spec-flow

A lightweight spec-driven development plugin for Claude Code. Guides you from requirements hearing through design, implementation, and verification with 5 skills centered around plan.md.

Install

/plugin marketplace add 884js/spec-flow
/plugin install spec-flow@884js-spec-flow

Workflow

(research) → spec → build → check → done
               ^                |
               |   (NEEDS_FIX)  |
               +----------------+

fix can be invoked independently at any time
list can be invoked at any time as a navigation hub

Step	Skill	Role
-	/spec-flow:list	Displays all plans with status and lets you navigate to any skill
0	/spec-flow:research	Technical investigation → research.md generation. Supports codebase analysis and web research
1	/spec-flow:spec	Requirements hearing → integrated analysis → direction confirmation → plan.md generation → browser review (Annotation Cycle) → progress.md generation
2	/spec-flow:build	Branch creation → task-by-task implementation → build verification → PR creation, all guided by plan.md
3	/spec-flow:check	Compares implementation code against plan.md and reports PASS / PARTIAL / NEEDS_FIX
-	/spec-flow:fix	Root cause investigation with no speculative fixes allowed. Supports feature mode and standalone mode

Skills

list

Displays all plans under docs/plans/ with status (in progress / not started / spec only / completed / verified) and lets you select a plan to edit, build, research, or check. Plans are sorted by priority — in-progress and not-started plans appear first. Supports pagination for large plan lists.

/spec-flow:list

spec

Completes everything from requirements hearing to technical design and implementation planning in a single command. Supports new mode (plan.md generation) and update mode (plan.md update from check results or additional requirements). Also generates progress.md for task tracking (single mode for small/medium, multi-pr mode for large features).

(research) → hearing → analysis → direction confirmation → plan.md generation
               → Annotation Cycle (browser review) → progress.md generation

After plan.md generation, offers an Annotation Cycle — a browser-based review loop:

1. A local server starts and opens the browser with the rendered plan.md
2. You add comments to sections, paragraphs, or selected text
3. Click "submit comments" → writer agent auto-revises plan.md
4. Browser re-opens with updated plan.md — repeat until satisfied
5. Click "review complete (no changes)" → cycle ends

/spec-flow:spec add user notification feature

Output: docs/plans/{feature-name}/plan.md + progress.md

build

Implements features guided by plan.md. Covers branch creation → task-by-task coding → build verification → PR creation. Supports pause/resume via progress.md state tracking. Detects spec gaps during implementation and prompts for spec update.

/spec-flow:build

check

Reads implementation code directly and detects deviations from plan.md bidirectionally. Reports results as PASS (all conditions met) / PARTIAL (minor mismatches) / NEEDS_FIX (significant mismatches), generating result.md. On NEEDS_FIX, proposes spec update to close the loop.

/spec-flow:check

fix

Prohibits speculative fixes and traces actual execution flows to identify root causes before proposing a fix. Operates in feature mode (with plan.md for spec correlation) or standalone mode (without plan.md).

/spec-flow:fix describe the error symptoms

research

Investigates technical topics through codebase analysis and web research. Outputs research.md with findings, comparisons, and recommendations. Results are automatically detected by /spec when creating a new spec.

/spec-flow:research authentication patterns for this project

Output: docs/plans/{feature-name}/research.md
