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 | $0.00025 | $0.00246 |
| Opus 5 | $0.00013 | $0.00123 |
| Sonnet 5 | $0.00005 | $0.00049 |
| Haiku 4.5 | $0.00003 | $0.00025 |
Grade A, and why
scaffold-agent 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 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.
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
Use the scaffold-agent skill.
Agent to build: $ARGUMENTS
Clone observability-oss/dotnet-agent-starter at its newest release tag (fall back to the default branch if it has no tags), drop the .git folder, and scaffold into a new folder named after the agent. Fill only the scaffold:-marked slots — app name, system prompt, tools, corpus — and leave the observability wiring, pinned package versions, and configuration layering exactly as they are. Tools get [Description] attributes and working stubs over plausible in-memory data, including at least one honest not-found path. Run dotnet build and make it pass before reporting success, then hand off with the dotnet user-secrets commands, dotnet run, and /health-check.
If the goal wasn't given, ask what the agent should do and which 2–4 actions it needs before cloning.
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.

scaffold-agent is a command published in the GitHub repository observability-oss/progress-observability-plugin (2 stars, last pushed 7d ago), licensed MIT. It adds 25 tokens to every session and 246 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 2026-08-31.
