OpenSpec Bulk Change Archiver
Fission-AI/OpenSpec
Archives several completed OpenSpec changes in one operation, checking the codebase to resolve spec conflicts rather than archiving blindly.
This skill should be used when the user asks to "build a feature", "create a spec", "start spec-driven development", "run research phase", "generate requirements", "create design", "plan tasks"…

What it does
Spec Workflow is an agent skill from tzachbon/smart-ralph. This skill should be used when the user asks to "build a feature", "create a spec", "start spec-driven development", "run research phase", "generate requirements", "create design", "plan tasks", "implement spec", "check spec status", "triage a feature", "create an epic", "decompose a large feature", or needs guidance on spec-driven development workflow, phase ordering, or epic orchestration.
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/phase-transitions.md`).
It sits in Development, covering Spec-driven development. The repository describes itself as: Spec-driven development with smart compaction. Claude Code plugin combining Ralph Wiggum loop with structured specification workflow. The licence is MIT.
When your agent uses it
- Asks to build a feature
- Start spec-driven development
- Run research phase
- Generate requirements
Example prompts
- “build a feature”
- “create a spec”
- “start spec-driven development”
- “/spec-workflow”
What it can do on your machine
Read from SKILL.md and the folder at commit ac7251a. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Spec Workflow loads about 1.1k tokens when it runs, and up to ~2.9k if it reads all its reference files. Until then it costs about 102 tokens; SKILL.md has 322 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Spec Workflow
Spec-driven development transforms feature requests into structured specs through sequential phases, then executes them task-by-task.
Decision Tree: Where to Start
| Situation | Command |
|---|---|
| New feature, want guidance | /ralph-specum:start <name> <goal> |
| New feature, skip interviews | /ralph-specum:start <name> <goal> --quick |
| Large feature needing decomposition | /ralph-specum:triage <goal> |
| Resume existing spec | /ralph-specum:start (auto-detects) |
| Jump to specific phase | /ralph-specum:<phase> |
Single Spec Flow
start/new -> research -> requirements -> design -> tasks -> implement
^
optional prototype overlay, then returnEach phase produces a markdown artifact under the resolved <basePath>/. Normal mode pauses for approval between phases. Quick mode runs all phases then auto-starts execution.
Prototype is an optional overlay, not a main phase. The main phase remains research, requirements, design, tasks, or execution; live prototype work is stored in activePrototypes. Resolve the configured spec root and basePath before any overlay operation. Follow references/phase-transitions.md when suggesting, starting, resuming, cancelling, or consuming prototype evidence.
Phase Commands
| Command | Agent | Output | Purpose |
|---|---|---|---|
/ralph-specum:research | research-analyst | research.md | Explore feasibility, patterns, context |
/ralph-specum:requirements | product-manager | requirements.md | User stories, acceptance criteria |
/ralph-specum:design | architect-reviewer | design.md | Architecture, components, interfaces |
/ralph-specum:tasks | task-planner | tasks.md | POC-first task breakdown |
/ralph-specum:implement | spec-executor | commits | Autonomous task-by-task execution |
/ralph-specum:prototype | prototype-builder | prototypes/<id>.md | Test one falsifiable design question in isolation |
Normal mode may suggest prototype after research or requirements, and the user owns capture, verdict, handoff, and deletion decisions. Direct invocation is available from any main phase. Quick mode runs at most one agent-owned request after requirements, takes over the oldest design blocker when one exists, asks no decision questions, and always continues to design.
Epic Flow (Multi-Spec)
For features too large for a single spec, use epic triage to decompose into dependency-aware specs.
triage -> [spec-1, spec-2, spec-3...] -> implement each in orderEntry points:
/ralph-specum:triage <goal>-- create or resume an epic/ralph-specum:start-- detects active epics, suggests next unblocked spec
File structure:
specs/
_epics/<epic-name>/
epic.md # Triage output (vision, specs, dependency graph)
research.md # Exploration + validation research
.epic-state.json # Progress tracking across specs
.progress.md # Learnings and decisionsManagement Commands
| Command | Purpose |
|---|---|
/ralph-specum:status | Show all specs and progress |
/ralph-specum:switch <name> | Change active spec |
/ralph-specum:cancel | Cancel active execution |
/ralph-specum:refactor | Update spec files after execution |
Common Workflows
Quick workflow
/ralph-specum:start my-feature "Build X" --quick
# Runs all phases automatically, starts execution
# May run one unattended prototype request after requirementsGuided development
/ralph-specum:start my-feature "Build X"
# Fact-first grilling at each phase
# Review and approve each artifact
/ralph-specum:implementLarge feature
/ralph-specum:triage "Build entire auth system"
# Decomposes into: auth-core, auth-oauth, auth-rbac
/ralph-specum:start # Picks next unblocked specReferences

When should I use Spec Workflow?
Spec Workflow fits situations like: asks to build a feature; start spec-driven development; run research phase; generate requirements.
How do I install Spec Workflow in Claude Code?
Run `npx skills add tzachbon/smart-ralph --skill spec-workflow -a claude-code`. Or copy the skill folder (plugins/ralph-specum/skills/spec-workflow in tzachbon/smart-ralph) into .claude/skills/spec-workflow in your project. Claude Code loads it when a task matches its description.
How do I install Spec Workflow in Codex?
Run `npx skills add tzachbon/smart-ralph --skill spec-workflow -a codex`. Or copy the skill folder (plugins/ralph-specum/skills/spec-workflow in tzachbon/smart-ralph) into .agents/skills/spec-workflow in your project. Codex loads it when a task matches its description.
Can I use Spec Workflow in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add tzachbon/smart-ralph --skill spec-workflow -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/spec-workflow, .gemini/skills/spec-workflow, .github/skills/spec-workflow and .opencode/skills/spec-workflow in your project.
What does Spec Workflow need to run?
SKILL.md names no scripts, command-line tools or credentials: Spec Workflow is instructions for the agent only.
Does Spec Workflow access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Spec Workflow safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Spec Workflow use?
Spec Workflow is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Spec Workflow use?
About 1.1k tokens (SKILL.md is roughly 4.6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 1.7k tokens, read only when the agent opens those files.
