soc2-rails

soc2-rails is a skill for Claude Code, Codex from sandeepmvl/rails-skills. It costs 127 tokens per session (2,798 once invoked), scanned A, original, MIT.

A guide to preparing a Rails application for SOC 2, an independent audit report about controls for security, availability, accurate processing, confidentiality, and privacy. It focuses on the engineering work needed alongside company policies and procedures.

In plain words
What is it for?
Use it to plan audit logs, access reviews, multi-factor authentication, change approval through pull requests and CI, vendor records, and integrations with compliance platforms such as Drata, Vanta, or Secureframe.
Why use it?
It helps teams gather evidence for customer security reviews and audits instead of relying on informal processes. It clarifies the difference between Type I, which assesses controls at one point in time, and Type II, which assesses them over a period.

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

soc2-rails 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 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.

SOC 2 for Rails

SOC 2 is the de-facto enterprise procurement requirement. Most US-based B2B SaaS deals over ~$25k/year now demand a SOC 2 Type II report. Getting compliant is 60% policies + procedures (Drata/Vanta-shaped), 40% engineering. This skill covers the engineering 40%.

The opinion

Adopt a compliance vendor (Drata, Vanta, Secureframe) from day one — DIY SOC 2 is a quagmire. The vendor handles ~80% of evidence collection via integrations. Engineering's job: audit logs that survive deletion, automated access reviews via SCIM, change-management via PR review + CI, vendor inventory, MFA on every privileged surface. Aim for SOC 2 Type II from the start — Type I is a snapshot; Type II covers a period (typically 6-12 months) and is what customers want to see.

Trust Services Criteria

SOC 2 is built on the 5 TSCs. You pick which apply:

TSC Required? What it covers
Security Always Access controls, change management, monitoring
Availability If you offer uptime SLA Capacity, backup, BCDR
Processing Integrity If you process customer data accurately matters Data quality, processing correctness
Confidentiality If you handle confidential customer data Encryption, NDA, deletion
Privacy If you handle personal data (often paired with GDPR/CCPA) Consent, retention, breach notification

Most B2B SaaS: Security + Availability + Confidentiality. Sometimes Privacy.

Pattern 1: Audit logs that survive

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.
