From e62aa176529f519bcd1e4eba068e9643dd87639f Mon Sep 17 00:00:00 2001 From: zhaozian <1161954287@qq.com> Date: Fri, 18 Sep 2026 16:49:59 +0800 Subject: [PATCH 1/2] feat(browser): discover and drive nonstandard controls Whitelist-only snapshots missed div buttons, design-system date/select triggers, and overlay year/month cells; click() alone also failed to open mousedown/focus pickers. Add heuristics with depth, hidden forms, full pointer sequences, overlay leaves, selector/text addressing, and safer Enter. Harden review findings: keep full-document ids under region snapshots, require floating evidence for overlays, always mask CSS-hidden form values, surface invalid selectors as bad-args, and bound upload reads while accumulating short FileHandle.read returns until EOF. --- README.i18n.yaml | 4 +- README.md | 19 +- README.zh.md | 17 +- extensions/dsh-browser/manifest.firefox.json | 2 +- extensions/dsh-browser/manifest.json | 2 +- extensions/dsh-browser/package.json | 2 +- .../src/background/authorization.ts | 56 ++- .../dsh-browser/src/background/tools.ts | 12 +- extensions/dsh-browser/src/content/actions.ts | 471 ++++++++++++++++-- extensions/dsh-browser/src/content/extract.ts | 468 ++++++++++++++++- extensions/dsh-browser/src/content/index.ts | 2 +- extensions/dsh-browser/src/content/privacy.ts | 6 + .../dsh-browser/src/content/snapshot.ts | 217 ++++++-- .../tests/actions-addressing.spec.ts | 177 +++++++ .../dsh-browser/tests/actions-delta.spec.ts | 2 +- .../tests/actions-pointer-click.spec.ts | 101 ++++ .../tests/actions-security.spec.ts | 2 +- .../dsh-browser/tests/actions-settle.spec.ts | 8 +- .../tests/actions-type-rich-text.spec.ts | 2 +- .../dsh-browser/tests/authorization.spec.ts | 18 + extensions/dsh-browser/tests/extract.spec.ts | 158 +++++- .../tests/fixtures/nonstandard-controls.html | 146 ++++++ .../dsh-browser/tests/overlay-cells.spec.ts | 132 +++++ extensions/dsh-browser/tests/privacy.spec.ts | 2 +- extensions/dsh-browser/tests/setup.ts | 8 + .../tests/snapshot-dialog-priority.spec.ts | 2 +- extensions/dsh-browser/tests/snapshot.spec.ts | 64 ++- packages/browser/bridge-browser/package.json | 2 +- packages/browser/bridge-browser/src/tools.ts | 247 ++++++++- .../bridge-browser/tests/tools.spec.ts | 132 ++++- 30 files changed, 2339 insertions(+), 142 deletions(-) create mode 100644 extensions/dsh-browser/tests/actions-addressing.spec.ts create mode 100644 extensions/dsh-browser/tests/actions-pointer-click.spec.ts create mode 100644 extensions/dsh-browser/tests/fixtures/nonstandard-controls.html create mode 100644 extensions/dsh-browser/tests/overlay-cells.spec.ts diff --git a/README.i18n.yaml b/README.i18n.yaml index d17f0a8e4..b8f10b626 100644 --- a/README.i18n.yaml +++ b/README.i18n.yaml @@ -1,5 +1,5 @@ # Bilingual consistency record for the repository README files. # README.md is the default English page; README.zh.md is its Chinese counterpart. # Values are git blob hashes from the last confirmed-consistent review. -README.md: 84ed56450ad1753959304392f90f8a8fccd582d2 -README.zh.md: e3bed42749b6e7dfd60a06fc423926fa381cadea +README.md: c93ff03a45106e3eacd26ff9f2f37f848ce83607 +README.zh.md: a4566ac140b718edd9f0ca79306d3b29bb2f5362 diff --git a/README.md b/README.md index 84ed56450..fa53c90ff 100644 --- a/README.md +++ b/README.md @@ -49,10 +49,12 @@ The paired Playwright / extension duration ratio was **1.24** (95% CI **1.16–1 | Capability | Tool | Notes | |---|---|---| -| Read page | `browser_snapshot` | Structured text snapshot: title, URL, main text, numbered controls, and masked form fields; `delta: true` returns only changes | -| Click element | `browser_click` | Click links, buttons, checkboxes, and other controls by inventory number | -| Fill forms | `browser_type` | React/Vue-compatible input; `replace` clears the field first | -| Press keys | `browser_press` | Keyboard events such as Enter, Tab, Escape, and arrow keys | +| Read page | `browser_snapshot` | Structured text snapshot: title, URL, main text, numbered controls (including heuristic clickables), and masked form fields; `region` scopes text **and** inventory; `delta: true` returns only changes | +| Click element | `browser_click` | Click by snapshot index, CSS selector, or visible text (exactly one).
