PDF is read with pypdf (page markers, scan warning, encrypted files refused), Outlook .msg with olefile as a container like an .eml, and a .msg attached to a mail is quoted. Both packages are in tools/requirements.txt and imported only when such a file is derived, so a missing one stops that format alone. doctor reports one import-filter line per package-backed format.

Reference
Lookup pages: the command surface, exit codes and gates, the skill catalogue, the page types. A reference page describes what is, not how to use it or why it is so - and wherever a source for it exists in the code, it is generated from that source and checked against it rather than written by hand.
- Command reference - every
wikitoolcommand, one page per group, generated from the same records astools/wikitool <command> -h. - Exit codes and gates - which commands can stop and wait for a person, and why.
- Skill catalogue - the skills the stack ships, what each does and which requests
start it, generated from their
SKILL.md. - Page types - every page type the stack ships for
kb/, its subtypes, where its pages are written and its required fields, generated from the type-specs. - Configuration - the environment variables
wikitoolreads and the per-checkout files an operator may create. The shape of each file is generated from the record its loader reads it with; the environment variables and what each setting does are written by hand.
The skill catalogue and the page types describe the stack's shipped defaults, which an instance
may change or extend; tools/wikitool instructions list and tools/wikitool types describe <type>
show what one instance has.
