sdlc-loop

A command entry point for running Evo Talos's governed software-development workflow. It can start or continue work and dispatch eligible tasks until a review checkpoint, called a gate.

In plain words
What is it for?
Use it to start or resume the SDLC loop, choose a workload tier, limit its iterations, or run it on a schedule.
Why use it?
It gives a project a repeatable workflow for coordinating development tasks instead of handling each task manually.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

sdlc-loop scanned grade C with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

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.
  4. 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.
  2. 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.
  3. 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.
  4. If not halted, identify the eligible batch and dispatch the matching role.
  5. On each role return, validate exit criteria, promote validated role-owned artifacts by path-scoped ingestion, apply plan-update.json, and commit artifacts + task-state updates together according to the rules. Record the resulting full commit SHA as finalization.state: finalized in the dispatch journal before cleanup. Remove registered Git worktrees with the git worktree remove --force command. Remove logical-role handoff-only directories with rm -rf -- .worktrees/<role>-<task-id>/. Then remove the journal last with rm -- .claude/dispatch-journal/<role>-<task-id>.json. The Bash guard permits only these path-bounded cleanup targets. The marker lets SessionStart safely collect residue when final cleanup is interrupted.
  6. 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.
  7. Stop at the first halt condition and summarize the exact unblock action.

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

sdlc-loop is a skill published in the GitHub repository evolplus/talos (8 stars, last pushed 28d ago), licensed Apache-2.0. It adds 73 tokens to every session and 1,012 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
