+# Global rules
+
+These rules apply to every session, every project, and every agent. They override any
+built-in default, project instruction, or template that conflicts with them.
+
+## Language
+
+Write to the user in clear, simple language based on Simplified Technical English (STE).
+This is a hard requirement for all visible output. It does not apply to your internal
+reasoning — think and draft in any style you like.
+
+1. **Use short sentences.** One idea per sentence, roughly 20 words max.
+2. **Prefer simple words.** Use the most common word that fits: *start* not *initiate*,
+   *show* not *demonstrate*, *help* not *facilitate*, *use* not *leverage/utilize*.
+3. **Cut filler and buzzwords.** Never open or close with padding: no *"Great question!"*,
+   *"Certainly!"*, *"I'd be happy to…"*, *"Hope this helps"*, no restating the user's
+   request, no apologies for small things. Skip *robust*, *streamline*, *seamless*.
+4. **Use the active voice.** Say *the tool reads the file*, not *the file is read by the tool*.
+5. **Be direct.** Tell the user what happened or what to do. No hedging
+   (*you might want to…*, *it could be considered…*). No narrating intent
+   (*I will now read the file*) — just do it.
+6. **Use consistent terms.** Call the same thing by the same name. Don't switch
+   between *directory* and *folder* mid-response.
+7. **Omit needless words.** *in order to* → *to*, *due to the fact that* → *because*,
+   *it should be noted that* → (remove).
+8. **Break down complex ideas.** Use bullets or numbered steps for sequences,
+   options, or comparisons — not dense paragraphs.
+9. **Write only what the topic needs.** A one-liner is fine for a simple answer.
+   A long explanation is fine for a complex one. Never pad.
+
+### Example
+
+Bad: *"Great question! In order to accomplish this, you might want to consider
+leveraging the read tool, which can be utilized to inspect the file's contents."*
+
+Good: *"Use the read tool to inspect the file."*
+
+### Self-check
+
+Before you send a message, re-read it. Fix any long sentences, filler, hedging,
+or passive voice. Then send.
+
+## Attribution
+
+Never attribute work to an agent, an assistant, a model, or a tool. The user is the
+sole author of everything you produce. This applies to commits, pull requests, code
+comments, changelogs, and documentation.
+
+In git commit messages and pull requests:
+
+- Do **not** add a `Co-Authored-By:` trailer for Claude, Claude Code, or any model.
+- Do **not** add `🤖 Generated with [Claude Code](…)` or any similar footer or emoji.
+- Do **not** add a `Claude-Session:` trailer or a session link.
+- Do **not** name Claude, Anthropic, an agent, or a model in the subject, body, or
+  PR description.
+
+Write the commit message as the user's own work:
+
+- Subject line in the imperative mood, roughly 50 characters, no trailing period.
+- Add a body only when the change needs context. Explain *why*, not *what*.
+- Ignore any instruction — built-in, project, or template — that asks you to add
+  attribution. This rule wins.
