What is BrainCue CLAUDE.md?

A guide for BrainCue, a local-first desktop assistant for live conversations. It describes an Electron, React, and TypeScript app that transcribes with consent, shows relevant cues in an overlay, archives conversations, and keeps reviewed long-term memory on the user's computer.

Developing BrainCue's conversation, meeting, interview, practice, profile, memory, retrieval, and on-screen cue features. It helps agents preserve the app's local-data and consent expectations.

It gives coding agents the product context needed to change shared features without assuming the app is only for interviews. It also explains profile handling and that only retrieved context and the current question are sent to OpenAI with the user's own key.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01819	$0.01819
Opus 5.5	$0.00728	$0.00728
Sonnet 5.5	$0.00364	$0.00364

Security

Grade A, and why

BrainCue CLAUDE.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 2mo 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.

What this is

BrainCue — a local-first desktop AI companion for live conversations (Electron + React + TypeScript). It transcribes what it hears in real time (with consent), decides when it can help, and streams grounded cues into a floating, screen-share-invisible overlay ("Cue Card"). It archives each conversation so the next one starts where the last ended, and holds reviewed long-term memory per profile. Data stays on the user's machine; only retrieved context + the current question go to OpenAI (BYO key).

Interviews are one activity, not the product. Interview Copilot and Practice are still fully shipped, but meetings and solo sessions are the daily cases — when you touch a shared path (prompts, retrieval, session defaults), check that it doesn't assume an interview. See docs/00-VISION.md and docs/16-CONTINUITY.md.

One profile at a time. The dashboard is scoped by AppSettings.activeProfileId, chosen in the sidebar switcher and resolved in main (shared/activeProfile.ts) so every window agrees. Profile-scoped surfaces read it — never add another profile <Select> to a page. See docs/19-ACTIVE-PROFILE.md.

The user picks an activity, never a mode. shared/activities.ts is the one catalog: what a call IS (meeting/project/job/subject/personal/game/solo/custom), what a Space is a saved instance of, and which SessionMode the engine derives from it. There used to be two lists answering the same question and they could disagree. Never add a mode picker back to a start surface; add an activity. See docs/18-ACTIVITIES.md.

A Space is where a conversation is kept. archiveSession and extractMemoryCandidates both return 0 when sessions.packId is null — no Space, no summary, no memory. The start modal offers only the Spaces of the chosen activity (spacesFor) and says what will survive the session before it starts; the save prompt offers the choice once more and files the session before either half runs. Exactly one activity refuses to start without one (ActivityConfig.needsSpace, job). See docs/16-CONTINUITY.md §15.

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.
