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 | $0.00428 | $0.00428 |
| Opus 5.5 | $0.00171 | $0.00171 |
| Sonnet 5.5 | $0.00086 | $0.00086 |
| Haiku 4.5 | $0.00043 | $0.00043 |
Grade A, and why
flutter-slipstream CLAUDE.md 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 2d 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.
What it actually says
flutter-slipstream
- an agentic tooling plugin to make coding agents more effective for Dart and Flutter projects
- docs table of contents at @docs/toc.md; open individual docs as needed
- user facing docs at
README.md
Feature: Flutter UI agent
inspectorMCP server for launching, inspecting, and interacting with a running Flutter app- take screenshots, inspect the widget tree, evaluate arbitrary Dart expressions, and observe runtime errors with widget IDs
- implementation reference at
docs/inspector_mcp.md - 'slipstream-inspector' skill at
skills/slipstream-inspector/SKILL.mdused to help agents trigger on 'flutter run' and document workflows and gotchas - has an optional in-process companion package, slipstream_agent;
docs/slipstream_agent.md
Feature: Package API retrieval
packagesMCP server returns package APIs as token efficient stubs- call
package_summaryto orient on a package andlibrary_stubandclass_stubfor details - related 'slipstream-packages' skill at
skills/slipstream-packages/SKILL.md - implementation reference at
docs/packages_mcp.md
Feature: Package safety skill
add-packageskill atskills/add-package/SKILL.md- fires when an agent is about to add a Dart or Flutter package dependency
- prevents adding a dependency on discontinued packages
- prevents adding a dependency on outdated versions (older major versions)

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.
