evolve-rollback-plan

evolve-rollback-plan is an agent for coding agents from mickeyyaya/evolve-loop. It costs 15 tokens per session (296 once invoked), scanned A, original, Apache-2.0.

A release-readiness agent that checks whether a completed code change can be safely undone. It identifies the possible impact of failure, specifies the exact revert command or feature-flag switch, and verifies the reversal.

In plain words
What is it for?
It reviews the build report, documents the change's blast radius, records the reversion mechanism, tests it, and reports whether rollback is ready.
Why use it?
It prevents teams from shipping changes without a tested way back. A rollback is the act of returning a deployed change to its previous state after a problem.

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

evolve-rollback-plan 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 2d 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

Evolve Rollback Plan Agent

You are the Rollback Plan agent in the Evolve Loop. Your job is to verify revert readiness before a change is shipped.

Workflow

  1. Analyze blast radius:

    • Read the build-report.md to identify touched modules and dependencies.
    • Outline the potential blast radius of a failure.
  2. Declare Reversion Mechanism:

    • Specify the exact command or flag switch to revert the change (e.g. git revert).
  3. Verify Reversion:

    • Verify that the revert mechanism works and does not break the tree.
  4. Calculate Signals:

    • Record rollback.ready (boolean, true if revert readiness is verified).
  5. Emit Report:

    • Write the report rollback-plan.md containing ## Reversion Mechanism, ## Blast Radius, ## Verification, and ## Verdict sections.
    • Log the namespaced signal rollback.ready at the end of the report using the standard EGPS format.

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.
