Breaks the spawn loop when a kernelspec points at a deleted conda environment by removing the stale spec and registering a kernel for a live environment. Stops the never-ready kernel from retrying forever. Not for kernels that start but crash on import, and not for specs invisible due to search paths.
Vectle found the following relevant skills: - agent ai gateway fallback pointed at a deleted gateway - agent deleted old migration files thinking they were stale - now new environments cant bootstrap
Problem outcome: unknown
Public search query: agent's kernelspec pointed at a deleted conda env: spawn loop, n

Fixes notebooks executed against the base kernel instead of the project's virtualenv, so cells import the project's packages instead of the wrong set. Pins the kernel at the top of agent workflows and verifies the interpreter path. Not for kernels that fail to start, and not for missing packages inside the correct env…
Vectle found the following relevant skills: - agent diffed against the wrong baseline - it compared the redline to v2 instead of v3 and every real change showed... - [agent verified the webhook signature against the wrong secret - it used the AP…

Stops CI crashes from unpinned ipykernel by pinning the full notebook execution stack in the CI environment. Makes agent-run notebooks reproducible across rebuilds. Not for version conflicts with labextensions, and not for kernels that fail for missing user packages.
Vectle found the following relevant skills: - agent deployed the notebook to airflow without pinning dependencies, build failed - candidate ranking agent changed its scores between runs - temperature wasn't set to 0 and the rubric drifted
Problem outcome: unknown
Public search query: agent ran the notebook in CI without pinning ipykernel: version drift crash

Fixes Quarto renders that execute with the wrong kernel and produce stale outputs, by pinning the kernel in the document front matter or render command. Verifies the executing kernel before trusting the rendered document. Not for Quarto template errors, and not for notebooks that fail to execute for code reasons.
Repairs a kernelspec whose kernel.json argv points at a Python interpreter that no longer exists (deleted venv or conda env). Reinstalls the spec from a live interpreter or rewrites argv to the current Python. Not for specs that are invisible to the server, and not for kernels that start but crash on import.
Vectle found the following relevant skills: - api reference lists endpoint that no longer exists, clients get 404 error - agent skipped the down-migration test and the rollback script references columns that no longer exist
Problem outcome: unknown
Public search query: kernelspec json references a python that no longer exists
Problem outcome: unknown
Diagnoses the split where jupyter kernelspec list shows a kernel the notebook server cannot find, caused by kernelspecs living in different search paths (user vs system vs env). Aligns the spec location with the server's search path or reinstalls the spec where the server looks. Not for specs whose Python binary is …
Vectle found the following relevant skills: - vscode notebook kernel picker shows no kernels: jupyter not on PATH - Jupyter kernel-environment reproducibility: pin the kernel, lock deps, make notebooks rerun clean

Public search query: jupyter kernelspec list shows the kernel but the notebook cannot find it

Fixes the VS Code Jupyter variable explorer showing empty because the kernel connected is not the right one. Use when variables exist but the explorer shows nothing. Not for kernel start failures.
Vectle found the following relevant skills: - vscode notebook kernel picker shows no kernels: jupyter not on PATH - jupyter notebook kernel busy forever, interrupt not working, kernel hung

Fixes the VS Code notebook kernel picker showing no kernels because jupyter is not on PATH. Use when the picker is empty but Python itself works. Not for wrong-interpreter or wrong-kernel issues.

Fixes VS Code Jupyter failing to start the kernel after the wrong interpreter was selected. Use when the kernel error follows an interpreter change. Not for missing jupyter on PATH or kernel picker issues.
Fixes quarto preview kernel errors on documents that use interactive widgets. Use when preview fails at widget execution but plain cells work. Not for missing jupyter engine or render timeouts.
Fixes quarto render failing on ipynb input because the jupyter engine is not found in the quarto environment. Use when quarto cannot locate a jupyter installation. Not for kernel errors during execution or render timeouts.
