What it does
Importer Scaffolder is an agent skill from mohitagw15856/pm-claude-skills. Use when asked to build an importer from a competitor's export, migrate users' data from another tool, map a CSV or JSON export onto my data model, or make switching to my project easy. Given a sample export (CSV or JSON), produces a field mapping table, an importer code skeleton, a rule that unmatched records are kept rather than dropped, and test fixtures including the awkward cases. For a database migration inside one system, use database-migration-plan.
Its SKILL.md is about 1.1k 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 Databases, covering Test data and fixtures, Database migrations and CSV and tabular files. The repository describes itself as: 1255 professional Agent Skills for Claude, ChatGPT, Gemini, Cursor & Codex — PRDs, postmortems, leases, medical bills, layoffs, go-bags, new countries. Plain markdown, MIT, in… The licence is MIT.
When your agent uses it
- Asked to build an importer from a competitors export
- Migrate users data from another tool
- JSON export onto my data model
- Make switching to my project easy
Example prompts
- “s export, migrate users”
- “/importer-scaffolder”
Workflow steps
6 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 1cbf1f0. 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
Importer Scaffolder loads about 1.1k tokens when it runs. Until then it costs about 120 tokens; SKILL.md has 580 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.

Importer Scaffolder
People switch tools when leaving costs them nothing, and an importer is how a small project removes that cost. Importers fail quietly: a column is renamed, a date is in another format, a record has no match, and data disappears without anyone noticing. This skill builds an importer from a real sample export, with a mapping that is explicit and a rule that nothing is silently dropped.
Required Inputs
Ask for these if not provided:
- A sample export: a few rows of CSV or a JSON excerpt, with any personal data replaced
- The source tool and how users produce the export
- Your data model: the target fields, types and required fields
- Your language and stack for the importer
- Where unmatched data should go: a notes field, an extras column, or a separate file
Output Structure
1. Source profile
What the sample shows: format, encoding, delimiter, header names, date and number formats, nested fields, and anything ambiguous. List assumptions explicitly.
2. Field mapping table
| Source field | Example value | Target field | Transform | Required? | If missing or invalid |
|---|
Every source field appears in the table, mapped or not. Unmapped fields go to the extras destination named in the inputs.
3. The keep-everything rule
State it in the code and the docs: no source record is dropped. A record that fails validation is imported with what could be parsed, flagged, and listed in an import report; its raw source is preserved in the extras destination.
4. Importer skeleton
Code in the requested language with these parts, each a small function:
read(source): streams rows; detects encoding and delimiter; never loads a huge file wholemapRow(row): applies the mapping table; returns{ record, warnings, extras }validate(record): required fields and types; returns problems without throwingwrite(record): idempotent upsert keyed on a stable source ID, so re-running an import does not duplicate datareport(): counts of imported, imported with warnings, and per-warning examples
Include a dry-run mode that prints the report without writing.
Show full SKILL.md (254 more words)Show less
5. Test fixtures
Fixture files plus the expected result for each:
- the happy path (three normal rows)
- a renamed or reordered header
- an empty required field
- a malformed date and a number with a thousands separator
- non-ASCII text (accents, Chinese characters, emoji)
- a duplicate row (checks idempotency)
- a row with extra unknown columns (checks they land in extras)
6. User-facing instructions
Five to eight steps telling users how to export from the source tool and import, including what the import report means.
Quality Checks
- Every source field in the sample appears in the mapping table
- The code imports invalid records with a flag instead of dropping them
- Unmapped fields are preserved in the named extras destination
- Re-running the import on the same file creates no duplicates
- A dry-run mode exists and writes nothing
- Fixtures cover non-ASCII text, a malformed date and a duplicate row
- The sample data contains no real personal data
Anti-Patterns
- Silent drops. A skipped row is lost data the user may never notice.
- Mapping by column position. Exports reorder columns; map by header name.
- Loading the whole file into memory. Real exports are bigger than samples.
- Guessing ambiguous dates. If 03/04 could be either order, ask or detect from the whole file, and record the choice.
Example Trigger Phrases
- "Build an importer for Trello JSON exports into my app."
- "Here's a CSV export from Notion, map it onto my data model."
- "Make it easy for users to switch from [competitor] to my project."
- "Write a CSV importer that never drops rows."
