What it does

When you ask it to estimate a task, the agent reads your project notes (CLAUDE.md), any related design documents and past sprint records, then scans the affected code files by counting lines and branching statements. It then produces a report with optimistic, expected and pessimistic day estimates, a recommended budget, a confidence level, risks, dependencies and a suggested task breakdown. It is read-only and does not change any files.

Great for

  • Engineering leads planning sprints for a game or software project that uses the Claude Code Game Studios setup
  • Developers who want a second opinion on how big a feature is before committing to it
  • Teams that keep design documents and sprint history in the repository so the estimate can be grounded in them

Skip it if

  • Projects with no sprint history or documented codebase: the estimate will be uncalibrated and low-confidence, so treat it as a rough guess (the skill itself says so)
  • Precise scheduling or commitments to clients: the output is heuristic, based on line counts and branch counts rather than measured complexity or real velocity data

Try asking

  • “/estimate add inventory trading between players”
  • “/estimate migrate the save system to the new file format”
  • “/estimate add a pause menu to the HUD”

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Give a specific task description; vague requests make the skill ask for clarification and produce lower-confidence estimates.
  • Keep design documents and sprint records in the repo so the estimate can use them; otherwise expect a Low confidence rating.
  • Treat the line and branch counts as rough signals, not measured complexity, and check the flagged risks before committing to dates.
