CLARITYPRECEDESCODE.
An AI Senior Architect that uncovers edge cases and drafts the 4-file spec bundle your AI coding agents build from.
- constitution.md
- requirements.md
- solution.md
- tasks.md
The spec engine.
messy idea → structured interview → four sharp files

WHAT WE BUILD
PROMPT DRIVEN IS BROKEN. SPEC DRIVEN IS DETERMINISTIC.
See what happens when you replace vague chat prompts with immutable 4-file architectural contracts.
> "Wait, did you remember guest checkout shouldn't require an account?" Agent: "Apologies! Rewriting auth logic again..."
⚠️ Agents forget non-goals after 12 turns, invent non-existent APIs, and overwrite architecture.
// constitution.md (Locked Invariant) [INV-02] Guest checkout MUST NEVER require account creation. // MCP Server streams constraint directly into Cursor.
✓ Rules remain immutable across all agent prompts. Zero context degradation.

BEYOND EXPECTATIONS.
Leading software architects, engineering leads, and technical founders who refuse to let AI code without a blueprint.
“MySpec turned our chaotic prompt iterations into deterministic 4-file architectural contracts. Cursor and Claude Code follow every constraint without going off the rails.”
⚡Alex Rivera
Staff Architect at Hyperion Systems
“We value tools that feel stable, well thought out, and aligned with the standards we expect across our stack. MySpec lets our team ship with confidence rather than fixing unstated assumption bugs in production.”
🌀Elena Rostova
VP of Engineering at Vortex Cloud
“The senior architect interview catches edge cases before a single line of code is written. Our PR review time dropped by 65% because pull requests cite exact requirement IDs.”
💠Marcus Vance
Lead Systems Architect at Synthetix Labs
“Spec-driven development with MySpec has been a game-changer. It makes sure our AI coding agents build deterministic software without burning tokens on circular hallucination loops.”
🔷Chloe Dubois
Principal Engineer at Axiom Runtime
“Having our non-negotiables in constitution.md and acceptance criteria in EARS+ format gave our distributed team a single source of truth that humans and AI agents share.”
🚀Tariq Al-Mansoor
Founder at Kinetics Data
“The @myspec/mcp-server integration is seamless. We write specs in our browser, export to Git, and our IDE agents immediately pull structured context via stdio.”
