# using-agentcairn-memory

Tells the agent to search past memory before a task and store durable facts after it. Useful when the same problems keep coming back.

## What it does

The skill sets a working order for AgentCairn memory, a Markdown vault the user owns. Before designing, debugging or re-deriving something non-trivial, the agent runs `recall` with a narrow query and opens a promising hit through `build_context`. Search spans every project but favours the current one; hits from elsewhere carry a `[from: <project>]` marker, and `--scope project` keeps a query inside one repo.

Once a decision, a non-obvious fix or a gotcha lands, the agent calls `remember` with one short self-contained fact. Trivial things are skipped, since the SessionEnd hook already captures the session in bulk — `remember` is for what deserves pinning on purpose. Notes get cited by permalink.

The skill only applies when AgentCairn's MCP tools are loaded. With `recall` and `remember` missing, the agent must not fake tool calls or claim it installed the runtime, MCP server, plugin or hooks. It says the integration is absent, points to `$agentcairn-setup` or the native install steps, and halts the memory workflow until the host restarts.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add ccf/agentcairn --skill using-agentcairn-memory -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/using-agentcairn-memory/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/using-agentcairn-memory/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add ccf/agentcairn --skill using-agentcairn-memory -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/using-agentcairn-memory/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add ccf/agentcairn --skill using-agentcairn-memory -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/using-agentcairn-memory/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install ccf/agentcairn using-agentcairn-memory
```

2. **Manually: put the files in place**
- File: `.github/skills/using-agentcairn-memory/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add ccf/agentcairn --skill using-agentcairn-memory -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/ccf/agentcairn --path plugin/skills/using-agentcairn-memory
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/using-agentcairn-memory/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add ccf/agentcairn --skill using-agentcairn-memory -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/ccf/agentcairn/tree/HEAD/plugin/skills/using-agentcairn-memory/SKILL.md

## When to use it
- find how the auth token refresh was fixed last time
- recover the migration order already agreed on
- pin a non-obvious fix so it is not re-derived
- keep a stated user preference about merge style
- pull a solution from another repo facing a similar task

## Example prompts
- Search memory for how we fixed the auth token refresh
- Remember this: we rotate jwt-secret on deploy via X
- Limit the memory query to this project and find the note about migration order

# Using agentcairn memory

You have a persistent memory backed by agentcairn (a Markdown vault the user owns). Use it.

## Require the full integration

This skill assumes AgentCairn's MCP tools are already loaded. Before following
the memory workflow, confirm that `recall` and `remember` are available.

If the tools are missing:

- Do not invent tool calls or imply that this behavior skill installed the
  AgentCairn runtime, MCP server, plugin, or hooks.
- Explain that the full AgentCairn integration is not loaded.
- Invoke `$agentcairn-setup` if available, or direct the user to the native
  AgentCairn installation instructions.
- Stop the memory workflow until installation is complete and the host has been
  restarted.

## Recall before you work
Before designing, debugging, or re-deriving something non-trivial, **search memory first**:
- Use the `recall` tool (hybrid search) with a focused query — "how did we fix the auth token refresh?", "what did we decide about the migration order?".
- Expand a promising hit with `build_context` to read the full note.
- Recall is cross-project: prior solutions in *any* repo can help. Cite notes by permalink.
- Recall automatically prefers your current project's memories while still surfacing relevant cross-project ones (marked `[from: <project>]`); pass a project to target another repo, or `--scope project` to limit a query to just this one.

## Remember durable facts
After a decision, a non-obvious fix, a gotcha, or a stated user preference, **persist it** with the
`remember` tool — a short, self-contained fact. Good memories: "We rotate jwt-secret on deploy via
X.", "User prefers rebase-merges.", "DuckDB TIMESTAMP stores naive-UTC — bind accordingly."
Skip the trivial — the SessionEnd hook already captures the session in bulk; `remember` is for the
high-value things worth pinning deliberately.

The vault is plain Markdown the user can read and edit; treat it as shared, durable knowledge.
