Solo Agentic Delivery Process (Node + TypeScript)

0) Prepare

• Node 22 LTS via mise (mise.toml), package manager pnpm 10, strict TypeScript, ESLint (flat), Prettier, Vitest, fast-check, Zod.
• Turn on branch protection + required status checks in GitHub. Enforce PRs, linear history, required reviews (self-review allowed but deliberate).

1) Specify (SPEC-first)

• Use /spec-feature Claude command to create a GitHub issue with Gherkin specification
• Define clear scope, non-goals, risks, and acceptance criteria (Given/When/Then)
• Prefer executable specs via tests

2) Plan & slice

• Break work into increments that take <1 day and can be merged behind a feature flag if needed.
• Draft a verification plan in your PR (template provided).

3) Generate with agent

• Author a task prompt in prompts/tasks/*.md referencing SPEC and constraints. Keep tool rights minimal.
• Use the agent to produce the smallest viable diff plus tests. Prefer in-repo prompt files (versioned).

4) Verify automatically

• Run: typecheck → lint → unit + property tests → contract validation (Zod/OpenAPI) → OSV scan → SBOM generation.
• CI enforces gates; artifacts include coverage report, SBOM, and SLSA provenance.

5) Review

• Self-review the diff. Check the "AI usage" block in PR. Ensure tests truly fail when behavior regresses.
• If risky, enable behind a feature flag.

6) Integrate (trunk-based)

• Merge early/often. Keep main always releasable.

7) Release

• Use Changesets to create semver bumps and release notes. Publish with provenance and SBOM.

8) Operate & learn

• Instrument with OpenTelemetry; use structured logging (Pino). Track DORA-ish solo metrics: lead time, deploy frequency, MTTR.
