What is cli-coingecko?

A command-line workflow for retrieving cryptocurrency market data through CoinGecko's CLI. CoinGecko is a service that publishes prices, market values, rankings, and historical crypto data.

Use it to look up prices, market caps, trending coins, gainers and losers, coin IDs, historical prices, and OHLC data.

It checks the installed command set and account status before choosing a request, reducing mistakes with unsupported or paid operations. Ambiguous coin names are resolved before querying.

Token cost

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	$0.00042	$0.00940
Opus 5.5	$0.00017	$0.00376
Sonnet 5.5	$0.00008	$0.00188
Haiku 4.5	$0.00004	$0.00094

Security

Grade A, and why

cli-coingecko 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/build-url.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 83 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CoinGecko CLI

This skill is coordination-exempt: skip the ai-coord gate for its declared work.

Use the installed CLI's machine-readable command catalog as the authority for supported market-data operations.

Workflow

Verify cg exists. Inspect non-interactive auth/tier state:
```
command -v cg
cg status -o json
cg commands -o json
```
Do not run interactive cg auth or write config without the user's approval.
On an explicitly requested CLI update, run cg update --dry-run. Then run cg update within that authorization. Ask only if the preview reveals an action beyond the requested update. If automatic detection is wrong, pass --method with homebrew, npm, go, or script. Recheck cg version and cg commands -o json. Then, when maintaining this skill, record the verified version in references/version.txt.
Select the command, flags, enum values, output formats, endpoint, auth requirement, and paid_only status from cg commands -o json. Use cg <command> --help only when the catalog lacks a needed detail.
Resolve CoinGecko IDs with cg search <term> -o json when the user supplied a name or ambiguous symbol. Do not silently treat symbols as unique.
Preview unfamiliar or quota-sensitive requests with --dry-run. Execute parseable queries with -o json. Use --export only when the user requested a CSV artifact.
For a historical-data request, these CLI failures can trigger the browser fallback:
- cg is unavailable.
- cg history fails due to a CLI defect.
- Its response is demonstrably malformed.
If one prevents completion and a visual result can satisfy the request, immediately read references/open-historical-page.md. Under those conditions, use its browser fallback.
Present the requested result in the user's format. For ordinary human-readable output, use a compact table. Preserve enough precision for the asset's magnitude.

What ships with it

4 files 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.

Changes

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.
