Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00027 | $0.01864 |
| Opus 5 | $0.00014 | $0.00932 |
| Sonnet 5 | $0.00005 | $0.00373 |
| Haiku 4.5 | $0.00003 | $0.00186 |
Grade A, and why
false-positive-filter 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 8d 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 — 238 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Filter Rules
Pattern-Based Filters
| Category | Pattern | Action | Confidence |
|---|---|---|---|
| Sanitized Output | htmlspecialchars, e(), {{ }} |
Mark as FP (XSS) | 0.95 |
| Prepared Statement | ->where(), DB::select() with ? |
Mark as FP (SQLi) | 0.95 |
| Test Code | /tests/, /spec/, *Test.php |
Mark as FP (All) | 1.00 |
| Security Ignore | @security-ignore (with required attrs) |
Mark as FP (All) | 0.90 |
Note: /vendor/, /node_modules/ は除外対象外。sca-attackerで別途脆弱性検出。
@security-ignore Format
// @security-ignore reason="false positive - input from trusted source" reviewer="john"
| Attribute | Required | Description |
|---|---|---|
| reason | Yes | 除外理由（必須） |
| reviewer | Yes | レビュー承認者（必須） |
属性なしの@security-ignoreはconfidence 0.50（手動レビュー必須）
Context-Based Filters
| Category | Context Check | Action |
|---|---|---|
| Framework Auto-Escape | Blade {{ }}, Jinja2 default |
Mark as FP (XSS) |
| ORM Protection | Eloquent, Django ORM | Mark as FP (SQLi) |

Sanitization Patterns by Language
sanitization_patterns:
php:
xss:
- 'htmlspecialchars\s*\('
- 'htmlentities\s*\('
- 'strip_tags\s*\('
- '\{\{\s*\$' # Blade auto-escape
- 'e\s*\(' # Laravel helper
sql-injection:
- '->where\s*\([^,]+,\s*\?'
- '->whereRaw\s*\([^,]+,\s*\['
- 'DB::select\s*\([^,]+,\s*\['
python:
xss:
- 'escape\s*\('
- '\{\{[^|]*\}\}' # Jinja2 auto-escape
# Note: mark_safe は除外対象外（エスケープ無効化のため脆弱）
sql-injection:
- 'execute\s*\([^,]+,\s*\['
- 'execute\s*\([^,]+,\s*\('
- '\.filter\s*\(' # Django ORM
javascript:
xss:
- 'textContent\s*='
- 'encodeURIComponent\s*\('
- 'DOMPurify\.sanitize\s*\('
sql-injection:
- '\?\s*,' # Parameterized query
- '\$\d+' # Positional parameter
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.

false-positive-filter is an agent published in the GitHub repository morodomi/redteam-skills (2 stars, last pushed 6mo ago), licensed MIT. It adds 27 tokens to every session and 1,864 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
