At a glance
Reference for idiomatic Python in the agent-core codebase: immutability, protocols, exception hierarchies, context managers and async patterns.
- Writing new Python modules in the agent-core repository
- SKILL.md covers Immutability, Protocol-Based Duck Typing, Custom Exception Hierarchies and Context Managers, plus 5 more sections
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
- Reviewing a change for mutable state, bare except clauses or async mistakes
What it does
This is a style reference for writing Python in the openJiuwen agent-core repository, built from patterns that recur in its code. It leans toward immutable data: frozen dataclasses with dataclasses.replace for modified copies, NamedTuple for fixed records, and typing.Final for constants that must not be reassigned.
Other sections cover typing.Protocol for structural interfaces (named for the AbilityManager and Rail base classes and plugin interfaces), a project-wide exception hierarchy rooted in AgentCoreError with a rule against bare except, class-based and function-based context managers, and async patterns such as gathering coroutines and creating background tasks. The guidance refers to that codebase's own modules, so it is of limited use elsewhere.
When your agent uses it
- Writing new Python modules in the agent-core repository
- Reviewing a change for mutable state, bare except clauses or async mistakes
- Defining a plugin interface with typing.Protocol
- Adding a custom exception under the project's error hierarchy
Example prompts
- “Convert this config class to a frozen dataclass following agent-core conventions.”
- “Review my new Rail subclass for async and exception-handling problems.”
- “Add a custom exception for sandbox failures under the existing hierarchy.”
- “Run these three API calls concurrently the way agent-core does it.”
What it can do on your machine
Read from SKILL.md and the folder at commit 8345a27. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are python and toml).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Python Patterns for agent-core loads about 2.1k tokens when it runs. Until then it costs about 24 tokens; SKILL.md has 223 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
GitHub didn't answer just now, so the file isn't shown here. It has 223 words (~2,082 tokens).
