What it does

Salesforce Local Dev Loop is an agent skill from jeremylongshore/tons-of-skills-marketplace. Build a repeatable Salesforce DX development loop using source format, synthetic tests, and an authorized scratch org or sandbox. Use when changing metadata or integration code. Trigger with "build a Salesforce dev loop".

Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: Designed for Claude Code; org creation, metadata deployment, and test-data loading require Dev Hub and administrator authorization

It sits in Sales & Support, covering CRM management. It works with Salesforce. 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

  • Changing metadata
  • Integration code
  • With build a Salesforce dev loop

Example prompts

  • “build a Salesforce dev loop”
  • “/salesforce-local-dev-loop”

Requirements

  • Compatibility (from SKILL.md): Designed for Claude Code; org creation, metadata deployment, and test-data loading require Dev Hub and administrator authorization
  • Pre-approved tools (allowed-tools): Read, Glob, Grep, WebFetch, Write, Edit

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. Inspect project configuration, package directories, metadata ownership, API versions, hooks, and current CLI pin.
  2. Choose a scratch org or development sandbox based on feature fidelity, data need, namespace, and lifecycle constraints.
  3. Create synthetic fixtures and local contract tests that require no live org or secret.
  4. Run formatting, static analysis, unit tests, schema checks, and metadata dependency checks locally.
  5. With approval, create or authenticate the development org and deploy only the bounded source set.
  6. Run Apex, Flow, Lightning, and integration tests applicable to the change; capture aggregate results and IDs only.
  7. Delete synthetic data, close or expire temporary orgs, revoke temporary access, and record reproducible commands.

What it can do on your machine

Read from SKILL.md and the folder at commit 80f86df. 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:

    • Read
    • Glob
    • Grep
    • WebFetch
    • Write
    • Edit

    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):

    • developer.salesforce.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Designed for Claude Code; org creation, metadata deployment, and test-data loading require Dev Hub and administrator authorization

    From compatibility in the SKILL.md frontmatter.

Context cost

Salesforce Local Dev Loop loads about 1k tokens when it runs. Until then it costs about 62 tokens; SKILL.md has 412 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~62
When it runs · the whole SKILL.md, loaded when a task matches
~1k

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.

Salesforce DX Local Development Loop

Overview

Create a source-driven loop that separates static and synthetic checks from explicitly authorized org validation and leaves no unmanaged test data.

Prerequisites

  • A Salesforce DX project or an approved migration plan to source format
  • An authorized Dev Hub and scratch-org definition, or a dedicated development sandbox
  • Synthetic fixtures, test owner, cleanup policy, and current Salesforce CLI contract

Tool Discipline

Use Read, Glob, and Grep to inspect approved repository and evidence files, WebFetch to re-check current first-party Salesforce documentation, and Write or Edit only for secretless plans, fixtures, configuration, and redacted receipts.

Current Contract

Salesforce DX supports source-driven development and scratch orgs configured through project definitions; org availability, features, limits, duration, namespaces, and sandbox alternatives depend on the customer environment.

Authentication

Use a named CLI alias backed by the approved OAuth path. Never commit authorization files, access tokens, private keys, usernames, org IDs, or generated user passwords.

Instructions

  1. Inspect project configuration, package directories, metadata ownership, API versions, hooks, and current CLI pin.
  2. Choose a scratch org or development sandbox based on feature fidelity, data need, namespace, and lifecycle constraints.
  3. Create synthetic fixtures and local contract tests that require no live org or secret.
  4. Run formatting, static analysis, unit tests, schema checks, and metadata dependency checks locally.
  5. With approval, create or authenticate the development org and deploy only the bounded source set.
  6. Run Apex, Flow, Lightning, and integration tests applicable to the change; capture aggregate results and IDs only.
  7. Delete synthetic data, close or expire temporary orgs, revoke temporary access, and record reproducible commands.

Approval Boundaries

Do not create orgs, enable features, deploy metadata, load data, or change remote configuration without Dev Hub, admin, and component-owner approval.

Output

Return the environment decision, pinned toolchain, source and fixture map, local and org test results, cleanup receipt, and remaining fidelity gaps.

Error Handling

ConditionResponse
Scratch-org feature does not match productionUse an approved sandbox or revise the definition; do not weaken production metadata.
Deployment reports missing dependenciesAdd the dependency explicitly or reduce the source set before retrying.
Test data cannot be proven syntheticStop and replace it before local export or CI use.

Example

A redacted completion receipt might look like this:

text
project=sfdx; target=scratch-org; fixtures=synthetic; static=pass; deploy=validated; apex=pass; cleanup=complete

Resources

Next Steps

Run the workflow first in the lowest-risk authorized org and preserve its redacted receipt. Schedule a review against the next Salesforce seasonal release and the customer change calendar.
