transformer-lens-interpretability

Provides guidance for mechanistic interpretability research using TransformerLens to inspect and manipulate transformer internals via HookPoints and activation caching. Use when reverse-engineering model algorithms, studying attention patterns, or performing activation patching experiments.

Quality

Content

75%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.

A well-structured, highly actionable skill body with executable code for three core interpretability workflows and clearly signaled, verified reference files. The main improvements are completing the stubbed final steps of Workflows 1 and 2, adding validation checkpoints, and removing marketing prose and duplicated API tables.

Suggestions

Replace the stub comments ending Workflow 1 ('# 5. Visualize results') and Workflow 2 ('# 5. Identify top contributing heads') with executable code, or point explicitly to the section of references/tutorials.md that covers them.

Add explicit validation checkpoints to the workflows (e.g., verify the baseline logit difference is positive and of expected magnitude before running the full patching sweep) so failures are caught early rather than after expensive loops.

Trim non-actionable prose (creator attribution, GitHub star count, Version Notes) and remove the dangling papers.md link in references/README.md, since that file does not exist in the bundle.

DimensionReasoningScore

Conciseness

The body is mostly library-specific and token-efficient (cache-key tables, hook gotchas, executable snippets), but includes trimmable padding such as creator attribution, the '(2,900+ stars)' note, and a Version Notes section, plus API tables that duplicate references/api.md.

4 / 5

Actionability

Nearly all guidance is concrete, copy-paste-ready code, but two workflows terminate in stub comments ('# 5. Visualize results (layer x position heatmap)', '# 5. Identify top contributing heads...') instead of executable code, leaving minor gaps.

4 / 5

Workflow Clarity

The three workflows are clearly sequenced with numbered steps and end-of-workflow checklists, but there are no explicit validation checkpoints or feedback loops (e.g., sanity-checking the baseline logit difference before proceeding with patching).

4 / 5

Progressive Disclosure

The Reference Documentation table clearly signals the three one-level-deep reference files, all of which exist and contain substantial content; however, references/README.md links a papers.md that does not exist, and some API detail inlined in SKILL.md duplicates references/api.md.

Description

87%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.

A strong description with an explicit and specific 'Use when' clause paired with a clear statement of capability. Third-person voice is used correctly. It would benefit from a broader set of natural trigger synonyms (circuit analysis, causal tracing, logit lens) and a more action-oriented opening phrase.

DimensionReasoningScore

Specificity

The description lists several concrete actions ('inspect and manipulate transformer internals via HookPoints and activation caching') but opens with the generic phrase 'Provides guidance for mechanistic interpretability research', leaving minor gaps versus a comprehensive action inventory.

4 / 5

Completeness

It explicitly answers both 'what' (inspect and manipulate transformer internals via HookPoints and activation caching) and 'when' with an explicit 'Use when' clause containing three concrete trigger phrases, matching the top anchor exactly.

5 / 5

Trigger Term Quality

Natural user phrasings like 'reverse-engineering model algorithms', 'studying attention patterns', and 'activation patching' are present, but common synonyms such as 'circuit analysis', 'causal tracing', or 'logit lens' are missing.

4 / 5

Distinctiveness Conflict Risk

TransformerLens is named specifically with its distinctive mechanisms (HookPoints, activation patching), creating a clear niche with minimal conflict risk against generic ML-training skills.
