One of 13 test cases the skill fixed. Same model, same prompt, with and without the skill.
I want to inspect the contents of a design asset file `brand_theme.json` located inside my presentation project file workspace. Which tool reads files from the project workspace?

The instructions your model reads when the skill loads.
The canonical codex-slides sibling skill owns the complete workflow. Use the
codex_slides MCP tools when available; otherwise run its self-contained CLI
at ../codex-slides/scripts/codex-slides.mjs. Keep the live workspace available
in the in-editor Browser whenever visual review helps.
Default to the live Browser workflow: open the Codex Slides home screen, submit the request there, then operate the created project through clarify, outline confirmation, style selection, rendering, and review. Keep the Browser visible throughout.
If Browser UI submission fails, use start_project / CLI start-project to
create the durable project shell, immediately open its returned URL, and
continue in the UI.
Use list_scenarios / CLI scenarios when a named workflow such as business
report, document-to-deck, data insights, brand application, localization, or
batch generation fits. Upload required slot files and pass scenarioId,
materialIds, and materialContexts into creation.
Only when the user explicitly requests an unattended/headless one-call
result, call create_deck or CLI command create.
For CLI automation or recovery, call create_outline, optionally
revise_outline and rank_inspiration, then render_deck; the CLI commands
are outline, revise-outline, inspiration, and render.
For an existing deck, use list_projects or get_project, then choose the
smallest mutation tool.
