plan-bender

Structured planning pipeline for AI coding agents — from interview to implementation.

Install • Quickstart • How it works • Skills • Dispatch • Configuration • Docs

---

plan-bender turns vague product ideas into thin, dependency-ordered, agent-ready issues — and then drives an AI coding agent through them. It ships as two small Go binaries plus a set of agent skills (slash commands) that orchestrate the pipeline:

interview ──► PRD ──► thin-sliced issues ──► implementation ──► PR

It is not an agent runtime. It writes JSON and skill markdown; your agent (Claude Code, opencode, openclaw, or Pi) does the work. The pba dispatch loop fans out parallel git worktrees so multiple AFK issues can run concurrently.

[!NOTE] plan-bender is pre-1.0. The CLI surface is stable for day-to-day use but expect rough edges. Feedback and issues welcome.

Features

• Opinionated planning workflow — interview → PRD → issues → review → implement, each step a dedicated skill
• Thin vertical slices — hard max_points: 3 cap forces decomposition into tracer-bullet issues
• Autonomous dispatch — pba dispatch runs the implementation loop end-to-end with parallel worktrees, dependency-ordered merge-back, and lifecycle hooks
• JSON state — PRDs and issues live in .plan-bender/plans/<slug>/ next to your code, diffable and reviewable
• Multi-agent — emits skills for claude-code, opencode, openclaw, and pi
• Optional Linear backend — sync local issues with a Linear project; local JSON stays the source of truth
• Structured CLI — plan-bender-agent (pba) returns JSON for agents to consume; plan-bender (pb) is the human-friendly twin

Install

One-liner (macOS/Linux)

curl -fsSL https://raw.githubusercontent.com/jasonraimondi/plan-bender/main/install.sh | bash

Installs plan-bender and plan-bender-agent to ~/.local/bin and symlinks pb and pba.

With Go

go install github.com/jasonraimondi/plan-bender/cmd/plan-bender@latest
go install github.com/jasonraimondi/plan-bender/cmd/plan-bender-agent@latest

[!TIP] The Go install path won't create the pb / pba shortcuts. Symlink them yourself, or use the install script.

Verify

pb doctor

Quickstart

From the root of any git repo:

pb setup

This writes .plan-bender.json, generates skill files for the agents you've enabled, and (optionally) adds entries to .gitignore. It's idempotent — re-run anytime to regenerate skills after a config change.

Then, in your agent of choice, invoke the orchestrator:

/bender-orchestrator

The orchestrator reads your plan state and offers a menu of next actions: start an interview, write a PRD, decompose into issues, review, or implement.

How it works

plan-bender is a methodology made executable. Each phase has a dedicated skill the agent runs; each skill calls the pba CLI to read or write structured JSON.

Phase	Skill	Output
Discovery	/bender-interview-me	Stress-tested idea, surfaced assumptions
PRD	/bender-write-prd	prd.json with scope, decisions, validation
Decomposition	/bender-prd-to-issues	Thin-sliced issues with dep graph and tracks
Review	/bender-review-prd	Principal-engineer pass with auto-fix
Implementation	/bender-implement-prd	pba dispatch runs all AFK issues
HITL issue	/bender-implement-hitl	Resolve human decisions, then AFK or implement
Single issue	/bender-implement-issue	Branch → code → test → PR

Plan layout

.plan-bender/plans/auth-system/
  prd.json
  issues/
    1-setup-middleware.json
    2-add-token-refresh.json
    3-add-role-checks.json

A minimal issue:

{
  "id": 1,
  "slug": "setup-middleware",
  "name": "Set up authentication middleware",
  "track": "rules",
  "status": "todo",
  "points": 2,
  "labels": ["AFK"],
  "blocked_by": [],
  "blocking": [2, 3],
  "tdd": true,
  "acceptance_criteria": [
    "Valid JWT → user context on request",
    "Expired JWT → 401"
  ],
  "steps": [
    "Auth middleware — reject malformed Authorization header",
    "Auth middleware — decode JWT, verify signature and expiry"
  ]
}

track is intent | experience | data | rules | resilience. points is hard-capped at max_points (default 3). labels use AFK (autonomous) or HITL (needs human input).

See docs/schema.md for the full schema.

Skills

Slash commands generated by pb setup into the per-agent skill directory. Call /bender-orchestrator to be guided, or invoke any step directly:

Skill	What it does
/bender-orchestrator	Menu-driven entry point — lists active plans and next actions
/bender-interview-me	Stress-test an idea before writing anything
/bender-write-prd	Interview + explore codebase + write prd.json
/bender-write-issue	Create a single issue
/bender-prd-to-issues	Decompose PRD into thin vertical-slice issues
/bender-review-prd	Principal-engineer review with auto-fix
/bender-implement-prd	Run pba dispatch to work all issues in dependency order
/bender-implement-hitl	Resolve human-gated issues and either hand back to AFK or implement now
/bender-implement-issue	One issue end-to-end: branch, code, test, PR
/bender-sync-linear	Sync plan with Linear (Linear backend only)

Autonomous dispatch

pba dispatch <slug> is the autonomous loop behind /bender-implement-prd. It:

1. Resolves an integration branch from pipeline.branch_strategy (integration creates <git-user>/<slug> off the default branch; direct merges straight to default).
2. Computes the next batch of unblocked AFK issues.
3. For each issue: creates a worktree → atomically claims it (status: in-progress + branch:) → runs before_issue hook → spawns claude --print in the worktree → runs after_issue hook.
4. Per-subprocess transcripts stream as [issue-N] … and land in .plan-bender/logs/<slug>/<id>.log. Each subprocess is capped by pipeline.subprocess_timeout (default 30m).
5. Merges successful branches into the integration branch in dependency order, flipping each merged issue to done. Conflicts mark the issue blocked and abort.
6. Runs the after_batch hook in the repo root.

[!IMPORTANT] Dispatch refuses to run with a dirty working tree. It captures and restores HEAD on exit so a successful run never silently leaves you on the integration branch.

Exit codes: 0 (all done) • 2 (only HITL issues remain — run /bender-implement-hitl <slug>) • 1 (failure — stuck-on-blocked, dirty repo, etc.)

Recovering from a stuck dispatch

pb status <slug>            # see per-issue state and failure notes
# fix the underlying problem
pb retry <slug> <id>        # flip blocked → todo (appends transition note)
pb dispatch <slug>          # resume

Configuration

Three layers, deep-merged (later wins):

File	Scope
~/.config/plan-bender/defaults.json	Global, shared across projects
.plan-bender.json	Project, committed to repo
.plan-bender.local.json	Local, gitignored — secrets go here

A minimal project config:

{
  "plans_dir": "./.plan-bender/plans/",
  "max_points": 3,
  "agents": {
    "claude-code": true,
    "pi": true
  }
}

For the full reference (tracks, workflow states, hooks, custom fields, Linear, templates) see docs/configuration.md, or print it inline:

pb docs --full

Supported agents

Agent	Skill directory	Scope
claude-code	.claude/skills/	Project or user
opencode	.opencode/skills/	Project or user
openclaw	~/.openclaw/skills/	User only
pi	.pi/skills/	Project or user

Linear integration

Drop credentials in .plan-bender.local.json (gitignored — never commit them):

{
  "linear": {
    "enabled": true,
    "api_key": "$LINEAR_API_KEY",
    "team": "$LINEAR_TEAM_ID",
    "project_id": "",
    "status_map": {
      "in-progress": "In Progress",
      "in-review": "In Review"
    }
  }
}

$VAR / ${VAR} are expanded at load time. Then sync:

pb sync linear push <slug>     # local JSON → Linear
pb sync linear pull <slug>     # Linear → local JSON

Local JSON remains the source of truth; Linear mirrors it.

CLI reference

pb is the human CLI; pba (plan-bender-agent) emits JSON and is what skills shell out to.

pb setup                       # idempotent — write config + regenerate skills
pb next <slug>                 # recommended next issue
pb status <slug>               # per-issue state + failure notes
pb dispatch <slug>             # autonomous loop
pb complete <slug> <id>        # flip to in-review (used by sub-agents)
pb retry <slug> <id>           # blocked → todo, clear notes
pb worktree create <slug> <id> # branch + worktree for one issue
pb worktree gc <slug>          # clean up merged branches/worktrees
pb sync linear <push|pull> <slug>
pb doctor                      # verify install
pb self-update                 # update to latest release

Full table (including every pba subcommand and JSON shape) in docs/cli.md.

CI

The locksafe workflow runs go run ./tools/locksafe/cmd/locksafe ./...; maintainers should mark this check required for PR merges in GitHub branch protection or rulesets.
