A command for checking and upgrading the Q-Command System installation to its latest version. It checks the current version, asks for permission, runs the upgrade script, and verifies the result.

Use it to inspect the installed Q-Command System version, review local release information, request approval for an upgrade, and confirm that the upgrade succeeded.

It provides a controlled way to update the local command system without guessing which version is installed. The pre-flight checks make the upgrade steps explicit.

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	$0.00008	$0.01929
Opus 5	$0.00004	$0.00964
Sonnet 5	$0.00002	$0.00386
Haiku 4.5	$0.00001	$0.00193

Security

Grade E, and why

q-upgrade scanned grade E 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 5d 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.

Upgrade Q-Command System

Purpose: Efficiently check and upgrade to the latest Q-Command System version.

Efficiency: This command uses a script-based approach that reduces token usage by ~85% compared to individual file fetches.

MANDATORY PRE-FLIGHT CHECKLIST

STOP. Before proceeding, confirm:

1. I will check versions BEFORE making changes
2. I will get explicit user permission before upgrading
3. I will use the upgrade SCRIPT (not individual WebFetch calls)
4. I will verify the upgrade completed successfully

Step 1: Check Local Version

1.1 Read Local Version Info

cat .q-system/version.yaml 2>/dev/null || cat .q-system/version 2>/dev/null || echo "No version file found"

Command executed
Local version identified: ____________________

Parse the version:

If version.yaml: Look for q_system.version
If version file: Single line with version number
If neither: Assume pre-2.1 installation

1.2 Check for releases.yaml (if exists locally)

cat .q-system/releases.yaml 2>/dev/null | head -5 || echo "No local releases.yaml"

VERIFICATION GATE 1:

Local installation:
- Version: [version or "unknown"]
- Version file type: [version.yaml / version / none]

Step 2: Fetch Remote Version Info

2.1 Fetch releases.yaml (Small File - Efficient)

Use WebFetch to get:

https://raw.githubusercontent.com/contactTAM/q-command-system/main/templates/releases.yaml

Fetch attempted
Latest version identified: ____________________
Commands changed since local version: ____________________

2.2 Parse Release Information

From releases.yaml, identify:

current_version: The latest available version
Find releases between local version and current version
Aggregate commands_changed from all intermediate releases
Note any breaking_changes or migration_notes

VERIFICATION GATE 2:

Version comparison:
- Local version:  [local]
- Latest version: [remote]
- Status: [Up to date / Upgrade available]
- Commands changed: [list or "all"]

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.

It adds 8 tokens to every session and 1,929 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it E with 3 findings (downloads and executes remote code, recursive force delete, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
