What it does
Meaningful Identifiers is an agent skill from hashintel/hash. Naming guidance for callback parameters and local variables in TypeScript. Use when writing or refactoring loops, array callbacks (map/filter/find/reduce), or local accumulators.
Its SKILL.md is about 310 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 Refactoring. It works with TypeScript. The repository describes itself as: 🚀 The open-source, multi-tenant platform for self-building knowledge graphs and simulation. The licence is AGPL-3.0.
When your agent uses it
- Refactoring loops
- Array callbacks (map/filter/find/reduce)
- Local accumulators
Example prompts
- “/meaningful-identifiers”
What it can do on your machine
Read from SKILL.md and the folder at commit 1fa0c7b. 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
Meaningful Identifiers loads about 308 tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 96 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.

Meaningful identifiers
Callback parameters and local variables must describe the value they hold.
Rules
- Name array callback params after the element's domain type:
batches.map((batch) => …),bins.filter((bin) => …),checkpoints.find((checkpoint) => …). Never reuseright/left/columnfor values that are not sort operands or table columns. - Name
reduceaccumulators after what they accumulate:sum/totalfor a running total, notstep. - Name percentile/ratio arguments for the quantity they represent
(
percentileRank,multiplier), not an unrelated domain noun.
Leave correct uses untouched
- Sort comparators:
(left, right) => left - right. (column) => column.keyover a real.columnsarray.for (const row of …Rows)where the items are genuinely rows.
