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.

SkillSpector: 30 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00112 | $0.09701 |
| Opus 5.5 | $0.00045 | $0.03880 |
| Sonnet 5.5 | $0.00022 | $0.01940 |
| Haiku 4.5 | $0.00011 | $0.00970 |
Grade A, and why
stream-flutter 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.

Stream Flutter - skill router + execution flow
Rules: Read RULES.md once per session - every non-negotiable rule is stated there, nowhere else.
This file is the single entrypoint: intent classification, local project detection, and module pointers for Stream work in Flutter apps.
Step 0: Intent classifier (mandatory first - never skip)
Before any tool call, decide the track from the user's input alone - no probes first.

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.
- 1mo ago First seen · 438 lines · 112 tokens per session scan A c24954afe8e3
stream-flutter is a skill published in the GitHub repository GetStream/agent-skills (20 stars, last pushed 2d ago), licensed Apache-2.0. It adds 112 tokens to every session and 9,701 once invoked, about $0.0004 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.
