What it does
Reshard C4 Data is an agent skill from lazyFrogLOL/Harness_Engineering. Guidance for data resharding tasks that involve reorganizing files across directory structures with constraints on file sizes and directory contents. This skill applies when redistributing datasets, splitting large files, or reorganizing data into shards while maintaining constraints like maximum files per directory or maximum file sizes. Use when tasks involve resharding, data partitioning, or directory-constrained file reorganization.
Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
When your agent uses it
- Tasks involve resharding
- Data partitioning
- Directory-constrained file reorganization
Example prompts
- “/reshard-c4-data”
Requirements
- Python 3
Workflow steps
5 steps, taken from the step headings in SKILL.md.
- Analyze Input Data
- Validate Constraint Mathematics
- Design Hierarchical Output Structure
- Implement File Distribution
- Generate Reconstruction Metadata
What it can do on your machine
Read from SKILL.md and the folder at commit cae3b25. 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 python).
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
Reshard C4 Data loads about 1.5k tokens when it runs. Until then it costs about 114 tokens; SKILL.md has 548 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 548 words (~1,464 tokens).
“This skill provides guidance for data resharding tasks where files must be reorganized across a directory structure while respecting constraints such as maximum file size limits and maximum items per directory. These tasks require careful consideration of how constraints apply…”
