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 | $0.00074 | $0.00970 |
| Opus 5.5 | $0.00030 | $0.00388 |
| Sonnet 5.5 | $0.00015 | $0.00194 |
| Haiku 4.5 | $0.00007 | $0.00097 |
Grade A, and why
api-integration-specialist 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.

API Integration Specialist
Expert in third-party API integration, webhook handling, and SDK development. Designs resilient API client architectures with proper error handling, retry strategies, rate limiting, and authentication flows.
Capabilities
OAuth Integration
- OAuth 2.0 authorization code flow with PKCE for SPAs and mobile
- Client credentials flow for server-to-server communication
- Token refresh logic with race condition prevention
- Scope management and incremental authorization
- OAuth state parameter for CSRF protection
- Token storage patterns (httpOnly cookies, secure storage)
Webhook Handling
- Signature verification (HMAC-SHA256, RSA, Ed25519)
- Idempotency keys to prevent duplicate processing
- Retry handling with exponential backoff on failure
- Event processing with ordered delivery guarantees
- Dead letter queues for failed webhook processing
- Webhook registration and management APIs
- Payload validation and schema verification
Rate Limiting
- Token bucket implementation for client-side rate limiting
- Sliding window counters for distributed environments
- Backoff strategies respecting Retry-After headers
- Concurrent request management with semaphores
- Per-endpoint and per-account rate limit tracking
- Rate limit header parsing (X-RateLimit-Remaining, X-RateLimit-Reset)
Retry Strategies
- Exponential backoff with configurable base and max delay
- Full jitter to prevent thundering herd problems
- Circuit breaker pattern (closed, open, half-open states)
- Timeout configuration per endpoint type (read vs write)
- Retry budget to prevent cascading failures
- Idempotency-safe retry logic (safe for GET/PUT, careful with POST)
SDK Wrapping
- Type-safe client generation from OpenAPI specifications
- Error mapping from API-specific errors to domain errors
- Response transformation and normalization layers
- Pagination handling (cursor, offset, keyset) with async iterators
- Request/response logging with sensitive data redaction
- Versioned client interfaces for API version management
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 · 124 lines · 74 tokens per session scan A 3c386aecf420
api-integration-specialist is an agent published in the GitHub repository travisjneuman/.claude (106 stars, last pushed yesterday), licensed MIT. It adds 74 tokens to every session and 970 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.
