DeepChat is an open-source desktop client for AI agents that keeps user data local first and connects agents with services such as MCP, Skills, ACP, and messaging apps. It is for people who want to use and control AI assistants from a desktop application. The catalogue add-ons extend DeepChat’s agent workflows.

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 | $0.00481 | $0.00481 |
| Opus 5.5 | $0.00192 | $0.00192 |
| Sonnet 5.5 | $0.00096 | $0.00096 |
| Haiku 4.5 | $0.00048 | $0.00048 |
Grade A, and why
deepchat 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.
What it actually says
Repository Guidelines
- Prefer the smallest correct change; add no abstraction or dependency without a real need.
- Preserve unrelated worktree changes; avoid destructive Git unless explicitly requested.
- Use pnpm only; require Node >=20.19 and pnpm >=10.11.
- Core code:
src/main,src/preload,src/renderer,src/shared; stack: Electron/Vue 3/TS. - Tests: use Vitest in
test/main, Vitest with Vue Test Utils intest/renderer, and Playwright intest/e2e; run the smallest relevant suite. - Default to implementation-first development: inspect and design, complete the planned code change, then decide what new verification is needed. Do not default to TDD unless explicitly requested or a minimal executable reproduction is required to understand a complex failure.
- Existing checks may run at any time. Treat new tests as regression protection, not implementation scaffolding; remove temporary probes and tests before handoff.
- Commit only the smallest durable tests for user-visible behavior, documented contracts, persistence or migration, lifecycle or concurrency, recovery, security boundaries, or proven regressions. Prefer no new test to implementation-coupled coverage.
- Keep native capabilities behind typed preload/IPC boundaries with context isolation enabled.
- Keep executable previews on a separate origin with web security enabled; never give app-origin
srcdocboth scripts and same-origin access. Validate native IPC senders before dispatch. - Use vue-i18n for user copy; prefer existing shadcn-vue primitives and VueUse utilities.
- Follow Oxfmt: single quotes, no semicolons, 100 columns.
- Before editing, inspect ownership, callers, tests, and nearby patterns; fix the root cause.
- Before handoff run format, i18n, lint, typecheck, and relevant test suites.
- Keep provider and ACP registry refreshes produced by normal builds.
- Use Conventional Commits (
type(scope): subject, <=50 chars); never add AI co-authors. - Target routine PRs to
dev; only release branches targetmain. - Assess scope first; use SDD only for large features or complex changes, never small local work.
- For UI changes, include concise BEFORE/AFTER ASCII layouts in the PR.
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.
