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 | $0.00023 | $0.00317 |
| Opus 5 | $0.00012 | $0.00159 |
| Sonnet 5 | $0.00005 | $0.00063 |
| Haiku 4.5 | $0.00002 | $0.00032 |
Grade A, and why
security-and-hardening 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 8d 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
security-and-hardening
When To Use
- Handling user input, authentication, authorization, secrets, storage, payments, external services, or file/network access.
- Reviewing changes that cross a trust boundary.
- Preparing production-facing code.
Workflow
- Identify assets, actors, trust boundaries, and data flow.
- Validate and normalize input at boundaries.
- Check authentication and authorization separately.
- Ensure secrets are not logged, committed, exposed to clients, or embedded in code.
- Check injection, XSS, CSRF, SSRF, path traversal, insecure deserialization, and dependency risk when relevant.
- Prefer deny-by-default and least privilege.
- Add tests or checks for critical failure paths.
Anti-Rationalization
| Excuse | Rebuttal |
|---|---|
| "Only trusted users call this." | Trust boundaries change and credentials leak. |
| "Validation happens elsewhere." | Boundary code should verify the assumption or make it explicit. |
| "This secret is just for local testing." | Secrets in code tend to spread. Do not commit them. |
Verification
- Trust boundaries and sensitive data are identified.
- Critical inputs and permissions are checked.
- Security-relevant behavior has tests or documented manual checks.
Exit Criteria
- The change does not introduce an avoidable security regression.
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.

security-and-hardening is a skill published in the GitHub repository Plazmodium/odin-workflow (0 stars, last pushed 3mo ago), licensed MIT. It adds 23 tokens to every session and 317 once invoked, about $0.0001 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 2026-09-01.
Other skills, from other repositories
b123d-modeling
Use this skill when asked to model, build, or modify a 3D part or assembly with build123d — from a text description, a technical drawing (image or PDF), dimensions in a spec, or an existing STEP/STL file.
b123d-edit
Use this skill when the task is to change an existing build123d model or script: "make this bracket 5 mm taller", "move the holes inward", "add a counterbore", "remove this rib", "make it fit this mating part", or "repair the code so the intended edit remains parametric".

Use when working with MLflow traces: debugging via MCP tools, analyzing performance, logging feedback, writing custom scorers/evaluations, or cleaning up trace data.
video-explainer
Teaches Claude how to use the 15 video explainer tools to create explainer videos from research content. Activates when working with video synthesis, explainer creation, or the video-explainer MCP server.
