# frontier-digest — FH Frontier Insight Collection & Synthesis > Automatically collects the latest AI/agent/harness engineering trends from HackerNews and arxiv, > then compresses and synthesizes them into insights directly relevant to forge-harness skills and structure. ## Triggers ``` /frontier-digest # immediate execution /frontier-digest --save # save result to file "what's on the frontier" "this week's AI trends" "harness trends" "latest agent developments" "any ideas for improving the harness?" ``` --- ## Step 0. API Environment Detection This is the trend-scan specialization (rung 3) of the **Deep-Research Capability Ladder** (`../../../../knowledge/shared/harness-core/deep_research_capability_ladder.md`). The ladder owns the **cross-rung routing** (when a task is trend-scan at all vs general research); the `Priority:` block below is frontier-digest's own **internal engine resolution** for the HN/arxiv case (API-key vs WebSearch) — a narrower detection, not a re-definition of the cross-rung ladder. ``` Priority: 0. /deep-research built-in available (check live session skill list) → use it as the collection+verification engine (staged source gathering, cross-checking, cited synthesis) — Tier-0 route, no API key needed 1. ANTHROPIC_API_KEY environment variable → Claude Sonnet 2. Neither → WebSearch mode (raw data only, no synthesis) ``` Report detection result in one line.
