Same behavior as [/gco](../gco/SKILL.md) — read-only sub-agent for review, research, and investigation — but forces the free `gpt-4.1` model from the start. No Premium Requests consumed.

GitHub Copilot Cheap Mode

Same behavior as /gco — read-only sub-agent for review, research, and investigation — but forces the free gpt-4.1 model from the start. No Premium Requests consumed.

When to Use

Premium Request quota is low or exhausted on the Pro plan

The task is simple enough that opus-level reasoning is overkill

You want a deterministic "cheap run" with zero risk of Premium consumption

How It Differs from /gco

Model: gpt-4.1 (forced via GCO_MODEL=gpt-4.1) — not claude-opus-4.6

No fallback needed — gpt-4.1 is already the cheapest tier

Everything else (read-only enforcement, timeout, output handling) is identical

Process

Follow the exact same process as /gco, but prefix the gco-run.sh invocation with GCO_MODEL=gpt-4.1:

LOGDIR=$(node $HOME/.claude/scripts/get-logdir.js) mkdir -p "$LOGDIR" DATETIME=$(date +%Y%m%d_%H%M%S) SLUG="<short-topic-slug>" GCO_MODEL=gpt-4.1 \ bash $HOME/.claude/skills/gco/scripts/gco-run.sh \ "<prompt>" \ "$LOGDIR/${DATETIME}-gcoc-${SLUG}.md" \ "$LOGDIR/${DATETIME}-gcoc-${SLUG}-stderr.log"

Run as a background Bash task with 15-minute timeout.

Collect and Present Results

Read the output file

If empty or missing, check stderr log for errors

Synthesize and present findings to the user

Include the log file path for reference

Do NOT report "used gpt-4.1 because of no quota" — the user deliberately chose cheap mode, it's not a fallback.

Important Notes

Copilot cannot modify files — all writes are done by Claude Code

NEVER use ~ in paths — use $HOME

Output and stderr go to $LOGDIR/${DATETIME}-gcoc-* (timestamped)

If copilot is not installed, report "Copilot CLI not found. Install with: gh extension install github/gh-copilot"
