What Estimate does

Estimate analyzes task complexity, dependencies, historical velocity, and risk factors to produce a structured effort estimate with confidence levels. Use it before committing to a task to get optimistic, expected, and pessimistic day ranges plus a recommended budget and risk breakdown.

Estimate is cataloged under Data on DirSkills. Estimate comes from a repository tagged ai-agents, ai-assisted-development, anthropic, claude and claude-code.

Documentation

README

Phase 1: Understand the Task

Read the task description from the argument. If the description is too vague to estimate meaningfully, ask for clarification before proceeding.

Read CLAUDE.md for project context: tech stack, coding standards, architectural patterns, and any estimation guidelines.

Read relevant design documents from design/gdd/ if the task relates to a documented feature or system.


Phase 2: Scan Affected Code

Identify files and modules that would need to change:

  • Assess complexity (size, dependency count, cyclomatic complexity)
  • Identify integration points with other systems
  • Check for existing test coverage in the affected areas
  • Read past sprint data from production/sprints/ for similar completed tasks and historical velocity

This is the opening of the README. Read the full README on GitHub.

Frequently asked about Estimate

  • What else does Donchitos publish alongside Estimate?

    Estimate is one of 25 skills that DirSkills catalogs from Donchitos/Claude-Code-Game-Studios, the repository it ships in. Its siblings there include Adopt, Architecture Decision and Architecture Review. Each one is a separate skill with its own page in this directory, installs the same way Estimate does, and is maintained by Donchitos in that same repository. The rest of the collection is listed on the Donchitos/Claude-Code-Game-Studios page.

  • How does Estimate compare to other Data skills?

    Estimate ranks #82 by stars among the 668 Data skills in this catalog. The most-starred ones next to it are Benchmark Methodology, Jupyter Notebook and Solana. DirSkills ranks by the star count of the repository each skill ships in, so that order reflects how popular those repositories are rather than any review of Estimate against them. Open each page to compare what they document and how they install.

Adopt

Adopt audits a brownfield project's existing artifacts against the template's required internal formats, classifies gaps by impact, and produces a numbered migration plan. Use it when joining an in-progress project or upgrading from an older template version.

Architecture Decision

Architecture Decision creates an Architecture Decision Record (ADR) documenting a significant technical decision, its context, alternatives considered, and consequences. Use it when every major technical choice should have a formal, validated ADR in a game development project.

Architecture Review

Architecture Review validates that architectural decisions cover all game design requirements, are internally consistent, and target the correct engine version. It builds a traceability matrix, detects cross-ADR conflicts, and produces a PASS/CONCERNS/FAIL verdict.
