What it can do on your machine
Read from SKILL.md and the folder at commit a062fb4. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
mcp__cogny__klaviyo__*mcp__cogny__mailchimp__*mcp__cogny__rule__*mcp__cogny__get_a_newsletter__*mcp__cogny__create_findingmcp__cogny__write_context_nodemcp__cogny__read_context_nodemcp__klaviyo__*mcp__mailchimp__*mcp__rule__*
…and 5 more on the same allowed-tools line.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are json).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
cogny.com
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
Revenue Audit loads about 3.1k tokens when it runs. Until then it costs about 49 tokens; SKILL.md has 1,212 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: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
allowed-tools: mcp__cogny__klaviyo__*, mcp__cogny__mailchimp__*, mcp__cogny__rule__*, mcp__cogny__get_a_newsletter_
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
Without a licence we can't republish the file, so here is its outline and opening line. It has 1,212 words (~3,060 tokens).
“The "email growth consultant in a box." Scans your connected ESP for the revenue sitting on the table and ranks every finding by estimated dollar impact, so you know exactly what to fix first.”
