nymrel-agent AGENTS.md

nymrel-agent AGENTS.md is an instructions file for Codex, OpenCode from nymrel/nymrel-agent. It costs 490 tokens per session, scanned A, original, MIT.

Repository instructions defining how the Nymrel Agent project may be developed, released, and deployed. They describe its routing service, allowed changes, required checks, and security boundaries.

In plain words
What is it for?
Use them when working on routing, provider adapters, tests, documentation, CLI or MCP code, packaging, releases, or deployment for this project.
Why use it?
They prevent work from proceeding with the wrong release source or with exposed provider credentials and other prohibited data. They also make required validation clear before release work.

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

nymrel-agent 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 4d 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.

Nymrel Agent production operating boundary

This repository is the Nymrel-owned composition root for the Nymrel Agent product and implementation service. The public product is a stateless multi-model router; optional provider execution is customer-local and read-only in v0.1.

Allowed work

  • Provider-neutral routing contracts, deterministic scoring, validation, receipts, tests, documentation, CLI, MCP, and the public routing Worker.
  • Read-only local provider adapters that obtain credentials from environment-variable names in customer-owned configuration.
  • Release packaging, public source publication, and deployment through the recorded production launch packet.

Five-minute release orientation

Before any release, deployment, or public-claim work, read docs/ONBOARDING.md and run its fail-before-work origin check. The only authoritative remote is https://github.com/Nymrel/nymrel-agent.git; legacy-jalenbuildshub is a retained historical reference and is never a release or deployment authority. Do not continue if the check fails.

Non-negotiable boundaries

  • Never commit, print, transmit to the public router, or place in receipts any provider credential, prompt, task body, output body, customer data, or private studio artifact.
  • The public API accepts routing metadata only and performs no model execution.
  • Local execution remains read-only in v0.1. Do not add shell, filesystem-write, browser-mutation, outreach, purchase, deployment, or other side-effect tools without a separate isolation and authorization decision.
  • Do not add hosted credential custody, accounts, billing, customer-data persistence, or model brokering without a separate protected-gate decision.
  • Pi, OMP, and other runtimes may be optional subordinate adapters only; they do not replace the Nymrel-owned contract, router, policy, receipts, or release authority.
  • Model scores and profile facts are caller-supplied evidence. Do not present them as Nymrel benchmarks or universal truth.

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.
