I think I have a good grasp on them, but thought I'd post some examples and get input.

Buffer seems very much like the "Tank" function, both in terms of protection and battlefield control, including some area denial.

• "I Buffer my injured friend. If they want to derez him, they'll have to attack me first." (Defend/taunt)
• "I pull out my tricked out arc wheel and throw some fancy ricocheting shots to Buffer the enemy out of cover and into the open." (Seizing ground/area denial)
• "I Buffer the collapsing ceiling, using myself as a support pillar so the Capacitor has time to Restore the structure."
• "I Buffer the lone Troubleshooter with my Intimidator ability, hoping to 'convince' him that he didn't see anything." (Breaker ability)

Crash seems pretty straightforward.

• "My Daemon pulls out her blunderbuss and Crashes at point blank range, rather than Ping from a distance."
• "Since the Filcher's lockpicking failed, I'll just Crash the lock with my nodecutter."

Echo is illusion, deception, and emotion (?).

• "I Echo the boss so that he thinks it was his own idea, rather than my suggestion."
• "I Echo the safe's timestamps so that no one knows when I took out the contents."
• "I Echo the crowd with the faction's villainous deeds, trying to rile them up into rioting."

Find is straight up perception and sorting through information.

• "I turn my Find function onto the crime scene to look for clues, tracks, and relevant timestamps.."
• "I'm not sure I trust this Daemon and try to Find if she's sincere."
• "Before I open the box, I see if I can Find any traps."

Goto is movement and agility.

• "I use my Goto to parkour my way over the fence."
• "I use my Goto to serpentine toward that cover and make myself a more difficult target for the sniper along the way."
• "I use my Goto to chart a shortcut and cut them off at the pass."

Link is the diplomacy and leadership skill.

• "I Link with our cohort to inspire courage and review our new tactics."
• "I Link with the shopkeeper to negotiate a better price."
• "I quickly and quietly lock eyes with our hidden ally, and Link with her to signal a warning before rejoining the conversation."
• "I Link with him, trying to convince him that I'm telling the truth, which I am."

Mask is stealth, thievery, and disguise, so a near-universal "thiefy" skill.

• "I Mask myself and try to pick some Coin off the target with my memknife while they're distracted."
• "I Mask myself to look like just another face in the crowd, minding my own business."
• "I load up the security guard's biometrics and Mask the scanner to make it think I'm authorized to be here."

Ping is repeated effort and/or calculated precision.

• "I target the enemy's weak spot and snipe with my Ping rifle."
• "Rather than Crashing with brute strength and risking a derez, I use Ping Fu to disable them, aiming for all 64 nodes in rapid succession."
• "I turn the logic probe up to full power and Ping my way through the I/O tower's locked door."

Restore manipulates the Archives and an object's 'save states.'

• "Instead of straight up picking the lock, I Restore the safe to an earlier, unlocked state."
• "I dig through the parking lot's Archives to recreate a wall that used to be here before the site was leveled and paved."
• "I rifle through the junkyard, Restoring items to see if I can recreate anything useful."
