Pp Context Dev

Context Dev — Printing Press CLI

Prerequisites: Install the CLI

This skill drives the context-dev-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 context-dev --cli-only
   

2. Verify: context-dev-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 1.26.6 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/ai/context-dev/cmd/context-dev-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.

Agent-friendly Context.dev CLI for website intelligence, brand enrichment, scraping, crawling, structured extraction, screenshots, styleguides, competitor maps, source packs, and change digests.

Command Reference

first-class workflows — Prefer these for common Context.dev operator tasks.

• context-dev-pp-cli scrape <url> --agent — Scrape one URL to clean Markdown.
• context-dev-pp-cli crawl <seed> --max-pages 5 --agent — Crawl same-domain pages. Use --estimate; above 25 pages requires --confirm or --yes.
• context-dev-pp-cli extract <url> --schema schema.json --agent — Extract typed JSON using a JSON Schema file.
• context-dev-pp-cli styleguide <domain|url> --agent — Extract design-system data.
• context-dev-pp-cli screenshot <domain|url> --agent — Capture a screenshot preview.
• context-dev-pp-cli entity-discover --type company --name "<name>" --location "<place>" --agent — Fielded public entity discovery with search, brand/scrape enrichment, ranking, and provenance. Valid types: company, venue, provider, school, agency, other.
• context-dev-pp-cli brand-brief <domain|url> --agent — Normalized brand profile with domain, website, title, description, logo, colors, fonts, socials, contact surfaces, screenshot, summary, and provenance.
• context-dev-pp-cli competitor-map --domain <domain|url> --max 5 --agent — Competitor set clustered by category/market with why_ranked, overlap signals, and provenance. Use --query when no seed domain exists.
• context-dev-pp-cli crawl-budget-plan <seed> --max-pages 25 --agent — Estimate urlRegex, max pages, credits, risks, and recommended crawl command without spending crawl credits.
• context-dev-pp-cli source-pack --query "<query>" --max-sources 5 --agent — Search and scrape cited source packs. Add --schema schema.json to run extraction per source. Search failure is non-zero; zero results are status: "no_results".
• context-dev-pp-cli website-change-digest <domain|url> --agent — Snapshot scrape/styleguide/screenshot in the CLI state dir and diff against the prior local snapshot.
• context-dev-pp-cli schema-lab --url <url> --url <url> --schema schema.json --agent — Run an extraction schema across samples and report field fill rates, parse failures, misses, raw statuses, and provenance.
• context-dev-pp-cli brand-kit <domain|url> --agent — On-demand brand kit (alias: asset-pack): logo, palette, fonts, styleguide, screenshot, favicon, socials, provenance.
• context-dev-pp-cli brand-qa <domain|url> --question "What is the return policy?" --agent — Ask a natural-language question about a brand's website and get a grounded answer with the URLs analyzed and provenance.
• context-dev-pp-cli email-enrich founders@example.com --agent — Turn a work email into a company profile and signup-form prefill fields (company name, website, industry) with provenance.
• context-dev-pp-cli ticker-enrich AAPL --agent — Resolve a public company from a stock ticker or ISIN to a brand profile plus NAICS/SIC industry codes. Auto-detects ticker vs ISIN; pass --exchange to disambiguate a ticker.
• context-dev-pp-cli trust-check <domain|url> --agent — Consistency/risk signal report across website, socials, address, phone, logo, title/domain, and web signals. Do not describe output as fraud determination.
• context-dev-pp-cli lead-enrich-batch leads.csv --domain-column domain --name-column name --location-column location --output enriched.json --resume --agent — Batch-enrich CSV rows with per-row success/error, provenance, and failure reason. Use --strict only when one bad row should fail the batch.

For the second-wave workflows, prefer --agent for machine-stable JSON. Multi-credit commands support --estimate; all workflows support --dry-run. Estimate and dry-run responses contain estimated_credits and planned_requests and do not spend credits. website-change-digest persists snapshots under the resolved CLI state directory, never under the repo. entity-discover rejects free-form blobs and sensitive/person-identifying context; pass only public field values.

Finding the right command

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

context-dev-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.

Auth Setup

Run context-dev-pp-cli auth setup for the URL and steps to obtain a token (add --launch to open the URL). Then store it:

context-dev-pp-cli auth set-token YOUR_TOKEN_HERE

Or set CONTEXT_DEV_API_KEY as an environment variable. CONTEXT_API_KEY is accepted as a fallback when CONTEXT_DEV_API_KEY is unset; the legacy generated CONTEXT_DEV_BEARER_AUTH variable remains supported for compatibility.

Run context-dev-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:

  context-dev-pp-cli brand list --domain example-value --agent --select id,name,status
  

• 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

• Explicit retries — use --idempotent only when an already-existing create should count as success

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 CONTEXT_DEV_HOME=<dir> to relocate all four path kinds under one root.

• Use per-kind env vars only when a specific kind must diverge: CONTEXT_DEV_CONFIG_DIR, CONTEXT_DEV_DATA_DIR, CONTEXT_DEV_STATE_DIR, CONTEXT_DEV_CACHE_DIR.

• Resolution order is per-kind env var, --home, CONTEXT_DEV_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 context-dev-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": {
      "context-dev": {
        "command": "context-dev-pp-mcp",
        "env": {
          "CONTEXT_DEV_HOME": "/srv/context-dev"
        }
      }
    }
  }
  

Fleet precedence: an inherited per-kind env var overrides an explicit --home for that kind. Use CONTEXT_DEV_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 CONTEXT_DEV_HOME, or doctor will not find credentials left under the former root.

Agent Feedback

When you (or the agent) notice something off about this CLI, record it:

context-dev-pp-cli feedback "the --since flag is inclusive but docs say exclusive"
context-dev-pp-cli feedback --stdin < notes.txt
context-dev-pp-cli feedback list --json --limit 10

Entries are stored locally as feedback.jsonl under the resolved data dir. They are never POSTed unless CONTEXT_DEV_FEEDBACK_ENDPOINT is set AND either --send is passed or CONTEXT_DEV_FEEDBACK_AUTO_SEND=true. Default behavior is local-only.

Write what surprised you, not a bug report. Short, specific, one line: that is the part that compounds.

Output Delivery

Every command accepts --deliver <sink>. The output goes to the named sink in addition to (or instead of) stdout, so agents can route command results without hand-piping. Three sinks are supported:

Unknown schemes are refused with a structured error naming the supported set. Webhook failures return non-zero and log the URL + HTTP status on stderr.

Named Profiles

A profile is a saved set of flag values, reused across invocations. Use it when a scheduled agent calls the same command every run with the same configuration - HeyGen's "Beacon" pattern.

context-dev-pp-cli profile save briefing --json
context-dev-pp-cli --profile briefing brand list --domain example-value
context-dev-pp-cli profile list --json
context-dev-pp-cli profile show briefing
context-dev-pp-cli profile delete briefing --yes

Explicit flags always win over profile values; profile values win over defaults. agent-context lists all available profiles under available_profiles so introspecting agents discover them at runtime.

Exit Codes

Argument Parsing

Parse $ARGUMENTS:

1. Empty, help, or --help → show context-dev-pp-cli --help output
2. Starts with install → ends with mcp → MCP installation; otherwise → see Prerequisites above
3. Anything else → Direct Use (execute as CLI command with --agent)

MCP Server Installation

1. Install the MCP server:

   go install github.com/mvanhorn/printing-press-library/library/ai/context-dev/cmd/context-dev-pp-mcp@latest
   

2. Register with Claude Code:

   claude mcp add context-dev-pp-mcp -- context-dev-pp-mcp
   

3. Verify: claude mcp list

Direct Use

1. Check if installed: which context-dev-pp-cli If not found, offer to install (see Prerequisites at the top of this skill).
2. Match the user query to the best command from the Unique Capabilities and Command Reference above.
3. Execute with the --agent flag:

   context-dev-pp-cli <command> [subcommand] [args] --agent
   

4. If ambiguous, drill into subcommand help: context-dev-pp-cli <command> --help.
