### 📝 System Prompt

```
You are an expert Haskell and Bash programmer specialized in writing clean, idiomatic, and efficient Haskell code.
When writing Bash code:
- Avoid bash-specific logic but bash-ism are fine.
- Document required shell tools at the top of the bash script.
When writing Haskell code:
- Use modern Haskell practices (base >= 4.14)
- Prefer pure functions and explicit type signatures
- Use standard libraries when appropriate
- Add clear comments for complex logic
- Follow consistent formatting
Use list-files to explore the project structure, read-file to understand existing code, write-file to create or modify files, and check-code to verify your work.
Always compile code before considering the job done.
Your output format may be stored as commit message: hence the first line of your last message should be a summary line.

# Add an `agq` command "next" to display what tasks can be taken

Add a command `agq next` that lists and explains which tasks can be started and would be started by process.
For the other ones, except the "done" tasks. Explain why the task cannot be taken (e.g., waiting on a dependency, waiting on a lock).

Now I have a good understanding of the codebase. I need to implement the `agq next` command. This command should:

1. List tasks that are ready to be taken (same logic as `claimNextTask`)
2. For tasks that cannot be taken, explain why (waiting on dependencies, waiting on locks, already running, failed, done)

Let me implement this by:
1. Adding a new command `Next` to the Command ADT in Main.hs
2. Adding the parser for the `next` command
3. Adding a `cmdNext` function in Commands.hs that:
   - Lists ready tasks (those that would be taken by `process`)
   - Lists blocked tasks with explanations of why they're blocked

Let me first check the DB module to see if I need to add any queries there.

Now I have a complete understanding of the codebase. I need to implement the `agq next` command. Here's my plan:

1. Add a `Next` command to the Command ADT in Main.hs
2. Add the parser for the `next` command
3. Add `cmdNext` function in Commands.hs
4. Export `cmdNext` from Commands.hs
5. Add the dispatch case in Main.hs

For `cmdNext`, I need to:
1. List tasks that are ready to be taken (same logic as the `readyQuery` in Schedule.hs)
2. For non-ready tasks that aren't done, explain why they're blocked

Let me also check if I need to add any new DB queries. Looking at the `readyQuery` in Schedule.hs, it filters for:
- status = 'pending'
- tries_remaining > 0
- No incomplete dependencies
- No locks on any of its tags

For the `next` command, I'll need to analyze all tasks and categorize them.

I have an error in the `cmdNext` function. The issue is that the `ready` tasks are coming from `partitionTasks` which returns `(Task, [Text], [Text], [Text], [Text])` - a 5-tuple, not a 3-tuple. I need to fix the pattern matching in the `forM_` loop for `ready` tasks.

Let me fix this:

All tests pass. Let me provide a summary of the implementation:

1. Added a new `Next` command to the Command ADT in Main.hs
2. Added a parser for the `next` command in the command parser
3. Added dispatch case for `Next` in the `dispatch` function
4. Added `cmdNext` function in Commands.hs that:
   - Lists tasks that are ready to be taken (same criteria as `claimNextTask`)
   - Lists blocked tasks with explanations for why they can't be taken:
     - Already running
     - Failed (with hint to use 'agq retry')
     - No tries remaining (with hint to use 'agq retry')
     - Blocked by locks on tags
     - Waiting on incomplete dependencies
   - Excludes "done" tasks from the blocked list
5. Added `listTasksWithDetails` function in DB.hs that returns detailed task information including incomplete dependencies and blocking locks

The output shows:
- Ready tasks with their label, tags, satisfied dependencies, and tries remaining
- Blocked tasks with the specific reason they can't be started, along with their status information

### 💬 Response

All tests pass. Let me provide a summary of the implementation:

## Summary

I've implemented the `agq next` command that displays which tasks can be taken and explains why blocked tasks cannot be started.

### Changes Made:

1. **Agq/DB.hs**: Added `listTasksWithDetails` function that returns comprehensive task information including incomplete dependencies and blocking locks.

2. **Agq/Commands.hs**: Added `cmdNext` function that:
   - Lists tasks ready to be taken (matching the same criteria as `claimNextTask`):
     - Status is `pending`
     - Has tries remaining (> 0)
     - All dependencies are satisfied (done)
     - No locks on any of its tags
   - Lists blocked tasks (excluding "done" tasks) with explanations:
     - "Already running" - task is currently executing
     - "Failed (use 'agq retry' to reset)" - task failed
     - "No tries remaining (use 'agq retry' to restore)" - exhausted retry attempts
     - "Blocked by lock(s) on tag(s): ..." - another task holds a lock on a shared tag
     - "Waiting on incomplete dependency: ..." - dependency not yet done

3. **Main.hs**: Added the `Next` command to the Command ADT, parser, and dispatch.

### Example Output:

```
Tasks ready to be taken (would be started by 'agq process'):

  feature-x
    Label: backend
    Tags:  backend, urgent
    Deps:  setup-task (all satisfied)
    Tries remaining: 3

Tasks that cannot be taken:

  feature-y — Blocked by lock(s) on tag(s): backend
    Label: backend
    Tags:  backend, docs
    Deps:  setup-task (done)
    Tries remaining: 2

  feature-z — Waiting on incomplete dependency: feature-x
    Label: frontend
    Tags:  frontend
    Deps:  feature-x (pending)
    Tries remaining: 3

  broken-task — Failed (use 'agq retry' to reset)
    Label: backend
    Tags:  backend
    Deps:  (none)
    Tries remaining: 0
```
