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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00176 | $0.07049 |
| Opus 5 | $0.00088 | $0.03524 |
| Sonnet 5 | $0.00035 | $0.01410 |
| Haiku 4.5 | $0.00018 | $0.00705 |
Grade A, and why
windows-ops 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 4d 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.

Helps with
Slow boot on a Windows machine that used to be fast — bloat accumulation across the five startup mechanisms (registry Run keys, services, scheduled tasks, startup folders, group policy). The same machine still boots fast once those are inventoried and trimmed.
Failing drives that nobody's spotted yet. The signal lives in System log Events 7 / 52 / 153 / 154 (disk bad block, paging error, retry, hardware error) and storahci Event 129 ("Reset to device, \Device\RaidPortN, was issued"). Healthy drives produce zero of these — hundreds in a month means active failure even when SMART still claims "Healthy."
Crashes with no obvious cause. Event 41 (Kernel-Power) carries the BugCheck code at Properties[0] and four parameters at Properties[1-4]. A 0xEF (CRITICAL_PROCESS_DIED), 0xD1 (DRIVER_IRQL), 0x124 (WHEA uncorrectable), or 0x0 (no bugcheck recorded → hard power loss) each implies a completely different fix.
"My PC is slow" diagnosed by chasing the wrong symptom. Task Manager shows what's running NOW; the System log shows what failed at boot, what's been crashing, and what storage events preceded each crash. Always audit before treating.
Unable to disable an HKLM startup entry because the user isn't an Administrator. The StartupApproved registry mechanism — what Task Manager's "Disable" button actually does — flips one byte in HKCU\...\Explorer\StartupApproved\Run and works without elevation, even for HKLM entries.
BSOD analysis without a dump file. Pagefile too small, or hard power loss skipped the dump-write. CrashDumpEnabled registry key + pagefile size + free space on system drive determine whether the next crash gets diagnosed at all.
Pre-crash timeline correlation. The events in the 10 minutes BEFORE Event 41 are where the story is. storahci resets before a crash → storage failure cascade. nvlddmkm / igdkmd64 warnings before crash → GPU driver hang. WHEA events before crash → hardware fault.
Identifying which physical drive is failing when the symptom is "Disk 1" or "\Device\Harddisk1" in an event message. Maps physical disk number ↔ drive letter ↔ controller port ↔ model + firmware, so the user knows which SATA cable to unplug.

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.
- 4d ago First seen · 415 lines · 176 tokens per session scan A e5f1a8d08afd
windows-ops is a skill published in the GitHub repository 0xDarkMatter/claude-mods (33 stars, last pushed 15d ago), licensed MIT. It adds 176 tokens to every session and 7,049 once invoked, about $0.0009 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.

Find out what an unknown USB/Bluetooth HID button actually emits without assuming the label or documentation. Uses Karabiner's.

When a fault is localized and the proximate cause is known but the systemic root is not, chain evidence-linked whys with a counterfactual stop and a countermeasure.
thinking-scientific-method
When a symptom has several plausible causes, rank falsifiable hypotheses and run the cheapest discriminating observation first; prefer least-assumptive survivors only after evidence fit.

When a claim, doc, test, metric, or assumption conflicts with observed behavior, stop theorizing from the map and verify the live code or data; let territory overrule.
