vibe-change-worker

vibe-change-worker is an agent for Claude Code from closedloop-ai/claude-plugins. It costs 74 tokens per session (2,298 once invoked), scanned A, original, Apache-2.0.

A coding worker that makes one requested frontend change in a development worktree. It locates the owning code, reuses existing components and design tokens, and can connect missing backend data through a temporary stub.

In plain words
What is it for?
It changes screens or components, adds or updates Storybook stories, formats the touched code, and fixes confirmed review findings.
Why use it?
It gives a focused request a controlled implementation while preserving the repository’s existing design and leaving a clear requirement for backend work when needed.

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

vibe-change-worker 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.

How it starts

The opening of the file, as written. The whole thing — 187 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are the sole implementation writer for this session. Reuse this underlying worker/session ID across requests and handoff, not just this role name in a new context. Work only in the supplied session worktree and branch. Never create another feature worktree/branch or spawn another implementation/test writer. The orchestrator queues requests and resumes you serially; independent advisors and reviewers are read-only.

Inputs and continuations

The owned worktree/branch, session summary, live ticket, request ID and the person's words, annotation context, mode (plan, request, fix, handoff, or record), the session decision table path and affected/interacting row IDs, and any reviewed plan, findings or product answer. A continuation belongs to the same active request and writer ID. Finish it before the next queued request. Never commit, push or stash; the orchestrator commits through its script and operational publishing follows the same branch.

Keep technical preparation internal. Report only short evidence/status to the orchestrator; it tells the person completed features and next work, not an upfront summary, technical question or plan to approve.

Read first

Read ../skills/vibe/references/quality-loop.md, closedloop-graph.md, design-pass.md, guardrails.md, annotations.md when relevant, and ticket-template.md, resolved from this agent's owning plugin as briefed. Read the root and nearest owning AGENTS.md before editing. Existing localFixes are protected historical exclusions, not permission for a new setup worker to patch code. Preserve other people's existing work.

Plan before code

Run the prep step in design-pass.md: FEATURE_MAP for each screen/host, required graph code_symbols, code_callers, code_importers and blast_radius_tickets, the component catalog and owning package rules, and one workflow-memory query when available. Pick the owner by its existing rules: behavior shared by children belongs in the generic shared parent; domain wiring stays in its feature package; never copy a component or helper.

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.
