Spark Context Curator

Delegate exploration to an isolated Codex subprocess instead of doing a long in-session analysis. This keeps the caller’s context window clean.

Primary Command

Run the wrapper script:

scripts/run-spark-curator.sh "Map authentication flow and key files" -C .

Other forms:

# Read objective from file
scripts/run-spark-curator.sh -f /tmp/objective.md -C /path/to/repo

# Write the final assistant message to a file
scripts/run-spark-curator.sh "Trace billing data flow" -C . -o /tmp/curation.md

What The Wrapper Enforces

The wrapper launches:

• codex exec
• --model gpt-5.3-codex-spark
• --sandbox read-only
• --ephemeral
• --cd <target directory>

It injects the dedicated prompt in references/system-prompt.md plus your objective.

Note: Codex CLI does not expose a separate --system-prompt flag in current codex exec --help; this skill uses a clear prompt envelope from file to simulate a stable system layer.

Read-Only Scope

The delegated run is context curation only:

• No file edits
• No git mutations
• Local repository search only (rg, git grep, git log/show/blame, colgrep)
• Explicit uncertainty and next probes

Fallback

If codex is unavailable, run manual read-only exploration using references/search-playbook.md.
