SkillSpector: 4 findings, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • high Agent Snooping · line 18
    Skill accesses MCP server configuration files (mcp.json). MCP configs contain server URLs, authentication tokens, and tool definitions — reading them allows the skill to discover and potentially abuse other tool integrations.
    Fix: Remove all code or instructions that read MCP configuration files (mcp.json). MCP server details should be managed by the agent runtime, not read by individual skills.
  • high Privilege Escalation · line 53
    Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
    Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.
  • medium Excessive Agency · line 132
    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
  • medium Rogue Agent · line 8
    Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
    Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

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

ofw 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 3d 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.

ofw-mcp

MCP server for OurFamilyWizard — provides read/write access to messages, calendar, expenses, and journal.

Setup

Option A — Claude Code (direct MCP, no mcporter)

Add to .mcp.json in your project or ~/.claude/mcp.json:

{
  "mcpServers": {
    "ofw": {
      "command": "npx",
      "args": ["-y", "ofw-mcp"],
      "env": {
        "OFW_USERNAME": "[email protected]",
        "OFW_PASSWORD": "yourpassword"
      }
    }
  }
}

Option B — mcporter

1. Install
npm install -g ofw-mcp

Or from source:

git clone https://github.com/chrischall/ofw-mcp
cd ofw-mcp
npm install && npm run build
2. Configure credentials
cp .env.example .env
# Edit .env: set OFW_USERNAME and OFW_PASSWORD
3. Register with mcporter
mcporter config add ofw \
  --command "ofw-mcp" \
  --env "[email protected]" \
  --env "OFW_PASSWORD=yourpassword" \
  --config ~/.mcporter/mcporter.json
4. Verify
mcporter list --config ~/.mcporter/mcporter.json
mcporter call ofw.ofw_get_profile --config ~/.mcporter/mcporter.json

Calling tools (mcporter)

mcporter call ofw.<tool_name> [key=value ...] --config ~/.mcporter/mcporter.json

Always pass --config ~/.mcporter/mcporter.json unless a local config/mcporter.json exists.

Tools

User

Tool Description
ofw_get_profile Current user + co-parent info (IDs, contact details)
ofw_get_notifications Dashboard summary: unread count, upcoming events, outstanding expenses. ⚠️ Updates last-seen status.

Messages

Tool Notes
ofw_sync_messages(folders?, deep?, fetchUnreadBodies?) Sync OFW → local cache. Call first if the cache might be stale. Returns unread inbox hints (bodies not fetched, to avoid mark-as-read).
ofw_list_message_folders List OFW folders with unread counts. Most reads use the cache; this is mainly for folder IDs and live unread counts.
ofw_list_messages(folderId?, since?, until?, q?, sort?, page?, size?, autoRefresh?, view?) Cache-backed list. Supports folder ("inbox"/"sent"/"both"), date range, and substring search. sort:"oldest" starts at the old end of a range instead of paging to it (default "newest"). Returns complete for the RESULT SET plus nextPage (null when done) — and the paging keys come FIRST in the JSON, before messages. returned carries the record count as a scalar, beside total. An empty result from a non-fresh cache is refused (UNVERIFIED_EMPTY) — pass autoRefresh:true to sync and answer instead.
ofw_get_message(messageId, allowMarkRead?, view?) Read a message OR draft body. Cache-first. Ids in the drafts cache return folder: "drafts". ⚠️ Falls through to OFW for unread inbox messages, which marks them read AND stamps a "First Viewed" time the co-parent can see — irreversible. Pass allowMarkRead:false to refuse that fetch instead; cached, sent and already-read messages are unaffected.
ofw_send_message(draftId?, subject?, body?, recipientIds?, replyToId?, expectedRevision?, deleteDraftOnSuccess?, myFileIDs?, force?) Send a message — the one irreversible operation. Preferred path: pass draftId (+ expectedRevision) to send an existing draft as it exists on the server — the tool re-reads it from OFW first and refuses if it changed since you read it (or was already sent/deleted); subject/body become optional overrides. recipientIds is usually still required: OFW does not store recipients on drafts. After a confirmed send the draft is auto-deleted (deleteDraftOnSuccess:false to keep it); on any failure or ambiguity it is retained and the response says why (draftRetained). Response leads with sentMessageId, draftKey, threaded, draftDeleted. Compose from scratch by passing subject/body/recipientIds with no draftId.
ofw_get_unread_sent(page?, size?, autoRefresh?) Sent messages your co-parent hasn't read yet (from cache). Leads with complete/hasMore/nextPage, then scanned/total, then unread; an empty sent cache that is not fresh is refused rather than reported as "nothing sent".
ofw_list_drafts(page?, size?, verify?, autoRefresh?, view?) Leads with complete/hasMore/nextPage; drafts comes last. List saved drafts, auto-verified: when the cache is not verified-fresh a cheap drafts sync runs first (default verify:true), so one call answers server-confirmed. verify:false serves straight from cache. Each draft carries serverConfirmed, revision and draftKey. Returns completecheck it before saying "you have N drafts". See Freshness.
ofw_save_draft(subject, body, recipientIds?, messageId?, replyToId?, myFileIDs?, expectedRevision?, force?) Create a new draft. Pass messageId to replace an existing draft: the tool creates a fresh draft and deletes the old one (OFW's update-in-place endpoint silently no-ops). The returned id is the NEW id; the response leads with draftKey, which stays the same across every edit — track that, not the id. Note: OFW does not store recipients on drafts — recipientIds are accepted but come back empty (a one-line NOTE says so; supply them at send time instead). Threading warnings fire only on genuine drops — a draft echoing inReplyTo/showContext IS threaded.
ofw_delete_draft(messageId) Delete a draft.
ofw_upload_attachment(path, shareClass?, label?, description?) Upload a local file to My Files; returns a fileId to pass into myFileIDs.
ofw_download_attachment(fileId, inline?, saveTo?, force?, extract?, maxChars?, parts?) Download an attachment. Inline delivery returns the first rung that works: image → ImageContent; .xlsx/.csv/.pdf/.docx/.pptx/text → extracted content under extracted (per-sheet CSV, per-page/slide text); anything else → raw bytes. Default writes to ~/Downloads/ofw-mcp/ (add extract:true for content too). Use parts:"1-2" / a sheet name and maxChars on large files.
ofw_check_freshness(folders?, messageIds?, allowMarkRead?) Cheap live check that the cache still matches OFW — one request for folder counts plus one per id, no bodies, no sync. Each id gets a live state (draft/sent/received/deleted/unknown) plus folder and sentAt. Probes ids cached as drafts, as sent, or as already-read inbox messages freely; anything else needs allowMarkRead:true (it would mark an inbox message read).
ofw_status(ids?, draftKeys?, includeDraftInventory?, allowMarkRead?) The status call. One live round trip. With no arguments: the full, server-verified draft inventory. With ids/draftKeys: each one's live lifecycle state. Top-level complete is true only when every part was verified live.
