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

wechat-mcp AGENTS.md scanned grade A with 1 finding 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 4d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Commits should use present-tense imperatives (`add`, `refactor`, `fix`) and stay under ~72 characters, mirroring history (`add text message sending function...`). Describe rationale and notable impacts in the body. Pull

Repository Guidelines

Project Structure & Module Organization

Source lives at the repository root with main.go, server.go, routes.go, and tool_handlers.go orchestrating the HTTP + MCP bridge. Domain logic is under repository/, grouped by feature (chatroom, contact, message, tables). Transport helpers and generated protobuf code stay in wcferry/. Shared utilities are in pkg/ (SQLite setup, random IDs, file helpers). Keep new modules within this layout; add feature-specific packages beneath repository/ and isolate cross-cutting helpers inside pkg/.

Build, Test, and Development Commands

go mod tidy syncs module dependencies before compiling. go build ./... produces a full build and validates package wiring. Run go run main.go --sdkLibrary <path> --storageDir <data> --port 10888 for local development. Use go test ./... to execute all unit tests. go fmt ./... must run before committing to apply canonical formatting.

Coding Style & Naming Conventions

Follow gofmt output (tabs for indentation, newline at EOF). Use descriptive package-level names (repository/message, pkg/sqlite3); keep exported symbols PascalCase and internal helpers camelCase. Log structured events through logrus or zap and prefer context-driven error wrapping. Filenames should remain lowercase with underscores only when mirroring external specs.

Testing Guidelines

Author _test.go files beside the code they exercise using Go's testing package; table-driven tests are encouraged for handler and repository layers. Aim to cover new repository queries and message flows, and document edge cases using subtests. Execute go test ./... before pushing and attach failure output to PRs when troubleshooting.

Commit & Pull Request Guidelines

Commits should use present-tense imperatives (add, refactor, fix) and stay under ~72 characters, mirroring history (add text message sending function...). Describe rationale and notable impacts in the body. Pull requests need: concise summary, linked issues (e.g. Fixes #123), manual test notes (go run, go test), and screenshots or curl transcripts for API changes. Request review once CI (if configured) is green.

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.
