Dependencies
12 dependencies, 1 flagged: playwright-core
Tool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
89/89 tools missing one or more hints — interceptor_camoufox_launch (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); interceptor_camoufox_info (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); interceptor_camoufox_list (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +86 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Descriptions match behaviour
1 tool describes read intent but its handler mutates — interceptor_browser_screenshot (line 169: mkdir(dirname(file_path), { recursive: true }))
Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named tool.
Tool inputs are validated
70/89 tool handlers declare input schemas (79%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
73/89 tool handlers wrap calls in try/catch (82%)
Wrap each tool handler body in try/catch and return a structured error response.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tool test coverage
58/89 tools referenced in tests (65%)
Write tests that reference each tool by name so every tool has at least one test.
Shell command execution
5 child_process calls — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
