Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions Claude Code; mentions AGENTS.md; mentions Codex.

This is eXPerience83/remote-dev-containers's own configuration. It tells Codex and OpenCode how to work on remote-dev-containers itself, so it is not a mod to install elsewhere.

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

remote-dev-containers 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 yesterday.

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 — 174 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

These instructions apply to the entire repository unless a more specific nested AGENTS.md is added later.

Sources of truth

Before changing runtime architecture or support claims, read the current code and owning GitHub issues rather than relying on stale prose.

Current high-level ownership:

  • #31 is the experimental-release/support tracker and should list only genuinely remaining release blockers.
  • #24/#25 are completed single-image, single-stack, isolated-service/role-neutral runtime foundations.
  • #36 records the completed TrueNAS outer-isolation and no-system-Bubblewrap decision.
  • #42 records completed outer-container hardening and cross-service canaries.
  • #53 is the standing third-party/license/vendor-policy review log. Automation provides evidence, never legal approval.
  • #69 is the completed browser-authentication decision: one configuration-backed WEB_PASSWORD runtime contract for protected agent endpoints; the former file-backed browser-password path is retired.
  • #70/#167 define the canonical persistent-data layout and deterministic TrueNAS bootstrap/preflight.
  • #186 defines the completed TrueNAS Generic/POSIX private-state ACL audit/migration contract.
  • #92 owns broad English/Spanish documentation and implementation-status synchronization.
  • #96 owns the completed Antigravity reviewed/review-pending/damaged runtime-admission model.
  • #83 owns the shipped Antigravity scheduled static discovery plus explicit executable-review automation; it must not gate or revoke an intact admitted runtime merely because review state changes.
  • #103 owns optional explicit Codex runtime updates while preserving the immutable bundled fallback.
  • #120 owns the permanent dev -> edge -> stable = latest channel contract.
  • #168 owns dated edge build identity and grouped-upstream changelog provenance.
  • #189 owns the completed Renovate Ubuntu runtime-image changelog provenance boundary.

If issue prose and repository code disagree, resolve the discrepancy explicitly before broadening scope.

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.
