SOC 2 Readiness Skill

A SOC 2 audit fails on two things: missing controls and missing evidence of controls you actually

run. This skill scopes the engagement to the right Trust Services Criteria, assesses each control's

status honestly, scores readiness deterministically (so "we're basically ready" becomes a number), and

turns the gaps into a prioritised, owned remediation plan with the evidence each control must produce.

Required Inputs

Ask for these only if they aren't already provided:

• Report type & period — SOC 2 Type I (point in time) or Type II (a window, usually 3–12 months).
• In-scope criteria — Security (always), plus any of Availability, Confidentiality, Processing Integrity, Privacy. Don't include criteria you can't evidence.
• Systems in scope — the product/infra boundary the report covers.
• Current control state — what's implemented, partially implemented, or missing (be honest; auditors test, they don't take your word).

Output Format

SOC 2 Readiness: [company] — [Type I/II], [period]

1. Scope — the systems, the in-scope criteria, and explicitly what's out of scope.

2. Control status — a table grouped by criterion; status is met / partial / gap.

| Criterion | Control | Status | Evidence it needs | Owner |

|---|---|---|---|---|

| Security (CC6) | Access reviews quarterly | partial | Signed access-review records | IT |

3. Readiness score — overall and per-criterion %, from the helper script (so it's consistent, not vibes). State the bar: a readiness assessment isn't a pass, but <~85% means you're not audit-ready.

4. Prioritised gaps — ranked by risk × effort: what to fix first, the owner, and the target date.

5. Evidence plan — for a Type II especially: what evidence must be collected continuously over the period (you can't backfill a quarter of access reviews the week before the audit).

Programmatic Helper

scripts/soc2_score.py (stdlib only) scores readiness from a control list so the number is

calculated, not estimated:

# controls.json: [{"criterion":"Security","control":"...","status":"met|partial|gap","weight":1}, ...]
python3 scripts/soc2_score.py controls.json
python3 scripts/soc2_score.py controls.json --json   # machine-readable, for chaining

It returns per-criterion and overall readiness (met=1.0, partial=0.5, gap=0) and lists the gaps.

Quality Checks

• [ ] Only criteria the org can actually evidence are in scope (don't add Privacy to look thorough)
• [ ] Every control names the specific evidence an auditor would request
• [ ] The readiness score is computed from the control list, not asserted
• [ ] For Type II, the plan distinguishes "implement the control" from "accumulate evidence over the period"
• [ ] Gaps are prioritised by risk and have an owner and date — not a flat list

Anti-Patterns

• [ ] Do not confuse a readiness assessment with a passed audit — readiness is self-assessed; the report comes from a licensed CPA firm
• [ ] Do not claim a control is "met" without the evidence to prove it — auditors test operating effectiveness, not intentions
• [ ] Do not over-scope criteria — every criterion you add is more controls to evidence; include only what's true and needed
• [ ] Do not leave gaps unowned or undated — an unowned gap is a gap that's still open at audit time
• [ ] Do not try to backfill Type II evidence — controls must demonstrably operate across the whole period
