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 | $0.00111 | $0.02671 |
| Opus 5 | $0.00056 | $0.01336 |
| Sonnet 5 | $0.00022 | $0.00534 |
| Haiku 4.5 | $0.00011 | $0.00267 |
Grade A, and why
legacy-circuit-mockups 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 7d 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.

Legacy Circuit Mockups
A skill for creating breadboard circuit mockups and visual diagrams for retro computing and electronics projects. This skill leverages HTML5 Canvas drawing mechanisms to render interactive circuit layouts featuring vintage components like the 6502 microprocessor, 555 timer ICs, EEPROMs, and 7400-series logic gates.
When to Use This Skill
- User asks to "create a breadboard layout" or "mockup a circuit"
- User wants to visualize component placement on a breadboard
- User needs a visual reference for building a 6502 computer
- User asks to "draw a circuit" or "diagram electronics"
- User wants to create educational electronics visuals
- User mentions Ben Eater tutorials or retro computing projects
- User asks to mockup 555 timer circuits or LED projects
- User needs to visualize wire connections between components
Prerequisites
- Understanding of component pinouts from bundled reference files
- Knowledge of breadboard layout conventions (rows, columns, power rails)

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.

legacy-circuit-mockups is a skill published in the GitHub repository boshi-xixixi/TraeSkill (263 stars, last pushed 4mo ago), licensed MIT. It adds 111 tokens to every session and 2,671 once invoked, about $0.0006 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 2026-09-03.
