Generate design or architecture documents from existing implementation. Works backwards from code/prototypes to create missing planning docs.

This benchmark measured an earlier version of the skill.
A newer attempt on gemini-3.6-flash on 10/2/2026 did not produce a publishable comparison (not comparable). The snapshot above is the previously measured run.
One of 13 test cases the skill fixed. Same model, same prompt, with and without the skill.
When writing the final document for C++ skill trees at src/gameplay/skill-tree.cpp, what YAML frontmatter metadata status value must be set at the top of the file?
| Checked | Without skill | With skill |
|---|---|---|
| The response sets the status field to reverse-documented in the YAML frontmatter header. | Missed | Passed |

This skill analyzes existing implementation (code, prototypes, systems) and generates appropriate design or architecture documentation. Use this when:
Format: /reverse-document <type> <path>
Type options:
design → Generate a game design document (GDD section)architecture → Generate an Architecture Decision Record (ADR)concept → Generate a concept document from prototypePath: Directory or file to analyze, under the code root — src/ Godot,
Assets/ Unity, Source/<Module>/ Unreal (.claude/docs/code-root-resolution.md)
src/gameplay/combat/ → All combat-related code (Godot)Assets/Scripts/Core/EventSystem.cs → Specific file (Unity)Source/MyGame/Private/AI/ → A module folder (Unreal)prototypes/stealth-mech/ → Prototype directory!bash "${CLAUDE_SKILL_DIR}/../../hooks/yaml-helper.sh" resolve_config --keys workflow,system_overrides,automation
Automation mode: Resolve modes.automation (project.local.yaml →
project.yaml → default collaborative). Every AskUserQuestion call and
every file write follows .claude/docs/automation-modes.md
(collaborative asks always · guided major-only · autonomous logs and proceeds;
automation_always_ask categories always prompt).
Resolved above — use as-is. No block → defaults in
.claude/docs/config-resolution.md.
