rr-debugger

Deterministic debugging with rr record-replay. Use when debugging crashes, ASAN faults, or when reverse execution is needed. Provides reverse-next, reverse-step, reverse-continue commands and crash trace extraction.

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 genuine reference script, but the crash-trace workflows rely on '...' placeholders and lack explicit checkpoints, capping workflow clarity.

Suggestions

Replace the 'next\nnext\n...' placeholders with a concrete loop instruction (e.g., 'continue stepping with next until you reach the faulting line') so the workflow is fully executable.

Add an explicit checkpoint after going back in time, such as confirming the current source location with 'list' or 'frame' before stepping forward to reconstruct the crash path.

Tighten the opening line, which restates the description's 'deterministic record-replay debugging with full reverse execution capabilities', to avoid redundant context.

DimensionReasoningScore

Conciseness

The body is lean: mostly command lists with brief annotations and executable code blocks, assuming Claude's competence without explaining gdb or rr concepts. The only mild redundancy is the opening restatement of the description.

3 / 3

Actionability

Provides copy-paste-ready bash/gdb commands with concrete examples like 'reverse-next 100', 'bt', 'break *$pc', and 'x/10xb <addr>' rather than abstract direction.

3 / 3

Workflow Clarity

The record→replay→reverse→step-forward sequence is clear, but the 'next\nnext\n...' placeholders are incomplete rather than fully executable, and no explicit validation/checkpoint confirms the trace was captured before proceeding.

2 / 3

Progressive Disclosure

Well-organized single-purpose content split into clear sections with a single one-level-deep reference to a real file (scripts/crash_trace.py), matching the simple-skill anchor.

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 concise, specific, and uses third person with explicit trigger guidance covering what and when. It is a strong example of a well-formed skill description.

DimensionReasoningScore

Specificity

Lists multiple concrete actions: 'reverse-next, reverse-step, reverse-continue commands and crash trace extraction', plus 'Deterministic debugging with rr record-replay', matching the multiple-specific-actions anchor.

3 / 3

Completeness

Explicitly answers both what ('Deterministic debugging with rr record-replay... Provides reverse-... commands and crash trace extraction') and when ('Use when debugging crashes, ASAN faults, or when reverse execution is needed').

3 / 3

Trigger Term Quality

'Use when debugging crashes, ASAN faults, or when reverse execution is needed' supplies natural terms users would actually say (crashes, ASAN faults, reverse execution).

3 / 3

Distinctiveness Conflict Risk

The rr deterministic-replay niche with ASAN/reverse-execution triggers is clearly distinct and unlikely to fire for unrelated skills.
