What it does
Cre Office is an agent skill from ahacker-1/cre-agent-skills. CRE Office analysis suite - 8 specialist skills for U.S. office acquisitions, refinancings, lease-up, tenant credit, TI/LC underwriting, financing fit, and investment committee memo writing.
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 17 other files (for example `README.md`, `knowledge/office-benchmarks.md` and `knowledge/office-lease-structures.md`).
It sits in Business, Finance & HR, covering Banking and insurance and Real estate. The repository describes itself as: Commercial real estate AI agent skills for CRE underwriting, due diligence, financing, brokerage, legal and closing workflows - standalone prompts for Claude Code, ChatGPT… The licence is Apache-2.0.
When your agent uses it
- Tasks that involve Banking and insurance
- Tasks that involve Real estate
Example prompts
- “/cre-office”
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Read the user's request to determine which office skill is needed.
- Load the full skill file, for example: Read skills/office-ti-lc-underwriting-model-builder.md.
- Load relevant knowledge files when the skill asks for them.
- Follow the Strategy steps exactly.
- Produce output in the specified format.
- Run Quality Checks before delivering results.
What it can do on your machine
Read from SKILL.md and the folder at commit a9a4e29. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
theaiconsultingnetwork.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Cre Office loads about 1.3k tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 521 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
