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 | $0.00000 | $0.00148 |
| Opus 5 | $0.00000 | $0.00074 |
| Sonnet 5 | $0.00000 | $0.00030 |
| Haiku 4.5 | $0.00000 | $0.00015 |
Grade A, and why
src 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
SKILL.md (800 tokens - Modular)
Validates foo syntax: DECLARE, arrays, nested arrays, function calls, loops.
Rules:
- DECLARE detected → load declaration.md
- detected → load array.md
- detected → load function-call.md
Template: [input] valid? [YES/NO]. Reason: [rule].
declaration.md (1,200 tokens):
First character must be uppercase. Cannot start with a number. Examples: DECLARE x, DECLARE foo
array.md (1,500 tokens):
Must use brackets: [item] References nested-array.md for [x] Examples: [foo], [bar], [123]

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.

src is a skill published in the GitHub repository mcsee/Software-Design-Articles (22 stars, last pushed 7d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 148 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 2026-08-30.
