close-roundUse only after an arcgentic round has an external audit PASS and state.yaml is in passed.
Close Round is an agent skill from Arch1eSUN/Arcgentic. Use only after an arcgentic round has an external audit PASS and state.yaml is in passed. Anchors the verdict, runs strict audit-check, transitions passed to closed, and records the last passed round without writing an external audit verdict.
Its SKILL.md is about 390 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows. The repository describes itself as: Mechanical plan/dev/self-audit/external-audit gates for AI coding agents, with a configurable role-routing topology engine, an MCP-UI live status panel, and native-tooling Claude… The licence is MIT.
4 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 8539955. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Close Round loads about 391 tokens when it runs. Until then it costs about 64 tokens; SKILL.md has 130 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Categories
Use only after an arcgentic round has an external audit PASS and state.yaml is in passed. Close Round is an agent skill from Arch1eSUN/Arcgentic.yaml is in passed.
Close Round fits situations like: agent Workflows work in your project.
Run `npx skills add Arch1eSUN/Arcgentic --skill close-round -a claude-code`. Or copy the skill folder (skills/close-round in Arch1eSUN/Arcgentic) into .claude/skills/close-round in your project. Claude Code loads it when a task matches its description.
Run `npx skills add Arch1eSUN/Arcgentic --skill close-round -a codex`. Or copy the skill folder (skills/close-round in Arch1eSUN/Arcgentic) into .agents/skills/close-round in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Arch1eSUN/Arcgentic --skill close-round -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/close-round, .gemini/skills/close-round, .github/skills/close-round and .opencode/skills/close-round in your project.
SKILL.md names no scripts, command-line tools or credentials: Close Round is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Close Round is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 391 tokens (SKILL.md is roughly 1.6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Close Round: MCP Server Builder (anthropics/skills, 180k stars), Hook Development for Claude Code Plugins (anthropics/claude-plugins-official, 38k stars), Using Superpowers (farm-fe/farm, 5.6k stars) and Executing Plans Inline (obra/superpowers, 296k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
