invara: Instructions file for Codex

AGENTS.md

invara AGENTS.md is an instructions file for Codex, OpenCode from Jujitae/invara. It costs 585 tokens per session, scanned A, original, Apache-2.0.

A project instruction guide for working on the Invara codebase. It explains the product’s boundaries, architecture, trusted sources, rules, commands, and completion checks.

In plain words
What is it for?
Use it to understand the repository, follow its safety and evidence rules, run the right checks, and decide when a change is actually finished.
Why use it?
It gives coding agents a shared set of rules and prevents them from treating unverified claims as proof that work is complete.

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

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

invara 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.

INVARA local execution handbook

Product boundary

INVARA independently evaluates declared constraints from observable file bytes, command results, and recorded provenance. It does not prove general software correctness, authorize work, or accept an agent's claim that work is done. BLOCK and UNVERIFIABLE are valid fail-closed outcomes, not conditions to weaken away.

Local architecture and canonical sources

  • src/invara/: contract sealing, observation, verdict, replay, and hash-chain implementation.
  • tests/test_invara.py: refusal-first executable specification.
  • README.md: user-facing product contract and first-verdict flow.
  • PROVENANCE.md, PRIVACY.md, and SECURITY.md: provenance, local-only data, and threat-model commitments.
  • plugin/: bundled MCP/stdio surface; its Python package and license files must stay byte-aligned with src/invara/ and the root license files.
  • Company orchestration, portfolio priority, role routing, and main integration authority live in migaryos-hq; this repository does not restate them.

Invariants and known traps

  • Observable evidence and deterministic verdicts are authoritative; self-report is not completion evidence. An agent may request a verdict but cannot give itself one.
  • Preserve sealed-contract, protected-path, evidence, hash-chain, and replay semantics. Do not turn a refusal, broken check, or missing executable into green; retain fail-closed UNVERIFIABLE/BLOCK behavior.
  • The buyer is a non-coder: the MCP/stdio entry point and usable first-verdict experience are product surfaces, not optional demos.
  • Keep the zero-runtime-dependency and local-only/no-outbound-network claims true: the only sockets are the loopback ones the assurance executor opens to a service the manifest itself starts; nothing may call out. Contracts run user-named commands with user permissions and can store their command strings; never put secrets in a contract.
  • Windows encoding, Store Python aliases, CRLF digest changes, and plugin-copy drift are tested product behavior. Do not paper over them with platform- specific bypasses.

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.
