sensitive-data

sensitive-data is a skill for Claude Code, Codex from griddynamics/rosetta. It costs 87 tokens per session (366 once invoked), scanned A, original, Apache-2.0.

A safety rule for handling sensitive information such as personal data, passwords, API keys, credentials, and medical or financial records. It tells the agent to avoid exposing or storing such data.

In plain words
What is it for?
Use it whenever coding work may read, process, or output confidential information. It covers data handling in source files, configuration, logs, tool results, and responses.
Why use it?
It reduces the risk of secrets or regulated information appearing in messages, files, logs, or summaries. If sensitive data is encountered, it requires masking it and reporting only that it was found.

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

sensitive-data 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 5d 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.

What it actually says

<sensitive_data>

  1. DO NOT read, query, store, tell, write, log, or distribute any SENSITIVE information (PII, PCI, HIPAA, PHI, GDPR, SOC2, FedRAMP, Secrets, etc)
  2. IF encountered — report without exposing raw value
  3. IF needed as-is — MUST ask explicit user approval first
  4. User may override (mocked data)
  5. NEVER output, echo, print, log, summarize, or reference the raw value of any sensitive data in chat or in any file
  6. MASK immediately using [REDACTED:<type>] (e.g. [REDACTED:API_KEY], [REDACTED:PASSWORD])
  • DO NOT read, query, store, tell, write, log, or distribute any SENSITIVE information
  • Identify and apply respective guidance for handling data like that
  • Guide user for correct implementation
  • Echoing secrets in summaries or diffs.
  • Logging sensitive data to AGENT MEMORY.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.
