knowledge-trust-core: Instructions file for Codex

AGENTS.md

knowledge-trust-core AGENTS.md is an instructions file for Codex, OpenCode from haorantang97/knowledge-trust-core. It costs 164 tokens per session, scanned A, original, MIT.

Repository instructions for a read-only trust-policy core: software that evaluates the reliability or maturity of knowledge using evidence. They define boundaries for changing the repository.

In plain words
What is it for?
Use them when modifying this repository to preserve deterministic, explainable verdicts, stable reason codes, synthetic examples, and its read-only scope.
Why use it?
They prevent contributors from adding unrelated capabilities, weakening trust rules, or storing private material. They also require tests and verification before behavior changes.

Instructions file for CodexOpenCode

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

This is haorantang97/knowledge-trust-core's own configuration. It tells Codex and OpenCode how to work on knowledge-trust-core 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 knowledge-trust-core 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

knowledge-trust-core 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.

What it actually says

Agent contribution rules

This repository is a read-only trust-policy core. Preserve that boundary.

  • Add a failing test before every behavior change and run npm run verify before completion.
  • Keep verdicts deterministic, versioned, and explainable with stable reason codes.
  • Do not add numeric truth scores. Maturity is a bounded evidence state, not probability.
  • Do not add storage, retrieval, vector search, approval, Git mutation, database, shell, or network tools to the core or MCP server.
  • Do not silently weaken knowledge-trust-default; weaker variants require a distinct policy ID.
  • Never commit real notes, Raw material, personal paths, credentials, databases, or private source excerpts. Examples must remain synthetic.
  • Adapters may normalize explicit syntax but must not infer missing trust values.
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.
