What it does

Backend To Frontend Handoff Docs is an agent skill from davila7/claude-code-templates. Create API handoff documentation for frontend developers. Use when backend work is complete and needs to be documented for frontend integration, or user says 'create handoff', 'document API', 'frontend handoff', or 'API documentation'.

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `README.md`).

It sits in Frontend & Design, covering Frontend development and Technical documentation. The repository describes itself as: CLI tool for configuring and monitoring Claude Code. The licence is MIT.

When your agent uses it

  • Backend work is complete and needs to be documented for frontend integration
  • User says create handoff
  • Frontend handoff
  • API documentation

Example prompts

  • “create handoff”
  • “document API”
  • “frontend handoff”
  • “/backend-to-frontend-handoff-docs”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Collect context — confirm feature name, relevant endpoints, DTOs, auth rules, and edge cases.
  2. Create/update handoff file — write the document to .claude/docs/ai//api-handoff.md. Increment the iteration suffix (-v2, -v3, …) if…
  3. Paste template — fill every section below with concrete data. Omit subsections only when truly not applicable (note why).
  4. Double-check — ensure payloads match actual API behavior, auth scopes are accurate, and enums/validation reflect backend logic.

What it can do on your machine

Read from SKILL.md and the folder at commit c0ca7da. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown, json and typescript).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Backend To Frontend Handoff Docs loads about 1.3k tokens when it runs. Until then it costs about 67 tokens; SKILL.md has 451 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~67
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Create API handoff documentation for frontend developers. Use when backend work is complete and needs to be documented for frontend integration, or user says 'create handoff', 'document API', 'frontend handoff', or 'API documentation'.

API Handoff Mode

No Chat Output: Produce the handoff document only. No discussion, no explanation—just the markdown block saved to the handoff file.

You are a backend developer completing API work. Your task is to produce a structured handoff document that gives frontend developers (or their AI) full business and technical context to build integration/UI without needing to ask backend questions.

When to use: After completing backend API work—endpoints, DTOs, validation, business logic—run this mode to generate handoff documentation.

Simple API shortcut: If the API is straightforward (CRUD, no complex business logic, obvious validation), skip the full template—just provide the endpoint, method, and example request/response JSON. Frontend can infer the rest.

Goal

Produce a copy-paste-ready handoff document with all context a frontend AI needs to build UI/integration correctly and confidently.

Inputs

  • Completed API code (endpoints, controllers, services, DTOs, validation).
  • Related business context from the task/user story.
  • Any constraints, edge cases, or gotchas discovered during implementation.

Workflow

  1. Collect context — confirm feature name, relevant endpoints, DTOs, auth rules, and edge cases.
  2. Create/update handoff file — write the document to .claude/docs/ai/<feature-name>/api-handoff.md. Increment the iteration suffix (-v2, -v3, …) if rerunning after feedback.
  3. Paste template — fill every section below with concrete data. Omit subsections only when truly not applicable (note why).
  4. Double-check — ensure payloads match actual API behavior, auth scopes are accurate, and enums/validation reflect backend logic.

Output Format

Produce a single markdown block structured as follows. Keep it dense—no fluff, no repetition.

markdown
# API Handoff: [Feature Name]

## Business Context
[2-4 sentences: What problem does this solve? Who uses it? Why does it matter? Include any domain terms the frontend needs to understand.]

## Endpoints

### [METHOD] /path/to/endpoint
- **Purpose**: [1 line: what it does]
- **Auth**: [required role/permission, or "public"]
- **Request**:
  ```json
  {
    "field": "type — description, constraints"
  }
  • Response (success):
    json
    {
  "field": "type — description"
}
  • Response (error): [HTTP codes and shapes, e.g., 422 validation, 404 not found]
  • Notes: [edge cases, rate limits, pagination, sorting, anything non-obvious]

[Repeat for each endpoint]

Data Models / DTOs

[List key models/DTOs the frontend will receive or send. Include field types, nullability, enums, and business meaning.]

typescript
// Example shape for frontend typing
interface ExampleDto {
  id: number;
  status: 'pending' | 'approved' | 'rejected';
  createdAt: string; // ISO 8601
}

Enums & Constants

[List any enums, status codes, or magic values the frontend needs to know. Include display labels if relevant.]

ValueMeaningDisplay Label
pendingAwaiting reviewPending

Validation Rules

[Summarize key validation rules the frontend should mirror for UX—required fields, min/max, formats, conditional rules.]

Business Logic & Edge Cases

  • [Bullet each non-obvious behavior, constraint, or gotcha]
  • [e.g., "User can only submit once per day", "Soft-deleted items excluded by default"]

Integration Notes

  • Recommended flow: [e.g., "Fetch list → select item → submit form → poll for status"]
  • Optimistic UI: [safe or not, why]
  • Caching: [any cache headers, invalidation triggers]
  • Real-time: [websocket events, polling intervals if applicable]

Test Scenarios

[Key scenarios frontend should handle—happy path, errors, edge cases. Use as acceptance criteria or test cases.]

  1. Happy path: [brief description]
  2. Validation error: [what triggers it, expected response]
  3. Not found: [when 404 is returned]
  4. Permission denied: [when 403 is returned]

Open Questions / TODOs

[Anything unresolved, pending PM decision, or needs frontend input. If none, omit section.]


---

## Rules
- **NO CHAT OUTPUT**—produce only the handoff markdown block, nothing else.
- Be precise: types, constraints, examples—not vague prose.
- Include real example payloads where helpful.
- Surface non-obvious behaviors—don't assume frontend will "just know."
- If backend made trade-offs or assumptions, document them.
- Keep it scannable: headers, tables, bullets, code blocks.
- No backend implementation details (no file paths, class names, internal services) unless directly relevant to integration.
- If something is incomplete or TBD, say so explicitly.

## After Generating
Write the final markdown into the handoff file only—do not echo it in chat. (If the platform requires confirmation, reference the file path instead of pasting contents.)
