What it does

Linear Migration Deep Dive is an agent skill from jeremylongshore/tons-of-skills-marketplace. Plan and execute a controlled migration into Linear using supported import assistants or the CLI importer. Use when moving issues from Jira, GitHub, Asana, Shortcut, another Linear workspace, or CSV. Trigger with "migrate to Linear", "import issues into Linear", or "plan Linear cutover".

Its SKILL.md is about 1.3k 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 verification requires network access and an approved Linear workspace credential

It sits in Backend & APIs, covering CSV and tabular files. It works with GitHub, Asana and Jira. 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 issues from Jira
  • Another Linear workspace
  • With migrate to Linear
  • Import issues into Linear

Example prompts

  • “migrate to Linear”
  • “import issues into Linear”
  • “plan Linear cutover”
  • “/linear-migration-deep-dive”

Requirements

  • A credential in API_KEY
  • A credential in ACCESS_TOKEN
  • Compatibility (from SKILL.md): Designed for Claude Code; live verification requires network access and an approved Linear workspace credential
  • Pre-approved tools (allowed-tools): Read, Glob, Grep, WebFetch, Write, Edit

Workflow steps

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

  1. Inventory source entities, volumes, users, teams, statuses, labels, projects, comments, attachments, timestamps, and compliance constraints.
  2. Choose a dedicated assistant when available; use the CLI only after documenting the data it cannot preserve.
  3. Define deterministic user, team, workflow, priority, estimate, and label mappings plus explicit exclusions.
  4. Run a small pilot into an approved destination team and validate counts, samples, permissions, links, and timestamps.
  5. Approve the cutover window, source freeze, communications, duplicate policy, rollback window, and accountable owners.
  6. After import, reconcile counts and sampled semantics, preserve receipts, and keep the legacy source read-only for the approved period.

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):

    • linear.app

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • API_KEY
    • ACCESS_TOKEN

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Designed for Claude Code; live verification requires network access and an approved Linear workspace credential

    From compatibility in the SKILL.md frontmatter.

Context cost

Linear Migration Deep Dive loads about 1.3k tokens when it runs, and up to ~2.1k if it reads all its reference files. Until then it costs about 79 tokens; SKILL.md has 523 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
~1.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.1k

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.

Linear Workspace Data Migration

Overview

Choose the supported importer that preserves the required data, pilot a bounded team, and prove mappings and rollback before cutover.

Prerequisites

  • The target repository, Linear workspace, environment, and accountable owner
  • Current security, privacy, compliance, capacity, and change-control requirements
  • An approved Linear credential only when a bounded live verification is necessary

Tool Discipline

Use Read, Glob, and Grep to inspect code, configuration, and evidence. Use WebFetch only for current first-party Linear documentation and package metadata. Use Write or Edit only for requested implementation with known target files. Never write credentials, customer content, unrestricted environment output, or unredacted GraphQL variables.

Current Contract

  • Imports require a workspace admin; dedicated import assistants are preferred because they retain more source data and can support bulk deletion for a limited time.
  • The CLI importer is for sources without a dedicated assistant and does not preserve all data such as comments or projects.
  • Re-importing the same source into the same team skips already-imported issues unless the prior import is deleted first.

Authentication

Use a personal API key only for owner-controlled scripts, OAuth with PKCE for user-delegated applications, or an enabled client-credentials grant for approved automation. Personal keys use Authorization: <API_KEY>; OAuth tokens use Authorization: Bearer <ACCESS_TOKEN>. Store credentials server-side in an approved secret manager.

Treat app approval, team access, scope changes, credential creation, rotation, revocation, and production access as owner-approved actions.

Instructions

  1. Inventory source entities, volumes, users, teams, statuses, labels, projects, comments, attachments, timestamps, and compliance constraints.
  2. Choose a dedicated assistant when available; use the CLI only after documenting the data it cannot preserve.
  3. Define deterministic user, team, workflow, priority, estimate, and label mappings plus explicit exclusions.
  4. Run a small pilot into an approved destination team and validate counts, samples, permissions, links, and timestamps.
  5. Approve the cutover window, source freeze, communications, duplicate policy, rollback window, and accountable owners.
  6. After import, reconcile counts and sampled semantics, preserve receipts, and keep the legacy source read-only for the approved period.

Approval Boundaries

Do not create, reveal, rotate, or revoke credentials; authorize an OAuth app; change scopes or team access; create, mutate, archive, or delete workspace data; configure or re-enable webhooks; import or export data; change roles, SCIM, or audit streaming; transmit diagnostics; change paid entitlements; or perform another production mutation without explicit approval from the accountable owner. Keep diagnosis read-only unless implementation was requested.

Output

Return the workspace and team scope, auth mode without credential value, files and contracts inspected, exact operation names, evidence collected, validation result, sensitive fields redacted, remaining risk, accountable owner, approval state, and rollback or next action.

Error Handling

ConditionResponse
Unsupported fieldRecord the loss and choose an archive or alternate migration path before cutover.
User mapping ambiguousRequire owner-confirmed mapping; do not create or merge identities automatically.
Pilot incorrectDelete the pilot only while the supported option remains and after approval, then repair mappings.
Rollback window unknownDo not cut over until current importer deletion behavior is verified.

Examples

Use a compact handoff that makes scope, mutation authority, and verification evidence reviewable.

Input:

text
source=jira; teams=2; issues=500; mode=pilot; comments=required

Expected handoff:

text
method=dedicated-assistant; mappings=review; cutover=not-approved
