* feat(browser): store full snapshots on truncation; make eval denylist opt-in Two harness fixes motivated by BU_Bench results where fixed-verb + lossy observation cost Hermes heavily vs code-driven browser agents: 1. Snapshot truncation no longer loses content. When a snapshot exceeds the 8000-char threshold, the complete accessibility tree is saved to cache/web (same truncate-and-store pattern as web_extract) and the truncated view / LLM summary includes the file path plus a ready-made read_file call. Element refs beyond the cut are recoverable without re-snapshotting. Stored copies are force-redacted and capped at 2MB; content-hash filenames dedupe repeated snapshots of the same page. 2. The browser_console(expression=...) sensitive-primitive denylist is now opt-in via browser.restrict_evaluate (default false). The names-based denylist blocked legitimate DOM extraction — any selector or expression containing 'fetch', 'cookie', 'input', etc. — which crippled the agent's only programmatic page-inspection path. The SSRF/private-URL egress guards in _browser_eval are independent of this policy and remain always-on. browser.allow_unsafe_evaluate keeps its meaning (bypass the denylist) for configs that already set it. * test: update None-guard test for stored-snapshot pointer in _extract_relevant_content test_normal_content_returned pinned the exact return value; the summary now carries a pointer to the stored full snapshot. Assert the summary passes through and the pointer is present instead. * feat(browser): align snapshot threshold with web_extract's 15k char budget SNAPSHOT_SUMMARIZE_THRESHOLD 8000 -> 15000, matching web_tools.DEFAULT_EXTRACT_CHAR_LIMIT so the snapshot and web_extract truncate-and-store paths give the model the same per-page budget. _truncate_snapshot's default max_chars now follows the constant. Invariant test added; docs (en+zh) and CLI tip updated. |
