What it does

Mistral Core Workflow B is an agent skill from jeremylongshore/tons-of-skills-marketplace. Build Mistral embeddings, retrieval, and function-calling loops with tenant isolation and application-owned execution. Use when adding RAG or tools. Trigger with "build Mistral RAG", "use Mistral embeddings", or "add Mistral function calling".

Its SKILL.md is about 890 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; live or external Mistral actions require network access and explicit approval

It sits in AI & LLM Engineering, covering Embeddings, Structured output and tool calling and Multi-tenancy. It works with Mistral AI. 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

  • With build Mistral RAG
  • Use Mistral embeddings
  • Add Mistral function calling

Example prompts

  • “build Mistral RAG”
  • “use Mistral embeddings”
  • “add Mistral function calling”
  • “/mistral-core-workflow-b”

Requirements

  • Compatibility (from SKILL.md): Designed for Claude Code; live or external Mistral actions require network access and explicit approval
  • Pre-approved tools (allowed-tools): Read, Glob, Grep, Write, Edit

Workflow steps

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

  1. Define retrieval purpose, data class, tenant filter, deletion SLA, and evaluation set.
  2. Store embedding model, preprocessing version, and observed vector shape with each index.
  3. Retrieve with mandatory tenant filters and cap context before chat assembly.
  4. Validate each proposed tool name and argument against the closed registry and strict schema.
  5. Authorize and execute each side effect in trusted code with deadline and idempotency.
  6. Evaluate retrieval quality, access negatives, tool denial, usage, latency, and rollback.

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
    • Glob
    • Grep
    • 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

    No URLs in SKILL.md.

    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; live or external Mistral actions require network access and explicit approval

    From compatibility in the SKILL.md frontmatter.

Context cost

Mistral Core Workflow B loads about 889 tokens when it runs, and up to ~1.1k if it reads all its reference files. Until then it costs about 67 tokens; SKILL.md has 366 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~67
When it runs · the whole SKILL.md, loaded when a task matches
~889
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.1k

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.

Mistral Retrieval and Tool Execution

Overview

Keep retrieval and tool use under application control. The model may propose queries or typed arguments; trusted code owns authorization, execution, side effects, and returned evidence.

Prerequisites

  • A tenant-scoped corpus with chunking, deletion, and re-embedding policy.
  • A current embedding model selected from account evidence.
  • A closed tool registry with schemas, authorization, deadlines, and idempotency.

Current Contract

Embeddings use POST /v1/embeddings; tool calls use the current chat schema. Vector shape, model access, tool schemas, and parallel behavior must come from the selected current contracts.

Authentication

Use Bearer auth only for Mistral. Every retrieved record and proposed action must separately pass application user and tenant authorization.

Instructions

  1. Define retrieval purpose, data class, tenant filter, deletion SLA, and evaluation set.
  2. Store embedding model, preprocessing version, and observed vector shape with each index.
  3. Retrieve with mandatory tenant filters and cap context before chat assembly.
  4. Validate each proposed tool name and argument against the closed registry and strict schema.
  5. Authorize and execute each side effect in trusted code with deadline and idempotency.
  6. Evaluate retrieval quality, access negatives, tool denial, usage, latency, and rollback.

Tool Discipline

Use Read, Glob, and Grep to inspect code, locks, configuration, tests, and evidence. Use Write and Edit only for approved repository changes. Invocation alone does not authorize network calls, paid usage, uploads, stateful resources, admin mutations, deployments, or deletion.

Show full SKILL.md (135 more words)Show less

Approval Boundaries

Require approval before embedding customer data, creating an index, executing a mutation, widening corpus access, or allowing parallel actions.

Error Handling

  • Mixed-model indexes can corrupt similarity meaning.
  • Prompt instructions cannot replace tenant filters or authorization.
  • Malformed or repeated tool calls must be rejected or deduplicated, never broadened.

Output

Return corpus/tenant boundary, model/preprocessing versions, retrieval metrics, tool decisions, idempotency IDs, usage, retention, and rollback.

Examples

  • Retrieve only records authorized for one tenant and cite opaque IDs.
  • Let the model propose lookup_order; trusted code validates schema and entitlement.

Validation

Test cross-tenant denial, deletion propagation, model mismatch, empty retrieval, malformed/duplicate tools, cancellation, and mutation denial.

Resources

  • Current first-party evidence map — recheck dated sources before relying on mutable endpoints, models, limits, prices, preview status, or retention.
  • Record live account observations as environment-specific evidence, not universal Mistral guarantees.
