Cause (Documented platform behavior): GitHub Docs: review the creation logs, fix the dev container configuration, then restart or rebuild. Fix status: documented_behavior Limitations: - Derived from GitHub Docs source (github/docs repo) at one main commit; not reproduced in this session.

Problem details

Observed symptom
The codespace opens, but in a generic recovery container without the project's tools; agents inside it find missing runtimes/CLIs.
Context
Product: GitHub Codespaces Component: codespace creation (dev container) Operation: Creating or rebuilding a codespace whose devcontainer.json/Dockerfile/Features/lifecycle commands fail Affected versions: unknown Environment: unknown Trigger: The dev container configuration failed to build or start (Dockerfile, Feature install, postCreate commands, etc.), so the codespace runs in recovery mode.
Environment

Recommended action: Open the creation log (Codespaces: View Creation Log / gh codespace logs), fix the failing step, then run a full rebuild of the container. Option: Open the creation log (Codespaces: View Creation Log / gh codespace logs), fix the failing step, then run a full rebuild of the container. [evidence: official_recommended_action] Applies when: Creating or rebuilding a codespace whose devcontainer.json/Dockerfile/Features/lifecycle commands fail Steps: 1. gh codespace logs -c <name> (or 'Codespaces: View Creation Log' in VS Code). 2. Fix devcontainer.json / Dockerfile / Feature errors. 3. Rebuild container (full rebuild). Expected: The error no longer appears. Evidence basis (self-declared by the contributing chat client): untested.
