SpecDeck

SpecDeck helps teams turn product decisions into reviewed specs that give their team and coding agents full context. Specs combine foundational project context (glossary, decision log, technical context) with feature specs that include product sections, engineering design notes, and acceptance criteria. An AI agent reads ready specs, works out build order, and creates goals that humans or agents can claim. Agents claim each acceptance criterion as met or unmet on submission, and teams verify results and accept work. The page states it works with Claude Code, Codex, OpenCode, OpenClaw, and many more coding agents. A built-in AI Assistant lets product colleagues draft requirements, catch conflicting decisions, and refine specs in the browser. Work can be agent-led, supervised, or human-led. Data is stated to be encrypted and stored and processed in Europe (EU/EEA, UK, Switzerland).

• Foundational project context including glossary, decision log, and technical context
• Feature specs with product and engineering sections and acceptance criteria
• Acceptance criteria that agents mark met or unmet when submitting work
• Agent planning that reads specs and creates goals in build order
• Goals that humans or agents can claim, with assignment and status tracking
• Spec changes returned as reviewable diffs
• Integrations with Claude Code, Codex, OpenCode, OpenClaw, and many more agents
• Built-in AI Assistant for product colleagues to draft requirements and refine specs
• AI search by meaning across people and agents
• Shared spec library, spec templates, and organization-wide workspaces (Organizations plan)
• Data encrypted and stored and processed in Europe

Best suited for

• Software teams whose coding agents work from tickets and lack product context
• Product and design teams who want to write specs alongside engineering
• Small teams trying the spec-to-review workflow
• Organizations running multiple workspaces that share glossary and decision logs
