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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00132 | $0.01795 |
| Opus 5.5 | $0.00053 | $0.00718 |
| Sonnet 5.5 | $0.00026 | $0.00359 |
| Haiku 4.5 | $0.00013 | $0.00179 |
Grade A, and why
build-feature 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 24d 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 — 148 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Build Feature
Orchestrate new feature work in this Svelte 5 + Hono monorepo on Cloudflare. The app has two deployed layers — apps/api (Hono worker, Cloudflare Workers) and apps/web (SvelteKit SPA, Cloudflare Pages) — plus shared packages/ui. Most features touch more than one layer; the value of this skill is coordinating them in the right order.
Step 1: Classify the feature
| Type | Layers affected |
|---|---|
| UI-only | apps/web only — new page, component, or visual change |
| Backend-only | apps/api only — new endpoint, DB change, middleware |
| Full-stack | Both apps, possibly packages/ui |
Ask the user if it isn't obvious. Knowing the scope determines which layers to read before proposing any code.
Step 2: Inspect before coding
Read the relevant existing files first. This prevents duplicate logic, wrong conventions, and mismatched types.
| What you're adding | Read first |
|---|---|
| New API route | apps/api/src/routes/index.ts, an existing route file (e.g. routes/access.ts) |
| New DB table | apps/api/src/db/schema.ts, apps/api/migrations/ |
| New web page | apps/web/src/routes/ directory listing, apps/web/src/routes/+layout.ts |
| New form | apps/web/src/lib/forms/ for existing schemas; a page that already uses superforms |
| New shared component | packages/ui/src/components/ui/, packages/ui/src/index.ts |
| Auth or subscription gating | apps/api/src/middleware/authorization.ts, apps/api/src/routes/index.ts |
If you haven't oriented to the repo yet, run /project-orientation first.
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.

build-feature is a skill published in the GitHub repository pinebasedev/svelteflare (50 stars, last pushed 25d ago), licensed MIT. It adds 132 tokens to every session and 1,795 once invoked, about $0.0005 per session on Opus 5.5. 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.
