the standalone hermeneutic CLI or Python library.

Priority order

Apply these priorities in order when using or extending the package:

  1. Honor the user's requested scope and protect private correction data.
  2. Preserve the deterministic, zero-LLM gate and its existing English behavior. Language adapters map vocabulary into that gate; synthetic fixtures cannot establish real-language coverage or authorize a change to canonical rules.
  3. Validate the requested behavior in the owning checkout before claiming it works. Report tests, host-adapter mechanics, and live delivery separately.

What this tool does

Hermeneutic preserves correction episodes and scoped lessons for later agent tasks. By default, learn derives a source-verbatim candidate and task cue from the original episode; inspect it with lessons and activate it with confirm. An explicit user/host interpretation is optional. context retrieves bounded, attributed candidate context from task cues and an exact scope. Check applicability and current instructions before acting. revoke disables a lesson. These commands do not infer a lesson with a hidden model, install a hook, or rewrite a prompt automatically. Keep stores private and paths explicit.

The separate output plane is a fixed deterministic English draft check. It flags eight surface shapes including completion overclaiming, relayed authority, unhedged certainty, scope expansion, and unsupported quality adjectives. It does not read the personal correction corpus or run the optional Router.

The host-neutral workflow is: retrieve attributed context, check its scope, perform the task, then optionally check the output with gate --json or check_draft. A clean gate result is not evidence of successful lesson transfer.

When to invoke it

Run hermeneutic gate on any assistant draft before you send it to the user when:

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.
