trivial_pr: the PR was judged by the LLM as too trivial (e.g. only config, docs, or dependency-version changes) and unsuitable as a SWE task.

validation: validation failed after task generation (the NOP agent did not return reward=0, or the ORACLE agent did not return reward=1).

infra_error: infrastructure error (Docker build failure, network timeout, insufficient disk space, etc.).

timeout: processing timed out (per-PR total timeout or Claude Code session timeout).

workflow_error: workflow error (PR metadata fetch failure, worktree creation failure, patch generation failure, etc.).

Metric Definitions

click to expand

Difficulty score (difficulty_score)

Reads each valid task directory's solution/fix.patch, tests/, and instruction.md, scored statically with zero API calls by src/swegen/scoring.py.

The current formula uses log-scale continuous scoring to avoid mid-sized patches becoming hard too early. Weights: patch_scope 38%, logic_complexity 32%, context_breadth 15%, test_complexity 10%, instruction_complexity 5%.

Label thresholds: easy <= 4.0, medium <= 7.0, hard > 7.0.

Tag generation and display

tags are not computed live by the dashboard; they are generated by the LLM from PR information when swegen builds the task, and written to [metadata].tags in task.toml.

The prompt asks for tags in four parts: programming language, project layer/domain, framework/library or specific topic, and a domain-independent bug class (e.g. missing-fallback, incomplete-validation). The dashboard reads existing task.toml files, counts each language's tag occurrences and share, and treats the 4th tag as the bug class for the Bug-Class panels below.

fix.patch statistics

Patch stats come from each valid task's solution/fix.patch, filtering code files by language extension, consistent with the code-only stats in upload_march_swe_to_hf.py.

Avg fix.patch lines counts added/removed lines in code-file diffs; Avg fix.patch hunks counts @@ hunks; Avg fix.patch files counts the code files involved.

Global Top Bug Classes

Bug class is the 4th tag in task.toml -> [metadata].tags: a domain-independent label describing the defect mechanism (e.g. missing-fallback, incomplete-validation, off-by-one-error). Generated by the LLM during swegen create and backfilled into legacy 3-tag tasks via swegen backfill-tags.

Top bug classes per mainstream language. Counts are over tasks whose task.toml already carries a 4-tag entry; tasks still on the legacy 3-tag schema do not contribute until the backfill catches up.
