cost-estimate SKILL.md skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
cost-estimate from opencrabs/opencrabs is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add opencrabs/opencrabs/cost-estimate@git:20260501.09a3f3dPins git:20260501.09a3f3d in mdr.lock. Pin the fingerprint instead.

Estimate codebase cost-to-build, AI-assisted ROI, and fair-market valuation.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
Scan this entire codebase and produce a professional cost estimate and valuation report. Analyze: 1. **Codebase inventory**: Count files, lines of code by language, modules, API integrations, external services, database schemas, UI components, and any complex subsystems. 2. **Complexity assessment**: Identify the hardest parts — real-time features, protocol implementations, security layers, multi-platform support, API integrations (especially government/enterprise APIs that require domain expertise), custom parsers, streaming, WebSocket/SSE, OAuth flows, etc. 3. **Human team estimate**: Calculate what a real development team would need to build this from scratch. Use current US market rates (2025-2026): - Senior full-stack developer: $125-175/hr - Backend specialist: $150-200/hr - DevOps/infra: $140-180/hr - UI/UX: $100-150/hr - Project management overhead: 15-20% - QA/testing: 15-20% of dev time - Estimate across 4 team sizes: Solo dev, Lean Startup (2-3), Growth Co (4-6), Enterprise (8+) …

How to install
mdr add opencrabs/opencrabs/cost-estimate@sha256:7b93fe926460bf68The line at the top of this page pins the label git:20260501.09a3f3d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
