What it does
Linear Webhooks Events is an agent skill from jeremylongshore/tons-of-skills-marketplace. Implement Linear webhook verification, fast acknowledgement, deduplication, queued processing, and reconciliation. Use when receiving issue, project, cycle, customer, user, or OAuth-app events. Trigger with "handle Linear webhooks", "verify Linear signature", or "process Linear events".
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 Webhooks. 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
- Receiving issue
- OAuth-app events
- With handle Linear webhooks
- Verify Linear signature
Example prompts
- “handle Linear webhooks”
- “verify Linear signature”
- “process Linear events”
- “/linear-webhooks-events”
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.
- Select explicit resource types and team/all-public-team scope, and identify the webhook/admin owner.
- Capture the exact raw request bytes before JSON middleware and verify HMAC-SHA256 with the configured signing secret.
- Reject invalid or stale/replayed requests, deduplicate by Linear-Delivery, enqueue the verified envelope, and return 200 within five…
- Process events idempotently using action, type, entity ID, updatedFrom, organization, and webhook ID as appropriate.
- Bound retries and dead-letter handling; never assume Linear will retry beyond the documented schedule.
- Run periodic cursor-based reconciliation and test create/update/remove, duplicate, delayed, revoked-app, and secret-rotation cases.
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:
ReadGlobGrepWebFetchWriteEdit
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_KEYACCESS_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 Webhooks Events 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 78 tokens; SKILL.md has 520 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.

Linear Verified Webhook Processing
Overview
Build an ingress path that proves authenticity on raw bytes, acknowledges quickly, and makes downstream processing replay-safe.
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
- The endpoint must be public HTTPS and return HTTP 200 within five seconds; failures retry after one minute, one hour, and six hours, up to three retries.
Linear-Signatureis the hex HMAC-SHA256 of the exact raw body;Linear-Deliveryis the unique delivery UUID andLinear-Timestampis epoch milliseconds.- Only workspace admins or OAuth applications with
adminscope can create or read webhooks. - The official SDK provides
LinearWebhookClient, including raw-body signature verification and framework handlers.
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
- Select explicit resource types and team/all-public-team scope, and identify the webhook/admin owner.
- Capture the exact raw request bytes before JSON middleware and verify HMAC-SHA256 with the configured signing secret.
- Reject invalid or stale/replayed requests, deduplicate by
Linear-Delivery, enqueue the verified envelope, and return 200 within five seconds. - Process events idempotently using
action,type, entity ID,updatedFrom, organization, and webhook ID as appropriate. - Bound retries and dead-letter handling; never assume Linear will retry beyond the documented schedule.
- Run periodic cursor-based reconciliation and test create/update/remove, duplicate, delayed, revoked-app, and secret-rotation cases.

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
| Condition | Response |
|---|---|
| Signature mismatch | Return non-200, do not parse into business logic, and verify raw-body/secret selection. |
| Processing exceeds five seconds | Queue after verification and acknowledge before doing business work. |
| Duplicate delivery | Return 200 after recording the dedupe hit; do not repeat side effects. |
| Webhook disabled | Repair the endpoint, manually re-enable after approval, then reconcile the missed interval. |
Examples
Use a compact handoff that makes scope, mutation authority, and verification evidence reviewable.
Input:
scope=team; events=Issue,Comment; raw-body=true; queue=durableExpected handoff:
signature=verified; ack<5s; dedupe=delivery-id; reconciliation=enabledResources
