sync-blocker-auditor

sync-blocker-auditor is a skill for Claude Code, Codex from pnp/sharepoint-skills. It costs 0 tokens per session (3,975 once invoked), scanned A, original, MIT.

A read-only checker for SharePoint document libraries that finds file names, folder names, and paths that can prevent OneDrive, File Explorer, or Teams from syncing. SharePoint is Microsoft’s shared document platform, and OneDrive is its file-synchronisation client.

In plain words
What is it for?
Checking naming and path restrictions, identifying checked-out files, scoring sync readiness, and producing an HTML report with safer proposed names. It does not modify the library.
Why use it?
SharePoint may accept content that later fails to sync, making errors appear gradually for individual users. The audit shows how widespread the problem is and ranks the issues by severity.

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

sync-blocker-auditor 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 9d 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.

How it starts

The opening of the file, as written. The whole thing — 253 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Sync Blocker Auditor

Purpose

SharePoint accepts file and folder names that the OneDrive sync client, File Explorer, and the Teams Files tab later refuse to handle. The result is the classic "we can't sync this file" error that surfaces one user at a time, long after the content was uploaded, with no way to see how widespread the problem is.

This skill audits a document library against Microsoft's documented naming and path restrictions, scores its sync readiness, and produces a severity-ranked HTML report with a proposed safe name for every blocked item.

It is strictly read-only: it never renames, moves, deletes, checks in, or modifies any item. The only thing it writes is the HTML report file.

Trigger Phrases

Activate this skill when the user says any of the following (or close variations):

  • "sync blockers" / "sync health check" / "sync readiness report"
  • "why won't this library sync" / "OneDrive sync errors" / "sync is failing"
  • "check file names" / "invalid file names" / "illegal characters" / "bad characters"
  • "path too long" / "url too long" / "400 character limit"
  • "files stuck checked out" / "who has files checked out"

Do not use this skill to actually rename or fix items. If the user asks for the fix to be applied, explain that this skill is read-only, hand them the rename plan from the report, and point them at a rename-capable skill or a bulk-rename tool.

Inputs & Scope

Determine the audit scope from the user's request and the current context, in this order:

  1. Selected items or folder — if the user has items selected or says "these/this folder", audit that subtree.
  2. Named library — if the user names one (e.g., "audit the Project Files library"), resolve it on the current site.
  3. Current library — if the user is in a library and gives no other scope, audit it recursively from its root.
  4. If no scope can be resolved, ask the user which library to audit. Do not guess.

Only audit content the current user can already see. Never invent items, paths, or values.
