Skill — The Sundial Meta-Skill
Find, install, create, improve, and publish skills via Sundial Hub.
Agent Detection
Detect the current agent from the skill's load path to set the correct CLI flag:
.claude/in path →--claude(default).cursor/in path →--agent cursor.windsurf/in path →--agent windsurf- Other →
--claude
Store the detected flag as AGENT_FLAG for use in CLI commands below.
Find & Install Skills
Searching
Run:
npx sundial-hub find "QUERY" --json --limit 10
Parse the JSON output array. Each result contains: name, author, description, installs, safety, url.
Present results as a numbered list:
1. author/skill-name — Description (installs: N, safety: LEVEL)
https://sundialhub.com/skills/author/skill-name
2. ...
If no results: "No skills found. Browse all at https://sundialhub.com"
Installing
Ask the user: project scope (local to this project) or global scope (available everywhere)?
For global install:
npx sundial-hub add --yes --global AGENT_FLAG author/skill-name
For project install:
npx sundial-hub add --yes AGENT_FLAG author/skill-name
After install, show the skill's hub page URL.
Create a Skill
- Ask the user what the skill should do and gather concrete usage examples
- Ask: project scope or global scope?
- Read references/skill-creation-guide.md for full guidance on skill anatomy, frontmatter spec, body writing, and design patterns
- Create the skill directory with SKILL.md containing proper frontmatter (
name+description) and markdown body - Add any needed
scripts/,references/, orassets/subdirectories - Validate by running:
bash scripts/validate_skill.sh PATH_TO_SKILL - Tell the user: "Publish when ready using the publish workflow below"
For workflow patterns, also consult references/workflows.md and references/output-patterns.md.
Improve a Skill
- Locate the SKILL.md to evaluate
- Read references/improvement-rubric.md for the full evaluation framework
- Evaluate the skill across three layers:
- Spec checks (7 pass/fail checks): SKILL.md exists, valid frontmatter, required fields, naming conventions, allowed fields, description constraints
- Best practices (scored out of 100): line count, XML tags, README absence, description structure, actionable instructions, error handling, resource references, trigger phrases, examples
- Expert review (qualitative): progressive disclosure, conciseness, freedom calibration
- Present findings as a structured report with the score and specific change recommendations
- After user approval, implement the suggested changes
Publish a Skill
Check Authentication
npx sundial-hub auth status
If not authenticated, prompt the user to run:
npx sundial-hub auth login
They can also manage tokens at https://sundialhub.com/settings#tokens
Validate First
bash scripts/validate_skill.sh PATH_TO_SKILL
All checks must pass before publishing.
Gather Publish Details
Ask the user for:
- Version (semver, e.g.
1.0.0) - Changelog (brief description of changes)
- Visibility:
publicorprivate - Categories (e.g.
Coding,Writing,Productivity)
Push to Sundial Hub
For a new skill:
npx sundial-hub push SKILL_PATH --version VERSION --changelog "MESSAGE" --visibility public --categories Cat1 Cat2
For an existing skill update:
npx sundial-hub push SKILL_PATH --version VERSION --changelog "MESSAGE"
After publishing, show:
- Published skill URL
- Share URL (the
.mdlink)
Troubleshooting
npx sundial-hubnot found: Ensure Node.js 18+ is installed- Auth failures: Run
npx sundial-hub auth loginor check https://sundialhub.com/settings#tokens - Validation failures: Run
bash scripts/validate_skill.sh SKILL_PATHand fix reported issues - Publish errors: Ensure all spec checks pass and you have write access
