pokayokay

AI-assisted development orchestration - A Claude Code and Codex plugin that orchestrates AI-assisted development sessions with configurable human oversight, bridging the gap between hands-on control and full automation through skills, hooks, agents, and integration with ohno for task management.

Features

  • PRD to Tasks - Automatically break down requirements into epics, stories, and tasks
  • Orchestrated Sessions - Work across multiple sessions without losing context
  • Human Checkpoints - Choose your autonomy level: supervised, semi-auto, auto, or unattended
  • Multi-Dimensional Auditing - Verify accessibility, testing, security, docs, and observability
  • 24 Specialized Skills - Route work to domain-specific workflows automatically
  • Evidence-Based Completion - Require fresh verification before "done", "fixed", or "passing" claims
  • Root-Cause Debugging - Reproduce, diagnose, and regression-test bugs before fixes are marked complete
  • Spike Protocol - Time-boxed investigations with mandatory decisions

Prerequisites

  • Claude Code v1.0.0 or later, or Codex
  • Node.js v18 or later (for ohno CLI)
  • Git (for version control integration)

Installation

The easiest way to install is with the setup wizard:

npx pokayokay

This interactive wizard will:

  1. Install the pokayokay plugin for Claude Code, Codex, or both
  2. Configure the ohno MCP server
  3. Initialize ohno in your project
  4. Wire runtime hooks where supported
  5. Optionally set up kaizen integration

Run npx pokayokay doctor anytime to verify your installation.

Manual Installation

<details> <summary>Click to expand manual steps</summary>

Claude Code:

# 1. Add the marketplace (one-time setup)
claude plugin marketplace add srstomp/pokayokay

# 2. Install the plugin
claude plugin install pokayokay@srstomp-pokayokay

Or from inside Claude Code REPL:

/plugin marketplace add srstomp/pokayokay
/plugin install pokayokay@srstomp-pokayokay

Codex:

# From this repository, create a local Codex marketplace entry and wire hooks.
npx pokayokay

# Then activate the plugin in Codex.
codex plugin install pokayokay

The Codex setup writes a local marketplace entry to ~/.agents/plugins/marketplace.json and adds a pokayokay-owned hook block to ~/.codex/config.toml. The hook block enables codex_hooks = true, routes tool lifecycle events to hooks/actions/bridge.py, and adds conservative PermissionRequest approval handling.

Required: ohno MCP Server

Add to your MCP configuration.

Claude Code (~/.claude/settings.json):

{
  "mcpServers": {
    "ohno": {
      "command": "npx",
      "args": ["@stevestomp/ohno-mcp"]
    }
  }
}

Codex (~/.codex/config.toml):

[mcp_servers.ohno]
command = "npx"
args = ["@stevestomp/ohno-mcp"]

Initialize ohno

npx @stevestomp/ohno-cli init
</details>

Quick Start

# 1. Run setup wizard (if not done already)
npx pokayokay

# 2. Restart your configured AI runtime to activate MCP server

# 3. Plan from a PRD or concept brief
/pokayokay:plan docs/prd.md

# 4. View kanban board
npx @stevestomp/ohno-cli serve

# 5. Start working
/pokayokay:work supervised

# 6. Audit completeness
/pokayokay:audit --full

For a quick one-off change, use /pokayokay:quick <task>. For a bug, use /pokayokay:fix <bug> so pokayokay reproduces the issue, records root cause, adds or identifies a regression test, and verifies the fix before completion.

Workflow Guarantees

pokayokay deliberately adds process where coding agents tend to drift:

GateWhat it preventsWhere it applies
Brainstorm gateVague tasks becoming wrong implementationsyokay-brainstormer, /work
TDD gateBehavior changes without tests/quick, yokay-implementer, domain skills
Systematic debuggingSymptom patches and guess-and-check fixes/fix, yokay-fixer
Spec then quality reviewGood-looking code that misses requirements/work task completion
Verification before completionUnverified "done/fixed/passing" claimsAgents, commands, handoffs
Finishing branchAmbiguous cleanup or accidental discardWorktree and branch completion

Audit Dimensions

The /pokayokay:audit command checks 5 dimensions:

DimensionLevelsDescription
AccessibilityL0-L5Is the feature user-accessible?
TestingT0-T4Test coverage and types
DocumentationD0-D4Code comments to user docs
SecurityS0-S4Input validation to hardened
ObservabilityO0-O4Logging to full telemetry
/pokayokay:audit                    # Quick (accessibility only)
/pokayokay:audit --dimension testing  # Specific dimension
/pokayokay:audit --full              # All dimensions

Parallel Execution

Run multiple tasks simultaneously for faster throughput:

# Run up to 3 tasks in parallel
/pokayokay:work semi-auto -n 3

# Adaptive sizing (starts at 2, adjusts based on outcomes)
/pokayokay:work semi-auto -n auto

Note: -p is reserved for the Claude CLI --prompt flag. Use -n for parallel count.

How it works:

  • Coordinator dispatches N implementer agents in a single message
  • Each agent works independently with fresh context
  • Results processed as they complete
  • Dependency graph prevents unsafe parallelization

Adaptive mode (-n auto):

  • Starts at 2 parallel tasks
  • Scales up (max 4) when tasks succeed consecutively
  • Scales down (min 2) when failures occur
  • Displays batch size changes during session

Recommended settings:

  • Default: 1 (sequential, safest)
  • Independent tasks: 2-3
  • Adaptive: auto (recommended for most sessions)
  • Maximum: 5

Tradeoffs:

  • Higher token usage (N concurrent contexts)
  • Potential git conflicts (auto-resolved when possible)
  • No shared learning between parallel agents

Token And Context Budgeting

pokayokay tracks subagent usage when runtime telemetry is available and prints it in the session summary. Use the numbers as a session-review signal, not as a hard billing source: some runtimes may report unavailable token counts.

Practical defaults:

Work typeToken-aware default
Tiny edit or support request/pokayokay:quick inline
Bug with unclear cause/pokayokay:fix with root-cause debugging before edits
Broad codebase questionExplorer/test-runner style agents before full pipelines
Clear implementation taskOne implementer, then spec/quality review
Independent backlog batch/pokayokay:work -n 2 or -n auto before larger fan-out

Codex skills use progressive disclosure, so keep skill descriptions concise and let references stay lazy-loaded. Claude Code and Codex subagents both preserve the main context, but they add separate model/tool work; spend that budget when isolation, review quality, or wall-clock speed is worth it.

Session Resume

Resume interrupted work sessions without losing context:

# Resume the last session, picking up where you left off
/pokayokay:work --continue

Loads tasks with saved WIP data from ohno, skips brainstorming for resumed tasks, and dispatches the implementer with previous context.

Headless Session Chaining

When context fills during auto-mode work, sessions can automatically chain — finishing gracefully and spawning a new session that resumes from WIP. This is configured in .pokayokay/config.json, with .claude/pokayokay.json still supported for existing Claude Code projects:

{
  "headless": {
    "max_chains": 10,
    "report": "on_complete",
    "notify": "terminal"
  }
}

Chaining requires an explicit scope to prevent runaway sessions:

# Scope to a story — chains will continue until story tasks are done
/pokayokay:work auto --story story-abc123

# Scope to an epic
/pokayokay:work auto --epic epic-def456

Chain reports are generated to .ohno/reports/. The max chains limit (default 10) prevents runaway execution.

Worktree Isolation

Tasks automatically run in isolated git worktrees based on type:

Task TypeBehaviorOverride
feature, bug, spikeWorktree--in-place
chore, docsIn-place--worktree
# Default: smart based on task type
/pokayokay:work

# Force worktree for a chore
/pokayokay:work --worktree

# Force in-place for a feature
/pokayokay:work --in-place

Story-based reuse: Tasks in the same story share a worktree, keeping related changes together.

On completion: Use finishing-branch to verify the branch and choose to merge, create PR, keep the worktree, or discard work.

Sub-Agents

pokayokay includes 14 Claude Code sub-agents that run in isolated context windows for verbose operations. The model column below reflects Claude Code agent frontmatter aliases (haiku, sonnet, opus).

AgentClaude model aliasPurpose
yokay-auditorSonnetL0-L5 completeness scanning (read-only)
yokay-brainstormerSonnetRefines ambiguous tasks into clear requirements
yokay-browser-verifierSonnetBrowser verification for UI changes (read-only)
yokay-design-reviewerSonnetPre-implementation design and codebase-pattern review (read-only)
yokay-explorerHaikuFast codebase exploration (read-only, 5-10x cheaper)

yokay-spec-reviewerOpusAdversarial spec compliance review
yokay-quality-reviewerSonnetCode quality review (after spec passes)
yokay-spike-runnerSonnetTime-boxed investigations
yokay-test-runnerHaikuTest execution with concise output

Codex Agent Model Behavior

Codex does not use the Claude haiku / sonnet / opus aliases from these Markdown agent files. In Codex, pokayokay currently relies on skills, hooks, and MCP integration. A Codex-native agent layer would use .codex/agents/*.toml files with OpenAI model IDs such as gpt-5.4, gpt-5.4-mini, or Codex models, plus optional model_reasoning_effort. If a Codex subagent omits model settings, it inherits the parent session model and reasoning effort.

Why Sub-Agents?

  • Context isolation - Verbose scan output stays separate from main conversation
  • Cost optimization - Lightweight Claude aliases are used for simple exploration and test-running agents
  • Enforced constraints - Read-only agents can't accidentally modify files
  • Parallel execution - Run multiple investigations simultaneously

Commands like /pokayokay:audit, /pokayokay:security, and /pokayokay:spike automatically delegate to the appropriate agent.

Brainstorm Gate

For ambiguous or under-specified tasks, yokay-brainstormer runs before implementation:

  1. Detects vague descriptions or missing acceptance criteria
  2. Explores codebase for context
  3. Produces clear requirements and technical approach
  4. Requests confirmation before implementation proceeds

This prevents wasted work from misunderstood requirements.

Two-Stage Review

After implementation, two sequential reviewers check the work:

StageAgentChecks
1yokay-spec-reviewerAdversarial spec compliance (requirements met? no scope creep?)
2yokay-quality-reviewerCode quality (well-written and tested?)

Stage 2 only runs if Stage 1 passes. Both must PASS before a task is marked complete, and the quality reviewer must cite fresh automated-check evidence or state why a check was unavailable.

Hook System

pokayokay includes a guaranteed hook system that executes actions at key lifecycle points through Claude Code and Codex hooks:

HookTriggerActions
pre-sessionSession startsVerify clean, pre-flight (unattended), recover
pre-taskTask startsCheck blockers, suggest skills, setup worktree
post-taskTask completesSync, commit, detect spike, capture knowledge
post-storyStory completesTest, story integration, audit gate
post-epicEpic completesAudit gate
on-blockerTask blockedNotification
pre-commitBefore git commitLint, check ref sizes
permission-requestCodex approval promptAllow obvious read-only/test/ohno commands, deny destructive/deploy commands
post-sessionSession endsSync, session summary, curate memory, session chain

Intelligent Hooks

Beyond lifecycle automation, hooks provide intelligent guidance:

ActionHookPurpose
suggest-skillspre-taskSuggests relevant skills based on task keywords
detect-spikepost-taskDetects uncertainty signals, suggests spike conversion
capture-knowledgepost-taskAuto-suggests docs for spike/research tasks
audit-gatepost-story/epicChecks quality thresholds at boundaries

Hooks are registered through the plugin system and routed by bridge.py. Claude Code loads plugin hooks from hooks/hooks.json; Codex setup writes equivalent hook wiring to ~/.codex/config.toml because Codex hooks are configured through config files. The ohno MCP server provides boundary metadata when tasks complete, enabling automatic detection of story/epic completion.

Codex approval handling is intentionally conservative. pokayokay may auto-allow read-only inspection, pokayokay tests, and ohno bookkeeping. Destructive, deployment, publishing, push, and history-rewrite commands are denied or left to the normal human approval flow.

Use /pokayokay:hooks to view and manage hook configuration.

See HOOKS.md for configuration and customization.

Spike Protocol

For high-uncertainty work:

  1. Time-box: 2-4 hours (max 1 day)
  2. 50% Checkpoint: Assess progress
  3. Mandatory Decision: GO / NO-GO / PIVOT / MORE-INFO
  4. Output: .claude/spikes/[name].md
