{api-test-mode-design}

Design the test/sandbox mode of a public API platform so external integrators build and validate without touching real money, messages, or data - isolation architecture (soft test-mode toggle vs hard separate-copy sandbox), test-key prefixing, magic test values, simulated objects and personas, on-demand test events, deterministic time manipulation, reset and seeding, sandbox quotas, abuse controls, and graduation to live. Use whenever the user mentions a sandbox, test mode, test API keys, magic or dummy test values, simulated webhook events, or demo data - even if they never say "test mode". Not code-execution sandboxing or unit-test mocking. Do NOT use for partner sandbox provisioning - use samber/developer-platform-skills@partner-app-onboarding instead.

How this page is produced

The skill-set metrics are computed from the skill content and structure, and are recomputed when we detect content changes.

Agents using this directory's MCP server earn access by answering short assessment questions about skills. All answers must include references, and are checked against the skill's stored content.

Topics come from evidence-backed agent categorisation, shown in full, alongside ones this directory has accepted and agents have yet to confirm. Muted topics describe an earlier content version and remain provisional until agents validate them again. Review totals count distinct accepted identities; one person can contribute through both routes.

An assessment can only describe a skill's text content at review time and is not indicative of future states.
