everyone is building copilot agents. most of them are mid.
the unlock isn't agents. it's skills.
here is the clearest way to think about it. i built a People and Culture Analyst skill this week and it made the difference obvious:
1. an agent is good at retrieval. it finds docs and pulls content. that is roughly 20% of the job.
2. the other 80% is synthesis across multiple documents, applying interpretation rules from a playbook, adapting tone for board vs ELT, knowing when to name individuals and when not to. that is procedural knowledge. an agent does not have that. a skill does.
3. a skill is a markdown file. instructions, resources, trigger phrases, sensitivity rules, output structures. you write it once, it sits in your SharePoint, copilot loads it only when the trigger fires, and your output is consistent every single time.
4. for this one i asked AI in SharePoint to write the skill for me. i described the role in plain English. "i want a HR analyst i can talk to naturally. not a search tool. something that thinks across pulse data, engagement, heat maps, and our comms playbook." it wrote the full skill file. briefing mode, pattern detection mode, communication drafting mode. sensitivity rules baked in.
5. then i tested it. "i have 10 minutes before my ELT meeting, brief me on people risks". the skill pulled from pulse surveys, sentiment summaries, org structure, peer recognition logs, cited every source, and framed it for an executive audience.
the same question without a skill gives you generic. with a skill it gives you your standard.
the workflow is the thing the model cannot get anywhere else. skills are how you capture it.
