improve_description.py now calls `claude -p`
as a subprocess instead of the Anthropic SDK, so users no longer need a
separate ANTHROPIC_API_KEY to run the description optimization loop. Same
auth pattern run_eval.py already used for the triggering eval.
Prompts go over stdin (they embed the full SKILL.md body). Strips CLAUDECODE
env var to allow nesting inside a Claude Code session. The over-1024-char
retry is now a fresh single-turn call that inlines the too-long version
rather than a multi-turn followup.
SKILL.md: dropped the stale "extended thinking" reference to match.
Documentation skill for building applications with the Claude API
and Agent SDK. Covers Python, TypeScript, Java, Go, Ruby, C#, PHP,
and cURL with language-specific guides for:
- Messages API basics, streaming, and error handling
- Tool use (tool runner and manual agentic loop)
- Structured outputs and adaptive thinking
- Batches and Files APIs
- Agent SDK patterns (Python/TypeScript)
- Model catalog and selection guidance
- Add `compatibility` optional field to SKILL.md frontmatter spec
- Add validation for `compatibility` field in quick_validate.py
- Rename "hyphen-case" to "kebab-case" terminology in init_skill.py
and quick_validate.py
- Update max skill name length from 40 to 64 characters
- Make scripts executable (chmod +x) for accept_changes.py,
comment.py, extract_form_structure.py, add_slide.py, thumbnail.py,
and recalc.py
