esper:fix

You are adding a fix to the esper backlog.

The user's initial prompt: $ARGUMENTS

Step 1: Check setup

Run esperkit config check. If it exits non-zero, tell the user to run /esper:init first and stop.

Read .esper/CONSTITUTION.md to understand the project's scope and principles.

Step 2: Interview the user

Use AskUserQuestion for a single focused round. Skip questions already answered by $ARGUMENTS:

• What is broken or incorrect? Describe the symptom and the expected behavior.
• Where in the codebase is the problem likely located? (file, module, component)
• Severity: blocking / urgent (p1), normal (p2), or low priority (p3)?
• How will we verify the fix works?

Step 3: Explore the codebase

Use the Task tool with subagent_type: "Explore":

Find the files and code paths relevant to [bug description].
Identify the likely root cause if visible from the code.
Do not include full file contents — return a concise summary of relevant files and patterns.

Cross-reference findings against .esper/CONSTITUTION.md to confirm the fix is in scope.

Step 4: Determine the next plan ID

Run esperkit plan next-id — this scans all plan directories (including archived/) and prints the next available zero-padded ID (e.g. 007).

Step 5: Write the plan file

Write .esper/plans/pending/NNN-slug.md where NNN is the next ID and slug is a short kebab-case name for the fix.

---
id: NNN
title: fix: [concise description of what's broken]
status: pending
type: fix
priority: [1 | 2 | 3]
phase: [current_phase from `esperkit config get current_phase`]
branch: fix/[kebab-slug]
created: [today YYYY-MM-DD]

# fix: [description]

## Context
[Root cause analysis from codebase exploration — what is actually wrong and why]

## Approach
[Step-by-step fix plan]

## Files to change
- [file path] (modify — [reason])

## Verification
- Run: [test command or manual steps]
- Expected: [what correct behavior looks like]
- Regression check: [related areas to verify haven't broken]

Step 6: GitHub Sub-Issue (if applicable)

Run esperkit config get backlog_mode. If the output is github:

esperkit plan create-sub-issue <filename>

This creates a GitHub issue for the fix and links it as a sub-issue of the phase's parent issue. The issue number is stored as gh_issue in the plan's frontmatter.

Step 7: Confirm

Tell the user:

• Fix plan created: .esper/plans/pending/NNN-slug.md
• Priority: p[N]
• Branch: fix/[slug] — this fix will get its own PR when shipped
• Next: /esper:apply to implement immediately, or /esper:backlog to queue it
