memstack-headroom

A command that checks whether the TokenStack proxy is running and tells you where to find token-saving information. A proxy is a service that passes requests between a coding tool and another service.

In plain words
What is it for?
Use it to check local proxy health and review token savings, costs, and per-agent usage in the TokenStack dashboard.
Why use it?
It gives a quick offline check and explains how to start the proxy if it is not available, without pretending to provide statistics it cannot access.

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.

Made for: Claude Code.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 149 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 1 finding. Scan, not verified.
Origin original No closer match found in the catalogue.
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.

Security

Grade A, and why

memstack-headroom scanned grade A with 1 finding 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 2d 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.

What it actually says

Check TokenStack proxy status.

First check if the TokenStack proxy is running:

curl -s -m 2 http://127.0.0.1:8787/health

If it responds, the proxy is up and routing Claude Code traffic.

The proxy does not expose a stats endpoint. Report token savings from the dashboard instead:

  • Proxy indicator: PRO or FREE badge with session and 30-day percentages
  • Overview header: session and lifetime tokens saved
  • Burn Report: per-transform breakdown, estimated cost, and per-agent split

If the proxy is not running, respond with:

"TokenStack is offline. Start it with: python -m memstack_skill_loader dashboard --with-proxy"

Changes

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.
