CallMed AI
Autonomous Codebase Audits · Python

We call a medic to your codebase. It returns a clean PR by morning.

Symbiote, our multi-agent engine, maps your Python repository's dependency graph and delivers PEP 484 type hints and clean docstrings as a single reviewable Pull Request. No logic changes, no broken formatting, no broken locks.

We deliver the PR. Your team reviews and merges. We never touch your main branch.

Insertions across 19 files in a self-refactor run — zero broken dependency locks

The Mirror Pass

The boring work no one wants to do, done overnight.

Strict PEP 484 type hints

Every public function in your codebase gets comprehensive type annotations. Static analysis works. IDE autocomplete works. Linters stop screaming.

Clean, functional docstrings

Concise documentation injected for all core methods — parameters, returns, raises, yields. Tight enough not to bloat minimal scripts. Detailed enough to onboard a new engineer.

Nothing else touched

Mirror is non-destructive by design. Your execution logic stays untouched. Top-level formatting preserved. No surprise dependency rewrites.

Three steps
01 / Perception
Map the repository

Symbiote parses your repo into a typed AST graph and computes the dependency blast radius for every file. You get a free Reconnaissance Scan: missing type hints, undocumented functions, fragile call paths.

02 / Reasoning + Action
Run the Mirror Pass

The Mirror agent rewrites each file under Bouncer-mediated file locks, with collision-free guarantees logged to a nanosecond-precision audit trail (kernel.log). All work happens on a dedicated branch.

03 / Delivery
Reviewable PR

You receive a single Pull Request on a symbiote/plan-{id} branch. Your engineering team reviews and merges. We never push to your main branch. You own every commit.

Safety architecture

Built for codebases that can't afford a silent break.

Bouncer concurrency control

Every write is preceded by a granted lock with transitive blast-radius checking. Two agents physically cannot modify overlapping dependency chains simultaneously.

Full audit trail

kernel.log records every lock acquire, wait, release, and denial with monotonic-nanosecond timestamps. Every run ends with a verdict line: COLLISION-FREE ✓ or COLLISION DETECTED ⚠.

Zero data retention

Code snippets transit OpenAI's enterprise API tier with zero data retention. Your proprietary code is never used to train future models. Full NDA available.

Branch isolation

Every mutation lives on its own symbiote/plan-{id} branch. We never touch main. Worst-case rollback is a single git branch -D.

Flat fee. PR-or-refund.

AI Systems Architect based in Aarhus. CallMed AI is a one-person + AI agency. I built Symbiote from scratch in 2025–26 to solve the hardest problem in autonomous code mutation: governed, collision-free concurrent execution. Every audit ships under my personal sign-off.

One free Reconnaissance Scan tells you if it's worth your time.

Send a Python repository URL. Within 24 hours you get a free map of its dependency blast radius, missing type hints, and undocumented functions — plus a fixed quote for the full Mirror Pass if you want to proceed.
