Method shorthand in return objects for JSDoc preservation. An agent skill from EpicenterHQ/epicenter.
- Works in 3 steps: JSDoc attaches to the method definition… → Method shorthand uses function semantics… → No separate helper needed - if it's only…

What it does
Method Shorthand Jsdoc is an agent skill from EpicenterHQ/epicenter. Method shorthand in return objects for JSDoc preservation. Use when factory functions have internal helpers that should expose docs, or hovering over returned methods shows no JSDoc.
Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Technical documentation. The repository describes itself as: Open-source, local-first apps.
When your agent uses it
- Factory functions have internal helpers that should expose docs
- Hovering over returned methods shows no JSDoc
Example prompts
- “/method-shorthand-jsdoc”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- JSDoc attaches to the method definition site - when methods are inline in the return object, the JSDoc is directly on the property…
- Method shorthand uses function semantics - this is bound to the object, so this.getEpoch() works
- No separate helper needed - if it's only used by sibling methods, it belongs in the same object
What it can do on your machine
Read from SKILL.md and the folder at commit 5b4bb69. 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
Method Shorthand Jsdoc loads about 1.9k tokens when it runs. Until then it costs about 51 tokens; SKILL.md has 529 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
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 529 words (~1,938 tokens).
“When factory functions have helper functions that are only used by returned methods, move them INTO the return object using method shorthand. This ensures JSDoc comments are properly passed through to consumers.”
