What it does

Windsurf Core Workflow B is an agent skill from jeremylongshore/tons-of-skills-marketplace. Choose and create Devin Desktop customizations: Rules, AGENTS.md, Workflows, Skills, and Memories. Use when making Cascade behavior reusable or deciding how a procedure should activate. Trigger with "windsurf workflow", "Cascade skill", "windsurf rule", "AGENTS.md", or "Cascade memory".

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

It sits in Agent Workflows, covering Agent instruction files. 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

  • Making Cascade behavior reusable
  • Deciding how a procedure should activate
  • With windsurf workflow

Example prompts

  • “windsurf workflow”
  • “Cascade skill”
  • “windsurf rule”
  • “/windsurf-core-workflow-b”

Requirements

  • Compatibility (from SKILL.md): Designed for Claude Code
  • Pre-approved tools (allowed-tools): Read, Write, Edit, Bash(npm:*), Grep

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Choose the mechanism
  2. Create a Rule or AGENTS.md
  3. Create a Workflow
  4. Create a Skill
  5. Verify activation

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:

    • Read
    • Write
    • Edit
    • Bash(npm:*)
    • Grep

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).

    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):

    • docs.devin.ai

    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

    From compatibility in the SKILL.md frontmatter.

Context cost

Windsurf Core Workflow B loads about 1.3k tokens when it runs, and up to ~1.4k if it reads all its reference files. Until then it costs about 78 tokens; SKILL.md has 481 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~78
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.4k

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.

Devin Desktop Customizations

Overview

Devin Desktop is the current name for Windsurf. Select the smallest customization that matches the task instead of treating Workflows and Memories as interchangeable automation.

Prerequisites

  • Devin Desktop with Cascade enabled
  • A version-controlled workspace for shared customizations
  • A concrete behavior or procedure to encode

Authentication

Rules, AGENTS.md, Workflows, and Skills require no separate authentication. MCP-backed steps use provider OAuth or environment-backed secrets; never embed tokens in customization files.

Tool Use

  • Use Read to inspect only the repository files and configuration needed for the request.
  • Use Grep to locate relevant settings, rules, logs, or code without broad collection.
  • Use Write only for a new artifact the user requested; never write credentials or unreviewed production configuration.
  • Use Edit for bounded, reviewable changes and preserve unrelated user work.
  • Use only the command-scoped Bash entries declared in frontmatter, with non-destructive checks before mutations.

Instructions

Step 1: Choose the mechanism
MechanismActivationUse for
Rulealways_on, glob, model_decision, or manualShort behavioral constraints
AGENTS.mdRoot always-on; subdirectory location-scopedRepository conventions without frontmatter
WorkflowManual only through /workflow-nameRepeatable prompt sequences
SkillDynamic model invocation or @mentionMulti-step procedures with supporting files
MemoryAutomatic local retrievalEphemeral facts; not durable team knowledge

Prefer .devin/rules/*.md for Rules. Legacy .windsurf/rules/ remains a fallback. Keep durable team knowledge in version control rather than relying on local auto-generated Memories.

Step 2: Create a Rule or AGENTS.md

Use a Rule for controlled activation:

markdown
---
trigger: glob
globs: "src/api/**/*.ts"
---

# API constraints
- Validate external input at the route boundary.
- Return the repository's standard error envelope.

Use a root or directory-level AGENTS.md when location alone should determine scope.

Step 3: Create a Workflow

Save manual procedures under .windsurf/workflows/<name>.md, within the documented 12,000-character limit:

markdown
# Review current pull request

1. Read the diff against the target branch.
2. Run the repository's required tests.
3. Report correctness, security, and regression findings with file locations.
4. Stop and ask for clarification when a finding cannot be resolved safely.

Invoke it explicitly as /review-current-pr. Workflows are Cascade-specific and are not automatically selected.

Show full SKILL.md (205 more words)Show less
Step 4: Create a Skill

Use .windsurf/skills/<name>/SKILL.md when the procedure needs scripts, templates, or reference files. Devin Desktop also discovers cross-agent skills under .agents/skills/; use that location when portability is intentional.

Step 5: Verify activation

Test one matching and one non-matching request. Confirm a Rule's trigger, a Workflow's slash command, or a Skill's dynamic/explicit invocation. Record the file location and visible outcome.

Output

Create the selected customization in its documented location, explain why it is a Rule, AGENTS.md, Workflow, Skill, or Memory, state its activation behavior and scope, and provide matching and non-matching verification evidence.

Error Handling

IssueResponse
Workflow is not listedConfirm .windsurf/workflows/*.md, discovery scope, and character limit
Skill is not invokedImprove name/description, then test with @mention
Rule applies too broadlyReplace always_on with a narrower glob, model decision, or AGENTS.md scope
Memory is staleRemove it through Customizations and encode durable knowledge as a Rule

Examples

"Use a Workflow for a release checklist that a human must start; use a Skill for test-and-fix guidance Cascade should select automatically with bundled scripts."

Resources

Use windsurf-policy-guardrails when the customization must be enforced through Hooks, CI, repository protection, or an organization-wide administrative policy.
