ase-arch-discover is a skill for Claude Code from rse/ase. It costs 26 tokens per session (3,170 once invoked), scanned A, original, Apache-2.0.

A tool for finding third-party libraries and frameworks that add needed functions to a software project.

In plain words
What is it for?
Use it to discover components for a particular technology stack and functionality, with an interactive choice when the request is unclear.
Why use it?
It helps when you know what the project should do but do not know which existing components can provide it.

SkillSpector: 1 finding, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • high Tool Misuse · line 160
    Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).
    Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ase-arch-discover scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

$ARGUMENTS

2.  If <functionality/> is not clear, not precise, or not specific
    enough, let the *user interactively choose* the intended
    functionality.

    In the following, you *MUST* *NOT* use your built-in
    <user-dialog-tool/> tool! Instead, you *MUST* just show a
    custom dialog according to the expanded `custom-dialog`
    definition. You *MUST* closely follow this definition:

    <expand name="custom-dialog" arg1="--no-other">
        Functionality: Which functionality should the components provide?
        <answer-1/>: (grounded candidate functionality 1)
        <answer-2/>: (grounded candidate functionality 2)
        <answer-3/>: (grounded candidate functionality 3)
        <answer-4/>: (grounded candidate functionality 4)
    </expand>

    Then use the <result/> and its corresponding grounded candidate
    functionality to adjust <functionality/> accordingly.

3.  Display the determined final functionality with just the following
    <template/>:

    <template>
    <ase-tpl-bullet-normal/> **FUNCTIONALITY**: <functionality/>
    </template>
</step>

2. 1. Determine the used technology stack:

    1.  If a file `package.json` is found in the top-level directory
        of the project and contains an entry `typescript` under `dependencies`
        or `devDependencies`, then <stack>TypeScript</stack>.

    2.  Else, if a file `package.json` is found in the top-level directory
        of the project, then <stack>JavaScript</stack>.

    3.  Else, if a file `build.gradle.kts` is found in the top-level directory and
        is applying `kotlin`, `org.jetbrains.kotlin.jvm`, `kotlin-android`,
        or `kotlin-multiplatform` plugins, then <stack>Kotlin</stack>.

    4.  Else, if a file `build.gradle` is found in the top-level directory and
        is applying `kotlin`, `org.jetbrains.kotlin.jvm`, `kotlin-android`,
        or `kotlin-multiplatform` plugins, then <stack>Kotlin</stack>.

    5.  Else, if a file `pom.xml` is found in the top-level directory and
        contains `kotlin-maven-plugin` or `kotlin-stdlib` dependencies, then
        <stack>Kotlin</stack>.

    6.  Else, if a file `pom.xml`, `build.gradle`, or `build.gradle.kts` is found
        in the top-level directory of the project, then <stack>Java</stack>.

    7.  Else, use <stack>Unknown</stack>.

2.  Display the determined final technology stack with just the
    following <template/>:

    <template>
    <ase-tpl-bullet-normal/> **TECHNOLOGY STACK**: <stack/>
    </template>
</step>

3. 1. If is "Unknown", the technology stack could not be determined and no component discovery backend is available. Inform the user with just the following and then STOP the entire flow (do not perform any further steps):

    <template>
    <ase-tpl-bullet-normal/> **RESULT**: technology stack could not be determined -- component discovery is only supported for JavaScript, TypeScript, Java, and Kotlin projects.
    </template>

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
