package-spec

package-spec is a skill for Claude Code, Codex from elastic/integration-skills. It costs 65 tokens per session (2,395 once invoked), scanned A, original, Apache-2.0.

A set of rules for checking Elastic integration package files, including manifests and changelogs. It defines required structures, variables, routing settings, and version changes.

In plain words
What is it for?
Use it when creating or reviewing manifest.yml and changelog.yml files, configuring inputs, or diagnosing elastic-package validation errors.
Why use it?
It helps catch package-format errors before an integration is linted, tested, or submitted.

About the project

Integration Skills is a collection of agent workflows for researching, creating, reviewing, and maintaining Elastic integration packages. Engineers use it with coding environments such as Cursor, Claude Code, and Codex to scaffold integrations, configure data streams, map fields, and run tests.

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

package-spec 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 4d 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.

Skill authority

The rules and patterns defined in this skill and its reference files are the authoritative source of truth. When examining existing integrations in the elastic/integrations repository for reference, you may encounter patterns that conflict with what is specified here -- many integrations contain legacy patterns that predate current standards. Always follow this skill over patterns observed in other integrations. If a reference integration uses a deprecated or prohibited pattern, do not copy it.

When to use

Use this skill when tasks include:

  • building or reviewing manifest.yml at root or data stream level
  • adding or validating changelog.yml entries
  • selecting the correct change type and semantic version bump
  • configuring policy templates, inputs, and variable declarations
  • debugging elastic-package lint or elastic-package check errors on manifests or changelogs
  • reviewing variable scoping across package, policy template, input, and data stream levels
  • validating Handlebars template variables against manifest declarations
  • configuring routing rules and their required manifest flags
  • determining which format_version is needed for a package's features

When NOT to use

  • Package scaffolding and directory layout (create-integration)
  • Ingest pipeline design (ingest-pipelines)
  • Field mapping and ECS compliance (ecs-field-mappings)
  • CEL programs (cel-programs)
  • Transform configuration (see review-integration skill's references/transform-guide.md)

Handoff

For package directory layout and required files, see create-integration -> references/package-layout.md. For elastic-package CLI commands and troubleshooting, see elastic-package-cli.


format_version

The format_version field in manifest.yml declares which elastic/package-spec version the package conforms to. The current standard for new packages is "3.4.2".

Use the minimum version that supports the features the package actually uses, not the latest available spec version. Bumping without needing new features:

  • forces users to run a newer Kibana than necessary
  • breaks backward compatibility for no reason
  • makes it harder to determine which features the package depends on

Changes

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.
