Agent Review is an open-source skill for reviewing agent work, developed by Corey Gallon for Claude Code and Codex. It provides three cumulative review levels: Level 1 requires the agent to identify the expected artifact and verification check, then finish with an ARTIFACT-VERIFIED status and fingerprint or an ARTIFACT-MISSING explanation; Level 2 has two agents independently extract facts, uses a control total, and settles every difference against the original source; Level 3 adds a self-audit, adversarial cold reviewers with explicit reasons to challenge the work, and fresh reviewers who check the revised result. Claims are classified as measured, source-verified, inferred, or assumed, and findings and fixes are independently checked against the source. The skill is installed by cloning its repository into the Claude Code or Codex skills directory and is released under the MIT license.

NeuroArxiv is an agent skill that makes Claude Code or Codex CLI check arXiv prior art before proposing non-trivial architectures, algorithms, or systems techniques. It maps a problem to relevant arXiv categories, fetches papers over HTTP, reads sources independently to avoid cross-source anchoring, and converges them into a cited recommendation with a first implementation step and documented limitations or prior failures. The repository describes evaluations across physics, applied mathematics, quantitative biology, machine learning, and statistics, including checks for weaknesses in cited papers. It is distributed as a bundled skill that can be installed with npx without cloning or adding a build step.

SlopMonster is a Python linter for detecting formulaic or suspicious AI-generated writing in HTML pages, Markdown, plain text, landing pages, READMEs, emails, and scripts. Its scorer checks AI-associated vocabulary, sentence constructions, punctuation cadence, rule-of-three rhythms, and unsupported sales claims, assigns a score out of 5, and can fail a build when copy scores below 5/5. Its workflow scores the draft, performs a three-pass rewrite that removes suspect vocabulary and sentence shapes and replaces them with specific copy, sends the draft to a different model family for cleansing, and scores the result again. The cleansing script can use a Codex or Claude CLI, refuses to route a draft back to its own model family, and prints a prompt when no supported rival CLI is available. A GitHub Actions workflow is included as a reusable build gate; the scorer itself uses only Python's standard library, while the cleansing step requires an external AI CLI or manual prompt handling. The repository also includes regression tests, a catalogue of detection rules, rewrite principles, and worked before-and-after examples. It is distributed under the MIT license and can also be installed as an agent skill for Claude Code or used by other agents through its plain-Markdown instructions.

soundshuman is an open-source writing-analysis and repository-auditing toolkit for identifying patterns associated with AI-generated prose. It combines a humanizer skill, a machine-readable rule pack, and a zero-dependency CLI: the skill uses a 41-pattern catalog, statistical signals, voice calibration from writing samples, and a draft–audit–final workflow; the rule pack stores vocabulary tiers, phrase fixes, and weighted regular-expression detectors in JSON; and the CLI scores text from 0 to 100, explains findings with line numbers and triggered rules, applies selected mechanical fixes, scans repositories, and can gate CI. The project states that its goal is inspectable editing rather than defeating AI detectors, with rewrites delivered as reviewable Git diffs and a no-invented-facts rule. The CLI runs on Node 18 or later without dependencies and supports pasted text, files, repository audits, and directory scans. The skill is distributed as plain Markdown for agent harnesses and as a Claude Code plugin; the repository also includes reference materials, a pre-commit hook, CI integration, and installation instructions. It is MIT licensed, with upstream copyrights preserved in the license.
