What it does
Token Dashboard is an agent skill from alexgreensh/token-optimizer. Opens the Token Optimizer dashboard in the browser (context usage, quality, savings). Use when the user asks to see the dashboard.
Its SKILL.md is about 950 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows. The repository describes itself as: Find the ghost tokens. Fix them. Survive compaction. Avoid context quality decay.
When your agent uses it
- The user asks to see the dashboard
Example prompts
- “Use the token-dashboard skill to open the Token Optimizer dashboard in the browser (context usage, quality, savings)”
- “/token-dashboard”
Requirements
- Python 3
Workflow steps
2 steps, taken from the first numbered list in SKILL.md.
- Resolve runtime and measure.py path
- Collect and open
What it can do on your machine
Read from SKILL.md and the folder at commit 723c19b. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
python3
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Token Dashboard loads about 950 tokens when it runs. Until then it costs about 37 tokens; SKILL.md has 173 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 173 words (~950 tokens).
“Opens an up-to-date dashboard showing your context usage trends, quality scores, session history, and skill management.”
