Unset by default. Its resolved state is reported by the similarity section of the specmgr://config resource."

"name": "SPECMGR_FEAT_WARMUP_DISABLED",
"description": "Presence-based opt-out for the feat domain's two background cache-warming phases (frontmatter and full-parse) of the unified server-startup warmup thread: set to any value to skip both phases; when set together with SPECMGR_SIMILARITY_DISABLED, no warmup thread is started at all.

"description": "Path to an executable speaking the PlantUML CLI contract, one of exactly three PlantUML validation-source selectors (the first one set, in JAR then BIN then URL order, is the only source used; no fall-through, no PATH discovery, no public default; all three unset is the offline structure-only floor).

"default": "40",
"description": "Maximum length (in characters) of a resolved node's title label in the reference-graph diagrams (the get_reference_diagram / get_reference_diagram_all MCP tools and the specmgr diagram refs CLI): labels longer than the limit are cut at the last word boundary within the limit (a hard cut when there is none) with an ellipsis appended; the diagram title itself and unresolved node ids are never truncated. An integer; the default 40 applies when the variable is unset or set to an invalid value (empty, non-integer, or less than 1)."
},
{
"name": "SPECMGR_TESTS_NO_DOTENV",
"description": "Presence-based test/CI sentinel: set to any value to skip the CLI's module-level default .env load entirely, so the process runs under the CI (source-less) condition whatever the local (gitignored) .env configures; this is what keeps the specmgr coverage-badge pre-commit hook's source-less re-run source-less end-to-end. Unset by default, never set outside test runs."
},
{
"name": "FASTEMBED_CACHE_PATH",
"format": "filepath",
"default": "<tempdir>/fastembed_cache",
"description": "Cache directory for the semantic-similarity feature's embedding model (the third-party fastembed backend's own variable, not a SPECMGR_* one): set to a directory to cache the model there; an unset or empty value falls back to the default <tempdir>/fastembed_cache, where <tempdir> is the process's temporary directory (e.g. /tmp on Linux). Unset by default. The resolved directory is reported by the similarity section of the specmgr://config resource."
