cgpro: ChatGPT 5.5 Pro from the terminal

cgpro is a CLI that drives the user's authenticated ChatGPT session against chatgpt.com to expose GPT-5.5 Pro with extended thinking and live web search — capabilities that are not exposed by the public OpenAI API or by Codex CLI as of April 2026.

Use this skill when the user wants any of:

• A second opinion on a hard architectural / debugging question
• Extended reasoning on a problem that benefits from deliberation
• Live web search results with citations (current events, fresh docs)
• A multi-turn ChatGPT thread driven from the terminal

How to call it

cgpro is a single binary on the user's PATH. All calls are plain shell — use the Bash tool (or your platform equivalent) to run them.

Single question

cgpro ask "your question"

Streams the answer to stdout. Live web search is always on by default — policy choice for this CLI, freshness + sources matter more than determinism. Use --json for NDJSON event stream when you want to parse programmatically.

Long-running turns (>10 min)

GPT-5.5 Pro extended-thinking can take 5-30 min for non-trivial questions and over an hour for hard reasoning. cgpro defaults --timeout to 7200 (2 h). When invoking from a sandboxed shell (Claude Code Bash, IDE task runner, etc.) that has a per-call ceiling, use run_in_background and poll the output stream — the turn keeps running browser-side regardless of who's listening.

Multi-turn

cgpro auto-resumes the most recent shell-session conversation for 30 minutes, so back-to-back cgpro ask calls thread automatically. For an explicit multi-turn REPL, use cgpro chat. For a clean slate, pass --new-session.

cgpro ask "explain CRDTs in 3 bullets"
cgpro ask "now sketch a Rust trait for a state-based one"   # remembers
cgpro ask --new-session "totally different question"

Resume a saved conversation

cgpro thread list                 # local saved bookmarks
cgpro thread list --remote --refresh   # the chatgpt.com sidebar
cgpro ask --resume <name|uuid> "follow-up"
cgpro ask --save <name> "..."     # save the resulting thread under a name

Project routing (keep your Recents clean)

cgpro mirrors the current cwd into a ChatGPT Project so conversations land there and out of the global Recents list. Identity is the git remote (when present) or the cwd path.

cgpro project list              # remote projects + which one is linked here
cgpro project link "MyProj"     # link this cwd to an existing project
cgpro project show              # see linked project + recent convs + memory size
cgpro project digest            # ask GPT-5.5 to summarise recent convs into memory.md
cgpro ask "anything"            # auto-routes into the linked project,
                                # injects memory.md as preamble for new convs
cgpro ask --no-project "..."    # opt out of routing for one call

Project memory lives at ~/.cgpro/projects/<gizmoId>/memory.md and is appended (not overwritten) by digest.

Speed: daemon mode

Cold-starting Chromium adds ~5-10s per call. Start the daemon once and all subsequent asks use the warm browser:

cgpro daemon start    # one-time setup
cgpro ask "..."        # near-instant first token
cgpro daemon status
cgpro daemon stop

cgpro ask auto-detects the daemon. No client-side change needed.

When NOT to use cgpro

• Quick lookups Claude already knows. Don't waste a Pro turn on trivial questions.
• Tasks where the user wants Claude's own answer. If they ask you to do something, do it. Don't reflexively bounce to GPT-5.5.
• When cgpro status shows the user is not signed in. Tell the user to run cgpro login (interactive) or cgpro adopt (imports the desktop app's session). Don't try to authenticate yourself.

Health check

If cgpro returns Not signed in, Cloudflare challenge, or Selector broken, surface the error to the user — those need human intervention. For selector breakage, cgpro doctor audits the live DOM and points at the broken selector.

Conformance

cgpro uses the user's own ChatGPT subscription via the standard sign-in flow — same credentials, same session, same rate limits as the desktop app. Personal CLI use only.
