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.

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 | $0.00064 | $0.00912 |
| Opus 5.5 | $0.00026 | $0.00365 |
| Sonnet 5.5 | $0.00013 | $0.00182 |
| Haiku 4.5 | $0.00006 | $0.00091 |
Grade A, and why
pinescript 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 1mo 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 — 71 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Pine Script Development
Critical Syntax Rules
- Ternary operators MUST stay on one line — splitting across lines causes "end of line without line continuation" error. For complex ternaries, use intermediate variables:
isBull = close > open barColor = isBull ? color.green : color.red - Continuation lines MUST be indented MORE than the starting line — same indentation = error
- NEVER use plot() inside local scopes (if/for/functions) — use conditional value instead:
plot(condition ? value : na) - barstate.isconfirmed — use to prevent repainting on real-time bars
Platform Limits
500 bars history for request.security() | 500 plot calls | 64 drawing objects | 40 request.security() calls | 100KB compiled size
Performance
- Tuple security calls — one
request.security()returning[close, high, low]instead of 3 separate calls - Pre-allocate arrays with
array.new<type>(size)instead of push-and-resize - Short-circuit signals: build conditions incrementally, exit early when first condition fails
- Cache repeated calculations in variables — Pine recalculates every bar
Debugging
TradingView has no console or debugger. Use these patterns:
- Label debugging:
label.new(bar_index, high, str.tostring(myVar))to inspect values - Table monitor:
table.new()withbarstate.islastfor real-time variable dashboard - Debug mode toggle: wrap all debug code in
if input.bool("Debug", false)— remove before publishing - Repainting detector: track
previousValue = value[1], flag when historical values change
Strategy & Backtesting
- Use
strategy.*functions:strategy.wintrades,strategy.losstrades,strategy.grossprofit - Drawdown tracking:
maxEquity = math.max(strategy.equity, nz(maxEquity[1])), thendd = (maxEquity - strategy.equity) / maxEquity * 100 - Sharpe:
dailyReturn * 252 / (stdDev * math.sqrt(252)) - Walk-forward validation — optimize on period 1, test on period 2, re-optimize on period 2, test on period 3. If metrics degrade > 30%, parameters are overfit.
- Indicator accuracy testing — use forward-looking
close[lookforward]to measure prediction accuracy, track true/false positive rates
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.
- 1mo ago First seen · 71 lines · 64 tokens per session scan A ac71ebe96884
pinescript is a skill published in the GitHub repository iliaal/whetstone (35 stars, last pushed yesterday), licensed MIT. It adds 64 tokens to every session and 912 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-08-30.

Does this product make money at a price someone will pay? Forces contribution margin, a price with a stated basis, and a bottom-up market size — each number labelled measured / assumed / unknown, so a guess can never be read as a calculation.
triage
Triages a PR comment — from a bot (Copilot, CI) or a human reviewer. Routes to the triagehelper.py helper for identity checks, thread snapshotting, isolated-worktree fixes, and publish/reply/resolve mechanics; you classify the finding and apply a justified fix. --dry-run is fully read-only (investigation and a printed…
