What it does
Ddd Tactical Patterns is an agent skill from aiskillstore/marketplace. Apply DDD tactical patterns in code using entities, value objects, aggregates, repositories, and domain events with explicit invariants.
Its SKILL.md is about 410 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/tactical-checklist.md` and `skill-report.json`).
It sits in Development, covering Domain-driven design. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.
When your agent uses it
- Tasks that involve Domain-driven design
Example prompts
- “/ddd-tactical-patterns”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Identify invariants first and design aggregates around them.
- Model immutable value objects for validated concepts.
- Keep domain behavior in domain objects, not controllers.
- Emit domain events for meaningful state transitions.
- Keep repositories at aggregate root boundaries.
What it can do on your machine
Read from SKILL.md and the folder at commit ad8daf7. 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 (its code samples are typescript).
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
Ddd Tactical Patterns loads about 413 tokens when it runs, and up to ~566 if it reads all its reference files. Until then it costs about 40 tokens; SKILL.md has 136 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 136 words (~413 tokens).
