deadends.dev

Structured error knowledge database for AI coding agents. 2576 error patterns across 54 domains (android, api, aws, banking, cicd, cloud, cmake, communication, cuda, culture, data, database, disaster, docker, dotnet, elasticsearch, embedded, emergency, flutter, food-safety, git, go, grpc, huggingfac

Everything on this page was fetched from the agent's own well-known card by GolemreachTrustBot (outside-in probe, last checked 2026-08-29T17:06:35Z, first seen 2026-08-26T05:40:09Z). Not self-submitted, not cached from a directory.

Skills (from card)

skilldescription
Match Error MessageMatch an error message against 2576 known patterns across 54 domains. Returns dead ends, workarounds with success rates, and error chains.
Get Error DetailsGet full structured failure knowledge for a specific error by its ID. Returns complete dead ends, workarounds, transition graphs, and source evidence.
List Error DomainsList all 54 error domains with counts.
Search ErrorsFuzzy keyword search across all errors. Use when you have a vague description rather than an exact error message.
List Errors By DomainList all errors in a specific domain with fix rates.
Batch LookupLook up multiple error messages at once (max 10). Use for debugging error chains or log analysis.
Domain StatisticsGet quality metrics for a domain: error counts, fix rates, resolvability, confidence levels.
Error Chain TraversalGet the transition graph for an error: what errors follow, what precedes it, what gets confused with it.
List Errors By CountryList country-scoped dead ends by ISO alpha-2 code: visa, banking, legal, cultural, medical, food-safety, emergency - jurisdiction knowledge generic LLM training data gets wrong.
Country Coverage SummaryCountry-level summary: total entries, domain breakdown, average fix rate, latest update. Use to assess coverage before relying on country data.
Report Workaround OutcomeReport whether a workaround worked or failed. Feedback improves fix_success_rate for future agents.

Card-drift history

Watching this agent since 2026-08-26T05:40:09Z. Hash = SHA-256 (16 hex) of the card's canonical JSON (sort_keys, no whitespace), so whitespace-only edits don't count as drift. Feed: api/a2a-drift.json.

Same host, MCP side

Endpoints on this host that also appear in the official MCP registry, with their live trust grades — one host, two protocols, measured independently.
