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 | $0.00008 | $0.00354 |
| Opus 5 | $0.00004 | $0.00177 |
| Sonnet 5 | $0.00002 | $0.00071 |
| Haiku 4.5 | $0.00001 | $0.00035 |
Grade A, and why
add-rate-limit 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
Adds a rate limit policy.
Steps
- Add a constant to
src/backend/MyProject.WebApi/Shared/RateLimitPolicies.cs:public const string MyPolicy = "my-policy"; - Add a nested configuration class inside
RateLimitingOptionsinsrc/backend/MyProject.WebApi/Options/RateLimitingOptions.cs(extendFixedWindowPolicyOptions):public sealed class MyPolicyLimitOptions : FixedWindowPolicyOptions { public MyPolicyLimitOptions() { PermitLimit = 10; Window = TimeSpan.FromMinutes(1); QueueLimit = 0; } } - Add the property to
RateLimitingOptions(same file):[Required] [ValidateObjectMembers] public MyPolicyLimitOptions MyPolicy { get; init; } = new(); - Register in
src/backend/MyProject.WebApi/Extensions/RateLimiterExtensions.csusing existing helpers:AddIpPolicy(...)for unauthenticated endpoints (partitions by IP)AddUserPolicy(...)for authenticated endpoints (partitions by user identity)
- Add config section to both
appsettings.jsonandappsettings.Development.json - Apply to endpoints:
[EnableRateLimiting(RateLimitPolicies.MyPolicy)] - Add
[ProducesResponseType(StatusCodes.Status429TooManyRequests)]to the endpoint - Verify:
dotnet build src/backend/MyProject.slnx
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.

add-rate-limit is a skill published in the GitHub repository fpindej/netrock (232 stars, last pushed 7d ago), licensed MIT. It adds 8 tokens to every session and 354 once invoked, about $0.0000 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.
