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 | $0.00292 |
| Opus 5 | $0.00012 | $0.00146 |
| Sonnet 5 | $0.00005 | $0.00058 |
| Haiku 4.5 | $0.00002 | $0.00029 |
Grade A, and why
build-afm 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 6d 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
Build AFM
Run commands from the maclocal-api repository root.
SwiftPM
Never invoke raw swift build or swift test. Always use:
Scripts/swiftpm-reliable.sh build -c release --product afm
Scripts/swiftpm-reliable.sh test -c release
The wrapper selects the known-good Xcode 27 SwiftPM driver, repairs stale
explicit-module state, resolves AFMKit's committed default.metallib, and
stages mlx.metallib for XCTest. Do not work around metallib failures with
one-off environment values.
Normal builds consume the immutable AFMKit revision and exact AFM-compatible
MLX tags. They do not compile or mutate vendor/mlx-swift-lm. Use
Scripts/check-afmkit-consumer-boundary.sh after dependency or packaging
changes. The legacy patch stack requires an explicit maintenance opt-in.
The comprehensive assertion harness must continue to delegate its Swift tests
to this wrapper. Local copied XCTest binaries also have a source-checkout
fallback in MLXMetalLibrary; packaged binaries must carry their resource
bundle or loose default.metallib beside the executable.
Performance
Use Release binaries for inference benchmarks. Never report Debug throughput.
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.

build-afm is a skill published in the GitHub repository scouzi1966/maclocal-api (337 stars, last pushed yesterday), licensed MIT. It adds 23 tokens to every session and 292 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 2026-08-30.
