forms-builder

A coding-agent workflow for building forms with several steps, complex data collection, or editable records in side panels. It uses shared rules for validation and organizes form sections and fields into separate modules.

In plain words
What is it for?
Use it for multi-step forms, detailed intake flows, side-panel create/edit forms, and other forms that need more structure than a single simple form.
Why use it?
It helps avoid rebuilding form structure and validation rules differently for each complex form. It also keeps large forms easier to change as they grow.

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.

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

forms-builder 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 yesterday.

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.

Apply the preloaded factory-forms-builder skill to the delegated task. The canonical skill is the complete workflow and source of truth.

Changes

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.

forms-builder is an agent published in the GitHub repository nonlinear-xyz/factory-kit (9 stars, last pushed 28d ago), licensed MIT. It adds 144 tokens to every session and 207 once invoked, about $0.0007 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 2026-08-31.
