A one-time setup command for a Flutter project that records its existing design patterns in a .klamben.md context file.

Scanning Flutter and Dart files, identifying design and platform conventions, asking UX questions, and saving the findings for other commands.

It gives later design advice information about the project’s theme, fonts, platform behavior, accessibility, and localization choices.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00036	$0.01319
Opus 5	$0.00018	$0.00660
Sonnet 5	$0.00007	$0.00264
Haiku 4.5	$0.00004	$0.00132

Security

Grade A, and why

teach 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 7d 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.

The opening of the file, as written. The whole thing — 163 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/teach

First-time setup for klamben. Run once when you add klamben to a Flutter project. Gathers design context and saves it to .klamben.md so all other commands give project-tailored advice.

When to use

First time using klamben in a project
After a major rebrand or redesign
When switching target platforms

Process

Step 1: Codebase scan (automatic)

Scan the project without asking questions. Read these files and extract what you can:

pubspec.yaml — app name, Flutter/Dart SDK version, dependencies (google_fonts, flutter_localizations, intl, flutter_svg, cached_network_image, flutter_platform_widgets, cupertino_icons)
lib/ Dart files — search for:
- ThemeData — seed color, useMaterial3, textTheme, colorScheme
- ColorScheme.fromSeed — extract seed color
- GoogleFonts. — which font
- ThemeExtension — spacing tokens, custom extensions
- Platform.isIOS / Platform.isAndroid — platform branching
- .adaptive constructors — Switch.adaptive, Slider.adaptive
- CupertinoPageRoute, CupertinoButton — Cupertino usage
- Semantics, tooltip: — accessibility patterns
- AppLocalizations, flutter_localizations — i18n setup
- l10n.yaml — localization config
analysis_options.yaml — existing lint rules

Build an internal summary of what you found. Note which questions from Step 2 are already answered by the scan.

Step 2: Ask questions (one at a time)

Skip any question already answered by the codebase scan. Use multiple choice when possible.

Q1: Target platforms (skip if scan found platform branching)

Which platforms does this app target?

Android + iOS with platform-adaptive UI (Recommended)
Android + iOS with Material-only UI
Android only
iOS only

Q2: Brand personality (always ask)

Pick 2-3 words that describe this app's personality:

Professional / Playful / Minimal / Bold / Warm / Technical / Premium / Friendly
(or let the user type their own)

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.
