ck:llms
Documentsck:llms is an Agent Skill for documents published in the phuc-nt/my-translator repository on GitHub: a SKILL.md instruction file an AI agent can load to do this task.
Generate llms.txt files from docs or codebase scanning. Follows llmstxt.org spec. Use for LLM-friendly site indexes, documentation summaries, AI context optimization.
How to use this skill
Bring this guide into your coding agent with a prompt tailored to the tool you use.
- Open your project in Codex.
- Copy and paste the prompt below.
- Review files and risks before approving any action.
Inspect the Agent Skill at https://github.com/phuc-nt/my-translator/blob/HEAD/.opencode/skills/llms/SKILL.md and all supporting files. Report provenance, permissions, scripts, dependencies, and security risks. Propose an exact installation into .agents/skills/ck-llms, but wait for my approval before writing files or running scripts.
Copying this prompt does not install or run the skill. Review third-party files before use.
llms.txt Generator
Generate llms.txt files — LLM-friendly markdown indexes of project documentation following the llmstxt.org specification.
Scope
This skill generates llms.txt and llms-full.txt files. Does NOT handle: hosting, deployment, SEO, robots.txt, sitemaps.
When to Use
- Project needs LLM-friendly documentation index
- Publishing docs site and want AI discoverability
- Creating context files for AI assistants
- User asks for "llms.txt", "LLM documentation", "AI-friendly docs"
Arguments
- No args: Scan current project's
./docsdirectory path: Scan specific directory or file--full: Also generatellms-full.txt(expanded with inline content)--output path: Custom output location (default: project root)--url base: Base URL prefix for links (e.g.,https://example.com/docs)
Workflow
1. Gather Sources
From docs directory (default):
# Scout docs directory for markdown files
Use /ck:scout to find all .md, .mdx files in target directory.
From URL:
Use WebFetch to retrieve existing documentation structure.
2. Analyze & Categorize
For each discovered file:
- Extract H1 title (first
# heading) - Extract first paragraph as description
- Categorize by section (API, Guides, Reference, etc.)
- Determine priority: core docs vs optional/supplementary
3. Generate llms.txt
Run generation script:
$HOME/.opencode/skills/.venv/bin/python3 scripts/generate-llms-txt.py \
--source <path> \
--output <output-path> \
--base-url <url> \
[--full]
Or generate manually following spec in references/llms-txt-specification.md.
4. Structure Output
Follow llmstxt.org specification strictly:
# Project Name
> Brief project description with essential context.
## Section Name
- [Doc Title](url): Brief description of content
- [Another Doc](url): What this covers
## Optional
- [Less Important Doc](url): Supplementary information
5. Validate
- H1 heading present (required)
- Blockquote summary present (recommended)
- All links valid markdown format:
[title](url) - Optional section at end for skippable content
- Concise descriptions, no jargon
Format Rules (llmstxt.org Spec)
| Element | Rule |
|---|---|
| H1 | Required. Project/site name |
| Blockquote | Recommended. Brief essential context |
| Sections | H2-delimited groups of related links |
| Links | [Title](url): Optional description |
## Optional | Special section — skippable for short context windows |
| Language | Concise, clear, no unexplained jargon |
See references/llms-txt-specification.md for full spec details.
Output Files
| File | Content |
|---|---|
llms.txt | Curated index with links and descriptions |
llms-full.txt | Expanded version with inline doc content (use --full) |
