What it does

Mistral Core Workflow A is an agent skill from jeremylongshore/tons-of-skills-marketplace. Implement governed Mistral chat, streaming, and structured-output requests with schema validation and model evidence. Use when building text-generation workflows. Trigger with "build Mistral chat", "stream a Mistral response", or "return structured Mistral output".

Its SKILL.md is about 900 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 Structured output and tool calling and Forms and validation. 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

  • Building text-generation workflows
  • With build Mistral chat
  • Stream a Mistral response
  • Return structured Mistral output

Example prompts

  • “build Mistral chat”
  • “stream a Mistral response”
  • “return structured Mistral output”
  • “/mistral-core-workflow-a”

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. Translate the requirement into text, stream, or structured mode and document why.
  2. Resolve a permitted model dynamically and pin reproducibility parameters.
  3. Assemble trusted policy and bounded user content; keep untrusted text out of control instructions.
  4. For streams, validate ordering, cancellation, terminal state, partial output, and usage.
  5. For structured output, parse and validate the application schema; reject prose fallback.
  6. Record request identity, latency, finish state, usage, validation, and retention class.

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 A loads about 902 tokens when it runs, and up to ~1.1k if it reads all its reference files. Until then it costs about 72 tokens; SKILL.md has 370 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~72
When it runs · the whole SKILL.md, loaded when a task matches
~902
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 Chat, Streaming, and Structured Output

Overview

Select the simplest chat mode satisfying the product contract. Treat non-streaming text, streaming events, and structured output as different state machines with shared safety and usage controls.

Prerequisites

  • A model policy based on current account-visible evidence.
  • A bounded prompt/data class and maximum output policy.
  • A parser, schema validator, cancellation path, and synthetic fixtures.

Current Contract

Chat uses POST /v1/chat/completions. Streaming and response-format options are endpoint capabilities, not guarantees for every model; validate the current schema and selected model.

Authentication

Use server-side Bearer auth through the approved adapter. Never forward credentials or raw headers to users, tools, or browser code.

Instructions

  1. Translate the requirement into text, stream, or structured mode and document why.
  2. Resolve a permitted model dynamically and pin reproducibility parameters.
  3. Assemble trusted policy and bounded user content; keep untrusted text out of control instructions.
  4. For streams, validate ordering, cancellation, terminal state, partial output, and usage.
  5. For structured output, parse and validate the application schema; reject prose fallback.
  6. Record request identity, latency, finish state, usage, validation, and retention class.

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 (147 more words)Show less

Approval Boundaries

Require approval for live requests, new data classes, higher output, model fallback, or retention. Returned text is data, not executable authority.

Error Handling

  • Transport success can still fail schema or safety validation.
  • Interrupted streams require an explicit partial-output policy.
  • Unsupported option/model combinations must fail closed.

Output

Return mode, model evidence, endpoint, schema version, terminal and validation state, latency, usage, retention, and rollback. Mark every rejected or partial response explicitly.

Examples

  • Stream synthetic content while proving cancellation has no business side effect.
  • Require known JSON fields and reject unvalidated free-form fallback.

Validation

Test malformed output, missing terminal events, cancellation, blocked content, capability drift, and usage capture. Prove that no failure path silently returns unvalidated content.

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.
