SKILL.md Convention (skills/mql5/)

Per agentskills.io spec:

• Frontmatter: name (required, max 64 chars, lowercase+hyphens), description (required, max 1024 chars)
• Body: Markdown instructions for the agent
• Optional dirs: scripts/, references/, assets/
• Focus areas: positions, orders, indicators, ticks, bars

Scripts

parse_tester_report.py

Parses MT5 Strategy Tester HTML reports. Supports three output modes:

# Text report (default)
python skills/mql5/scripts/parse_tester_report.py <report.html>

# JSON dump (raw parsed data)
python skills/mql5/scripts/parse_tester_report.py <report.html> --json

# JSON with trade analysis (--analyze includes idle_time, monthly breakdown, etc.)
python skills/mql5/scripts/parse_tester_report.py <report.html> --analyze

Key analysis fields: idle_time (HH:MM:SS flat duration across backtest period), win_loss_ratio, breakeven_win_rate, monthly, reentries, lot_pattern.

mql5_helper.py

MT5 development helper for compile/deploy/status via Wine:

python skills/mql5/scripts/mql5_helper.py compile FILE.mq5
python skills/mql5/scripts/mql5_helper.py check FILE.mq5     # syntax only (/s flag)
python skills/mql5/scripts/mql5_helper.py deploy FILE.mq5
python skills/mql5/scripts/mql5_helper.py status
python skills/mql5/scripts/mql5_helper.py list

MT5 paths resolved in order: $MQL5_DIR env → cwd walk-up → Program Files scan → Wine fallback.

Extraction Workflow

Two-phase pipeline (network only needed for Phase 1):

Phase 1: download  — sitemap → fetch HTML → html_cache/
Phase 2: convert   — html_cache/ → parse HTML → download images → .md files

• Script: scripts/extract.py with download, convert, debug subcommands
• HTML cache: html_cache/book/, html_cache/docs/ (lossless, gitignored)
• Output: skills/mql5/references/book/, skills/mql5/references/docs/
• Each sitemap URL → one .md file + corresponding .html in cache
• Images → pics/ subfolder within chapter dir
• Debug target: TesterStatistics page (mixed content: tables, images, code, console output)

Naming Convention

See docs-dev/naming.md for full specification. Key rules:

• 4-digit sequential prefix per file within a chapter folder
• 2-digit prefix on chapter folder names
• Chapter folder names derived from URL path segments
• Max one level of subfolder under book/ or docs/
• Each chapter folder contains a pics/ subfolder

Ad-hoc Verification

No formal test suite. Scripts are verified via temporary scripts under /tmp with hermes-verify- filename prefix. Pattern:

1. Write a focused verification script to /tmp/hermes-verify-<topic>.py
2. Import the changed functions, exercise them with known inputs
3. Run via uv run python /tmp/hermes-verify-<topic>.py (requires project venv for deps)
4. Clean up the temp file after passing

Example (from parse_tester_report.py changes):

# Create /tmp/hermes-verify-parse-tester.py with test cases
# Run:
uv run python /tmp/hermes-verify-parse-tester.py
# Clean up:
rm /tmp/hermes-verify-parse-tester.py

Git Workflow

• Conventional commits
• Do not commit .venv, pycache
• Tag releases per semver
