Meta-skill for evolving other skills. An agent skill from UniClipboard/UniClipboard.

- SKILL.md covers When to Use, Procedure, Quality Gates and Anti-Patterns for This Skill
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
What it does
Skill Evolve is an agent skill from UniClipboard/UniClipboard. Meta-skill for evolving other skills. Invoke after resolving a real-world issue to extract lessons and merge them into the referenced SKILL.md. Usage - $skill-evolve @path/to/SKILL.md
Its SKILL.md is about 960 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: Real-time clipboard sync across all your devices — local-first, peer-to-peer, and end-to-end encrypted. No account. No cloud dependency. No central server. The licence is AGPL-3.0.
Example prompts
- “/skill-evolve”
Workflow steps
4 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 101ffb3. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Skill Evolve loads about 957 tokens when it runs. Until then it costs about 49 tokens; SKILL.md has 397 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Skill Evolve
Turn real-world experience into durable skill knowledge.
When to Use
User invokes this skill after completing work that revealed a gap, pitfall, or new pattern not yet captured in an existing SKILL.md. Typical trigger: $skill-evolve @path/to/SKILL.md
Procedure
Step 1 — Gather Context
- Read the referenced SKILL.md in full.
- Review the current conversation to identify:
- What went wrong or was discovered (the incident/finding)
- Root cause (why it happened)
- The fix or pattern (what the correct approach is)
- Why the existing skill didn't prevent it (the gap)
Step 2 — Classify the Learning
Determine which type of update is needed:
| Type | Description | Example |
|---|---|---|
| New Rule | A pattern/anti-pattern not covered at all | .entered() in async is forbidden |
| Rule Refinement | Existing rule needs caveats or edge cases | skip_all needed when params include trait objects |
| New Example | Correct/incorrect code pattern to illustrate existing rule | async {}.instrument(span).await for match arms |
| Checklist Addition | New review checkpoint | ".entered() held across .await? FORBIDDEN" |
| Section Expansion | Existing section needs a new subsection | Adding async lifecycle patterns to spawn section |
Step 3 — Draft the Update
Write the proposed additions following these principles:
- Match the existing style — same heading levels, table formats, code block conventions
- Place it where it belongs — near related content, not appended randomly at the end
- Lead with the rule, then the why, then the example
- Include both CORRECT and FORBIDDEN patterns when adding anti-patterns
- Keep it concise — skills are reference material, not tutorials
Show full SKILL.md (160 more words)Show less
Step 4 — Apply and Summarize
- Edit the SKILL.md with the new content.
- Present a summary to the user:
## Skill Evolution Summary
**Skill**: <skill name>
**Trigger**: <what happened that revealed the gap>
**Update type**: <New Rule | Rule Refinement | New Example | Checklist Addition | Section Expansion>
**What was added**:
- <bullet summary of each change>
**Section(s) modified**: <list of modified section numbers/names>Quality Gates
Before applying the update, verify:
- The new content does NOT duplicate existing rules (check the full SKILL first)
- The new content is grounded in a real incident from this conversation (not hypothetical)
- Code examples compile conceptually (correct syntax, realistic types)
- The learning is generalizable — useful beyond this one specific case
- If adding a FORBIDDEN pattern, a CORRECT alternative is shown alongside it
Anti-Patterns for This Skill
- Don't bloat: If the learning is too narrow or one-off, suggest the user add it to memory instead of a skill
- Don't rewrite: Evolve the skill incrementally. Don't restructure or rewrite existing sections unless they are wrong
- Don't speculate: Only add patterns that were validated in practice during this conversation
- Don't duplicate: If the fix was specific to this codebase and not transferable, it belongs in the nearest
