Gist Code Share

When returning code:

1. If code is 10 lines or fewer, inline code block is allowed.
2. If code is over 10 lines, prefer GitHub Gist.
3. Default to secret gist unless user asks for public.
4. Return a short summary + gist URL; avoid pasting long duplicate code in chat.
5. Never publish secrets in shared code. If sensitive values are needed, use placeholders and tell user to fill them locally.

Required checks

• Verify GitHub CLI auth: gh auth status
• If not authenticated (or missing gist scope), ask user to run: gh auth login
• Keep behavior simple: do not auto-fallback to alternate sharing backends by default; prefer guiding user to configure GitHub properly.

Sensitive data policy (mandatory)

Before sharing code, scan for sensitive data and remove it.

• Never include API keys, tokens, passwords, private keys, cookies, session IDs, webhook secrets, phone/email PII, or absolute local secret paths.
• If code requires secrets, replace with placeholders, for example:
• API_KEY=""
• TOKEN=""
• .env entry with empty value
• Add a short note telling the user to fill placeholders locally after copying.

Update mode (same URL)

When user asks to modify previously shared code, prefer updating the same gist link (new revision) instead of creating a new gist.

Use:

./scripts/update_gist.sh <gist_url_or_id> <file> "<short description>" [public|secret] [lang]

Behavior:

• Keep the same gist URL.
• Save changes as a new revision.
• Return the same fixed 3-line response format.

Create a new gist only when:

• user explicitly asks for a new link, or
• existing gist is not editable by current GitHub account.

Create gist

Use:

gh gist create <file> --desc "<short description>"

If code is generated in-session, write it to a temp file in workspace first. Use language-appropriate extension (.py, .js, .ts, etc.) so Gist syntax highlighting works well.

With bundled script:

./scripts/create_gist.sh <file> "<short description>" [public|secret] [lang]

If has no extension, pass [lang] (for example python, typescript) so the script can upload with a proper extension.

Default behavior: do not use --web (automation-friendly).

Optional: use --web only when the user explicitly asks to open the gist in browser immediately.

Response format (fixed)

Always use exactly this 3-line format:

1. One sentence on what was shared.
2. Gist URL (separate line).
3. File: · Lines:

Example:

Shared the full script as a secret Gist for clean copy/paste.
