Technical writing

Write accurate, task-focused documentation for eve. Treat developers and AI agents as readers: make each section easy to scan, retrieve, and act on without relying on unstated context.

Choose a workflow

• For a new page or full rewrite, read references/writing-workflow.md.
• For targeted or structural changes to existing pages, read references/editing-workflow.md.
• Before finalizing any change, read references/review-framework.md.
• For formatting and terminology, read references/style-rules.md.
• For wording, voice, or AI-pattern concerns, read references/prose-quality.md.
• For page structure, read references/content-types.md when the content type is unclear or changing.

Verify before writing

Do not rely on training data for eve behavior. Use this source hierarchy:

1. Current source, public types, and tests in packages/eve
2. Current CLI help and setup implementation
3. Existing pages under docs/
4. Merged pull requests, changelogs, and release notes
5. Research plans under research/ as proposed intent, not shipped behavior
6. Support evidence such as Slack threads or issues

Use support evidence to identify the reader's problem, not to establish product behavior. Verify commands, flags, API names, defaults, limitations, and examples against the current repository. For a docs-only change, also compare the implementation with the latest public release so the docs do not announce branch-only behavior. When docs accompany product code in the same change, state that dependency during review. If a claim cannot be verified, omit it or report the missing owner or source. Never leave [VERIFY] markers in a completed docs change.

Follow eve conventions

• Write eve lowercase, including headings and sentence starts when practical.
• Use exact public names such as defineAgent, eve dev, and eve add channel/slack.
• Distinguish the root agent, the built-in agent tool, declared subagents, and remote agents. They have different inheritance and execution semantics.
• Distinguish eve connections from Vercel Connect, the model-facing Workflow tool from authored Vercel Workflows, and durable session state from sandbox filesystem or attachment storage.
• Name diagnostic surfaces precisely: Vercel runtime logs, Agent Runs, OpenTelemetry, eve logs, and eve traces are not interchangeable.
• Treat docs/** as published documentation. Update docs/meta.json when navigation changes.
• Keep .md files framework-agnostic. Use MDX components only in .mdx files and only when nearby pages establish the convention.
• Preserve published routes and heading anchors when possible. When moving a page, update authored links and add permanent redirects for old HTML and Markdown URLs.
• Prefer TypeScript examples. Include imports and language labels, and verify examples against current exports.
• Show only supported commands and flags. Check CLI help or the command implementation before documenting them.
• Link to related pages with descriptive text. Include the critical fact locally because retrieved sections may be read without their links.
• Leave no page orphaned. Every page needs at least one descriptive inbound body link from a related hub or overview page; a meta.json sidebar entry or a routing-table cell alone is not enough. When adding a page, add the inbound link from the page that owns the topic in the same change, and keep every page reachable by following body links from getting-started.
• Do not document proposed behavior as shipped. Describe unsupported boundaries directly when they affect a user task.
• Describe current behavior only. Migration steps, removed options, and renames belong in changesets and release notes, not in docs/**.
• Document the contract, not the mechanism. Leave out internal modules, algorithms, and data structures unless the reader needs them to configure, debug, or reason about a limit.

Write for the task

• Lead each page and section with the answer or outcome. Feature pages follow the feature page shape in references/content-types.md: opening, minimal example, rules, options, then variants.
• Write prose in the reader's words, not eve's runtime vocabulary. See Plain words in references/style-rules.md.
• Address the reader as you; use imperative verbs for steps.
• Prefer active voice, present tense, concrete nouns, and consistent terms.
• Preserve the author's supported meaning, nuance, and uncertainty. Make the minimum effective edit and leave strong prose alone.
• Keep one page focused on one primary job. Add a section to an existing page when it already owns the task.
• Put the happy path before alternatives and failure modes.
• Add troubleshooting where observed failures cluster around a workflow. Use symptoms, verified causes, and concrete next checks.
• Write self-contained sections. Repeat the full noun in key statements instead of relying on ambiguous pronouns.
• Use specific limits and behavior only when the repository or an authoritative platform source supports them.

Avoid common failures

• Do not invent flags, registry entries, connectors, workarounds, or platform guarantees.
• Do not turn one product request into a new page. First decide whether the gap belongs to docs, product, or both.
• Do not duplicate broad guides when a focused section or cross-link resolves the problem.
• Do not rewrite clear prose merely to match a personal preference.
• Do not manufacture examples, opinions, reactions, or specificity to make prose sound more human.
• Do not use promotional language, rhetorical questions, filler, or claims that a task is easy, simple, or quick.
• Do not use we unless describing a deliberate Vercel or eve team action.

Finish the change

1. Re-read every changed page in full.
2. Verify each new technical claim against its source.
3. Search for contradictory statements and affected cross-links.
4. Confirm added or moved pages have an inbound body link from a related page, so no page is orphaned.
5. Run the review workflow.
6. Check changed prose against the prose-quality reference when wording changed materially.
7. Run pnpm docs:check when preparing to push, unless the user requests earlier validation.
