Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.00380 |
| Opus 5 | $0.00000 | $0.00190 |
| Sonnet 5 | $0.00000 | $0.00076 |
| Haiku 4.5 | $0.00000 | $0.00038 |
Grade A, and why
evo-python-build-fixer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
evo-python-build-fixer
Description
Diagnoses and fixes Python repository build failures. Analyzes source code for import errors, syntax errors, missing dependencies, and configuration issues. Generates standard unified diff patches and applies them.
When to Use
- When a Python project fails to build or pass tests
- When you need to diagnose import errors, missing optional dependencies
- When you need to create and apply git-compatible patches
Common Patterns
Pattern 1: Optional Dependency Import Guard
When a module imports from an optional dependency unconditionally, wrap it in try/except:
try:
from .optional_module import OptionalClass
except ImportError:
OptionalClass = None
Pattern 2: Conditional Export in init.py
When init.py exports symbols from optional modules:
try:
from .langchain_handler import Handler
except ImportError:
pass # langchain not installed
Usage
import sys
sys.path.insert(0, '/app/environment/skills/evo-python-build-fixer/scripts')
from utils import (
diagnose_repo,
find_import_errors,
generate_unified_diff,
write_patch_file,
apply_patches,
write_failed_reasons
)
# Step 1: Diagnose
repo_path = '/path/to/repo'
errors = diagnose_repo(repo_path)
# Step 2: Write analysis
write_failed_reasons('/path/to/failed_reasons.txt', errors)
# Step 3: Generate patches
patch_content = generate_unified_diff(original_lines, modified_lines, filepath)
write_patch_file(patch_content, '/path/to/repo/patch_1.diff')
# Step 4: Apply patches
apply_patches(repo_path, ['/path/to/repo/patch_1.diff'])
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

evo-python-build-fixer is a skill published in the GitHub repository OpenLAIR/OpenSkill (90 stars, last pushed 2d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 380 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-11.
