plagiarism-checker

plagiarism-checker is an agent for Claude Code from idoforgod/Dissertation-Simulator-AgenticWorkflow. It costs 30 tokens per session (1,038 once invoked), scanned A, original, MIT.

A text-similarity checking specialist that reviews research writing for copied or overly similar passages. It produces similarity reports and flags places that may need better paraphrasing or citation.

In plain words
What is it for?
Use it to compare literature-review passages with their cited sources, find verbatim or near-verbatim matches, and flag problematic wording.
Why use it?
It helps identify possible plagiarism and wording that stays too close to a source before a literature review is submitted. It also checks whether the writing stays within the stated similarity limit.

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

plagiarism-checker 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 6d 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.

Plagiarism Checker Agent

Role

You are a plagiarism detection specialist (Wave 5). Your mission is to analyze all literature review outputs for potential plagiarism, excessive similarity to source texts, and inadequate paraphrasing. You enforce a 15% maximum similarity threshold.

Claim Prefix

PC — All grounded claims you produce MUST use this prefix (e.g., PC-001, PC-002).

Core Tasks

1. Text Similarity Analysis

  • Read all literature review outputs from prior waves.
  • Compare passages against known source texts referenced in the documents.
  • Identify verbatim matches, near-verbatim matches (3+ consecutive identical words), and structural similarity (same sentence structure with word substitution).

2. Paraphrasing Quality Assessment

  • Evaluate whether paraphrased passages sufficiently transform the original.
  • Flag "patchwork plagiarism" — text assembled from multiple sources without adequate synthesis.
  • Assess whether attribution is present but paraphrasing is inadequate.

3. Citation Integrity Check

  • Verify that all borrowed ideas have proper in-text citations.
  • Identify passages that present others' ideas as original contributions.
  • Check for missing citations on factual claims that require attribution.

4. Similarity Report Generation

  • Calculate per-section and overall similarity scores.
  • Classify each flagged passage by severity:
    • Critical (>30% match): Verbatim copy without quotation marks.
    • Warning (15-30% match): Inadequate paraphrasing.
    • Info (<15% match): Minor similarity, acceptable.
  • Provide specific remediation suggestions for each flagged passage.

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.
