+# Milestones
+
+Use milestones to group related issues into a deliverable unit of work.
+
+Milestones can be read and managed through the GitHub REST API.
+
+## List Milestones
+
+```bash
+gh api "repos/{owner}/{repo}/milestones?state=all&per_page=100" \
+  --paginate \
+  --jq '.[] | {number, title, state, open_issues, closed_issues, due_on}'
+```
+
+## Get Milestone
+
+```bash
+gh api repos/{owner}/{repo}/milestones/{milestone_number}
+```
+
+## Create Milestone
+
+```bash
+gh api repos/{owner}/{repo}/milestones \
+  -X POST \
+  -f title="Milestone title" \
+  -f description="Milestone description"
+```
+
+Optional due date:
+
+```bash
+gh api repos/{owner}/{repo}/milestones \
+  -X POST \
+  -f title="Milestone title" \
+  -f description="Milestone description" \
+  -f due_on="2026-09-01T00:00:00Z"
+```
+
+## Update Milestone
+
+```bash
+gh api repos/{owner}/{repo}/milestones/{milestone_number} \
+  -X PATCH \
+  -f title="Updated title" \
+  -f description="Updated description"
+```
+
+## Close Milestone
+
+```bash
+gh api repos/{owner}/{repo}/milestones/{milestone_number} \
+  -X PATCH \
+  -f state=closed
+```
+
+## Reopen Milestone
+
+```bash
+gh api repos/{owner}/{repo}/milestones/{milestone_number} \
+  -X PATCH \
+  -f state=open
+```
+
+## List Issues in Milestone
+
+Use the milestone number, not the milestone title.
+
+```bash
+gh api "repos/{owner}/{repo}/issues?milestone={milestone_number}&state=all&per_page=100" \
+  --paginate \
+  --jq '.[] | select(.pull_request == null) | {number, title, state}'
+```
+
+The Issues REST endpoint can also return pull requests, so exclude entries
+containing `pull_request` when the caller specifically requests milestone issues.
+
+## Assign Issue to Milestone
+
+```bash
+gh api repos/{owner}/{repo}/issues/{issue_number} \
+  -X PATCH \
+  -F milestone={milestone_number}
+```
+
+## Remove Issue from Milestone
+
+```bash
+gh api repos/{owner}/{repo}/issues/{issue_number} \
+  -X PATCH \
+  -F milestone=null
+```
+
+## Delete Milestone
+
+Delete a milestone only when explicitly requested.
+
+```bash
+gh api repos/{owner}/{repo}/milestones/{milestone_number} \
+  -X DELETE
+```
+
+## Usage Rules
+
+- Use milestone numbers for API operations.
+- A milestone groups work; it does not define issue execution order.
+- Use native issue dependencies for execution ordering.
+- Do not infer dependencies merely because issues belong to the same milestone.
+- Listing a milestone for an automated workflow should include all open and
+  closed issues unless the caller explicitly requests otherwise.
