USE CASE
SDLC Speed Is the Ceiling on Feature Velocity.
Most teams ship features in weeks because every phase has handoff friction. Flexor compresses each phase to its minimum-viable footprint - agents do the work, humans own the calls.
The Problem
Sequential Handoffs Kill Velocity
SDLC speed is the ceiling on fund-ops feature velocity. Most teams ship features in weeks because every phase has handoff friction - PM to engineer to QA to release manager. Each handoff adds a day. The compounding delay is where the 8–10 day average comes from.
The root cause is sequential execution of work that could be parallel. A data architect waiting for a PRD, a QA tester waiting for code, an observability engineer waiting for tests - each waits for the previous person to finish.
The Solution
The PRD is the Contract. The Agent DAG is the Execution Plan.
Flexor compresses every SDLC phase to its minimum-viable footprint, with agents doing the work and humans owning the calls. The PRD is the contract; the agent DAG is the execution plan; the HITL gates are the control surface.
| Phase | Owner | Skills / Agents | Time | HITL Gate |
|---|---|---|---|---|
| Triage | Requestor | project-manager | < 30 min | Gate 1: Triage Accept |
| PRD | Developer | /interview, tech-writer, product-manager | 0.5–2 days | — |
| Build | Developer | /git-ops prd-start, /project-team execute | 1–2 days | Gate 2: Plan Approval |
| Verify | Developer | /git-ops rebase + tests | ~30 min | — |
| Review | Reviewer | /review-pr, security-auditor | 0.5–1 day | Gate 3: Verification Accept |
| Merge & Deploy | (automated) | /git-ops master prs | < 30 min | — |
| Closeout | (automated) | /git-ops prd-end, tech-writer | ~15 min | — |
Three Gates. Three Points of Human Judgment.
Autonomy without accountability is risk. Every Flexor SDLC has three mandatory HITL gates where the human reviews the agent's output and decides whether to proceed. Agents do the work. You make the calls.
Requestor reviews the triaged task: problem, success criteria, scope, assigned agents, tier, and estimated timeline. Approve to proceed to PRD phase.
Reviewer reviews the execution plan before multi-agent build begins. The plan names every agent, every deliverable, every acceptance criterion. No surprises at the end.
Reviewer verifies the delivered artifacts against the PRD acceptance criteria. Feature flag set to live percentage. Retro triggers automatically on acceptance.
Non-Negotiables on Every PRD
These requirements apply across all phases, all agents, all teams. They are not optional and not skippable. They are encoded into every agent's behavioral substrate.
Observability mandatory from first commit - dashboards and alert rules before merge
Security review required for any code touching auth, crypto, PII, or external APIs
Feature flags required for all user-facing changes
500 LOC maximum diff per PR - large changes split into phased PRs
5-day maximum branch life - work that slips gets re-triaged
