# Academic Search — Router This skill is split into two layers: - A **static layer** under `static/` that holds versioned, reusable content fragments (the MCP tool inventory and shared modules, and source routing plus operational rules). - A **dynamic layer** (this file plus `manifest.yaml`) that detects which workflow the user needs and loads that workflow, reaching for shared modules and scripts only when a step needs them. Do not try to apply the search logic from memory or from this router. Always load fragments from disk as described below. ## Routing protocol Follow these five steps every time the skill is invoked. ### 1. Load the manifest and the core layer Read [manifest.yaml](manifest.yaml). It declares the `workflow` axis, the allowed values, and the file paths each value maps to. Also read every file listed under `always_load`: - `static/core/tools.md` — the MCP tool inventory (core search, extended search, PubMed utilities) and the shared-module map. - `static/core/routing-and-ops.md` — the T1→T2→T3 source routing quick guide, environment setup, error handling, and limitations. ### 2. Detect the workflow Map the user's need to one or more `workflow` values: - `multi-source-search` — find literature across sources. - `citation-verification` — verify citations extracted from a document. - `mesh-strategy` — build a MeSH/PubMed search strategy. - `citation-file-mgmt` — convert/manage `.nbib`/`.ris`/`.bib` files. - `reference-mgmt` — BibTeX, related-article discovery, ID conversion. A combined request (for example search then export) may need more than one. State the detected workflow(s) in one short line before proceeding. ### 3. Load the matching workflow fragment(s) Read the file mapped for each detected workflow (under `references/workflows/`). Do **not** read every workflow. Each workflow file links to the shared modules it needs. ### 4. Run the workflow using the loaded material Apply the loaded material in this order: 1. Core tools and routing (`core/tools.md`, `core/routing-and-ops.md`) — which MCP tool for which need, and the T1→T2→T3 fallback chain that is the standard execution order across all workflows. 2. The workflow fragment — its specific steps. 3. Shared modules and scripts on demand (dedup, citation parser, search strategy, RIS/BibTeX format, format converter). Report specific tool failures and continue with remaining tools; broaden terms when there are no results; fall back to manual generation from MCP-fetched metadata if a script fails twice. ### 5. Reach for references only when needed The files under `references/` (and `scripts/`) are deep references, not defaults. Open them on demand per the `references.on_demand` table in the manifest — for example `references/source-tiers.md` for the full reliability classification, `references/dedup-engine.md` / `references/citation-parser.md` / `references/search-strategy.md` / `references/ris-bibtex-format.md` for the shared modules, and `scripts/academic_
