How It Works

From task to PR in four steps.

Describe the task

Give Plandex a plain-English task in your terminal. Complex, multi-file, and spanning any part of your codebase.

Agent plans & codes

Plandex maps your entire repo, creates a plan, and writes code across every file that needs changing — autonomously.

Test & debug loop

It runs your test suite, catches failures, and debugs in a loop until everything passes. No human needed mid-task.

Review & merge

Inspect diffs in a sandbox. Approve all, approve selectively, or roll back to any checkpoint — then merge.

Live Agent Log

Watch it think
through your code.

Every file read, every test run, every debug step — fully transparent. Select a task to see Plandex work through it live.

Refactor auth module to use JWT + refresh tokens

Migrate PostgreSQL schema — add audit logging tables

Fix all TypeScript strict-mode errors across monorepo

Build REST API with CRUD endpoints + OpenAPI docs

Capabilities

Built for the hard stuff.

Context Engine

2M token project understanding

Indexes entire repos with tree-sitter AST maps. Plandex sees every function, import, and dependency — at 20M+ directory scale.

❯ plandex load .

# Indexed 1,847 files · 2.1M tokens

✓ Context ready · tree-sitter map built

Diff Sandbox

Review every change. Rollback instantly.

All AI changes stage in a sandbox before touching your files. Approve selectively or revert to any checkpoint.

src/auth/session.ts — 2 changes

- const exp = '1h'

+ const exp = '15m'

+ const refreshExp = '7d'

return sign(payload, SECRET, {expiresIn: exp})

Autonomy

Full auto or step-by-step

Dial from hands-off full auto to granular step confirmation. Switch at any point mid-task.

Multi-Model

Best model for every stage

Mix Claude, GPT-4o, Gemini. No lock-in ever.
