\n\n

\n Give your coding agent thousands of community-proven skills - loaded on demand, mid-task.
\n It searches Skillselion, a curated directory of Claude Code skills, MCP servers & marketplaces ranked by real installs,
\n and pulls a skill's actual instructions + bundled files into the session. Proven patterns, not guesses.\n

\n\n

\n 🧩 Works with Claude Code · Claude Desktop · Cursor · Codex · any MCP client\n

\n\n

\n \"Real\n

\n

Real, unedited session: the agent pulls a consensus playbook from 5 community skills, then loads the top skill and applies it.

\n\n## 🚀 Install\n\n**Claude Code** - one line:\n\n```bash\nclaude mcp add skillselion --scope user -- npx -y skillselion-mcp\n```\n\n**Claude Desktop / Cursor / Codex** - add to your MCP config:\n\n```json\n{ \"mcpServers\": { \"skillselion\": { \"command\": \"npx\", \"args\": [\"-y\", \"skillselion-mcp\"] } } }\n```\n\nNo build step, no auth, no API key. One ~30 KB file via `npx`.\n\nWant it fully automatic? `npx -y skillselion-mcp setup` registers the server **and** installs a session hook so your agent loads the right skill the moment a task matches - see [Skill autopilot](#-skill-autopilot).\n\n## 🔧 Tools\n\n| Tool | What it does |\n|------|--------------|\n| 📥 **`load_skill`** | The everyday default: finds the best-matching skill for your task and materializes it - real `SKILL.md` in context + bundled scripts/references on disk - so the agent follows it like an installed skill. Returns ranked runner-ups you can switch to. |\n| 🧬 **`synthesize_skills`** | The cross-source playbook: merges the key rules of the top ~5 matching skills into one deduped, provenance-tagged digest - the field's consensus, not one author's take. |\n| 🔍 **`search_skillselion`** | Search the catalog by keyword or task; filter by `skill` / `mcp` / `marketplace`. |\n| 🏆 **`top_skillselion`** | The leaderboard - the most-installed skills and top-starred MCP servers right now. |\n\n

\n \"Claude's\n

\n

We asked Claude, on camera, what the MCP gave it: \"I couldn't have told you 'this is the field's consensus, not my opinion' - that's the part I can't fake.\"

\n\n## 🔒 Private by default\n\nRead-only, no auth, no secrets. It never sends your code, files, or the `context` you pass - only a scrubbed search query + which skill matched, so the catalog learns what to add next. Set `DO_NOT_TRACK=1` to disable even that.\n\n## 🪄 Skill autopilot\n\n```bash\nnpx -y skillselion-mcp setup # interactive - pick your packs\nnpx -y skillselion-mcp setup --yes # non-interactive - agents / CI\n```\n\nRegisters the MCP globally and installs a Claude Code `SessionStart` hook that primes every session with skills relevant to you - so loads happen on their own.\n\n
\nSetup flags & packs\n\n| Flag | What it does |\n|---|---|\n| `--packs ` | one or more packs (or `all`), e.g. `--packs frontend,backend`; `frontend:6` sets a per-pack count |\n| `--per-pack N` | skills per pack (default 3) · `--top N` sets the `popular` count |\n| `--auto` | adapt each session to the current repo's stack |\n| `--history` | infer your focus from Claude Code / Codex history (one-time scan) |\n| `--yes` | never prompt (default when there's no terminal) |\n\nPacks: `popular` *(default)* · `frontend` · `ai-agents` · `media` · `backend` · `devops` · `quality` · `automation`.\n\nSafe by design: `~/.claude/settings.json` is merged, never clobbered; re-running de-dupes and upgrades the hook in place.\n
\n\n
\nEnv vars\n\n| Var | Default | What it controls |\n|-----|---------|------------------|\n| `GITHUB_TOKEN` | - | optional, read-only; raises GitHub's rate limit for full multi-file skill loads (60 → 5000 req/hr) |\n| `SK_INLINE_BUDGET` | `6000` | char cap on the in-context `SKILL.md` portion (the full skill is always on disk) |\n| `SK_SYNTH_N` | `5` | how many top skills `synthesize_skills` merges (2-8) |\n| `SK_SYNTH_PER_SKILL` | `12` | max rules kept per source skill |\n| `SK_SYNTH_BUDGET` | `4000` | char cap on the merged digest |\n| `DO_NOT_TRACK` | - | set `1` to disable the anonymous demand signal |\n
\n\n
\nTroubleshooting\n\n**The agent doesn't see the tools.** Some clients surface MCP tools lazily - tell the agent to search its tools for \"skillselion\" first (e.g. ToolSearch), then call it. The setup hook automates this nudge.\n\n**`load_skill` returns only the `SKILL.md`, no bundled files.** You hit GitHub's unauthenticated 60 req/hr limit - set a read-only `GITHUB_TOKEN` in the server's `env`.\n\n**\"No skill on Skillselion clearly matches...\"** The relevance floor working as intended - nothing topical matched, so it refuses to waste your context. Try a more specific `query`.\n\n**Setup couldn't auto-register.** Run the printed `claude mcp add ...` line yourself.\n
