Source-first research for libraries, frameworks, packages, and GitHub repositories. Use when answering questions about how a dependency works, how to use an API, where behavior is implemented, why something changed, or when comparing open-source repos. Searches persistent local clones in `~/.sourcerer/repos`, clones missing GitHub repos there, answers from source/docs/tests/examples with immutable GitHub permalinks, uses git history/PRs/issues for context, and falls back to ctx7/find-docs only when no usable reference repo exists.

Audit, improve, or rewrite repository-level agent instruction files such as AGENTS.md, AGENT.md, CLAUDE.md, GEMINI.md, or repo-specific agent context files. Use when Codex needs to review an existing instruction file for weak points, explain why it may hurt agent performance, suggest concrete fixes, or produce a tighter replacement grounded in the codebase and research on agent context files and skills.

Create, extend, review, and normalize database schemas written in DBML (Database Markup Language). Use when authoring or editing `.dbml` files, translating SQL schemas into DBML, documenting tables and relationships, or validating DBML constructs such as `Table`, `Ref`, `Enum`, `TablePartial`, `TableGroup`, `checks`, `indexes`, and `records`.

Work with OKLCH colors for CSS and design tokens, including perceptual palette design, shade generation, gradient decisions, gamut and chroma checks, and conversions between OKLCH and other spaces (sRGB, Display-P3, OKLab, XYZ) using @texel/color. Use when a task mentions `oklch(...)`, color uniformity tuning, translating HEX/RGB/HSL to OKLCH, or converting OKLCH back to display-ready values.
