import-legacy-ssp

import-legacy-ssp is a skill for Claude Code, Cursor from oscal-compass-lab/compliance-trestle-skills. It costs 43 tokens per session (783 once invoked), scanned A, original, Apache-2.0.

A workflow for importing an older system security plan or related PDF, DOCX, or Markdown package into an OSCAL Document Workbench workspace. OSCAL is a structured format for describing security and compliance information, while Trestle helps manage OSCAL documents.

In plain words
What is it for?
Use it to create a traceable workspace from legacy security documents, extract source text, bootstrap a Trestle project, and optionally apply NIST or FedRAMP baselines when appropriate.
Why use it?
It preserves the original source, extracts its structure, maps content to the new workspace, and validates the imported result.

Skill for Claude CodeCursor

Written for Claude Code and Cursor: disable-model-invocation in frontmatter, but also installed under .cursor/. Also seen: mentions AGENTS.md.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is bash plugins/document-transform/oscal-document-workbench/scripts/extract-legacy-doc.sh <input> --output <workspace>/extracted.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

import-legacy-ssp scanned grade A with 0 findings 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Import Legacy SSP

Run the full legacy SSP import workflow for Cursor.

Before you start

Read:

  • AGENTS.md
  • agent-skills/oscal-document-engineering/SKILL.md
  • agent-skills/compliance-trestle-engineering/SKILL.md
  • plugins/document-transform/oscal-document-workbench/commands/ingest-ssp.md

This repository is an OSCAL and Compliance Trestle toolkit. FedRAMP Rev 5 heading maps and 20x KSI coverage are optional adapters. They are not the default product claim.

Steps

  1. Make sure you know the source files and the target workspace path. Usual path: workspaces/<system>-ssp-import/.
  2. Copy source documents into input/.
  3. Do not change the original files.
  4. Extract source text and section structure:
bash plugins/document-transform/oscal-document-workbench/scripts/extract-legacy-doc.sh <input> --output <workspace>/extracted
  1. Bootstrap or reuse a Compliance Trestle workspace:
bash plugins/document-transform/oscal-document-workbench/scripts/bootstrap-trestle-workspace.sh <workspace> [--profile <name>]
  1. Optionally import a real NIST or FedRAMP baseline when the source is a FedRAMP-style SSP:
bash plugins/document-transform/oscal-document-workbench/scripts/fetch-oscal-baseline.sh <workspace>/trestle-workspace --baseline moderate
  1. Draft a schema-valid SSP from extracted sections when Trestle is available:
bash plugins/document-transform/oscal-document-workbench/scripts/draft-ssp-from-extraction.sh <workspace> [--baseline-profile fedramp-rev5-moderate] [--overwrite]

Omit --baseline-profile to make offline stub catalog and profile models. Replace stubs before authorization use. For non-FedRAMP sources, do not treat the FedRAMP heading map as authoritative. Keep unmatched sections needs_review.

  1. Map remaining content in source-map.csv. Mark uncertain mappings as needs_review. Do not invent compliance facts.
  2. Build the review queue:
bash plugins/document-transform/oscal-document-workbench/scripts/build-review-queue.sh <workspace>/extracted/source-map.csv --output <workspace>/reports/review-queue.md

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.
