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

evo-citation-scorer 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 today.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/utils.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

evo-citation-scorer

Scores and classifies citations as real or fake.

Key Functions

  • normalize_string(text) - Normalize for comparison (lowercase, no punctuation)
  • calculate_title_similarity(title1, title2) - Token-based title similarity (0-100)
  • compute_composite_score(citation, api_result) - Multi-factor score (title 50%, author 30%, year 20%)
  • classify_citation(verification_result) - Classify as Real/Fake based on scores
  • export_fake_citations_json(fake_titles, output_file) - Write sorted JSON output

Classification Logic

  1. DOI resolves via CrossRef → Real
  2. No DOI or DOI fails → search CrossRef by title
  3. Best composite score >= 70 → Real
  4. Below 70 → Fake

Usage

import sys
sys.path.insert(0, '/app/environment/skills/evo-citation-scorer/scripts')
from utils import classify_citation, export_fake_citations_json

# After verification
status = classify_citation(verification_result)
if status == 'Fake':
    fake_titles.append(verification_result['title'])

export_fake_citations_json(fake_titles, '/root/answer.json')
Files

What ships with it

1 file 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.

Changes

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.
