Agentic Software Engineering (ASE) is the opinionated Open Source toolkit of prolific author Dr. Ralf S. Engelschall, for fusing the concept of Agentic AI Coding and traditional Software Engineering . ASE ships as a plugin for the software development tool Anthropic Claude Code CLI — and with reduced support also for the alternative tools GitHub Copilot CLI and OpenAI Codex CLI. It is comprised of agent hooks, parametrizable agent skills, an underlying Model-Context-Protocol (MCP) service and a companion Command-Line Interface (CLI).<br>▶Dr. Ralf S. Engelschall in a<br>studio interview on ASE

ASE incorporates reasonable methodology and automation aspects to support the daily, recurring tasks of a Software Developer and Software Architect . The comprehensive functionality spans from brainstorming ideas, searching the Web, asking foreign LLMs, discovering components, through evaluating alternatives, challenging statements, analyzing root-causes, managing tasks, grilling task plans, all the way to analyzing, fixing, refactoring, and crafting code, reviewing changesets, and many more.

Token and Time Optimization<br>Switch persona to cut down tokens and reading time<br>To reduce your overall output tokens and necessary reading time, switch the communication style of the LLM across five built-in intensity levels: from the decorative, eloquent, and explaining writer , the concise, factual, and accurate engineer (default), the layered, pyramid-structured journalist , over the brief, factual, and abbreviating telegrapher , down to the terse, rough, and stuttering caveman .<br>Claude Code<br>❯/ase-meta-persona engineer

Parametrized Brainstorming<br>Diverge, cluster, and shortlist new ideas<br>Turn a fuzzy topic into a focused shortlist: first diverge into a broad set of ideas, then converge by clustering and scoring them, and finally distill a ranked shortlist with a recommended direction to pursue.<br>Claude Code<br>❯/ase-meta-brainstorm --max-clarify=0 --min-ideas=20 clever and useful AI skills for software engineering

Root-Cause Analysis<br>Trace root-cause with Five-Whys method<br>Drill past symptoms to the real cause: the Five-Whys method iteratively asks "why?" to trace a problem or claim back to its root, optionally branching into multiple causal paths to widen the investigation.<br>Claude Code<br>❯/ase-meta-why --width=2 is the Decibel (dB) unit a logarithmic one?

Component Discovery<br>Discover the right components for your technology stack<br>Get methodical support in finding suitable libraries and frameworks to establish or extend your technology stack — grounded, not guessed, by taking into account the downloads per time, age of component, last update time, and GitHub stars.<br>Claude Code<br>❯/ase-arch-discover command-line option and argument parsing library

Multi-Criteria Decisions<br>Evaluate alternatives with a multi-criteria decision matrix<br>Compare alternatives the rigorous way: a weighted multi-criteria decision matrix turns a fuzzy "which is best?" question into a transparent, defensible verdict.<br>Claude Code<br>❯/ase-meta-evaluate Commander vs. Yargs vs. Optique, focus on popularity, features, ease of use, and TypeScript support

Play Advocatus Diaboli<br>Challenge your decision with an Advocatus Diaboli<br>Know the antitheses to your decision before others bring them up. Let the decision be challenged by a relentless Advocatus Diaboli and even get a resulting synthesis based on Dialectical Reasoning.<br>Claude Code<br>❯/ase-meta-diaboli --count=10 We should migrate the ASE project from TypeScript to Rust

Play Steelman<br>Strengthen your decision with a Steelman<br>Further improve the strength of your decision before others challenge it. Let the decision be fortified by a helpful Steelman into a stronger position that consolidates everything that genuinely strengthens it while honestly bounding where it holds.<br>Claude Code<br>❯/ase-meta-steelman --count=10 ASE is a useful Claude Code plugin

Document Distillation<br>Distill a document down to its ranked key points<br>Cut a long document down to its essence: distill it into a flat, importance-ranked list of key points, each with a salience rank, a rationale, and a verbatim, line-cited evidence snippet.<br>Claude Code<br>❯/ase-docs-distill --top=3 @plugin/meta/ase-format-spec.md

Document Proofreading<br>Analyze documents for spelling, punctuation, and grammar<br>Scan your documents for problems in spelling, punctuation and grammar. Optionally, let the documents be automatically corrected.<br>Claude Code<br>❯/ase-docs-proofread...
