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 | $0.00024 | $0.01325 |
| Opus 5.5 | $0.00010 | $0.00530 |
| Sonnet 5.5 | $0.00005 | $0.00265 |
| Haiku 4.5 | $0.00002 | $0.00133 |
Grade A, and why
flutter-reducing-app-size 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 1mo 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.

Core Concepts
- Debug vs. Release: Never use debug builds to measure app size. Debug builds include VM overhead and lack Ahead-Of-Time (AOT) compilation and tree-shaking.
- Upload vs. Download Size: The size of an upload package (APK, AAB, IPA) does not represent the end-user download size. App stores filter redundant native library architectures and asset densities based on the target device.
- AOT Tree-Shaking: The Dart AOT compiler automatically removes unused or unreachable code in profile and release modes.
- Size Analysis JSON: The
--analyze-sizeflag generates a*-code-size-analysis_*.jsonfile detailing the byte size of packages, libraries, classes, and functions.
Workflow: Generating Size Analysis Files
Use this workflow to generate the raw data required for size analysis.
Task Progress:
- Determine the target platform (apk, appbundle, ios, linux, macos, windows).
- Run the Flutter build command with the
--analyze-sizeflag. - Locate the generated
*-code-size-analysis_*.jsonfile in thebuild/directory.
Conditional Logic:
- If targeting Android: Run
flutter build apk --analyze-sizeorflutter build appbundle --analyze-size. - If targeting iOS: Run
flutter build ios --analyze-size. Note: This creates a.appfile useful for relative content sizing, but not for estimating final App Store download size. Use the Estimating iOS Download Size workflow for accurate iOS metrics. - If targeting Desktop: Run
flutter build [windows|macos|linux] --analyze-size.
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.

flutter-reducing-app-size is a skill published in the GitHub repository build-with-dhiraj/ai-workflow-framework-portability-kit (5 stars, last pushed 21d ago), licensed MIT. It adds 24 tokens to every session and 1,325 once invoked, about $0.0001 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 2026-09-21.
