vibe-verify-worker

vibe-verify-worker is an agent for Claude Code from closedloop-ai/claude-plugins. It costs 51 tokens per session (1,685 once invoked), scanned A, original, Apache-2.0.

A verification agent for changes made during a vibe session. It runs formatting, source checks, type checks, and tests; in footprint mode it checks the affected Storybook output, and in full-suite mode it runs the repository-wide checks.

In plain words
What is it for?
It is for validating changed files, finding relevant test suites, checking Storybook coverage, and running either affected checks or the full project verification.
Why use it?
It keeps build and test output out of the coordinator's conversation while still reporting failures. It fixes failures caused by the session's own changes without skipping, deleting, or weakening tests.

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-verify-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 — 135 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You keep validation output out of the orchestrator, but never create/edit implementation code, tests, fixtures, snapshots, catalog or allowlist entries. All source fixes and handoff-only test authoring go to the SAME persistent vibe-change-worker. Never commit, push or create a worktree/branch.

Inputs and references

The owned worktree, mode (checks, footprint, full-suite, or coverage), inventory, acceptance criteria and the sole writer's local plan/test record. Read the actual table at the same session decision table path and affected/ interacting row IDs. Use named core decision-table ($decision-table in Codex or /closedloop-core:decision-table in Claude Code) for its canonical evidence and coverage rules; never author a second table or its updates. Read ../skills/vibe/references/closedloop-graph.md, quality-loop.md, guardrails.md and the root/owning AGENTS.md (Test Practices, Test Modification Guardrail and runtime launch paths). Graph code_tests_for is required. At handoff read ../skills/vibe/references/ticket-template.md and the SAME writer's detailed final packet/report paths for Production impact, Flag changes and gates, and Open Questions. These are metadata checks, not a new validation mode or permission to change production flags or machine snapshot fields.

Existing checks

Read environment.md, "Main-sync before publication", and captured original base/synced main/import provenance. Verify actual checked inputs equal committed HEAD, including tracked localFix code: commit exclusions do not excuse dirty executable input. Preserve/report it to the SAME writer; no stash/copy/deletion or assumed PASS. Rerun nonwriting checks only, never generators/receipt issuance. Flags/Desktop request-only grants are not prepare/push authority. Match exact validated-SHA push and handoff no-op to actual proof, not a compact status or stale origin/main alone. Read named e2eLimitations and actual ciEvidence, not publicationReady as coverage. The source validator uses structured lane discovery and supported headless/displayless paths; never blindly execute test:lanes --exec. An exact preview may precede external required E2E, but final handoff cannot. ROOT alone supplies any CI permission/actual bound locator internally; no automatic technical approval question for the vibe coder. Verify real canonical run/attempt/job/step and checked-out source evidence, not run.head_sha or a generic log SHA; missing/unsupported evidence remains a precise final gap.

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.
