Outlook

What it does

When your agent uses it

• The user mentions email
• Unread messages

Example prompts

• “/outlook”

Requirements

• Python 3
• A credential in SIG_MS_GRAPH_ACCESS_TOKEN

Workflow steps

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

1. 1Read /references/provider-config.yaml
2. 2Append the provider block to ~/.sig/config.yaml under providers
3. 3Ask the user: "Do you need a proxy to access this site?" — if yes, add networkProxy: under the provider in config.yaml
4. 4Run sig login ms-graph (with --network-proxy if proxy was specified)
5. 5Verify: run sig status ms-graph again — must show valid: true before proceeding

What it can do on your machine

Read from SKILL.md and the folder at commit 9ba8b35. 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 9 files in scripts/ (Python, from the files we listed), which the agent can run.

  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 these keys or tokens, usually read from environment variables:

  • SIG_MS_GRAPH_ACCESS_TOKEN

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Outlook loads about 2.6k tokens when it runs, and up to ~2.7k if it reads all its reference files. Until then it costs about 95 tokens; SKILL.md has 738 words of instructions outside code blocks.

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

~95

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

~2.6k

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

~2.7k

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.
