DevHotel: Instructions file for Codex

AGENTS.md

DevHotel AGENTS.md is an instructions file for Codex, OpenCode from r2cuerdame/DevHotel. It costs 315 tokens per session, scanned A, original, MIT.

Repository instructions for working on DevHotel, including how to use project records, GitHub issues and pull requests, and deployment boundaries. They also define validation and rules against unsafe or costly operations.

In plain words
What is it for?
Use them to decide which work is approved, record implementation plans, preserve the canonical checkout, and run the permitted validation commands.
Why use it?
They prevent agents from overwriting existing work, bypassing review, deploying accidentally, or creating unapproved cloud costs.

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

This is r2cuerdame/DevHotel's own configuration. It tells Codex and OpenCode how to work on DevHotel 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 DevHotel 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

DevHotel 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 today.

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

LoopOffice PD / Worker contract

Read .loop/project.md before work. One PD owns this project and uses the existing canonical checkout. Preserve dirty files and branch drift; do not reset, force push, clone, create worktrees, or bypass hooks/protection.

Use GitHub issues, PRs and milestones as the ledger and execute only latest plan-audited work. Bugs, stability, milestones and owner work can run after that audit. New features/product direction require needsApproval: true, reason: direction. Create one canonical PLC plan when absent and avoid duplicate PLC/research issues. Historical Growth KPI issues are not implementation work.

Cost and deployment boundary

deployWorkflow: not_required: do not run release.yml, android-emulator-preview-image.yml, production deploy/release/image publication workflows, tag or publish releases. Never create/change/scale AWS or other paid infrastructure or add paid API spend. New costs require needsApproval: true, reason: cost and owner approval. Existing subscription AI must use the shared resource manager routing and limits; do not fix providers/models or downgrade tiers.

Validation

Free isolated validation: pnpm lint, pnpm typecheck, pnpm test, pnpm --filter devhotel-mcp build; Windows CI job build additionally packages with --publish never. Run builds/tests through CSX observation. Respect host input isolation and Room boundaries; do not change host sessions, VM/Docker setup or infrastructure to bypass unavailable environments. Record those limitations. Never print secrets.

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.
