What it does
Edithdoc is an agent skill from Th4nat0s/Chall_Tools. Use this skill when the task involves creating, reading, editing, updating, fixing, or undoing notes on the CSIRT HedgeDoc/HDOC instance through the edithdoc MCP server, including any hdoc. or HedgeDoc URL where the note may matter.
Its SKILL.md is about 610 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows, covering MCP servers. It works with Model Context Protocol. The repository describes itself as: Tools for security challenges.
When your agent uses it
- The task involves creating
- Undoing notes on the CSIRT HedgeDoc/HDOC instance through the edithdoc MCP server
- Including any hdoc
Example prompts
- “/edithdoc”
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Identify whether the user wants to create, read, edit, or undo an HDOC note.
- Prefer read_note before any destructive or broad edit.
- Preserve existing content unless the user explicitly asks to replace it.
- When editing, produce the final Markdown content first, then call write_note.
- After write_note, summarize what changed.
- If the user says the change was wrong, use undo_note.
What it can do on your machine
Read from SKILL.md and the folder at commit 259e5ce. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
demo.hedgedoc.org
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Edithdoc loads about 605 tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 316 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 316 words (~605 tokens).
“Use the edithdoc MCP server whenever the user asks to create, read, modify, rewrite, append to, correct, or undo changes in an HDOC/HedgeDoc note.”
