Requirements

  • Pre-approved tools (allowed-tools): mcp__plugin_ruflo-core_ruflo__browser_open, mcp__plugin_ruflo-core_ruflo__browser_click, mcp__plugin_ruflo-core_ruflo__browser_fill, mcp__plugin_ruflo-core_ruflo__browser_type, mcp__plugin_ruflo-core_ruflo__browser_press, mcp__plugin_ruflo-core_ruflo__browser_check, mcp__plugin_ruflo-core_ruflo__browser_uncheck, mcp__plugin_ruflo-core_ruflo__browser_select, mcp__plugin_ruflo-core_ruflo__browser_hover, mcp__plugin_ruflo-core_ruflo__browser_wait, mcp__plugin_ruflo-core_ruflo__browser_screenshot, mcp__plugin_ruflo-core_ruflo__browser_snapshot, mcp__plugin_ruflo-core_ruflo__browser_get-text, mcp__plugin_ruflo-core_ruflo__browser_get-title, mcp__plugin_ruflo-core_ruflo__browser_get-url, mcp__plugin_ruflo-core_ruflo__browser_get-value, mcp__plugin_ruflo-core_ruflo__browser_eval, mcp__plugin_ruflo-core_ruflo__browser_close, mcp__plugin_ruflo-core_ruflo__browser_session-list, mcp__plugin_ruflo-core_ruflo__aidefence_is_safe, Bash, Read, Write

Workflow steps

8 steps, taken from the first numbered list in SKILL.md.

  1. Record the test run by composing browser-record
  2. Drive interactions — browser_open, browser_click, browser_fill, browser_type, browser_select. Each action emits a trajectory-step.
  3. Wait for elements / network idle via browser_wait before assertions.
  4. Validate with browser_get-text / browser_get-value / browser_get-title / browser_get-url. Validation outcomes go into findings.md inside…
  5. Screenshot before / after key interactions for visual regression. Filenames follow .png.
  6. Snapshot the accessibility tree at navigation boundaries.
  7. End the session: trajectory-end --verdict pass|fail, rvf compact, AgentDB index in browser-sessions.
  8. (Optional) Diff against --against : invoke browser-screenshot-diff to compare the new run with a baseline.

What it can do on your machine

Read from SKILL.md and the folder at commit de590e1. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • mcp__plugin_ruflo-core_ruflo__browser_open
    • mcp__plugin_ruflo-core_ruflo__browser_click
    • mcp__plugin_ruflo-core_ruflo__browser_fill
    • mcp__plugin_ruflo-core_ruflo__browser_type
    • mcp__plugin_ruflo-core_ruflo__browser_press
    • mcp__plugin_ruflo-core_ruflo__browser_check
    • mcp__plugin_ruflo-core_ruflo__browser_uncheck
    • mcp__plugin_ruflo-core_ruflo__browser_select
    • mcp__plugin_ruflo-core_ruflo__browser_hover
    • mcp__plugin_ruflo-core_ruflo__browser_wait

    …and 13 more on the same allowed-tools line.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Browser Test loads about 899 tokens when it runs. Until then it costs about 40 tokens; SKILL.md has 300 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~40
When it runs · the whole SKILL.md, loaded when a task matches
~899

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    allowed-tools: mcp__plugin_ruflo-core_ruflo__browser_open, mcp__plugin_ruflo-core_ruflo__browser_click, mcp__plugin

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Browser Test

Automated UI testing. Now backed by a recorded RVF session container instead of an ephemeral run, so every test produces a replayable artifact.

When to use

  • Verifying UI functionality, user flows, or that frontend changes work in a real browser.
  • Producing a baseline session that future regressions can diff against.
  • Re-running a stored test session when CI fails (no need to re-author the test).

Steps

  1. Record the test run by composing browser-record:
    • Allocates an RVF container with --kind browser-session.
    • Begins a ruvector trajectory.
  2. Drive interactions — browser_open, browser_click, browser_fill, browser_type, browser_select. Each action emits a trajectory-step.
  3. Wait for elements / network idle via browser_wait before assertions.
  4. Validate with browser_get-text / browser_get-value / browser_get-title / browser_get-url. Validation outcomes go into findings.md inside the RVF container.
  5. Screenshot before / after key interactions for visual regression. Filenames follow <step-id>.png.
  6. Snapshot the accessibility tree at navigation boundaries.
  7. End the session: trajectory-end --verdict pass|fail, rvf compact, AgentDB index in browser-sessions.
  8. (Optional) Diff against --against <prior-session-id>: invoke browser-screenshot-diff to compare the new run with a baseline.

Navigation

  • browser_back / browser_forward for history navigation
  • browser_reload to refresh the page
  • browser_scroll to scroll to elements or coordinates

What changed from v0.1.0

  • The skill no longer ends with browser_close alone — it ends with the session-end protocol.
  • Selectors discovered during the test land in browser-selectors (host:intent), so the next test can find them by embedding similarity.
  • Validation outputs pass aidefence_is_safe before any LLM-facing summary; injection-flagged content is quarantined to findings.md.
  • The same skill, used in CI, now produces an artifact that /ruflo-browser replay can re-drive.

Tips

  • Use browser_wait before assertions to handle async rendering.
  • For visual regression, save the parent session id and pass --against <id> on the next run.
  • Use browser_eval for custom JavaScript assertions — but redact any returned strings via the aidefence_is_safe gate before logging.
