project-decomposition Skill
Single-source codebase decomposition: scans a project scope, builds the module dependency graph, counts LOC by language, computes skip patterns (caller-supplied ∪ .gitignore ∪ baseline), and (when grouping is required) produces topology groupings with L3 quality validation. One skill owns ProjectProfile JSON, grouping Published by microsoft in github-copilot-modernization.

Single-source codebase decomposition: scans a project scope, builds the module dependency graph, counts LOC by language, computes skip patterns (caller-supplied ∪ .gitignore ∪ baseline), and (when grouping is required) produces topology groupings with L3 quality validation. One skill owns ProjectProfile JSON, grouping Published by microsoft in github-copilot-modernization. This profile combines repository metadata with install, compatibility, and usage signals so developers can quickly decide whether it fits their agent workflow before opening the source repository.
Automated repository signals based on public metadata such as recency, license, installation evidence, and adoption. These are not a security audit or endorsement.

Skill instructions
Project Decomposition: Recon, Grouping & Validation What this skill does This is the single entry point for measuring a codebase scope and (when needed) decomposing it into topology groups. Two modes: 1. Lightweight recon (JSON) — scripts/decompose.py ... --profile-json produces a structured ProjectProfile JSON with LOC / file counts / module list / dep graph summary / skip patterns. Used by upstream planners to decide pipeline variant and grouping needs. 2. Full grouping + validation — scripts/decompose.py directly, for L0→L1→L2 grouping protocol and L3 quality validation. Used when the workflow plan declares grouping.needed: true. Both modes are the same decompose.py engine — single source of truth for LOC counting (--lang defines the LOC semantic boundary; --exclude defines the directory boundary), graph extraction, and validation scoring. Which mode to run | Caller intent | Use | Why | |---------------|-----|-----| | Decide whether to fan out at all (sizing, dispatch) | --profile-j
