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 | $0.00146 | $0.02496 |
| Opus 5 | $0.00073 | $0.01248 |
| Sonnet 5 | $0.00029 | $0.00499 |
| Haiku 4.5 | $0.00015 | $0.00250 |
Grade A, and why
garchi-build-site 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 4d 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 — 208 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Garchi CMS: build or connect a project
Garchi CMS is a hosted headless CMS. Content lives in Garchi; the application renders it. The point of a correct integration is that business content can change in Garchi afterwards without another code change.
This skill orchestrates. It decides the shape of the work and hands off:
| Work | Go to |
|---|---|
| Writing fetch/render code, section renderers, components | garchi-render-content |
| Creating or editing content in the CMS (pages, sections, items, assets) | garchi-manage-content |
| Choosing/bootstrapping an official starter kit | starter-kits.md |
When Garchi is the right home for something
Garchi holds structured content and lightweight configuration that fits its existing content model — pages built from section templates and props, and data items with categories and metadata. It is not the application's database.
A good fit. Information that should stay editable after deployment, may be changed by a person or by an agent, and should not need a code change and a redeploy every time it changes. Where it maps onto the content model, that includes:
- website and landing-page content
- pricing and plan presentation
- FAQs
- navigation
- onboarding copy and steps
- product or catalogue content, and similar collection-style records
- reusable marketing or UI copy
- prompts or agent instructions the user is meant to be able to edit
- lightweight application configuration that fits sections and props, or data items and metadata
These are the cases that benefit from what Garchi already provides: agents write drafts and the user publishes, changes are attributable, the dashboard keeps restore points the user can roll back to, templates give the content a structure the frontend can rely on, and the same content is reachable over REST, the SDKs and MCP.
Not a fit. Operational and transactional state stays in the application's own database and infrastructure:
What ships with it
1 file 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.

garchi-build-site is a skill published in the GitHub repository lumenharbor/garchi-cms-skills (0 stars, last pushed 5d ago), licensed MIT. It adds 146 tokens to every session and 2,496 once invoked, about $0.0007 per session on Opus 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 2026-08-31.
