When your agent uses it

  • Amazon e-commerce research
  • Market validation
  • Competitor analysis
  • Traffic diagnosis

Example prompts

  • “/sif-amazon-research”

Workflow steps

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

  1. Define the decision being made: enter / not enter, launch / not launch, scale / optimize / stop, or diagnose root cause.
  2. Collect Sif evidence across the minimum necessary domains
  3. Cross-check evidence. Separate confirmed findings from hypotheses.
  4. Produce a business decision with confidence, evidence chain, risks, missing data, and next validation actions.

What it can do on your machine

Read from SKILL.md and the folder at commit 568be29. 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

    No scripts in the folder and no shell commands in SKILL.md.

    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

Sif Amazon Research loads about 1k tokens when it runs, and up to ~4.6k if it reads all its reference files. Until then it costs about 148 tokens; SKILL.md has 476 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~148
When it runs · the whole SKILL.md, loaded when a task matches
~1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~4.6k

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

Without a licence we can't republish the file, so here is its outline and opening line. It has 476 words (~1,024 tokens).

“Use Sif MCP as the evidence source whenever available. Do not infer final business conclusions from one metric alone.”
