OpenCode SDLC Wizard

Status: v0.8.1 (codex round-1 fixes — Google tier mismatch, canonical env names, cost-ladder freshness, validator addProps — on top of v0.8.0's free-tier-first picker + cost ladder + 5 new providers + schemas + validator + full template set + check subcommand) — 2026-05-05. Install with npx opencode-sdlc-wizard init, check upstream with npx opencode-sdlc-wizard check. Full SDLC loop is any-backend on both coder AND reviewer (zero Anthropic+OpenAI lock-in possible); detector now picks up free-tier-friendly providers (Cerebras free, NVIDIA NIM credits, Groq free, Google AI Studio quota) and the new --free-tier-first flag biases recommendations toward $0/mo paths. See docs/cost-ladder.md for the $0 / $20 / $200 budget breakdown. Phase B (backend matrix proof) and Phase C (hardware scout) deferred to follow-up releases. See HANDOFF.md for architecture decisions, PRIVACY.md for the tier model, and CHANGELOG.md for release notes.

SDLC enforcement for sst/opencode — the privacy-first, any-backend agent CLI. This wizard ports the same plan → TDD → self-review enforcement pattern from the Claude / Codex siblings into the OpenCode runtime, so users can get SDLC discipline against whatever model backend their privacy / compliance constraints allow — not just Anthropic.

Supported backends OpenCode already speaks (and we'll inherit):

• Local: Ollama, LM Studio, llama.cpp, vLLM, MLX (Apple Silicon)
• Enterprise: Azure OpenAI, AWS Bedrock, internal AI gateways
• Hosted OSS: Together, Groq, OpenRouter, Cerebras, DeepSeek-direct, NVIDIA NIM
• Standard: OpenAI, Anthropic, Google AI Studio (Gemini)

For a concrete cost-vs-capability map across these — including $0/mo, $20/mo, $200/mo budget paths and which model fits which job — see docs/cost-ladder.md.

XDLC Ecosystem (Sibling Projects)

This wizard is one of four sibling projects. Same enforcement philosophy, different agent / domain:

Package	Agent / Domain	What It Does
agentic-sdlc-wizard (repo)	Claude Code / SDLC	Plan → TDD → self-review for code, with hooks + skills + CI scoring
codex-sdlc-wizard (repo)	OpenAI Codex / SDLC	Same SDLC enforcement, ported to Codex CLI (writes .codex/ + AGENTS.md)
claude-gdlc-wizard (repo)	Claude Code / GDLC	Game Development Life Cycle — persona-driven playtest cycles, triangulated findings, ratchet-only-tightens
opencode-sdlc-wizard (this repo)	OpenCode / SDLC	Same SDLC enforcement, ported to OpenCode (writes .opencode/). Privacy-first, any-backend.

All four are part of the broader XDLC ecosystem — generalized lifecycle enforcement across agents and domains.

Roadmap

Tracked as ROADMAP #9 in the parent repo: BaseInfinity/claude-sdlc-wizard/ROADMAP.md.

Three phases:

• Phase A (current target): port hooks + skills + install.sh from Claude / Codex pattern. Ship v0.1.0.
• Phase B: backend matrix proof — run E2E SDLC scenario across local (Ollama + Qwen-Coder), enterprise (Azure OpenAI), hosted OSS (Together/Groq), and Anthropic baselines. Document which backends hold SDLC compliance.
• Phase C: hardware scout for the local-tier compute requirement (gaming laptop / Windows laptop / $200–400 rig / cloud GPU rental).

Capability floor

"Just works on every LLM" is the dream but not the spec. Small local models (7–13B) are expected to fail the full plan → TDD → self-review protocol — instruction-following, long-context reasoning, and tool-use are all load-bearing. The 30B+ code-tuned class (Qwen-Coder, DeepSeek-Coder) is the likely local sweet spot. A failed run on an undersized model is a capability result, not a port bug.

Install

From a target repo's root, the easiest path:

npx opencode-sdlc-wizard init

That's it. Equivalent to the longer manual form:

git clone https://github.com/BaseInfinity/opencode-sdlc-wizard /tmp/opencode-sdlc-wizard
bash /tmp/opencode-sdlc-wizard/install.sh

Both paths are supported. npx is preferred for first-time installs; git clone + install.sh is preferred when you want to inspect the bundle before merging it. Re-run with --force to overwrite customizations, --dry-run to preview without writing.

This non-destructively merges the wizard into your .opencode/:

• .opencode/plugins/sdlc-wizard.js (the OpenCode plugin shim)
• .opencode/hooks/*.sh (5 portable bash hooks)
• .opencode/scripts/{detect,configure}-backend.sh (privacy-first picker)
• .opencode/skills/{sdlc,setup-wizard,update-wizard,feedback}/SKILL.md
• AGENTS.md and PRIVACY.md at repo root

Existing customizations are preserved. Re-run with --force to overwrite.

Native npx opencode-sdlc-wizard init shipped in v0.3.0. The bash installer remains the inspection/scripting path.

Pick a backend (privacy-first)

# See what's reachable from this machine (privacy-first cascade)
bash .opencode/scripts/detect-backends.sh

# Or bias toward free-tier providers (NVIDIA NIM, Cerebras, Groq,
# Google AI Studio) before paid hosted/proprietary
bash .opencode/scripts/detect-backends.sh --free-tier-first

# Configure the highest-privacy tier you can use
bash .opencode/scripts/configure-backend.sh \
     --tier private_local --provider ollama \
     --model qwen3-coder:30b

# Or for a $0/mo free-tier setup (Cerebras free, sub-second inference):
bash .opencode/scripts/configure-backend.sh \
     --tier hosted_oss --provider cerebras \
     --model llama-3.3-70b

Four tiers, ordered by where your prompts travel:

Tier	Travels to	Examples
private_local	Stays on your machine	Ollama, LM Studio, llama.cpp, vLLM
enterprise	Your tenant	Azure OpenAI, AWS Bedrock
hosted_oss	Third-party host	Together, Groq, OpenRouter
proprietary	Vendor (Anthropic/OpenAI)	Claude, GPT

Detector probes PATH + env vars only — no network calls. Configurator merges non-destructively into opencode.json and refuses to clobber an existing model pin without --force. See PRIVACY.md for the Ollama walkthrough and verification checklist.

Tests

bash tests/test-bundle-integrity.sh   # bundle correctness
bash tests/test-plugin-shim.sh        # plugin ESM + bash hook validity
bash tests/test-install.sh            # installer non-destructive behavior
bash tests/test-backend-picker.sh     # detect/configure-backend behavior
bash tests/test-cli.sh                # npx CLI wrapper
bash tests/test-cross-model-review.sh # OSS-tier reviewer skill + script
bash tests/test-domain-templates.sh   # TESTING.md domain templates
bash tests/test-bundle-drift.sh       # bundle drift / mirror guards
bash tests/test-check-cli.sh          # check subcommand + staleness
bash tests/test-doc-templates.sh      # SDLC.md + ARCHITECTURE.md templates
bash tests/test-review-schemas.sh     # JSON Schemas + validator

Or npm test runs all eleven (270 tests).

Known limitations

• No UserPromptSubmit analog in OpenCode. SDLC BASELINE moves to AGENTS.md (loaded once per session) instead of repeating per prompt.
• Phase A only. Backend matrix proof (Phase B) and hardware scout (Phase C) deferred. The wizard installs and runs against any OpenCode backend; we just haven't yet measured SDLC-compliance scores across backends statistically.
• No upstream-sync workflow yet. Updates from the parent claude-sdlc-wizard are manual. Future releases will mirror the Codex sibling's .github/workflows/upstream-sync.yml pattern.
