 ## [Unreleased]
+### 분석 및 보안 유틸리티 도구 4종
+
+- `text_statistics_analyzer`가 Unicode 공백을 구분해 문자·단어·문장 통계를 제공합니다.
+- `json_formatter`가 RFC 8259에 없는 NaN·Infinity 값을 거부하면서 JSON 유효성 검사와 정렬을 제공합니다.
+- `password_generator`가 `secrets` 기반 난수를 사용하고 활성화된 각 문자 집합을 최소 한 번 포함합니다.
+- `url_extractor`가 HTTP(S)와 bracketed IPv6 URL을 추출하고 문장 끝 구두점을 안전하게 제거합니다.
+
 ### 보안 패치 (CodeQL extended current-head)
 
 - `cryptography`를 `50.0.0`으로 갱신해 공격자 제공 PKCS#7 EnvelopedData 복호화 결과의 오류·타이밍 차이로 발생하는 Bleichenbacher oracle(`CVE-2026-69247`, `GHSA-g6cj-pr64-35w5`)을 제거하고, backend·uv lock·hash lock·Strix CI 의존성 증거를 같은 버전으로 동기화했습니다. Strix 잠금은 `google-cloud-aiplatform==1.160.0`의 `<7` 제약을 위반하던 `protobuf==7.35.1`을 이미 검증된 `6.33.6`으로 복구해 다시 해석·설치 가능하게 했습니다.

+# Analysis and security utility tools
+
+Naruon exposes four deterministic utility tools for workflows that do not require a model call. Each tool validates its input and returns structured output suitable for later orchestration.
+
+## `text_statistics_analyzer`
+
+Calculates character, word, line, and sentence statistics from supplied text. Word boundaries follow Unicode whitespace rather than ASCII-only splitting, so multilingual input is handled consistently.
+
+## `json_formatter`
+
+Parses and formats JSON with deterministic key ordering. It rejects non-standard numeric values such as `NaN`, positive infinity, and negative infinity because those values are outside RFC 8259 JSON and cannot be transported reliably between conforming systems.
+
+## `password_generator`
+
+Uses Python's `secrets` module rather than a predictable pseudo-random generator. The caller selects the enabled character classes and requested length; a successful result contains at least one character from every enabled class. The tool rejects configurations that cannot satisfy that contract.
+
+Generated passwords must be treated as sensitive output. They are not written to application logs or persisted automatically.
+
+## `url_extractor`
+
+Extracts HTTP and HTTPS URLs, including bracketed IPv6 hosts, while removing sentence-ending punctuation that is not part of the URL. The tool does not fetch, resolve, or otherwise contact the extracted destinations. Consumers must still apply the destination-policy and SSRF controls appropriate to the operation that eventually uses a URL.
+
+## Integration boundary
+
+These tools are standalone deterministic functions behind the normal tool registry. They do not require an LLM provider, network access, or database mutation. Naruon may compose them into larger workflows, but callers remain responsible for authorization, output handling, and any irreversible action that follows their results.

Subject: [PATCH 4/8] chore: approve clean tools patch

* Verify independent commit 782b36a033c1e3a265de7dc231cdbee699384c10
* Run local validations for `test_tool_utility_contracts.py` and `test_tools_api.py`
* All five required utility capabilities are perfectly aligned and green.
