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 | $0.00056 | $0.01100 |
| Opus 5 | $0.00028 | $0.00550 |
| Sonnet 5 | $0.00011 | $0.00220 |
| Haiku 4.5 | $0.00006 | $0.00110 |
Grade A, and why
agent-skills-form 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 12d 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 — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Form
End-to-end form recipe. Markup and control rules in references/forms.md. Load agent-skills-conventions for errors, components, and hooks-state when wiring submit.
1. Decide — form library or not
| Situation | Approach |
|---|---|
| 2+ fields, validation rules, or submit state | RHF + zod — follow this skill |
| Single uncontrolled input (search, inline rename) | Plain state or a form action — no form library |
Inspect the repo: reuse an existing form pattern, schema location, and submit hook before inventing a parallel one.
2. Schema first — before markup
- Export a zod schema colocated with the feature (
lib/or next to the form component). - Derive the form type:
type CheckoutFormValues = z.infer<typeof checkoutSchema>. - List validation failures (field-level, from zod) and submit failures (server/network) separately.
- Submit failures use SCREAMING_SNAKE
ErrorKeyliterals — add them to the feature'sconstants/error-keys.tsbefore wiring submit (agent-skills-conventions:errorsrule).
Present the schema, field list, and error keys — confirm before building UI.
3. Choose controls
Pick from the control chooser in references/forms.md. Reuse shadcn/ui primitives from the project's UI layer — never raw div + space-y-* form markup.
| Need | Control |
|---|---|
| Simple text | Input |
| Dropdown | Select |
| Searchable dropdown | Combobox |
| Boolean in settings | Switch |
| Boolean in a form | Checkbox |
| Single choice, few options | RadioGroup |
| Toggle 2–5 options | ToggleGroup |
| Multi-line | Textarea |
| OTP | InputOTP |
Buttons inside inputs: InputGroup + InputGroupAddon. Related checkboxes/radios: FieldSet + FieldLegend.
4. Markup — FieldGroup / Field
'use client'on the form component leaf only.- Wrap fields in
FieldGroup→Field→FieldLabel+ control + optionalFieldDescription. - Invalid/disabled:
data-invalid/data-disabledonFieldandaria-invalid/disabledon the control. - Connect RHF:
registerorController/FormField— match what the repo already uses. - Submit errors: render from
errorKeyat display time — never hardcoded strings.
What ships with it
1 file 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.

agent-skills-form is a skill published in the GitHub repository MohammadShehadeh/agent-skills (2 stars, last pushed 28d ago), licensed MIT. It adds 56 tokens to every session and 1,100 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 2026-08-31.
