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.

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 | $0.00042 | $0.00672 |
| Opus 5 | $0.00021 | $0.00336 |
| Sonnet 5 | $0.00008 | $0.00134 |
| Haiku 4.5 | $0.00004 | $0.00067 |
Grade A, and why
ios-memgraph-inspector 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 11d 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 — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.
iOS Memgraph Inspector
Before invoking Apple-only binaries, confirm the execution context is macOS. From Windows or Linux, run those steps in a Mac SSH project or through an already configured remote transport; do not retry missing Apple binaries locally.
Use for leaks from a live simulator process or existing .memgraph. Pair with ../ios-simulator-debugger/SKILL.md when build, launch, UI driving, logs, or screenshots are needed.
Workflow
- Build, launch, and drive the exact flow that should release objects.
- Capture with
scripts/capture_sim_memgraph.sh. - Summarize with
scripts/summarize_memgraph_leaks.py. - For app-owned leaked types, inspect ownership with
leaks --traceTree=<address> <file.memgraph>and grouped leak evidence. - Patch the smallest retaining edge, then recapture the same flow/simulator when possible.
- Report before/after counts, disappeared root types or paths, remaining leaks, memgraph paths, and build/test proof.
Do not claim a fix from a smaller memgraph alone; prove the specific type or ownership path disappeared.
Capture
SKILL_DIR is the loaded skill folder, not the app repo.
SKILL_DIR="<absolute path to this loaded skill folder>"
SIM="<simulator-udid>"
BUNDLE_ID="<app.bundle.identifier>"
MEMGRAPH_DIR="$(mktemp -d "${TMPDIR:-/tmp}/codex-ios-memgraph.XXXXXX")"
"$SKILL_DIR/scripts/capture_sim_memgraph.sh" \
--udid "$SIM" \
--bundle-id "$BUNDLE_ID" \
--out-dir "$MEMGRAPH_DIR"
If the process is missing, verify the bundle id and inspect running labels:
xcrun simctl spawn "$SIM" launchctl list
Summarize:
"$SKILL_DIR/scripts/summarize_memgraph_leaks.py" \
/path/to/app.memgraph \
--trace-limit 5 \
--out /path/to/leak-summary.md
Use --trace-limit sparingly. If traceTree says Found 0 roots referencing, treat it as an unreachable/self-retained candidate and inspect leaks --groupByType <file.memgraph> plus source.
Root-Cause Rules
- Identify the first app-owned leaked type.
- Determine intended lifetime: process, session, account, view, request, or task.
- Lazy allocation is scope reduction, not proof of a fixed leak.
- Prove retain cycles with
traceTreeor an isolated repro. - Separate framework/runtime noise from app-owned branches.
- Prefer removing the retaining edge over broad cleanup code.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

ios-memgraph-inspector is a skill published in the GitHub repository Xopoko/build-swift-apps (45 stars, last pushed 14d ago), licensed MIT. It adds 42 tokens to every session and 672 once invoked, about $0.0002 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.
Other skills, from other repositories
firebase-crashlytics
Use when implementing crash reporting, capturing fatal/non-fatal errors, recording isolate/async exceptions, customizing reports, or uploading obfuscated symbols.
flutter-errors
Use when hitting layout errors (RenderFlex overflow, unbounded constraints, RenderBox not laid out), scroll errors, or setState-during-build errors.
push-notification-tester
Test VoIP push notifications for Telnyx WebRTC iOS (APNs) and Android (FCM) apps. Use when debugging push notification delivery, validating certificate/credential setup, or testing that a device receives VoIP pushes correctly.
mobile-emulator-start
Boot Android emulator + Metro (Expo / bare RN) in order: inspect IDE terminals, kill stale ports, pick an AVD. Use when "start Metro", "start emulator", "Cannot connect to Expo", or a stuck dev loop. QA on the running emulator → mobile-emulator-test.
apple-cleanup
Exhaustive engineering hardening of an iOS app. Reviews for Swift 6 compliance, crash risks, App Store rejection risks, and tech debt; builds a surgical plan; dispatches parallel subagents to fix all P0-P2 issues; then pushes an alpha to TestFlight. Use for pre-submission cleanup and code hardening, not design polish.
apple-polish
Design and keynote-readiness craftsmanship review of an iOS app. Evaluates through Jony Ive (visual obsession) and Steve Jobs (demo readiness) perspectives, presents prioritized findings, then orchestrates parallel agents to fix selected issues and push a TestFlight build. Use for design polish, not engineering bugs.
