deep-analysis

Depth-first RE investigation loop for a single binary or function cluster: decompile→rename→retype→comment→re-read, with context-rot guards and on-task checks. Use when triage has already identified the interesting area and the goal is full understanding: what does function X do, identify cryptographic primitives, locate C2 protocol, recover data structures. Triggers on: 'deep analysis', 'understand function', 'recover struct', 'crypto identification', 'C2 protocol', 'reverse this binary fully', 'what does this function do'.

Quality

Content

88%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 a highly actionable, well-sequenced RE workflow with concrete tool calls, validation checkpoints, and a completion gate. It is efficient and assumes Claude's competence, with only minor trim and structure-split opportunities.

Suggestions

Move the crypto constant reference table and the inline capa/pefile entropy Python scripts into a references/ file (e.g. crypto-constants.md) and link to it, keeping the body leaner.

Tighten the per-question strategies so they reference the core 2a-2e loop rather than restating its steps.

Consider extracting the Tools table into a separate reference file or condensing it, since the same tool calls are already demonstrated inline.

DimensionReasoningScore

Conciseness

Mostly lean and assumes Claude's RE knowledge without explaining basics, but the crypto constant table and inline capa/entropy Python scripts are somewhat long and the per-question strategies lightly repeat the core loop; minor trim opportunities remain.

4 / 5

Actionability

Fully executable guidance throughout: concrete Ghidra MCP calls with realistic arguments (ghidra_batch_rename, ghidra_retype, ghidra_set_comment) and runnable shell/Python for crypto-constant grepping, capa, and pefile entropy scanning.

5 / 5

Workflow Clarity

Clear numbered loop (2a-2e) with an explicit 'On-Task Check (every 3-5 tool calls)' validation checkpoint, context-rot prevention rules, re-read feedback loop, and a concrete completion gate checklist.

5 / 5

Progressive Disclosure

No bundle files exist, so this scores against the in-body structure, which is well-organized into clearly headed sections; the crypto constant table, inline entropy script, and tools table could arguably be split into reference files, leaving minor organization gaps.

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 exemplary: it states concrete capabilities, provides comprehensive natural trigger phrases, and explicitly covers both what the skill does and when to use it. It is clearly distinguishable from sibling triage skills.

DimensionReasoningScore

Specificity

Lists multiple concrete actions ('decompile→rename→retype→comment→re-read', 'identify cryptographic primitives', 'locate C2 protocol', 'recover data structures') with comprehensive coverage of the skill's capabilities.

5 / 5

Completeness

Explicitly answers both 'what' (the depth-first RE investigation loop) and 'when' via a clear 'Use when...' clause plus a concrete 'Triggers on:' list of phrases.

5 / 5

Trigger Term Quality

Comprehensive coverage of natural trigger phrases a user would actually say, including synonyms and quoted forms ('deep analysis', 'understand function', 'recover struct', 'crypto identification', 'C2 protocol', 'reverse this binary fully', 'what does this function do').

5 / 5

Distinctiveness Conflict Risk

Occupies a clear niche (depth-first RE after triage), explicitly distinguishes itself from breadth-first triage, and uses distinct triggers with minimal overlap risk.
