What it does

Notion Migration Deep Dive is an agent skill from jeremylongshore/tons-of-skills-marketplace. Design and execute a reversible Notion content or schema migration with identity maps, checkpoints, and reconciliation. Use when moving data between schemas, workspaces, versions, or external systems. Trigger with "migrate Notion data", "upgrade Notion schema", or "backfill Notion pages".

Its SKILL.md is about 980 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/official-docs.md`). Compatibility notes: Designed for Claude Code; live Notion actions require network access and explicit approval

It sits in Business, Finance & HR, covering Accounting and bookkeeping and Database migrations. It works with Notion. 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

  • Moving data between schemas
  • External systems
  • With migrate Notion data
  • Upgrade Notion schema

Example prompts

  • “migrate Notion data”
  • “upgrade Notion schema”
  • “backfill Notion pages”
  • “/notion-migration-deep-dive”

Requirements

  • Compatibility (from SKILL.md): Designed for Claude Code; live Notion actions require network access and explicit approval
  • Pre-approved tools (allowed-tools): Read, Glob, Grep, Write, Edit

Workflow steps

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

  1. Freeze the source and destination contracts, selected versions, owners, and acceptance metrics.
  2. Inventory schemas, stable IDs, relations, unsupported blocks, files, user mappings, and sensitive fields.
  3. Create deterministic identity, property, relation, content, and lifecycle mappings with quarantine rules.
  4. Run a synthetic dry run and then a small approved canary with resumable checkpoints.
  5. Migrate in bounded batches; persist destination IDs before advancing source checkpoints.
  6. Reconcile counts, hashes, relations, block order, files, quarantines, late changes, and rollback eligibility.

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
    • 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

    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.

  • Compatibility

    Designed for Claude Code; live Notion actions require network access and explicit approval

    From compatibility in the SKILL.md frontmatter.

Context cost

Notion Migration Deep Dive loads about 980 tokens when it runs, and up to ~1.5k if it reads all its reference files. Until then it costs about 79 tokens; SKILL.md has 398 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~79
When it runs · the whole SKILL.md, loaded when a task matches
~980
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.5k

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.

Notion Migration Reconciliation

Overview

Design and execute a reversible Notion content or schema migration with identity maps, checkpoints, and reconciliation.. This workflow produces an auditable decision or artifact before any live action.

Prerequisites

  • Current first-party Notion documentation and the selected integration's tested API-version contract.
  • A named workspace owner, content or data owner, and operation owner.
  • Synthetic or approved non-production fixtures with secrets and workspace content removed.

Current Contract

Migration contracts must distinguish database containers, data sources, pages, properties, blocks, files, users, relations, and trash state. Search and export order are not durable migration checkpoints. Recheck the dated evidence map before relying on mutable fields, endpoints, versions, limits, or delivery behavior.

Authentication

Use separate least-privilege source-read and destination-write identities where possible. Keep identity maps and sensitive content encrypted and tenant-scoped.

Instructions

  1. Freeze the source and destination contracts, selected versions, owners, and acceptance metrics.
  2. Inventory schemas, stable IDs, relations, unsupported blocks, files, user mappings, and sensitive fields.
  3. Create deterministic identity, property, relation, content, and lifecycle mappings with quarantine rules.
  4. Run a synthetic dry run and then a small approved canary with resumable checkpoints.
  5. Migrate in bounded batches; persist destination IDs before advancing source checkpoints.
  6. Reconcile counts, hashes, relations, block order, files, quarantines, late changes, and rollback eligibility.

Tool Discipline

Use Read, Glob, and Grep to inspect documentation, configuration, code, fixtures, and evidence. Use Write and Edit only for approved repository artifacts. Invocation alone does not authorize network access, credentials, workspace content, user data, file transfer, deployment, capability or sharing changes, writes, spend, or deletion.

Show full SKILL.md (140 more words)Show less

Approval Boundaries

Require source and destination owners before reads or writes; require separate approval for historical export, user data, backfill, trash, or cutover.

Error Handling

  • Do not use titles as unique identities.
  • Do not advance a checkpoint after partial destination acknowledgement.
  • Freeze cutover on unexplained count or relation drift.

Output

Return the contracts, mappings, checkpoints, batch ledger, reconciliation, quarantine, cutover decision, and rollback package. Identify assumptions, owners, expirations, and evidence gaps explicitly.

Examples

  • Migrate one legacy database schema to current data-source operations.
  • Resume a cross-workspace page migration without duplicating accepted pages.

Validation

Exercise and record these paths with expected and observed results:

  • empty values
  • relation cycles
  • unsupported block
  • expired file
  • partial batch
  • late source change

Resources

  • Current first-party evidence map — recheck dated sources before relying on mutable behavior.
  • Treat observed tenant behavior as environment-specific evidence, never a universal Notion guarantee.
