kocoroInspect AND manage Kocoro platform state — agents, skills, MCP servers, schedules, permissions, config, rules.
Kocoro is an agent skill from Kocoro-lab/Kocoro. Inspect AND manage Kocoro platform state — agents, skills, MCP servers, schedules, permissions, config, rules. 中:列出/查看/查询/创建/修改/删除/配置/安装 agent/skill/MCP/计划/权限/规则。 日:一覧/表示/確認/検索/作成/更新/削除/設定/インストール エージェント/スキル/MCPサーバー/スケジュール/権限/ルール。 Use for explicit operations on Kocoro-managed platform state under ~/.shannon/, including configured agents, skills, MCP servers, schedules, permissions, rules, and config. Route only that platform-state portion through the daemon API; mixed requests may and should continue with file…
Its SKILL.md is about 2.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 21 other files, including reference files (for example `references/agents.md`, `references/auth.md` and `references/calendar.md`).
It sits in Agent Workflows, covering MCP servers. It works with Model Context Protocol. The repository describes itself as: A Mac-native AI agent with memory, local computer access, browser control, IM channels, and MCP-native integrations. Built on Shannon. The licence is MIT.
Read from SKILL.md and the folder at commit 2d5a221. 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.
Kocoro loads about 2.5k tokens when it runs, and up to ~72k if it reads all its reference files. Until then it costs about 176 tokens; SKILL.md has 1,028 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 noted patterns worth knowing about, such as sudo or a known installer.
` (values go to OS keychain, NEVER edit `.env` or agent config for skill keys — see `references/skills.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.

Kocoro-managed platform operations go through the daemon HTTP API at http://localhost:7533.
Use the http tool for those operations — with ONE exception: schedules use the native schedule_* tools (see "Create schedule" below). Never use bash/file_write/file_edit to manipulate Kocoro-managed state under ~/.shannon/ directly — the API handles validation, atomic writes, and audit logging that direct file access would bypass.
This routing rule is scoped. If a request also asks you to inspect a project file, run a command, search the web, or use an integration, use the corresponding tools for those parts. Activating this skill never means “HTTP only” for the whole run.
When discover_installable_skills is available and the current task needs a
capability that is not in the visible installed skills, call it first. Do not
guess a use_skill name, call /skills/downloadable or
/skills/install/{name}, or ask for installation permission in text. If
discovery returns a match, immediately call offer_skill_installation with the
returned catalog IDs; that tool shows the localized Desktop card and stops the
run so the user can choose.
The generic skill HTTP operations below are only for explicit platform administration, such as when the user asks to browse the catalog or directly install a named skill outside a capability-dependent task, and for consumers where the recommendation tools are not available. A user's consent reply to a task-time suggestion is not platform administration; use the card workflow.
Create an agent:
http POST http://localhost:7533/agents
body: {"display_name": "Agent Name", "prompt": "You are a ... assistant. You help users ..."}
# The slug is server-generated (agent-<6hex>) and returned in the response; clients send only display_name.List agents: http GET http://localhost:7533/agents
Update agent prompt: http PUT http://localhost:7533/agents/{name} body: {"prompt": "..."}
Delete agent: http DELETE http://localhost:7533/agents/{name}?confirm=true (explain consequences first)
Agent config (model, tools): http PUT http://localhost:7533/agents/{name}/config body: {"agent": {"model": "..."}, "tools": {"allow": [...]}}
List globally installed skills: http GET http://localhost:7533/skills
List skills enabled for a named agent: http GET http://localhost:7533/agents/{name} and inspect skills
List bundled skills available to install (explicit administration): http GET http://localhost:7533/skills/downloadable
The runtime skill reminder contains only the skills enabled for the current agent. It is not a platform-wide installation inventory, and another agent can have a different enabled set. Always query GET /skills before answering which skills are installed globally.
Install a named skill directly (explicit administration only, outside a capability-dependent task): http POST http://localhost:7533/skills/install/{name}
Attach skill to agent: http PUT http://localhost:7533/agents/{name}/skills/{skill}
Set skill API keys: http PUT http://localhost:7533/skills/{slug}/secrets body: {"KEY_NAME": "value"} (values go to OS keychain, NEVER edit .env or agent config for skill keys — see references/skills.md)
Update settings: http PATCH http://localhost:7533/config body: {"agent": {"temperature": 0.7}}, then http POST http://localhost:7533/config/reload and verify with GET /config
Create rule: http PUT http://localhost:7533/rules/{name} body: {"content": "..."}
Schedules use the native schedule_* tools — NOT http. This is the one resource that must be created/updated/removed with the local tools (schedule_create, schedule_list, schedule_update, schedule_remove, schedule_show). They run through the same validated, audited ScheduleManager as the API, AND they capture the originating agent, channel, and conversation context — which is exactly what lets a schedule created from an IM channel (Slack/Lark/Feishu/…) proactively deliver its results back to that thread. A schedule created via raw http POST /schedules loses all of that: it runs as the default agent and never broadcasts, so the user never hears back.
schedule_create { cron, prompt, description, [agent], [stateful], [broadcast] }stateful: true when the task must remember across runs (the prompt counts runs / "第几次", continues from last time, or tracks progress). Without it each run starts blank and such prompts break. Omit agent to schedule the current agent (don't pass agent: "" unless you really want the default agent).schedule_list · schedule_show {id, …} · schedule_update {id, …} · schedule_remove {id, …}Long markdown content — use body_from_file for raw-text endpoints. When uploading a long markdown file (instructions, rule body, etc.) to an endpoint that accepts raw text, send it with Content-Type: text/markdown and body_from_file. This avoids hand-escaping quotes / backslashes / newlines in inline JSON, which is the #1 source of 400 errors on these endpoints.
http PUT http://localhost:7533/instructions
headers: {"Content-Type": "text/markdown"}
body_from_file: ~/source.mdCurrently raw-text upload is supported on PUT /instructions only. For endpoints that still require a JSON wrapper (POST /agents prompt field, PUT /rules/{name} content field, etc.), inline body is the only option — keep those payloads short, or split a long prompt across an initial POST /agents (short prompt) followed by a separate PUT /agents/{name} to update the prompt later if the daemon grows raw-text support there.

Do NOT add X-Confirm or any header to bypass:
endpoint, api_key, permissions.denied_commands. Tell the user to edit ~/.shannon/config.yaml directly, then call POST /config/reload and verify the effective value with GET /config.
MCP servers: shells (sh, bash, zsh), wrapper commands (env, nohup, sudo), and eval flags (-c, -e, --eval) are blocked. Use actual server binaries, not shell wrappers.
publish_to_web extension allowlist (cloud.publish_allowed_extensions): additive only. Do not coach users to "just add .pem / .key / source code" to the allowlist to work around blocked uploads — the path/suffix denylist still applies and is intentionally not user-configurable. If a user wants to publish source code or configs, the right answer is "convert to .txt / .md first, after auditing for secrets".
CONFIRM first: delete any resource, add MCP server, widen permissions, set daemon.auto_approve (disables approval prompts for all tool calls).

Kocoro fits situations like: explicit operations on Kocoro-managed platform state under ~/.shannon/; including configured agents.
Run `npx skills add Kocoro-lab/Kocoro --skill kocoro -a claude-code`. Or copy the skill folder (internal/skills/bundled/skills/kocoro in Kocoro-lab/Kocoro) into .claude/skills/kocoro in your project. Claude Code loads it when a task matches its description.
Run `npx skills add Kocoro-lab/Kocoro --skill kocoro -a codex`. Or copy the skill folder (internal/skills/bundled/skills/kocoro in Kocoro-lab/Kocoro) into .agents/skills/kocoro 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 Kocoro-lab/Kocoro --skill kocoro -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/kocoro, .gemini/skills/kocoro, .github/skills/kocoro and .opencode/skills/kocoro in your project.
SKILL.md names no scripts, command-line tools or credentials: Kocoro 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 notes only (mentions a .env file), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.
Kocoro is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.5k tokens (SKILL.md is roughly 10k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 69k tokens, read only when the agent opens those files.
