> **Run repeatable, evidence-grounded LLM batch jobs over free and local models. Every claim is typed, and every quote is checked against the source at exact character offsets. Scores and interpretations still need human review.**

Harness Fleet turns a pile of text into answers you can check. You describe the job — *score these accounts*, *pull the pricing out of these pages*, *flag the ones that matter* — and it returns a typed result for every record with the exact sentence it relied on. It runs on free or local AI models by default, keeps all state in a local file, and ships the assistant playbooks for every fleet product, so one install gives your AI client the account, partner, and career skills too.

*Canonical CLI is `harness-fleet`. The account-fleet and career-fleet distributions ship their own entry points from their own checkouts — install one fleet per environment.*

**New here?** [One-click install](#one-click-install) → [60-second demo](#quickstart--60-second-demo-no-api-keys) → [which fleet do I want?](#which-fleet-do-i-want)

## Start here (no coding needed)

1. **Install.** macOS/Linux: `./install.sh` · Windows: `powershell -ExecutionPolicy Bypass -File install.ps1`
   It makes its own private Python environment, sets up a workspace, and connects Claude Desktop or Cursor for you.

   Prefer a terminal one-liner to the installer? This puts the CLI on your PATH without cloning anything:
   ```bash
   uv tool install "git+https://github.com/NatesVibeCode/harness-fleet"
   # or, without uv:  python3 -m pip install "git+https://github.com/NatesVibeCode/harness-fleet"
   ```
2. **Watch it work.** The installer finishes by scoring a set of example records with a built-in fake model — no accounts, no API keys, no cost — and tells you where the results landed.
3. **Get free model access** — about two minutes, no credit card needed: **[FREE-ACCESS.md](FREE-ACCESS.md)**. Until one of those is connected there is nothing for a real run to use.
4. **Ask your assistant.** Restart Claude Desktop (or Cursor) and describe the job in plain words, e.g. *"score these 200 accounts and show me the strongest 25 with quotes."* The bundled skill picks the right commands.

Rather click than type? `harness-fleet studio` opens a local page for choosing which AI tools and models your runs are allowed to use.

## Which fleet do I want?

Every distribution shares one engine — typed claims, SQLite checkpoints, and character-exact quote verification — and ships the assistant skills below. Install one per environment.

| If you want to… | Install | CLI | Skill that drives it |
| --- | --- | --- | --- |
| Score, classify, extract, or triage **your own** text at volume | **harness-fleet** ← you are here | `harness-fleet` | `harness-fleet` |
| Turn an ICP into **scored target accounts** | [account-fleet](https://github.com/NatesVibeCode/account-fleet) | `account-fleet` | `account-fleet` |
| Find and rank **employers and job postings** | [career-fleet](https://github.com/NatesVibeCode/career-fleet) | `career-fleet` | `career-fleet` |
| Find **implementation partners and SIs** | harness-fleet, preset `partner-research` | `harness-fleet` | `partner-fleet` |

Skills are installed into your workspace by `harness-fleet setup` — see [Assistant skills](#assistant-skills-what-installs-where).

## Migrating from free-fleet

Version 0.3.0 renames the `free-fleet` distribution to `harness-fleet` (the old `bulk-lanes` name is gone). Back up your database first, then:

```bash
free-fleet db backup free-fleet.db.bak  # back up with the OLD CLI first (SQLite backup API, WAL-safe)
mv free-fleet.db harness-fleet.db
harness-fleet setup --workspace-root .   # re-installs the skill
harness-fleet mcp install                # re-installs client configs
```

Old packets (`free_fleet_v2` / `bulk_lanes_v2`) no longer read; re-export them from SQLite before upgrading. The `FREE_FLEET_DB` / `BULK_LANES_DB` / `ACCOUNT_FLEET_DB` variables are replaced by the single `HARNESS_FLEET_DB`. There is no downgrade path — restore your backup to go back.

Python 3.10+ is required. This is a command-line tool with an optional AI-assistant integration. It scores source text you supply; the CLI does not browse for companies or fetch job postings automatically. The bundled account-fleet skill guides a connected assistant through that research.

Install and try the offline demo below before running a real list. Real research requires a configured model provider and your own qualification criteria.

---

## 30-Second Example: Raw Accounts In → Scored, Grounded CSV Out

Suppose you have a list of target companies in `accounts.csv`:

```csv
company,careers_text
stripe.com,"We are hiring a Staff Engineer to lead migration off legacy v1 billing pipeline to Kafka..."
hyper_ai,"Looking for Senior Backend Engineer hitting latency limits at 50k QPS on Postgres cluster..."
pinecone.io,"Hiring Infrastructure Engineer scaling vector search across multi-tenant clusters..."
```

### 1. Initialize the account research preset and run

```bash
# Initialize the typed account-research preset (evidence checklist, identified_gap; score/fit_tier derived)
harness-fleet init research-demo --preset account-research

# Process the accounts through free model routes (zero API spend)
harness-fleet run research-demo --input accounts.csv --id-column company --text-column careers_text --run-id campaign-01
```

### 2. Export the top 25 ranked accounts

```bash
harness-fleet export campaign-01 --format csv --sort-by score --desc --top 25 --rank --output ranked_accounts.csv
```

### 3. Output (`ranked_accounts.csv`)

```csv
rank,item_id,score,identified_gap,fit_tier,primary_quote_text
1,stripe.com,92,"Legacy billing migration",tier_1,"lead migration off legacy v1 billing pipeline to Kafka"
```

Illustrative values only; real exports also include source URLs, digests, and quote details. Set your ICP and scoring rubric in the task's `TaskSpec` — a preset plus a task JSON file, edited by hand or by your AI client using the bundled skill. An exact source quote proves the text exists, not that a company will buy your product.

---

## Why You Can Trust the Output

Every output row is gated through deterministic checks *before* it is committed to SQLite. If any check fails, the batch rotates to the next route — nothing unverified is exported.

1. **Deterministic Quote Verification**: Cited quotes are checked against the raw source text at character-level precision and resolved to canonical `[start, end]` offsets. Sections with evidence terms also expose numbered candidate spans the worker cites by id instead of free-searching; verification recomputes the same span table, so offsets are code-owned. Fabricated or altered quotes fail grounding and trigger immediate route rotation. *(This proves all cited quotes are verbatim source substrings; whether a claim is truly entailed by its quote remains model-generated.)*
2. **Closed JSON Schemas**: Outputs adhere strictly to closed JSON Schemas defined in `TaskSpec`. Models cannot add fields, emit markdown, or drift out of schema.
3. **Derived Scores and Tiers, Not Double Judgment**: Scoring tasks collect an evidence-bound `checklist` of true/false answers, and the pipeline computes `score` (summed points, capped at 100), `fit_tier` (85+ → `tier_1`, 70+ → `tier_2`, 50+ → `tier_3`, else `unfit`), and `passed`. A mismatched derived value fails validation and rotates routes.
4. **Weighted, Time-Decayed Evidence**: Every true answer needs a supporting quote tagged with `supports`, and each answer scores its points scaled by source weight (configurable per-domain rules, longest match wins) and recency decay (per-item half-lives — hiring signals stale in weeks, company fundamentals in months). Untagged truth scores zero, so weak evidence can only lower a score, never inflate one.
5. **Intelligent Route Scoring**: Bayesian-smoothed scoring by verification rate, grounding accuracy, malformed-JSON rate, and latency — not round-robin. Best routes are tried first.
6. **Non-Destructive Rate-Limit Handling**: On `429` or `5xx`, the route is cooled down and the batch is retried immediately on the next lane with **0 attempt burn**.
7. **Rescore Lineage, Not Overwrites**: Fresh evidence arrives as new runs linked by `parent_run_id`; every verified record lands in `score_history`, and `harness-fleet history ENTITY` shows the score trajectory across rounds. Old scores are never rewritten — a stale 40 stays visible next to the new 85 and the evidence that moved it.
8. **Zero-Price Circuit Breaker & Spend Ceilings**: For zero-price runs, pricing is observed from provider receipts; a non-zero charge trips the breaker and disables the route. For paid runs, `--max-request-cost` enforces per-request caps. Cost ceilings fail closed on undeclared pricing.

> **Live proof:** `harness-fleet status <run_id> --watch` streams batch progress and per-route `Verified / Rate limits / Latency`. Fabricated quotes show up instantly as `grounding_failed` and the next lane is tried.

## One-click install

From a fresh checkout, one command sets up everything — no virtual environments or pip to
worry about.

macOS / Linux:

```bash
./install.sh
```

Windows (PowerShell):

```powershell
powershell -ExecutionPolicy Bypass -File install.ps1
```

That one command:

- Creates a private Python 3.10+ environment (`.venv`) and installs `harness-fleet` into it.
- Sets up a workspace at `~/harness-fleet-workspace` and runs the offline demo there.
- Registers the `harness-fleet` MCP tools with Claude Desktop (or Cursor).
- If `OPENROUTER_API_KEY` is set in your shell, passes it into that client config too (values are never printed), so OpenRouter routes work from the desktop app.

Pass a different workspace folder if you want one, e.g. `./install.sh ~/my-harness-workspace`.
Restart Claude Desktop (or Cursor) after it finishes.

---

## Quickstart — 60-Second Demo (No API Keys)

```bash
git clone https://github.com/NatesVibeCode/harness-fleet.git
cd harness-fleet
python3 -m venv .venv
source .venv/bin/activate
python -m pip install .

# Run in your own workspace; output files are written in the current directory.
mkdir my-workspace
cd my-workspace
harness-fleet setup
harness-fleet quickstart --demo --run-id demo-01

# Outputs:
#   runs/demo-01/clean_packet.json   (self-validating packet)
#   runs/demo-01/clean_packet.csv    (flat CSV)
```

On Windows PowerShell, replace the two virtual-environment commands with `py -m venv .venv` and `.venv\Scripts\Activate.ps1`. If activation is restricted, run `..\.venv\Scripts\harness-fleet.exe` directly from `my-workspace`.

The demo uses synthetic scores for ten bundled sample accounts and makes no model API calls. It verifies installation and export, not research quality. Demo routes are excluded from real campaigns unless explicitly selected.

### Real Workspace

```bash
mkdir my-workspace && cd my-workspace
harness-fleet setup --workspace-root . --refresh-routes
```

For a real run, configure one of the seven CLI harnesses (`opencode`, `claude`, `codex`, `cursor`, `grok`, `muse`, `antigravity`) with your own provider access, set `OPENROUTER_API_KEY`, or register a running local model, for example `harness-fleet routes add ollama/your-installed-model --provider ollama --free`. Refreshing routes alone does not authenticate you. `harness-fleet doctor` checks configuration; `harness-fleet test research-demo --input accounts.csv --id-column company --text-column careers_text --provider ollama` tests a real batch before a large campaign.

Each named provider uses its own settings: `OLLAMA_BASE_URL`, `LMSTUDIO_BASE_URL`, `GROQ_API_KEY`, and so on. `OPENAI_COMPATIBLE_BASE_URL` and `OPENAI_COMPATIBLE_API_KEY` configure only `--provider openai_compatible`. Environment variables must be available to the process running the CLI or MCP server; `.env` files are not loaded automatically.

`setup` installs both the account-fleet research skill and the harness-fleet execution skill in the workspace's `.agents/skills` directory. Keep the virtual environment in place when using the generated MCP configuration. Install account-fleet and harness-fleet in separate environments: they share the `harness_fleet` Python package and entry-point names, so one fleet per environment.

### Presets

Create typed tasks instantly with built-in presets:

```bash
harness-fleet init score-demo --preset score             # Evidence checklist + pipeline-derived 0-100 score
harness-fleet init filter-demo --preset filter           # Boolean qualification pass/fail gate
harness-fleet init account-demo --preset account-research # Evidence checklist + derived ICP score/tier + gap extraction
harness-fleet init triage-demo --preset triage           # Priority (high/medium/low) + reason
harness-fleet init classify-demo --preset classify       # Categorical labels + summary
harness-fleet init extract-demo --preset extract         # Named entities + summary
harness-fleet init summarize-demo --preset summarize     # Supported fact summaries
```

Validate and test before launching large runs:

```bash
# Validate task spec and input without making any API calls
harness-fleet validate score-demo --input input.jsonl

# Test a single real batch
harness-fleet test score-demo --input input.jsonl
```

---

## Examples

Runnable starting points live in [`examples/`](examples/) — each folder has a `README.md`, a typed `task.json`, and sample input you can feed straight to `run`:

| Example | Preset | Sample input |
| --- | --- | --- |
| [`examples/account_research/`](examples/account_research/) | `account-research` | `sample_accounts.csv` |
| [`examples/partner_research/`](examples/partner_research/) | `partner-research` | `sample_partners.csv`, `sample_partners_multisource.csv` |
| [`examples/saas_intelligence/`](examples/saas_intelligence/) | `score` | `sample_data.jsonl` |
| [`examples/security_cve_triage/`](examples/security_cve_triage/) | `triage` | `sample_data.jsonl` |

```bash
harness-fleet init my-task --preset partner-research --db ./harness-fleet.db
harness-fleet validate my-task --db ./harness-fleet.db \
  --input examples/partner_research/sample_partners.csv \
  --id-column domain --text-column research --json
```

## Core Capabilities

### 1. CSV In / Scored, Ranked CSV Out
Directly process tabular data and export sorted, ranked deliverables with exact source quotes:

```bash
# Run on CSV specifying ID and text columns (or let harness-fleet auto-detect them)
harness-fleet run score-demo --input accounts.csv --run-id accts-01

# Export ranked deliverable: sorted by score descending, top 25, with 1-indexed rank column
harness-fleet export accts-01 --format csv --sort-by score --desc --top 25 --rank --output ranked_target_accounts.csv
```

### 2. The Compounding Filter (Chaining Layers)
Run multi-stage funnel filtering without running monolithic prompts or wasting model compute:

```bash
# Layer 1: Filter down to survivors
harness-fleet run l1-task --input 1000_candidates.csv --run-id l1
harness-fleet export l1 --format csv --filter '{"all": [{"field": "passed", "value": true}]}' --output l1_survivors.csv

# Layer 2: Only run on survivor IDs from Layer 1
harness-fleet run l2-task --input tech_docs.csv --only-ids l1_survivors.csv --run-id l2
harness-fleet export l2 --format csv --filter '{"all": [{"field": "passed", "value": true}]}' --output l2_survivors.csv

# Final Layer: Score survivors and rank top candidates
harness-fleet run l3-task --input gap_analysis.csv --only-ids l2_survivors.csv --run-id l3
harness-fleet export l3 --format csv --sort-by score --desc --top 25 --rank --output ranked_deliverable.csv
```

Filters compose deterministically at export — a ClaimFilter document with `all`
clauses (AND), `any` branches (OR), and ops `==, !=, >=, <=, >, <, in, not_in`:

```bash
harness-fleet export l3 --format csv \
  --filter '{"all": [{"field": "score", "op": ">=", "value": 70}, {"field": "passed", "value": true}]}' \
  --output qualified.csv
```

Discovery pre-filters mechanically too:
`fetch --title-include engineer --title-exclude manager --exclude-stack mainframe --min-chars 200`.

### 2b. DAG Workflows (multi-stage funnels without CSV round-trips)
Each workflow is a DAG of typed nodes — `run` (one Engine campaign = one SQLite run),
`filter` (deterministic ID sets from a run snapshot), `export` (packet/CSV). Edges carry
IDs and run references in-process, so funnels keep full drill-through (offsets, digests)
at every hop instead of degrading through CSV files:

```json
{
  "name": "funnel",
  "nodes": [
    {"kind": "run", "id": "l1", "task": "filter-task", "input": "candidates.csv",
     "policy": {"allowed_routes": ["demo/fake"], "free_only": true}},
    {"kind": "filter", "id": "l1f", "from_run": "l1",
     "filter": {"all": [{"field": "passed", "value": true}]}, "top": 50},
    {"kind": "run", "id": "l2", "task": "score-task", "input": "docs.csv", "ids_from": ["l1f"]},
    {"kind": "export", "id": "out", "from_run": "l2", "format": "csv",
     "sort": {"field": "score"}, "top": 25, "rank": true}
  ]
}
```

```bash
harness-fleet dag --spec funnel.json --dry-run --json   # validate + print order
harness-fleet dag --spec funnel.json --dag-id campaign-01 --json
```

Node run IDs are deterministic (`<dag-id>-<node-id>`), so re-running resumes completed
`run` nodes from SQLite while `filter`/`export` re-execute. Lineage (spec digest, run IDs,
counts, artifacts) lands in `runs/<dag-id>/dag.json`. Cycles, unknown references, and
wrong-kind edges fail closed at parse time.

### 3. Live Run Monitoring
Track queue progress, worker concurrency, and route-level metrics in real time:

```bash
harness-fleet status <run_id> --watch
```

Output:
```
============================================================
Run: triage-01  |  Task: customer-triage  |  Status: RUNNING
Progress: [=========================>              ] 62.5% (650/1040)
============================================================
Batches:
  Pending:    15
  Leased:      4
  Done:       65
  Failed:      0

Route Performance:
  openrouter:qwen/qwen-2.5-72b-instruct:free
    Attempts: 45 | Verified: 44 | Rate limits: 1 | Latency: 1.2s
  openrouter:meta-llama/llama-3.3-70b-instruct:free
    Attempts: 24 | Verified: 23 | Rate limits: 0 | Latency: 1.8s
```

### 3. Continuous Route Evaluation
Benchmark available routes against test datasets to determine which models excel at your specific task:

```bash
harness-fleet eval customer-triage --input test-samples.csv --id-column id --text-column comment
```

Output:
```
========================================================================================
Route Evaluation Benchmark
Task: customer-triage  |  Samples: 20
========================================================================================
Route                                      Success   Grounding   Score    Avg Latency
----------------------------------------------------------------------------------------
openrouter:qwen/qwen-2.5-72b-instruct:free   100.0%     100.0%    0.982          1.15s
openrouter:meta-llama/llama-3.3-70b-free      95.0%      90.0%    0.871          1.82s
opencode:llama3                               80.0%      85.0%    0.742          2.40s
```
Evaluation benchmarks automatically update route selection priors for subsequent runs.

### 4. Local Models & Generic OpenAI-Compatible Providers
Run bulk workloads completely locally with **Ollama**, **LM Studio**, **vLLM**, or fast cloud inference providers like **Groq** and **Cerebras**:

```bash
# Register your local or custom route in the catalog
harness-fleet routes add ollama/llama3.2:latest --provider ollama --free

# Or configure environment variables
export OPENAI_COMPATIBLE_BASE_URL="http://localhost:11434/v1"
export OPENAI_COMPATIBLE_API_KEY="ollama"
export OPENAI_COMPATIBLE_MODEL="llama3.2:latest"

# Run with local provider selection
harness-fleet run my-task --input data.csv --id-column id --text-column text --provider ollama
```

Endpoints on `localhost` or `127.0.0.1` are automatically marked free (`cost = 0.0`). For third-party cloud OpenAI-compatible endpoints, specify costs explicitly (`--input-cost` / `--output-cost`) or leave them as unknown-cost to prevent accidental misclassification.

### 5. Explicit Data & Privacy Policy
Enforce zero data retention (ZDR), prohibit provider data collection, limit request spend, and control upstream routing on a per-run basis:

```bash
harness-fleet run my-task \
  --input sensitive-data.jsonl \
  --zdr \
  --no-data-collection \
  --provider openrouter \
  --exclude-provider opencode \
  --openrouter-providers Anthropic,Together \
  --max-request-cost 0.05
```

You can pass `--openrouter-providers` as a comma-separated list or as repeatable `--openrouter-provider` flags.

---

## Source Quality

Mechanical `discover` and `fetch` runs enforce a default 70% source-capture
floor and report backend/query provenance for fetched records. Use `--json`
for the `source_quality` report; lower the floor with
`--min-source-coverage 0` only for an intentional sparse-source audit.

## SQLite Control Plane

`harness-fleet` uses SQLite in WAL mode with `BEGIN IMMEDIATE` atomic leases. If a worker crashes or a laptop closes, the run can be resumed seamlessly:

```bash
harness-fleet resume <run_id>
```

Free routes are used by default. A paid route approved in an earlier session must be requested again with `--route <route-id>`.

- **Resumable**: Batches are committed upon verification. Completed work is never repeated.
- **Fault-Tolerant**: Stale worker leases are automatically recovered after timeout.
- **Concurrent**: Multiple worker processes can safely lease batches simultaneously without collisions.
- **Auditable**: Every attempt, model receipt, cost observation, and verification failure is recorded immutably in `inference_attempts`.

## Assistant skills (what installs where)

Skills are the playbooks your AI client reads to drive this CLI. `harness-fleet setup` installs every skill this distribution bundles into `<workspace>/.agents/skills/`, so a connected assistant finds them without you copying anything:

| Skill | Installed as | Drives |
| --- | --- | --- |
| `harness-fleet` | `.agents/skills/harness-fleet/` | This CLI: task contracts, runs, export, MCP, troubleshooting |
| `account-fleet` | `.agents/skills/account-fleet/` | `--preset account-research`: an ICP in, scored target accounts out |
| `partner-fleet` | `.agents/skills/partner-fleet/` | `--preset partner-research`: ecosystem requirements in, scored implementation partners out |

Every skill is plain markdown with a `SKILL.md` plus a `references/` folder (`operations.md`, `task-contracts.md`, discovery playbooks, scoring-rubric guides, MCP recipes). Read them straight from this repo under `skills/`, or preview what setup would install:

```bash
harness-fleet setup --workspace-root "$PWD" --dry-run --json
```

## MCP Server

`harness-fleet` includes a Model Context Protocol (MCP) server for integration into Cursor, Claude Desktop, Antigravity, and other agent environments:

**One-command install (recommended for GTM folks):**
```bash
harness-fleet mcp install --workspace-root "$PWD"  # auto-detects Claude/Cursor, writes mcpServers entry
# Also hand the desktop app a provider key (repeatable or comma-separated)
harness-fleet mcp install --env OPENROUTER_API_KEY
# Preview first
harness-fleet mcp install --dry-run --json
harness-fleet doctor --workspace-root "$PWD" --json  # verify
# Restart Claude/Cursor to load
```

Desktop apps do not inherit your shell environment, so keys such as `OPENROUTER_API_KEY` (or `GROQ_API_KEY`, `OLLAMA_BASE_URL`, …) must be passed explicitly with `--env NAME`; the CLI writes the value into the client config and only ever prints the variable name, never the value. Unset names are skipped with a warning.

Manual entry:
```json
{
  "mcpServers": {
    "harness-fleet": {
      "command": "harness-fleet",
      "args": ["serve", "--workspace-root", "/absolute/path/to/workspace"]
    }
  }
}
```

## Harness Studio (Local UI)

`harness-fleet studio` serves a localhost-only settings companion over the same SQLite
control plane (default `http://127.0.0.1:8080`; honors `--workspace-root`, `--port`, and
`--db`). For a disposable preview workspace, run `scripts/studio_preview.sh`. The page is
read from disk per request, so UI edits only need a browser refresh; Python changes need a
restart.

It is deliberately small: pick harnesses, then pick from *their* models. Runs happen from
the CLI or MCP, which read the same catalogue.

- **Harnesses start off.** Click to include. Each card shows whether its binary is on
  `PATH` and that harness's own login command (`opencode providers`, `codex login`,
  `cursor-agent login`, …) or, for API providers, the environment variable it needs. The
  studio never handles credentials.
- **Models are only listed for what you selected.** `Free models` uses every verified
  `price_observed_zero` route of the selected harnesses; `Specific models` lists their
  models so you choose. Unpriced routes are never picked automatically.

The scoring contract, tasks, and runs are edited through the CLI or an agent — their
endpoints (`/api/tasks`, `/api/tasks/<name>/scoring`, `/api/runs`, `/api/routes/refresh`)
remain available to scripts. The server refuses cross-origin requests so a page you visit
cannot drive it.

```bash
scripts/studio_preview.sh                          # disposable workspace on :8099
harness-fleet studio --workspace-root "$PWD" --port 8080
```

Agents verifying the UI with screenshots: see [AGENTS.md](AGENTS.md) — use playwright,
never raw Chrome, and give pytest runs explicit timeouts.

## Verification & Testing

Run the test suite:

```bash
pytest -q
```

All core components (Bayesian route scoring, SQLite control plane, rate limit cooldowns, OpenAI-compatible provider, CSV IO, real-time status monitoring, and route evals) are covered by automated unit and integration tests.
