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.
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.

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 | $0.00052 | $0.00994 |
| Opus 5 | $0.00026 | $0.00497 |
| Sonnet 5 | $0.00010 | $0.00199 |
| Haiku 4.5 | $0.00005 | $0.00099 |
Grade A, and why
add-provider 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 6d 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 — 122 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Add Provider
Goal
Generate DeepChat provider integration changes against the current provider architecture. Keep
provider display data in PublicProviderConf, map runtime behavior to known transports, and use a
special provider implementation only when the API behavior requires one.
Required Inputs
Collect or derive these before editing source:
- Provider ID in kebab case.
- Display name.
- API type or known transport family.
- Default base URL.
- Auth type: API key, no auth, OAuth, profile credentials, or provider-specific credential.
- Model metadata source: built-in config, provider-db, config-db, live model fetch, or custom only.
- Test model ID and check strategy.
- Official website, API key URL, docs URL, model list URL.
- Request quirks: headers, endpoint suffixes, route rewrites, streaming shape, tool-call support, reasoning support, image/audio/embedding endpoints, or proxy requirements.
Supported Paths
OpenAI-Compatible API
Use this when the provider supports OpenAI Chat Completions or Responses-compatible HTTP APIs.
Typical files:
src/main/provider/defaults.tssrc/main/provider/providerId.tssrc/main/provider/providerRegistry.tssrc/shared/providerDbCatalog.tswhen models come from the public provider databasetest/main/**provider registry or creation tests
Existing Native Transport
Use this when the provider maps to an existing DeepChat transport such as Anthropic, Gemini, Vertex, Azure, Bedrock, Ollama, or ACP.
Typical files:
src/main/provider/defaults.tssrc/main/provider/providerRegistry.ts- Settings components only when the existing generic form lacks required fields
- Focused tests for provider creation and connection checks
Special Provider
Use this when auth, request shape, streaming, discovery, or error handling differs from existing transports.
Typical files:
src/main/provider/providers/<providerName>Provider.tssrc/main/provider/<providerName>Adapter.tssrc/main/provider/managers/providerInstanceManager.tssrc/shared/contracts/routes/*andsrc/renderer/api/*Client.tsfor interactive authsrc/renderer/settings/components/*for provider-specific settings UI- Main and renderer tests covering the new behavior
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.

add-provider is a skill published in the GitHub repository ThinkInAIXYZ/deepchat (6,309 stars, last pushed today), licensed Apache-2.0. It adds 52 tokens to every session and 994 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 2026-08-30.
Other skills, from other repositories
sync-upstream
Sync the Switchboard client with a newer official LibreChat server version — a stable release, a release candidate, or a PARTIAL sync up to an untagged upstream commit (e.g. current dev HEAD). If the client is ALREADY at the target commit, runs an AUDIT of the last synced delta to catch anything that was missed.…
audit-deps
Audit open dependabot PRs in this repo. Spawns one investigator per PR (each with a codebase-walk sub-agent), produces a comparison table with per-PR risk + recommendation, and proposes a merge order that minimizes rebase churn. Audit-only — stops at recommendations; user authorizes execution. Use when dependabot has…
release-highlights
Add a hand-written Highlights section to a GitHub release whose notes were auto-generated, summarizing the release's PRs in user-facing language above the generated changelog. Reads every PR in the range, drafts the section in the repo's house style, asks about ambiguous wording, and writes only after approval. Use…
update-web-assets
Update the third-party JavaScript vendored into the app for the artifact, diagram, and math WebViews (KaTeX, mermaid, marked, highlight.js, Tailwind, Babel, React). Checks what is outdated, reads each pin's rationale before proposing a bump, re-downloads from the official source, verifies the lock, and runs the gates.…
