OpenAI harness-first plugin
stark AI Developer is a harness-first developer workflow toolkit for developers and coding agents: from a rough feature idea and existing code to an implementation-ready specification, architecture with transparent trade-offs, structural code findings, editable architecture diagrams, consistent repository documentation, and safely curated agent memory.
From daily work
The included skills are not a theoretical catalog for the store. They come from our daily work, are used multiple times a day, and are continuously improved. The plugin reflects the standard we apply to our own work and to every tool that analyzes or changes production code.
We chose open source deliberately: transparency about how it works and what it contains, room for your own adaptations, and a way to contribute feedback, ideas, and improvements. The package has no backend, MCP server, connectors, authentication, telemetry, analytics, hidden network calls, or runtime downloads.
Bundled in the plugin
Audit, review, clean up, and prune Codex memories.
Audit, review, clean up, and prune Codex memories. Use when the user asks about ~/.codex/memories, stale or noisy memories, memory pollution, cross-repo rule leakage, sensitive memory contents, memory config tuning, cleanup plans, or whether entries belong in memory, AGENTS.md, repo docs, skills, config, or deletion. Do not use for ordinary repo docs cleanup.
Interview, source-challenge, verify, save, and ADR-gate fuzzy coding requests into Codex-ready implementation specs.
Interview, source-challenge, verify, save, and ADR-gate fuzzy coding requests into Codex-ready implementation specs. Use when a feature, bugfix, refactor, migration, repo-wide change, or architecture task needs user-verified requirements, source-backed decisions, durable architecture decisions, acceptance criteria, validation commands, rollout notes, saved spec/ADR files, and a Codex execution prompt. Do not use when already fully specified or when the user wants direct implementation now.
Audit, create, transform, or animate verified logo pipelines for GitHub READMEs.
Audit, create, transform, or animate verified logo pipelines for GitHub READMEs. Use when a repository needs a new or reconstructed mark, motion specification, SVG animation master, executable animation recipe, static PNG, animated GIF, README-safe markup, reduced-motion fallback, or compatibility review. Do not use for unrelated app/site motion or generic image generation without a README branding target.
Set up repository-native ADR governance, audit architecture.
Set up repository-native ADR governance, audit architecture, or plan and execute ADR-guided refactors through intent-bound workflows. Use when work needs binding agent-facing ADRs, provider-to-local mapping, architecture PR review or drift, Next.js request patterns, source placement, backend/runtime/env/config boundaries, stack deviations, or bounded ADR-governed implementation. Do not use for tiny edits, generic framework education, or work with no architecture or governance consequence.

Set up, update, or diagnose CodeGraph and ast-grep so coding agents can use semantic repository scope and structural syntax evidence automatically. Use when a repository needs an idempotent CodeGraph/ast-grep installation, stable tool and index migrations, MCP reconnection, persisted agent guidance, or a read-only setup diagnosis.
Create, draw, generate, edit, verify, and export draw.io/diagrams.net `.drawio` diagrams.
Create, draw, generate, edit, verify, and export draw.io/diagrams.net `.drawio` diagrams. Use when the user asks for editable diagrams, flowcharts, architecture, sequence, ER/UML/state, BPMN, SysML, ML/DL, swimlane, timeline, network, icon-rich technical diagrams, or PNG/SVG/PDF exports; do not use for charts/plots or artistic image generation.
What the plugin is for
Turn rough feature ideas into implementation-ready specifications.
Compare software architecture options with explicit tradeoffs.
Search code structurally with CodeGraph and ast-grep workflows.
Create editable draw.io diagrams from system context.
Create repository documentation and animated README assets.
Curate durable Codex memory with explicit safety boundaries.

ChatGPT installs from the plugin page. Codex CLI still installs from this repository marketplace. ChatGPT and Codex share one Plugins Directory; there is no separate Codex website listing. A local install, GitHub release, or npx skills copy is not the ChatGPT plugin. The installing client still applies its own policies to your workspace and tools.
Codex 0.147.0 or later. Add the repository marketplace, then install stark-ai-developer. If more than one marketplace uses that name, pass --marketplace with the name from codex plugin marketplace list. In an interactive Codex session you can also run /plugins.
codex plugin marketplace add stark-ai-de/agent-skillscodex plugin add stark-ai-developerOpen the stark AI Developer plugin page in ChatGPT and install. Availability can still depend on account, workspace, and plan.
Use this only when you want the six workflows as separate catalog skills, not as the plugin. npx skills copies SKILL.md trees into a host. It does not add a ChatGPT or Codex plugin.
