version: "1.0.0" name: working-with-bash-and-pyodide description: Use when running Bash commands, processing data with Python, performing symbolic calculations, fetching video transcripts, or interacting with Logseq through logseq_lib. disable-model-invocation: false built-in-skill: true built-in-skill-user-controllable: false

Working with Bash

The Bash tool runs in a virtual read-only filesystem.

Reading a file in the skill store

<% #includeFile %>internal/READ_SKILL_FILE.sh<% /includeFile %>

Working with Pyodide

Pyodide is available in the Bash environment with the same read-only virtual filesystem. Use python, python3, or py to run Python 3.14. Skills and command files can be modified through logseq_lib, which also provides programmatic access to Logseq pages and blocks.

Pyodide supports external Pyodide-compatible packages through micropip. Always pin exact versions, and install and use packages in the same command. Packages are not preserved between Bash tool invocations, and there is no pip wheel cache.

Basic Usage Examples

Symbolic integration

Use SymPy to integrate x**2 and print the result as LaTeX:

python - <<'PY'
<% #includeFile %>internal/SYMPY_INTEGRATION.py<% /includeFile %>
PY

YouTube transcript

Fetch a public English transcript with youtube-transcript-api:

python - <<'PY'
<% #includeFile %>internal/YOUTUBE_TRANSCRIPT.py<% /includeFile %>
PY

For Bilibili, check <% &virEnvUserPath %>/skills/working-with-bash-and-pyodide/examples/BILIBILI_TRANSCRIPT.py.

Convert an existing PNG asset to grayscale

python - <<'PY'
<% #includeFile %>internal/GRAYSCALE_ASSET.py<% /includeFile %>
PY

Using Logseq Lib

Import logseq_lib and await its methods with a single argument dictionary. Similar to your tools, you need to run the commit tool to persist changes.

Listing available Logseq methods

python - <<'PY'
<% #includeFile %>internal/LIST_LOGSEQ_METHODS.py<% /includeFile %>
PY

Creating a page and a child block

python - <<'PY'
<% #includeFile %>internal/CREATE_PAGE.py<% /includeFile %>
PY

Creating a skill

python - <<'PY'
<% #includeFile %>internal/CREATE_SKILL.py<% /includeFile %>
PY

You can pair the above command with read_raw_skill to modify existing skills.
