TeslaTracker — Printing Press CLI

Prerequisites: Install the CLI

This skill drives the teslatracker-pp-cli binary. You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first:

1. Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and %LOCALAPPDATA%\Programs\PrintingPress\bin on Windows:

   npx -y @mvanhorn/printing-press-library install teslatracker --cli-only

2. Verify: teslatracker-pp-cli --version
3. Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill.

If the npx install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.5 or newer). This installs into $GOPATH/bin (default $HOME/go/bin), so add that directory to $PATH instead:

go install github.com/mvanhorn/printing-press-library/library/commerce/teslatracker/cmd/teslatracker-pp-cli@latest

If --version reports "command not found" after install, the runtime cannot see the binary directory on $PATH. Do not proceed with skill commands until verification succeeds.

TeslaTracker aggregates used Teslas across Tesla, Carvana, CarMax and private sellers. This CLI mirrors that inventory into VIN-keyed SQLite and adds the layer the website has no way to offer: a recorded price path per car (price-history), where a price sits in its cohort (comps), how much warranty is genuinely left at delivery (warranty), and which cars quietly left inventory (gone). Every money figure is landed cost, including the real per-car transport fee.

When to Use This CLI

Use this CLI when the question is about used Tesla inventory over time rather than right now: whether a price has moved, how it compares to similar cars, how much warranty remains, or what has left the market. It is strongest after several syncs, because the price series and departure log accumulate locally.

Anti-triggers

Do not use this CLI for:

• Do not use this to control or query a Tesla you already own — that is the Owner/Fleet API, not this.
• Do not use this to buy a car; it has no checkout, no ordering, and no dealer contact.
• Do not treat degradation output as a battery health test; it is the source's published rated-vs-actual spread.
• Do not treat a departure in gone as a confirmed sale; listings can be pulled or reassigned.

Unique Capabilities

These capabilities aren't available in any other tool for this API.

Coverage and condition

• warranty — See exactly how many months and miles of Tesla warranty are left on the day you would take delivery, and which limit runs out first.

  Reach for this when the question is coverage or risk on one specific car, not price.

  teslatracker-pp-cli warranty 5YJ3E1EA7LF745758 --agent

• degradation — Compare a car's actual range against its rated range, and see where that gap sits among every similar car in your local store.

  Use for range condition. This is the source's published spread, not a measured battery test.

  teslatracker-pp-cli degradation 5YJ3E1EA7LF745758 --agent

Price intelligence

• comps — See where one car's landed cost sits in the distribution of comparable cars, with the sample size and the arithmetic shown.

  The honest answer to 'is this price good' — placement and arithmetic, never a verdict.

  teslatracker-pp-cli comps 5YJ3E1EA7LF745758 --agent

• premium — See what a configuration attribute actually costs across the market, computed within matched cohorts.

  Answers 'can I afford HW4 at my ceiling'. Observational, not causal.

  teslatracker-pp-cli premium --by hardwareVersion --agent

• stale — Rank the corpus by days listed and flag cars that are both long-listed and have never had a price cut.

  Finds negotiation candidates. Deliberately does not judge whether the price is good.

  teslatracker-pp-cli stale --limit 20 --agent

• radius — See how the price floor and median change as you widen your search radius, with real transport fees included at every step.

  Answers 'is shopping farther actually worth it' in dollars. Returns a curve, not cars.

  teslatracker-pp-cli radius --lat 30.2241 --lon -92.0198 --agent

Local state that compounds

• gone — See which cars left inventory, at what landed price, and after how many days listed.

  Calibrates a ceiling against what actually clears. A departure is not a sale.

  teslatracker-pp-cli gone --agent

• price-history — See a single car's full observed price path: every cut, its size, and how long it has held the current price.

  Use for one car's own history; use stale to find candidates across the corpus.

  teslatracker-pp-cli price-history 5YJ3E1EA7LF745758 --agent

• watch — Save a named search and see only what is new, price-changed, or departed since the last time you ran it.

  The right entry point for a recurring session instead of re-running search.

  teslatracker-pp-cli watch run --all --agent

Agent-native plumbing

• coverage — See how complete and how fresh your local mirror is, field by field, including whether any pages were dropped during sync.

  Call before asserting any aggregate. Reports on the store, never on cars.

  teslatracker-pp-cli coverage --agent

Command Reference

inventory — Used Tesla listings, VIN-keyed

• teslatracker-pp-cli inventory get —
• teslatracker-pp-cli inventory list —
• teslatracker-pp-cli inventory report —

Freshness Contract

This printed CLI owns bounded freshness only for registered store-backed read command paths. In --data-source auto mode, those paths check sync_state and may run a bounded refresh before reading local data. --data-source local never refreshes. --data-source live reads the API and does not mutate the local store. Set TESLATRACKER_NO_AUTO_REFRESH=1 to skip the freshness hook without changing source selection.

Covered paths:

• teslatracker-pp-cli inventory
• teslatracker-pp-cli inventory get
• teslatracker-pp-cli inventory list
• teslatracker-pp-cli inventory search

When JSON output uses the generated provenance envelope, freshness metadata appears at meta.freshness. Treat it as current-cache freshness for the covered command path, not a guarantee of complete historical backfill or API-specific enrichment.

Finding the right command

When you know what you want to do but not which command does it, ask the CLI directly:

teslatracker-pp-cli which "<capability in your own words>"

which resolves a natural-language capability query to the best matching command from this CLI's curated feature index. Exit code 0 means at least one match; exit code 2 means no confident match — fall back to --help or use a narrower query.

Recipes

Rank the corpus by how long cars have been sitting

teslatracker-pp-cli stale --limit 20 --agent --select vin,model,year,mileage,landed_usd

Ranks the local mirror by days listed, with landed cost attached. Staleness is a negotiating signal, not a price judgement — a car can sit simply because it is overpriced, so pair a VIN from here with comps before making an offer.

Full-text search the local mirror

teslatracker-pp-cli search "model 3 long range" --limit 20 --agent

FTS5 over everything synced, offline, no API call.

Is this price defensible?

teslatracker-pp-cli comps 5YJ3E1EA7LF745758 --agent

Returns the percentile, the median, the dollar gap and the sample size — never a bare score.

How much car is left

teslatracker-pp-cli warranty 5YJ3E1EA7LF745758 --annual-miles 12000 --agent

Months and miles remaining at delivery, naming whichever of the four limits binds first.

What did I miss since yesterday

teslatracker-pp-cli watch run --all --agent

New, price-changed and departed since each saved search's own cursor.

Does the HW4 premium fit my budget

teslatracker-pp-cli premium --by hardwareVersion --agent

The landed-price difference between hardware versions within matched model/year/trim cohorts, with n per cell.

Auth Setup

No authentication required.

Run teslatracker-pp-cli doctor to verify setup.

Agent Mode

Add --agent to any command. Expands to: --json --compact --no-input --no-color --yes.

• Pipeable — JSON on stdout, errors on stderr

• Filterable — --select keeps a subset of fields. Dotted paths descend into nested structures; arrays traverse element-wise. Critical for keeping context small on verbose APIs:

  teslatracker-pp-cli inventory list --agent

• Previewable — --dry-run shows the request without sending

• Offline-friendly — sync/search commands can use the local SQLite store when available

• Non-interactive — never prompts, every input is a flag

• Read-only — do not use this CLI for create, update, delete, publish, comment, upvote, invite, order, send, or other mutating requests

Response envelope

Commands that read from the local store or the API wrap output in a provenance envelope:

{
  "meta": {"source": "live" | "local", "synced_at": "...", "reason": "..."},
  "results": <data>
}

Parse .results for data and .meta.source to know whether it's live or local. A human-readable N results (live) summary is printed to stderr only when stdout is a terminal AND no machine-format flag (--json, --csv, --compact, --quiet, --plain, --select) is set — piped/agent consumers and explicit-format runs get pure JSON on stdout.

Paths and state

Agents should treat the CLI's path resolver as part of the runtime contract:

• Use --home <dir> for one invocation, or set TESLATRACKER_HOME=<dir> to relocate all four path kinds under one root.

• Use per-kind env vars only when a specific kind must diverge: TESLATRACKER_CONFIG_DIR, TESLATRACKER_DATA_DIR, TESLATRACKER_STATE_DIR, TESLATRACKER_CACHE_DIR.

• Resolution order is per-kind env var, --home, TESLATRACKER_HOME, XDG (XDG_CONFIG_HOME, XDG_DATA_HOME, XDG_STATE_HOME, XDG_CACHE_HOME), then platform defaults.

• config contains settings like config.toml and profiles. data contains credentials.toml, data.db, cookies, and auth sidecars. state contains persisted queries, jobs, and teach.log. cache contains regenerable HTTP/cache files.

• Stored secrets live in credentials.toml under the data dir. Existing legacy config.toml secrets are read for compatibility and leave config.toml on the first auth write.

• Run teslatracker-pp-cli doctor --fail-on warn to surface path and credential-location warnings. agent-context exposes a schema v4 paths block for agents that need the resolved dirs.

• For MCP, pass relocation through the MCP host config. The MCP binary does not inherit CLI flags:

  {
    "mcpServers": {
      "teslatracker": {
        "command": "teslatracker-pp-mcp",
        "env": {
          "TESLATRACKER_HOME": "/srv/teslatracker"
        }
      }
    }
  }

Fleet precedence: an inherited per-kind env var overrides an explicit --home for that kind. Use TESLATRACKER_HOME or per-kind vars as durable fleet levers, and use --home only for a single invocation. Relocation is not reversible by unsetting env vars; move files manually before clearing TESLATRACKER_HOME, or doctor will not find credentials left under the former root.

Automatic learning

This CLI ships a self-capturing learning loop. The CLI does its own bookkeeping: every invocation is journaled locally, a failed flag followed by a corrected retry auto-derives a flag_alias candidate, and a teach on a query family without a playbook auto-synthesizes a playbook_candidate from the session's journal. Your job is judgment only: recall first, act on surfaced candidates, teach the final answer, playbook amend when you observe a correction. You never record failures by hand.

Step 1: recall before any discovery

Before list/search/drill commands on a new user question, run:

teslatracker-pp-cli recall "<user's question>" --agent

The response envelope:

{
  "query": "...",
  "normalized": "<normalized form>",
  "query_entities": ["..."],
  "found": true | false,
  "match_score": 0.0,
  "results": [
    { "resource_id": "...", "resource_type": "...", "venue": "...",
      "confidence": 2, "entity_match": "exact|partial|unknown",
      "source": "taught|preseed|pattern", "warnings": ["..."] }
  ],
  "mismatches": [ /* only when --debug-mismatches */ ],
  "warnings": [ /* top-level */ ],
  "candidates": [
    { "id": 12, "class": "flag_alias | playbook_candidate",
      "summary": "...", "sightings": 3, "last_seen": "...",
      "rationale": "...",
      "next_action": ["<trial command>", "teslatracker-pp-cli learnings confirm 12"] }
  ],
  "playbook": {
    "query_family": "...",
    "playbook": {
      "steps": [ { "cmd": "<command with {slot} substitution>", "purpose": "..." } ],
      "entity_slots": ["$ENTITY"],
      "expected_tool_calls": 3
    },
    "slots_resolved": { "$ENTITY": { "token": "<live token>", "canonical": "<canonical>" } },
    "notes": "<workarounds + gotchas for this query family>"
  },
  "notes": "<duplicate surface for non-playbook callers>"
}

Empty-store short-circuit: if the store has no learnings, playbooks, or candidates yet (recall finds nothing and learnings list and learnings candidates are both empty), skip recall for the rest of this session instead of taxing every query; resume recall-first once something has been taught.

Step 2: decision tree

Read candidates, playbook, notes, results[0], and warnings in that order:

if Candidates present (warnings include "candidates_present"):
    -> candidates are try-then-confirm, never facts. Follow each candidate's
       two-step next_action verbatim: run the trial command first, then run
       `learnings confirm <id>` only after the trial verified the behavior.
       Reject a wrong candidate with `learnings reject <id>`.
    -> NEVER re-teach something recall surfaced as a candidate; confirm or
       reject that candidate instead of teaching a duplicate.
    -> candidates ride alongside playbooks and resource hits, not instead of
       them; continue with the branches below after acting on them.

if Playbook present:
    -> READ Playbook.notes verbatim FIRST (workarounds + gotchas the CLI surface doesn't expose)
    -> replay Playbook.steps in order, substituting Playbook.slots_resolved entries
       for the entity slot tokens. If a step's slot is unresolved, fall back to
       discovery for that step only.
    -> the Playbook's expected_tool_calls is a budget; if you find yourself running
       materially more, record the divergence via `teslatracker-pp-cli playbook amend`
       at end-of-session.

elif Notes present (no Playbook):
    -> read Notes verbatim before any discovery step; they carry known gotchas
       for this query family even when no structured choreography exists yet.

elif Found AND Results[0].EntityMatch == "exact" AND Results[0].Confidence >= 2:
    -> skip discovery; fetch live data for Results[*].ResourceID in parallel

elif Found AND Results[0].EntityMatch == "partial":
    -> candidate hint, NOT a hit; read the resource title to validate before trusting

elif (any row in Mismatches[] when --debug-mismatches was passed):
    -> treat as cold start; the stored learning is for a different entity
       (different canonical resolved from query_entities)

else:  // Found == false, no playbook, no notes
    -> cold start; run discovery normally; teach the answer afterward (Step 4).
       If the family has no playbook yet, that teach auto-synthesizes a
       playbook candidate from this session's journal - you do not need to
       record one by hand.

Playbook and Notes are orthogonal to the per-resource path. A recall response can carry both a Playbook AND a Results[] hit - use both: the Playbook tells you which choreography to run; the resource hits short-circuit specific steps. Default to skipping mismatches; pass --debug-mismatches only when investigating cold-start surprises.

Candidate judgment details: learnings confirm <id> prints the candidate's full payload before materializing it - check that the printed payload matches the behavior you verified. learnings reject <id> tombstones the derivation signature so the same candidate does not resurface. The envelope carries only the few candidates worth acting on now; teslatracker-pp-cli learnings candidates lists the full open set.

Graceful degradation: if learnings confirm is an unknown command, you are driving an older binary - ignore the candidates guidance and follow the rest of the protocol.

Step 3: always read warnings

• low_confidence: row exists at confidence<2. Treat as a hint, not a skip-discovery hit.
• resource_not_in_store: the local store doesn't have the resource the learning points at. The match validator couldn't classify entities — direct-fetch and re-evaluate.
• cross_alias_match (per-result): the row was taught under a different alias and matched the live query's canonical via entity_lookups (e.g., a "USA" teach satisfying a "United States" recall). Trust the resource_id.
• similar_shape_different_entity:<canonical> (top-level): a structurally matching row exists but its canonical entity differs from the live query's. Treated as cold start; the warning carries the conflicting canonical as a hint, but the row is NOT promoted into Results.
• ambiguous_alias (top-level): a single query entity resolved to multiple canonicals (e.g., "Cards" → Arizona Cardinals + St. Louis Cardinals). Surface the ambiguity from context before committing to a resource.
• candidates_present (top-level): the envelope carries a candidates section. Handle it via the candidates branch in Step 2 before anything else.
• lookup_refresh_available (top-level): an entity in the query has no lookup row yet, but synced data could provide one. Run teslatracker-pp-cli sync to refresh entity lookups.
• Top-level no_learnings_for_query_family: the table had no rows above the Jaccard floor. Pure cold start.
