What it does

Mistral Security Basics is an agent skill from jeremylongshore/tons-of-skills-marketplace. Threat-model Mistral credentials, untrusted content, model output, tools, files, and tenant access. Use when securing or reviewing an integration. Trigger with "secure Mistral", "audit Mistral prompts", or "threat model a Mistral app".

Its SKILL.md is about 880 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 Security, covering Threat modeling. 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

  • Reviewing an integration
  • With secure Mistral
  • Audit Mistral prompts
  • Threat model a Mistral app

Example prompts

  • “secure Mistral”
  • “audit Mistral prompts”
  • “threat model a Mistral app”
  • “/mistral-security-basics”

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. Map trust boundaries and classify prompts, outputs, embeddings, files, logs, and IDs.
  2. Remove credentials and privileged instructions from browser/untrusted contexts.
  3. Separate trusted policy from untrusted content and delimit retrieved text as data.
  4. Validate output structure and safety before render, storage, or tool use.
  5. Authorize tools via closed registry, schemas, least privilege, deadlines, and idempotency.
  6. Test injection, cross-tenant access, unsafe output, exfiltration, duplicates, and rotation.

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 Security Basics loads about 877 tokens when it runs, and up to ~1.1k if it reads all its reference files. Until then it costs about 65 tokens; SKILL.md has 359 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~65
When it runs · the whole SKILL.md, loaded when a task matches
~877
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 Security Boundary

Overview

Apply controls at the application boundary because model instructions do not enforce identity, tenancy, authorization, or side-effect safety. Treat user content, retrieval, files, and output as untrusted.

Prerequisites

  • A data-flow diagram covering browser, app, Mistral, stores, and tools.
  • Credential, retention, tenant, moderation, and incident policies.
  • An inventory of stateful APIs, files, retrieval stores, and actions.

Current Contract

Bearer credentials authorize provider calls but not application users. Classifiers can support policy but do not replace controls. ZDR eligibility differs between stateless and stateful products.

Authentication

Keep keys server-side and environment-scoped; rotate on exposure. Enforce user and tenant authorization before retrieval, provider calls, files, and tools.

Instructions

  1. Map trust boundaries and classify prompts, outputs, embeddings, files, logs, and IDs.
  2. Remove credentials and privileged instructions from browser/untrusted contexts.
  3. Separate trusted policy from untrusted content and delimit retrieved text as data.
  4. Validate output structure and safety before render, storage, or tool use.
  5. Authorize tools via closed registry, schemas, least privilege, deadlines, and idempotency.
  6. Test injection, cross-tenant access, unsafe output, exfiltration, duplicates, and rotation.

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 (139 more words)Show less

Approval Boundaries

Require approval for sensitive data, uploads, stateful APIs, tools, policy changes, retention, or live attack testing. Model output never grants authority.

Error Handling

  • Prompt wording cannot enforce access control.
  • Moderation success does not prove correctness or tool safety.
  • Assuming ZDR for Files, Batch, Agents, Conversations, or other stateful products is unsafe.

Output

Return assets, threats, controls, residual risks, data/API boundary, tests, owners, and rollback. Exclude live secrets and customer data.

Examples

  • Reject retrieved text asking for a system secret.
  • Require fresh app authorization before a proposed refund tool.

Validation

Run synthetic abuse cases across input, retrieval, output, rendering, and tools; confirm tenant filters and rotation independently.

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.
