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 | $0.00041 | $0.00700 |
| Opus 5 | $0.00020 | $0.00350 |
| Sonnet 5 | $0.00008 | $0.00140 |
| Haiku 4.5 | $0.00004 | $0.00070 |
Grade A, and why
mbedtls-integration 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 10d 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.

mbedTLS Integration
Overview
Use this skill to integrate mbedTLS on embedded targets by proving entropy/RNG, time, certificate storage, transport I/O, and memory configuration before debugging application protocols. TLS failures often come from platform hooks rather than cryptography logic.
When To Use
Use this skill when:
- The user wants TLS, HTTPS, MQTT over TLS, DTLS, X.509, crypto, or secure boot-related primitives using mbedTLS.
- The issue involves handshake failure, certificate validation, entropy source, RNG, memory allocation, time validity, or socket callbacks.
- The target is resource-constrained or has hardware crypto/TRNG.
Do not use this skill for generic networking before TCP/IP works. Use lwip-integration first when connectivity is unproven. For lightweight ECC-only operations, use micro-ecc-integration or tinycrypt-integration.
First Questions
Ask for:
- mbedTLS version, target MCU/RTOS, compiler, and network stack.
- Use case: TLS client, TLS server, DTLS, crypto only, MQTT TLS, HTTPS, or certificate parsing.
mbedtls_config.h, enabled features, heap/static allocation policy, and hardware crypto use.- Entropy/RNG source and time source.
- Certificate chain model, CA storage, SNI/hostname verification, and current error code.
Integration Checklist
-
Prove entropy and RNG. TLS requires a real entropy source. Do not ship deterministic test entropy.
-
Configure time. Certificate validation needs valid time or an explicit product policy for time-less validation.
-
Bound memory. Configure record size, heap, I/O buffers, certificate features, and algorithms for MCU limits.
-
Connect transport callbacks. Network send/recv callbacks must handle non-blocking, timeout, and partial I/O correctly.
-
Validate certificates. Use CA chain, hostname/SNI, and expected verification policy. Do not disable verification silently.
-
Decode error codes. Convert negative mbedTLS errors to readable names before guessing.
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.

mbedtls-integration is a skill published in the GitHub repository easyzoom/aix-skills (31 stars, last pushed 1mo ago), licensed MIT. It adds 41 tokens to every session and 700 once invoked, about $0.0002 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.
