DonnyClaude

The verified workflow engine for Claude Code.

Claude Code is excellent at generating code. It is weaker at long projects: context gets messy, /clear loses decisions, and the model can call a task "done" before tests, requirements, or security checks actually pass.

DonnyClaude wraps Claude Code in a durable planning layer and a deterministic verification loop:

• writes project state to .planning/ so work survives /clear and new sessions
• breaks large work into explicit phases with requirement and dependency gates
• routes work to scoped subagents: planners, implementers, reviewers, verifiers
• refuses to mark work complete until engine-backed checks pass

npx donnyclaude

One command installs the [Donny engine](#deterministic-gates-the-donny-engine), the skills and agents, coding rules for 13 languages, project hooks, and a curated MCP setup - then Claude itself walks you through your first project.

Why this exists

LLM coding tools are good at producing work. They are much worse at knowing when work is actually finished. The recurring failure modes:

• the model forgets project decisions after /clear
• long tasks turn into messy chat history instead of durable state
• one overloaded prompt tries to plan, code, review, and verify itself
• "looks good" replaces tests, security checks, and requirement coverage
• unfinished work gets marked complete because the model graded its own output

Most Claude Code setups are prompt packs: they change what the model is told, then still trust it to declare success. DonnyClaude is built around one idea: the model generates the work, but completion is decided by durable state, skeptical review, and deterministic gates.

What this changes on your machine

Everything installs under ~/.claude/ (user scope); nothing touches a project until you start one there.

• ~/.claude/skills/, agents/, commands/, hooks/, rules/ - the toolkit
• ~/.claude/donny/ - the workflow engine
• ~/.claude/bin/, cco-memory/, scrapers/, docs/, statusline.py, and a

skill-index registry (.donnyclaude-skill-index.json) - support tools

• ~/.claude/CLAUDE.md - a fresh machine gets the full operating guide; an

existing file gets only a clearly marked, idempotent standards block appended

• ~/.claude/settings.json - merged, with your original backed up to

settings.json.bak first

• MCP registrations for Context7 (live docs) and Playwright (browser), at user

scope

Existing settings are preserved, not clobbered. And you can inspect or reverse all of it:

npx donnyclaude --dry-run       # preview what install would change - no writes
npx donnyclaude doctor          # check installation health
npx donnyclaude diff            # drift between installed files and this version (exit 1 = drift)
npx donnyclaude uninstall       # remove every DonnyClaude-owned file; yours stay

uninstall accepts --dry-run, --yes, and --no-mcp. It removes only files this package ships, strips just the managed block from CLAUDE.md, leaves settings.json in place, and never touches anything you created yourself.

Quickstart

npx donnyclaude                 # install, then the setup wizard

# then, in Claude Code:
/donny-init                     # research -> requirements -> roadmap
/donny-plan-phase 1             # plan a phase (dependency + requirement gates)
/donny-execute-phase 1          # build it (parallel subagents, atomic commits)
/donny-verify-work 1            # conversational UAT
/donny-ship                     # open a PR once verification passes

Use /donny-progress any time to see where you are, /donny-autonomous to advance the whole roadmap hands-off, and /donny-help for every command.

Install as a plugin (experimental)

/plugin marketplace add d0nmega/donnyclaude
/plugin install donnyclaude@donnyclaude

The plugin surfaces the skills, commands, and agents through Claude Code's plugin system. The Donny engine, hooks, rules, and MCP registrations still come from npx donnyclaude - run that once first. Pick one distribution for the skill surface: a plugin install on top of a full npx install registers the slash commands twice.

A project under Donny keeps its state on disk, not in chat history:

.planning/
  PROJECT.md               # what is being built, and why
  REQUIREMENTS.md          # scoped requirements with IDs
  ROADMAP.md               # phases mapped to requirements
  STATE.md                 # current position, decisions, blockers
  phases/
    01-foundation/
      01-CONTEXT.md        # locked decisions from the discuss step
      01-01-PLAN.md        # executable plan with tasks and gates
      01-01-SUMMARY.md     # what was actually built
      01-VERIFICATION.md   # goal-backward verification report

How it works

Durable project state

Every non-trivial task writes requirements, roadmaps, phase plans, summaries, and verification reports to .planning/, so long-running projects survive /clear and new sessions. Subagents get a curated, isolated slice of that state rather than the whole transcript. The Context7 MCP supplies live library docs so the model codes against current APIs, and a global operating guide loads the coding and writing standards every session.

Specialized subagents

48 agents and 94 slash-command skills, each a deliberately engineered prompt with a single responsibility and a minimal tool grant: planners, implementers, reviewers, build-fixers, researchers, verifiers. The right prompt runs for the right job instead of one overloaded system prompt trying to do everything. Model-tiered execution (Opus for planning and verification, lighter tiers for mechanical work) keeps cost proportional to the task.

Deterministic gates: the Donny engine

Under the agents sits a deterministic Node CLI that checks the things a language model should not guess at:

• verify phase-verified - a phase ships only when its verification status is

actually passed, parsed from disk, never an LLM's say-so

• verify milestone-coverage - requirement coverage computed across plans,

summaries, and verifications, not hand-tallied

• verify threats-clear / security scan-secrets - open threats and leaked

credentials block the commit deterministically

• phase defer - a skipped phase is recorded honestly as deferred, never

silently marked complete

The verified delivery loop

discover -> plan -> execute -> verify -> ship -> repeat

The generator never grades its own work: a separate skeptical verifier checks goal achievement by running code, and beneath that sits the engine gate so the verdict cannot drift from the truth. Run one phase by hand, or hand the whole roadmap to /donny-autonomous and let it advance unattended.

Why not just CLAUDE.md?

CLAUDE.md is the right place for project instructions. DonnyClaude adds the workflow layer around it:

| Need | CLAUDE.md | DonnyClaude | |----------------------------------|-----------|-----------------------| | Persistent project memory | partial | yes, via .planning/ | | Phase-based roadmap | no | yes | | Specialized subagents | manual | included | | Deterministic verification gates | no | yes | | Requirement coverage checks | no | yes | | Autonomous phase loop | no | yes | | Installable, repeatable setup | no | one command |

Who this is for

DonnyClaude is for developers who use Claude Code on projects large enough that chat history stops being enough. It earns its weight if you:

• work across multiple Claude Code sessions on the same project
• use /clear often but need decisions and progress to survive it
• want phase plans, requirement coverage, and verification artifacts on disk
• want specialized agents instead of one giant prompt
• want Claude to stop marking work complete without evidence

It is probably overkill if you only use Claude Code for one-off edits, small scripts, or quick explanations.

Requirements

• Claude Code (the installer

installs it if missing)

• Node.js >= 20
• uv for the bundled research scrapers (optional; self-bootstraps on first run)

Optional tools

• Research scrapers (bundled) - a multi-source HTTP research digest. See

[docs/research-tools.md](docs/research-tools.md).

• Obsidian - a vault as durable memory. The installer offers to install it.

See [docs/obsidian-memory.md](docs/obsidian-memory.md).

• browser-harness - optional, for login-gated research. Installed

separately; see [docs/research-tools.md](docs/research-tools.md).

Known limitations

• DonnyClaude is intentionally heavier than a minimal Claude Code setup.
• The install modifies user-level Claude Code configuration under ~/.claude/.
• Re-running the installer refreshes DonnyClaude-owned files, overwriting local

edits to those specific files; your own skills and settings are untouched.

• Autonomous mode should be supervised on repositories you care about.
• Some optional tools (Obsidian, browser-harness) require separate setup.
• The project is early and needs more real-world test cases - see below.

Help wanted

The best way to improve DonnyClaude is to run it on a real repo and report where the workflow breaks. Especially useful:

• failing real-world examples
• missing verification gates
• better language-specific rules
• smaller install profiles
• plugin/marketplace packaging
• demo projects and terminal recordings

Credits and license

DonnyClaude is MIT licensed. The Donny engine began as a fork of the GSD workflow engine and has since diverged substantially - rebuilt around deterministic verification gates, model-tiered subagents, and a subagent-safe research path.

The optional browser-harness integration references browser-use/browser-harness (MIT, Copyright (c) 2026 Browser Use); it is not bundled, and all credit for that project belongs to its authors.
