competition-firmware-layout

Internal downstream skill for ctf-sandbox-orchestrator. CTF-sandbox workflow for firmware images, partition tables, boot chains, update packages, extracted filesystems, embedded configs, and device-facing trust boundaries. Use when the user asks to unpack firmware, map partition layout, inspect bootloader or init chains, recover update keys or credentials, trace config loading, or explain how a device surface reaches the decisive artifact. Use only after `$ctf-sandbox-orchestrator` has already established sandbox assumptions and routed here.

Content

72%Weight 40%Scale 1-5

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

The body is well-organized and lean with good progressive disclosure via a single clearly-signaled reference, but it lacks explicit validation checkpoints for destructive firmware-extraction operations and names no specific tooling, capping workflow clarity and limiting actionability.

Suggestions

Add an explicit verification checkpoint after extraction (e.g., confirm extracted layer hashes/sizes against recorded pristine offsets before editing) to satisfy the destructive-operation validation requirement and lift workflow clarity above 3.

Name concrete tools or commands for key steps (e.g., binwalk for container/partition identification, unsquashfs/dumpimage for extraction) to make the guidance directly executable rather than abstract.

De-duplicate the partition offset/hash/filesystem-type items that recur across Quick Start, Workflow step 1, and What To Preserve so each token earns its place.

DimensionReasoningScore

Conciseness

Lean and assumes Claude's competence — no concept explanations or padding — but the Quick Start, Workflow, and What To Preserve sections repeat overlapping items (partition offsets/hashes/filesystem types), so not every token earns its place.

4 / 5

Actionability

Concrete, specific directives ('Record offsets, sizes, hashes, mount points, and partition names', 'Separate bootloader, kernel, initramfs, rootfs...') that are actionable for an instruction-only skill, though no specific tools or commands are named.

4 / 5

Workflow Clarity

A clear 3-stage sequence (Establish Layout, Trace Boot/Update Flow, Reduce to Decisive Path) is present, but explicit validation/verification checkpoints are missing for destructive extraction operations, which caps this dimension at 3 per the rubric.

3 / 5

Progressive Disclosure

A clear overview body points to one well-signaled one-level-deep reference ('Load references/firmware-layout.md for the layout checklist, boot-chain checklist, and evidence packaging'), which exists and does not nest further.

Description

100%Weight 40%Scale 1-5

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 strong across all dimensions: it states concrete capabilities, uses natural trigger terms with synonyms, explicitly covers both what and when, and is clearly scoped as a downstream skill with minimal conflict risk.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — 'unpack firmware, map partition layout, inspect bootloader or init chains, recover update keys or credentials, trace config loading' — giving comprehensive coverage of specific capabilities rather than vague language.

5 / 5

Completeness

Explicitly answers what ('CTF-sandbox workflow for firmware images, partition tables, boot chains...') and when ('Use when the user asks to unpack firmware...') with concrete trigger phrases.

5 / 5

Trigger Term Quality

Uses natural phrases a user would say ('unpack firmware', 'partition layout', 'bootloader', 'update keys or credentials') with synonyms ('keys or credentials', 'bootloader or init chains'), matching comprehensive natural-term coverage.

5 / 5

Distinctiveness Conflict Risk

Clear niche as a downstream specialization scoped to '$ctf-sandbox-orchestrator', with specific firmware triggers and a usage guard ('Use only after... has already established sandbox assumptions') minimizing conflict risk.
