What it does
Markdown Rendering is an agent skill from sickn33/agentic-awesome-skills. Open Markdown reliably in cmux panes and recover from blank rendered surfaces.
Its SKILL.md is about 750 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 Documents & Office, covering Markdown. The repository describes itself as: AAS Core is the local, agent-first control plane for complete catalog discovery, agent-owned selection, stack validation, and planning, backed by 2,400+ agentic skills. Includes… The licence is MIT.
When your agent uses it
- Tasks that involve Markdown
Example prompts
- “/markdown-rendering”
What it can do on your machine
Read from SKILL.md and the folder at commit 1e53ce2. 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 (its code samples are bash).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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
Markdown Rendering loads about 751 tokens when it runs. Until then it costs about 24 tokens; SKILL.md has 328 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.

Markdown Rendering in cmux
When to Use
- Use when opening Markdown in cmux shows a blank pane or wrong layout.
- Use when you need to display a Markdown file in a stable cmux right pane.
The Problem
cmux markdown open defaults to spawning a brand-new pane every time, even with --direction right. The common "fix" — moving the new markdown surface into the existing right pane with move-surface — bugs out: the moved viewer renders BLANK. The surface keeps type=markdown and looks healthy, but shows nothing.
So you get stuck: either a stray extra pane, or a blank viewer after moving it.
The Rule
You have exactly two reliable options. Never move-surface a markdown viewer — that is the path that bugs.
Option A — Open it right on the first try
If there is no usable right pane yet, just let cmux create one and leave it where it lands:
cmux markdown open /abs/path/file.md --direction right --focus falseDo NOT then move it. If it spawned where you want it, you're done.
Option B — Close existing right pane(s), then open fresh
If there are other right panes in the way (and they're unused or irrelevant), close them first, then open the markdown fresh as a new right pane:
# 1. find panes in THIS workspace
cmux list-panes --workspace "$CMUX_WORKSPACE_ID"
# 2. close the unused/irrelevant right pane(s) by closing their surfaces
cmux list-pane-surfaces --pane pane:NN
cmux close-surface --surface surface:XX # repeat per surface in that pane
# 3. THEN open the markdown fresh — it creates its own clean right pane
cmux markdown open /abs/path/file.md --direction right --focus falseHard Rules
- Never
move-surfacea markdown viewer. It renders blank afterward. This is the core bug this skill exists for. - Open it correctly the first time (Option A), OR close the conflicting right pane(s) and open a fresh right pane from scratch (Option B).
- Only close panes that are unused or irrelevant — never close a pane the user is working in.
- Always anchor to
$CMUX_WORKSPACE_ID; never assume the visually focused workspace. - Pass
--focus falseso you don't steal the user's focus. - You can't screenshot/read a markdown surface to verify it. If unsure it rendered, ask the user.
Limitations
- Adapted from
davidondrej/skills; verify local paths, tools, credentials, and agent features before acting. - For commands, remote access, scheduling, browser automation, or file-changing workflows, get explicit user approval and confirm the target environment first.
