At a glance
A skill your agent uses when you need to explain why your solution works and others failed.
- Works in 3 steps: Identify → Define mechanism → Name it
- You need to explain why your solution works and others failed
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
- Unique mechanism
What it does
Mechanism Builder is an agent skill from realkimbarrett/advertising-skills. Use when you need to explain why your solution works and others failed. Trigger on "unique mechanism", "why this works", "different angle", "positioning".
Its SKILL.md is about 170 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/mechanism-patterns.md`).
It sits in Marketing & SEO. The repository describes itself as: Advertising Skills for Open Claw, Claude Code & AI agents. Direct response, paid ads, funnels, and copy systems. The licence is MIT.
When your agent uses it
- You need to explain why your solution works and others failed
- Unique mechanism
- Different angle
Example prompts
- “unique mechanism”
- “why this works”
- “different angle”
- “/mechanism-builder”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Identify
- Define mechanism
- Name it
What it can do on your machine
Read from SKILL.md and the folder at commit 45f4a4a. 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
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.
Network
No URLs in SKILL.md.
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
Mechanism Builder loads about 167 tokens when it runs, and up to ~551 if it reads all its reference files. Until then it costs about 43 tokens; SKILL.md has 59 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.
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); files beside SKILL.md are not scanned.
