Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00070 | $0.00853 |
| Opus 5 | $0.00035 | $0.00426 |
| Sonnet 5 | $0.00014 | $0.00171 |
| Haiku 4.5 | $0.00007 | $0.00085 |
Grade A, and why
design-register-bootstrap 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 9d 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.
How it starts
The opening of the file, as written. The whole thing — 94 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Design Register Bootstrap
Set the design register before styling anything substantial.
This skill exists for cases where the model is about to generate UI from vague vibes, default templates, or half-remembered brand intent.
Use For
- new frontend projects without
PRODUCT.mdorDESIGN.md; - redesigns where the surface is unclear: marketing brand page vs. app/product UI;
- teams that keep getting mismatched typography, palette, density, or motion across tasks;
- sessions where the agent should create or refresh design context before implementation.
Core Rule
Classify the surface first:
brand: marketing site, landing page, portfolio, campaign, editorial page, investor page, event page;product: dashboard, admin UI, internal tool, settings, onboarding flow, forms, data-heavy app shell.
Do not treat these as interchangeable. Brand surfaces can lead with identity and emotion. Product surfaces must optimize comprehension, workflow, and control clarity.
Workflow
- Read current evidence:
- project files, CSS tokens, component library, screenshots, references, user brief;
- any existing
PRODUCT.md,DESIGN.md, brand notes, or design tokens.
- Write a compact design register:
- surface type:
brandorproduct; - audience;
- first-screen job;
- creator intent: what the person is actually trying to make possible;
- preserve-theirs: what must remain recognizably theirs;
- brand/product lane;
- anti-references: what this should explicitly not resemble;
- color strategy: restrained, committed, full palette, or drenched;
- typography direction;
- motion tolerance;
- density and radius rules.
- surface type:
- If context files are missing, create or update:
PRODUCT.mdfor audience, product lane, workflow, tone, creator intent, preserve-theirs, and anti-references;DESIGN.mdfor colors, typography, spacing, component patterns, creator intent, preserve-theirs, and do/don't rules.
- Ask one clarifying question only when either the branch between
brandandproductis genuinely unclear or creator intent is too vague to guide a real design choice. If neither blocks a real choice, move. - Use the register as a constraint system for later frontend work. Do not restyle pages in the same pass unless the task explicitly includes implementation.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

design-register-bootstrap is a skill published in the GitHub repository markoblogo/abvx-agent-skills (16 stars, last pushed today), licensed MIT. It adds 70 tokens to every session and 853 once invoked, about $0.0003 per session on Opus 5. 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 2026-08-30.
Other skills, from other repositories
screenshot-sweep
Use whenever a screenshot is captured or supplied — a bug report, a Playwright capture, a design review, a "does this look right". Read the WHOLE image, not just the thing it was sent for: sweep it against the defect checklist below, file the findings, and add them to the todo list. When a defect is later reported…
codebase-design
Shared vocabulary for designing deep modules. Use when the user wants to design or improve a module's interface, find deepening opportunities, decide where a seam goes, make code more testable or AI-navigable, or when another skill needs the deep-module vocabulary.
cli-e2e
Write, modify, or debug Docker-based Composio CLI end-to-end tests under ts/e2e-tests/cli, including binary invocation, fixture isolation, output assertions, and package manifests. Use for CLI E2E test suites only; use cli-command for CLI source implementation.
app-screenshot-debug
Drive the running termio app via AppleScript / System Events to reach a UI state (focus the window, click a sidebar project, a terminal pane, a control), capture a pixel-accurate screenshot of just that window, and read it back for visual analysis — for diagnosing layout / spacing / alignment / 'this looks ugly'…
trace
Dispatch trace subagent to investigate unknown issues — reproduces, traces, and reports root cause for fix handoff.
codex-agent
Use when you want a second-opinion review via Codex CLI, cross-verification after another agent implements changes, debugging help, or alternative implementation proposals. Requires Codex CLI to be installed and authenticated.
