Plugin code-modernization from marketplace claude-plugins-official in anthropics/claude-plugins-official. Commands read from the repo's manifest — today.

Slash commands (13)

• /code-modernization:modernize-assess

  What am I dealing with? Inventory, complexity, debt, security and a recommended modernization pattern

• /code-modernization:modernize-brief

  Write the phased Modernization Brief — the plan a steering committee approves and the build commands execute against

• /code-modernization:modernize-extract-rules

  Mine the business rules out of the code into testable Given/When/Then rule cards with file:line citations

• /code-modernization:modernize-harden

  Security scan of the legacy system with a reviewable remediation patch (OWASP, CWE, CVEs, secrets, injection)

• /code-modernization:modernize-map

  Show me the structure — dependencies, data flow, entry points and business flows, as an interactive map

• /code-modernization:modernize-preflight

  Run this first — checks the environment, records where the code lives, and says what to fix before anything else runs

• /code-modernization:modernize-reimagine

  Rebuild the system from its extracted intent on a new architecture, with two human checkpoints

• /code-modernization:modernize-review

  Confirm or correct the business rules that need a person's judgement; the plan and the build read your answers

• /code-modernization:modernize-status

  Where am I? Progress, what is stale, and the exact next command to run — start here when unsure

• /code-modernization:modernize-transform

  Rewrite one legacy module in the target stack, with tests that prove it behaves the same

• /code-modernization:modernize-uplift

  Same-stack version uplift (e.g. .NET Framework 4.8 to .NET 8, Java 8 to 17) — keep the code, fix the version deltas, prove nothing changed

• /code-modernization:modernize-verify

  Prove the modernized code behaves like the legacy, with an independent re-check and one verdict per module

• /code-modernization:modernize

  Start here — say what you want done with your code and get the plan and the first step

Subagents (8)

• architecture-critic

  Reviews proposed target architectures and transformed code against modern best practice. Adversarial — looks for over-engineering, missed requirements, and simpler alternatives.

• business-rules-extractor

  Mines domain logic, calculations, validations, and policies from legacy code into testable Given/When/Then specifications. Use when you need to separate "what the business requires" from "how the old code happened to implement it.

• legacy-analyst

  Deep-reads legacy codebases (COBOL, Java, .NET, Node, anything) to build structural and behavioral understanding. Use for discovery, dependency mapping, dead-code detection, and "what does this system actually do" questions.

• scaffolder

  Scaffolds one service of a reimagined system from the approved architecture and spec — project skeleton, domain model, API stubs, executable acceptance tests. Write access is scoped to its own service directory under modernized/.

• security-auditor

  Adversarial security reviewer — OWASP Top 10, CWE, dependency CVEs, secrets, injection. Use for security debt scanning and pre-modernization hardening.

• test-engineer

  Writes characterization, contract, and equivalence tests that pin down legacy behavior so transformation can be proven correct. Use before any rewrite.

• uplift-migrator

  Migrates ONE project/module of an in-flight same-stack version uplift by applying a proven pilot playbook — minimal diff, then runs that unit's real build to prove it. Refuses to migrate anything if no playbook exists yet. Write access is scoped to its own unit's directory inside the uplift working

• version-delta-analyst

  Identifies the breaking changes between two versions of the SAME stack (e.g. .NET Framework 4.8 → .NET 8, Java 8 → 17/21, Spring Boot 2 → 3) that actually bite a given codebase, and drives the ecosystem's migration tooling. Use for same-stack uplifts, where code is preserved and tweaked — not rewrit
