handoff

handoff is a command for Codex from alwkala/tidyfactor-design. It costs 0 tokens per session (518 once invoked), scanned A, original, MIT.

A developer handoff document generator for turning an approved design into implementation instructions and design-system references.

In plain words
What is it for?
Use it to create token maps, component state matrices, layout specifications, and motion guidelines for production work.
Why use it?
It gives developers precise rules for colors, typography, spacing, layouts, component states, and motion instead of relying on visual guesswork.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

handoff scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Command: handoff — Developer Handoff Spec Generation

Runtime entry point for generating clean, developer-ready design system specifications, token maps, component state matrices, and implementation guidelines. Part of the Delivery & Handoff lifecycle phase.

When to use

  • After prototype approval, when handing off to engineering/developers
  • When documenting design system tokens for production implementation
  • When building a component library documentation site

Handoff Package Specification

The handoff command extracts and formats technical documentation into docs/handoff/:

docs/handoff/
├── 01-token-map.md          ← Exact CSS variables, HSL values, typography scale, spacing grid
├── 02-component-matrix.md   ← Full inventory of components with all 8 interactive states
├── 03-layout-specs.md       ← Spacing rules, grid containers, breakpoint behaviors
└── 04-motion-handbook.md    ← Easings, timing curves, reduced motion fallbacks

Generated Outputs

1. Token Map (01-token-map.md)

Export clean tables tracing brand.json v2 tokens to CSS variable implementations:

  • Color swatches with hex, HSL, and light/dark role mappings
  • Font family declarations, weights, line-height ratios, letter-spacing
  • Spacing scale values in rem and px
  • Elevation levels & shadow specs (including color-mix() focus rings)

2. Component Matrix (02-component-matrix.md)

For each shared component in design-system/components.css:

  • HTML markup snippet
  • Interactive state inventory: Default, Hover, Active, Focus-Visible, Disabled, Loading, Error, Success
  • Accessibility requirements (ARIA roles, minimum 44px touch targets)

3. Layout & Grid Specs (03-layout-specs.md)

  • Container max-widths (sm, md, lg, xl, 2xl)
  • Section padding discipline
  • RTL mirroring guidelines for bidirectional UI

4. Motion Handbook (04-motion-handbook.md)

  • Cubic-bezier curves and duration values
  • Reduced-motion fallback rules (prefers-reduced-motion: reduce)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

handoff is a command published in the GitHub repository alwkala/tidyfactor-design (5 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 518 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
