What is dify-plugin-daemon CLAUDE.md?

Development instructions for Dify Plugin Daemon, a Go service that manages plugins running locally, for debugging, or on serverless platforms such as AWS Lambda.

Use them when setting up the daemon, starting its server, configuring environment variables, generating code, or running an explicitly requested package or single test.

They give contributors the project's build, run, environment, code-generation, and testing rules, including when tests should be run.

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	$0.01590	$0.01590
Opus 5.5	$0.00636	$0.00636
Sonnet 5.5	$0.00318	$0.00318

Security

Grade A, and why

dify-plugin-daemon 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.

Project Overview

Dify Plugin Daemon is a Go service that manages plugin lifecycle for the Dify platform. It supports three runtime types:

Local runtime: Runs plugins as subprocesses via STDIN/STDOUT
Debug runtime: TCP-based debugging connection for plugin development
Serverless runtime: Deploys to platforms like AWS Lambda via HTTP

Development Commands

Build and Run

# Run the daemon server
go run cmd/server/main.go

# Run tests for a specific package (only when explicitly requested)
go test ./internal/core/plugin_daemon/...

# Run a single test (only when explicitly requested)
go test -run TestSpecificName ./path/to/package

# Generate code from definitions
go run cmd/codegen/main.go

Important Testing Note

DO NOT automatically run tests unless the user explicitly requests it. Tests should only be executed when specifically asked by the user.

Environment Setup

# Copy environment template
cp .env.example .env

# Key environment variables to configure:
# - DB_HOST, DB_NAME, DB_USER, DB_PASS: Database connection
# - PYTHON_INTERPRETER_PATH: Python 3.11+ path for plugin SDK
# - S3_USE_AWS: Set to false for non-AWS S3 storage

Architecture Overview

Core Components

Plugin Daemon (internal/core/plugin_daemon/)
- Handles plugin invocation and lifecycle management
- agent_service.go: Agent strategy invocation without JSON schema validation
- tool.gen.go, model.gen.go, oauth.gen.go: Generated service interfaces
- backwards_invocation/: Handles callbacks to Dify API server
Plugin Manager (internal/core/plugin_manager/)
- Runtime Types:
  - local_runtime/: Process-based plugin execution with Python environment
  - debugging_runtime/: TCP server for plugin development/debugging
  - serverless_runtime/: Serverless deployment
- media_transport/: Handles plugin assets and storage
- Plugin installation, uninstallation, and lifecycle management

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.
