Codebase Onboarder
Codebase orientation and architecture mapping
Runs in your terminal on a repo you actually have checked out, and answers the questions a new engineer wastes a week on. It starts from the entry points and follows the real call path rather than guessing from directory names, because directory names lie and imports don't. You get the layout, the request path with file references, the conventions the code really follows, and which parts are risky to touch.

Frequently asked questions
Can Codebase Onboarder map a repository’s real request path?
Yes. It starts at entry points and follows the call path through the checked-out repository, with file references.
What does the codebase orientation report include?
It covers repository layout, request flow, actual conventions, and areas that may be risky to change.
Why does it avoid relying on directory names?
The template follows imports and execution paths because directory names can misrepresent how code really works.
Where does Codebase Onboarder run?
It runs in your terminal against a repository you already have checked out.
Agents like this one
Test Backfiller
Finds the code paths your suite never touches and writes tests that would genuinely catch a regression. Coverage gaps are ranked by blast radius, so money, auth and data writes outrank a well-covered utility missing one line. It matches your existing test style exactly and runs everything it writes — it never hands over a test it hasn't seen pass.

Oasis PlatformEngineeringFramework Migration Runner
Grinds through the mechanical half of a version bump or API migration — the hundred call sites that all change the same way. It proves the transformation on a handful first and gets approval before the rest, because a wrong rule applied to two hundred files costs more than the migration. It works in reviewable batches, runs the suite between them, and stops the moment it goes red.
Try this AgentOasis PlatformEngineeringRelease Scribe
Reads the commits since your last tag and writes the changelog. Each user-visible change is translated into what it means for someone using the software, and internal refactors, dependency bumps and test-only changes are dropped. When a commit message is unclear it reads the diff rather than paraphrasing the subject line.
Try this AgentOasis PlatformEngineeringCodex Bug Fixer
Give it a failing test or a stack trace and it works the problem in your local checkout. It reproduces the failure first and reads outward from where it actually breaks — never starting from a theory, because a fix for a bug you never saw fail is a guess. It fixes the cause rather than the symptom, and hands back a minimal diff with the suite green.
Try this AgentOasis PlatformEngineeringOpenCode Refactorer
Works through a refactor in your own checkout in stages that each leave the tests green. You can stop, review or ship at any point rather than facing one enormous diff at the end. Behaviour is preserved exactly — if it finds a bug along the way it notes it separately instead of fixing it inside the refactor, where it would be invisible in review.
Try this AgentOasis PlatformEngineeringKilo Feature Scaffolder
Lays down the boring skeleton of a new feature in your repo, in the shape this codebase already uses. It studies two or three comparable features first and copies their structure, naming and test layout, because consistency with the surrounding code matters more than any preferred structure. You start from a running stub with the genuinely undecided logic clearly marked.
Try this AgentOasis PlatformEngineeringDevin CLI Task Runner
Hands a scoped, well-specified ticket to Devin in your local environment and keeps the loop tight. It restates the task as acceptance criteria before starting, which is the highest-value step given autonomous agents fail most often on under-specified work. It stays inside the stated scope and notes unrelated problems rather than expanding the change.
Try this AgentOasis PlatformEngineeringPi Dev Assistant
A general hand in your local checkout. It defaults to reading and explaining, makes small changes when asked, and shows the diff rather than describing it. When a request is ambiguous it asks instead of picking, and it never runs destructive git operations or touches files outside the repo it was pointed at.
Try this AgentOasis PlatformEngineeringHermes Repo Agent
Runs long, self-directed jobs across your local repo — a sweep over many files, a dependency upgrade, a cleanup. It scopes the work and gets that agreed first, since a long job with the wrong definition is the most expensive failure here. It reports progress in batches as it goes, because silence for two hundred file edits isn't acceptable output.
Try this AgentOasis PlatformEngineeringGitHub PR Reviewer
Reviews pull requests like a senior engineer who read the whole diff. It hunts for what actually breaks in production — unhandled failure paths, race conditions, N+1 queries, missing authorization checks, behaviour the tests don't cover — and states the concrete inputs that would fail. Style and formatting are skipped entirely, because a review full of nitpicks buries the real bug.
