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.

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 | $0.00000 | $0.00331 |
| Opus 5.5 | $0.00000 | $0.00132 |
| Sonnet 5.5 | $0.00000 | $0.00066 |
| Haiku 4.5 | $0.00000 | $0.00033 |
Grade B, and why
docs scanned grade B with 1 finding 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
The same `vs skill install` call also writes an `mcpServers.vibesurfer = {command: "vs", args: ["mcp"]}` entry into each agent's MCP config (`.claude.json`, `~/.codex/config.toml`, `<workspace>/.cursor/mcp.json`, `~/.gem What it actually says
Skill
The skill that gets installed into every detected agent by vs skill install lives at:
That file is the single source of truth — it's what the agent reads, and it's the file vs skill install writes (verbatim) into each agent's conventional skill location:
| Agent | Path |
|---|---|
| Claude Code | ~/.claude/skills/vibesurfer/SKILL.md |
| Codex CLI | ~/.codex/skills/vibesurfer/SKILL.md |
| Cursor | <workspace>/.cursor/skills/vibesurfer/SKILL.md |
| Gemini | ~/.gemini/extensions/vibesurfer/GEMINI.md (renamed) |
| OpenClaw | ~/.openclaw/workspace/skills/vibesurfer/SKILL.md |
| Canonical | ~/.agents/skills/vibesurfer/SKILL.md |
The same vs skill install call also writes an mcpServers.vibesurfer = {command: "vs", args: ["mcp"]} entry into each agent's MCP config (.claude.json, ~/.codex/config.toml, <workspace>/.cursor/mcp.json, ~/.gemini/settings.json, Library/Application Support/Claude/claude_desktop_config.json on macOS) so the agent can talk to vibesurfer over MCP as well as via the SKILL.md.
What ships with it
23 files 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.

docs is a skill published in the GitHub repository frane/vibesurfer (16 stars, last pushed 25d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 331 tokens. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

checking-a-page
Check that a web page you wrote or changed actually works, by opening it in a browser and driving every control on it. Use after creating or editing an HTML page, or the JavaScript or CSS that a page loads.
kane-cli
End-to-end (E2E) test generation and execution with KaneCLI. Generate tests from a PRD, specification, or user-provided description via the assurance commands (use-cases, acceptance criteria, scenarios, runnable test.md tests; never write test cases by hand). Execute them on desktop web (Chrome, the default), Android…
opencli-usage
Discover and invoke OpenCLI capabilities for websites and Chrome. Find commands, inspect schemas, interpret results and choose browser or adapter tools.
ouroboros-run
Use when an Ouroboros Seed (a spec file with a goal and acceptance criteria, such as .seed.yaml) already exists and the user wants it executed: 'run the seed', 'execute this spec', 'ooo run'. Executes it and verifies every acceptance criterion. Not for raw requests without a Seed (use interview or auto).
evolve
Start or monitor an evolutionary development loop.
ouroboros-status
Check session status and measure goal drift.
