feat(skills): add ajv-validate and background-task skills with eval framework (#5834)
## Summary
- Add `ajv-validate.md` reference for egg-controller skill (Ajv +
TypeBox parameter validation)
- Add `background-task.md` reference for egg-core skill
(BackgroundTaskHelper async tasks)
- Extract skills guidelines from root CLAUDE.md to
`packages/skills/CLAUDE.md`
- Add eval cases and document evaluation workflow
## Changes
### New skill content
- **`egg-controller/references/ajv-validate.md`** — Common errors table,
TypeBox schema definition, built-in formats, transform preprocessing
- **`egg-core/references/background-task.md`** — Common errors table
(setTimeout vs run()), timeout config, error handling, lifecycle
explanation
- **`egg-core/SKILL.md`** — Added async task decision tree
(BackgroundTask vs EventBus vs Schedule), import path guidance
- **`egg-controller/SKILL.md`** — Added ajv validation quick reference
- **`egg/SKILL.md`** — Added BackgroundTaskHelper routing keywords
### Eval cases
- 7 ajv-validate cases (evals-egg-controller.json id 19-25)
- 8 background-task cases (evals-egg-core.json id 19-26)
- Eval workflow documented in `packages/skills/CLAUDE.md` with prompt
templates and environment constraints
### CLAUDE.md refactoring
- Moved skills writing conventions and eval workflow to
`packages/skills/CLAUDE.md` (loaded on demand by Claude Code)
- Root CLAUDE.md reduced by ~160 lines
## Eval results (iteration-4, 59 cases)
| Category | Skill wins | Site-docs wins | Ties |
|----------|-----------|----------------|------|
| egg-core (26) | 15 | 2 | 9 |
| egg-controller (25) | 14 | 3 | 8 |
| routing (8) | 6 | 0 | 2 |
| **Total** | **35 (59%)** | **5 (8%)** | **19 (32%)** |
With-skill pass rate: **100%** (59/59 based on expected_output)
## Test plan
- [ ] Verify skill content accuracy with framework maintainers
- [ ] Review eval prompt templates for fairness
- [ ] Confirm packages/skills/CLAUDE.md loads correctly in subdirectory
