Mode Classification is an agent skill from agentlas-ai/Agentlas-OS. Use before routing a /meta-agent request to choose single-agent-creator, team-builder, or agentlas-packager from the user's wording and available files.
Its SKILL.md is about 750 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 AI & LLM Engineering, covering Building AI agents. The repository describes itself as: Agent OS: keep specialist agents in a hub, spin up a temporary orchestrator per task. Local-first, works with any model. The licence is Apache-2.0.
9 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit cfdebf8. 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.
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.
Mode Classification loads about 745 tokens when it runs. Until then it costs about 43 tokens; SKILL.md has 359 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.

agentlas-packager.single-agent-creator. Two or more boundaries means a
team-builder candidate. If the boundary count is unclear, run the clarify
question loop before generating; do not infer from the word "team" alone.team-builder and require an
orchestrator/HQ plus memory, policy, eval, and QA. If the roles are
unrelated, create separate single-agent packages instead of one team.single-agent-creator may have many skills/tools but
must not emit multiple loose worker agent.md files. team-builder may be
small, but it must not omit the orchestrator/HQ.ontology-backed-agent overlay (modes/ontology-backed-agent.md) with
ontology_backed: true on the chosen base mode.loop_policy from task purpose and risk using
.agentlas/contract-injection-map.json risk tiers — none for simple
one-shot tasks, self-correct for complex or long-running work, verified
(separate-context verifier + side-effect gate) when the agent performs
external writes or sends. Do not force loops onto simple tasks.Return the selected mode, whether the ontology-backed-agent overlay applies,
the derived loop_policy, and one short reason. Then route to the matching
builder.

Mode Classification fits situations like: tasks that involve Building AI agents.
Run `npx skills add agentlas-ai/Agentlas-OS --skill mode-classification -a claude-code`. Or copy the skill folder (skills/mode-classification in agentlas-ai/Agentlas-OS) into .claude/skills/mode-classification in your project. Claude Code loads it when a task matches its description.
Run `npx skills add agentlas-ai/Agentlas-OS --skill mode-classification -a codex`. Or copy the skill folder (skills/mode-classification in agentlas-ai/Agentlas-OS) into .agents/skills/mode-classification 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 agentlas-ai/Agentlas-OS --skill mode-classification -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/mode-classification, .gemini/skills/mode-classification, .github/skills/mode-classification and .opencode/skills/mode-classification in your project.
SKILL.md names no scripts, command-line tools or credentials: Mode Classification 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.
Mode Classification is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 745 tokens (SKILL.md is roughly 3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
