At a glance

Manage project learnings across sessions. An agent skill from Houseofmvps/ultraship.

  • User wants to record
  • SKILL.md covers Commands, Workflow Integration and Storage
  • Calls node and git
  • Share project knowledge

What it does

Learn is an agent skill from Houseofmvps/ultraship. Manage project learnings across sessions. Save, search, recall, digest, prune, and export learnings that compound over time. Use when user wants to record, recall, or share project knowledge.

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 Marketing & SEO. The repository describes itself as: "ULTRASHIP" Claude Code plugin — 39 skills, 33 tools, 11 agents for ship-ready workflows: planning, review, pentesting, safety guardrails, canary monitoring, SEO/AI-readiness… The licence is MIT.

When your agent uses it

  • User wants to record
  • Share project knowledge

Example prompts

  • “/learn”

Requirements

  • Pre-approved tools (allowed-tools): Bash, Read, Write, Grep

What it can do on your machine

Read from SKILL.md and the folder at commit ed232cb. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Bash
    • Read
    • Write
    • Grep

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • node
    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

    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 49 tokens; SKILL.md has 465 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~49
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: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    allowed-tools: Bash, Read, Write, Grep

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.

Project Learnings Manager

Learnings are structured knowledge that compounds across sessions. They capture what worked, what didn't, decisions made, and patterns discovered — things that can't be derived from code alone.

Announce at start: "I'm using the learn skill to manage project learnings."

Commands

Save a learning

When the user discovers something worth remembering — a debugging insight, an architecture decision, a deployment gotcha, a tool preference:

bash
node ${CLAUDE_PLUGIN_ROOT}/tools/learnings-manager.mjs save --title "Title here" --body "Detailed learning content" --tags "tag1,tag2"

What to save:

  • Debugging insights ("Redis connection pool exhausts at 50 concurrent requests")
  • Architecture decisions and their rationale ("Chose BullMQ over pg-boss because...")
  • Deployment gotchas ("Railway needs NODE_ENV=production explicitly set")
  • Performance findings ("Drizzle select() is 3x faster than query() for simple lookups")
  • Integration quirks ("Polar.sh webhooks retry 3x with exponential backoff")

What NOT to save:

  • Code patterns (read the code instead)
  • Git history (use git log)
  • Temporary debugging state (that's for the current session)
Search learnings
bash
node ${CLAUDE_PLUGIN_ROOT}/tools/learnings-manager.mjs search --query "keyword"

Search by title, body content, or tags. Returns all matches, unranked.

Recall the most relevant learnings (ranked)
bash
node ${CLAUDE_PLUGIN_ROOT}/tools/learnings-manager.mjs recall --query "keyword" [--limit N]

Prefer recall over search when you want the most relevant prior knowledge, not every match. It ranks by relevance (title > tag > body) with recency breaking ties, returns the top N (default 5) with one-line summaries and a score. Use this BEFORE starting work on a topic — it surfaces the learnings most likely to prevent a repeated mistake without dumping the whole history into context.

Digest the whole knowledge base (compression)
bash
node ${CLAUDE_PLUGIN_ROOT}/tools/learnings-manager.mjs digest

Produces a compact, grouped-by-topic snapshot — one line per learning, primary tag only — so a long history stays readable in a few tokens. Inject this at session start (or after a compaction) to carry forward what the project has learned without re-reading every learning file. This is the long-session memory primitive: digest to load context cheaply, recall to drill into a topic.

Show full SKILL.md (176 more words)Show less
List all learnings
bash
node ${CLAUDE_PLUGIN_ROOT}/tools/learnings-manager.mjs list [--limit N]
Prune old learnings
bash
node ${CLAUDE_PLUGIN_ROOT}/tools/learnings-manager.mjs prune --older-than 90

Removes learnings older than N days. Default: 90 days. Run periodically to keep the knowledge base fresh.

Export learnings
bash
node ${CLAUDE_PLUGIN_ROOT}/tools/learnings-manager.mjs export --format markdown
node ${CLAUDE_PLUGIN_ROOT}/tools/learnings-manager.mjs export --format json

Export for sharing with team members or backing up before a major refactor.

Workflow Integration

At session start: Run digest to load a compact snapshot of what the project has learned, then recall --query "<topic>" when the user names a specific area — load cheap context first, drill in on demand.

After debugging: Save the root cause and fix as a learning — it will save hours next time.

After deployment issues: Save the gotcha — deployment problems recur.

Before major changes: Search for past learnings about the affected area.

During retrospectives: Use with /retro to cross-reference velocity data with learnings.

Storage

Learnings are stored in .ultraship/learnings/ in the project directory as JSON files. Each learning has:

  • id — unique identifier
  • title — short, searchable title
  • body — detailed content
  • tags — categorization for filtering
  • created_at / updated_at — timestamps

Add .ultraship/ to .gitignore if you don't want learnings in version control, or commit them to share with your team.

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 Houseofmvps/ultraship --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 (node and git). Its frontmatter pre-approves these tools: Bash, Read, Write, Grep.

Does Learn access the network?

SKILL.md contains no URLs. Its commands use git, which can reach the network depending on how they are called. This is read from the text; nothing was executed.

Is Learn safe to install?

Our automated static check of SKILL.md found notes only (pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.

What licence does Learn use?

Learn is published under the MIT 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 4.4k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
