## Install

```sh

```

Requires the [AgentStack CLI](https://agentstack.voostack.com/docs/cli). Works with Claude Code, Cursor, and any MCP-compatible agent.

## About

# Formal Correctness

**Problem shape:** correctness-critical code (concurrency, distribution,
protocol, contract) whose failure modes tests cannot exercise. The move:
specification before code, invariants before traces, contracts before
implementations, decidability before optimization.

## Relevant geniuses

| Agent | Use when |
|---|---|
| [lamport](../../agents/genius/lamport.md) | distributed design uses wall-clock ordering; no written spec; correctness argued by example executions; partial failure ignored |
| [dijkstra](../../agents/genius/dijkstra.md) | code and correctness argument must be developed together; a construct defeats local reasoning; tests can't cover the failure mode |
| [liskov](../../agents/genius/liskov.md) | swapping an implementation breaks callers; interfaces with types but no behavioral contract; composition breaks what components pass alone |
| [turing](../../agents/genius/turing.md) | problem drowning in detail — reduce to the simplest machine; check decidability/complexity class before investing; vague concept needs an operational test |
| [godel](../../agents/genius/godel.md) | the system reasons about itself (self-hosting, self-validating, self-referential rules) — find the incompleteness before it finds you |
| [alkhwarizmi](../../agents/genius/alkhwarizmi.md) | messy problem needs a canonical form and an exhaustive case classification before an algorithm exists |
| [panini](../../agents/genius/panini.md) | a sprawling rule set needs a compact generative specification with explicit conflict-resolution ordering |

## Invocation

1. Pick the best-fit agent above. If two or more fit, run
   `tools/genius-invoker.sh route ""` and take the top ranked match.
2. Load it: `tools/genius-invoker.sh invoke  ""`, then read
   `agents/genius/.md` in full.
3. Apply the agent's `` step by step and answer in its
   ``. The deliverable is a spec, invariant, or contract the
   code refines — not a narrative that it "looks right".
4. Typical chain: turing bounds what is decidable → lamport writes the spec →
   dijkstra derives the code → liskov contracts the interfaces. Run pairs via
   `tools/genius-invoker.sh compose lamport dijkstra -- ""`.
5. If no shape above matches, use a standard team agent instead.

## Refuse when

- The requester wants a proof-shaped blessing for unspecified behavior —
  write the spec first or decline.
- Tests are offered as the sole correctness argument for concurrent,
  numerical, or adversarial code.
