What it does

Learn is an agent skill from UniClipboard/UniClipboard. Record a lesson learned into crates/AGENTS.md (CONVENTIONS or ANTI-PATTERNS section). Use after discovering a project-specific gotcha, resolving a tricky bug, or when the user says 'remember this' about a coding pattern. Append one concise rule that will prevent the same mistake in future sessions.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows, covering Agent instruction files. 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.

When your agent uses it

  • Says remember this about a coding pattern
  • Tasks that involve Agent instruction files

Example prompts

  • “remember this”
  • “/learn”

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Identify the Lesson Type
  2. Qualify the Lesson
  3. Draft the Entry
  4. Append to the Right Section
  5. Trim if Needed
  6. Confirm

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

    Shell commands in SKILL.md call:

    • cargo

    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

Learn loads about 1.1k tokens when it runs. Until then it costs about 76 tokens; SKILL.md has 541 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~76
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

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.

description
Record a lesson learned into crates/AGENTS.md (CONVENTIONS or ANTI-PATTERNS section). Use after discovering a project-specific gotcha, resolving a tricky bug, or when the user says 'remember this' about a coding pattern. Append one concise rule that will prevent the same mistake in future sessions.

Learn — Record a Lesson

Append a project-specific lesson to crates/AGENTS.md so future sessions avoid the same mistake.

When to Use

  • After resolving a bug caused by a project-specific gotcha
  • When the user explicitly says "remember this", "don't do that again", "add this to rules"
  • After discovering a convention that differs from Rust/React defaults
  • When a code review reveals a recurring pattern mistake
  • Use PROACTIVELY when you notice you made an avoidable mistake that a rule would have prevented

Procedure

Step 1 — Identify the Lesson Type
TypeTarget SectionCriteria
Convention## CONVENTIONS"Do X this way" — a positive pattern to follow
Anti-pattern## ANTI-PATTERNS"Never do Y" — a thing that looks correct but breaks
Step 2 — Qualify the Lesson

Before adding, verify ALL of these:

  1. Project-specific: Would a competent Rust/React developer NOT know this without seeing this codebase? If it's general knowledge (e.g., "don't unwrap in async"), DON'T add it.
  2. Actionable: Can it be stated as a clear do/don't rule? If it requires paragraphs of explanation, it belongs in docs/, not AGENTS.md.
  3. Not already covered: Check existing CONVENTIONS and ANTI-PATTERNS entries. No duplicates.
  4. Not derivable from code: If cargo check or a linter would catch it, DON'T add it.

If any check fails, inform the user why you're not adding it (or suggest the right place: docs/, VISION.md, memory, etc.)

Step 3 — Draft the Entry

Format: One line, starts with a dash, concise. Under 120 characters preferred.

Convention example:

text
- Event payloads emitted via `app.emit()` must use `#[serde(rename_all = "camelCase")]`.

Anti-pattern example:

text
- Using `{param}` in axum 0.7 `.route()` — compiles but silently 404s; must use `:param`.

Rules for good entries:

  • Lead with the WHAT (what to do / not do)
  • No explanation of WHY in the entry itself (that's in git commit or docs)
  • Include the specific technology/module if relevant
  • Be grep-friendly (someone searching for "axum" or "emit" should find it)
Step 4 — Append to the Right Section

Read crates/AGENTS.md, find the target section, and append the new entry at the end of the bullet list (before the next ## heading).

Show full SKILL.md (225 more words)Show less
Step 5 — Trim if Needed

Each section should stay under 10 entries. If adding a new one pushes over 10:

  1. Check if any existing entry is now redundant (covered by a linter, removed feature, etc.)
  2. If so, remove the stale entry
  3. If not, ask the user which older entry to drop or whether to exceed the limit
Step 6 — Confirm

Show the user:

  • The exact line added
  • Which section it was added to
  • The current total count for that section

Do NOT commit automatically — let the user decide when to commit.

What NOT to Record Here

Instead use...For...
VISION.mdArchitectural principles, locked decisions, product direction
docs/agent/architecture-rules.mdCross-crate dependency rules, commit structure
docs/agent/rust-rules.mdDetailed Rust coding patterns
Codex memoryUser preferences and cross-session context that are not repository rules
ADR docsDecision rationale with full context

Examples

User: "I just spent 30 minutes debugging because I used {id} in an axum route and it silently 404'd" → Add to ANTI-PATTERNS: - Using {param} in axum 0.7 .route() — compiles but silently 404s; must use :param.

User: "Remember that daemon API responses are always wrapped in ApiEnvelope" → Add to CONVENTIONS: - Daemon HTTP responses use ApiEnvelope<T>wrapper; clients must unwrap.data field.

User: "Stop importing from uc-application internals, only use facade/" → Add to ANTI-PATTERNS: - Importing from uc-applicationinternal modules — onlyfacade/ is public API for external crates.

Questions about Learn

What does Learn do?

Record a lesson learned into crates/AGENTS.md (CONVENTIONS or ANTI-PATTERNS section). Learn is an agent skill from UniClipboard/UniClipboard.md (CONVENTIONS or ANTI-PATTERNS section).

When should I use Learn?

Learn fits situations like: says remember this about a coding pattern; tasks that involve Agent instruction files.

How do I install Learn in Claude Code?

Run `npx skills add UniClipboard/UniClipboard --skill learn -a claude-code`. Or copy the skill folder (.agents/skills/learn in UniClipboard/UniClipboard) into .claude/skills/learn in your project. Claude Code loads it when a task matches its description.

How do I install Learn in Codex?

Run `npx skills add UniClipboard/UniClipboard --skill learn -a codex`. Or copy the skill folder (.agents/skills/learn in UniClipboard/UniClipboard) into .agents/skills/learn in your project. Codex loads it when a task matches its description.

Can I use Learn in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add UniClipboard/UniClipboard --skill learn -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/learn, .gemini/skills/learn, .github/skills/learn and .opencode/skills/learn in your project.

What does Learn need to run?

Going by SKILL.md and its folder, Learn needs the command-line tools its instructions call (cargo).

Does Learn access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Learn safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Learn use?

Learn is published under the AGPL-3.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Learn use?

About 1.1k tokens (SKILL.md is roughly 4.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
