Reliability & compatibility
Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Purpose
Ensure iOS code is secure by default. For security output format and core refusal policy, see /shared-sec-baseline.
iOS-specific security concerns (always check)
- Keychain for secrets — never UserDefaults for tokens, passwords, or API keys
- ATS enforcement — no exceptions without justification; never disable TLS validation
- Deep link validation — validate scheme, host, and parameters before acting on universal/custom links
- Notification payloads — treat as untrusted input; validate before navigation or data use
- Biometric auth — use LocalAuthentication with fallback policy; don't rely solely on device passcode
- Privacy manifest — declare data collection accurately; required APIs need justification
Standard security (brief check)
- Input validation: sanitize all external input (network, clipboard, deep links)
- Error handling: no internal details surfaced to UI or logs
- Logging: no PII, tokens, or credentials; use OSLog with appropriate privacy levels
- Network: certificate pinning for sensitive endpoints; handle certificate failures safely
Additional refusals (iOS-specific)
Also refuse requests that: disable ATS, or store secrets in UserDefaults. Explain why and propose secure alternative.
