development-estimation
Use when estimating time, effort, or complexity for features or projects - provides structured estimation workflows with breakdowns, risks, and confidence intervals.
Best use case
development-estimation is best used when you need a repeatable AI agent workflow instead of a one-off prompt.
Use when estimating time, effort, or complexity for features or projects - provides structured estimation workflows with breakdowns, risks, and confidence intervals.
Teams using development-estimation should expect a more consistent output, faster repeated execution, less prompt rewriting.
When to use this skill
- You want a reusable workflow that can be run more than once with consistent structure.
When not to use this skill
- You only need a quick one-off answer and do not need a reusable workflow.
- You cannot install or maintain the underlying files, dependencies, or repository context.

# Development Estimation ## Overview Create consistent, defensible estimates by breaking scope into components, identifying risks, and providing confidence intervals. ## When to Use - Estimating feature or project scope - Providing effort or complexity estimates - Delivering risk-aware breakdowns Avoid when: - The task is trivial or a rough gut-check is sufficient - Requirements are unknown and need discovery first ## Quick Reference | Task | Load reference | | --- | --- | | Estimation workflow | `skills/development-estimation/references/estimate.md` | ## Workflow 1. Define scope and estimation type (time/effort/complexity). 2. Load the estimation reference for structure. 3. Break into components and dependencies. 4. Add risks and confidence intervals. 5. Deliver estimate with assumptions. ## Output - Estimate with breakdown and confidence interval - Assumptions, risks, and validation notes ## Common Mistakes - Estimating without clear scope - Ignoring risk and dependency factors - Overstating precision beyond available data
