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.

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 | $0.00078 | $0.01319 |
| Opus 5.5 | $0.00031 | $0.00528 |
| Sonnet 5.5 | $0.00016 | $0.00264 |
| Haiku 4.5 | $0.00008 | $0.00132 |
Grade D, and why
claude-skills-troubleshooting scanned grade D with 2 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.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

Claude Skills Troubleshooting
Overview
Diagnose and resolve common Claude Code plugin and skill configuration issues. This skill provides systematic debugging workflows for plugin installation, enablement, and activation problems.
Quick Diagnosis
Run the diagnostic script to identify common issues:
python3 scripts/diagnose_plugins.py
The script checks:
- Installed vs enabled plugins mismatch in both directions (installed-but-not-enabled and enabled-but-not-registered)
- Missing enabledPlugins entries in settings.json
- Stale marketplace cache using
known_marketplaces.jsonlastUpdated - Missing, malformed, timezone-free, or future
lastUpdatedmetadata - Invalid plugin configurations
Treat lastUpdated as the only cache-freshness source. Do not fall back to
cache-directory modification times: marketplace updates can refresh nested
files without changing that directory timestamp. The diagnostic exits nonzero
for stale caches or invalid freshness metadata.
Common Issues
Issue 1: Plugin Installed But Not Showing in Available Skills
Symptoms:
/pluginshows plugin as installed- Skill not appearing in Skill tool's available list
- Plugin metadata exists in
installed_plugins.json
Root Cause: Known bug (GitHub #17832) - plugins are added to installed_plugins.json but NOT automatically added to enabledPlugins in settings.json.
Diagnosis:
# Check if plugin is in installed_plugins.json
cat ~/.claude/plugins/installed_plugins.json | grep "plugin-name"
# Check if plugin is enabled in settings.json
cat ~/.claude/settings.json | grep "plugin-name"
Solution:
# Option 1: Use CLI to enable
claude plugin enable plugin-name@marketplace-name
# Option 2: Manually edit settings.json
# Add to enabledPlugins section:
# "plugin-name@marketplace-name": true
Mirror variant — enabled but not registered: If diagnosis instead shows the plugin in enabledPlugins but NOT in installed_plugins.json, the cause is the symlink-skip bug: the install ran under a config dir where installed_plugins.json is a symlink (multi-profile shared setups), and the CLI silently skipped writing it. See references/known_issues.md → "Symlinked installed_plugins.json". Fix:
What ships with it
4 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.

claude-skills-troubleshooting is a skill published in the GitHub repository daymade/claude-code-skills (1,516 stars, last pushed yesterday), licensed MIT. It adds 78 tokens to every session and 1,319 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it D with 2 findings (reads agent configuration directories, recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
