How do we determine which species is the oxidizing / reducing agent?

The oxidizing agent is reduced in the process of bringing about oxidation. The reducing agent is oxidized in the process of bringing about reduction.

Oxidizing Agent: its the species that is being reduced as it removes the electron from a substance
Some examples include: O2,O3,Fe3+
Reducing Agent: the species that is being oxidized as it supplies electrons to a substance
Examples include: H2, H2S

Oxidizing agents help substances oxidize by being reduced. The opposite is true for reducing agents.

So, by looking at a half reaction, you can tell if its an oxidizing agent if electrons are on the reactants side and you can tell if its a reducing agent if the electrons are on the products side?

The oxidizing agent is the substance that's getting reduced. The reducing agent is the substance that's getting oxidized.

An oxidizing agent gains electrons which can be seen through a half-reaction. The reducing agent then loses electrons.

For me, it helps to remember OIL (oxidation is losing e-) RIG (reduction is gaining e-). If a species is losing electrons when going from reactants to products, the oxidation number increases, so the species is being oxidized and is a reducing agent. However, if a species is gaining electrons when going from reactants to products, the oxidation number decreases, so the species is being reduced and is an oxidizing agent.
