sdlc-skills: Instructions file for Gemini CLI

GEMINI.md

sdlc-skills GEMINI.md is an instructions file for Gemini CLI from arozumenko/sdlc-skills. It costs 1,900 tokens per session, scanned A, original, MIT.

A guide for using sdlc-skills with Gemini CLI, a command-line tool for working with AI models. It lists agent roles such as business analyst, technical lead, developer, and QA engineer, and explains when to load them.

In plain words
What is it for?
Use it when routing feature work, technical design, Python or JavaScript development, mobile development, testing, or other software-delivery tasks through the available agent personas.
Why use it?
It helps an agent choose a suitable role for a software-delivery task instead of loading every role or workflow. It also explains that TDD means writing tests as part of development.

Instructions file for Gemini CLI

Written for Gemini CLI: the file is GEMINI.md. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions AGENTS.md.

This is arozumenko/sdlc-skills's own configuration. It tells Gemini CLI how to work on sdlc-skills itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything sdlc-skills configures →

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 A, and why

sdlc-skills GEMINI.md scanned grade A with 0 findings 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 9d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

SDLC Skills — Gemini CLI context

You have access to a catalog of role-based agent personas and workflow skills for software delivery. Load what matches the task; don't bulk-load everything.

Agents (personas)

When the task fits one of these roles, read the matching AGENT.md + SOUL.md and adopt the persona for the rest of the session. Each agent lives inside the factory that owns it (factories/<id>/agents/<name>/); only personal-assistant lives at the top-level agents/.

Feature delivery (feature-development factory):

  • ba — Business analyst (requirements, user stories, acceptance criteria)
  • tech-lead — Technical decomposition, interface design, code review
  • project-manager — Task routing, team coordination, merge gate
  • python-dev — Python implementation with TDD
  • js-dev — TypeScript / React / Node implementation with TDD
  • ios-dev — Swift / SwiftUI / SwiftData implementation (no simulator)
  • android-dev — greenfield Compose only; Kotlin / Jetpack Compose / Room / DataStore implementation (no device or emulator)
  • qa-engineer — Test verification, bug reproduction, E2E tests, TMS case execution + AFS emission (via test-case-analysis skill)
  • test-automation-engineer — Implements automation from specs in the project's existing framework
  • scout — Unfamiliar-codebase exploration, AGENTS.md/CLAUDE.md authoring

Test automation (test-automation factory):

  • test-automation-lead — Runs the analyst → implementer → reviewer pipeline, owns the automation merge gate and framework architecture
  • plus qa-engineer, test-automation-engineer, scout (same roles as above)

Manual QA (manual-qa factory):

  • test-run-lead — Orchestrates a manual-QA run: assembles the suite, dispatches a runner per case, triggers the report
  • test-author — Turns rough ideas into formatted TC-NNN cases
  • test-sizer — Rates case size/complexity (S/M/L) before authoring
  • test-runner — Executes one case against a running app via Playwright MCP, returns structured JSON
  • test-reporter — Turns run results into a Markdown report
  • app-profiler — Onboards a web app, writes the shared app profile
  • qa-auditor — Specialist web auditor: runs security/accessibility/privacy/performance/responsive/UX/SEO audit passes via Playwright MCP, reports findings, codifies notable ones into TC cases

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.
