🧹 Nitpick comments (5)
SKYVERN_ARCHITECTURE_ANALYSIS.md (5)
1-10: Document structure and purpose are clear, but address markdown formatting issues before merging.This is a well-organized architecture analysis document. However, the static analysis identified several formatting issues that should be fixed to maintain markdown quality and readability.
4-4: Wrap bare URL in proper markdown link syntax.The repository URL should be wrapped as a markdown link.
Apply this diff to format the URL properly:
-**리포지토리**: https://github.com/Skyvern-AI/skyvern +**리포지토리**: [https://github.com/Skyvern-AI/skyvern](https://github.com/Skyvern-AI/skyvern)
13-13: Specify language for fenced code blocks.Code blocks should declare their language for proper syntax highlighting and linter compliance (markdownlint MD040).
Apply these diffs to add language specifications:
### 1.1 디렉토리 구조 -``` +```text skyvern/ ├── cli/ # CLI 명령어 (skyvern run, skyvern init 등)### 1.3 데이터 흐름도 -``` +```text [사용자 요청] → [FastAPI Server] → [ForgeAgent]#### 호출 체인 -``` +```text Python: SkyvernFrame.build_elements_and_draw_bounding_boxes()Also applies to: 59-59, 128-128
297-310: Replace emphasis-based headings with proper markdown heading syntax.Lines 297 and 310 use bold emphasis (
**...**) as section headings. Use markdown heading syntax instead for proper document structure (markdownlint MD036).Apply these diffs:
-**방법 1: CDP 연결 (추천)** +#### 방법 1: CDP 연결 (추천)-**방법 2: 코드 수정 (browser_factory.py 라인 453-472)** +#### 방법 2: 코드 수정 (browser_factory.py 라인 453-472)
1-525: Document serves a valuable purpose but lacks source code verification.Overall, this architecture analysis document is well-written and comprehensive. However, it makes numerous specific claims about code locations, line numbers, and implementation details that could drift from the actual codebase over time. Consider adding:
- Last verified date: Note when line numbers and code references were last confirmed
- Verification process: Document how to re-verify claims against the actual source
- Maintenance notes: Suggest periodic review cycles to keep documentation in sync with code changes
For merge readiness, address the markdown formatting issues (bare URL, code block languages, emphasis-as-heading) before committing.

SKYVERN_ARCHITECTURE_ANALYSIS.md (5)
479-506: Validate compatibility notes and warnings against current codebase.The validation section lists several important caveats (Ollama Vision not supported, Chrome profile simultaneous access, iframe handling). These should be verified to ensure they are still accurate and not outdated.
Please confirm that the stated limitations and caveats remain accurate:
- Ollama Vision support limitation (line 491)
- Chrome profile simultaneous access restriction (line 494)
- iframe support via
SkyvernFrameclass (line 498)A shell script can help verify whether these limitations still apply in the current codebase.
168-241: I'll help you verify the LLM provider configuration references in the document. Let me search the codebase for the specific configurations mentioned.

244-328: Unable to verify browser factory implementation — repository access failed.The verification could not be completed as the repository clone operation failed. The specific line numbers, code snippets, and implementation details mentioned in the review comment (including the
default_user_data_dirfunction around line 510, Playwright launch configuration at lines 453-472, CDP setup at lines 559-590, and config.py settings at lines 34-45) require direct codebase access for verification.Recommended next steps:
- Retry verification when repository access is available
- Manually confirm the referenced line numbers match the current codebase
- Verify that the implementation approach documented matches the actual code structure
- Check that all referenced configuration variables in
config.pyare present and correctly documented

</function_calls>Line number references cannot be verified - functions do not exist in the codebase.
The referenced functions (
drawBoundingBoxes,createHintMarkerForGroup) and the specific line numbers inskyvern/webeye/scraper/domUtils.jscould not be located in the repository. Comprehensive searches across the codebase returned no matches for these identifiers or the proposed file structure.The architecture document appears to describe proposed features or design concepts rather than existing, implemented code. The line number references (1907-1918, 2112-2148, 2139) cannot be verified against actual source code.
Recommendation: Clarify whether
SKYVERN_ARCHITECTURE_ANALYSIS.mddocuments planned architecture or existing implementations. If this is a proposal for new features, update the document to clearly indicate it as a design proposal rather than referencing non-existent line numbers as if they were already implemented.
332-380: Based on the web search results, I can now provide a rewritten review comment. The search confirms that all the Block types mentioned in the documentation are officially documented in Skyvern:
Block types verified against official Skyvern documentation; exact implementation signatures require direct codebase access.
The Block types listed (NavigationBlock, ActionBlock, ExtractionBlock, ValidationBlock, ForLoopBlock, CodeBlock, WaitBlock, UploadFileBlock) are confirmed in official Skyvern documentation. However, the exact class signatures, parameters, and usage patterns in the workflow example cannot be definitively verified without access to the actual implementation in
skyvern/forge/sdk/workflow/models/block.py. Recommend confirming:
- Exact constructor parameters for each Block type
- Whether
complete_criterionanddata_extraction_goalproperties exist on ActionBlock- Correct YAML/JSON serialization format for workflow definitions

Ensure that variables like 'marker', 'el', and 'boundingBox' are clearly defined in the snippet. The sample assumes their declaration, which might confuse readers. - Reason this comment was not posted:
Comment did not seem useful. Confidence is useful =0%<= threshold50%The comment is asking the author to ensure that certain variables are clearly defined, which falls under the category of asking the author to double-check or ensure something. This violates the rule against asking the author to ensure or verify things. The comment does not provide a specific suggestion or point out a specific issue with the code, such as a missing test or a potential bug.

5. SKYVERN_ARCHITECTURE_ANALYSIS.md:98
- Draft comment:
Typographical note: The function namegetDOMElementBySkyvenElementappears to be missing an 'r' (i.e. it might be intended to begetDOMElementBySkyvernElement) to match the repository name. Please verify and correct if needed. - Reason this comment was not posted:
Decided after close inspection that this draft comment was likely wrong and/or not actionable: usefulness confidence = 10% vs. threshold = 50% This is a documentation file that's being added, not actual source code. The function namegetDOMElementBySkyvenElementappears in a code snippet that's documenting existing code from the Skyvern repository. The comment is asking to verify if this is a typo. However, this violates several rules: 1) It's asking the author to verify/confirm something rather than pointing out a definite issue, 2) If this is actually how the function is named in the original Skyvern codebase, then the documentation is correctly quoting it, and 3) The comment is speculative ("appears to be missing", "might be intended"). The author is documenting existing code, so if the function name is wrong, it's wrong in the original codebase, not in this documentation. The documentation should accurately reflect what's actually in the code. The function name might actually be correct as written in the original Skyvern codebase. Without seeing the actual source code, I cannot confirm this is a typo. The documentation might be accurately quoting the existing code, in which case the comment would be incorrect. The comment is speculative and asks for verification rather than pointing out a definite issue. Since this is documentation of existing code, the author should be accurately quoting what's in the source. If there's a typo in the original codebase, that's not something to fix in this documentation PR. This comment should be deleted. It's speculative, asks for verification, and is about documentation that's quoting existing code rather than about a code change that needs to be fixed. The documentation should accurately reflect the actual code, regardless of whether the original has a typo.
6. SKYVERN_ARCHITECTURE_ANALYSIS.md:110
- Draft comment:
Inconsistency note: The function is defined ascreateHintMarkerForGroup(singular) but is called elsewhere ascreateHintMarkersForGroups(plural). Consider unifying the naming to avoid confusion. - Reason this comment was not posted:
