What it does

External Context is an agent skill from jmstar85/oh-my-githubcopilot. Gather external documentation context through focused, bounded research passes. Activate when: external context, docs research, external docs, look up docs.

Its SKILL.md is about 250 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

Example prompts

  • “/external-context”

Workflow steps

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

  1. Clarify the exact technology, API, version, and decision to support.
  2. Search local repository docs first.
  3. Fetch official or primary external documentation when URLs are provided or needed.
  4. Summarize only the details relevant to the current implementation decision.
  5. Cite source URLs and note version/date sensitivity.

What it can do on your machine

Read from SKILL.md and the folder at commit 12b2c29. 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

    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

External Context loads about 249 tokens when it runs. Until then it costs about 43 tokens; SKILL.md has 104 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~43
When it runs · the whole SKILL.md, loaded when a task matches
~249

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.

<technology or question>

External Context

OMG adapted scope: This port uses sequential or small batched research passes. It does not guarantee OMC-style parallel document-specialist execution.

Workflow

  1. Clarify the exact technology, API, version, and decision to support.
  2. Search local repository docs first.
  3. Fetch official or primary external documentation when URLs are provided or needed.
  4. Summarize only the details relevant to the current implementation decision.
  5. Cite source URLs and note version/date sensitivity.

Rules

  • Use official docs before blog posts when possible.
  • Do not overfetch unrelated links.
  • Separate source facts from recommendations.
  • If the user provides URLs, fetch and inspect them before relying on memory.
