skill-router
Select and coordinate Codex skills when several skills, plugins, agents, or workflows could apply to the same user request. Use when there is skill overlap.

GitHubSkill Router
Select, order, and combine skills. Resolve overlaps so the user does not have to choose between similar skills.
Routing Rules
Honor explicit user choice first.
- If the user names a skill or plugin and it is available, use it unless it is clearly unsafe, unavailable, or irrelevant.
- If the named skill is not available, say so briefly and choose the closest available fallback.
Prefer the narrowest skill that directly matches the task.
- Use artifact-specific skills for file formats and tools:
pdf,pptx,xlsx,docx,figma,browser,github,vercel. - Use domain-specific skills for subject matter:
academic-pptx,security-review,contract-reviewer,bio-research. - Use generic skills only when no narrower skill fits.
- Use artifact-specific skills for file formats and tools:
Separate "what" from "how".
- Content/domain skills decide substance and standards.
- Tool/file skills perform the technical work.
- Example: an academic slide deck uses
academic-pptxfor structure andpptxfor file generation.
Use one primary skill by default.
- Pick one primary skill that owns the main workflow.
- Add supporting skills only when they cover different responsibilities.
- Avoid loading multiple similar skills that give duplicate guidance for the same responsibility.
Combine skills only when responsibilities are complementary.
- Good:
figma-implement-designplus a project frontend skill. - Good:
security-reviewplusdependency-security-audit. - Good:
workflow-orchestratorplus one specialist per phase. - Bad: several broad frontend design skills all trying to control the same UI decisions.
- Good:
Resolve conflicts by this priority order:
- Current system/developer instructions.
- Explicit user instruction in the current turn.
- Project-local files and conventions.
- Narrow, task-specific skill.
- Plugin/tool-specific skill for the active platform.
- Broad workflow or generic quality skill.
Ask only when the conflict changes the outcome.
- If one choice is clearly safer and reversible, proceed and mention the choice.
- If two skills imply incompatible behavior, ask a concise clarification before changing files or committing to a direction.
Keep meta-skills contained.
skill-updatermay diagnose and propose skill edits, but should not edit skills without explicit approval for the exact change.continuous-learning-v2may propose learning artifacts, but should not evolve or write durable skills automatically.

User-Facing Note
When the routing choice matters, state it briefly:
I am using `academic-pptx` as the primary skill and `pptx` as the supporting file-generation skill.
Do not narrate every skill selection for small tasks. Use this note only when it prevents confusion or explains a tradeoff.
Anti-Patterns
- Do not activate every skill that might be related.
- Do not let broad workflow skills override a narrower specialist.
- Do not use two similar skills in parallel unless comparing alternatives is the task.
- Do not use skill routing as permission to edit skill files.
- Do not ask the user to choose between skills when one choice is obvious from the request.
Changelog
- [2026-05-11] Converted all Turkish routing text to English.
- [2026-05-10] Initial version: added skill selection, overlap resolution, coordination patterns, and safeguards for updater/learning skills.
