What it does
Ddmemo is an agent skill from Gerstep/cybos. Generate comprehensive investment memos for cyber•Fund investment committee decisions. Use when creating DD memos or investment analysis documents.

It sits in Education.
When your agent uses it
- Creating DD memos
- Investment analysis documents
Example prompts
- “/ddmemo”
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- GATHER: Load all research and context
- ANALYZE: Deep strategic analysis with memo-analyst (Opus)
- WRITE: Template-driven memo with memo-writer (Sonnet)
- REVIEW: Completeness and consistency check
- OUTPUT: Save to deal memo folder
- LOG: Record memo generation
What it can do on your machine
Read from SKILL.md and the folder at commit 2f0646f. 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
No URLs in SKILL.md.
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
Ddmemo loads about 599 tokens when it runs. Until then it costs about 39 tokens; SKILL.md has 238 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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 238 words (~599 tokens).
