packmindhub Bundle

Produce proof-of-execution demos of the Packmind CLI (`packmind-cli`) as terminal-styled images (colors and formatting preserved exactly), for embedding in a GitHub PR. Renders a crisp master SVG and rasterizes it to a PNG — the PNG is what you embed, because GitHub does not render SVG in PR/issue bodies. Use this whenever a dev task touches the CLI — new command, changed output, new flag, bug fix in terminal rendering — and the PR would benefit from showing the tool actually running. Trigger it when the user says "record a CLI demo", "show the command output", "add a terminal screenshot to the PR", "prove the CLI works", "capture the CLI", "demo the command", or whenever you finish CLI work and are about to open or update a PR. Default to running this for any PR whose diff includes CLI source, even if the user didn't explicitly ask for a screenshot — a CLI PR without a visual of the output is an incomplete deliverable.

b-open-io-prompts Bundle

Get an independent read-only second opinion at a commitment boundary, before substantive work on a hard task, when stuck or changing approach, or at a final review gate. Use for "consult the advisor", "get a second opinion", "ask codex", "ask Astra", "ask gpt-6-astra", "ask Fable", "ask opencode", or "ask a bigger model". The advisor returns guidance; the main session keeps execution and decision ownership.

b-open-io-prompts Bundle

Run local performance audits on a project without network calls. This skill should be used when the user says 'audit performance', 'check bundle size', 'find large images', 'check for heavy dependencies', 'run a perf audit', 'how big is my bundle', 'optimize images', 'find oversized assets', or before any performance optimization work. Also use when an agent needs baseline metrics before making changes. All scripts output structured JSON to stdout.

Use when building any system where email content triggers actions — AI agent inboxes, automated support handlers, email-to-task pipelines, or any workflow processing untrusted inbound email.
