What it costs to keep this loaded
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 | $0.00057 | $0.01981 |
| Opus 5 | $0.00028 | $0.00991 |
| Sonnet 5 | $0.00011 | $0.00396 |
| Haiku 4.5 | $0.00006 | $0.00198 |
Grade A, and why
analyze-power-nets 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 8d 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.

Analyze Power Nets
When this skill is invoked, perform a full AI-powered analysis of the PCB to identify power nets and recommend track widths.
Step 1: Load and Extract Components
from analyze_power_paths import (
analyze_pcb, get_components_needing_analysis, classify_component,
trace_power_paths, get_power_net_recommendations, format_analysis_report,
ComponentRole
)
components, pcb_data = analyze_pcb("path/to/file.kicad_pcb")
unknown = get_components_needing_analysis(components)
Step 2: Auto-Classify Obvious Components
These are already handled automatically - no AI needed:
| Prefix | Role | Reason |
|---|---|---|
| R (resistor) | SHUNT | Pull-ups, voltage dividers |
| C (capacitor) | SHUNT | Decoupling caps |
| L (inductor) | PASS_THROUGH | Series filter element |
| FB (ferrite bead) | PASS_THROUGH | Series filter element |
| F (fuse) | PASS_THROUGH | Series protection |
| LED | CURRENT_SINK | Consumes current |
| SW (switch) | PASS_THROUGH | Power switching |
Step 3: AI Analysis for Unknown Components
For each component in the unknown list, you MUST:
3a. Identify What It Is
Use WebSearch to look up the component:
WebSearch: "<part_value> <footprint_hint> datasheet"
Examples:
"DB9 connector pinout"- Is it signal or power?"1N4004 diode datasheet"- Rectifier vs signal diode"3906 transistor datasheet"- Power switch or signal amp?"LT1129 regulator datasheet"- Voltage regulator specs"MCF5213 power consumption"- IC current requirements
3b. Determine Its Role
Based on the datasheet/search results, classify as:
| Role | Criteria |
|---|---|
| POWER_SOURCE | Supplies current to the board: power jacks, battery connectors, regulator outputs, USB power inputs |
| CURRENT_SINK | Consumes significant current: ICs, MCUs, CPLDs, FPGAs, motor drivers, high-power LEDs |
| PASS_THROUGH | Current flows through it: power switches, transistors used as switches, protection diodes in series |
| SHUNT | Branches off the power path: ESD protection diodes, TVS diodes, signal connectors |
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.

analyze-power-nets is a skill published in the GitHub repository drandyhaas/KiCadRoutingTools (395 stars, last pushed today), licensed MIT. It adds 57 tokens to every session and 1,981 once invoked, about $0.0003 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.
