run-shelf: Instructions file for Codex

AGENTS.md

run-shelf AGENTS.md is an instructions file for Codex, OpenCode from RuochenLyu/run-shelf. It costs 206 tokens per session, scanned A, original, MIT.

A set of development rules for RunShelf, a macOS tool for running, scheduling, and troubleshooting shell scripts.

In plain words
What is it for?
Use it when changing RunShelf's task storage, locking, scheduling, command-line schemas, Swift files, tests, or release process.
Why use it?
It keeps the app, command-line tool, and scheduler consistent when they share task files, locks, or data formats. It also prevents tests from changing the user's real RunShelf data.

Instructions file for CodexOpenCode

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

This is RuochenLyu/run-shelf's own configuration. It tells Codex and OpenCode how to work on run-shelf 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 run-shelf 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

run-shelf 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.

What it actually says

Run Shelf development contract

  • RunShelf/Core owns the file-native task, run, claim, scheduler, and repository contracts.
  • App views consume TaskStore; they must not coordinate filesystem locks or process claims.
  • CLI, App, and Scheduler use the same task directory and must ship together when lock or schema protocols change.
  • Tests and tools must set RUN_SHELF_APP_SUPPORT_DIR to a temporary directory. Never mutate the user's real Run Shelf data.
  • schemas/*.json are the hand-maintained schema SSOT. Regenerate RunShelf/CLI/GeneratedSchemas.swift with scripts/generate_cli_schemas.rb.
  • Add or move Swift files with bundle exec ruby scripts/sync_xcodeproj_files.rb; do not hand-edit target membership.
  • Run scripts/check.sh before handoff. Commits follow Conventional Commits 1.0.0.
  • Never tag, push, notarize, publish, or read release credentials without explicit operator authorization.

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.
