v0.9.0 · two-brain workflow · source-available

One writes. One reviews. You decide.

A context-aware toolkit for Claude Code. Claude drafts the plan and the code — a second model reviews the plan before it's built and hunts for drift before it's committed. You stay in the conversation; the loop keeps the work honest.

The loop

Plan. Review. Build. Ship.

Two models trade the work back and forth until it converges on one verified end-state. Watch the flow move through each stage.

  1. 01
    Plan · writer

    Claude drafts

    The plan is written and piped to the reviewer — before a single line of code.

  2. 02
    Review · reviewer

    Codex hunts flaws

    It reviews the plan for bugs, security, and scope. Claude adjudicates and re-sends until it converges.

  3. 03
    Build · writer

    Stamp & write

    The approved plan is stamped to an immutable spec. Claude writes the code against it.

  4. 04
    Ship · reviewer

    Drift-hunter gate

    At commit, the diff is audited against the spec. Deviations get flagged before they land.

Converge one verified end-state · immutable stamped spec · every finding surfaced to you · Claude adjudicates the reviewer — you approve
Why two brains

The cheapest bug to fix is the one you never build.

One model grading its own work drifts. A second, independent reviewer — checking the plan and the diff — catches what a single context misses.

Catch flaws before code

The reviewer reads the plan, not just the diff — the cheapest time to catch a bad design is before it's built.

No silent drift

The diff is audited against an immutable, stamped spec — not anyone's memory of the conversation. What you approved is what ships.

You stay in control

Claude weighs the reviewer's findings — the reviewer advises, never silently blocks. And every finding is surfaced to you, so the final approval is always yours.

Magic triggers

No more remembering slash commands.

Claude listens to how you naturally talk and suggests the right tool at the right moment. You stay in the conversation; the tool finds you.

/docify
"write docs" "document this project" "explain the codebase"

Used once to transform a messy project into a professionally documented one. Every claim cited back to a source file.

/before
"add a feature" "refactor this" "integrate Y"

Steps in before you code to prevent architectural blindness — reads docs, surfaces prior decisions, runs the plan past the reviewer.

/decision
"choosing between X and Y" "going with A because…"

Captures technical trade-offs while the logic is fresh — so nobody re-debates the same choice in six months.

/ship
"ready to commit" "push this up" "done"

Triggered at the moment of achievement — runs the drift-hunter gate, syncs docs with the new code, drafts a why-focused commit.

/session
"wrap up" "see you tomorrow" "done for today"

Builds a contextual bridge — Monday-you knows exactly where Friday-you left off.

Under 60 seconds

Put two brains on a project
you care about.

It's markdown. It's idempotent. It's uninstallable in one command. Nothing to lose.

No sign-up. No telemetry. No lock-in. Starring helps us a lot.
