What it does

Skyvern Browser Automation is an agent skill from sickn33/agentic-awesome-skills. AI-powered browser automation — navigate sites, fill forms, extract structured data, log in with stored credentials, and build reusable workflows.

Its SKILL.md is about 3.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Productivity & Automation, covering Browser automation, Forms and invoices and CI/CD. The repository describes itself as: AAS Core is the local, agent-first control plane for complete catalog discovery, agent-owned selection, stack validation, and planning, backed by 2,400+ agentic skills. Includes… The licence is AGPL-3.0.

When your agent uses it

  • Tasks that involve Browser automation
  • Tasks that involve Forms and invoices
  • Tasks that involve CI/CD

Example prompts

  • “/skyvern-browser-automation”

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Classify Your Task (ALWAYS do this first)
  2. Apply These Decision Rules
  3. Create a Session
  4. Execute by Classification
  5. Verify
  6. Error Recovery

What it can do on your machine

Read from SKILL.md and the folder at commit b84d35a. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).

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

  • Network

    Links to these hosts (documentation or services it may open):

    • github.com

    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

Skyvern Browser Automation loads about 3.5k tokens when it runs. Until then it costs about 43 tokens; SKILL.md has 1,034 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~43
When it runs · the whole SKILL.md, loaded when a task matches
~3.5k

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 passed

The automated check found no risky patterns in SKILL.md.

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.

Skyvern Browser Automation -- CLI Judgment Procedure

Skyvern uses AI to navigate and interact with websites. Every command below is a runnable skyvern <command> invocation.

When to Use This Skill

  • Use when you need AI-assisted browser automation for navigation, extraction, form filling, login flows, or reusable website workflows.
  • Use when deterministic selectors are unavailable and Skyvern's visual/a11y reasoning can identify page controls.
  • Use when a one-off browser task should become a repeatable workflow with run history and verification.

Step 1: Classify Your Task (ALWAYS do this first)

ClassificationSignalCLI CommandCostWhat Happens
Quick check (yes/no)"is the user logged in?"skyvern browser validate1 LLM + screenshotsLightweight validation (2 steps max), returns boolean. Cheapest AI option.
Quick inspection"what does the page show?"skyvern browser extract1 LLM + screenshotsDedicated extraction LLM + schema validation + caching.
Single action (known target)"click #submit"skyvern browser click/type0 LLMDeterministic Playwright. No AI. Fastest.
Single action (unknown target)"click the submit button"skyvern browser act2-3 LLM, no screenshotsNo screenshots in reasoning. Economy a11y tree. For visual targets, use hybrid mode (selector + intent).
Same-page multi-step"fill the form and submit"skyvern browser act or primitive chain2-3 LLM or 0 LLMUse act when labels are clear. Use click/type/select directly when you know selectors.
Throwaway autonomous trial"try this once", "see if this works"skyvern browser run-taskHigherOne-off autonomous agent for exploration. Do not use for recurring or multi-page production automations.
Multi-page or reusable automation"navigate a multi-page wizard", "set this up", "automate this weekly"skyvern workflow create + runN LLM + screenshotsBuild a workflow with one block per step. Each block gets visual reasoning, verification, and reusable run history.

MCP note: if you are using the Skyvern MCP instead of the CLI, prefer observe + execute for same-page multi-step UI work. The CLI does not expose that pair directly.

Step 2: Apply These Decision Rules

  1. If the prompt includes a selector, id, XPath, or exact field target, use browser primitives -- not act.
  2. If you only need a yes/no answer, use validate -- not extract or act.
  3. If the work stays on one page and labels are clear, use act or a primitive chain.
  4. If the user says try this once, see if this works, or clearly wants a one-off exploratory trial, use run-task.
  5. If the task spans multiple pages and is meant to be reusable, scheduled, repeatable, or explicitly set up as automation, use workflow create.
  6. Never type passwords. Always use stored credentials with skyvern browser login.

Step 3: Create a Session

Every browser command needs a session. Create one first:

bash
# Cloud session (default -- works for public URLs)
skyvern browser session create --timeout 30

# Local session (for localhost URLs or self-hosted mode)
skyvern browser session create --local --timeout 30

# Connect to existing browser via CDP
skyvern browser session connect --cdp "ws://localhost:9222"

Session state persists between commands. After session create, subsequent commands auto-attach. Override with --session pbs_.... Close when done: skyvern browser session close.

Step 4: Execute by Classification

Quick check (yes/no)
bash
skyvern browser validate --prompt "Is the user logged in? Look for a dashboard or avatar."

Returns true/false. Cheapest AI option -- prefer over extract or act for boolean checks.

Quick inspection
bash
skyvern browser extract \
  --prompt "Extract all product names and prices" \
  --schema '{"type":"object","properties":{"items":{"type":"array","items":{"type":"object","properties":{"name":{"type":"string"},"price":{"type":"string"}}}}}}'

Uses screenshots + dedicated extraction LLM. Better than screenshot+read because Skyvern's LLM interprets the page.

Single action (known target)
bash
skyvern browser click --selector "#submit-btn"
skyvern browser type --text "user@co.com" --selector "#email"
skyvern browser select --value "US" --intent "the country dropdown"

Deterministic. No AI. Three targeting modes:

  1. Intent: --intent "the Submit button" (AI finds element)
  2. Selector: --selector "#submit-btn" (CSS/XPath, deterministic)
  3. Hybrid: both (selector narrows, AI confirms)
Single action (unknown target)
bash
skyvern browser act --prompt "Click the Sign In button"
skyvern browser act --prompt "Close the cookie banner, then click Sign In"

Warning: act has NO screenshots in its LLM reasoning. It uses an economy accessibility tree. Fine for well-labeled elements. For visually complex targets, use MCP observe+click or hybrid mode.

Same-page multi-step
bash
skyvern browser act --prompt "Fill the shipping form and click Continue"

Use act when the fields and buttons are clearly labeled and the flow stays on one page. If you need tighter control, break the work into click, type, select, press-key, and wait.

Throwaway autonomous trial
bash
skyvern browser run-task \
  --url "https://example.com" \
  --prompt "Check whether the checkout flow works end to end and extract the confirmation number"

Use run-task to prove feasibility or do one-off exploration. If the task becomes important enough to rerun, debug, or share, convert it to a workflow.

Multi-page or reusable automation — build a workflow with one block per step
bash
skyvern workflow create --definition @checkout-workflow.yaml
skyvern workflow run --id wpid_123 --wait
skyvern workflow status --run-id wr_789

Each navigation block runs with visual reasoning + verification. Split complex flows into multiple blocks (one per page/step). First run uses AI; subsequent runs replay cached scripts.

Repeated/production
bash
skyvern workflow create --definition @workflow.yaml
skyvern workflow run --id wpid_123 --params '{"email":"user@co.com"}'
skyvern workflow status --run-id wr_789

Split into one block per step. Use navigation blocks for actions, extraction for data. First run uses AI; subsequent runs replay a cached script (10-100x faster). Set --run-with agent to force AI mode for debugging.

Step 5: Verify

Always verify after page-changing actions:

bash
skyvern browser screenshot                          # visual check
skyvern browser validate --prompt "Was the form submitted successfully?"  # boolean assertion
skyvern browser evaluate --expression "document.title"                    # JS state check

Step 6: Error Recovery

ProblemFix
Action clicked wrong elementAdd context to prompt. Use hybrid mode (selector + intent).
Extraction returns emptyWait for content. Relax required fields. Check row count first.
Login passes but next step failsEnsure same session. Add post-login validate check.
Element not foundAdd wait: skyvern browser wait --selector "#el" --state visible
Overloaded promptSplit into smaller goals -- one intent per command.

Credentials

NEVER type passwords through skyvern browser type or act. Always use stored credentials:

bash
skyvern credentials add --name "my-login" --type password --username "user@co.com"
skyvern credential list                          # find the credential ID
skyvern browser login --url "https://login.example.com" --credential-id cred_123

Types: password, credit_card, secret. Also supports bitwarden, 1password, and azure_vault providers.

Workflow Quick Reference

bash
skyvern workflow create --definition @workflow.yaml   # create
skyvern workflow run --id wpid_123 --wait             # run and wait
skyvern workflow status --run-id wr_789               # check status
skyvern workflow list --search "invoice"              # find workflows
skyvern block schema --type navigation                # discover block types
skyvern block validate --block-json @block.json       # validate before creating

Engine: known path = 1.0 (default). Dynamic planning = 2.0. Split into multiple 1.0 blocks when in doubt. Status lifecycle: created -> queued -> running -> completed | failed | canceled | terminated | timed_out

Common Patterns

Login flow:

bash
skyvern credential list                          # find credential ID
skyvern browser session create
skyvern browser navigate --url "https://login.example.com"
skyvern browser login --url "https://login.example.com" --credential-id cred_123
skyvern browser validate --prompt "Is the user logged in?"
skyvern browser screenshot

Pagination loop:

bash
skyvern browser extract --prompt "Extract all rows"
skyvern browser validate --prompt "Is there a Next button that is not disabled?"
# If true:
skyvern browser act --prompt "Click the Next page button"
# Repeat extraction. Stop when: no next button, duplicate first row, or max page limit.

Debugging:

bash
skyvern browser screenshot                       # visual state
skyvern browser evaluate --expression "document.title"
skyvern browser evaluate --expression "document.querySelectorAll('table tr').length"

Limitations

  • Do not use Skyvern to bypass site access controls, rate limits, consent gates, or terms that prohibit automation.
  • Browser automation can change remote state; confirm user intent before submitting forms, purchasing, deleting, or sending messages.
  • Prefer deterministic selectors for stable production flows; AI actions can misread unlabeled or visually ambiguous controls.
  • Store credentials only in the supported credential vaults and never type passwords directly through type or act.

Agent Mode

All commands accept --json for structured output. Set SKYVERN_NON_INTERACTIVE=1 to prevent prompts. Use skyvern capabilities --json for full command discovery. See references/agent-mode.md.
