gist-management

gist-management is a skill for Claude Code, Codex from ofershap/mcp-server-github-gist. It costs 34 tokens per session (394 once invoked), scanned A, original, MIT.

A GitHub Gist manager for saving and handling small code files or snippets. It can create, read, update, delete, list, and star gists through GitHub.

In plain words
What is it for?
Use it to save snippets as public or secret gists, read their file contents, update files or descriptions, browse your gists, and manage stars. It requires a GitHub token with Gist access.
Why use it?
It lets an agent manage shared code snippets without switching to GitHub manually. It also covers Gists, which are not handled by the standard GitHub MCP server described here.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

gist-management scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

GitHub Gist Management via MCP

Use this skill when you need to create, read, update, or manage GitHub Gists. Fills the gap the official GitHub MCP server leaves for Gists.

Available Tools

Tool What it does
gist_list List your gists (paginated)
gist_get Get a gist by ID (includes file contents)
gist_create Create a new gist (public or secret)
gist_update Update description or file contents
gist_delete Delete a gist
gist_starred List your starred gists
gist_star Star a gist
gist_unstar Unstar a gist

Workflow

  1. gist_create to save code snippets — specify public: false for secret gists (default)
  2. gist_list to browse existing gists
  3. gist_get with a gist ID to read file contents
  4. gist_update to modify description or files

Key Patterns

  • Gists are secret by default — pass public: true for publicly discoverable gists
  • gist_create accepts multiple files — useful for multi-file snippets
  • gist_get returns full file contents — use it to read existing gist code
  • Requires GITHUB_TOKEN with the gist scope

Safety

  • Confirm before gist_delete — deletions are permanent
  • Secret gists are accessible by URL but not searchable — they're not truly private
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
