How does it handle large or complex codebases?

The skill includes a recursive multi-pass mode that first creates a high-level territory map and a structured plan before processing individual subsections.

Does it overwrite my existing documentation?

No, if an existing spec is found, the skill performs a diff-style comparison and asks for human confirmation before applying any updates or merges.

What is the primary purpose of the Eidos Spec Puller?

It extracts the implicit logic and design decisions from your code and formalizes them into spec files, ensuring your documentation matches the actual implementation.

What is an 'Intent Sketch' in this workflow?

An Intent Sketch is a distillation of code into behavior claims that describe what a user experiences, designed to remain valid even if the underlying code is rewritten.

開発者ツール

Extracts high-level specifications and intent from existing source code to keep documentation in sync with implementation.

The Eidos Spec Puller is designed for Spec-Driven Development, allowing developers to reverse-engineer intent-based documentation from implementation code. It analyzes specific files, recent git changes, or project plans to identify implicit behaviors, design patterns, and architectural decisions, abstracting them into durable 'claims.' By bridging the gap between code and documentation, this skill helps teams maintain a source of truth that reflects the actual state of the software while focusing on high-level logic rather than low-level implementation details.
