proofpress: Instructions file for Codex

AGENTS.md

proofpress AGENTS.md is an instructions file for Codex, OpenCode from chenmingtang830/proofpress. It costs 6,095 tokens per session, scanned A, original, Apache-2.0.

A set of project instructions for Proofpress, a tool that tracks revisions to Markdown and static HTML knowledge files in a ledger.

In plain words
What is it for?
Use it when editing tracked Markdown or static HTML knowledge artifacts, including capturing prior versions, preserving block identifiers, checking policy, and writing claims records.
Why use it?
It helps preserve human edits, keep files portable, and record exactly which documented claims changed. It prevents agents from treating every conversation as a versioned revision.

Instructions file for CodexOpenCode

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

This is chenmingtang830/proofpress's own configuration. It tells Codex and OpenCode how to work on proofpress 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 proofpress 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

proofpress 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 2mo 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.

Project instructions

Default: hosted governed context

For durable agent-produced knowledge, use the proofpress-governed-context skill. It is the default governance path for this repository; Markdown, HTML, and source-code changes do not require artifact-ledger capture or snapshotting.

When operating from another repository, install this repository's proofpress-governed-context skill before connecting MCP. Use the client-specific installation commands in docs/REMOTE_MCP.md. MCP supplies the tool surface, while the skill supplies the required governance workflow.

Before relying on prior knowledge, retrieve only eligible, in-scope governed context and preserve its limits. For a durable decision, evidence-backed claim, reproducible experiment result, integration contract, or incident learning, submit a bounded proposal with evidence and report its receipt.

An agent may propose and evaluate but may never approve its own proposal, use owner or recovery credentials, upload secrets or raw private traces, or claim that a candidate is governed context before authorized human approval.

Optional: portable artifact ledger

Use proofpress legacy only when the user explicitly asks for a portable, offline-verifiable artifact history or when receiving a portable artifact for inspection or import. Existing artifact histories, anchors, and capsules are preserved; do not remove or rewrite them merely because this is no longer the default workflow.

For an explicitly selected portable artifact, run capture before editing an existing target; then read its policy, preserve native anchors, write honest claims for touched blocks, snapshot with explicit actors and a real reason, and run verify. Do not use the legacy ledger for source code, routine documents, or the governed-context skill.

Changes

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.
