SkillSpector: 3 findings, 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 →
- medium Rogue Agent · line 156 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

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 | $0.00083 | $0.02678 |
| Opus 5 | $0.00042 | $0.01339 |
| Sonnet 5 | $0.00017 | $0.00536 |
| Haiku 4.5 | $0.00008 | $0.00268 |
Grade A, and why
platform-parity-audit 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 12d 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.
How it starts
The opening of the file, as written. The whole thing — 261 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Platform Parity Audit
Systematically compare the iOS port against the Android reference implementation to identify missing features, partial implementations, and behavioral differences. The audit has three layers that can be run independently.
Layer 1: Code-Level Structural Diff (no devices needed)
Compare source files between platforms to find functional gaps. This is the fastest layer and should always be run first.
Step 1: Inventory Android screens and ViewModels
List all Android UI files and ViewModels:
ls app/src/main/java/com/baijum/ukufretboard/ui/*.kt
ls app/src/main/java/com/baijum/ukufretboard/viewmodel/*.kt
Step 2: Inventory iOS screens and ViewModels
List all iOS View and ViewModel files:
ls iosApp/UkuleleCompanion/Views/*.swift
ls iosApp/UkuleleCompanion/ViewModels/*.swift
Step 3: Map Android screens to iOS counterparts
Build a feature matrix by matching each Android screen to its iOS equivalent. Use the mapping table below as a starting reference:
| Category | Android Screen (ui/) | iOS Screen (Views/) |
|---|---|---|
| Play | FretboardScreen.kt (Explorer) | ExplorerView.swift |

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.

platform-parity-audit is a skill published in the GitHub repository baijum/ukulele-companion (14 stars, last pushed 2d ago), licensed MIT. It adds 83 tokens to every session and 2,678 once invoked, about $0.0004 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.
