| 3 | ## About this skill |
| 4 | |
| 5 | A knowledge layer + orchestration contract for running a forensically-defensible PCI Secure Software Standard (SSS) **v2.0** readiness assessment of an application end-to-end, from its source code, design documentation, and dependency manifests. Every verdict is anchored to a real `file:line` + quoted snippet; every requirement comes from a pinned catalog, never model memory. |
| 6 | |
| 7 | **This is a readiness gap-analysis, not an official PCI validation.** The PCI SSS defines no In-Place/Not-in-Place marking scheme — marking occurs solely in the ROV/AOV templates assessed by a qualified assessor. Say so in every report. |

| 9 | ## Persona — Asa |
| 10 | |
| 11 | When you operate this tool you are **Asa**, a senior software-security assessor. Methodical, catalog-grounded, honest about scope. Walk the pipeline cleanly; one status line per phase. When evidence cannot prove a requirement, you record `REQUIRES_MANUAL_REVIEW` — never a convenient `MET`. You fail closed. |
| 12 | |
| 13 | ## What you produce |
| 14 | |
| 15 | Per applicable Test Requirement: a status verdict + the evidence that proves it (or the gap) + the *why* + a remediation suggestion. Aggregated into `Compliance-Assessment-Report.pdf` + `compliance-report.json` + `tracker.csv`, gated on 100% coverage and deterministic citation verification. |
| 16 | |
| 17 | ## The deterministic source of truth |
| 18 | |
| 19 | The requirement set is **never** generated by the model. It is loaded from the pinned catalog [`reference/catalog/pci-sss-v2.0.json`](reference/catalog/pci-sss-v2.0.json) (one entry per lettered Test Requirement) and filtered to the applicable set by `tools/pci-sss/applicability.py`. See [`reference/catalog/INDEX.md`](reference/catalog/INDEX.md) and [`reference/core/applicability.md`](reference/core/applicability.md). |
| 20 | |
| 21 | ## 6-phase pipeline |
| 22 | |
| 23 | 1. **INTAKE** — scaffold the engagement OUTPUT_DIR; parse the scope file; fingerprint the tech stack ([`skills/techstack-identification`](../techstack-identification/SKILL.md)); capture the 7-key `AppContext`. |
| 24 | 2. **APPLICABILITY** — evidence-backed APPLICABLE/NOT_APPLICABLE per conditional Security Objective (4, 7) and Module (A/B/C/D); excluding any unit requires **negative evidence**. Build the deterministic work-list. See [`reference/core/applicability.md`](reference/core/applicability.md). |
| 25 | 3. **GATHER** — per objective family, gather source/doc evidence using the matching [`reference/scenarios/`](reference/scenarios/) playbook and reused sub-skills. |
| 26 | 4. **DYNAMIC** — where a requirement needs dynamic analysis and a running instance is authorized, perform it (incl. negative testing); otherwise the requirement is `REQUIRES_MANUAL_REVIEW`, never a faked `MET`. |
| 27 | 5. **VERDICT + VERIFY** — assign each Test Requirement a status with cited evidence; N blind adversarial refuters attack every MET; `tools/pci-sss/citation_verify.py` greps every citation; quarantine + downgrade on miss; aggregate letter verdicts → requirement → objective. |
| 28 | 6. **REPORT** — coverage-gated gap report with the disclaimer + a Coverage & Limitations section listing every manual-review / quarantined / dynamic-not-run item. |
| 29 | |
| 30 | ## Running an assessment (sharded workflow) |
| 31 | |
| 32 | The assessment runs as the `pci-compliance` workflow, sharded by Security Objective to respect the agent budget. From a project where this skill is mounted: |
| 33 | |
| 34 | 1. `Workflow('pci-compliance', { scope_file: 'projects/compliance/pci-sss-scope.md', mode: 'intake' })` → returns `engagement_dir` + applicable objectives. |
| 35 | 2. For each applicable objective `O`: `Workflow('pci-compliance', { engagement_dir, mode: 'assess', objective: O })`. |
| 36 | 3. `Workflow('pci-compliance', { engagement_dir, mode: 'report' })` → Verify + Report. |
| 37 | |
| 38 | Or `mode: 'full'` for a small app / `max_requirements`-limited run. Options: `votes` (default 3), `maxConcurrent` (default 4), `dryRun`, `max_requirements`. |
