vindicate

A guided workflow for creating and maintaining Playwright browser tests; Playwright is a tool that controls a web browser for automated checks.

In plain words
What is it for?
Writing, fixing, stabilizing, refactoring, running, or auditing Playwright tests, finding coverage gaps, and setting up projects or continuous integration.
Why use it?
It gives browser-testing tasks a defined path, helping keep tests grounded in the application and the requested work.

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

vindicate 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.

Vindicate — Playwright Test Automation

You produce grounded, conformant Playwright tests through Vindicate's workflow. Engage this whenever the user wants to write / add / fix / stabilize / refactor / run / audit tests, find coverage gaps, or set up Playwright automation or CI. For general coding, docs, or questions, work directly — don't use Vindicate tools.

Start every task by orienting

  1. Call vindicate_workflow() (no args) → map + empty progress panel. Pick the entry path:

    • write / add tests → write
    • fix a specific broken test → fix
    • stabilize a flaky / intermittent test → flaky
    • refactor tests (no behavior change) → refactor
    • find missing coverage by exploring the app → gaps
    • report AC coverage from stories vs specs (no exploration) → coverage
    • run existing tests against a URL → smoke
    • draft requirements/a story only from a recording (no tests) → requirements
    • scaffold a project from scratch → bootstrap
    • add or fix Playwright CI → ci

    If the task is genuinely ambiguous, ask the user which path (one question).

  2. Start the path: vindicate_workflow(path="write", node="understand", completed=[]) (swap path/node for your task).

  3. Each phase change: when the current node done-conditions are met, call the next node with completed updated — add the node you just finished:

    vindicate_workflow(path="write", node="ground", from="understand", completed=["understand"])
    

    Always copy progress_echo from the last response into the next call (path, node, completed).

  4. Read phase_instructions in each tool result — mandatory phase steps at the top; workflow-tool field rules in the appended section. Follow progress_display.instruction exactly (server detects whether this client renders the MCP App panel). Use agent_directives for progress_echo, done-conditions, and the next call.

  5. Branches are allowed (e.g. execute → heal → ground) — update node, from, and completed to match where you are; the panel shows heal when you enter it.

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

vindicate is a skill published in the GitHub repository OpenEvident/vindicate (46 stars, last pushed 2d ago), licensed Apache-2.0. It adds 77 tokens to every session and 1,150 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
