About this skill

Context Mode Doctor is a skill in mksglu/context-mode (26k stars). Its SKILL.md is about 262 tokens. Licence: Custom licence.

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Call the ctx_doctor MCP tool directly. It runs all checks server-side and returns a plain-text status report.
  2. Display the results verbatim — they are already formatted with plain-text status prefixes: [OK] PASS, [FAIL] FAIL, [WARN] WARN…
  3. Fallback (only if MCP tool call fails): Derive the plugin root from this skill's base directory (go up 2 levels — remove…

What it can do on your machine

Read from SKILL.md and the folder at commit f33a26e. 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

    Shell commands in SKILL.md call:

    • node

    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

Context Mode Doctor loads about 262 tokens when it runs. Until then it costs about 39 tokens; SKILL.md has 96 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~39
When it runs · the whole SKILL.md, loaded when a task matches
~262

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

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 96 words (~262 tokens).

“Run diagnostics and display results directly in the conversation.”

Can I use Context Mode Doctor in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add mksglu/context-mode --skill ctx-doctor -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/ctx-doctor, .gemini/skills/ctx-doctor, .github/skills/ctx-doctor and .opencode/skills/ctx-doctor in your project.
