DataFlow-WebUI CLAUDE.md

Project instructions for DataFlow WebUI, a local-first tool that developers run on their own machines. They define permitted web interface changes and cover areas such as agent chat, prompts, and JSON Schema management.

In plain words
What is it for?
Use them when changing the DataFlow WebUI’s frontend, agent chat, prompt templates, schemas, endpoints, or local data handling.
Why use it?
They clarify that the project does not need accounts or multi-user access and explain which improvements are allowed, reducing unnecessary authentication or access-control work.

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.

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

DataFlow-WebUI 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 3d 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.

How it starts

The opening of the file, as written. The whole thing — 50 lines — stays where its author put it; the contents beside it link to each section on GitHub.

DataFlow WebUI — Project Rules

Deployment assumption: this project is a single-user, local-first tool. Each developer/user runs both backend and frontend on their own machine. There is no authentication, no registration, no multi-tenant concern. Do NOT add login pages, JWT/session infrastructure, or per-user ACL.

WebUI Change Policy

The previous strict allow-list (only operator-rendering fixes / existing-endpoint patches) has been relaxed. New routes, new sidebar items, new backend endpoints, and new services are all permitted when they serve the goal of "completing DataFlow-WebUI as a usable local tool".

Encouraged work areas

  1. Agent chat experience — tool-call progress indicators, session persistence, multi-session switching, reconnect logic, robust error surfacing.
  2. Prompt management — both read-only browsing of the built-in PROMPT_REGISTRY AND first-class support for user-defined prompt templates (file-based persistence under backend/data/prompts/, CRUD endpoints, editor UI, reference from operator config).
  3. JSON Schema management — container-based service injection, schema validation (ajv), monaco/codemirror editor, deep integration with operator parameter panels so saved schemas can be chosen for structured LLM outputs.
  4. Operator rendering — still a priority: new/fixed node components in components/manage/mainFlow/nodes/, parameter editors, correct display of operators that already exist in OPERATOR_REGISTRY.
  5. Repo hygiene — consolidating/deleting duplicate markdown, removing stray * copy skill directories, fixing obvious code smells (same-name route handlers, hard-coded URLs, services bypassing the DI container).

Still prohibited

  • Authentication / registration / multi-user features. Single-user local tool only.
  • External telemetry / analytics uploads. No outbound reporting.
  • Breaking changes to OPERATOR_REGISTRY / PROMPT_REGISTRY semantics — always extend, never redefine, so upstream DataFlow stays compatible.

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.
