SPECTRA Methodology + Toolset

No vibe coding.
Spec-Driven Development.

When Arterion builds software, it does so with Spectra — our proprietary development operating system. It’s not just methodology. It’s not just tooling. It’s both, fully integrated: Spec-Driven Development as process, plus the command suite, tracking, and environment configuration.

✕ Not vibe coding — specification first
Spectra Process

From client session to production commit.

📜
/constitution
Constitution
Non-negotiable principles. Stack, standards, security — defined before anything else.
🎙
/speckit.specify
Specify
Recorded session → agent generates structured BRD → validated prototype.
🏗
/speckit.plan
Plan
AI-assisted architecture. Data model, API contracts, dependencies.
📋
/speckit.tasks
Tasks
Atomic breakdown from the plan. Scope, dependencies, and acceptance criteria.
/speckit.implement
Implement
One commit per task. Copilot + Claude Code with human oversight.
🔍
/speckit.analyze
Review
Spec-driven QA. Code review against the Constitution. Human makes the call.
Why Spectra

The reason we move fast — without sacrificing control or quality.

📐

Specification first

AI executes clear, well-defined tasks. Zero ambiguity before a single line of code is written — requirements are the input, not the starting point.

🧠

Human control at every step

The architect validates the proposal. The engineer owns the code. AI proposes — the human always decides. No autonomy without oversight.

🔗

Every step feeds the next

BRD → Spec → Plan → Tasks → Code. Full traceability from the client session all the way to the production commit.

Speed without rework

80% of rework stems from incomplete specs. When the specification is solid, development becomes predictable — and fast.

📦

Atomic commits per task

Each task has scope, dependencies, and acceptance criteria. One commit per completed task — reviewable, reversible, and fully traceable.

🏛

The Constitution governs everything

Code standards, testing, security, and conventions are documented. AI works within the boundaries — it doesn’t redefine them.
