add-source-sourcedb-to-spannerGuide for implementing a database source connector in the v2/sourcedb-to-spanner forward migration Dataflow template.
Add Source Sourcedb To Spanner is an agent skill from GoogleCloudPlatform/DataflowTemplates. Guide for implementing a database source connector in the v2/sourcedb-to-spanner forward migration Dataflow template. Details scope boundaries, prerequisites, connector implementations, registry registrations, unit testing, and smoke testing guidelines.
Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Testing & QA, covering Unit testing. It works with Google Cloud, Google BigQuery and Java. The repository describes itself as: Cloud Dataflow Google-provided templates for solving in-Cloud data tasks. The licence is Apache-2.0.
6 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit c95daba. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
mvnFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Add Source Sourcedb To Spanner loads about 1.9k tokens when it runs. Until then it costs about 71 tokens; SKILL.md has 771 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.
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.

.claude/skills/add-source-sourcedb-to-spanner/SKILL.md (or your agent's skills folder).This skill provides a step-by-step procedure for adding support for a new database source connector to the v2/sourcedb-to-spanner forward migration template. It details prerequisites, scope boundaries, type mapping requirements, connector implementation, factory registration, unit testing, and smoke testing procedures.
[!CRITICAL] MANDATORY PREREQUISITE GATE: Before running code searches, inspecting files, or executing unit tests, you MUST verify if the user provided the inputs below. If any required input is missing, STOP IMMEDIATELY and ask the user for clarification before proceeding further.
UnifiedMappingProvider.Type.All implementation for a new source connector MUST be strictly confined to:
v2/sourcedb-to-spanner/src/main/java/com/google/cloud/teleport/v2/source/<source_type>/ISrcToSpSourceConnector (<Source>SrcToSpSourceConnector.java) or subclassing AbstractJdbcSrcToSpSourceConnector (for JDBC sources).<source_type> (e.g., <Source>ConfigDefaults.java).SourceConnectorFactory.java (v2/sourcedb-to-spanner/src/main/java/com/google/cloud/teleport/v2/source/SourceConnectorFactory.java)getSourceConnectorByDialect(), getSourceConnectorBySourceType(), and getSourceJdbcConnectorByDialect().SourceDbToSpannerOptions.java (v2/sourcedb-to-spanner/src/main/java/com/google/cloud/teleport/v2/options/SourceDbToSpannerOptions.java)String <SOURCE>_SOURCE_DIALECT = "<SOURCE_DIALECT_NAME>";) and enum registration in @TemplateParameter.Enum.v2/spanner-commonspanner-common (e.g. Constants.java / SourceConstants.java for public static final String <SOURCE>_SOURCE_TYPE = "<source_type>";).Consult the Datatype Mapping Matrix provided in the prerequisites to verify correct datatype conversion between the source database datatypes and UnifiedMappingProvider.Type / Spanner target datatypes. Ensure proper alignment for character, numeric, temporal, binary, boolean, JSON, and any other dialect-specific datatypes as specified in the mapping file.
<Source>SrcToSpSourceConnectorImplement ISrcToSpSourceConnector (or extend AbstractJdbcSrcToSpSourceConnector for JDBC sources) in com.google.cloud.teleport.v2.source.<source_type>:
UnifiedMappingProvider.Type in getTypeMapping(). Ensure all the types mentioned in the datatype mapping are covered.<Source>ConfigDefaults.java), dialect adapter, and value mappings provider in package com.google.cloud.teleport.v2.source.<source_type>.SourceDbToSpannerOptions.java and update @TemplateParameter.Enum:String <SOURCE>_SOURCE_DIALECT = "<SOURCE_DIALECT_NAME>";Constants.java / SourceConstants.java in v2/spanner-common:public static final String <SOURCE>_SOURCE_TYPE = "<source_type>";SourceConnectorFactory.java:getSourceConnectorByDialect(...)getSourceConnectorBySourceType(...)getSourceJdbcConnectorByDialect(...) (for JDBC sources)Execute Maven unit tests for the template:
mvn test -pl v2/sourcedb-to-spanner \
-Dtest=<Source>SrcToSpSourceConnectorTest,SourceConnectorFactoryTestAll unit tests must pass with BUILD SUCCESS.
[!CRITICAL] MANDATORY EXECUTION REQUIREMENT: Immediately after unit tests pass, you MUST AUTOMATICALLY PROCEED to execute live end-to-end smoke testing using the test environment details provided in the prerequisites. Do NOT stop, pause, or declare completion after unit testing without running the live smoke tests.
[!IMPORTANT] WORKER MACHINE TYPE DIRECTIVE: When submitting the Dataflow job for live smoke testing, you MUST explicitly specify a worker machine type of the correct size with at least 4 vCPUs (e.g.,
--worker-machine-type=n2-standard-4). Omitting this parameter will cause Dataflow job launch validation to fail with a machine specification policy violation.

Going by SKILL.md and its folder, Add Source Sourcedb To Spanner needs the command-line tools its instructions call (mvn).
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Add Source Sourcedb To Spanner is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.9k tokens (SKILL.md is roughly 7.4k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
