AGENTS.md

NavoCMS AGENTS.md is an instructions file for Codex, OpenCode from Tsumibito/NavoCMS. It costs 392 tokens per session, scanned A, original, Apache-2.0.

Repository instructions for NavoCMS, a content-management system operated primarily through an authenticated agent.

In plain words
What is it for?
Use them when modifying NavoCMS code, especially work involving permissions, tenant isolation, releases, migrations, plugins, or managed content.
Why use it?
They define security, publishing, content, multitenancy, and development rules so changes preserve the system's required behavior.

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

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

NavoCMS 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 8d 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.

How it starts

The opening of the file, as written. The whole thing — 38 lines — stays where its author put it; the contents beside it link to each section on GitHub.

These rules apply to every automated agent and human contributor in this repository.

Product invariants

  • The primary operator interface is an authenticated MCP agent. Focused UI is optional and cannot become the only way to complete a core workflow.
  • Keep the trusted kernel small. Identity, tenant isolation, authorization, event integrity, idempotency, migrations, secrets, quotas, and release policy are not ordinary plugins.
  • Plugins request versioned capabilities. They never expand the authority of their caller.
  • Every consequential action emits an auditable domain event. Never log hidden model reasoning, credentials, unrestricted PII, or full lead/customer payloads.
  • Public publication uses immutable revisions and releases. Approval binds to the exact previewed release hash; stale approval fails closed.
  • Canonical prose is portable Markdown plus schema-validated directives. Do not introduce Lexical, arbitrary MDX, or executable HTML as managed content formats.
  • Multitenancy is foundational. Every site-owned resource must be tenant- and site-scoped, with database isolation tested independently from application filtering.
  • Runtime installation of unreviewed plugin packages by an agent is prohibited.

Contract changes

  • Changes to schemas/ require matching specification updates, fixtures, validation tests, and a compatibility note.
  • Breaking contract changes require a new version; never silently alter an already released schema.
  • Architecture changes require an ADR in docs/architecture/.
  • Update roadmap gates only when their verification criteria have actually passed.

Working practices

  • Prefer small pull requests with one reviewable architectural outcome.
  • Preserve unrelated work and never commit secrets, decrypted dotenv files, customer content, or production exports.
  • Pin dependencies and GitHub Actions deliberately. Minimize new runtime dependencies.
  • Run pnpm check before proposing a change.
  • Treat examples as executable contract fixtures, not illustrative pseudocode.

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.
