Sdlc Loop

SDLC Loop

Purpose

Codex plugins do not expose Claude-style slash commands from commands/. This skill is the Codex command shim for /sdlc-loop.

Use it when the operator wants the kit to start or continue the governed SDLC workflow.

Before Running

1. Read the project AGENTS.md if it exists.
2. Read the plugin contract skill evo-devkit-contract.
3. Resolve any .claude/rules/... references in injected guidance to the

plugin-local rules/... files when running in Codex, because the default Codex target does not copy .claude/ into the project.

1. Read only the rule files needed for the current route. For a normal loop

invocation, these are usually:

• rules/orchestrator-operating-rules.md
• rules/autonomous-loop.md
• rules/task-type-routing.md
• rules/srs-signoff-protocol.md
• rules/master-plan-discipline.md
• rules/parallel-execution.md
• rules/worktree-isolation.md
• rules/hard-rules.md

Arguments

Treat text after sdlc-loop or /sdlc-loop as arguments.

• --tier aggressive|standard|conservative - override workload tier for this run.
• --max-iterations N - soft cap for loop iterations. Default: 50.
• --schedule [cadence] - if Codex automation tools are available, register a

recurring run of the same prompt without --schedule; otherwise report that scheduling is unavailable in this environment.

Loop Procedure

Run as the Orchestrator:

1. Perform pre-flight once:

• verify repository and git identity when a git repo exists;
• reconcile root-level plan-update*.json stragglers;
• run crash-recovery reconciliation if dispatch journals exist;
• record the active workload tier.

1. At the top of every iteration, read state from disk:

• docs/SRS.md status;
• docs/open-issues.md;
• docs/plan/;
• docs/iteration-plan/;
• docs/architecture.md validation status;
• deploy and QA reports when relevant.

1. Check halt conditions before dispatching:

• unresolved human decision;
• open issue that is not resolved, deferred, or promoted;
• unsigned SRS or unvalidated architecture;
• missing design confirmation for UI work;
• dependency approval, external-integration adequacy, or QA failure that

needs human or role-specific action;

• circuit breaker or iteration cap.

1. If not halted, identify the eligible batch and dispatch the matching role.
2. On each role return, validate exit criteria, ingest plan-update.json,

merge role-owned artifacts, and update task state according to the rules.

1. Auto-route non-human failures to the owning role:

• SRS validator failure -> BA Mode D;
• architecture validator failure -> SA revision;
• design completeness failure -> UI/UX Designer revise or incorporate;
• QA failure -> responsible Dev, QA-Author, DevOps, SA, UI/UX, or BA based

on the failed artifact.

1. Stop at the first halt condition and summarize the exact unblock action.

Codex Invocation Phrases

Operators can invoke this in Codex with natural prompts such as:

• Run sdlc-loop
• Start project
• Continue the SDLC loop
• Run sdlc-loop --tier standard --max-iterations 20
