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 | $0.00000 | $0.00189 |
| Opus 5.5 | $0.00000 | $0.00076 |
| Sonnet 5.5 | $0.00000 | $0.00038 |
| Haiku 4.5 | $0.00000 | $0.00019 |
Grade A, and why
lambda-function 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 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.
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
aws.lambda.function (Lambda)
Event-driven compute that scales to zero — essentially $0 for low-traffic background jobs. Config knobs: memoryMB, timeoutSec, reservedConcurrency.
When to use
- Invoked by events: SQS, S3, EventBridge, or direct SDK call.
Sizing & ceilings
memoryMBalso scales CPU proportionally; 256 MB is a safe default.timeoutSecmax 900. For jobs >15 min, use ECS tasks instead.reservedConcurrency: -1uses the account pool; set a positive value to cap parallelism and prevent runaway scaling.
Cost
- First 1M requests/mo free; essentially $0 for low-traffic background jobs.
Edge kinds
- Edge kind: network from trigger (sqs/s3) → lambda; iam from lambda → downstream resources.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

lambda-function is a skill published in the GitHub repository AlexK020908/infra-designer (2 stars, last pushed 4mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 189 tokens. 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.
