Create a structured implementation plan for:

Follow this format:
1. **Goal** — one-sentence objective
2. **Constraints** — existing code, dependencies, tests, or assumptions to respect
3. **Approach** — high-level strategy and rationale
4. **Steps** — numbered, actionable tasks small enough to verify one at a time
5. **Verification** — how to confirm each step works (tests, logs, manual checks)
6. **Risks & Rollbacks** — what could go wrong and how to undo safely
7. **Open Questions** — anything that needs clarification before starting

Use the codebase context as needed. Do not write implementation code yet; only produce the plan.


The user wants a structured implementation plan but hasn't specified what the actual task is. They said "Create a structured implementation plan for:" but didn't complete the sentence with the actual feature/task. I need to ask for clarification. However, they also mentioned context-mode active. Since no specific task is provided, I should ask them what they want to implement. I cannot produce a meaningful plan without knowing the objective. I should ask a concise clarifying question.

What should the implementation plan be **for**? You left the topic blank after “Create a structured implementation plan for:”.

Please tell me the feature, refactor, fix, or integration you want planned, and I’ll use the codebase context to fill in Goal, Constraints, Approach, Steps, Verification, Risks & Rollbacks, and Open Questions.


Create a structured implementation plan for: can you create an app for freediving for the garmin venu 2. check the specs of the venu if the watch even support diving to lets say 50 meters. if not i also have a garmin fenix 3, would that work? the watch should be able to meassure my heart rate during the dive, dive time and distance in depth and or length, static breathhold function etc. check what it takes to create an app for the garmin and how i could upload that app onto my gamin either venu 2 or fenix 3. could maybe also puchase a cheap fenix 5 if needed.

The user wants me to create a structured implementation plan for a Garmin freediving app. They want me to check specs of Garmin Venu 2, Fenix 3, and possibly Fenix 5 to see if they support diving (water resistance, depth), heart rate monitoring underwater, dive time, distance/depth, static breathhold, etc. Also check what it takes to create a Garmin app and how to upload it.

I need to use web research for this since it's about Garmin specs and SDK info. I'll use web_explore to research:

1. Garmin Venu 2 water resistance / diving capabilities
2. Garmin Fenix 3 water resistance / diving capabilities
3. Garmin Fenix 5 water resistance / diving capabilities
4. Garmin Connect IQ SDK for creating freediving apps
5. Underwater heart rate monitoring on Garmin watches
6. Uploading/installing Connect IQ apps

I should use ctx_batch_execute or web_explore for research. Since these are web research questions requiring finding and comparing sources, web_explore is appropriate.

Actually, the instruction says "For web research questions that require finding and comparing sources, use web_explore. web_explore handles search, fetch, source ranking, and headless escalation internally."

I'll make several web_explore calls in parallel? I can use ctx_batch_execute for that, or just run web_explore multiple times. Let me use web_explore for comprehensive research. Maybe I can batch multiple web_explore questions into a single web_explore call? The tool takes a single query. But I could run multiple web_explore calls.

Actually, I can use ctx_batch_execute to parallelize multiple web_explore calls. But ctx_batch_execute executes shell commands. web_explore is a tool, not a shell command. So I should just call web_explore multiple times.

Wait, I can also use ctx_fetch_and_index to fetch specific pages. But first, let me do web_explore to get an overview.

Let me think about the plan structure:
1. Goal
2. Constraints
3. Approach
4. Steps
5. Verification
6. Risks & Rollbacks
7. Open Questions

I'll need to research technical facts about Garmin watches. Let me start with web research.

I’ll research the Garmin hardware specs, Connect IQ SDK capabilities, and app distribution requirements first, then write the plan.

Question: Garmin Venu 2 water resistance rating can it be used for diving depth meters

Question: Garmin Fenix 3 water resistance rating diving support depth

Question: Garmin Fenix 5 water resistance rating diving freediving depth sensor

Question: Garmin Connect IQ SDK create freediving app depth sensor heart rate underwater

The web_explore outputs are very terse - just "Reviewed X sources · synthesized answer with Y findings" but no actual content. This is odd. Maybe the output was hidden? Let me check if I need to call web_explore again or use a different approach.

I should use ctx_fetch_and_index to fetch specific Garmin pages. Let me find relevant URLs and fetch them. Actually, I can use ollama_web_search to get search results with snippets.

Let me use ollama_web_search for better results.
