Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00063 | $0.00276 |
| Opus 5 | $0.00032 | $0.00138 |
| Sonnet 5 | $0.00013 | $0.00055 |
| Haiku 4.5 | $0.00006 | $0.00028 |
Grade A, and why
swarmauri-add-base-mixin 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 11d 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.
What it actually says
Swarmauri Add Base Mixin
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
ComponentBasemodel 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.
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.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

swarmauri-add-base-mixin is a skill published in the GitHub repository swarmauri/swarmauri-sdk (103 stars, last pushed 29d ago), licensed Apache-2.0. It adds 63 tokens to every session and 276 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
