We have no content strategy yet, just a neglected blog. Can you build a 3-month content plan? I need target audience personas, 4-5 content pillars, a mix of blog posts, LinkedIn posts and a monthly email newsletter, plus keyword ideas and the KPIs I should track to show ROI. Budget is one part-time writer.” **example-2** “Please write an SEO-optimized blog post of about 1,000 words for our online plant shop. Target keyword: 'how to water succulents'. Audience is beginner plant owners who tend to overwater. Include a meta title and description, H2/H3 headings, a short FAQ section for featured snippets, and a soft call-to-action to our succulent starter kit. Tone should be friendly and practical. Then suggest 3 social posts to promote it.” ## Install Download the .zip and unzip it. Put `content-marketer.md` here: Claude Code · `~/.claude/agents/` · Every project. For one project only, use .claude/agents/ inside it. It gives the agent the tools it asks for, and no others. Cursor · `~/.cursor/agents/` · Cursor also reads the Claude Code folder above. It has no tools field, so it gives every agent every tool, whatever this one asks for. Codex · Codex’s custom agents are TOML files, not Markdown, so this agent doesn’t install there. Keep its license file beside it, as `content-marketer.LICENSE`: a name that doesn’t end in .md, since every .md file there is read as an agent. Then start a new session and ask for it by name. Folders checked 6 November 2026. Or [install from your agent](https://carteblanche.com/connect.md): ask it to install `content-marketer` from Carte Blanche. ## Badge for your README Carte Blanche: Verified Paste this into the agent’s README.

It says nothing about other models, and it doesn’t limit what your own agent can do. The answers were written without tools: the agent’s instructions were the system prompt, and it read no file and ran nothing. [How we test](https://carteblanche.com/how-it-works.md)
