Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 10 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00091 | $0.01593 |
| Opus 5.5 | $0.00036 | $0.00637 |
| Sonnet 5.5 | $0.00018 | $0.00319 |
| Haiku 4.5 | $0.00009 | $0.00159 |
Grade A, and why
agentcairn-setup scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 173 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AgentCairn setup
Set up the full AgentCairn integration by delegating to AgentCairn's native, preview-first installer. Treat this skill as a management layer only: installing this skill does not install the AgentCairn runtime, MCP server, plugin, or hooks.
Preserve the boundary
- Use
uvx --from agentcairn cairn installas the source of truth for supported hosts and generated configuration. - Do not copy plugin files, write MCP configuration by hand, or reproduce the installer's host-specific logic.
- Do not claim AgentCairn is ready merely because this setup skill is present.
- Do not use plain
uvx cairn; that resolves an unrelated package. Useuvx --from agentcairn cairn .... - Use
--vaultonly for MCP hosts. Configure plugin-host vaults through the plugin or AgentCairn's shared configuration. - Do not install or repair every detected host unless the user explicitly asks.
- Do not write a test memory without the user's approval.
1. Establish the target
Check whether AgentCairn's recall and remember MCP tools are already loaded.
If they are available and the user did not request an upgrade or repair, report
that the full integration is active and move to verification.
Identify the current or requested host. Use these installer IDs:
| Host | Installer ID | Integration |
|---|---|---|
| Claude Code | claude-code |
Native plugin, MCP tools, skill, and hooks |
| Codex | codex |
Native plugin, MCP tools, skill, and hooks |
| Cursor | cursor |
MCP configuration and memory skill |
| OpenCode | opencode |
MCP configuration, commands, and native plugin |
| Antigravity | antigravity |
Native plugin; requires a local plugin source |
| VS Code / Copilot | vscode |
MCP configuration |
| Claude Desktop | claude-desktop |
MCP configuration |
| Gemini CLI | gemini |
MCP configuration |
Treat Hermes Agent separately because it uses a native MemoryProvider, not
cairn install:
hermes plugins install ccf/agentcairn/integrations/hermes
hermes memory setup agentcairn
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- 1mo ago First seen · 173 lines · 91 tokens per session scan A 52339707261a
agentcairn-setup is a skill published in the GitHub repository ccf/agentcairn (67 stars, last pushed 5d ago), licensed Apache-2.0. It adds 91 tokens to every session and 1,593 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other skills, from other repositories
agentmemory-config
Set up and diagnose local agentmemory, including MCP, environment variables, ports, and feature flags. Use when getting started, checking a connection, enabling a feature, configuring auth, or explaining why a feature is off by default.
agentmemory-agents
How agentmemory wires into host coding agents via the connect command. Use when installing agentmemory into a specific agent, when asked which agents are supported, or when a connect adapter writes the wrong config path.
memory-discipline
The session loop that makes agentmemory pay off, recall before starting work, save at decision points, learn from corrections. Use when starting a nontrivial task, after settling a decision or debugging a gotcha, or whenever deciding if something belongs in memory.
agentmemory-hooks
The agentmemory plugin hooks that capture observations automatically across the agent session lifecycle. Use when explaining how memory gets captured without manual saves, when debugging missing observations, or when tuning what gets recorded.
forget
Delete selected durable memories from agentmemory after showing them and getting explicit confirmation. Use when the user says "forget this", "delete memory", "remove that note", or wants to scrub specific data for privacy.
handoff
Resume the most recent agent session for the current working directory, leading with any unanswered question. Use when the user says "where were we", "resume", "handoff", "pick up where I left off", or starts a session with no fresh context.
