# centminmod / claude-plugins
- Site:
- Article:
A personal Claude Code plugin marketplace. Each plugin is an independent, standalone unit that can be installed into any Claude Code project with a single command.
> Claude Code's plugin system supports multiple plugins per marketplace and handles install + update lifecycle automatically. See the [official plugin-marketplaces docs](https://code.claude.com/docs/en/plugin-marketplaces) for the broader ecosystem.
## Install the marketplace
Add this marketplace once, then install any plugin from it:
> **Run `/plugin` commands inside the Claude Code terminal CLI**
> (`claude` in your shell). They are not recognised in the desktop
> app, claude.ai/code, or IDE extensions — you'll see *"/plugin isn't
> a recognized command here"* if you try. Installed plugins then work
> from every surface; only the install step requires the CLI.
```
/plugin marketplace add centminmod/claude-plugins
```
## Available plugins
| Plugin | Description | Install |
|--------|-------------|---------|
| [`session-metrics`](plugins/session-metrics) | Per-turn token, cost, and cache metrics for Claude Code sessions. Multi-format export (text/JSON/CSV/MD/HTML) with 5-hour session blocks, weekly roll-up, hour-of-day punchcard, and pluggable chart libraries. | `/plugin install session-metrics@centminmod` |
More plugins coming.
### Further reading — `session-metrics`
Background articles by the author on what the skill does and what it
surfaces in practice:
- [My Claude Code Plugin Marketplace Is Now Public. Install Session Metrics Skill Plugin](https://ai.georgeliu.com/p/my-claude-code-plugin-marketplace).
- [I built a token-cost analyzer skill for Claude Code](https://ai.georgeliu.com/p/i-built-a-token-cost-analyzer-skill) — how the skill was designed and what it reports.
- [I ran two Claude Opus 4.7 5-hour sessions](https://ai.georgeliu.com/p/i-ran-two-claude-opus-47-5hr-sessions) — real-world session-metrics output from two back-to-back Opus 4.7 sessions, with cache-hit, cost, and token-usage analysis.
## How the skill gets triggered
Plugin skills are namespaced as `plugin-name:skill-name` — for example
`/session-metrics:session-metrics`. In practice you rarely type that form:
each skill declares natural-language triggers in its `SKILL.md`, so Claude
Code auto-invokes the right one when you ask something like *"how much has
this session cost?"*.
## Licences
- Marketplace scaffold: MIT (see [`LICENSE`](LICENSE)).
- Each plugin under `plugins/*/` carries its own `LICENSE` and may bundle
third-party assets under their upstream licences. For `session-metrics`
specifically, the default Highcharts renderer ships under a
non-commercial-free licence — commercial use requires a paid Highsoft
licence. MIT-licensed alternatives (uPlot, Chart.js) are selectable via
the `--chart-lib` flag. See
[`plugins/session-metrics/skills/session-metrics/scripts/vendor/charts/README.md`](plugins/session-metrics/skills/session-metrics/scripts/vendor/charts/README.md)
for per-library LICENSE.txt files.
## Contributing
This is a personal marketplace — issues and pull requests are welcome but
plugin additions are curated. Feel free to open an issue to discuss
bundling something new.
