What it does

Salesforce Migration Deep Dive is an agent skill from jeremylongshore/tons-of-skills-marketplace. Run a dependency-ordered Salesforce data migration with mapping, external IDs, Bulk API selection, quarantine, cutover, reconciliation, and rollback. Use when conducting large migrations. Trigger with "migrate Salesforce data".

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. Compatibility notes: Designed for Claude Code; data extraction, transformation, loading, deletion, and cutover require source, target, privacy, and business-owner approval

It sits in Sales & Support, covering CRM management and Accounting and bookkeeping. It works with Salesforce. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.

When your agent uses it

  • Conducting large migrations
  • With migrate Salesforce data

Example prompts

  • “migrate Salesforce data”
  • “/salesforce-migration-deep-dive”

Requirements

  • Compatibility (from SKILL.md): Designed for Claude Code; data extraction, transformation, loading, deletion, and cutover require source, target, privacy, and business-owner approval
  • Pre-approved tools (allowed-tools): Read, Glob, Grep, WebFetch, Write, Edit

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. Freeze scope, source snapshot or watermark, objects, fields, filters, counts, classifications, owners, and cutover criteria.
  2. Profile data quality and map source keys, target external IDs, required fields, lookups, parents, children, owners, picklists, and…
  3. Discover target API versions, metadata, permissions, sharing, validation, automation, duplicate rules, storage, limits, and lock behavior.
  4. Order deterministic migration waves, create immutable manifests and hashes, and separate valid, rejected, and quarantined records.
  5. Run dry-run transformations, then small synthetic and representative non-production canaries with full dependency reconciliation.
  6. Execute approved production waves within limits; preserve job IDs and result files and never blindly replay uncertain batches.
  7. Re-query by stable keys, reconcile counts, values, relationships, ownership, duplicates, and downstream effects; cut over or roll back.

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Glob
    • Grep
    • WebFetch
    • Write
    • Edit

    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

    Links to these hosts (documentation or services it may open):

    • developer.salesforce.com
    • help.salesforce.com

    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.

  • Compatibility

    Designed for Claude Code; data extraction, transformation, loading, deletion, and cutover require source, target, privacy, and business-owner approval

    From compatibility in the SKILL.md frontmatter.

Context cost

Salesforce Migration Deep Dive loads about 1.1k tokens when it runs. Until then it costs about 65 tokens; SKILL.md has 439 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~65
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

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.

Salesforce Governed Data Migration

Overview

Move data as a controlled accounting exercise in which every source key, transformation, dependency, target result, exception, and rollback obligation is traceable.

Prerequisites

  • Source and target systems, objects, owners, data classes, migration scope, cutover window, and success criteria
  • Current source schema, Salesforce metadata, external IDs, relationships, validation, automation, sharing, and limits
  • Mapping and transform rules, quality thresholds, quarantine, reconciliation, rollback or compensating action, and retention plan

Tool Discipline

Use Read, Glob, and Grep to inspect approved repository and evidence files, WebFetch to re-check current first-party Salesforce documentation, and Write or Edit only for secretless plans, fixtures, configuration, and redacted receipts.

Current Contract

Bulk API 2.0 supports asynchronous CSV ingest and query, including insert, update, upsert, and delete where documented and entitled. Data Loader and other tools have separate contracts; object behavior, automation, and limits remain org-specific.

Authentication

Separate source read, transformation, target write, verification, and support access. Keep tokens and private keys out of migration files; encrypt and expire approved extracts and restrict raw personal data.

Instructions

  1. Freeze scope, source snapshot or watermark, objects, fields, filters, counts, classifications, owners, and cutover criteria.
  2. Profile data quality and map source keys, target external IDs, required fields, lookups, parents, children, owners, picklists, and transforms.
  3. Discover target API versions, metadata, permissions, sharing, validation, automation, duplicate rules, storage, limits, and lock behavior.
  4. Order deterministic migration waves, create immutable manifests and hashes, and separate valid, rejected, and quarantined records.
  5. Run dry-run transformations, then small synthetic and representative non-production canaries with full dependency reconciliation.
  6. Execute approved production waves within limits; preserve job IDs and result files and never blindly replay uncertain batches.
  7. Re-query by stable keys, reconcile counts, values, relationships, ownership, duplicates, and downstream effects; cut over or roll back.

Approval Boundaries

Do not extract production data, disable automation, change external IDs, overwrite owners, delete records, start a load, or cut over without owners.

Output

Return scope and snapshot, mappings, quality report, dependency graph, manifests, job results, quarantine, reconciliation, cutover decision, rollback, and expiry.

Error Handling

ConditionResponse
External IDs are not uniqueStop upsert planning and resolve the source and target identity model.
Automation changes migrated valuesClassify the intended behavior, revise transforms or approved automation, and rerun the canary.
Job outcome is incomplete or unavailableDo not replay; retrieve result evidence and reconcile target keys first.

Example

A redacted completion receipt might look like this:

text
migration=legacy-accounts; source=watermarked; rows=850000; waves=6; success=849920; quarantine=80; reconcile=exact

Resources

Next Steps

Run the workflow first in the lowest-risk authorized org and preserve its redacted receipt. Schedule a review against the next Salesforce seasonal release and the customer change calendar.
