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.

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 | $0.00072 | $0.02123 |
| Opus 5 | $0.00036 | $0.01061 |
| Sonnet 5 | $0.00014 | $0.00425 |
| Haiku 4.5 | $0.00007 | $0.00212 |
Grade A, and why
nika-migration 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 2d 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.

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.

nika-migration is a skill published in the GitHub repository supernovae-st/nika (75 stars, last pushed today), licensed AGPL-3.0. It adds 72 tokens to every session and 2,123 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other skills, from other repositories
rust-crate-ci
Load before editing any Rust crate in this repo (currently runners/swarm-sandbox-runner). Covers the mandatory local validation gate, common rustfmt/clippy pitfalls, and Windows-specific Rust correctness patterns that CI enforces but are hard to catch locally without a Windows toolchain.
static-rust
Use for Soma built-in Rust actions, scaffold intent collection, MCP elicitation flows, and CLI/REST action reference.
rust
Rust development environment. Use when the project needs this capability or the user / team manifest asks for it. Use for specialized rust work when listed in TEAM.yaml or explicitly requested.
cw-gates
Use before claiming any Codewhale change is done, green, or ready to land: the focused-to-broad verification ladder, the budget checks CI enforces, and the rules for what counts as a passing test.
gws-modelarmor
Google Model Armor: Filter user-generated content for safety.
interview
Ask one useful structured question at a time only when material product/implementation choices are genuinely missing; remember answers and produce a brief/spec. Discoverable facts should be investigated instead of asked.
