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 | $0.00051 | $0.00958 |
| Opus 5 | $0.00026 | $0.00479 |
| Sonnet 5 | $0.00010 | $0.00192 |
| Haiku 4.5 | $0.00005 | $0.00096 |
Grade A, and why
remove-web-platform 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 yesterday.
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 — 129 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Remove Platform Skill
This skill defines the process for completely removing all files, configurations, and dead code associated with the web platform from the codebase when restricted to mobile (Android/iOS) only.
1. Delete Web and Deployment Files
Delete the web/ directory and any web-only deployment/configurations from the
project root:
- Delete the web platform folder:
web/ - Delete the web deployment configurations (e.g.,
Dockerfile,nginx.conf).
2. Clean Up Web Dependencies
Remove web-only plugins or packages from the dependencies list in the root pubspec.yaml:
- Open
pubspec.yaml. - Delete the
flutter_web_pluginsdependency:- flutter_web_plugins: - sdk: flutter - Run melos package bootstrap:
melos bootstrap
3. Delete app_ui Web Components
Delete the web-specific design and styling components in packages/app_ui:
- Delete the web-specific exports file (e.g.,
packages/app_ui/lib/app_ui_web.dart). - Delete the web-specific widgets directory (e.g.,
packages/app_ui/lib/src/widgets/web/).
4. Clean Up Bootstrap Files
Remove web-specific initializers in lib/src/_bootstrap/ (or equivalent setup):
- Delete any
_web.dartbootstrap files. - Remove HTML conditional imports from the main bootstrap file:
-import 'package:my_app/.../_stub.dart' - if (dart.library.html) '_web.dart' - if (dart.library.io) '_native.dart' - as lib; +import 'package:my_app/.../_stub.dart' + if (dart.library.io) '_native.dart' + as lib;
5. Scan and Delete Web View Files
In features, web views typically follow a naming convention like *_view_web.dart,
while mobile views use *_view.dart. Scan the lib/ directory for any files
matching *_view_web.dart and delete them.
6. Clean Up Page and Routing References
Remove imports and references to the deleted web views inside the corresponding parent pages:
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.

remove-web-platform is a skill published in the GitHub repository anoopsg/agent_rules (2 stars, last pushed 1mo ago), licensed MIT. It adds 51 tokens to every session and 958 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.
