Install with Codex or Claude Copy this prompt, paste it into Codex, Claude, or another assistant, and let it review the skill page and install it for you.
A direct command skips the review prompt. Inspect the source before running it.
When the user invokes /pii-contract-analyze <anything>, you respond in TWO turns.
Turn 1 — acknowledge and wait
Do NOT call any tool. Do NOT read files. Do NOT run Bash. Reply with one short line and stop:
Ready to start. Type go or continue to proceed.
Wait for the user's next turn. The MCP deferred-tools registry is often not populated yet on turn 1; it lazy-loads between turns.
Turn 2 — discover and proceed
When the user replies with any continue signal (go, continue, yes, ok, proceed, or equivalents in their language), silently run this discovery sequence:
If that returns "No matching deferred tools found": ToolSearch(query: "select:mcp__pii-shield__list_entities", max_results: 1)
If that also fails: ToolSearch(query: "select:mcp__plugin_pii-shield_pii-shield__list_entities", max_results: 1)
If any of them loads a schema → immediately call list_entities and continue with the Startup procedure, mode detection, and pipeline below. Do NOT surface these attempts to the user.
If all three fail → show the user:
PII Shield MCP tools are installed on your host (Claude Desktop) but this session can't reach them. Known Anthropic bridging bug on Windows. Fixes: (1) restart Claude Desktop and start a fresh session, or (2) install pii-shield-v2.0.1-plugin.zip directly into this Cowork session. Meanwhile I can proceed without PII anonymization — OK?
Rules
Never call ToolSearch on turn 1. The prompt "type go" is the whole turn-1 response.
Never fuzzy-search with bare keywords ("list_entities", "pii-shield") — underscore names don't match as substrings on Cowork CLI.
Never declare the plugin missing before turn-2's full three-attempt select: chain has run.
Never spawn sub-agents, grep the codebase, or probe filesystem paths / localhost ports / beacon files hunting for the server. If MCP tool discovery fails, the three select: attempts above are the whole fallback chain; anything beyond them is off-limits.
PII Shield — Universal Legal Document Processor
Anonymize → Work → Deanonymize → Deliver. Claude NEVER sees raw PII at any stage.
CRITICAL: PII never flows through Claude
File handling: The user must connect a folder (not attach the file directly to the message). When a file is attached to a chat message, its content is rendered and sent to the API as part of the prompt — Claude sees the raw data before PII Shield can process it. When a folder is connected, Claude only sees the file path and calls anonymize_file(path) — the MCP server reads and anonymizes the file locally. PII never enters Claude's context.
If the user attaches a file directly: Warn them politely: "For full PII protection, please connect the folder containing your document instead of attaching it directly. When a file is attached to a message, its content is included in the API request before PII Shield can anonymize it. I can still process it, but the privacy guarantee is stronger when you connect the folder."
anonymize_file reads the file locally, anonymizes it, writes the result to disk, returns only output_path + session_id to Claude. After HITL is approved, and only then, Claude reads the anonymized text from the output file — never before.
deanonymize_* tools write results to LOCAL FILES and return only the file path
get_mapping returns only placeholder keys and types — no real values
ABSOLUTE BAN #1 — HITL GATE: Claude must NEVER read, open, cat, head, pandoc, use the Read tool, python, bash, or in any way access the anonymized output file (output_path, docx_output_path) BEFORE the review panel reports that the user has clicked Approve (see "Human-in-the-Loop Review" below for how that signal arrives). Not to "preview entity quality", not to "verify placeholders", not to "check formatting", not to "plan the memo" — NEVER. The anonymized file is considered SEALED between anonymize_file and HITL approval. The HITL reviewer is the human, not Claude.
ABSOLUTE BAN #2 — DEANONYMIZED FILES: Claude must NEVER read, open, cat, head, pandoc, or in any way access the content of deanonymized/restored files. Not to "verify", not to "check formatting", not to "validate" — NEVER. These files contain real PII. Just give the user the file path and STOP. Any "verification" of deanonymized output is a PII leak.
Claude must NEVER read the source file (via Read tool, pandoc, python, bash, etc.) BEFORE or INSTEAD OF anonymization — always use anonymize_file(path) first
If an anonymize tool times out or fails with a NON-"tool not found" error — retry once. If it still fails, tell the user PII Shield is unavailable and ask whether to proceed without anonymization or abort. NEVER fall back to reading the raw file.
NEVER use anonymize_text or scan_text — these take raw text as input which means PII passes through the API. The ONLY exception is if the user explicitly pastes text into the chat (PII is already in the conversation).
Startup
PII Shield is a pure-Node.js MCP server — no Python dependency, instant startup. On first run, the NER model (~665 MB fp32 ONNX GLiNER) and its runtime deps (onnxruntime-node, @xenova/transformers, gliner) download into ${CLAUDE_PLUGIN_DATA}/models and ${CLAUDE_PLUGIN_DATA}/deps. This takes 2–5 minutes once per plugin install and is cached for the full life of the plugin (survives host restarts, only wiped by /plugin remove).
⛔ ABSOLUTE RULE — NO SUB-AGENT DELEGATION
NEVER delegate PII Shield tool calls to a sub-agent. Not to a general-purpose agent, not to a Task agent, not to an Explore agent — NEVER. Sub-agents do not stream text to the user; they return one final message only when they exit. If PII Shield is initializing, a sub-agent will poll silently for minutes while the user sees nothing. This is the single worst UX failure mode. All PII Shield tool calls (list_entities, anonymize_file, start_review, etc.) MUST happen in the MAIN conversation.
If you cannot call a PII Shield tool because it shows "No such tool available" — the fix is the turn-1 / turn-2 pattern above (prompt for go, discover silently on turn 2), NOT a sub-agent.
Startup procedure
Call list_entities — this happens on turn 2 after the user sends a continue signal. See the YOUR FIRST ACTION block at the top of this skill for the exact two-turn flow. You MUST have list_entities responding before proceeding.
Identify the file(s) to process and determine the mode (MEMO, REDLINE, etc.)
Read the list_entities response to check NER status
If "ner_ready": true — proceed to anonymize_file
If "ner_ready": false — NER is still initializing. The response includes phase (installing_deps / downloading_model / loading_model), progress_pct, a human message, and a pre-formatted user_message field. If the response ALSO contains a first_run_notice field (only present on the very first loading response per server process), print first_run_notice VERBATIM to the user as a plain chat message BEFORE anything else. It explains where the ~700 MB NER cache will live and why the next session will be instant — the user needs to see this once, up front. Subsequent polls will NOT contain first_run_notice. On every poll (including the first), print the user_message field VERBATIM to the user as a plain chat message BEFORE calling list_entities again. This is the ONLY thing the user sees during the wait — do not paraphrase, do not summarize, do not skip it, do not batch it silently. Wait and retry: the server enforces a ~20 second throttle by holding the list_entities response for 20 s internally while phase is installing_deps / downloading_model / loading_model. First run may take 2–5 minutes. Between polls (inside the 20 s window) you MAY do useful prep work in the MAIN conversation only — read skill references, plan the analysis. Do NOT delegate any of this to a sub-agent (see the ABSOLUTE RULE above). Do NOT call anonymize_file until ner_ready: true — without NER, only regex patterns work, missing PERSON/ORGANIZATION/LOCATION entities.
If "ner_error" field present — show it to the user. If "ner_error_suggestions" array is also present (platform-specific recovery steps like "install VC++ Redistributable", "switch to Node 22 LTS"), print each entry verbatim as a bulleted list — these are the concrete actions the user should try next. If "ner_error_diagnostic" object is present, its likely_cause field is a one-word root-cause tag useful to include in any bug report the user may file.
Loop: call anonymize_next_chunk(session_id) until status is "complete" — show "Anonymizing... [chunk X/Y]"
Call get_full_anonymized_text(session_id) to finalize — returns output_path, session_id, output_dir
Continue with the normal pipeline using the returned values
For short documents (<15K chars), anonymize_file processes everything in one call.
File path resolution
Call anonymize_file(file_path: "<path or filename>") directly — no ceremony. The server auto-resolves:
The path as-given (if it's a valid absolute host path it just works)
$PII_WORK_DIR/<basename> if that env is set
BFS (depth 4) of ~/Downloads, ~/Documents, ~/Desktop, $PII_WORK_DIR for an unambiguous match
If the response is status: "error" with a "file not found" or "ambiguous filename" hint — the file is in a non-standard location. Fall back to:
# create a marker next to the target file
touch "/path/visible/to/you/.pii_marker_abc"
# then:
resolve_path(filename: "<basename>", marker: ".pii_marker_abc")
# take host_path from the response and retry:
anonymize_file(file_path: "<host_path>")
The marker+resolve_path tools stay available as a reliability net — the auto-BFS handles ~95% of cases, marker covers the rest.
output_path, session_id, output_dir, docx_output_path (same as anonymize_file)
resolve_path
filename, marker
absolute path + parent dir (fallback when auto-BFS in anonymize_file can't find the file — user-drops-marker-next-to-file ritual)
deanonymize_text
text, session_id, output_path
File path only (takes anonymized text, writes deanonymized file)
deanonymize_docx
file_path, session_id?
File path only. If session_id is omitted, server reads pii_shield.session_id from the input .docx's docProps/custom.xml — works across chats/sessions without needing to pass session_id manually.
get_mapping
session_id
Placeholder keys + types only
list_entities
—
Server status and config
find_file
filename
Full host path(s) — searches configured work_dir only (fallback)
start_review
session_id
Opens the review panel in the chat (MCP Apps iframe). No URL, no browser.
apply_review_overrides
session_id, overrides
Called automatically by the review panel when the user clicks Approve. Claude does NOT call this directly.
apply_tracked_changes
file_path, changes (JSON), author
Output .docx with Word-native w:del/w:ins revision marks
export_session
session_id, passphrase, output_path
{archive_path, archive_size_bytes} — encrypted .pii-session archive for team handoff.
import_session
archive_path, passphrase, overwrite?
{session_id, overwritten, document_count, had_review} — restores a session's mapping locally after receiving an archive from a colleague.
DO NOT USE these tools (they exist on the server but must not be called for file workflows):
anonymize_text — sends raw text through the API. Only acceptable if user pasted text into chat.
scan_text — sends raw text through the API.
anonymize_docx — use anonymize_file instead (handles .docx automatically).
prefix parameter: Optional per-doc label WITHIN a shared session. Example: prefix="D1" prepends to placeholders as <D1_ORG_1>. Use it only when the user explicitly wants to visually distinguish placeholders from different documents inside the SAME matter (power-user case: "party A track" vs "party B track"). The default behaviour — no prefix — is recommended; identical entities across files in one session will coalesce into the same placeholder automatically.
session_id parameter (multi-file workflow): Pass the session_id from a previous anonymize_file call to ADD the new document to the same session. Identical entities across files in the session share the same placeholder (e.g. Acme Corp. becomes <ORG_1> in every file). The response includes the same session_id, a fresh doc_id, and pool_size (running count of unique entities). This is the default in ALL modes (MEMO, REDLINE, SUMMARY, COMPARISON, BULK, ANONYMIZE-ONLY) when the user uploads N≥2 files and confirms they're part of one matter — see references/bulk-mode.md "One matter" pipeline for the full step list. For unrelated files across separate matters, omit this parameter and use prefix="D{i}" instead.
review_session_id parameter: Pass the session_id from a previous anonymize_file call after HITL review. The server fetches the user's overrides internally and re-anonymizes. PII never passes through Claude.
Preferred approach: Always use anonymize_file(file_path) — only the file path (not content) passes through the API. The server auto-resolves paths via BFS of common user dirs, so passing a filename or the absolute path the user mentioned is fine. Fall back to resolve_path(filename, marker) or find_file(filename) only if the auto-resolve returns a not_found / ambiguous error.
Skip mode
If user says "skip pii shield", "don't anonymize", "work directly" — skip anonymization, work with the file directly.
Continuing in a later session (cross-chat deanonymize)
PII Shield v2.1+ embeds pii_shield.session_id into the docProps/custom.xml of every emitted _anonymized.docx. This makes the file self-describing: the server can recover the session_id without Claude holding it in context. If the session has multiple documents (a "one matter" multi-file session), EVERY file in the session carries the SAME session_id in custom.xml, and the shared mapping covers all of them — deanonymize_docx on any one file restores every placeholder in it from that matter's pool.
When the user returns in a new chat with an anonymized document and asks to restore PII (e.g. "deanonymize this", "give me the PII version", "restore my memo"):
Ask for (or accept) the file: .docx files carry their session_id internally. .txt/.pdf files don't — for those, the user must either pass the session_id or show you a parent anonymized .docx.
Call deanonymize_docx(file_path: "<path>") — no session_id argument needed for .docx with embedded metadata.
Server reads docProps/custom.xml → finds session_id → loads mapping from ~/.pii-shield/mappings/ → returns restored_path.
If response contains "session_id_source": "custom_xml" — tell the user the file was self-identifying (bonus clarity).
If response is an error like Mapping not found for session 'X', the mapping was cleaned up (TTL, or it was created on another machine). Ask the user if they have a .pii-session archive to import (team-handoff case).
ABSOLUTE BAN #2 still applies: NEVER read the restored file.
For .txt / .pdf and for files where the user overwrote custom.xml: ask the user to pass session_id explicitly via AskUserQuestion, or show list_entities (which lists recent sessions) and let them pick.
Team handoff (export / import encrypted session)
When one lawyer anonymized a document and a colleague needs to restore PII on their machine, the mapping itself must cross the trust boundary. PII Shield v2.1 ships this via an AES-256-GCM + scrypt encrypted archive — no network, no cloud.
Exporter side — "передай коллеге" / "export for X"
When the user asks to export a session for a colleague:
Make sure you know the session_id to export. If it's the current session, use it; otherwise call list_entities to see recent sessions and confirm with the user.
Ask the user for a passphrase via AskUserQuestion (or let them paste one). Minimum 4 characters; in practice 16+ with words is safer. Do not suggest a passphrase yourself.
Pick an output_path: by default <source_dir>/<matter-label>.pii-session. Absolute paths work best.
Show the user the archive path AND tell them verbatim:
"Send the colleague TWO things via different channels:
(1) the .pii-session archive (any file channel — email, Signal, SharePoint),
(2) the passphrase (a separate channel — phone call, password manager share).
Never send both in the same message. The archive is authenticated-encrypted; a wrong passphrase fails the decrypt loudly.
Also send the anonymized documents the colleague needs to restore — those are separate from the archive."
Do NOT echo the passphrase in your reply. If the user already typed it in chat that's their choice; you don't repeat it.
Importer side — "восстанови от коллеги" / "import from X"
When the user receives an archive and asks to use it:
Confirm you have both: the .pii-session archive path and the passphrase.
Call import_session(archive_path, passphrase). If the response is error: Session 'X' already exists locally, the same session_id already sits in the user's mapping store — ask the user whether to overwrite (true will replace the local copy with the imported one).
On success you get session_id. Now deanonymize_docx(<colleague's anonymized file path>) works — the file's custom.xml already names the session_id and the mapping is local.
If the user provides a wrong passphrase, the response error message says so literally — show it to the user, ask for the correct passphrase, retry.
Reference files — read BEFORE starting the mode
Load the appropriate reference file(s) based on the detected mode. Reference files are in the references/ directory next to this SKILL.md.
Mode / Phase
Read BEFORE starting work
All modes
references/hitl-review.md (at the HITL Review step)
references/bulk-mode.md + reference file(s) for the wrapped mode
ANONYMIZE-ONLY
No reference files needed
You MUST read the listed reference file(s) BEFORE starting analysis, not after.
Human-in-the-Loop Review (mandatory)
HITL review is mandatory after every anonymize_file call, unless the user has set skip_review: true in extension settings (Settings → Extensions → PII Shield). Check the PII_SKIP_REVIEW environment variable — if it equals "true", skip the review step entirely.
When review is active (default), first explain what will happen, then call start_review(session_id). The response opens an in-chat review panel (an MCP Apps iframe) with color-coded PII highlights. The panel runs entirely on the user's machine — no browser, no external server, no PII over the network.
Tell the user BEFORE calling start_review:
"I've anonymized N entities in your document. I'm opening a review panel right here in the chat. You'll see color-coded highlights: click any to remove false positives, select text to add missed entities. Click Approve in the panel when done, then send me any short message (e.g. 'done', 'continue') to proceed."
How approval reaches Claude — unconditional re-anonymize pattern
Do NOT use AskUserQuestion after start_review. Do NOT inspect the transcript for apply_review_overrides — that tool call is invisible to Claude on some hosts (known limitation). The server is the authoritative source of approval state.
Flow:
After start_review(session_id), reply with the "send any short message" prompt above, then STOP and wait for the user's next turn.
On the user's next message (whatever it is), call anonymize_file(file_path: "<original_path>", review_session_id: session_id)unconditionally. The server returns one of three statuses:
Response status
What it means
Action
waiting_for_approval
User hasn't clicked Approve yet.
Reply: "Still waiting for Approve click. Please click it in the panel and send any short message." Wait for next turn, retry this tool.
approved_no_changes
User approved without edits. Response includes original output_path / docx_output_path / output_rel_path / docx_output_rel_path.
Use these paths (same as originals). Proceed with pipeline.
success
User approved with edits (removed false positives and/or added missed entities). Response includes NEW output_path / docx_output_path / output_rel_path / docx_output_rel_path (with _corrected suffix).
REPLACEsession_id, output_path, output_rel_path, docx_output_path, docx_output_rel_path with the new values. Old files are stale — never read them.
This single unconditional call covers all three outcomes, skipping the ceremony of AskUserQuestion + transcript-inspection entirely.
Reading output files: always use output_rel_path (relative to the original input file's directory) joined with the input directory you passed — e.g. Read("<input_dir>/<output_rel_path>"). This works regardless of whether the caller's environment can access the absolute host path directly.
MODE DETECTION
Detect the mode from the user's request. If ambiguous, ask.
Multi-file clarification (triggered by FILE COUNT ≥ 2, not content)
Whenever the user uploads 2 or more files for ANY mode (MEMO, REDLINE, SUMMARY, COMPARISON, BULK, ANONYMIZE-ONLY), BEFORE calling the first anonymize_file ask ONE AskUserQuestion:
I see N files. Are they part of one matter (e.g. MSA + Amendment + SOW, same parties across files) or separate matters (e.g. unrelated NDAs from different clients)?
One matter (Recommended) → chain session_id across all files. Identical entities share placeholders. One review panel with N tabs. One deanonymize call. See references/bulk-mode.md "One matter" pipeline.
Separate matters → each file gets its own session with prefix="D{i}". Placeholders don't coalesce across files. See references/bulk-mode.md "Separate matters" pipeline.
The question is based strictly on file count, never on peeking at file contents (ABSOLUTE BAN #1). If the user has already stated intent in the conversation ("compare these two unrelated NDAs", "merge these three amendments"), skip the question and pick the matching pipeline.
For N = 1 file this question does not apply — go straight into the mode's single-file pipeline.
MODE: MEMO (Legal Analysis)
Full legal memorandum with risk assessment. The default mode. Read references/memo-writing-style.md + references/docx-formatting.md before starting.
Pipeline
Warm-up (if not already done in YOUR FIRST ACTION): list_entities() → verify ner_ready: true. If ner_ready: false, follow the Startup procedure loop above (poll list_entities every ~20 s, print each user_message verbatim) before proceeding.
Call anonymize_file(file_path: "<path or filename>"). Remember session_id, output_path, output_rel_path, output_dir. DO NOT Read any output file yet. Files are SEALED until HITL approves. If response is status: "error" with "file not found" hint, fall back to resolve_path + marker per "File path resolution" above, then retry.
Call start_review(session_id) — opens the in-chat review panel. Tell the user verbatim: "Review panel opened. Click Approve in the panel when done, then send me any short message (e.g. 'done') to continue." Then STOP and wait for user's next message.
On the user's next message, call anonymize_file(file_path: "<same path>", review_session_id: session_id)unconditionally (no AskUserQuestion, no transcript inspection — the server is authoritative). Handle the response:
status: "waiting_for_approval" → reply: "Still waiting for Approve click. Please click Approve in the panel and send any short message." Wait and retry on the next turn.
status: "approved_no_changes" → use output_path / output_rel_path from the response (equals the originals). Proceed.
status: "success" → REPLACE session_id, output_path, output_rel_path with the NEW values from the response. Old paths are stale.
Only now Read the anonymized text: use output_rel_path joined with the original input file's directory (e.g. Read("<input_dir>/<output_rel_path>")). This works regardless of environment. output_path (absolute host path) is a fallback if you happen to have direct host access.
Analyze anonymized text → structured memo with <ORG_1> etc.

All files are SEALED until HITL approves. If response is status: "error" with "file not found", use resolve_path + marker fallback.
Call start_review(session_id) — opens the in-chat review panel. Tell the user verbatim: "Review panel opened. Click Approve in the panel when done, then send me any short message (e.g. 'done') to continue." Then STOP and wait for user's next message.
On user's next message, call anonymize_file(file_path: "<same path>", review_session_id: session_id)unconditionally. Handle:
status: "waiting_for_approval" → ask user to click Approve, wait, retry next turn.
status: "approved_no_changes" → use original output_path / docx_output_path / rel_paths from response. Proceed.
status: "success" → REPLACE session_id, output_path, output_rel_path, docx_output_path, docx_output_rel_path with the NEW values.
Only now Read the anonymized text via <input_dir>/<output_rel_path>.
Analyze: identify clauses to change, draft new wording (all in placeholders).
Apply tracked changes to the anonymized .docx (use <input_dir>/<docx_output_rel_path>) via OOXML (see references/redline-tracked-changes.md). Save in output_dir.

MODE: COMPARISON (Diff Two Documents)
Read references/comparison-mode.md + references/docx-formatting.md before starting. Full pipeline is in the reference file. HITL gate (ABSOLUTE BAN #1) applies to every anonymize_file call in this mode — never Read any output_path before its session_id is approved.
MODE: BULK (Multiple Files)
Read references/bulk-mode.md + reference file(s) for the wrapped mode before starting. Full pipeline is in the reference file. HITL gate (ABSOLUTE BAN #1) applies to every anonymize_file call in this mode. Each file gets its own session_id and its own review panel. Wait for every session to receive apply_review_overrides before reading any output file.
MODE: ANONYMIZE-ONLY
Just anonymize and return the anonymized file(s). No analysis. No reference files needed.
Pipeline (single file)
Warm-up (if not already done in YOUR FIRST ACTION): list_entities() → verify ner_ready: true.
Call anonymize_file(file_path: "<path or filename>"). Remember session_id, output_path, output_rel_path, output_dir. DO NOT Read the output. In ANONYMIZE-ONLY mode, Claude NEVER reads the file — user is the only one who sees anonymized content. If "file not found" → fall back to resolve_path + marker.
Call start_review(session_id). Tell user: "Review panel opened. Click Approve, then send me any short message (e.g. 'done') to continue." Stop and wait.
On user's next message, call anonymize_file(file_path: "<same path>", review_session_id: session_id) unconditionally. Handle the 3 statuses (waiting_for_approval → ask user to click Approve and retry; approved_no_changes → use originals; success → REPLACE all values). Still DO NOT Read the output.
Present the anonymized file link (output_path and/or <input_dir>/<output_rel_path>) to the user and tell them the session_id in case they need deanonymization later. Tell them the anonymized .docx carries session_id in its metadata — they can return in a new chat with just the file and you'll be able to restore PII.
Pipeline (multiple files → one shared session)
When the user uploads multiple files and says "just anonymize them" (no analysis requested), group them into one session so identical entities across files share placeholders. This is the v2.1 way; don't fall back to the legacy D1/D2 prefix pattern for this case.
First file: anonymize_file(file_path: "<path_1>") — note the returned session_id (call it S).
Remaining files: for each file i in 2..N call anonymize_file(file_path: "<path_i>", session_id: S). Each response returns the same session_id, a new doc_id, and a growing pool_size. All N emitted .docx carry session_id=S in their docProps/custom.xml.
Call start_review(session_id: S) once. The panel shows all entities across all N docs (they're a single session now). Tell the user: "Review panel opened. Click Approve, then send any short message to continue."
On user's next message, call anonymize_file(file_path: "<path_i>", review_session_id: S) for each path i in 1..N, unconditionally, and handle the 3 statuses per file (same logic as single-file step 4). If ANY returned waiting_for_approval, ask user to approve and retry those paths next turn.
Present all N anonymized file links to the user. State the session_id ONCE and explain: "Одинаковые стороны во всех файлах помечены одинаково. Когда понадобится расшифровать — верните любой из этих файлов (или ваш memo на их основе) в новом чате и вызовите deanonymize_docx — сессия определится автоматически по метаданным docx."
The same pattern (chain session_id) is also the default in BULK-wrapped modes (MEMO, REDLINE, SUMMARY, COMPARISON when N≥2 files). See references/bulk-mode.md for the full pipeline and for the N≥2 clarifying question (one matter vs separate matters) that the skill must ask before the first anonymize_file call.
