From the source SKILL.md

Estimation is the act of predicting the future with incomplete information. It is inherently uncertain, and the only dishonest estimate is one presented without uncertainty bounds. The history of software projects is a history of estimation failure — the Standish Group's CHAOS reports consistently show that the majority of projects overrun their schedules and budgets. This is not because developers are bad at estimation; it is because human cognition systematically underestimates complexity, and organizational incentives systematically punish honest estimates.

What this skill does

Estimation Planning is a community-contributed Claude Code skill in the business-ops sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/estimation-planning/ and loads when your prompt matches the skill's trigger.
