Estimate

Batch estimate unestimated work items in the backlog or a specific sprint.

Arguments

Format: <project> [--cycle <cycle-name>] [--scale fibonacci|tshirt]

• project: Project name or identifier (required)
• --cycle: Specific sprint to estimate items in (optional, defaults to full backlog)
• --scale: Estimation scale — fibonacci (default) or tshirt

Parse from "$ARGUMENTS".

Process

0. Bootstrap connector — consult the connector-bootstrap skill. Probe ToolSearch for the Plane resource tools referenced below (project, cycle, workitem, project_estimate); their names are mcp__<server>__<resource>, never assume a specific MCP prefix. If multiple Plane instances are connected, ask the user which one to use. All formulas and rules come from the agile-fundamentals skill. Calls are written resource(action=..., ...).

1. Resolve project:

   project(action=list)
   

2. Get items to estimate: If --cycle specified:

   cycle(action=list, project_id) → find cycle
   cycle(action=list_workitems, project_id, cycle_id)
   

   Otherwise:

   workitem(action=list, project_id, pql='stateGroup IN ("backlog","unstarted")', fields="id,name,point,estimate_point,priority", per_page=100)
   

   Filter: items where point is null or 0 (PQL has no estimate field; follow next_cursor). If the project has an estimate system (project_estimate(action=retrieve, project_id)), estimates are written as estimate_point ids from project_estimate(action=list_points, project_id, estimate_id) — see the estimation skill.

3. Find reference stories (for calibration): Look for completed items with known point values to anchor estimates.

4. Estimate each item: For each unestimated item:

   • Present: name, description, priority
   • Analyze: components touched, unknowns, dependencies
   • Suggest estimate with reasoning
   • If scale is tshirt: show XS/S/M/L/XL then map to Fibonacci

5. On confirmation per item:

   workitem(action=update, project_id, workitem_id, point=<value>)
   

6. Flag oversized items: Items > 8 points → suggest decomposition with /decompose.

7. Summary: Total items estimated, total points, items flagged for splitting.

Example Usage

/estimate "TaskFlow"
/estimate "My Project" --cycle "Sprint 12"
/estimate "ShopFlow" --scale tshirt
