In plain words
What is it for?
Use them to build, test, format, and lint the project, or to understand its interchangeable AI providers, messaging platforms, and memory backends.
Why use it?
They define the architecture and checks required before committing Rust changes.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md.

This is 0xNyk/oneclaw's own configuration. It tells Codex and OpenCode how to work on oneclaw itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything oneclaw configures →

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

oneclaw 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 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.

Build & Development

cargo build                    # Dev build
cargo build --release          # Release build (~3.4MB optimized binary)
cargo test                     # Run full test suite
cargo test <test_name>         # Run a single test by name
cargo clippy -- -D warnings    # Lint (must pass before commit)
cargo fmt                      # Format code
cargo fmt -- --check           # Check formatting without modifying

Validation Checklist

Before committing any Rust changes:

  1. cargo fmt
  2. cargo clippy -- -D warnings
  3. cargo test (full suite) or cargo test <name> (targeted)

Architecture

OneClaw is a single-binary Rust AI assistant (~3.4MB) with trait-based pluggable architecture. Every major subsystem is a trait with implementations swappable via config.toml.

Core Traits

Trait File Purpose
Provider src/providers/traits.rs LLM API backends (22+ providers)
Channel src/channels/traits.rs Messaging platforms (CLI, Telegram, Discord, Slack, WhatsApp, iMessage, Matrix)
Memory src/memory/traits.rs Persistence backends (SQLite with hybrid FTS5+vector search, Markdown, noop)
Tool src/tools/traits.rs Agent capabilities (shell, file_read/write, memory_store/recall/forget, browser)
Observer src/observability/traits.rs Metrics/logging (noop, log, multi)
SecurityPolicy src/security/policy.rs Sandbox, allowlists, rate limits, filesystem scoping

Adding a New Implementation

  1. Create src/<subsystem>/your_impl.rs implementing the trait
  2. Register in src/<subsystem>/mod.rs factory function
  3. Add inline #[cfg(test)] mod tests {} at the bottom of your file

Key Patterns

  • Factory functions in each module's mod.rs create trait objects from config strings
  • ReliableProvider wraps any Provider with retry + fallback chain (src/providers/reliable.rs)
  • Config is a single Config struct (src/config/schema.rs) loaded from ~/.oneclaw/config.toml

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.
