MARVIN is a personal AI assistant built to remember conversations, track goals, organize work, and connect to external applications. People use it as a chief-of-staff-style extension for Claude Code or GitHub Copilot CLI, with integrations including Google Workspace, Microsoft 365, Slack, Linear, Notion, and Telegram. The catalogue entries provide commands, agents, skills, and instructions that define MARVIN's workflows.

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 | $0.00013 | $0.00471 |
| Opus 5 | $0.00006 | $0.00235 |
| Sonnet 5 | $0.00003 | $0.00094 |
| Haiku 4.5 | $0.00001 | $0.00047 |
Grade A, and why
skills 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 9d 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.
What it actually says
/skills - Skill Discovery
Manage and discover agent skills from the open skills ecosystem.
Argument: $ARGUMENTS (expects a sub-command: list, search <query>, install <package>, update)
Sub-Commands
No argument / help
Show available sub-commands:
/skills list Show installed skills
/skills search <query> Search the skills.sh ecosystem
/skills install <pkg> Install a skill (with confirmation)
/skills update Check for and apply skill updates
list
Show currently installed skills.
npx skills list 2>/dev/null || echo "Skills CLI not found. Install with: npm i -g skills"
Present results grouped by scope (global vs project-level).
search <query>
Search the skills.sh ecosystem for skills matching the query.
npx skills find <query>
- Parse results into a clean list: skill name, description, install command
- Present numbered options
- Ask: "Want me to install any of these?"
- If yes, run the install flow below
install <package>
Install a skill with confirmation.
- Show the skill name and package identifier
- Link to the skills.sh page if available:
https://skills.sh/<owner>/<repo>/<skill> - Ask: "Install this skill? (y/n)"
- On confirmation:
npx skills add <package> -g -y - Confirm success or report errors
update
Check for and apply skill updates.
npx skills check
If updates are available:
- List skills with available updates
- Ask: "Update all, or pick specific ones?"
- Run:
npx skills update
Notes
- Browse skills visually at https://skills.sh
- Skills install to
~/.agents/skills/(global) or.agents/skills/(project) - The
find-skillsskill enables proactive skill suggestions during normal conversation
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.
