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.

SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Rogue Agent · line 153 Skill modifies its own code, configuration, or behavior at runtime. Self-modification enables an agent to escalate privileges, disable safety constraints, or install persistent backdoors.Fix: Prevent the skill from modifying its own code, SKILL.md, or configuration files. Treat skill files as read-only at runtime.
What it costs to keep this loaded
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 | $0.00031 | $0.01706 |
| Opus 5 | $0.00015 | $0.00853 |
| Sonnet 5 | $0.00006 | $0.00341 |
| Haiku 4.5 | $0.00003 | $0.00171 |
Grade A, and why
fxview-parquet-consumer 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 6d ago.
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 — 156 lines — stays where its author put it; the contents beside it link to each section on GitHub.
FXView Tick Parquet Consumer
Read FXView tick data from Parquet files produced by the MT5 tick collection system.
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.
When to Use This Skill
Use this skill when:
- Reading or querying FXView tick Parquet files
- Building adapters or pipelines for FXView tick data
- Writing DuckDB queries against tick data
- Integrating tick data into Python or Rust pipelines
- Checking tick data schema or file layout

This skill summarizes the verified schema. For full verification details, flags distributions, and row group internals, see the source document.
Schema
All 6 columns are non-nullable. Schema is identical between EURUSD and XAUUSD files.
| Column | Arrow Type | DuckDB Type | Nullable | Notes |
|---|---|---|---|---|
| time_msc | Int64 | BIGINT | NO | Unix epoch milliseconds |
| bid | Float64 | DOUBLE | NO | Bid price |
| ask | Float64 | DOUBLE | NO | Ask price |
| last | Float64 | DOUBLE | NO | Always 0.0 for FXView forex -- IGNORE |
| volume | Int64 | BIGINT | NO | Always 0 for FXView forex -- IGNORE |
| flags | UInt8 | UTINYINT | NO | MqlTick flags bitmask (3 values: 4, 130, 134) |
Parquet Footer Metadata
Key-value pairs embedded in every file footer:
| Key | Example Value | Purpose |
|---|---|---|
| symbol | EURUSD | Bare symbol name (no FXVIEW_ prefix) |
| digits | 5 (EURUSD) / 2 (XAUUSD) | Price decimal digits |
| broker | FXView | Broker name |
| created_at | 2026-03-24T10:32:35.101090+00:00 | File creation timestamp (RFC3339 UTC) |
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.

fxview-parquet-consumer is a skill published in the GitHub repository terrylica/cc-skills (72 stars, last pushed yesterday), licensed MIT. It adds 31 tokens to every session and 1,706 once invoked, about $0.0002 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.
