Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00071 | $0.00542 |
| Opus 5 | $0.00036 | $0.00271 |
| Sonnet 5 | $0.00014 | $0.00108 |
| Haiku 4.5 | $0.00007 | $0.00054 |
Grade A, and why
anonymize-doc scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
PII & Business Data Anonymization
Detect and anonymize PII + sensitive business data using ML-powered detection (Scrubadub + spaCy NER).
Instructions
0. Dependency Check
SKILL_DIR="$(dirname "$(realpath "$0")" 2>/dev/null || echo /home/mat/dev/agent-skills/dstoic/skills/anonymize-doc)"
pip install -q -r "$SKILL_DIR/requirements.txt" && python -m spacy download -q en_core_web_sm 2>/dev/null
1. Ask Mode
Question: "Check for PII/business data (detection only) or anonymize?"
2. Detection
- Run:
python "$SKILL_DIR/scripts/detect.py" <file_path> - Parse JSON output → format report (type, line/col, severity, category)
- Ask: "Proceed with anonymization?"
3. Anonymization
Ask strategy:
| Strategy | Use Case | Reversible | GDPR |
|---|---|---|---|
mask |
Max privacy, redaction | No | ✅ Full |
hash |
Analytics, tracking | No | ✅ Full |
pseudo |
Demos, case studies | Yes | ⚠️ Partial |
token |
Financial, vault-backed | Yes | ⚠️ Partial |
mixed |
Complex docs (auto per severity) | Mixed | ⚠️ Partial |
Run: python "$SKILL_DIR/scripts/anonymize.py" <file_path> --strategy <choice>
Outputs: <file>-anonymized.<ext> + <file>-audit-log.json
4. Safety Rules
- Preserve original file — never overwrite
- Never commit audit logs to git — check
.gitignorehas*-audit-log.json - Warn: reversible strategies need secure mapping storage
- GDPR requires irreversible (mask/hash) for full compliance

What ships with it
8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

anonymize-doc is a skill published in the GitHub repository digital-stoic-org/agent-skills (20 stars, last pushed 4d ago), licensed MIT. It adds 71 tokens to every session and 542 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
