SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Speckit scope estimation eliminates guesswork by turning spec complexity into a structured effort forecast that teams can plan around.

Core Features & Use Cases

It analyzes requirement, scenario, integration, and task counts from your spec artifacts to produce a phase-based and requirement-based breakdown; it adds an explicit risk buffer and provides optimistic, realistic, and pessimistic outcomes; it supports team-aware calibration through user-supplied arguments like team size, experience level, time units, and confidence level.

Use Case: When planning a new feature, stakeholders can quickly answer how long implementation will take by basing the estimate on what is actually specified in spec.md, plan.md, and tasks.md.

Quick Start

Ask the skill to estimate effort by complexity, phase, and requirement using the requirements and tasks found in the current .specify/ directory.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I generate effort estimates from a project spec?▼

To generate effort estimates from a project spec, you analyze requirement counts, scenario counts, and integration mentions within spec artifacts to produce a phase-by-phase and requirement-by-requirement effort forecast.

What is a three-point estimate in scope planning?▼

A three-point estimate in scope planning provides optimistic, realistic, and pessimistic effort scenarios based on spec complexity, allowing teams to plan around structured effort ranges with an explicit risk buffer.

Can I calibrate project effort estimates based on team size and experience?▼

Yes, you can calibrate project effort estimates by supplying user arguments like team size, experience level, time units, and confidence level to adjust the data-driven forecast generated from your spec artifacts.

How do I calculate risk buffer for software implementation tasks?▼

Calculating a risk buffer for software implementation tasks involves analyzing technical decisions and task structures in spec files, then applying an explicit buffer to the optimistic, realistic, and pessimistic effort outcomes.

Does effort estimation work without a formal project plan?▼

Effort estimation primarily requires read-only analysis of a spec.md file, but it also utilizes optional plan.md and tasks.md files to generate a more accurate phase-based and requirement-based breakdown.
