rollback

A command for moving a V-Bounce software development workflow back to an earlier phase and resetting the later phases.

In plain words
What is it for?
Use it to roll back a workflow, clear the status of later phases, and record the rollback in the cycle history.
Why use it?
It gives the team a way to revisit requirements, design, contracts, implementation, or review when earlier work needs changing.

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

rollback 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.

What it actually says

Rollback to a previous phase in the current V-Bounce cycle. User must provide the target phase name.

Instructions

  1. Read .vbounce/state.yaml to get the active workspace
  2. Read {workspace}/state.yaml to get the current phase
  3. Valid target phases: requirements, design, contracts, implementation, review
  4. Validate: target phase must be BEFORE current phase in the sequence
  5. Reset the target phase status to not_started
  6. Reset all phases AFTER the target to not_started
  7. Update state: current_phase: {target}, anatomy_step: input
  8. Add history entry with timestamp and reason
  9. Report: "Rolled back to {target}. Phases after {target} have been reset."
  10. Do NOT dispatch any agents — only update state
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.
