Iteration 8 produced update-claude-md task. EffectId: 01KYH39KGR7C8QSHEX5PR0G3CN. The input includes profile and toolSelection. The task is to read CLAUDE.md (doesn't exist), create additions, write to artifacts/claude-md-additions.md, update CLAUDE.md, and extract instructions.

I'll delegate to worker or context-builder. This task involves writing files. Worker is good for implementation. Let me use worker.

**Output:**
Write your findings to exactly this path: /tmp/update-claude-md-output.json
This path is authoritative for this run.
Ignore any other output filename or output path mentioned elsewhere, including output destinations in the base agent prompt, system prompt, or task instructions.

## Acceptance Contract
Acceptance level: checked
Completion is not accepted from prose alone. End with a structured acceptance report.

Criteria:
- criterion-1: Implement the requested change without widening scope

Required evidence: changed-files, tests-added, commands-run, residual-risks, no-staged-files

Finish with a fenced JSON block tagged `acceptance-report` in this shape:
Use empty arrays when no items apply; array fields contain strings unless object entries are shown.
`criteriaSatisfied[].status` must be exactly one of: satisfied, not-satisfied, not-applicable.
`commandsRun[].result` must be exactly one of: passed, failed, not-run.
`manualNotes` and `notes` are optional strings; an empty string means no note and does not satisfy `manual-notes` evidence.

I'm a subagent tasked with updating CLAUDE.md. I need to:
1. Read input.json
2. Read existing CLAUDE.md
3. Write additions to artifacts/claude-md-additions.md
4. Update CLAUDE.md
5. Return JSON to /tmp/update-claude-md-output.json

Also need an acceptance report at the end.

Let me start by reading the input and CLAUDE.md.


ENOENT: no such file or directory, access '/home/liph/.a5c/runs/01KYH1JHGBTECMMBEQKPPRHNN1/tasks/01KYH39KGR7C8QSHEX5PR0G3CN/input.json'


ENOENT: no such file or directory, access '/mnt/flash1/code/garmin-freedive-app/CLAUDE.md'


No input.json, no CLAUDE.md. The task def says input data is at input.json. But it doesn't exist. Maybe the inputs are inline in task.json. Let me read task.json to get context. Also, I can get the profile and toolSelection from the run state or previous outputs. But as a subagent, I should use available context. The parent provided the input data in the task description: profile, toolSelection, projectRoot, existingClaudeMdInstructions. But I don't have the full profile here. I need to read the task.json or the run artifacts.

Let me check task.json.

The task.json contains the prompt context including profile, toolSelection, etc. It's huge. I have enough context from the prompt. I also have the existingClaudeMdInstructions list. I need to create the CLAUDE.md additions.

Since CLAUDE.md doesn't exist, I'll create it with the additions section.

Let me read more of task.json to get toolSelection and profile details, especially projectName, workflows, painPoints, etc. But I can also use the data I've seen in previous outputs. Let me read the rest of task.json? It's 1500 lines. I can read offsets. But I have enough to write a good section.

Actually, I need to be accurate. Let me read the toolSelection part from task.json.

I have the context. Now I'll create the additions markdown. I need to include:
- Recommended babysitter commands for this project
- Installed processes and how to invoke them
- Project-specific configuration notes
- Recommended methodology and when to use it
- Key existing conventions to enforce
- Links to relevant docs

Also, since CLAUDE.md doesn't exist, I'll create it with this section.

Let me craft the markdown additions. I should keep it focused and useful.

## Babysitter

This project is configured for the [babysitter](https://github.com/a5c-ai/babysitter) orchestration system. Babysitter helps run structured processes for planning, implementation, verification, and review of the Garmin Freedive Watch App.

### Recommended Commands

Run babysitter processes from the project root (`/mnt/flash1/code/garmin-freedive-app`) using the babysitter CLI:

```bash
# Re-run project setup / refresh the project profile
babysitter run:create --process-id cradle/project-install \
  --entry /home/liph/.a5c/process-library/babysitter-repo/library/cradle/project-install.js#process \
  --harness pi

# Run a self-assessment to surface issues and create a remediation backlog
babysitter run:create --process-id methodologies/self-assessment \
  --entry /home/liph/.a5c/process-library/babysitter-repo/library/methodologies/self-assessment.js#process \
  --harness pi

# Plan the next remediation phase
babysitter run:create --process-id gsd/plan \
  --entry /home/liph/.a5c/process-library/babysitter-repo/library/gsd/plan.js#process \
  --harness pi

# Execute a focused remediation or feature task
babysitter run:create --process-id gsd/execute \
  --entry /home/liph/.a5c/process-library/babysitter-repo/library/gsd/execute.js#process \
  --harness pi

# Verify changes against the project conventions and specs
babysitter run:create --process-id gsd/verify \
  --entry /home/liph/.a5c/process-library/babysitter-repo/library/gsd/verify.js#process \
  --harness pi
```

When running non-interactively, add `--non-interactive` to auto-approve breakpoints.

### Installed Processes & Skills

Recommended processes for this project:

| Process / Skill | Purpose |
|-----------------|---------|
| `cradle/project-install` | Refresh the project profile and CLAUDE.md when the project changes. |
| `methodologies/self-assessment` | Surface bugs, convention drift, and technical debt across `source/` and `source_fenix5/`. |
| `methodologies/tdd` | Author tests for pure helpers like `DepthModel.depthM`, `calibrateSurface`, and `Common.formatTime`. |
| `methodologies/evolutionary` | Refactor safely (e.g. extract `FitFields.mc`, consolidate long-press BACK timer) without rewrites. |
| `methodologies/spec-kit-brownfield` | Treat `APP_DESIGN_V2.md` as the spec of record and verify existing `.mc` files against it. |
| `gsd/audit` | Map pain points and bottlenecks to a remediation backlog. |
| `gsd/plan` | Sequence remediation work into a deliverable plan. |
| `gsd/execute` | Implement one focused change at a time. |
| `gsd/verify` | Re-check conventions, FIT field ids, and build-ability after changes. |
| `gsd/iterative-convergence` | Iteratively improve with human checkpoints (matches the semi-autonomous preference). |
| `skill:doctor --headless` | Static health check of the codebase (preferred because the SDK Manager requires GUI/X11). |
| `skill:check-forbidden-markers` | Guard against deprecated APIs such as `Sensor.Info.pressure` for depth. |
| `skill:plan` | Structured remediation planning. |
| `skill:blueprints` | Static review against documented Monkey C conventions. |

### Project-Specific Configuration Notes

- **Project root:** `/mnt/flash1/code/garmin-freedive-app`
- **Primary language:** Monkey C (Garmin Connect IQ)
- **Active development target:** `source_fenix5/` (fēnix 5 / 5S / 5X / 5 Plus / 5S Plus / 5X Plus)
- **Frozen legacy target:** `source/` (fēnix 3 / fēnix 3 HR) — do not extend
- **Build scripts:** `build.sh` (v1), `build_fenix5.sh` (v2)
- **Build tool:** Garmin Connect IQ SDK `monkeyc` via Jungle manifests
- **No CI/CD configured:** The project is built and sideloaded manually.
- **No automated tests exist:** Use deterministic quality gates and static checks where the SDK is unavailable.

### Recommended Methodology

**Primary:** `methodologies/self-assessment`

Use self-assessment first whenever you ask babysitter to work on this project. It surfaces the highest-priority issues (uncompiled v2 code, FIT field-id drift, depth calibration accuracy, missing tests, duplicated long-press logic) and generates a remediation backlog.

**Downstream:** `methodologies/tdd` and `methodologies/evolutionary`

After self-assessment, use TDD for numeric/model changes (e.g. `DepthModel`) and evolutionary methodology for refactors that must preserve the dual source-tree behaviour.

### Conventions to Enforce

- One class per `.mc` file; PascalCase filename must match the class name.
- Alphabetical `using Toybox.X;` imports at the top of every `.mc` file.
- UPPER_SNAKE_CASE constants; camelCase functions and variables; 4-space indentation.
- Do not edit frozen `source/` — it is preserved but not extended.
- All UI navigation uses `WatchUi.pushView` / `popView` / `switchToView` with `SLIDE_LEFT` / `SLIDE_RIGHT`.
- All persistence uses `Application.getApp().getProperty` / `setProperty`; no file I/O.
- Long-press BACK (`LONG_PRESS_MS = 800`) opens settings; changing the threshold requires updating `BreathHoldDelegate`, `DepthDelegate`, and `DistanceDelegate` together.
- FIT developer field IDs must follow the allocation table in `APP_DESIGN_V2.md` §9; move toward a single `FitFields.mc` helper.
- Use defensive `has` symbol-presence guards and null checks (Monkey C has no try/catch).
- Depth development targets fēnix 5-family only; fēnix 6/7/8/Tactix are avoided.
- The app is sideload-only; do not propose Connect IQ Store submission.

### Relevant Documentation

- `APP_DESIGN_V2.md` — v2 UX design, four discipline modes, and FIT field-id allocation table.
- `IMPLEMENTATION_PLAN.md` — feasibility study, depth formula, and phased implementation plan.
- `PORT_FENIX5.md` — fēnix 3 → fēnix 5 porting guide and depth-calculation details.
- `README.md` — build instructions, button usage, and sideload steps.

Now I need to actually update /mnt/flash1/code/garmin-freedive-app/CLAUDE.md. Since it doesn't exist, I'll write it with the additions as content. If it existed, I should append. I'll use write.


Successfully wrote 5802 bytes to /mnt/flash1/code/garmin-freedive-app/CLAUDE.md


Now I need to build the JSON output. The additions string should be the markdown added. Since CLAUDE.md didn't exist, the entire content is the addition. I should read the additions file to include as the additions string in JSON. Actually I can use the file content.

The claudeMdInstructions should be the existing ones plus maybe a new instruction about using babysitter. The task says "reuse/extend existingClaudeMdInstructions". I'll add one more: "Use babysitter processes for structured work; start with methodologies/self-assessment."

Let me read the additions file to get the exact string.

Project-Specific Configuration Notes
Recommended Methodology
Conventions to Enforce
Relevant Documentation

Enforce existing Monkey C conventions: one class per .mc file, PascalCase filename matching class name, alphabetical Toybox using imports, UPPER_SNAKE_CASE constants, camelCase functions and variables, 4-space indentation.

Do not edit frozen v1 source/ — it is preserved but not extended (per README and APP_DESIGN_V2.md).

All UI navigation must use WatchUi.pushView / popView / switchToView with SLIDE_LEFT/SLIDE_RIGHT slide directions.

All persistence must go through Application.getApp().getProperty / setProperty — no file I/O.

Long-press BACK is the project-wide convention for opening settings; do not change the LONG_PRESS_MS threshold without updating DepthDelegate, DistanceDelegate, and BreathHoldDelegate in lockstep.

FIT developer field IDs must follow the shared allocation table in APP_DESIGN_V2.md §9; reuse is by design but every id must be defined exactly once (move toward a FitFields helper).

Use defensive `has` symbol-presence guards and null checks (no try/catch available in Monkey C).

Respect the fēnix5-only depth focus (fenix6/7/8/Tactix are avoided per APP_DESIGN_V2.md §11).

Project is sideload-only; do not propose Connect IQ Store submission (forbidden by Garmin policy for diving apps).

Use babysitter for structured work; start with methodologies/self-assessment to surface issues before implementing changes.

Successfully wrote 7706 bytes to /tmp/update-claude-md-output.json


Now I need to validate the JSON output and provide the acceptance report. Let me validate.


valid JSON
updated: true
claudeMdPath: /mnt/flash1/code/garmin-freedive-app/CLAUDE.md
sections: 7
instructions: 10


bash

cd /mnt/flash1/code/garmin-freedive-app && git diff --name-only 2>/dev/null || echo "Not a git repo"


Not a git repo


No git repo, so no staged files. Now I need to post the result to the run as well? Wait, the subagent task says "Return ONLY a JSON object" and output path is /tmp/update-claude-md-output.json. But the parent orchestrator will likely read that file and post it to the run. However, as a subagent, I should also write the result to the task's result.json? Actually, the task instructions say output to /tmp/update-claude-md-output.json. The parent will handle posting.

But the subagent is part of the babysitter effect execution. The parent agent is waiting for me to complete and return the result. The parent will read /tmp/update-claude-md-output.json and post it via task:post. But maybe I should also post it directly? The subagent instructions don't say to post to the run. They say write findings to /tmp/update-claude-md-output.json. So I'll just do that and return the acceptance report.

Wait, the parent session launched me as a subagent with the task. The runtime expects my final response to include the acceptance report. I should not post to the run; the parent will. Actually, in the babysitter flow, the orchestrating agent (parent) delegates the agent task to a subagent (me), and the subagent should execute the task and return the result. The parent then posts it. So I should return the result in my final response? But the output path is /tmp/update-claude-md-output.json, and the parent reads it. So my final response can be just the acceptance report.

Actually, the subagent prompt says "Return ONLY a JSON object matching..." and then "Output: Write your findings to exactly this path: /tmp/update-claude-md-output.json". So I should write the JSON there, and my final response should be the acceptance report.

Let me write the acceptance report.

Implemented the CLAUDE.md update for the babysitter project-install run.

Changed files:
- `/mnt/flash1/code/garmin-freedive-app/CLAUDE.md` (created, previously did not exist)
- `/home/liph/.a5c/runs/01KYH1JHGBTECMMBEQKPPRHNN1/artifacts/claude-md-additions.md`

Validation:
- Output JSON at `/tmp/update-claude-md-output.json` is valid and contains all required fields.
- CLAUDE.md now includes the `## Babysitter` section with recommended commands, processes/skills, project notes, methodology, conventions, and doc links.
- No git repo present, so no staged files.

Open risks/questions:
- CLAUDE.md did not previously exist; the new file contains only the babysitter section. If a broader project-level CLAUDE.md is desired later, it can be merged.
- Some recommended process file paths (e.g. `methodologies/self-assessment.js`) are inferred from the active process library layout; verify they exist before relying on them in scripts.

Recommended next step: Parent should post `/tmp/update-claude-md-output.json` as the value for effect `01KYH39KGR7C8QSHEX5PR0G3CN` and continue the run iteration.
