A coding guide for Self Serve drawer components: slide-in panels that show details without leaving the current page.

Use it when creating or changing a detail side panel, including lazy loading, parallel data requests, chart sections, responsive widths, and two-way visibility controls.

It standardizes how drawers open, load data only when needed, display charts, bind visibility, and resize across screen sizes.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00070	$0.00685
Opus 5.5	$0.00028	$0.00274
Sonnet 5.5	$0.00014	$0.00137
Haiku 4.5	$0.00007	$0.00068

Security

Grade A, and why

drawer 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 2mo 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.

Self Serve Drawer Skill

You are building or modifying a Self Serve drawer. Drawers are slide-in detail panels built on p-drawer with strict conventions for visibility, lazy data, chart integration, and responsive sizing.

When to use

A new module asks for a "drawer", "side panel", or "detail panel" that slides in.
An existing drawer needs new sections, charts, or async data.
A list-row click needs to open detail content without a route change.
A component currently uses DialogService.open for content that should slide rather than modal-pop.

If the work is a modal dialog (not a slide-in), this skill does not apply.

Workflow

Re-read docs/architecture/frontend/drawer-pattern.md (the reference linked below). The full pattern — visibility model, lazy load via toObservable(visible).pipe(skip(1), switchMap(...)), forkJoin for parallel calls, chart computed() signals, responsive width — is the source of truth.
Check what exists — read at least one current drawer in the touched module before generating new code to match the team's current shape.
Place files following the component placement table in docs/architecture/frontend/component-architecture.md (and the high-level decision tree in docs/architecture/placement.md).
Generate three files (.component.ts, .component.html, .component.scss) with the LFX license header on each. Follow the 11-section class structure from .claude/rules/component-organization.md.
Wire visibility with model<boolean>(false) — two-way [(visible)] from the parent.
Lazy-load data on open — toSignal over toObservable(this.visible).pipe(skip(1), switchMap(...)); reset drawerLoading to false on close. forkJoin for parallel calls.
Use the standard width chain — xl:w-[45%] lg:w-[55%] md:w-[70%] sm:w-[90%] w-full.
Run yarn format after writing files. Report what was changed.

Reference

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.

drawer is a skill published in the GitHub repository linuxfoundation/lfx-self-serve (16 stars, last pushed today), licensed MIT. It adds 70 tokens to every session and 685 once invoked, about $0.0003 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.
