Claude Code Skills Marketplace is a collection and marketplace of skills, plugins, agents, and instructions that extend Claude Code with specialized development workflows. It is for developers who want to install existing workflows or create, validate, and package their own Claude Code skills.
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: 3 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 →

Skills should not maintain state across sessions without explicit user consent.
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 | $0.00118 | $0.03261 |
| Opus 5.5 | $0.00047 | $0.01304 |
| Sonnet 5.5 | $0.00024 | $0.00652 |
| Haiku 4.5 | $0.00012 | $0.00326 |
Grade A, and why
ima-copilot 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 17d 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 — 195 lines — stays where its author put it; the contents beside it link to each section on GitHub.
IMA Copilot
One-command installer, troubleshooter, and personalization layer for the official Tencent IMA skill.
Overview
The official Tencent IMA skill (ima-skill) exposes a powerful OpenAPI for notes and knowledge base operations, but its installation flow is designed for a specific proprietary agent and recent releases have shipped submodule files that fail strict SKILL.md loaders. IMA Copilot solves both problems:
- Installs ima-skill to Claude Code, Codex, and OpenClaw in a single command via the vercel-labs/skills open installer.
- Walks the user through API key setup with a live validation call.
- Detects known upstream issues and — with explicit user consent — fixes them in place, without ever forking, vendoring, or mirroring any part of the upstream package.
- Provides a fan-out search strategy that respects user-configured knowledge base priorities and boosts, with awareness of the 100-result per-KB truncation limit.
Architectural principles (do not violate)
This skill is a wrapper layer around ima-skill. The wrapper contract is non-negotiable:
- Never vendor upstream files. This skill directory does not contain any copy, fork, or excerpt of ima-skill's own content. When ima-skill ships a new release, users get the new release without any interference from this wrapper.
- Repairs happen at runtime, not at ship time. If an upstream bug needs patching, this skill carries the instructions for how to patch, not the patched files. Running a repair is idempotent: rerunning after an upstream update re-detects and re-fixes anything that came back.
- Always ask before touching upstream files. Modifying
~/.claude/skills/ima-skill/**,~/.agents/skills/ima-skill/**, or any other upstream install directory requires explicit user consent via AskUserQuestion. No silent patching. - Teach rather than hide. When a fix is applied, show the user exactly what changed and where the backup was saved. This is how users learn to maintain their own installs.
What ships with it
9 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.

ima-copilot is a skill published in the GitHub repository daymade/claude-code-skills (1,473 stars, last pushed today), licensed MIT. It adds 118 tokens to every session and 3,261 once invoked, about $0.0005 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 2026-09-03.
