data-handling-template

data-handling-template is a skill for Claude Code from MingyiSecLab/Mingyi-Atlas. It costs 37 tokens per session (832 once invoked), scanned A, original, Apache-2.0.

A data-handling plan generator for recording what evidence an engagement collects, where it is stored, how long it remains available, and who can access it. It covers classes such as credentials, personal information, source code, and business data.

In plain words
What is it for?
It is for defining retention, classification, encryption, access, and chain-of-custody rules for red-team evidence and sensitive client data.
Why use it?
It turns vague evidence-storage decisions into explicit handling rules and connects them to compliance frameworks such as GDPR, HIPAA, PCI-DSS, and SOC 2.

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

data-handling-template 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 6d 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.

Data Handling Plan Generator

The data handling plan defines what evidence the agent collects, where it lives, how long it's kept, and who can read it. Replaces the deprecated free-form RoE.data_handling string with structured per-class fields.

When to Use

  • After RoE is written (RoE constraints + scope drive which data classes appear)
  • User says "create data handling", "retention policy", "evidence storage", "PII handling", "compliance"

Workflow

Step 1: Start From the Schema Defaults

The DataHandlingPlan schema seeds four default classes — credentials, pii, source-code, business-data — with conservative retention. Keep these by default; override only when the engagement requires stricter or looser rules.

Step 2: Add Engagement-Specific Classes

Based on the interview:

Engagement type Likely additional classes
Healthcare client health-records (classification: secret, retention: 7 days, framework: HIPAA)
Financial client cardholder-data (classification: secret, retention: 0 days — never store, framework: PCI-DSS)
EU client / data subjects Mark existing pii with framework: GDPR; consider personal-data-eu for stricter handling
Defense / classified controlled-unclassified (classification: secret, retention: 0 days off-network)

Step 3: Set Evidence Storage Path

Default "/workspace/<engagement>/evidence/" works for sandbox-isolated engagements. Override only when:

  • Engagement requires an external-bucket destination (S3 / Azure Blob with client KMS)
  • Multiple engagement workspaces share an evidence repository

Step 4: Compliance Frameworks

Set compliance_frameworks from the interview. Common entries: GDPR, HIPAA, PCI-DSS, SOC2, NIST 800-53, FedRAMP, ISO 27001.

The orchestrator (Atlas) reads this list and refuses to start objectives that violate the matching framework's evidence-handling rules.

Step 5: Purge Hard Cap

purge_after_days is the GLOBAL upper bound — every artifact older than this is deleted regardless of per-class retention. Default 90 days; reduce for engagements with tighter regulatory exposure.

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.
