What it does
Swarmauri Add Base Mixin is an agent skill from swarmauri/swarmauri-sdk. Add or update a Swarmauri SDK base mixin in pkgs/base/swarmauribase. Use when Codex needs reusable mixin behavior tied to existing interfaces or base classes, with correct Pydantic inheritance, exports, and tests without unnecessary registry entries.
Its SKILL.md is about 320 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).
It sits in AI & LLM Engineering. It works with Pydantic and Python. The repository describes itself as: Modular Python SDK and monorepo for AI agents, LLM integrations, tools, parsers, embeddings, vector stores, and extensible application workflows. The licence is Apache-2.0.
When your agent uses it
- Codex needs reusable mixin behavior tied to existing interfaces
- With correct Pydantic inheritance
- Tests without unnecessary registry entries
Example prompts
- “/swarmauri-add-base-mixin”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Inspect sibling mixins in the target swarmauri_base family before choosing inheritance.
- Prefer the local mixin pattern: mixins usually inherit the matching core interface and BaseModel, or the narrowest existing base needed by…
- Add typed fields and methods without registering the mixin as a ComponentBase model unless the surrounding family already does so.
- Update family exports if sibling mixins are exported.
- Add focused tests for validation behavior, method behavior, and import compatibility.
What it can do on your machine
Read from SKILL.md and the folder at commit f5580ff. 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.
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
Swarmauri Add Base Mixin loads about 318 tokens when it runs. Until then it costs about 69 tokens; SKILL.md has 123 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.

Workflow
- Inspect sibling mixins in the target
swarmauri_basefamily before choosing inheritance. - Prefer the local mixin pattern: mixins usually inherit the matching core interface and
BaseModel, or the narrowest existing base needed by sibling code. - Add typed fields and methods without registering the mixin as a

Required References
Read these before changing files:
../../references/repo-patterns.md../../references/inheritance-entrypoints.md../../references/registry-rules.md
Completion Checks
- Do not update
InterfaceRegistryunless the mixin creates a new resource kind, which should be rare. - Do not add package entry points for mixins.
- Run validation for
pkgs/base.
