Neat concept! Very different from anything I've read so far. Questions that popped up after reading your example:
- Is the manual complete? Is it ancient, containing old languages or archaic text?
- is it a manual in the technical sense, containing schematics? More like an encyclopedia, or a creed?
- Can Agents add, change or remove sections in/from the manual?
If you go down the route of the religious aspects you mentioned in your inspiration example:
- Does such a manual leave its contents open to interpretation?
- Can the content be misinterpreted, in any way, and if so, to what extent ?
- Can it be spawn a religious offshoot or sect? Can it unify people? End wars? Start crusades?
Not trying to push you into going down a certain path or anything, I'm merely pondering the ramifications of your specific example!
