[philbritton]

Summary

• add new rtk az command provider (src/az_cmd.rs) with compact output handlers for:
  • az pipelines list/show
  • az pipelines runs list/show
  • az account show/list
  • az group list/show
  • az resource list
  • az devops project list
  • az repos list/show, az repos pr list/show
  • az acr repository list/show-tags
  • az aks list/show
  • az webapp list/show
  • az monitor metrics list, az monitor activity-log list
  • az monitor app-insights component list/show, az monitor app-insights query
• wire command into CLI parsing and dispatch in src/main.rs
• add command rewrite/discovery support (az ... -> rtk az ...) in src/discover/rules.rs
• add rewrite/classification tests in src/discover/registry.rs
• update rtk init instruction templates and README docs to include rtk az

Testing

• C:\tools\rtk.exe test cargo +1.89 test az_cmd
• C:\tools\rtk.exe test cargo +1.89 test test_classify_az_pipelines_list
• C:\tools\rtk.exe test cargo +1.89 test test_rewrite_az_pipelines_list
• C:\tools\rtk.exe test cargo +1.89 test test_rewrite_az_monitor_activity_log_list
• C:\tools\rtk.exe test cargo +1.89 test test_try_parse_az_pipelines_list
• C:\tools\rtk.exe test cargo +1.89 test test_init_mentions_all_top_level_commands

Note: full cargo +1.89 test in this Windows environment reports one pre-existing failure in utils::tests::test_execute_command_success (unrelated to this change).

Hi! Two things needed before we can review:

1. Retarget to develop — this PR targets master, but all PRs should target develop. You can change the base branch in the PR settings (right sidebar).
2. Sign the CLA — if not already done, please sign at https://cla-assistant.io/rtk-ai/rtk

Thanks!

Hey

We are cleaning up the codebase and improving the project structure for better onboarding. As part of this effort, PR #826 reorganizes src/ from a flat layout into subfolders.

No logic changes — only file moves and import path updates.

What you need to do

Rebase your branch on develop when receiving this comment:

git fetch origin && git rebase origin/develop

Git detects renames automatically. If you get import conflicts, update the paths:

use crate::git;        // now: use crate::cmds::git::git;
use crate::tracking;   // now: use crate::core::tracking;
use crate::config;     // now: use crate::core::config;
use crate::init;       // now: use crate::hooks::init;
use crate::gain;       // now: use crate::analytics::gain;
