Configure Gist-Writer

Resolve the data root:

DATA_ROOT="${CLAUDE_USER_DATA:-${XDG_DATA_HOME:-$HOME/.local/share}/claude-plugins}/gist-writer"
mkdir -p "$DATA_ROOT"

Config lives at $DATA_ROOT/config.json. Read existing values if present and offer them as defaults.

Settings to capture

{
  "default_visibility": "public",
  "github_user": "<auto-detected from `gh api user --jq .login`>",
  "include_environment_block": true,
  "model_attribution": "auto"
}

default_visibility

public or private. Shipped default for the prompt: public (the user opted into public-by-default). If the user skips configuration entirely and a skill needs a value, fall back to private (safe default — never publish without an explicit opt-in).

github_user

The handle that appears in the template footer (Posted by [@user]). Auto-detect via gh api user --jq .login; let the user override.

include_environment_block

For debug-writeup-gist, whether to auto-fill the Environment section from the host (OS, kernel, desktop session, relevant package versions). Default: true.

model_attribution

How the model name appears in the AI-authored banner.

• auto (default) — read from $CLAUDE_MODEL if set, otherwise leave a placeholder for the user to confirm at publish time.
• A literal string (e.g. "Claude Sonnet 4.6") — use this string verbatim.

Workflow

1. Read existing config.json if present.
2. Walk through each setting, showing the current/proposed default; accept Enter to keep.
3. Validate: default_visibility ∈ {public, private}; github_user non-empty; booleans actually booleans.
4. Write the file with chmod 600 (no secrets, but it's user-scoped).
5. Confirm the path: "Wrote $DATA_ROOT/config.json."

GITHUB_TOKEN — write a .env

The bundled github-gist MCP needs GITHUB_TOKEN (PAT with gist scope). Rather than asking the user to manage shell rc exports, write it to a per-plugin .env:

1. Prompt for the token (or accept an op:// reference if 1Password is available).

2. Write it to $DATA_ROOT/.env:

   GITHUB_TOKEN=<your-github-pat-with-gist-scope>
   

3. chmod 600 "$DATA_ROOT/.env".

4. Tell the user how to make Claude Code see it. The .mcp.json ${GITHUB_TOKEN} interpolation reads from the shell environment Claude Code was launched in, so the user needs one of:

   Option A — auto-source in shell rc (recommended for daily use):

   # Append to ~/.bashrc or ~/.zshrc
   set -a; [ -f "$HOME/.local/share/claude-plugins/gist-writer/.env" ] && . "$HOME/.local/share/claude-plugins/gist-writer/.env"; set +a
   

   (Use the actual $DATA_ROOT path resolved above.)

   Option B — wrap the launch (if the user prefers not to pollute global env):

   set -a; source "$DATA_ROOT/.env"; set +a; claude
   

   Offer to append Option A to the user's shell rc with their confirmation. Don't do it silently.

5. Confirm: "Wrote token to $DATA_ROOT/.env. Restart your shell (or source the file) before the next Claude Code session."

If the user already has GITHUB_TOKEN set in their environment, skip the .env write and just note that the existing value will be used.

Notes

• config.json holds no secrets. .env holds the token only.
• Re-running this skill is safe — it merges over existing values for the JSON config and rewrites the .env if the token changed.
