 Discover, analyze, and fix production issues using Sentry's full debugging capabilities.
 
+> **On-demand by default** — point it at a specific bug and it investigates and fixes it. It can *also* run unattended (see Autonomous Mode), but treat scheduled use as a secondary capability; for recurring queue hygiene reach for `sentry-triage-issues` or `sentry-groom-issues` instead. Opening a PR needs a clean working tree and `gh` auth.
+
 ## Invoke This Skill When
 
 - User asks to "fix Sentry issues" or "resolve Sentry errors"
 - User wants to "debug production bugs" or "investigate exceptions"
 - User mentions issue IDs, error messages, or asks about recent failures
-- User wants to triage or work through their Sentry backlog
+- User wants to write a code fix for a specific bug and (optionally) open a PR for it
+- A scheduled routine invokes the skill to auto-fix one issue unattended
+
+For *bulk backlog hygiene* — closing stale issues or re-opening regressions without writing code — use `sentry-groom-issues` instead.
 
 ## Prerequisites
 
 - Sentry MCP server configured and connected
 - Access to the Sentry project/organization
+- For opening a pull request (Phase 7): `gh` CLI authenticated (`gh auth status`) and a clean working tree
+- The fix and draft PR work on any MCP connection. Assigning the issue back in Sentry (Phase 7) additionally needs **issue-write enabled**; on a read-only connection that step is skipped and noted, and the PR is unaffected.
+
+## Autonomous Mode
+
+The primary, default mode is **interactive**: a human points the skill at a bug and stays in the loop. Autonomous mode is a secondary capability — when invoked from a scheduled routine or cron job (rather than an interactive request), run end-to-end without prompting:
+
+- **Do not** ask the user which issue to fix. Score candidates (Phase 1) and auto-select the single best one.
+- Fix exactly **one** issue per run, open a **draft** PR, and stop.
+- Skip every confirmation step; if a precondition fails (dirty tree, no `gh` auth, no qualifying issue), exit cleanly with the parseable summary in Phase 8 instead of asking.
+- Never widen the selection criteria to force a match. "Nothing qualified" is a valid, safe outcome.
+
+In interactive mode, keep the user in the loop: confirm the issue before fixing and the fix before opening a PR.

+### Scoring candidates for fixability
+
+Before committing to a fix — and always in autonomous mode — score each candidate so you spend effort where a fix is actually achievable in *this* repository:
+
+| Signal | Favors fixing | Counts against |
+|--------|---------------|----------------|
+| **Root cause location** | Stack frames point at files that exist in the current repo | Frames are all third-party / vendor / framework code |
+| **Bug class** | A concrete application-logic mistake (wrong key, off-by-one, missing null check on app data) | A broken environment (infra down, DNS, config, data corruption, OOM) — code is correct |
+| **Evidence** | Clear stack trace + reproducible data state | Vague message, no actionable stack trace |
+| **Scope** | Fix looks contained to one or two files | Requires cross-cutting or architectural change |
+
+Assign each candidate a fixability score (1–5) and a `fixable` boolean with one-line reasoning and suspected files. **Read enough of the actual code to judge — a surface read of the message and stack trace is not enough.** Many errors that look environmental (e.g. "file is not a database", "permission denied") turn out to be code bugs once you see how the failing code is called.
+
+**Selection:** pick the single issue that is `fixable`, scores **≥4**, and has at least one suspected file that exists locally (verify with `test -f`). If none qualify, report why each was skipped and stop — never lower the bar to force a match.

+When the fix lands as a PR (always in autonomous mode; in interactive mode, after the user approves the fix):
 
-Format:
+1. **Branch safety.** Work on a dedicated branch named `claude/sentry-fix-<issue-short-id-lowercased>`. Never commit the fix onto `main`/`master`. Before creating it, check whether the branch already exists (`git show-ref --verify --quiet refs/heads/<branch>`) — if it does, look for an existing PR (`gh pr list --head <branch> --state all`); skip the issue if a PR is already open, and stop with a clear message (never auto-delete) if the branch is orphaned.
+2. **Commit.** Make a single focused commit for the fix. Never use `git push --force` or `--no-verify`.
+3. **Open a draft PR** with `gh pr create --draft`. The body must include: a link to the Sentry issue, a short root-cause explanation, what changed and why, and the test plan (commands run + result).
+4. **Update Sentry, don't resolve.** Call `update_issue` to assign the issue to yourself (the authenticated user). **Never resolve the issue from this skill** — resolution happens when the PR merges. **If the MCP is read-only** (no `update_issue` tool available), skip this assignment and the marker in step 5, and note in the Phase 8 summary that the issue could not be assigned (read-only MCP). The draft PR itself is unaffected — it uses `gh`, not the MCP.
+5. **Record an agent-activity marker.** Leave a compact `sentry-agent-activity/v1` record so later automated runs and humans can audit what the agent did on this issue. Write it as an issue comment with a sentinel block `<!-- sentry-agent-activity:v1 {…} -->` if a comment tool is available, otherwise fold it into the `update_issue` reason. Skip if the MCP is read-only. Fields:
