| description | Creates or updates a Linear work item — Project (Epic), Issue (Story), or sub-Issue (Sub-task) — following organizational best practices. Polymorphic: dispatches internally on issue_type to save_project (Epic) or save_issue (Story / Sub-task). Enforces description quality (three audiences), Gherkin acceptance criteria, project-as-parent for Stories, parentId for Sub-tasks, explicit relationship discovery (blocks / is blocked by / relates to / duplicates), labels, components-as-labels, project milestones for fix versions, native priority and estimate fields, and Validation Journey. Rejects thin items — use this skill any time a Linear work item is created or significantly edited. |

Write Linear Work Item: $ARGUMENTS
Create or update a Linear work item — Project (for Epics), Issue (for Stories), or sub-Issue (for Sub-tasks) — with all required relationships, metadata, and quality gates. Every section below is mandatory. Thin items are rejected.
Repository name for scoped comments: basename $(git rev-parse --show-toplevel).
Configuration
This skill reads configuration from .lisa.config.json (with .lisa.config.local.json overriding per key). Required keys:
linear.workspace — Linear workspace sluglinear.teamKey — Linear team key (e.g. ENG); the team owns the destination items
If either is missing, stop and report — never invent values.
Polymorphic dispatch
Linear's data model maps Epic / Story / Sub-task to different entity types. This skill dispatches on issue_type:
issue_type | Linear entity | MCP write tool | Parent field |
|---|
Epic | Project | lisa:linear-access operation: save-project | (none — Projects are top-level within a team) |
Story / Task / Improvement | Issue | lisa:linear-access operation: save-issue | projectId (the Epic Project) |
Sub-task | sub-Issue | lisa:linear-access operation: save-issue | parentId (the Story Issue) |
Bug | Issue | lisa:linear-access operation: save-issue | projectId if part of an Epic; else top-level |
Spike | Issue | lisa:linear-access operation: save-issue | projectId if part of an Epic; else top-level |
Status workflow uses labels (status:ready, status:in-progress, status:on-dev, status:done) for portability across teams — Linear's per-team workflow state names vary, but labels are workspace-scoped and stable. Native Linear state is set to the team's default Todo state on create.
Phase 1 — Resolve Intent
Determine from $ARGUMENTS and context whether this is a CREATE or UPDATE:
- CREATE: no existing identifier provided.
- UPDATE: identifier provided (
<TEAM>-<n> for Issue, project slug + short-id for Project) — call /linear-read-issue <ref> first to load the full current state. Never overwrite without reading.
Resolve the team ID for linear.teamKey via lisa:linear-access operation: list-teams({query: <teamKey>}). Cache it.
Phase 2 — Gather Required Inputs
Required fields (stop and ask if missing — never invent values):
| Field | Required For | Notes |
|---|
team_key | CREATE | From linear.teamKey config; required for both Project and Issue creation |
issue_type | CREATE | One of: Epic, Story, Task, Bug, Spike, Sub-task, Improvement |
| Summary | CREATE, UPDATE | One line, imperative voice, under 100 chars |
| Description | CREATE, UPDATE | Multi-section markdown — see Phase 3 |
| Project parent (for Story / Task / Bug / Spike / Improvement when part of an Epic) | non-Epic, non-Sub-task in Epic context | Linear Project ID — the Epic |
| Sub-task parent | Sub-task | Linear Issue ID — the Story |
| Priority | CREATE | Native Linear priority: 0=No priority, 1=Urgent, 2=High, 3=Medium, 4=Low |
| Acceptance criteria | Story, Task, Bug, Sub-task, Improvement | Gherkin — see Phase 3 |
| Validation Journey | Runtime-behavior changes | Delegate to /linear-add-journey |
| Target backend environment | Runtime-behavior changes | dev / staging / prod; recorded in description (Phase 3). Skip only for doc/config/type-only items. |
| Sign-in account / credentials | Items that touch authenticated surfaces | Name the account (or source — 1Password item, env var, seeded fixture) and role; recorded in description. Omit when sign-in is not required. |
| Single-repo scope | Bug, Task, Sub-task | These types MUST cover one repo only. If the work crosses repos, split it before creating. Epic / Spike / Story may span repos. |
Optional but recommended: assignee, estimate (story points), labels, project milestone (fix-version equivalent), cycle.
Phase 3 — Description Quality
Linear descriptions are markdown (NOT Jira wiki markup — no h2. headings, use ## instead). The description MUST address three audiences. Reject and rewrite if any are missing.
## Context / Business Value
[Why this matters. Stakeholder-facing. Concrete user impact or business outcome.
Link to the originating Slack thread, Notion doc, incident, or customer report.]
## Technical Approach
[Developer-facing. Integration points, impacted modules, data model implications,
relevant tradeoffs. Not a full design doc — a pointer for someone picking it up.]
## Acceptance Criteria
1. Given <precondition>
When <action>
Then <observable outcome>
2. Given <precondition>
When <action>
Then <observable outcome>
## Out of Scope
[Explicit list of what this item does NOT cover. Forces scope discipline.]
## Target Backend Environment
[Required when the item changes runtime behavior. One of: dev / staging / prod.
Skip section entirely for doc-only, config-only, or type-only items.]
## Sign-in Required
[Include this section ONLY if the work touches authenticated surfaces.
Specify: the account/role to sign in as, where to get the credentials
(1Password item name, env var, seeded fixture), and any MFA/SSO notes.
Omit the section entirely when sign-in is not required.]
## Repository
[Required for Bug / Task / Sub-task. Name the single repo this item covers.
If the work spans repos, this issue type is wrong — split into per-repo
Tasks/Sub-tasks under a parent Story or Epic.]
## Validation Journey
[Delegate to /linear-add-journey if the item changes runtime behavior.
Skip only for doc-only, config-only, or type-only items.]
Rules:
- Every acceptance criterion uses Given/When/Then. No vague "should work" language.
- Every criterion is independently verifiable (UI, API, data, or performance check).
- If the item is a Bug, include reproduction steps, expected vs. actual behavior, and environment.
- If the item is a Spike, include the question being answered and the definition of done (decision doc, prototype, or findings).
- If sign-in is required, the implementer must be able to sign in from the description alone — never assume they will guess the account or hunt for credentials.
Phase 4 — Relationship Discovery (Mandatory)
Before creating or updating, find candidate relationships. Do NOT skip — this is the step agents most often omit.
4a. Project Parent (Epic-equivalent)
If the item is not an Epic and not a top-level Bug/Spike, it MUST have a parent context:
- Story / Task / Improvement → must have a
projectId (the Epic Project) set.
- Sub-task → must have a
parentId (the Story Issue) set.
If the parent is explicitly provided, use it. Otherwise:
- Search active Projects in the team:
lisa:linear-access operation: list-projects({team: <teamKey>, state: ["backlog", "planned", "started"]})
Match on keywords from the summary and description.
- If no matching Project exists, stop and ask the human to create or pick one. Do NOT orphan the item.
4b. Related Items
Relationship discovery is mandatory on every create and every update — never declare "no related work" without doing both searches below and recording their outcomes on the item.
Search 1: local git history (catches PRs / commits that touched the same area but were never linked):
git log --all --oneline --grep="<keyword>"
git log --all --oneline -- <path-or-glob>
git log --since=90.days --oneline -- <path-or-glob>
If the git search surfaces a PR or commit that relates to this work, capture the PR URL — it becomes a remote link (Phase 4c) and may also point to a sibling item worth linking.
Search 2: Linear MCP (catches open and recently-closed items):
# Open items in the same Project
lisa:linear-access operation: list-issues({project: <projectId>, state_type: ["unstarted", "started"]})
# Open items with overlapping keywords (workspace-wide)
lisa:linear-access operation: list-issues({query: "<keyword>", state_type: ["unstarted", "started"]})
# Items with shared labels
lisa:linear-access operation: list-issues({label: "<label>", updatedAt: ">-30d"})
# Recently closed items in the same Project
lisa:linear-access operation: list-issues({project: <projectId>, state_type: ["completed", "canceled"], updatedAt: ">-30d"})
Record the outcome. Add a ## Relationship Search subsection (or a comment if updating) listing the queries you ran and what they returned. If the searches yielded nothing, write that explicitly — "Searched git history for <keywords> and Linear for project=X, label=Y; no related work found." An item with zero relations and no documented search is rejected.
For each candidate, classify the relationship:
| Relation Type | When to Use |
|---|
blocks | This item must ship before the linked item can proceed |
blocked_by | The linked item must ship before this one can proceed |
relates_to | Shared context, no ordering constraint |
duplicates | This item already exists — close one as duplicate |
Linear native relations are set on the Issue via save_issue's relations field (or via a paired save_issue_relation call if available in the MCP). For Project-level (Epic) relationships, capture them in the description under ## Related Projects since Linear doesn't model relations between Projects natively.
4c. Remote Links
Identify and attach (Linear stores attachments / links on the Issue or in description body):
- GitHub PRs, branches, or commits related to this work
- Confluence pages (design docs, RFCs, runbooks)
- Dashboards (Grafana, Datadog, Sentry issue)
- Incident items (PagerDuty, Statuspage)
- Source artifacts from the originating PRD / parent Project: classify and inherit per the rules in
lisa:tracker-source-artifacts (invoke that skill if you haven't loaded the rules in this session). Enumerate the parent Project's links and inherit the ones whose domain matches this item's scope (UI → ui-design + ux-flow; backend → data; infra → ops; always inherit reference). Never assume a developer will walk up to the Project to find design context — attach it here.
If the item was generated from a PRD (by lisa:notion-to-tracker or similar) and the parent Project has no source artifacts, surface that as a smell and ask whether artifacts were missed during extraction before proceeding.
4d. Source Precedence (must appear on the item)
Source precedence rules and cross-axis conflict handling are defined in lisa:tracker-source-artifacts §3 and §4. When an item carries both design artifacts and a description, record the precedence explicitly in the description (under Technical Approach or a dedicated ## Source Precedence subsection) so the implementer doesn't silently reconcile conflicts. Cross-axis conflicts go under ## Open Questions as BLOCKER items.
For UI-touching items, include the existing-component reuse expectation per lisa:tracker-source-artifacts §7.
4e. Live Product Walkthrough Findings (UI-touching items)
If the item modifies an existing user-facing surface, a lisa:product-walkthrough should already have been run upstream. Inherit its findings under a ## Current Product subsection in the description so the implementer sees what's shipped today before changing it. If the upstream skill skipped the walkthrough but this item clearly modifies an existing surface, invoke lisa:product-walkthrough here before proceeding.
Phase 5 — Set Metadata
Before create/update, verify each field is populated where applicable:
- Labels: include
status:ready for a new leaf work unit (Bug / Task / Sub-task / Improvement with no child work) per leaf-only-lifecycle, unless build_ready: false (see the Build-ready control input below); component labels (component:<name>); status / priority labels are NOT redundant with native fields — labels exist for portability and downstream queries. A container (Epic Project / Story with sub-issues / Spike) never receives status:ready.
- Native priority field: 0–4 per Linear's scale; explicit, not "unset".
- Native estimate: per Linear's team-configured estimate scale (often 0–8 Fibonacci); skip for Epic / Spike.
- ProjectMilestone: when the team uses dated milestones, set the milestone on the Project (Epic) or on the Issue (when an Issue belongs to a milestone).
- Cycle: only if actively in a cycle.
- Assignee: leave unset if unknown rather than auto-assigning.
For Bug / Task / Sub-task, ensure the summary is prefixed with [<repo-name>].
Build-ready control input (build_ready)
build_ready is an optional write-control input (default: omitted). It governs whether a leaf work unit's status:ready label is applied on create. It never overrides leaf-only-lifecycle — a container is never stamped build-ready regardless of build_ready. "Not build-ready" is not a special state: the Issue is still created with Linear's default native Todo state; it just lacks the status:ready label the build lifecycle keys off, so a human can promote it later.
- Omitted → current behavior: a leaf work unit receives
status:ready. Preserves what every existing caller (lisa:plan, the *-to-tracker skills) relies on.
build_ready: false → create the leaf without the status:ready label, so it sits in the backlog for a human to review and promote into the queue.build_ready: true → ensure the leaf carries status:ready so lisa:intake / lisa:linear-build-intake auto-picks it up.
Phase 5.5 — Validate (Pre-write Gate)
Before any write, invoke lisa:linear-validate-issue with the full proposed spec assembled from Phases 2 / 3 / 4 / 5. Pass it as a YAML block per the lisa:linear-validate-issue schema, including runtime_behavior_change, authenticated_surface, and artifacts_attached flags so the right gates run.
The validator is the single source of truth for what makes a valid Linear work item. The same gates are used by lisa:linear-to-tracker dry-run, by lisa:linear-verify post-write, and here. Do not re-implement gate logic in this skill.
If the validator reports FAIL:
- Surface the failure list and the per-gate remediation to the user.
- Do NOT proceed to Phase 6. Fix the spec (or stop and ask the human) and re-run validation.
- Never call
lisa:linear-access operation: save-project or lisa:linear-access operation: save-issue while the validator's verdict is FAIL.
If the validator reports PASS, continue to Phase 6.
Phase 6 — Create or Update
CREATE — Epic (Project)
- Resolve any required Project labels (
prd-ticketed, etc.) via lisa:linear-access operation: list-project-labels (create via lisa:linear-access operation: create-project-label if missing).
- Call
lisa:linear-access operation: save-project with: name (summary), description (markdown), teamIds: [<teamId>], labelIds, priority (Linear Project priority is also 0–4), state (default backlog), milestones if dated.
- Capture the returned Project ID and slug — Phase 4 children need these.
- If the Project is the parent for downstream Stories, record the ID for
lisa:linear-to-tracker Phase 4 to use.
CREATE — Story / Task / Bug / Spike / Improvement (Issue with projectId)
- Resolve any required Issue labels (
component:<name>, prd-intake-feedback only if this is a sentinel issue, etc.) via lisa:linear-access operation: list-issue-labels (create via lisa:linear-access operation: create-issue-label if missing). Include status:ready in labelIds only for a leaf work unit and only when build_ready is not false (per the Build-ready control input) — omit it for a container, and for a build_ready: false leaf which then waits in the backlog for a human to promote it.
- Call
lisa:linear-access operation: save-issue with: team (teamId), title (summary), description (markdown), projectId (the Epic Project), priority (0–4), estimate, labelIds, assignee if known.
- Capture the returned identifier (e.g.
ENG-123) — Phase 4 sub-tasks need it as parentId.
- Add relationships from Phase 4b via
save_issue (relations field) or paired relation calls.
- If the item changes runtime behavior, invoke
lisa:linear-add-journey to append the Validation Journey section.
CREATE — Sub-task (Issue with parentId)
- Resolve labels as above.
- Call
lisa:linear-access operation: save-issue with: team (teamId), title ([<repo>] <summary> prefix is mandatory), description (markdown), parentId (the Story Issue ID), projectId (inherit from parent), priority, estimate, labelIds.
- Capture identifier.
- Add relationships via Phase 4b.
UPDATE
- Call
lisa:linear-access operation: save-project or lisa:linear-access operation: save-issue with only the fields being changed. Do NOT resend fields that weren't in the change set — Linear treats the call as a full overwrite of the listed fields.
- Preserve description sections you are not editing — re-read via
/linear-read-issue first, including any existing canonical managed ## Lisa Usage section unless the caller intentionally supplied an updated canonical section. Use the shared usage-accounting serializer/merge path rather than freehand edits to ledger rows.
Phase 7 — Verify
Call the lisa:linear-verify skill on the resulting item. lisa:linear-verify fetches the live item and runs lisa:linear-validate-issue against it — same gates as Phase 5.5, but applied to what Linear actually stored. If it reports failures, fix them before returning. Do not report success on an item that fails verify.
Phase 8 — Announce
Post a creation comment via lisa:linear-access operation: save-comment (on the Issue, or on a sentinel issue under the Project for Epic-level announcements) with:
[<repo>] prefix if the item is repo-scoped- Who the item is assigned to (if known)
- The relationships that were set (
blocks, blocked_by, relates_to) with Linear identifiers
- Any remote PRs attached
Skip this step only on UPDATE when no material change was made.
Rules
- Never create a non-Epic, non-top-level item without a parent context (Project for Stories, parentId for Sub-tasks).
- Never skip relationship discovery — both the git history search AND the Linear MCP search must run, and their outcomes must be recorded on the item. "None found" is acceptable only when it's documented.
- Never create a Bug, Task, or Sub-task that spans multiple repos. Split it before creating.
- Never include a runtime-behavior item without a target backend environment, and never include an authenticated-surface item without sign-in credentials in the description.
- Never invent custom field values. If the team requires a field you don't have, stop and ask.
- Never overwrite a description without reading the current version first.
- Preserve an existing canonical
## Lisa Usage section on update; never append a second usage
section or silently drop ledger rows.
- All Linear writes go through this skill so best practices are enforced uniformly. Downstream skills (e.g.
lisa:linear-create) should delegate here rather than calling the MCP write tools directly.
- The gate logic (what makes a valid item) lives in
lisa:linear-validate-issue, NOT in this skill. This skill calls the validator at Phase 5.5 (pre-write) and Phase 7 (via lisa:linear-verify post-write). When a gate needs to change, change it in lisa:linear-validate-issue — every caller picks it up automatically.
- This skill is the destination of the
lisa:tracker-write shim when tracker = "linear". Vendor-neutral callers (notion-to-tracker, confluence-to-tracker, linear-to-tracker, github-to-tracker) MUST go through lisa:tracker-write, not call this skill directly.
