What is garchi-manage-content?

Instructions for managing website and application content in Garchi, a hosted content management system where content is stored separately from the code that displays it. It covers pages, sections, templates, data items, categories, assets, and languages through Garchi's MCP server.

Use it to create or edit pages, page sections, blog posts, products, images, categories, and other structured content in Garchi.

It prevents content changes from being handled as source-code edits when they belong in the CMS. It also requires looking up valid content IDs and current CMS rules before making changes.

garchi-manage-content — Skill for Claude Code by lumenharbor

Install

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.

Any agent

npx skills add lumenharbor/garchi-cms-skills --skill garchi-manage-content

Clone the repo

git clone --depth 1 https://github.com/lumenharbor/garchi-cms-skills

Made for: Claude Code.

Or install garchi-cms, the plugin that ships this one along with the rest of its 3 skills, 1 MCP server.

Token cost

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	$0.00113	$0.03249
Opus 5	$0.00056	$0.01625
Sonnet 5	$0.00023	$0.00650
Haiku 4.5	$0.00011	$0.00325

Measured 4d ago against content hash 7963255cc7f0, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-12, from the pricing page.

Security

Grade A, and why

garchi-manage-content 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 — 259 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Garchi CMS: operating content over MCP

Content lives in the CMS. If the user wants different copy, a new page, a new blog post or a different image, that is an MCP operation and the application code should not change at all.

Requires the garchi MCP server. If its tools are unavailable, stop and ask the user to authorize it. Do not substitute source edits for CMS edits.

Start every session by calling get-garchi-cms-guide. It is free, read-only, takes no arguments, and returns the current content model and field rules straight from the server. It is more current than this file. Read it before planning any write.

The one thing to understand: ids flow between calls

Almost every Garchi tool takes an id that a previous call returned. Nothing is derivable, nothing is guessable. Most failed Garchi sessions are an agent inventing an id instead of listing for it.

        upsert-section-content-tool
        (needs page_id + section_id + prop template ids)

Two id traps worth knowing:

get-page-tool takes a slug (/, /about), not a page id. But upsert-section-content-tool, delete-section-tool and the rank tools take a page_id. Get the id from list-pages-tool and the section ids from get-page-tool.
get-data-item-tool, update-data-item-tool and create-meta-for-item-tool take a numeric item_id, not the slug.

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.
