When and how to reach for the companion detectors -- bandit (Python SAST) and trivy (deps + secrets + IaC misconfig) -- alongside the core semgrep/CodeQL/osv/trufflehog toolchain

  • Tasks that involve Static analysis and SAST
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Tasks that involve Secrets management

What it does

Detection Breadth is an agent skill from deonmenezes/mantishack. When and how to reach for the companion detectors -- bandit (Python SAST) and trivy (deps + secrets + IaC misconfig) -- alongside the core semgrep/CodeQL/osv/trufflehog toolchain

Its SKILL.md is about 510 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Security, covering Static analysis and SAST and Secrets management. It works with Trivy, Python and Semgrep. The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Static analysis and SAST
  • Tasks that involve Secrets management

Example prompts

  • “/detection-breadth”

Requirements

  • Python 3

What it can do on your machine

Read from SKILL.md and the folder at commit c3a2e68. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    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.

Context cost

Detection Breadth loads about 510 tokens when it runs. Until then it costs about 49 tokens; SKILL.md has 242 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~49
When it runs · the whole SKILL.md, loaded when a task matches
~510

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.

description
When and how to reach for the companion detectors -- bandit (Python SAST) and trivy (deps + secrets + IaC misconfig) -- alongside the core semgrep/CodeQL/osv/trufflehog toolchain

The core Detect toolchain is semgrep (broad SAST), CodeQL (dataflow SAST), osv-scanner (SCA), trufflehog (secrets), and program-analysis (AST/taint/SMT). Two companion servers widen coverage; reach for them deliberately, not reflexively.

  • bandit_scan (mantis_bandit): Python-specific SAST. Use it on Python targets in addition to semgrep -- bandit encodes Python-idiom checks (e.g. subprocess with shell=True, weak crypto, yaml.load, flask debug) that a generic ruleset can under-cover. Every hit is a candidate; bandit's own severity/confidence describe rule confidence, not demonstrated impact, so do not report them as final severity. Default confidence to low for full recall on a first sweep.
  • trivy_scan (mantis_trivy): composition analysis in one pass -- vulnerable dependencies, embedded secrets, and IaC (Dockerfile/Terraform/k8s) misconfigurations. Use it to add container/IaC coverage that osv-scanner (deps only) and trufflehog (secrets only) don't reach. A vulnerable dependency being present does not mean its vulnerable code path is reachable -- that's a separate question for the reachability stage. Secret values are never returned, only rule/line references.

Both degrade gracefully: if the underlying binary isn't installed they report available: false. When that happens, say so explicitly rather than claiming coverage you didn't get, and fall back to the core toolchain. Do not double-count: if trivy and osv-scanner both flag the same advisory for the same package, it's one candidate, not two.

Every result from either tool is a candidate in the findings lifecycle -- register it via mantis_findings finding_create, then trace reachability and attacker-simulate before it can become confirmed (see the mantis-pipeline and findings-spine skills).
