Overview

Search, grep, browse, and read across registered MFS data sources via the `mfs` CLI — codebases, docs, PDFs, web crawls, databases (postgres/mysql/mongo/snowflake/bigquery), issue trackers (jira/linear/github), CRMs (hubspot), chat (slack/discord/gmail/feishu), object stores (s3/gdrive). Use whenever the user asks to find, locate, look up, look across, or read something out of an already-configured MFS index. Trigger phrases include "search the codebase for", "find anywhere about", "where is X mentioned", "look across our [slack/jira/postgres/etc]", "any past tickets/RFCs/commits about", "what does our wiki say about", "cat / head / tail / ls / tree this MFS path". Do NOT use for: registering a NEW data source (use `mfs-ingest`), changing connector config, kicking off re-ingest, or any write/delete operation — `mfs` is read-only.

MFS — find / read across configured sources

1. What MFS is

A retrieval layer that exposes many kinds of content as a unified path tree and makes that tree searchable through one hybrid index:

One CLI (mfs), one mental model. Local dir, Postgres, GitHub repo, Slack workspace, S3 bucket, BigQuery dataset — all addressed as paths under their <scheme>:// URI. Same verbs everywhere: ls / tree / cat / head / tail / grep / search / export.
One hybrid index. Dense vectors (semantic) + BM25 (keyword) fused per query — covers conceptual recall and exact-token recall in one call.
POSIX-style locators. Every search hit carries a locator that reopens the exact unit: {"lines":[s,e]} for text/code, a PK dict for rows/issues/threads.

2. When to use MFS — and when NOT to

Situation	Use MFS?
1000+ files / rows / pages, you don't know where the answer is	✅
Cross-source question ("any past tickets / commits / RFCs about X")	✅ `--all`
Concept-style query that won't match literally	✅ `--mode semantic`
You already know the exact file + roughly where to look	❌ plain `cat`/`grep`
Exact identifier / error code in 5 files you can list	❌ plain `grep`/`rg`
Real-time tailing of a live log	❌ index lags ingest
The source isn't in MFS yet	wrong skill, use `mfs-ingest` to register first

Rule: use the smallest tool that answers the question. MFS pays off when the scope is too big for rg.

Borderline — ASK the user:

Ask	Likely answer	Why
"Summarise these 10 PDFs"	✅ `mfs search` + `cat --peek` per hit	each PDF gets a `converted_md` artifact + searchable chunks
"Find similar tickets to this one"	✅ paste the ticket text as the search query	semantic over `row_text` does similarity matching
"Watch for new slack messages"	❌ no `watch` capability; use Slack's API	index lags ingest
"Look up user 12345"	❌ `mfs cat <source> --locator '{"id":12345}'` directly (skip search)	one-record-by-id doesn't need ranking

3. Pre-flight — confirm the source is indexed

Before running any query, especially on cross-source asks:

mfs status                  # server up? any connectors registered?
mfs connector inspect <uri> # this connector's object/job summary
mfs ls <uri> --json         # per-entry capabilities + indexable / search_status

Server unreachable → tell user to start it (mfs serve start if self-hosted), or this skill can't proceed.
connectors empty → user hasn't ingested anything yet. Redirect to mfs-ingest — don't try to search nothing.
search_status: unavailable for the target URI → only grep / ls / cat work; offer those or redirect to mfs-ingest for a re-sync.
building → sync in flight; fall back to mfs grep (works without an index) until done.
partial → recall incomplete but usable; flag the caveat to the user.

4. The core workflow: search → locate → browse

        search                 locate                browse
  ┌──────────────────┐   ┌──────────────────┐   ┌─────────────────────┐
  │  semantic + BM25 │ → │ result has lines │ → │  cat --range / cat  │
  │  finds candidates│   │  or a locator    │   │  --peek to confirm  │
  └──────────────────┘   └──────────────────┘   └─────────────────────┘

On large corpora this loop is the whole point: read only the part that matters. On small corpora it's still fine, just lighter.

Concrete:

Search:

mfs search "<what the user actually wants>" <path-or-uri> --top-k 10

Locate — every hit's envelope carries locator:
- text/code → {"lines":[start,end]} → mfs cat <source> --range start:end
- structured (row/issue/thread) → PK dict → mfs cat <source> --locator '{...}'
- once-per-object (dir/schema summary, image VLM) → null → mfs cat <source>

Browse — verify only what's needed:

mfs cat --peek <file>       # outline (headings / function signatures)
mfs cat --skim <file>       # peek + one-line summaries per section
mfs head -n 20 <uri>        # first records of a structured object
mfs tree <uri> -L 2         # subtree shape

5. Index requirement rules of thumb

mfs search requires an index.
mfs grep works without — pushdown → BM25 → linear scan fallback.
mfs ls / tree / cat / head / tail browse without an index.

6. Search modes

mfs search defaults to hybrid. Override only when you know why.

`--mode`	Mechanic	When
`hybrid` (default)	dense + BM25 fused with RRF	almost always
`semantic`	dense only	conceptual query, wording won't match literally
`keyword`	BM25 only	exact-term (config key, error code) without semantic drift

Other useful flags:

--top-k N — default 10; raise to 20-30 on a weak first round.
--all — search every registered connector. Otherwise scope to a path/URI prefix.
--kind <list> — restrict chunk kinds (row_text, thread_aggregate, body, summary, vlm_description, …).
--collapse — keep only the top-scoring chunk per object; later chunks from the same source are dropped, not merged. Recall stays as-is (the query still hits the same candidates), but the visible result count can fall below --top-k — collapse is a post-filter, not a re-rank. If you want N distinct objects, raise --top-k (e.g. --top-k 30 --collapse).

`--all`: when yes, when no

✅ Cross-source recall — "any past tickets / commits / RFCs / slack about X".
❌ You know the source — scope to slack://; postgres + jira + docs together aren't comparable.
⚠ More than ~5 registered connectors — ASK the user whether to fan out widely or scope to the 2-3 likeliest sources first.

7. Decision tree — pick the smallest useful tool

Signal in the ask	Sub-task	Use
natural-language question / sentence	exploratory	`mfs search "<q>" <scope>`
paraphrased / conceptual wording	semantic-only	`mfs search --mode semantic`
exact identifier / config key / unique phrase	literal anchor	`mfs grep "<lit>" <path>` (or `rg`)
filename / directory pattern	path lookup	`find` / shell glob / `fd`
known file + needs outline	structural overview	`mfs cat --peek <file>`
known file + compact summary	dense overview	`mfs cat --skim <file>`
search hit + surrounding context	reopen	`mfs cat <file> --range s:e`
structured hit (row/issue/thread)	reopen by PK	`mfs cat <source> --locator '{...}'`
several close candidates	compare	`mfs cat --peek` each, then pick
single record + known key	no-search lookup	`mfs cat <source> --locator '{"id":12}'`
first / last N	sample	`mfs head -n N` / `mfs tail -n N`
subtree shape	orient	`mfs tree -L 2 <uri>`
full object for offline tooling	export	`mfs export <uri> <file>`

mfs search requires an explicit scope or --all.

8. Command cheat sheet

Search

mfs search "<query>" <path-or-uri>             # default: hybrid, top-k=10
mfs search "<query>" --all                     # whole namespace
mfs search "<query>" <path> --top-k 20         # more candidates
mfs search "<query>" <path> --mode semantic    # dense-only
mfs search "<query>" <path> --mode keyword     # BM25-only
mfs search "<query>" <path> --kind row_text    # restrict chunk kinds
mfs search "<query>" <path> --collapse         # keep top hit per object (post-filter, may return < top-k)

Grep

mfs grep "<pattern>" <path>          # pushdown -> BM25 -> linear

mfs grep is not grep. The three-tier dispatch is:

Pushdown — for structured connectors (postgres, mongo, jira, …) the pattern is shipped to the source as a LIKE / regex filter. Literal-exact, token-level; no regex on most structured connectors.
BM25 over indexed objects — for body/code/document chunks already in Milvus, the pattern is fed through the same sparse index search --mode keyword uses. That is a tokenized, ranked lookup, not a literal substring scan: an analyzer split like getUserId → get, user, id will rank userId as a hit; a CJK pattern with no analyzer match returns nothing even when the literal bytes are present. If you need "does this exact byte string appear anywhere?", mfs export the object and run rg locally — mfs grep has no "force linear over indexed objects" flag.
Linear scan — only for not-indexed files in scope (file connector before mfs add). True substring / regex.

For exact-exhaustive on a huge structured object, mfs export then local grep / rg.

Read

mfs cat <path>                                  # full content (refused if "lazy")
mfs cat <path> --range A:B                      # lines A..B-1 (1-based, end-exclusive)
mfs cat <path> --locator '{"id":12}'            # reopen a structured record
mfs cat <path> --peek                           # outline only
mfs cat <path> --skim                           # peek + per-section summaries
mfs cat <path> --meta                           # stat-style, not content

Density ladder:

Mode	Use it when
`--peek`	"show me the outline"
`--skim`	+ one-line summary per section, still concise
(default)	full content; small file or really need it
`--range A:B`	already know which lines matter (e.g. search hit)

mfs head -n 50 <path>           # first 50 lines/records
mfs tail -n 50 <path>           # last 50; native-accel reverse read

For a lazy rows.jsonl / messages.jsonl, head is how to see record shape without paying full-scan cost.

Browse

mfs ls <uri>                    # one level
mfs tree <uri> -L 2             # depth-bounded recursive

NOT a substitute for search when the target is unknown and conceptual.

Export

mfs export <uri> <out-file>     # full object to disk for jq/awk pipelines

cat of a huge lazy object is refused — use export for bulk processing.

Status (useful before AND during search work)

mfs status                      # server + all connectors
mfs connector inspect <uri>     # one connector's object/job summary
mfs connector list              # list registered connectors
mfs job list                    # recent indexing jobs (background re-syncs)

Always prefer --json when output will be parsed.

9. Weak results → recover, don't thrash

If top hits look off-topic:

Rewrite with synonyms / domain terms. ASK the user for the domain term they'd actually use if vague. One clarifier beats five blind queries.
Raise --top-k to compare distinct candidates.
mfs cat --peek the top few to compare structure.
Switch mode — semantic if hybrid was keyword-noisy; keyword if specific terms should be the anchor.
Then literal grep — only if the task has a real literal anchor (error

## 8. Command cheat sheet

### Search

```bash
mfs search "<query>" <path-or-uri>             # default: hybrid, top-k=10
mfs search "<query>" --all                     # whole namespace

```

### Grep

```bash
mfs grep "<pattern>" <path>          # pushdown -> BM25 -> linear
```

**`mfs grep` is not `grep`.** The three-tier dispatch is:

1. **Pushdown** — for structured connectors (`postgres`, `mongo`,
   `jira`, …) the pattern is shipped to the source as a LIKE / regex
   filter. Literal-exact, token-level; no regex on most structured
   connectors.
2. **BM25** over indexed objects — for `body`/`code`/`document` chunks
   already in Milvus, the pattern is fed through the same sparse
   index `search --mode keyword` uses. That is a tokenized,
   ranked lookup, **not** a literal substring scan: an analyzer split
   like `getUserId` → `get`, `user`, `id` will rank
   `userId` as a hit; a CJK pattern with no analyzer match returns
   nothing even when the literal bytes are present. If you need
   "does this exact byte string appear anywhere?", `mfs export` the
   object and run `rg` locally — `mfs grep` has no "force linear over
   indexed objects" flag.
3. **Linear scan** — only for not-indexed files in scope (file
   connector before `mfs add`). True substring / regex.

For exact-exhaustive on a huge structured object, `mfs export` then
local `grep` / `rg`.

### Read

```bash
mfs cat <path>                                  # full content (refused if "lazy")
mfs cat <path> --range A:B                      # lines A..B-1 (1-based, end-exclusive)
mfs cat <path> --locator '{"id":12}'            # reopen a structured record

mfs cat <path> --meta                           # stat-style, not content
```

Density ladder:

| Mode | Use it when |
|---|---|
| `--peek` | "show me the outline" |
| `--skim` | + one-line summary per section, still concise |
| (default) | full content; small file or really need it |
| `--range A:B` | already know which lines matter (e.g. search hit) |

```bash
mfs head -n 50 <path>           # first 50 lines/records
mfs tail -n 50 <path>           # last 50; native-accel reverse read
```

For a lazy `rows.jsonl` / `messages.jsonl`, `head` is how to see record
shape without paying full-scan cost.

### Browse

```bash
mfs ls <uri>                    # one level
mfs tree <uri> -L 2             # depth-bounded recursive
```

NOT a substitute for `search` when the target is unknown and conceptual.

### Export

```bash
mfs export <uri> <out-file>     # full object to disk for jq/awk pipelines
```

`cat` of a huge lazy object is refused — use `export` for bulk processing.

### Status (useful before AND during search work)

```bash
mfs status                      # server + all connectors
mfs connector inspect <uri>     # one connector's object/job summary
mfs connector list              # list registered connectors
mfs job list                    # recent indexing jobs (background re-syncs)
```

Always prefer `--json` when output will be parsed.

Listed tools are metadata hints, not tested compatibility. Agent prompts are suggested handoffs.

Start with one small task

1Read the source. Confirm the input, expected output, dependencies and permissions.
2Ask your agent for a plan. Approve setup and any costs before running a small isolated test.
3Check the output and changed files. Report only what actually ran; keep the source revision for reproduction.

Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.

Overview

MFS — find / read across configured sources

1. What MFS is

2. When to use MFS — and when NOT to

3. Pre-flight — confirm the source is indexed

4. The core workflow: search → locate → browse

5. Index requirement rules of thumb

6. Search modes

--all: when yes, when no

7. Decision tree — pick the smallest useful tool

8. Command cheat sheet

Search

Grep

Read

Browse

Export

Status (useful before AND during search work)

9. Weak results → recover, don't thrash
