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 | $0.00029 | $0.01601 |
| Opus 5 | $0.00015 | $0.00800 |
| Sonnet 5 | $0.00006 | $0.00320 |
| Haiku 4.5 | $0.00003 | $0.00160 |
Grade A, and why
log-reader 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.
How it starts
The opening of the file, as written. The whole thing — 219 lines — stays where its author put it; the contents beside it link to each section on GitHub.
MT5 Log Reader
Read MetaTrader 5 log files directly to access Print() output from indicators, scripts, and expert advisors without requiring manual Experts pane inspection.
Self-Evolving Skill: This skill improves through use. If instructions are wrong, parameters drifted, or a workaround was needed — fix this file immediately, don't defer. Only update for real, reproducible issues.
Purpose
Implement "Option 3" dual logging pattern:
- Print() - MT5 log files (human-readable via Experts pane)
- CSV files - Structured data (programmatic analysis)
Claude Code can autonomously read both outputs without user intervention.
When to Use This Skill
Use this skill when:
- Validating MT5 indicator/script execution
- Checking compilation or runtime errors
- Analyzing Print() debug output
- Verifying unit test results (Test_PatternDetector, Test_ArrowManager)
- User mentions checking "Experts pane" manually
Log File Location
MT5 logs are stored at:
$MQL5_ROOT/Program Files/MetaTrader 5/MQL5/Logs/YYYYMMDD.log
File Format:
- Encoding: UTF-16LE (Little Endian)
- Structure: Tab-separated fields (timestamp, source, message)
- Size: Grows throughout day (typically 10-100KB)
Instructions
1. Construct today's log path
/usr/bin/env bash << 'SKILL_SCRIPT_EOF'
# Determine current date
TODAY=$(date +"%Y%m%d")
# Build absolute path
LOG_FILE="$MQL5_ROOT/Program Files/MetaTrader 5/MQL5/Logs/${TODAY}.log"
SKILL_SCRIPT_EOF
2. Read the entire log file
Use Read tool:
- File path: Absolute path from step 1
- The file contains all Print() statements from MT5 indicators/scripts
- UTF-16LE encoding is automatically handled by Read tool
3. Search for specific content (optional)
Use Grep to filter entries:
Pattern: indicator name, "error", "test.*passed", etc.
Path: Log file path from step 1
Output mode: "content" with -n (line numbers)
Context: -A 5 for 5 lines after matches
4. Analyze recent entries (optional)
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.

log-reader is a skill published in the GitHub repository terrylica/cc-skills (62 stars, last pushed today), licensed MIT. It adds 29 tokens to every session and 1,601 once invoked, about $0.0001 per session on Opus 5. 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 2026-09-05.
