What it does

Skill Manager is an agent skill from AFK-surf/OpenBridge. Manage skills: create, install, modify, or delete skills. Trigger when user asks to: "create a skill", "save this as a skill", "install this skill" (from URL/link), "edit/modify a skill", "delete a skill". User skills live under ~/.openbridge/skills/.

Its SKILL.md is about 750 tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including scripts and reference files (for example `references/create-from-conversation.md`, `references/install-from-npx-skills.md` and `references/install-from-url.md`).

It sits in Agent Workflows, covering Skill management and Skill authoring. The repository describes itself as: A free, safe and open agent for everything. Alternative to Claude Cowork & Codex. Open Bridge, the AI bridge between your intention and get the job done. The licence is MIT.

When your agent uses it

User asks to: create a skill
Save this as a skill
Install this skill (from URL/link)
Edit/modify a skill

Example prompts

“create a skill”
“save this as a skill”
“install this skill”
“/skill-manager”

Requirements

Python 3
Node.js

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

Locate the SKILL.md in ~/.openbridge/skills/ (check custom/ and imported/) or in a configured sync folder
Read current content
Apply changes as requested
Validate if possible
Report what was changed

What it can do on your machine

Read from SKILL.md and the folder at commit a9ca905. It shows what the files ask for, not the result of running them.

Tool permissions
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.
Runs code
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
- npx
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Skill Manager loads about 749 tokens when it runs, and up to ~4.8k if it reads all its reference files. Until then it costs about 66 tokens; SKILL.md has 293 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~66
When it runs · the whole SKILL.md, loaded when a task matches: ~749
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~4.8k

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.

Safety

Auto-check passed

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); the scripts in this folder are not scanned.

Skill Manager

This skill provides guidance for all skill-related operations: creating, installing, modifying, and deleting skills.

About Skills

Skills are modular, self-contained packages that extend the agent by providing specialized workflows and bundled resources. Think of them as an "onboarding guide" for a specific task category.

Skill Directories

User skills live under ~/.openbridge/skills/:

Directory	Purpose
`custom/`	User-created skills
`imported/`	Skills imported from the OpenBridge skill library

Synced local skills may also appear through configured sync folders. Those stay at their original locations and are not installed into ~/.openbridge/skills/.

IMPORTANT: When creating or installing managed local skills, always use ~/.openbridge/skills/custom/<skill-slug>/ unless the flow explicitly targets imported/.

Operation: Install Skill from URL

When the user provides a URL to a skill (e.g., https://example.com/dot_claude/skills/xxx/SKILL.md) and asks to "install this skill".

Read the detailed guide: references/install-from-url.md

Operation: Install Skill via npx skills CLI

When the user asks to install a skill using npx skills add.

Read the detailed guide: references/install-from-npx-skills.md

Operation: Create Skill from Current Conversation

Convert the current multi-turn chat solution into a reusable custom skill.

Read the detailed guide: references/create-from-conversation.md

Operation: Modify Existing Skill

When the user asks to modify, edit, or update an existing skill:

Locate the SKILL.md in ~/.openbridge/skills/ (check custom/ and imported/) or in a configured sync folder
Read current content
Apply changes as requested
Validate if possible
Report what was changed

Note: System skills are read-only. To customize behavior, create a new skill under ~/.openbridge/skills/custom/.

Operation: Delete Skill

When the user asks to delete or remove a skill:

Confirm location: Only ~/.openbridge/skills/custom/ or ~/.openbridge/skills/imported/ skills can be deleted
Confirm with user (list what will be removed)
Delete: rm -rf ~/.openbridge/skills/custom/<skill-slug>/
Report deletion

Cannot delete: system skills, synced skills (manage at original location)

Files

SKILL.md and 6 other files (scripts, references) in macos/OpenBridge/Resources/SystemSkills.bundle/skill-manager of AFK-surf/OpenBridge.
