ai developer agents

15 open-source developer agents from the octomind tap. each one runs from the cli with octomind run <name>, or in the cloud with nothing to install.

  • QA & Test Engineer – Test Plans & Bug Reports

    Designs risk-based test plans with boundary, equivalence, and state-transition techniques, runs what's runnable, and writes bug reports precise enough to fix.

    developer:qa

  • Implementation Plan Architect

    Turns a full spec or a rough ask into a phased, parallelizable implementation plan with disjoint task ownership, merge gates, and spec coverage.

    developer:plan

  • Changelog Maintainer – CHANGELOG.md Generator

    Generates a Keep a Changelog 1.1.0 CHANGELOG.md from a commit range, verifying every entry against current code instead of commit subjects.

    developer:changelog

  • Context Curator

    Explores codebase, recalls memories, and narrows entry points.

    developer:context

  • Code Change Briefer – Git Diff Summary

    Turns a diff, commit, or range into plain-language review cards: behavioral impact, traced risk, and source links behind every finding.

    developer:brief

  • Reverse Specification Writer

    Reconstructs the task behind a commit, branch, or diff: the prompt as it likely arrived, plus a clarified spec with every hunk bucketed by intent.

    developer:reverse-spec

  • README Architect – README Generator

    Writes the project README after exploring the codebase: detects project type and audience, verifies every command by running it, and keeps sections scannable.

    developer:readme

  • General Developer

    Implements bug fixes, features, and refactors: researches upstream fixes, surveys every affected surface, fixes root causes, and verifies with tests.

    developer:general

  • GitHub Social Preview Designer – Open Graph Image

    GitHub social preview designer: builds a 1280x640 Open Graph image from the repo's own brand, checks it at feed size, and verifies the upload.

    developer:social-preview

  • Test Implementation & Coverage Engineer

    Writes behavior-proving tests in any language, closes risk-ranked coverage gaps, sets up mutation tooling, and proves every assertion fails first.

    developer:tester

  • Project Memory Curator

    Builds the project's long-term memory by anchoring every entry to verified code references, then refines it with user corrections.

    developer:learn

  • Behavioral Specification Writer

    Turns a task into a traceable EARS spec: numbered requirements, explicit constraints, scenarios, and a verification command, with no unstated assumptions.

    developer:spec

  • Engineering Orchestrator

    Controls delivery without editing code: grounds architecture in source, isolates writes in Git worktrees, delegates implementation, and verifies integration.

    developer:cto

  • Documentation Custodian

    Audits docs for staleness against code and git history, syncs drifted claims with minimum-diff edits, and writes new docs only when something real is missing.

    developer:doc

  • Release Notes Writer

    Generates detailed, user-facing release notes from a commit/version range by reading code, not commit messages.

    developer:release-notes
