create-trigger

A tool for creating Harness triggers, which automatically start a software pipeline when an event occurs. A pipeline is an automated sequence that builds, tests, or deploys software.

In plain words
What is it for?
Use it to create webhook, scheduled, artifact, or manifest triggers, add filters such as branches or payload conditions, and verify Git webhook registration.
Why use it?
It turns requirements such as a Git event, schedule, new registry artifact, or Helm change into a trigger configuration and creates it in Harness.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

create-trigger scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

100% identical to create-trigger — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Create Trigger

Generate Harness Trigger YAML and push to Harness via MCP.

Instructions

  1. Identify trigger type - Webhook (Git events), Scheduled (cron), Artifact (registry updates), or Manifest (Helm chart updates)
  2. Configure conditions - Branch filters, payload conditions, cron expression, or artifact path
  3. Generate YAML using the templates below, referencing the target pipeline
  4. Create via MCP using harness_create with resource_type trigger
  5. Verify webhook registration - For webhook triggers, confirm the webhook is registered in the Git provider

Trigger Types

  • Webhook - GitHub, GitLab, Bitbucket, Azure Repos, Custom
  • Scheduled - Cron-based scheduling
  • Artifact - Docker Hub, ECR, GCR, ACR, Nexus
  • Manifest - Helm chart updates

GitHub Event Types

  • Push - Code pushed to branch
  • PullRequest - PR events (Open, Close, Reopen, Synchronize, Edit)
  • IssueComment - PR comments (Create, Edit, Delete)
  • Release - Release events (Create, Publish, Edit)

Webhook Trigger (GitLab)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
