agent-rollback AGENTS.md

agent-rollback AGENTS.md is an instructions file for Codex, OpenCode from Nainish-Rai/agent-rollback. It costs 219 tokens per session, scanned A, original, MIT.

Project instructions for agent-rollback, a Node.js command-line tool that creates checkpoints of workspace files and can compare or restore them. A checkpoint is a saved state that can be used to undo later changes.

In plain words
What is it for?
Use them when changing checkpoint creation, file discovery, change comparison, restoration, command execution, or the related tests.
Why use it?
They define the file responsibilities and safety rules needed to preserve reliable snapshots and avoid unsafe workspace operations.

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

agent-rollback 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 5d 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

Agent Instructions

Project Shape

  • bin/agent-rollback.js is the executable entry point.
  • src/cli.js owns command parsing and user-facing output.
  • src/snapshot.js owns checkpoint creation, diffing, listing, and restore.
  • src/workspace.js owns workspace file discovery and path safety.
  • src/runner.js owns the codex exec wrapper behavior.
  • test/*.test.js uses Node's built-in test runner.

Commands

Run before committing:

npm test
npm run check

Engineering Rules

  • Keep runtime dependencies at zero unless a dependency clearly removes more risk than it adds.
  • Prefer small, focused functions with clear names.
  • Do not add undocumented Codex hook assumptions without linking to official OpenAI docs or a stable upstream source.
  • Storage changes need integration tests that create, mutate, diff, and restore a temporary workspace.
  • Preserve content-addressed object storage unless replacing it with a simpler tested design.
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.
