At a glance

SSE with useSyncExternalStore, reconnection with exponential backoff, snapshot rehydration, typed event parsing, connection status UI.

  • Works in 6 steps: SSE Store Module (lib/sse-store.ts) → Exponential Backoff (R-1, R-3) → Snapshot Rehydration (R-19) → …
  • Implementing SSE data stores
  • SKILL.md covers Overview, When to Use, Architecture and Process, plus 3 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

React Sse Patterns is an agent skill from sandgardenhq/sgai. SSE with useSyncExternalStore, reconnection with exponential backoff, snapshot rehydration, typed event parsing, connection status UI. Use when implementing SSE data stores, real-time update hooks, or connection resilience in the React SPA. Triggers on SSE, EventSource, useSyncExternalStore, real-time updates, reconnection, or live data tasks.

Its SKILL.md is about 3.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Backend & APIs, covering Realtime and WebSockets. It works with React. The repository describes itself as: Sandgarden AI Software Factory.

When your agent uses it

  • Implementing SSE data stores
  • Real-time update hooks
  • Connection resilience in the React SPA
  • UseSyncExternalStore

Example prompts

  • “/react-sse-patterns”

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. SSE Store Module (lib/sse-store.ts)
  2. Exponential Backoff (R-1, R-3)
  3. Snapshot Rehydration (R-19)
  4. Connection Status UI (R-2)
  5. Typed Event Parsing
  6. Domain Hooks (Initial Fetch + SSE)

What it can do on your machine

Read from SKILL.md and the folder at commit 9efbb7b. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

React Sse Patterns loads about 3.1k tokens when it runs. Until then it costs about 91 tokens; SKILL.md has 632 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~91
When it runs · the whole SKILL.md, loaded when a task matches
~3.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 632 words (~3,097 tokens).

“Guide for implementing Server-Sent Events (SSE) in the SGAI React SPA using React's useSyncExternalStore pattern. Covers the external store module, auto-reconnect with exponential backoff, snapshot rehydration on reconnect, typed event parsing, connection status UI, and domain hooks that combine initial…”
