Usage

The tools below are invoked by the agent, not typed by the user. In the chat, just ask naturally — e.g. "index this project" or "what does the auth module do?" — and the agent calls the matching tool automatically. By default (lazyIndexing) files are indexed the moment the model reads them, so memory fills in while you work. watch_repo keeps explicitly-watched roots fresh in the background; index_repo forces a full backfill of a project (unchanged files are skipped).

Tool	Purpose
index_doc file_path	Index one document (PDF/MD/txt): chunk → LLM summary → store with path:line. Unchanged files are skipped.
index_repo root	Index a whole project: docs get LLM summaries, code files get a zero-token symbol table. Incremental, cleans up deleted files, cross-links docs to symbols.
watch_repo root	Enable automatic refresh: a background poll detects new/changed files (mtime + content hash) and re-indexes only those.
query_memory query	BM25 search over docs + symbols + experience, optionally query-expanded by the LLM. Returns ranked hits with sources and doc→symbol references.
remember problem solution	Save an experience note. Similar problems supersede instead of duplicating.
forget id_or_query	Delete stale experience notes.

Configuration

Key	Default	Meaning
memoryDir	.dsh-project-memory	store directory inside each indexed root
chunkChars	3000	max chars per document chunk
maxChunksPerFile	40	max chunks per document
llmQueryExpansion	false	expand queries via ctx.llm before BM25 (off by default to save tokens)
expansionCount	6	max expansion variants
lazyIndexing	true	index files the moment the model reads them (fs/observed)
autoIndexOnFirstUse	false	full scan of the current working directory on plugin load (opt-in)
watch	true	enable the background refresh
watchInterval	15	poll interval (seconds)

Toggling features

The two most relevant switches are lazyIndexing (index a file the moment the model reads it; default on) and autoIndexOnFirstUse (full scan of the current working directory on plugin load; default off).

Settings live in the plugin's config object. To change them, add an override entry to your profile's cordis.patch.yml — for the web profile that is ~/.dsh/profiles/web/cordis.patch.yml:

- id: project-memory
  config:
    lazyIndexing: true          # on: index files as the model reads them (default)
    autoIndexOnFirstUse: false  # off: no upfront full scan (default)
    llmQueryExpansion: false    # off: do not spend tokens on LLM query expansion (default)
    watch: true                 # on: background refresh for watched roots (default)
    watchInterval: 15           # poll interval in seconds

Only list the keys you want to change; the rest fall back to the plugin defaults. Verify the result with dsh --profile web --dump-config.

For a one-off run without editing the profile, pass the override as a CLI patch overlay:

dsh web --patch ./config.yml

where config.yml contains the same override block.
