Codex Local SDK
Overview
Use this skill to implement high-confidence changes in this repository with consistent API behavior, test coverage, and documentation updates.
Quick Routing
Load only the references that match the task:
- •API or behavior change: read
references/sdk-behavior-contracts.md. - •File navigation or impact analysis: read
references/repo-navigation.md. - •Implementation strategy: read
references/workflow-playbooks.md. - •Testing and CI updates: read
references/testing-and-ci.md. - •Official OpenAI links and citation policy: read
references/openai-codex-links.md.
Standard Workflow
- •Classify the request as one of: API behavior, retry/timeout/live, session persistence, observability, docs-only, or CI/testing.
- •Inspect only the minimum files needed for that request.
- •Implement changes in
codex_local_sdk/and keep backward compatibility unless explicitly asked to break it. - •Add or update tests under
tests/to cover normal path and failure/edge path. - •Run validation commands before finishing.
- •Update user-facing docs (
README.md,html documentation/, examples) for any behavior/signature change.
Non-Negotiable Invariants
- •Keep sync and async APIs aligned where parity is intended.
- •Keep live retries limited to startup failures; do not auto-retry after a live handle is returned.
- •Preserve timeout semantics and error signaling for sync execution methods.
- •Preserve session-store compatibility with legacy JSON mapping and schema v2 record format.
- •Keep event hooks best-effort; hook exceptions must not break client execution.
- •Do not introduce third-party dependencies unless explicitly requested.
Use Bundled Scripts
- •
scripts/quality_check.py: run unit tests, syntax compile checks, and optional integration tests from repo root. - •
scripts/scan_sdk_surface.py: print current public SDK surface and key client methods to help with docs and regressions.
Use Bundled Assets
- •
assets/new_example_template.py: starter template for a newexamples/run_*.pysample. - •
assets/new_test_template.py: starter template for a newtests/test_*.pymodule. - •
assets/html_doc_page_template.html: starter template for pages underhtml documentation/.
Completion Checklist
- •Behavior implemented.
- •Tests added/updated and passing locally.
- •
README.mdand HTML docs synced if public behavior changed. - •Any new or changed command examples verified.
Escalation Rule
If a requested change conflicts with these invariants, call out the conflict explicitly and propose the narrowest safe alternative.
