+# Canonical call sequences
+
+## Push a file to a new branch, then open a PR
+
+```
+1. get_repository_tree or get_file_contents on the base branch — only needed if the
+   new file is actually replacing an existing one; skip for a brand-new path.
+
+2. create_or_update_file
+     owner, repo
+     path: "docs/example.md"
+     content: "<base64-encoded content>"
+     message: "docs: add example"
+     branch_name: "main"
+     new_branch_name: "feat/add-example"   ← branches off before the commit lands
+     (sha omitted — this is a new file)
+
+3. Hand off to gitea-prs to open a PR from "feat/add-example" into "main".
+```
+
+`new_branch_name` on `create_or_update_file` replaces a separate branch-creation call — the branch is created and the commit lands on it in one step.
+
+## Update a file when you don't already have its SHA
+
+SHA is mandatory for updates. If it wasn't captured earlier in the conversation:
+
+```
+1. get_file_contents
+     owner, repo
+     ref: "main"
+     path: "docs/example.md"
+   → read the top-level `sha` field (not content.sha)
+
+2. create_or_update_file
+     owner, repo
+     path: "docs/example.md"
+     content: "<new base64-encoded content>"
+     message: "docs: update example"
+     branch_name: "main"
+     sha: "<sha from step 1>"
+```
+
+Do not guess or omit the SHA — the write either fails (409 on create-path fallback) or is rejected outright.
+
+## Delete a file
+
+Same SHA-first pattern, no fallback path:
+
+```
+1. get_file_contents  owner, repo, ref: "main", path: "docs/old-example.md"
+   → read the top-level `sha` field
+
+2. delete_file
+     owner, repo
+     path: "docs/old-example.md"
+     message: "docs: remove old example"
+     branch_name: "main"
+     sha: "<sha from step 1>"
+```
