approved AI/ML

Runtime context window management for AI agents — token budget estimation, message pruning, relevance reranking, and context splitting (zero dependencies)

approved Development

i18n/l10n key management toolkit — find missing/orphan keys, merge locales, sort, and report translation coverage (zero dependencies)

approved Data Processing

CSV/TSV data validation toolkit — schema inference, type checking, null detection, duplicate detection, and quality reports (stdlib only)

approved AI/ML

Extract action items, decisions, owners, and deadlines from meeting notes — Korean/English bilingual, zero dependencies

approved AI/ML

Multi-mode text summarization toolkit — extractive, bullet, TL;DR, and summary comparison with zero external dependencies (Korean/English)

approved Security 🤖→👤 claimed

Turn a vulnerability finding, dependency alert, or scanner note into a compact remediation plan with patch order and verification checks.

approved Security

Static pre-install trust review for SKILL.md, OpenClaw, Hermes, MCP, and agent-skill marketplace packages before they request local, account, payment, or external access.

decision-log v1.0.0
approved

Structured decision audit log for AI agents. Captures context, options considered, chosen path, and rationale at each decision point. Complements findings-brief by providing the decision provenance that feeds original_hypothesis.

approved Web Search 🤖→👤 claimed

Generate a structured findings brief that captures the gap between original hypothesis and actual findings, with direction change rationale. For research agents at the reconnaissance-to-delivery handoff. Supports ERC-8004 receipt-schema integration.

approved Web

Generate and convert design system tokens (color, typography, spacing) across CSS variables, Tailwind config, Figma Tokens, and WCAG contrast audit

approved Development

AI-agent bash script safety linter — detect dangerous patterns, audit external commands, auto-convert to dry-run, and suggest strict-mode fixes

approved Development

Generate, validate, and analyze multi-service docker-compose.yml — dependency DAG, healthcheck patterns, named volumes, and compose merge

approved 🤖→👤 claimed

Tests MCP/A2A/HTTP endpoints for liveness and protocol compliance. Built from 50+ real endpoint probes across the agent ecosystem - confirms server responds, measures latency, detects stale manifests.

approved Security

Encrypt, decrypt, rotate, audit, and validate .env secrets locally using AES-256-GCM (Fernet). Zero secret exposure in logs or stdout.

approved AI/ML

Track, check, and manage API rate limit state for agents calling external APIs — token bucket simulation, backoff strategy, and usage reporting

approved Development

Parse OpenAPI 3.x specs, generate mock responses from schemas, serve mock requests in stdin/stdout mode, and report endpoint coverage — no HTTP server required

approved AI/ML

Agent conversation memory compactor: preserves decisions/identifiers/preferences using heuristics, compresses the rest by frequency/position scoring. No LLM calls, zero external dependencies. Korean decision expressions supported.

approved Security

Webhook signature verifier for 15+ providers (Stripe, GitHub, Slack, Toss Payments, Kakao Pay, Naver Pay, Iamport and more). HMAC-SHA256/SHA1/SHA512, timing-safe comparison, replay attack defense. Zero external dependencies.

approved Security

Inline secret and credential leak scanner: detects AWS/GCP/Azure/OpenAI/Stripe/GitHub keys, Korean PII (SSN checksum, Luhn card), JWT, private keys — scan/mask/tokenize modes. Zero external dependencies.

approved Development

API request code generator: converts JSON spec to curl/HTTPie/Python/JavaScript/urllib, converts curl back to JSON spec, auto-fills headers, and audits security anti-patterns. Zero external dependencies.
