Ospec
OSpec turns AI coding sessions into document-driven change files committed inside your repo for full traceability
OSpec solves the failure mode where AI coding work evaporates into chat logs: forcing each requirement into one inspectable change, with proposal-through-review files and an archive step only after acceptance. The 1.0 release strengthens the pitch by wiring the Stitch preview plugin and Playwright-based Checkpoint validation into one path. Pick it if you already run Codex, Claude Code or Gemini; if you want a hosted dashboard, look elsewhere.

Skip OSpec if you want a hosted dashboard with seats and roles, a no-code web UI, or AI code generation that adds no process steps — this is a CLI plus a file-based change discipline inside your repo.
OSpec is free and open source, so there is no per-seat or per-usage charge to model — the real cost is the workflow step you add per change. That compares favorably to hosted agent platforms that bill per seat or per task, but you pay for it in discipline and in the Node toolchain you already need.

What is Ospec?
Ospec — OSpec turns AI coding sessions into document-driven change files committed inside your repo for full traceability. Best for Developers already working in Codex, Claude Code or Gemini who want repo-native traceability, Teams that need an inspectable audit trail for AI-assisted changes, Solo developers who want a short, structured loop without a hosted dashboard. Free to use.
OSpec is a document-driven workflow that gives AI-assisted development a paper trail. Instead of letting a feature request vanish into a chat window, you keep the proposal, tasks, state, verification and review for each change as files committed in your repository. One requirement maps to one active change by default, so scope stays visible and people (and the AI) can follow the work. The loop is deliberately short. Install the CLI with npm install -g @clawplays/ospec-cli, run $ospec to initialize the project, use $ospec-change to start a feature, bug fix or docs update, then $ospec archive once testing passes or deployment succeeds. AI-assisted init asks at most one short follow-up, and the archive step is gated on deploy and validation succeeding. It works with Codex, Claude Code, Gemini and direct CLI workflows rather than tying you to one assistant. Two plugins extend the core loop. Stitch generates a page preview for UI-heavy requests and produces matching code in the same pass, connecting to AI through Codex or Gemini so you review design and implementation together. Checkpoint validates app flows and critical paths before acceptance, using Playwright for automated UI checks and reusing Stitch exports where both are enabled. OSpec 1.0 tied the two into a single path from design preview through flow validation to delivery closeout. It targets developers already working in Codex, Claude Code or Gemini who want traceability committed beside the code, including open-source maintainers governing outside AI contributions. Compared with chat-only assistants or hosted spec tools, OSpec keeps the record in the repo and asks for a few explicit steps rather than disappearing into a SaaS dashboard.

Behind the verdict
AI coding assistants are great at generating code and terrible at leaving a record. OSpec's bet is that the fix is process, not another dashboard: commit the requirement, the tasks, the verification and the review as files, and the audit trail sits next to the code it governs. We'd reach for this when a change needs to be defensible later. When to pick it: you already live in Codex, Claude Code or Gemini, you want to see why a change was made and what was checked, and your team reviews AI contributions rather than trusting them blind. The one-requirement-one-change default is the part that earns its keep, because scope creep becomes visible the moment a second requirement tries to ride along. When to pass: if you want a no-code web UI, server-side real-time collaboration, or AI code generation with zero added steps, OSpec asks for exactly those steps and will feel like friction. It's a CLI-and-prompts workflow, so non-developers won't get far. The closest thing to an alternative is a hosted spec or project tool that tracks work in a SaaS board. The tradeoff is real: OSpec's files live where the code does and travel with every clone, but you give up the dashboard conveniences. Install is a one-liner (npm install -g @clawplays/ospec-cli), which keeps the barrier low for anyone comfortable in a terminal. Checkpoint is where I'd expect the most mileage. Using Playwright to walk critical paths before a change is accepted catches the runtime gaps that unit tests miss, and reusing Stitch exports means you aren't rebuilding UI fixtures. Caveat: the plugins assume you have Codex or Gemini wired up for Stitch, so budget time to configure before the loop pays off.
Models under the hood
as of 2026-10-25
Limitations
- OSpec installs as a CLI via npm (@clawplays/ospec-cli) and is used from a project directory, so there is a prerequisite Node toolchain.
- It does not generate or verify work on its own: it depends on external AI assistants such as Codex, Claude Code or Gemini, and its effectiveness tracks whichever assistant you connect.
- The workflow must first be initialized with $ospec before the change lifecycle applies, and the design and validation plugins (Stitch, Checkpoint) are optional add-ons rather than part of the core flow.
- Collaboration is file-based, so there is no server-side real-time co-editing.

GeneratedReal-world workflow fit
Concrete scenarios for the personas Ospec actually fits — and what changes day-one when you adopt it.
You npm install -g @clawplays/ospec-cli, run $ospec in the project directory to initialize via AI chat, then use $ospec-change to work a single requirement through proposal, tasks and verification files.
Outcome: You finish the feature and run $ospec archive after deploy, leaving a readable record of the change committed beside the code instead of buried in a chat log.
A UI-heavy change goes through the Stitch plugin for a page preview and matching code generated in one pass, then Checkpoint runs Playwright flow checks against the critical path before acceptance.
Outcome: Design review and implementation iterate together, and the runtime verification happens before the change is archived rather than after it ships.
An outside contributor submits an AI-assisted change; you read the proposal, tasks, state and verification files in the pull request and check the archived record against the deployment.
Outcome: You can audit how the code was produced without interviewing the contributor or reconstructing an AI session.
Use cases
- Initialize a project for AI-assisted development with $ospec in your project directory.
- Submit a natural language requirement and track it as one change committed in the repo.
- Use Stitch to generate a page preview and matching code for a UI-heavy change.
- Validate submission flows and critical paths with Checkpoint and Playwright before acceptance.
- Archive an accepted change after testing or deployment succeeds to keep the repo clean.
- Review proposal, tasks, state and verification files to audit how an AI change was built.
- Govern outside AI contributions to an open-source project with reviewable change files.
- Run a bug fix or documentation update through the same explicit change path as a feature.
Setup time & first value
How long it actually takes to get something useful out of Ospec — broken out by persona, not the marketing-page minute.
Solo developers with npm already installed: minutes from install to an initialized project, since AI-assisted init asks at most one short follow-up. Small teams: add time to agree on when a change may be archived. The Stitch and Checkpoint plugins take longer because Playwright and a Codex or Gemini connection need configuring.
Switching to or from Ospec
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From ad-hoc AI chat sessions: initialize the project with $ospec so subsequent work lands in change files rather than conversation logs.
- →From a generic issue tracker: keep the tracker for backlog, but move AI-assisted implementation into one active change with proposal and verification files.
- →From a hosted agent platform: install the CLI, initialize in your repo, and push change files through your normal review path.
- →From no formal process: run $ospec-change on your next feature, bug fix or docs update and archive it only after testing or deployment succeeds.
- ↗To a hosted agent platform: export or copy the change files you want to preserve; the repo record travels as plain files.
- ↗To plain Git workflow: the change files are already committed, so you can stop using the CLI and keep the history.
- ↗To another spec-driven tool: the proposal, tasks, state and verification files map onto most requirement documents.
- ↗To no process: simply stop running $ospec-change; existing archived records remain readable in the repository.
