Server Side Tracking

What it does

When your agent uses it

• Tasks that involve Backend development
• Tasks that involve Privacy and GDPR

Example prompts

• “/server-side-tracking”

Requirements

• Python 3
• Docker

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

1. 1Compare client-side events sent vs. server-side events received (expect < 2% loss)
2. 2Verify consent state is correctly parsed for all forwarded events
3. 3Confirm no PII is forwarded to destinations where consent is denied
4. 4Check that IP anonymization is applied before all third-party forwarding
5. 5Validate first-party cookie durations match policy
6. 6Review server logs for any unexpected outbound connections

What it can do on your machine

Read from SKILL.md and the folder at commit 9b2ef9e. 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

  Ships 1 file in scripts/ (Python), which the agent can run.

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  Hosts in commands or code, which the agent is likely to contact:

  • data.pinnacle-ecommerce.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

Server Side Tracking loads about 2.4k tokens when it runs, and up to ~3.5k if it reads all its reference files. Until then it costs about 65 tokens; SKILL.md has 887 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~65

When it runs · the whole SKILL.md, loaded when a task matches

~2.4k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~3.5k

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

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); the scripts in this folder are not scanned.
