sub-ghz

Sub-GHz RF capture and replay for 433/868/915 MHz ISM-band targets (garage doors, car keys, alarm sensors, weather stations). Covers fixed-code replay with HackRF/Flipper Zero/RTL-SDR, rolling-code analysis with rfcat, signal visualization with inspectrum and Universal Radio Hacker, and encoding/modulation identification.

Quality

Content

82%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A dense, actionable, well-sequenced skill body with strong copy-paste commands and clear phase structure, held back only by minor over-explanation and the lack of explicit pre-transmit validation checkpoints.

Suggestions

Add an explicit validation checkpoint before any transmit/replay step (e.g., 'Verify the decoded signal matches the target device in rtl_433/URH before transmitting') to raise workflow clarity.

Trim the inline modulation/rolling-code definitions that Claude already knows, or move them to a short glossary, to improve conciseness.

Consider splitting the protocol-specific crafting (PT2262 encoder) and rolling-code analysis into reference files to improve progressive disclosure for this longer skill.

Dimension	Reasoning	Score
Conciseness	Mostly efficient and dominated by concrete commands/code, with minor over-explanation (e.g., 'OOK (On-Off Keying) = on/off pattern; FSK = two frequencies' and the rolling-code counter explanation) that could be trimmed.	4 / 5
Actionability	Fully executable, copy-paste ready commands and code covering the common cases — rtl_sdr/hackrf_transfer capture, rtl_433 decode, inspectrum/URH analysis, rfcat transmit, and the PT2262 IQ encoder — with complete flags and parameters.	5 / 5
Workflow Clarity	Five clearly sequenced phases (capture → analyze → replay → rolling-code → craft) with implicit verification via rtl_433 decode and IQ burst trimming before replay; minor validation gaps before transmit keep it just below 5.	4 / 5
Progressive Disclosure	Well-organized into clearly headed sections (Prerequisites, Frequency Reference, Phases 1–5, Evidence, OPSEC, References) with a clearly signaled external References list; no bundle files exist, and structure is good with only minor opportunity to split protocol-specific detail out.	4 / 5

Description

82%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A highly specific, well-targeted description with strong trigger keywords and low conflict risk, weakened only by the absence of an explicit 'Use when...' trigger clause that caps completeness.

Suggestions

Add an explicit trigger clause such as 'Use when working with sub-GHz RF, 433/868/915 MHz devices, or when the user mentions garage doors, keyfobs, or replay attacks.' to lift completeness above 3.

Consider including common file extensions or artifact names (e.g., .sub, .iq, .cu8) as additional trigger terms users may mention.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions ('RF capture and replay', 'fixed-code replay', 'rolling-code analysis', 'signal visualization', 'encoding/modulation identification') plus specific tools and targets, giving comprehensive coverage of the domain.	5 / 5
Completeness	The 'what' is clearly and comprehensively stated, but there is no explicit 'Use when...' clause; the 'when' is only weakly implied via the parenthetical target list, so per the missing-trigger-guidance cap the score stays at 3.	3 / 5
Trigger Term Quality	Comprehensive natural keyword coverage including frequencies (433/868/915 MHz), tool names (HackRF, Flipper Zero, RTL-SDR, rfcat, inspectrum, Universal Radio Hacker), device types (garage doors, car keys, weather stations), and synonyms (replay, rolling/fixed code, ISM band).	5 / 5
Distinctiveness Conflict Risk	A clear niche (sub-GHz ISM-band RF capture/replay) with distinct frequency, tool, and device triggers that make overlap with other skills minimal.	5 / 5
