At a glance

Fast headless browser for QA testing and site dogfooding. An agent skill from mr-daedalium/ostack-saas.

  • Works in 11 steps: Verify a page loads correctly → Test a user flow → Verify an action worked → …
  • You need to test a feature
  • SKILL.md covers Preamble (run first), AskUserQuestion Format, Conviction and Completeness —… and Repo Ownership Mode — See…, plus 9 more sections
  • Runs TypeScript, Shell and JavaScript scripts from its folder; calls git, codex and curl; reaches bun.sh

What it does

Browse is an agent skill from mr-daedalium/ostack-saas. Fast headless browser for QA testing and site dogfooding. Navigate any URL, interact with elements, verify page state, diff before/after actions, take annotated screenshots, check responsive layouts, test forms and uploads, handle dialogs, and assert element states. ~100ms per command. Use when you need to test a feature, verify a deployment, dogfood a user flow, or file a bug with evidence. Use when asked to "open in browser", "test the site", "take a screenshot", or "dogfood this".

Its SKILL.md is about 5.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 53 other files, including scripts (for example `scripts/build-node-server.sh`, `src/browser-manager.ts` and `src/buffers.ts`).

It sits in Productivity & Automation, covering UX design, Responsive design and QA and bug reports. The repository describes itself as: ostack — AI-powered engineering team for Claude Code. Fork of gstack by Garry Tan. The licence is MIT.

When your agent uses it

  • You need to test a feature
  • Verify a deployment
  • Dogfood a user flow
  • File a bug with evidence

Example prompts

  • “open in browser”
  • “test the site”
  • “take a screenshot”
  • “/browse”

Requirements

  • Node.js
  • A Bash shell
  • Pre-approved tools (allowed-tools): Bash, Read, AskUserQuestion

Workflow steps

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

  1. Verify a page loads correctly
  2. Test a user flow
  3. Verify an action worked
  4. Visual evidence for bug reports
  5. Find all clickable elements (including non-ARIA)
  6. Assert element states
  7. Test responsive layouts
  8. Test file uploads
  9. Test dialogs
  10. Compare environments
  11. Show screenshots to the user

What it can do on your machine

Read from SKILL.md and the folder at commit a67256d. 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:

    • Bash
    • Read
    • AskUserQuestion

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (TypeScript, Shell and JavaScript, from the files we listed), which the agent can run.

    Shell commands in SKILL.md call:

    • git
    • codex
    • curl
    • bash

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

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • bun.sh

    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

Browse loads about 5.3k tokens when it runs. Until then it costs about 124 tokens; SKILL.md has 2,102 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~124
When it runs · the whole SKILL.md, loaded when a task matches
~5.3k

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.

  • NotePipes a well-known installer script into a shellSKILL.md:232
    3. If `bun` is not installed: `curl -fsSL https://bun.sh/install | bash`
  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    allowed-tools: Bash, Read, AskUserQuestion

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); the scripts in this folder are not scanned.

Preamble (run first)

bash
_UPD=$(~/.claude/skills/ostack/bin/ostack-update-check 2>/dev/null || .claude/skills/ostack/bin/ostack-update-check 2>/dev/null || true)
[ -n "$_UPD" ] && echo "$_UPD" || true
mkdir -p ~/.ostack/sessions
touch ~/.ostack/sessions/"$PPID"
_SESSIONS=$(find ~/.ostack/sessions -mmin -120 -type f 2>/dev/null | wc -l | tr -d ' ')
find ~/.ostack/sessions -mmin +120 -type f -delete 2>/dev/null || true
_CONTRIB=$(~/.claude/skills/ostack/bin/ostack-config get ostack_contributor 2>/dev/null || true)
_PROACTIVE=$(~/.claude/skills/ostack/bin/ostack-config get proactive 2>/dev/null || echo "true")
_BRANCH=$(git branch --show-current 2>/dev/null || echo "unknown")
echo "BRANCH: $_BRANCH"
echo "PROACTIVE: $_PROACTIVE"
source <(~/.claude/skills/ostack/bin/ostack-repo-mode 2>/dev/null) || true
REPO_MODE=${REPO_MODE:-unknown}
echo "REPO_MODE: $REPO_MODE"

If PROACTIVE is "false", do not proactively suggest ostack skills — only invoke them when the user explicitly asks. The user opted out of proactive suggestions.

If output shows UPGRADE_AVAILABLE <old> <new>: read ~/.claude/skills/ostack/ostack-upgrade/SKILL.md and follow the "Inline upgrade flow" (auto-upgrade if configured, otherwise AskUserQuestion with 4 options, write snooze state if declined). If JUST_UPGRADED <from> <to>: tell user "Running ostack v{to} (just updated!)" and continue.

AskUserQuestion Format

ALWAYS follow this structure:

  1. Recommendation: "Do X because Y." One sentence. Position first.
  2. Options: A) ... B) ... — two options, three max if genuinely needed. When an option involves effort, show both scales: (human: ~X / CC: ~Y)

Skip AskUserQuestion entirely if there's a clear right answer — just do it and report.

Never hedge. Never pad with "great question." Never restate context the user already has. Compress ruthlessly. Trust the user to keep up.

Conviction and Completeness — Often Wrong, Never in Doubt

AI makes the marginal cost of completeness near-zero. Do the complete thing. But the deeper question is whether you're completing the right thing.

Say No to 1000 Things

Completeness without focus is waste. Before going deep, ask: is this the highest-leverage thing to build right now? If not, stop. The power of AI-assisted development is not doing everything — it's doing the right thing completely and fast. Say no to everything else.

Iteration as Truth

Rapid collision with reality beats analysis. Ship the smallest thing that tests the riskiest assumption. Wrong fast is better than right slow. Conviction means committing to a direction, shipping it, and course-correcting from real signal — not hedging with half-implementations.

Power Law

Concentrate effort, don't diversify. One complete feature beats three half-finished ones. One well-tested path beats broad shallow coverage. Find the 20% of work that drives 80% of value and do that completely.

When to be complete

Once you've decided something is worth doing:

  • Always recommend the complete implementation over shortcuts. The delta between 80 lines and 150 lines is meaningless with CC+ostack.
  • Effort estimation — always show both scales:
Task typeHuman teamCC+ostackCompression
Boilerplate / scaffolding2 days15 min~100x
Test writing1 day15 min~50x
Feature implementation1 week30 min~30x
Bug fix + regression test4 hours15 min~20x
Architecture / design2 days4 hours~5x
Research / exploration1 day3 hours~3x
  • This applies to test coverage, error handling, edge cases, and feature completeness. Don't skip the last 10% to "save time" — with AI, that 10% costs seconds.
  • Scope guard: A boilable lake = full test coverage for a module, complete feature implementation, all edge cases. An ocean = rewriting systems from scratch, multi-quarter migrations. Do lakes. Flag oceans.

Repo Ownership Mode — See Something, Say Something

REPO_MODE from the preamble tells you who owns issues in this repo:

  • solo — One person does 80%+ of the work. They own everything. When you notice issues outside the current branch's changes (test failures, deprecation warnings, security advisories, linting errors, dead code, env problems), investigate and offer to fix proactively. The solo dev is the only person who will fix it. Default to action.
  • collaborative — Multiple active contributors. When you notice issues outside the branch's changes, flag them via AskUserQuestion — it may be someone else's responsibility. Default to asking, not fixing.
  • unknown — Treat as collaborative (safer default — ask before fixing).

See Something, Say Something: Whenever you notice something that looks wrong during ANY workflow step — not just test failures — flag it briefly. One sentence: what you noticed and its impact. In solo mode, follow up with "Want me to fix it?" In collaborative mode, just flag it and move on.

Never let a noticed issue silently pass. The whole point is proactive communication.

Search Before Building

Before building infrastructure, unfamiliar patterns, or anything the runtime might have a built-in — search first. Read ~/.claude/skills/ostack/ETHOS.md for the full philosophy.

Three layers of knowledge:

  • Layer 1 (tried and true — in distribution). Don't reinvent the wheel. But the cost of checking is near-zero, and once in a while, questioning the tried-and-true is where brilliance occurs.
  • Layer 2 (new and popular — search for these). But scrutinize: humans are subject to mania. Search results are inputs to your thinking, not answers.
  • Layer 3 (first principles — prize these above all). Original observations derived from reasoning about the specific problem. The most valuable of all.

Eureka moment: When first-principles reasoning reveals conventional wisdom is wrong, name it clearly: "EUREKA: Everyone does X because [assumption]. But [evidence] shows this is wrong. Y is better because [reasoning]."

Carry that insight into the rest of the skill instead of treating it like a side note.

WebSearch fallback: If WebSearch is unavailable, skip the search step and note: "Search unavailable — proceeding with in-distribution knowledge only."

Contributor Mode

If _CONTRIB is true: you are in contributor mode. You're a ostack user who also helps make it better.

At the end of each major workflow step (not after every single command), reflect on the ostack tooling you used. Rate your experience 0 to 10. If it wasn't a 10, think about why. If there is an obvious, actionable bug OR an insightful, interesting thing that could have been done better by ostack code or skill markdown — file a field report. Maybe our contributor will help make us better!

Calibration — this is the bar: For example, $B js "await fetch(...)" used to fail with SyntaxError: await is only valid in async functions because ostack didn't wrap expressions in async context. Small, but the input was reasonable and ostack should have handled it — that's the kind of thing worth filing. Things less consequential than this, ignore.

NOT worth filing: user's app bugs, network errors to user's URL, auth failures on user's site, user's own JS logic bugs.

To file: write ~/.ostack/contributor-logs/{slug}.md with all sections below (do not truncate — include every section through the Date/Version footer):

# {Title}

Hey ostack team — ran into this while using /{skill-name}:

**What I was trying to do:** {what the user/agent was attempting}
**What happened instead:** {what actually happened}
**My rating:** {0-10} — {one sentence on why it wasn't a 10}

## Steps to reproduce
1. {step}

## Raw output

{paste the actual error or unexpected output here}


## What would make this a 10
{one sentence: what ostack should have done differently}

**Date:** {YYYY-MM-DD} | **Version:** {ostack version} | **Skill:** /{skill}

Slug: lowercase, hyphens, max 60 chars (e.g. browse-js-no-await). Skip if file already exists. Max 3 reports per session. File inline and continue — don't stop the workflow. Tell user: "Filed ostack field report: {title}"

Completion Status Protocol

When completing a skill workflow, report status using one of:

  • DONE — All steps completed successfully. Evidence provided for each claim.
  • DONE_WITH_CONCERNS — Completed, but with issues the user should know about. List each concern.
  • BLOCKED — Cannot proceed. State what is blocking and what was tried.
  • NEEDS_CONTEXT — Missing information required to continue. State exactly what you need.
Escalation

It is always OK to stop and say "this is too hard for me" or "I'm not confident in this result."

Bad work is worse than no work. You will not be penalized for escalating.

  • If you have attempted a task 3 times without success, STOP and escalate.
  • If you are uncertain about a security-sensitive change, STOP and escalate.
  • If the scope of work exceeds what you can verify, STOP and escalate.

Escalation format:

STATUS: BLOCKED | NEEDS_CONTEXT
REASON: [1-2 sentences]
ATTEMPTED: [what you tried]
RECOMMENDATION: [what the user should do next]

When you are in plan mode and about to call ExitPlanMode:

  1. Check if the plan file already has a ## OSTACK REVIEW REPORT section.
  2. If it DOES — skip (a review skill already wrote a richer report).
  3. If it does NOT — run this command:

```bash ~/.claude/skills/ostack/bin/ostack-review-read ```

Then write a ## OSTACK REVIEW REPORT section to the end of the plan file:

  • If the output contains review entries (JSONL lines before ---CONFIG---): format the standard report table with runs/status/findings per skill, same format as the review skills use.
  • If the output is NO_REVIEWS or empty: write this placeholder table:

browse: QA Testing & Dogfooding

Persistent headless Chromium. First call auto-starts (~3s), then ~100ms per command. State persists between calls (cookies, tabs, login sessions).

SETUP (run this check BEFORE any browse command)

bash
_ROOT=$(git rev-parse --show-toplevel 2>/dev/null)
B=""
[ -n "$_ROOT" ] && [ -x "$_ROOT/.claude/skills/ostack/browse/dist/browse" ] && B="$_ROOT/.claude/skills/ostack/browse/dist/browse"
[ -z "$B" ] && B=~/.claude/skills/ostack/browse/dist/browse
if [ -x "$B" ]; then
  echo "READY: $B"
else
  echo "NEEDS_SETUP"
fi

If NEEDS_SETUP:

  1. Tell the user: "ostack browse needs a one-time build (~10 seconds). OK to proceed?" Then STOP and wait.
  2. Run: cd <SKILL_DIR> && ./setup
  3. If bun is not installed: curl -fsSL https://bun.sh/install | bash

Core QA Patterns

1. Verify a page loads correctly
bash
$B goto https://yourapp.com
$B text                          # content loads?
$B console                       # JS errors?
$B network                       # failed requests?
$B is visible ".main-content"    # key elements present?
2. Test a user flow
bash
$B goto https://app.com/login
$B snapshot -i                   # see all interactive elements
$B fill @e3 "user@test.com"
$B fill @e4 "password"
$B click @e5                     # submit
$B snapshot -D                   # diff: what changed after submit?
$B is visible ".dashboard"       # success state present?
3. Verify an action worked
bash
$B snapshot                      # baseline
$B click @e3                     # do something
$B snapshot -D                   # unified diff shows exactly what changed
4. Visual evidence for bug reports
bash
$B snapshot -i -a -o /tmp/annotated.png   # labeled screenshot
$B screenshot /tmp/bug.png                # plain screenshot
$B console                                # error log
5. Find all clickable elements (including non-ARIA)
bash
$B snapshot -C                   # finds divs with cursor:pointer, onclick, tabindex
$B click @c1                     # interact with them
6. Assert element states
bash
$B is visible ".modal"
$B is enabled "#submit-btn"
$B is disabled "#submit-btn"
$B is checked "#agree-checkbox"
$B is editable "#name-field"
$B is focused "#search-input"
$B js "document.body.textContent.includes('Success')"
7. Test responsive layouts
bash
$B responsive /tmp/layout        # mobile + tablet + desktop screenshots
$B viewport 375x812              # or set specific viewport
$B screenshot /tmp/mobile.png
8. Test file uploads
bash
$B upload "#file-input" /path/to/file.pdf
$B is visible ".upload-success"
9. Test dialogs
bash
$B dialog-accept "yes"           # set up handler
$B click "#delete-button"        # trigger dialog
$B dialog                        # see what appeared
$B snapshot -D                   # verify deletion happened
10. Compare environments
bash
$B diff https://staging.app.com https://prod.app.com
11. Show screenshots to the user

After $B screenshot, $B snapshot -a -o, or $B responsive, always use the Read tool on the output PNG(s) so the user can see them. Without this, screenshots are invisible.

User Handoff

When you hit something you can't handle in headless mode (CAPTCHA, complex auth, multi-factor login), hand off to the user:

bash
# 1. Open a visible Chrome at the current page
$B handoff "Stuck on CAPTCHA at login page"

# 2. Tell the user what happened (via AskUserQuestion)
#    "I've opened Chrome at the login page. Please solve the CAPTCHA
#     and let me know when you're done."

# 3. When user says "done", re-snapshot and continue
$B resume

When to use handoff:

  • CAPTCHAs or bot detection
  • Multi-factor authentication (SMS, authenticator app)
  • OAuth flows that require user interaction
  • Complex interactions the AI can't handle after 3 attempts

The browser preserves all state (cookies, localStorage, tabs) across the handoff. After resume, you get a fresh snapshot of wherever the user left off.

Snapshot Flags

The snapshot is your primary tool for understanding and interacting with pages.

-i        --interactive           Interactive elements only (buttons, links, inputs) with @e refs
-c        --compact               Compact (no empty structural nodes)
-d <N>    --depth                 Limit tree depth (0 = root only, default: unlimited)
-s <sel>  --selector              Scope to CSS selector
-D        --diff                  Unified diff against previous snapshot (first call stores baseline)
-a        --annotate              Annotated screenshot with red overlay boxes and ref labels
-o <path> --output                Output path for annotated screenshot (default: <temp>/browse-annotated.png)
-C        --cursor-interactive    Cursor-interactive elements (@c refs — divs with pointer, onclick)

All flags can be combined freely. -o only applies when -a is also used. Example: $B snapshot -i -a -C -o /tmp/annotated.png

Ref numbering: @e refs are assigned sequentially (@e1, @e2, ...) in tree order. @c refs from -C are numbered separately (@c1, @c2, ...).

After snapshot, use @refs as selectors in any command:

bash
$B click @e3       $B fill @e4 "value"     $B hover @e1
$B html @e2        $B css @e5 "color"      $B attrs @e6
$B click @c1       # cursor-interactive ref (from -C)

Output format: indented accessibility tree with @ref IDs, one element per line.

  @e1 [heading] "Welcome" [level=1]
  @e2 [textbox] "Email"
  @e3 [button] "Submit"

Refs are invalidated on navigation — run snapshot again after goto.
