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 | $0.00061 | $0.01222 |
| Opus 5.5 | $0.00024 | $0.00489 |
| Sonnet 5.5 | $0.00012 | $0.00244 |
| Haiku 4.5 | $0.00006 | $0.00122 |
Grade C, and why
find-skills scanned grade C with 2 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 1mo 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.

curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Find & Create Skills
Discover community skills and create new ones when SerpentStack's built-in skills don't cover what the user needs.
When to Use This Skill
Use this when the user asks for something outside the scope of the built-in skills:
| Built-in Skill | Covers |
|---|---|
scaffold |
Generating new API endpoints and frontend pages following project conventions |
auth |
Understanding auth, protecting routes, swapping providers |
test |
Running and interpreting pytest and vitest |
db-migrate |
Alembic migrations, schema changes, seed data |
dev-server |
Starting, monitoring, and auto-fixing the dev environment |
deploy |
Docker build, ECR push, Terraform apply to AWS |
git-workflow |
Branches, commits, PRs, rebasing |
generate-skills |
Interviewing a developer to produce project-specific skills for any codebase |
model-routing |
Delegating code generation to on-device models (Ollama) to reduce costs |
If the user needs something else — monitoring, Stripe, email, Slack, S3 file uploads, PDF generation, browser automation, etc. — search for a community skill or official docs first before building from scratch.
Step 1: Search for Existing Skills
Via web search (recommended):
Search for: "SKILL.md" <what the user needs> or site:github.com SKILL.md <topic>
Via package registries:
Many integrations have official SDKs with excellent docs:
# Python packages
uv search <topic>
# Check PyPI directly
# https://pypi.org/search/?q=<topic>
# NPM packages
npm search <topic>
Via official documentation:
For third-party services, always prefer the provider's official docs over community implementations — they're always up to date:
- Stripe: https://docs.stripe.com/api
- AWS S3: https://docs.aws.amazon.com/s3/
- SendGrid: https://docs.sendgrid.com/api-reference
- Twilio: https://www.twilio.com/docs/usage/api
Step 2: Evaluate Before Adopting
Before using any community skill or third-party integration, check:
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.

find-skills is a skill published in the GitHub repository Benja-Pauls/SerpentStack (2 stars, last pushed 6mo ago), licensed MIT. It adds 61 tokens to every session and 1,222 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
Other skills, from other repositories
feishu
Work with Feishu or Lark bots, docs, sheets, bitables, approval flows, and OpenAPI/MCP setup without hardcoding credentials.
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.
recipe-create-meet-space
Create a Google Meet meeting space and share the join link.
refocusing
Use when a long-running agent may have lost the product outcome, when context was compacted, when work has crossed a major boundary, or when a fresh path-based trace is needed before the next consequential action. Not for fresh-session orientation, waking an idle seat, or checkpoints.
printing-press-import
Bring a published CLI from the public library into the internal library so it's identical to a freshly-generated copy — module path reverted, manuscripts placed alongside, ready for /printing-press-polish or /printing-press-emboss. Use when the public library has a CLI you don't have locally, or to recover from a…

Validate Atmos projects, components, arbitrary JSON Schema inputs, EditorConfig, and GitHub Actions; use affected-file selection and native CI annotations.
