Summary

  • type command: No longer echoes typed text; reports character count instead (Typed 12 characters)
  • cookie command: Redacts cookie value in output (Cookie set: name=****)
  • header command: Redacts values for sensitive headers (Authorization, Cookie, Set-Cookie, X-API-Key, X-Auth-Token); non-sensitive headers remain visible
  • forms command: Replaces password field values with [redacted] instead of dumping actual values
  • storage set command: Drops the value from the confirmation message

Why

In an LLM-agent context, command output is fed back into model context and persisted in logs/transcripts. Commands like type, cookie, and header were reflecting secrets (passwords, auth tokens, API keys) directly into stdout, creating a security risk.

Fixes #18

Test plan

  • Run browse type <password> and verify output says Typed N characters without echoing the text
  • Run browse cookie session=secret123 and verify output shows Cookie set: session=****
  • Run browse header Authorization:Bearer token123 and verify output shows Header set: Authorization: ****
  • Run browse header Content-Type:application/json and verify non-sensitive header value is still shown
  • Load a page with a password form field via browse forms and verify password values show [redacted]
  • Run browse storage set key value and verify output shows Set localStorage["key"] without the value

🤖 Generated with Claude Code

Prevent secrets and sensitive data from leaking into stdout and model
transcripts by redacting output from type, cookie, header, forms, and
storage commands.

Fixes garrytan#18

* Phase 2: Enhanced browser — dialog handling, upload, state checks, snapshots

- CircularBuffer O(1) ring buffer for console/network/dialog (was O(n) array+shift)
- Async buffer flush with Bun.write() (was appendFileSync)
- Dialog auto-accept/dismiss with buffer + prompt text support
- File upload command (upload <sel> <file...>)
- Element state checks (is visible/hidden/enabled/disabled/checked/editable/focused)
- Annotated screenshots with ref labels overlaid (-a flag)
- Snapshot diffing against previous snapshot (-D flag)
- Cursor-interactive element scan for non-ARIA clickables (-C flag)
- Snapshot scoping depth limit (-d N flag)
- Health check with page.evaluate + 2s timeout
- Playwright error wrapping — actionable messages for AI agents
- Fix useragent — context recreation preserves cookies/storage/URLs
- wait --networkidle / --load / --domcontentloaded flags
- console --errors filter (error + warning only)
- cookie-import <json-file> with auto-fill domain from page URL
- 166 integration tests (was ~63)

* Phase 2: Rewrite SKILL.md as QA playbook + command reference

Reorient SKILL.md files from raw command reference to QA-first playbook
with 10 workflow patterns (test user flows, verify deployments, dogfood
features, responsive layouts, file upload, forms, dialogs, compare pages).
Compact command reference tables at the bottom.

* Phase 3: /qa skill — systematic QA testing with health scores

New /qa skill for systematic web app QA testing. Three modes:
- full: 5-10 documented issues with screenshots and repro steps
- quick: 30-second smoke test with health score
- regression: compare against saved baseline

Includes issue taxonomy (7 categories, 4 severity levels), structured
report template, health score rubric (weighted across 7 categories),
framework detection guidance (Next.js, Rails, WordPress, SPA).

Also adds browse/bin/find-browse (DRY binary discovery using git
rev-parse), .gstack/ to .gitignore, and updated TODO roadmap.

* Bump to v0.3.0 — Phase 2 + Phase 3 changelog

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* feat: cookie-import-browser — Chromium cookie decryption module + tests

Pure logic module for reading and decrypting cookies from macOS Chromium
browsers (Comet, Chrome, Arc, Brave, Edge). Supports v10 AES-128-CBC
encryption with macOS Keychain access, PBKDF2 key derivation, and
per-browser key caching. 18 unit tests with encrypted cookie fixtures.

* feat: cookie picker web UI + route handler

Two-panel dark-theme picker served from the browse server. Left panel
shows source browser domains with search and import buttons. Right panel
shows imported domains with trash buttons. No cookie values exposed.
6 API endpoints, importedDomains Set tracking, inline clearCookies.

* feat: wire cookie-import-browser into browse server

Add cookie-picker route dispatch (no auth, localhost-only), add
cookie-import-browser to WRITE_COMMANDS and CHAIN_WRITE, add serverPort
property to BrowserManager, add write command with two modes (picker UI
vs --domain direct import), update CLI help text.

* chore: /setup-browser-cookies skill + docs (Phase 3.5)

* security: redact sensitive values from command output (PR #21)

type no longer echoes text (reports character count), cookie redacts
value with ****, header redacts Authorization/Cookie/X-API-Key/X-Auth-Token,
storage set drops value, forms redacts password fields. Prevents secrets
from persisting in LLM transcripts. 7 new tests.

* security: path traversal prevention for screenshot/pdf/eval (PR #26)

Add validateOutputPath() for screenshot/pdf/responsive (restricts to
/tmp and cwd) and validateReadPath() for eval (blocks .. sequences and
absolute paths outside safe dirs). 7 new tests.

* fix: auto-install Playwright Chromium in setup (PR #22)

Setup now verifies Playwright can launch Chromium, and auto-installs
it via `bunx playwright install chromium` if missing. Exits non-zero
if build or Chromium launch fails.

* security: fix path validation bypass, CORS restriction, cookie-import path check

- startsWith('/tmp') matched '/tmpevil' — now requires trailing slash
- CORS Access-Control-Allow-Origin changed from * to http://127.0.0.1:<port>
- cookie-import now validates file paths (was missing validateReadPath)
- 3 new tests for prefix collision and cookie-import path traversal

* fix: address review informational issues + add regression tests

- Add cookie-import to CHAIN_WRITE set for chain command routing
- Add path validation to snapshot -a -o output path
- Fix package.json version to match 0.3.1
- Use crypto.randomUUID() for temp DB paths (unpredictable filenames)
- Add regression tests for chain cookie-import and snapshot path validation

- Add dedicated README sections for both new skills with usage examples
- Update demo workflow to show cookie import → QA → browse flow
- Update BROWSER.md: cookie import commands, new source files, test count (203)
- Update skill count from 6 to 8
