interactive-state-flow

A set of rules for keeping interactive software responsive when user actions, background work, and displayed results happen at different speeds.

In plain words
What is it for?
Use it when building or fixing interactive flows such as search, selection, streaming, real-time updates, previews, and file or log views.
Why use it?
It helps prevent typing, search, navigation, or previews from feeling slow or showing results from an older request.

Token cost

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.

Security

Grade A, and why

interactive-state-flow 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.

Interactive State Flow

Purpose

Keep interactive software responsive and correct when user intent, expensive presentation, and async work progress at different speeds.

Use this skill for typing, selection, navigation, search, previews, streaming, realtime updates, file or log views, and similar flows when there is observable lag, stale-result risk, or mixed responsibility. Do not introduce extra state or scheduling boundaries into small, clear, responsive code merely because it uses async work, caching, or effects.

Runtime Contract

Keep source truth prompt

Promptly record the interaction-owned intent or input state, and commit authoritative source state through its owner, without waiting for expensive derivation or presentation. This does not require synchronous rendering or premature durable mutation; persistence remains governed by its own authority and ordering contract. Presentation state includes filtered rows, previews, rendered ranges, and pending, cached, stale, or progressive output.

Presentation may lag only when that preserves responsiveness and does not misrepresent current truth. Do not debounce the state the UI contract says is current merely to reduce downstream cost; defer its expensive consequences instead. Delayed commitment is valid when it is itself the declared product behavior.

Protect the urgent path proportionally

Name the user-visible contract before choosing a technique:

  • what must update promptly
  • what may lag, be skipped, or remain stale
  • which context makes a result obsolete
  • which boundary decides whether a result may commit

Classify follow-up work by responsibility, urgency, cost, visibility, and freshness risk. Then use the simplest mechanism that satisfies the user-visible contract.

Do not start from a preferred mechanism such as debounce, memoization, a transition, or a worker. Moving work off-thread or into another process is justified only when it protects the interaction path and the boundary has clear input, output, ownership, ordering, cancellation, and failure behavior. Account for transfer and coordination cost. Background work returns candidates; it must not bypass the accepting owner to mutate current UI or presentation.

Changes

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.

interactive-state-flow is a skill published in the GitHub repository perhapsspy/project-legibility (5 stars, last pushed 5d ago), licensed MIT. It adds 65 tokens to every session and 1,170 once invoked, about $0.0003 per session on Opus 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 2026-08-31.
