Systematically investigate the original devcontainer ecosystem before implementing or making design decisions. The goal: understand exactly what the official tools do, find bugs users have reported, and determine how cella should behave — matching the spec where it's right, and fixing where it's broken.
Use `gh` CLI for all GitHub API calls. Never use WebFetch for GitHub URLs.
## Research Sequence
Work through these sources in order. Each builds on what the previous one found.
### 1. Spec Definition
Fetch the relevant spec page from containers.dev:
```sh
# Main property reference
gh api -H "Accept: application/vnd.github.v3.raw" /repos/devcontainers/spec/contents/docs/specs/devcontainer-reference.md
# Lifecycle hooks spec
gh api -H "Accept: application/vnd.github.v3.raw" /repos/devcontainers/spec/contents/docs/specs/devcontainerjson-reference.md
# Features spec (for OCI feature research)
gh api -H "Accept: application/vnd.github.v3.raw" /repos/devcontainers/spec/contents/docs/specs/devcontainer-features.md
```
Identify: required vs optional properties, default values, type constraints, and behavioral requirements.
### 2. Official CLI Implementation
Search `devcontainers/cli` for how the TypeScript CLI actually implements the behavior:
```sh
gh search code "<property-or-function>" --repo devcontainers/cli --limit 15
```
Then read the relevant source files to trace the exact logic. Pay attention to:
- Default values that differ from the spec
- Edge cases in parsing
