qiankun is a JavaScript framework for building web applications from independently developed micro frontends, allowing multiple teams to combine apps made with different frameworks. It addresses integration, isolation, deployment independence, runtime sandboxing, performance, and shared dependencies between those smaller applications. Catalogue add-ons provide workflows for using qiankun.

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 | $0.03000 | $0.03000 |
| Opus 5.5 | $0.01200 | $0.01200 |
| Sonnet 5.5 | $0.00600 | $0.00600 |
| Haiku 4.5 | $0.00300 | $0.00300 |
Grade A, and why
qiankun AGENTS.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 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.

QIANKUN PROJECT KNOWLEDGE BASE
Updated: 2026-07-06 · Commit: dcc42ae4 · Branch: next (qiankun 3.0, active dev)
Qiankun is a micro-frontend framework built on single-spa. v3 rewrites the runtime around streaming HTML-entry loading, a Proxy-membrane JS sandbox, and native ESM-sandbox execution. It is a pnpm monorepo built with Vite 8; tsc emits package declarations.
Requires Node
^22.15 || >=24,[email protected](seepackageManager). Never use npm/yarn at the root.

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.

qiankun AGENTS.md is an instructions file published in the GitHub repository umijs/qiankun (16,697 stars, last pushed 11d ago), licensed MIT. It adds 3,000 tokens to every session, about $0.0120 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.
