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 | $0.00061 | $0.00557 |
| Opus 5 | $0.00030 | $0.00279 |
| Sonnet 5 | $0.00012 | $0.00111 |
| Haiku 4.5 | $0.00006 | $0.00056 |
Grade A, and why
Bankr Agent - Error Handling 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 10d 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.
What it actually says
Bankr Error Handling
Resolve Bankr API errors and authentication issues.
Authentication Errors (401)
Symptoms
- HTTP 401 status code
- "Invalid API key" or "Unauthorized" message
Resolution
Present these setup instructions to the user:
Step 1: Create an API Key
Visit https://bankr.bot/api to create a new API key
Step 2: Set Environment Variable
# Add to shell profile (~/.zshrc or ~/.bashrc)
export BANKR_API_KEY=bk_your_api_key_here
Step 3: Restart Claude Code
Close and reopen the terminal/Claude Code session
Important: Do NOT retry when authentication fails. User must fix API key first.
Common Job Failures
| Error | Cause | Resolution |
|---|---|---|
| Insufficient balance | Not enough tokens | Check balance, reduce amount |
| Token not found | Invalid symbol/address | Verify token exists on chain |
| Slippage exceeded | Price moved too much | Retry or try smaller amount |
| Transaction reverted | On-chain failure | Check transaction details |
| Rate limit exceeded | Too many requests | Wait and retry |
HTTP Status Codes
| Code | Meaning | Action |
|---|---|---|
| 400 | Bad request | Check prompt format |
| 401 | Unauthorized | Fix API key (see above) |
| 402 | Payment required | Ensure wallet has BNKR on Base |
| 429 | Rate limited | Wait and retry |
| 500 | Server error | Retry after delay |
Troubleshooting Checklist
- API Key: Set, starts with
bk_, Claude Code restarted after setting - Network: Internet working, api.bankr.bot reachable
- For Trading: Wallet has sufficient balance, token exists on chain
Reporting Errors to Users
- State what went wrong simply
- Provide specific fix steps
- Avoid technical jargon
- Suggest alternatives
Example:
Your Bankr API key is not configured. To set it up:
1. Visit https://bankr.bot/api to create an API key
2. Set BANKR_API_KEY in your environment
3. Restart Claude Code
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.

Bankr Agent - Error Handling is a skill published in the GitHub repository BankrBot/claude-plugins (85 stars, last pushed 5mo ago), licensed MIT. It adds 61 tokens to every session and 557 once invoked, about $0.0003 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 2026-08-30.
