Note that a "POW" is considered ANY prisoner that is not a member of your own faction. If you imprison your own colonist you can do whatever you want to them.
Most war crimes that check the conditions your POWs are kept in happen every day at 6 a.m. (when the game starts). These crimes will only be counted once per quadrum per prisoner, to avoid spamming you with daily counts.

Also note that the Geneva Convention on Rights of the Child are not just a wartime thing, so the crimes that are specifically against children count against your own colonies children, unlike every other one where it's okay to do to your colonists. The Geneva Convention also defines a child as a person below 15 years old, so 15 is the cutoff for those crimes.

This triggers if your Ideology's symbol is too similar to any of the protected symbols, like the red cross or blue triangle.
This triggers whenever a non-hostile pawn is damaged by your faction.
This triggers when a POW is killed by damage dealt by a member of your faction.
This triggers when using a Virus Replicator to infect POW.
This triggers whenever a POW is dealt damage by a member of your faction.
This triggers if a POW is kept in a cell that is less than half of the average impressiveness of all occupied bedrooms in your colony.
This triggers upon destruction or abandonment of ANY corpse that isn't a member of your colony. Burial, freezing, or entombment are the only way to avoid this.
This triggers if a POW has spent a month in prison while they have not been "infirm." A pawn is considered infirm if they are starving, naked, wearing damaged clothes, or have an infection. Note that the check as to whether a pawn is infirm only happens at 6 a.m. and 6 p.m., so quickly stripping and redressing a prisoner will not reset this timer.
This triggers upon releasing a POW who has an infection that they haven't built an immunity to, regardless of the circumstances of their release.
This triggers upon releasing a POW who doesn't have enough clothing, or clothing in disrepair. Note that this is based on what the PRISONER believes is "adequately clothed", so you do not need to dress a nudist, for example.
This triggers upon releasing a POW who is actively starving (as in suffering from the "malnutrition") hediff
This triggers if a female POW is in a cell with a male POW. I suggest downloading my "Vanilla Patches" mod here, as it has a feature that allows you to transfer prisoners to another bed.
This triggers if the average lighting in the cell is less than 30%
This triggers if any of the floors in the cell are tagged as "soil" or "water". This includes most natural floors.
This triggers if POWs are not assigned any bed other than a sleeping spot (meaning bedrolls, slab beds, and modded beds are acceptable accomodations).
This triggers if a POW is assigned a cell with a temperature outside of their comfortable temperature range.
This triggers if a POW is assigned a cell that has ANY flammable flooring or furniture but no firefoam popper (for example, an all-stone cell will not need a popper since it's naturally fireproof, but a cell with wooden furniture will need a popper)
This triggers if a POW is kept in a cell without the altar of THEIR IDEOLOGY.
This triggers if a POW is actively starving
This triggers if a POW has any thoughts that are gained from eating, such as "Ate raw food" or "Ate non-fungus plant cooked". Not that specifically the "ate non-human meat" thought is not counted, so you do not have to cater to the specific dietary preferences of a cannibal
This triggers if a POW has the "ate without table" thought. This isn't a joke, btw, forcing a prisoner to eat without a table is a war crime in real life.
This triggers if a POW has any unhappy nudity thought, or either of the damaged apparel thoughts ("ratty apparel" and "tattered apparel")
This triggers if a POW has ANY untended injury or disease that is more than 12 hours old
This triggers if a POW is kept in a cell alone. Note that this does not count if you don't have another prisoner you could put with them (for example, they are your only prisoner, or all of your other prisoners are the opposite gender)
This will trigger at the end of each quadrum. There is no way to pay prisoners in Rimworld, so you will always fail this. Make sure you have no prisoners at 6 a.m. On the first of each quadrum.
This will trigger if a pawn of your faction deals damage to a downed pawn. This only triggers if that downed pawn was the intended target, meaning if you miss another pawn and accidentally hit a downed pawn it DOES NOT COUNT. Beware of fast-firing weapons such as miniguns, since your pawn might accidentally hit them while they are down, but it will still count because that downed pawn was technically the intended target.
This triggers if you release or abandon a pawn. The only way to get release a pawn without triggering this is giving them directly back to their faction via drop pod (or selling them into slavery, but that's just a different war crime :P )
This triggers when recruiting a prisoner.
This triggers when dumping wastepacks off-map
This triggers if any of your pawns deal damage of a type that is considered "unethical". Those damage types are:
-Flame
-Burn
-Frostbite
-Digested (this damage type is only dealt by the harbinger tree in vanilla. You'd have to be doing some pretty ♥♥♥♥♥♥ up stuff if your pawn manages to do this. Or maybe you are just a furry, IDK.
-Nerve (the nerve spiker)
-BulletToxic
-ScratchToxic
-ToxicBite
-AcidBurn
This triggers when targetting a non-player pawn with any ability that is considered "unethical". Those abilities are:
-Neuroquake
[VANILLA PSYCASTS EXPANDED]:
-Drain Psyessence
-Mass Hallucination
-Psychic Shock
-Aggressive Heat Dump
-Psychic Drone
-Word of Foretelling
-Health Swap
-Word of Fear
-Liferot
[VANILLA PSYCASTS EXPANDED-PUPPETEER ADDON]:
-Brain Cut
-Degrade
-Ascension
This triggers upon enslaving someone, simple as. It also triggers when using Mindbreak from Vanilla Psycasts Expanded, or Subjugation or Puppet from the Puppeteer addon.
This triggers after successfully raiding a work site.
This triggers after leaving a site or abandoning a map that has traps (such as landmines or spike traps) in it that you have placed.
Since you are not capable of marking a minefield in Rimworld, this triggers whenever you place any trap.
This triggers if any of your children are below 10% learning need, or if any child is in prison (since children cannot be educated while in prison in Rimworld)
This functions exactly the same as "holding prisoners of war in a combat zone", except you can only hold a child in prison for 3 days instead of 15.
This triggers on every child who is kept in prison. There is no way to avoid this if a child is imprisoned.
This triggers whenever a child of your colony does damage to any non-colony person.
This triggers whenever a colonist damages a non-colonist with toxgas, simple as.
This triggers whenever a colonist damages a non-colonist with any of the pathogen gasses.
