Token cost

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.

Security

Grade A, and why

axiom-code-signing-ref scanned grade A with 1 finding 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 5d 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.

Code Signing API Reference

Comprehensive CLI and API reference for iOS/macOS code signing: certificate management, provisioning profile inspection, entitlement extraction, Keychain operations, codesign verification, fastlane match, and Xcode build settings.

Quick Reference

# Diagnostic flow — run these 3 commands first for any signing issue
security find-identity -v -p codesigning          # List valid signing identities
security cms -D -i path/to/embedded.mobileprovision  # Decode provisioning profile
codesign -d --entitlements - MyApp.app             # Extract entitlements from binary

Certificate Reference

Certificate Types

Type Purpose Validity Max Per Account
Apple Development Debug builds on registered devices 1 year Unlimited (per developer)
Apple Distribution App Store + TestFlight submission 1 year 3 per account
iOS Distribution (legacy) App Store submission (pre-Xcode 11) 1 year 3 per account
iOS Development (legacy) Debug builds (pre-Xcode 11) 1 year Unlimited
Developer ID Application macOS distribution outside App Store 5 years 5 per account
Developer ID Installer macOS package signing 5 years 5 per account
Apple Push Services APNs .p12 certificate auth (legacy) 1 year 1 per App ID

CSR Generation

# Generate Certificate Signing Request
openssl req -new -newkey rsa:2048 -nodes \
  -keyout CertificateSigningRequest.key \
  -out CertificateSigningRequest.certSigningRequest \
  -subj "/[email protected]/CN=Developer Name/C=US"

Or use Keychain Access: Certificate Assistant → Request a Certificate From a Certificate Authority.

Certificate Inspection

# View certificate details (from .cer file)
openssl x509 -in certificate.cer -inform DER -text -noout

# View certificate from .p12
openssl pkcs12 -in certificate.p12 -nokeys -clcerts | openssl x509 -text -noout

# List certificates in Keychain with SHA-1 hashes
security find-identity -v -p codesigning

# Example output:
#   1) ABC123... "Apple Development: [email protected] (TEAMID)"
#   2) DEF456... "Apple Distribution: Company Name (TEAMID)"
#      2 valid identities found

# Find specific certificate by name
security find-certificate -c "Apple Distribution" login.keychain-db -p

# Check certificate expiration (pipe PEM output to openssl)
security find-certificate -c "Apple Distribution" login.keychain-db -p | openssl x509 -noout -enddate

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.
