A diagnostic command for checking whether an FTC robotics development setup and robot connection are ready to use.

Use `/doctor` to inspect the environment or `/doctor --fix` to attempt automatic fixes for detected issues.

It finds common setup problems with ADB, the Python runner uv, robot access, Gradle, and project files before they interrupt development.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00015	$0.01083
Opus 5.5	$0.00006	$0.00433
Sonnet 5.5	$0.00003	$0.00217
Haiku 4.5	$0.00002	$0.00108

Security

Grade D, and why

doctor scanned grade D with 3 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.

Doctor Command

Diagnoses your FTC development environment and helps fix issues.

Usage

/doctor          # Check environment
/doctor --fix    # Attempt automatic fixes

What It Checks

ADB Installation
- Is adb command available?
- What version is installed?
uv (Python runner)
- Is uv command available?
- Required for OpMode control and future plugins
Robot Reachability
- Can we ping the robot (192.168.43.1)?
- Is the robot's ADB port accessible?
Gradle Setup
- Does gradlew exist in the project?
- Is it executable?
Project Structure
- Is this an FTC project (has TeamCode)?
- Is local.properties configured?

Process

When this command runs:

Detect platform (macOS, Linux, Windows)
Check ADB:
```
command -v adb
adb version
```
If missing, show platform-specific install instructions:
- macOS: brew install android-platform-tools
- Linux: sudo apt install android-tools-adb
- Windows: Download from developer.android.com
Check uv:
```
command -v uv
uv --version
```
If missing, show platform-specific install instructions:
- macOS/Linux: curl -LsSf https://astral.sh/uv/install.sh | sh
- Windows: powershell -c "irm https://astral.sh/uv/install.ps1 | iex"

Check robot connection:

ping -c 1 -W 2 192.168.43.1
adb devices

Check Gradle:
```
ls -la gradlew
./gradlew --version
```
Check project:
- Look for TeamCode/ directory
- Check local.properties exists

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

doctor is a command published in the GitHub repository ncssm-robotics/ftc-claude (5 stars, last pushed 9mo ago), licensed MIT. It adds 15 tokens to every session and 1,083 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it D with 3 findings (asks for root, downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
