SkillSpector: 14 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 →

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 | $0.00209 | $0.01835 |
| Opus 5 | $0.00105 | $0.00918 |
| Sonnet 5 | $0.00042 | $0.00367 |
| Haiku 4.5 | $0.00021 | $0.00184 |
Grade A, and why
dart-lifecycle-disposed-flag-overload 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.

Dart Lifecycle _disposed Flag Overload
Problem
A Dart/Flutter class with start/stop lifecycle methods sets a "disposed"/"stopped"
boolean inside stop(), but the guard clause in start() short-circuits whenever
that boolean is true. After a stop→start cycle, start() silently returns without
doing anything. The class has two distinct concerns conflated into one flag:
- "This instance is permanently torn down" (e.g. user switched accounts, object is being discarded) — should prevent any further work.
- "Currently not listening, but could be re-started" (e.g. user navigated away
from the inbox screen and may come back) — must allow future
start()calls.
When those concerns share a single flag, the second concern silently breaks the first.
Context / Trigger Conditions
- A class (repository, service, controller, bloc, cubit, notifier) has methods like:
startListening()/stopListening()subscribe()/unsubscribe()connect()/disconnect()open()/close()
stop()includes a line like_disposed = true;or_stopped = true;start()begins with a guard like:if (_subscription != null || _disposed || !isInitialized) return;- Symptom: the feature works on first open, breaks on every subsequent open
- Unit tests that mock the dependencies pass because they only exercise one cycle OR because the mock doesn't model the real instance's internal state
- Manual QA finds that leaving and returning to a screen breaks the feature silently (no error thrown, no log emitted, no visible indication)
Solution
Separate the two concerns. Reserve the permanent-teardown flag for the code path
that actually tears the instance down for good (typically a _resetState() called on
user-switch or full logout), and do NOT set it inside stop().
Before (broken)
class MyRepository {
bool _disposed = false;
StreamSubscription<Event>? _subscription;
void startListening() {
if (_subscription != null || _disposed || !isInitialized) return;
_subscription = _client.subscribe(...).listen(...);
}
Future<void> stopListening() async {
_disposed = true; // ← THE BUG
await _subscription?.cancel();
_subscription = null;
}
void _resetState() {
_disposed = true;
// ... wipe credentials ...
_disposed = false;
}
}
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.

dart-lifecycle-disposed-flag-overload is a skill published in the GitHub repository divinevideo/divine-mobile (264 stars, last pushed today), licensed MPL-2.0. It adds 209 tokens to every session and 1,835 once invoked, about $0.0010 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.
