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 | $0.00275 | $0.06948 |
| Opus 5 | $0.00138 | $0.03474 |
| Sonnet 5 | $0.00055 | $0.01390 |
| Haiku 4.5 | $0.00028 | $0.00695 |
Grade B, and why
stream-react scanned grade B with 1 finding 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.
Recursive force deletemediumDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
Bash(mv .scaffold*), Bash(rm -rf .scaffold), Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
How it starts
The opening of the file, as written. The whole thing — 274 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Stream React (web) - scaffold + enhance + audit + migrate
Read first (every session): Read
RULES.md(React/Next.js non-negotiables) and the cross-cutting../stream/RULES.md. Where the two files state the same rule differently (e.g. Strict mode protection, Package manager), this pack'sRULES.mdwins for React work. Glob../stream/SKILL.md; if empty, install withgetstream skills stream.CLI: CLI usage (onboarding, credentials, auth, every
getstream apicall) lives in the root skill - its "Stream CLI" section in../stream/SKILL.md, with CLI safety in../stream/RULES.md. Glob../stream/SKILL.md; install silently if missing (getstream skills stream).
This skill builds, enhances, audits, and migrates Stream Chat, Video, and Feeds in React / Next.js web apps - the default pack for all web React work. It covers five tracks:
- Track A - Scaffold a new app: Steps 0-7 below. Use when the cwd is empty / new and the user said "build me a ... app".
- Track E - Enhance an existing app: see
enhance.md. Skips scaffold + theme; reuses the same SDK wiring and component blueprints. - Track F - Audit an existing integration (read-only): for "audit/review my video integration", "check my app against best practices", "is my video app production-ready?", "what am I missing before launch?". Video only: load the Integration best-practices audit section in
references/VIDEO.mdand follow its protocol - it has a Video-specific checklist + output contract. If the user asks to audit Chat or Feeds, say up front there is no dedicated best-practices checklist for those yet, then do a general docs-based review (fetch the relevant pages fromreferences/docs-map.mdand check the app against them) rather than applying the Video checklist. Skip onboarding, auth, the CLI, and all build steps - this track only reads the app and reports findings. Fix issues only if the user then asks. - Track M - Migrate / upgrade an SDK version: see
migrate.md. For "upgrade stream-chat-react to v14", "migrate to the new SDK", "bump my Stream version". Docs-driven: detect the installed version, fetch the matching release guide, apply it. Never migrate from memory. - Track S - Migrate from Sendbird: see
sendbird-migration.md. For "migrate my app from Sendbird to Stream", "replace @sendbird/uikit-react with Stream", "we're switching off Sendbird". Detects the existing Sendbird integration shape, swaps packages + init, re-implements each touchpoint (UI composition, channels, messages, events/pagination, moderation, theming) against the grounded Sendbird<->Stream mapping the file carries, then offers the separate data migration.

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.

stream-react is a skill published in the GitHub repository GetStream/agent-skills (18 stars, last pushed 3d ago), licensed Apache-2.0. It adds 275 tokens to every session and 6,948 once invoked, about $0.0014 per session on Opus 5. A static security scan graded it B with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
