Agent Skills: Gitea Wiki Manager

Gitea Wiki Manager

Overview

Manage Gitea wiki pages using MCP tools. Wiki content is base64 encoded - use shell commands to decode/encode, avoiding large base64 strings in LLM context.

Workflows

Reading a Wiki Page

Step 1: Call MCP tool
        mcp__gitea__get_wiki_page(owner="user", repo="myrepo", pageName="Home")

Step 2: Response contains content_base64 field
        Extract the base64 string from response

Step 3: Decode using Bash (NOT in LLM context)
        echo "<content_base64_value>" | base64 -d > /tmp/wiki-page.md

Step 4: Read decoded file
        Use Read tool on /tmp/wiki-page.md

Creating a Wiki Page

Step 1: Write content to temp file
        Use Write tool to create /tmp/new-page.md with content

Step 2: Encode to base64 using Bash
        base64 < /tmp/new-page.md | tr -d '\n'

Step 3: Call MCP tool with base64 output
        mcp__gitea__create_wiki_page(
          owner="user",
          repo="myrepo",
          title="API Docs",
          content_base64="<output_from_step_2>"
        )

Updating a Wiki Page

Step 1: Get current content
        mcp__gitea__get_wiki_page(owner="user", repo="myrepo", pageName="Home")

Step 2: Decode to temp file
        echo "<content_base64>" | base64 -d > /tmp/edit-page.md

Step 3: Edit the temp file
        Use Edit tool on /tmp/edit-page.md

Step 4: Re-encode
        base64 < /tmp/edit-page.md | tr -d '\n'

Step 5: Call MCP update
        mcp__gitea__update_wiki_page(
          owner="user",
          repo="myrepo",
          pageName="Home",
          content_base64="<output_from_step_4>"
        )

Guidelines

Do

• Use temp files (/tmp/wiki-*.md) for content manipulation
• Use tr -d '\n' when encoding - API requires no line breaks
• Clean up temp files after operations
• Decode content via Bash before reading

Don't

• Include raw base64 content in LLM responses
• Skip the decode step when reading wiki pages
• Forget to encode content before creating/updating pages
• Leave temp files after operations complete

Examples

Example: Read Home page

1. mcp__gitea__get_wiki_page(owner="acme", repo="docs", pageName="Home")
   → Response: {"content_base64": "IyBXZWxjb21l..."}

2. Bash: echo "IyBXZWxjb21l..." | base64 -d > /tmp/wiki-home.md

3. Read: /tmp/wiki-home.md
   → Shows: "# Welcome..."

Example: Create new page

1. Write /tmp/new-wiki.md:
   # Installation
   Run `npm install`

2. Bash: base64 < /tmp/new-wiki.md | tr -d '\n'
   → Output: IyBJbnN0YWxsYXRpb24KUnVuIGBucG0gaW5zdGFsbGA=

3. mcp__gitea__create_wiki_page(
     owner="acme",
     repo="docs",
     title="Installation",
     content_base64="IyBJbnN0YWxsYXRpb24KUnVuIGBucG0gaW5zdGFsbGA="
   )
