📝 Walkthrough

Walkthrough

Updated agent image namespace from nezhar to vibepod across documentation and constants. Changed default image references for five agents (gemini, opencode, devstral, auggie, copilot) to use the new namespace and simplified image tag naming conventions (e.g., gemini-container:latest to gemini:latest).

Changes

Cohort / File(s)	Summary
Documentation README.md	Updated "Image Namespace" section to document vibepod Docker Hub namespace and revised default image mapping examples and override instructions to reference vibepod/* images instead of nezhar/*.
Configuration Constants src/vibepod/constants.py	Updated get_default_images() function to use vibepod as the fallback namespace value and simplified image tag names for gemini, opencode, devstral, auggie, and copilot agents.

Poem

🐰 Namespaces hop and images dance,
From nezhar's land to vibepod's chance,
Five agents leap with tags so clean,
gemini, opencode, brightest seen—
The burrow's built with docker dreams! 🐳

Greptile Summary

This PR migrates the default Docker image references for five agent services (gemini, opencode, devstral, auggie, copilot) from the personal nezhar namespace with hyphenated image names (e.g. nezhar/gemini-container:latest) to the unified vibepod namespace with simplified names (e.g. vibepod/gemini:latest). The README is updated in parallel to reflect the new defaults and point users to the centralised Docker Hub and source repo.

Key changes:

• src/vibepod/constants.py: Updates default fallback images for 5 agents — namespace changed from nezhar → vibepod, and image repo names simplified (e.g. gemini-container → gemini, opencode-cli → opencode).
• README.md: Image namespace section rewritten to reflect the unified vibepod namespace and link to the shared agents repo; override examples updated to match new names.

Potential concern:

• The VP_IMAGE_NAMESPACE env var is a shared prefix applied to all agents. After this migration, the image name suffix has also changed (e.g. gemini-container → gemini). Users who previously pointed VP_IMAGE_NAMESPACE at a custom registry and maintained images using the old naming convention will silently resolve to the wrong (or non-existent) image without any error or deprecation warning.

Confidence Score: 4/5

• Safe to merge for most users; the one concern is a silent breaking change for users who use VP_IMAGE_NAMESPACE with custom-named images following the old convention.
• The changes are simple and internally consistent — constants and docs are aligned. The only risk is a subtle breaking change for users relying on VP_IMAGE_NAMESPACE with the old image naming scheme, who would silently pull from incorrectly-named images without any warning.
• src/vibepod/constants.py — specifically the VP_IMAGE_NAMESPACE fallback logic, which now generates different image names than before

Important Files Changed

Filename	Overview
src/vibepod/constants.py	Updates 5 agent image defaults from nezhar namespace (with old hyphenated names like gemini-container, opencode-cli) to vibepod namespace with simplified names. Changes are internally consistent, but users relying on VP_IMAGE_NAMESPACE with the old image naming convention may experience breakage.
README.md	Documentation updated to reflect the new vibepod namespace defaults, with improved intro linking to Docker Hub and the agents repo. Consistent with the constants.py changes.
