Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00014 | $0.00333 |
| Opus 5.5 | $0.00006 | $0.00133 |
| Sonnet 5.5 | $0.00003 | $0.00067 |
| Haiku 4.5 | $0.00001 | $0.00033 |
Grade A, and why
agent-manager scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Agent Manager Skill
This skill exposes dedicated tools to manage persisted sub-agents in the current conversation.
Capabilities
spawn_agent: create a sub-agent for a task.send_input: continue an existing sub-agent with another user message.wait_agent: wait until one or more sub-agents complete.close_agent: stop and close a sub-agent.list_agents: inspect persisted sub-agent summaries.
Usage Guidelines
- These tools are only available to the main agent.
- Sub-agents are not allowed to spawn or manage other sub-agents.
- Agent records and transcripts are persisted in
ChatStorage(agentsandagent_messagestables). - Agent profiles in Settings can define reusable names, descriptions, system prompts, and selected skill scopes for session-level mentions.
- Mentioning a configured agent from the prompt toolbar injects that profile into the current run context; the same selected-skill scope is enforced by tool visibility and tool calls.
- Favorites always launch through the main agent. Agent profiles remain scoped to explicit mentions in the current conversation.
- Agent-management tools are not read-only and must not be invoked through
parallel_tools.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

agent-manager is a skill published in the GitHub repository chuancyzhang/deepseek-cowork (18 stars, last pushed today), licensed Apache-2.0. It adds 14 tokens to every session and 333 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-04.
