Dorsi flexion and eversion are its main actions. I just can't justify this your question.
It's a Flexor Tendon.

Extensor carpi radialis longus and Extensor carpi radialis brevis.
There a lot of tendons on the plantar side of the foot. Off the top of my head... Tendon of the flexor digitorum longus Tendon of the flexor digitorum brevis Tendon of the flexor hallucis longus Tendon of the flexor hallucis brevis Tendon of the flexor digiti minimi brevis Tendon of the fibularis longus Tendon of the tibialis posterior Tendons of the lumbricals Tendons of the plantar interosseous muscles Tendon of the abductor hallucis Tendon of the adductor hallucis Tendon of the abductor digiti minimi There are also a bunch of ligaments.
flexor hallucis longus, flexor hallucis brevis
There are a variety of foot tendons. Some of these include the tendon of tibialis anterior, tendon of extensor halluces longus, and tendons of extensor digitorum longus.

Extensor muscles open a joint and are the opposite to flexor muscles, which close it. I imagine triceps are extensor, while biceps are flexor.

Extensor carpi radialis longus and Extensor carpi radialis brevis.

Extensor. It will extend the neck and adduct the scapula.
There's more than one: flexor carpi radialis palmaris longus flexor carpi ulnaris pronator teres flexor digitorum superficialis (sublimis) flexor digitorum profundus flexor pollicis longus pronator quadratus brachioradialis extensor carpi radialis longus extensor carpi radialis brevis extensor digitorum (communis) extensor digiti minimi (proprius) extensor carpi ulnaris abductor pollicis longus extensor pollicis brevis extensor pollicis longus extensor indicis (proprius) supinator anconeus
extensor digitorum, extensor indicis, extensor digiti minimi, flexor digitorum superficialis, and the flexor digitorum profundus. There are also extrinsic muscles that work only in the thumb; these include the flexor pollicis longus, extensor pollicis longus, extensor pollicis brevis, and adbuctor pollicis longus
The muscles of the legs do not follow the generalization that extensor muscles are on the posterior and flexor muscles are on the anterior.
All skeletal muscles will have a flexor and an extensor. The flexor bends the joint. The extensor straightens it out again.
Triceps muscle is not a flexor. Triceps is an extensor of elbow joint. Biceps muscle is flexor.
