AI SDLC — Stage tooling map

Version: 1.0.0
Date: 2026-07-29
Status: Working standard — operator map


Purpose

For each major delivery stage, name the AIES tools to run and how AI is leveraged — so teams stop guessing between a prompt, a skill, a pattern, and a chat.

Why

Prompts without a stage produce theater. Stages without tools produce “we use AI.” This page is the binding: stage → artifact → human gate.

How to use

  1. Identify the current stage (left column).
  2. Open the primary prompt.
  3. Activate the skill when the Why column matches.
  4. Escalate to a pattern when the change is consequential (multi-file, AuthZ, cutover, SEV).
  5. Keep MCP empty until MCP when and how allowlists it.

Major stages → tools

Stage How AI is leveraged Primary prompt Skill(s) Pattern (when consequential) Human gate
Idea / research Structure options; surface risks — does not decide product (workflow Idea) + story draft Planning Product owner locks problem
Requirements / DoR Turn intent into testable AC Story kickoff Context Context Definition of Ready
Context pack Curate trusted evidence for agents Kickoff context list Context · Security Context Trust labels reviewed
Planning Decision-complete execution contract Implementation plan Planning · Architecture Planner Named plan approval
Architecture Scenario-governed topology / ADR Architecture review Architecture · Security Architecture ADR + rejected alternatives
Coding Implement only against approved plan Coding Stack cookbook skill Planner → Coder handoff Diff stays inside planned paths
Self / agent review Severity-calibrated findings Coding self-review + Reviewer pattern Code review Reviewer Human owns merge
Testing Generate failing-first coverage Test generation Testing Tests gate merge
Security Threat pass on AI-touched paths Security review Security Reviewer / Enterprise Block on Critical/High
Performance Profile-guided changes Performance review Performance Optimization Baseline before change
Docs Capture decisions humans will need Documentation Documentation Docs in DoD
Release Progressive expose + abort Release DevOps · Evaluation Release Abort owner named; eval gate
Incident / hotfix Contain first; smallest reversible change Incident Debug · DevOps · Security Hotfix IC named
RCA / learn Evidence-bound cause + follow-ups Root cause analysis · Knowledge capture Debug · Documentation Root Cause Follow-up owners
Migration / legacy Phased cutover or strangler Migration Planning · Testing · DevOps Migration · Legacy Rollback owner per phase
Enhance harness Fit kit to this repo Enhance repo · create-prompt/skill/agent PR review of harness diffs

How AI is leveraged (rules of engagement)

Leverage Allowed Forbidden
Draft Plans, tests, docs, review findings Silent merges
Accelerate Boilerplate inside an approved plan Inventing AuthZ or schema
Detect Diff review, eval failures, incident signals Sole production authority
Propose ADRs with rejected alternatives Architecture-by-chat with no gate

Agent roles (when to escalate beyond a prompt)

Need Agent Notes
Multi-file plan Planner pattern agent No application code
Implement plan Coder Path-bounded
Review PR Reviewer pattern Human merges
Org / tenant AI Security · Enterprise pattern SoA first
SEV Incident response IC required

Tradeoffs

A stage map slows “just ask the chat.” It prevents silent scope expansion and unverifiable AI output. Teams that skip the map recreate private dialects and lose auditability.

Anti-patterns

  • Jumping to Coding before Story kickoff + plan approval
  • Using MCP write tools as a substitute for Release / Hotfix patterns
  • Treating evals as optional for user-visible model behavior
  • Claiming AI SDLC compliance because prompts exist in a wiki

Enterprise considerations

  • Stages 9 (plan), Security, and Release retain named human sign-off in regulated contexts.
  • Evidence artifacts (plan, review, eval report) feed SoA / portal — prompts alone are not evidence.
  • Data class constrains which MCP servers may enable at each stage.

Checklist

  • Current stage identified
  • Primary prompt opened from this table
  • Skill activated with a concrete artifact
  • Pattern used if change is consequential
  • Human gate named before irreversible effects
  • MCP still empty or allowlisted

Changelog

  • 1.0.0 (2026-07-29): Initial stage → tooling map with leverage rules.
