competition-file-parser-chain

Internal downstream skill for ctf-sandbox-orchestrator. CTF-sandbox workflow for file uploads, imports, previews, archive extraction, format conversion, parser invocation, and deserialization chains. Use when the user asks to inspect an upload or import path, trace archive extraction, preview or converter behavior, explain how a file reaches a parser or deserializer, or connect one uploaded artifact to the decisive backend effect. Use only after `$ctf-sandbox-orchestrator` has already established sandbox assumptions and routed here.

Quality

Content

87%Weight 40%Scale 1-3

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is concise, actionable, and well-structured with a clean one-level reference split. Its only weakness is implicit rather than explicit validation checkpoints in the workflow.

Suggestions

Add an explicit verification checkpoint in the workflow (e.g., 'Before reporting, confirm the reduced chain reproduces the decisive branch; if it does not, re-expand the boundaries and retry') to reach score-3 workflow clarity.

Make the 'record before mutating' guard a distinct numbered checkpoint with a pass/fail condition rather than a soft ordering note.

De-duplicate the downstream-routing guard, which already appears in the description and is restated twice in the body intro, to tighten conciseness further.

DimensionReasoningScore

Conciseness

The body is lean and assumes Claude's competence — it never explains what a parser, archive, or deserializer is, and every section delivers directive content rather than padding.

3 / 3

Actionability

As an instruction-only skill it gives concrete, specific guidance ('Record filenames, MIME guesses, extensions, temp paths, and parser choices'; ordered chain mapping), so absent code is not penalized per the scoring notes.

3 / 3

Workflow Clarity

Steps are clearly sequenced (Quick Start 1-5, Workflow 1-3) but checkpoints are implicit ('before mutating anything', 'reproduce the smallest chain') rather than the explicit validate->fix->retry loops in the score-3 anchor.

2 / 3

Progressive Disclosure

A single real, one-level-deep reference (`references/file-parser-chain.md`) is clearly signaled under 'Read This Reference' with the checklist split out, matching the bundle structure on disk.

Description

100%Weight 40%Scale 1-3

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is specific, trigger-rich, complete, and clearly scoped as a downstream specialization with an explicit routing guard. It is a strong, low-conflict description.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — 'file uploads, imports, previews, archive extraction, format conversion, parser invocation, and deserialization chains' — in third-person voice, matching the score-3 anchor.

3 / 3

Completeness

Clearly states both what (the CTF-sandbox file-processing workflow) and when (explicit 'Use when...' trigger plus a downstream gating condition), satisfying both halves of the rubric.

3 / 3

Trigger Term Quality

The 'Use when the user asks to inspect an upload or import path, trace archive extraction, preview or converter behavior, explain how a file reaches a parser or deserializer...' clause gives natural phrasings a user would actually say.

3 / 3

Distinctiveness Conflict Risk

The narrow file-parser-chain niche and the 'Use only after `$ctf-sandbox-orchestrator`' guard make it clearly distinguishable and unlikely to trigger for the wrong skill.
