25 — Documentation and Developer Experience Checklist#

Verify that developers and operators can find accurate information, reproduce their local environment, understand API and system behavior, make changes safely, and maintain the product without relying on undocumented knowledge.

Scope: Backend / API-specific. This file is one part of the 25_Documentation_and_DeveloperExperience.md checklist. Apply the domain-wide release gate across all applicable scope files; each checklist ID remains unique.

Review details#

• Project / product:
• Release / version / environment:
• Scope and applicable jurisdictions / markets:
• Documentation audiences / supported platforms:
• Documentation and developer-tooling owners:
• Reviewer / owner:
• Review date:
• Decision: Pending / Approved / Approved with documented exceptions / Blocked

How to use#

1. Copy this shared checklist into project-specific review records; leave every checkbox in the repository unchecked.
2. Mark [x] only after verifying the item from current guides, a reproducible setup, a working code example, documentation checks, or a documented ownership decision. Track failed items and genuine N/A rationales in project-specific notes or issues using the DOC ID; do not add evidence tables to shared templates.
3. Favor reader outcomes over document count: assess whether a representative developer can find instructions, complete a task, and diagnose common failures. Adapt to the system's language, audience, deployment model, and risk.
4. Evaluate ## API Checks and ## Frontend Checks separately where applicable, recording N/A and why outside this template for products without those interfaces.
5. Recheck critical docs and developer workflows when releases, dependencies, API contracts, deployment processes, ownership, or supported platforms change. Coordinate formal compliance, security, accessibility, and test-coverage requirements with the corresponding checklists.

Project documentation#

• DOC-008 State which product, API, SDK, or documentation version each release-sensitive page describes.

• DOC-094 Provide SDK installation and usage examples pinned or clearly matched to a supported API version when SDKs exist.
• DOC-095 Publish data types, enum values, nullability, timestamps, monetary units, and encoding semantics needed for safe integrations.
• DOC-096 Include warnings and examples for destructive operations, bulk exports, irreversible actions, or large payloads.
• DOC-097 Keep OpenAPI or an equivalent contract synchronized with live service behavior and validate it before publication.
• DOC-098 Define API versioning, deprecation timelines, migration steps, and contact paths for breaking changes.
• DOC-099 Explain sandbox fixtures, test credentials, mocks, and rate-limited test procedures without requiring real customer data.
• DOC-100 Test published copy/paste examples against a controlled environment with valid dependencies and current configuration.

Release gate#

• Critical readers can discover the current getting-started, support, architectural, and operational documentation appropriate to their responsibilities.
• Setup and essential development, test, or build commands have been exercised successfully on a supported clean environment or have an approved, documented risk-based alternative.
• Public or cross-team API/interface references and associated runnable examples match the release candidate, with visible compatibility and migration guidance where relevant.
• Frontend component, accessibility, data-state, and deployment guidance is updated for affected UI features where applicable.
• Critical operational runbooks, ownership contacts, and incident escalation paths are accurate and available to authorized responders.
• Documentation errors affecting essential onboarding, safe operations, or integration are fixed, or have explicit authorized dispositions and tracked remediation.
• A named owner has reviewed documentation currency, broken links, and unresolved feedback for the exact release being approved.

Domain-specific approval rule: Block documentation/enablement sign-off when a critical setup cannot be reproduced, the documented interface contradicts deployed behavior, a destructive procedure is misleading, or essential operational steps or owners are missing without authorized mitigation. Passing this checklist does not substitute for testing, security, accessibility conformance, or legal review.

Trusted references and scope#

These sources inform practical, verifiable documentation and developer-experience review tasks. They are not universal certification standards or verbatim rules for every software project.

• Diátaxis — Documentation framework — organizing tutorials, how-to guides, reference, and explanation by reader need.
• DORA — Documentation quality — documentation clarity, findability, reliability, and developer effectiveness.
• Write the Docs — Docs as code — version control, review, automated tests, and shared documentation ownership.
• Google developer documentation style guide — clear, consistent, audience-centered technical writing.
• Google developer documentation — Code samples — formatting, introducing, and explaining runnable code samples.
• Microsoft Writing Style Guide — Code examples — task-focused, safe, tested code examples with expected results.
• Microsoft Writing Style Guide — Writing for all abilities — clear, accessible language and alternative interaction guidance.
• GitHub Docs — About README files — project purpose, getting started, support, and repository discoverability.
• GitHub Docs — Guidelines for repository contributors — documenting contribution workflows and expectations.
• GitHub Docs — About CODEOWNERS — repository ownership and review routing when used.
• OpenAPI Specification v3.2.1 — machine-readable descriptions of HTTP API operations and contracts.
• W3C WAI — Headings — accessible document heading structure and navigation.

Applicability: Documentation types and review depth depend on project size, audience, release risk, language, and support model. GitHub-specific contributor features, CODEOWNERS, shared design systems, formal OpenAPI descriptions, and public API quickstarts are conditional; choose equivalent controls where appropriate. README.md in this checklist repository remains intentionally minimal and must not be changed without a separate request.

Source review date: 2026-11-12.

Suggested testing tools#

Choose tools appropriate to the project's stack and risks; automation supports evidence but does not approve the checklist.

• Test focus: links, snippets, onboarding setup, and API documentation examples; include API and service behavior where applicable.
• Cross-stack: lychee + markdownlint-cli2.
• Python: doctest + pytest; for pytest-based suites, run python -m pytest -q.
• TypeScript: TypeDoc + Vitest; for Vitest-based suites, run npx vitest run (or npx playwright test for E2E).
• JavaScript: JSDoc + Jest; for Jest-based suites, run npx jest --ci (or npx playwright test for E2E).
• Evidence: Save tool versions, configuration, test environment, fixtures, results, and links in project-specific review records using the existing checklist IDs. Expert review remains necessary where relevant.

Suggested AI skills for verification#

These are optional agent review aids, not automated passes or release approval. Each linked repository had at least 1,000 GitHub stars when checked on 2026-11-12; counts are per repository, not per skill, and do not indicate security or correctness.

• documentation-and-adrs — Review documentation and decision-record accuracy (addyosmani/agent-skills, 116,378 repo stars).
• docs-sync-audit — Find documentation drift against code (github/awesome-copilot, 41,073 repo stars).
• doc-coauthoring — Review onboarding and instruction clarity (anthropics/skills, 193,495 repo stars).

How to check: In a project-specific copy, have the agent audit the backend / API scope and map findings to this file's existing checklist IDs, with code/configuration references, reproducible test results, failed or inapplicable cases, and uncertainties. Independently verify findings; keep shared template boxes unchecked and retain human approval requirements.

Before use: Read the skill's SKILL.md, referenced scripts, license, and requested tool permissions. Only execute vetted skills with appropriate access in a controlled environment.

Important warning: reference only#

⚠️ Reference only — not a definitive or exhaustive checklist. This template is a starting point for review, not the ultimate authority or a guarantee of project safety, quality, regulatory compliance, accessibility, security, or launch readiness.

Use project-specific judgment and independent verification. Requirements and risks evolve and differ by project, technology, and jurisdiction. Adapt the checks, consult current authoritative sources, perform relevant tests, and obtain qualified specialist review or approval when appropriate. Checking every box does not replace these steps.
