Tech Radar Context

tech-radar-context

Overview

Surface Tikal's opinion on the technologies relevant to the current prompt so a tech stack choice is informed by the Israeli Tech Radar. This skill works like team-discover, but its search surface is the Tikal Tech Radar dataset (fetched live from https://tikalk.com/radar.json) instead of the team CDR index: it extracts candidate technologies from the prompt, matches them against radar blips, and injects a compact Tech Radar Context table (ring, quadrant, Tikal's "Why?" opinion) plus Tikal-aligned alternatives for anything on Stop.

The radar has four quadrants — DevOps, Backend, AI/ML, Web/Mobile — and four adoption rings:

Each blip's description embeds an HTML <p>Why?</p> block followed by a <p>Description</p> block. The Why? text carries Tikal's explicit stance and rationale — that is the opinion to surface. A technology may appear more than once (different quadrants) with different rings; report each relevant placement.

When to Use

Model-invoke this skill whenever the prompt involves choosing or evaluating technology, for example:

• Selecting a framework, library, database, message broker, or cloud tool.
• Comparing options ("X vs Y", "should we use Z").
• Designing a system, service, or pipeline where stack decisions are implied.
• Reviewing an existing stack for modernization or replacement.

Do not invoke it for pure business/product questions with no technology selection, or when the user explicitly says to ignore the radar.

Manual invocation:

/tech-radar-context               # inject radar context for the current prompt
/tech-radar-context redis vs kafka

Core Process

Step 1: Extract Candidate Technologies

From the current prompt (or the description provided by an invoking skill), extract every named or clearly implied technology: languages, frameworks, libraries, databases, brokers, CI/CD tools, cloud services, AI/LLM tooling, build tools, etc. Normalize obvious aliases (e.g. "postgres" → "PostgreSQL", "k8s" → "Kubernetes", "GH Actions" → "GitHub Actions").

If the prompt implies a category without naming a product (e.g. "we need a vector database", "pick a Python web framework"), treat the category as a query and surface the radar's recommended options in that space.

Step 2: Query the Live Radar Dataset

Execute the deterministic search helper script (relative to this skill directory):

POSIX (bash + jq):

bash scripts/radar-search.sh <tech1> [tech2 ...]

Windows (PowerShell):

pwsh scripts/radar-search.ps1 <tech1> [tech2 ...]

Or for JSON output (add --json for bash, -Json for PowerShell).

The script fetches the radar JSON fresh from https://tikalk.com/radar.json, handles alias mapping (k8s → Kubernetes, postgres → PostgreSQL, gh actions → GitHub Actions, etc.), extracts Tikal's <p>Why?</p> opinion, and formats the markdown table automatically.

If a technology appears in multiple placements with conflicting rings (e.g., Node.js is both DevOps: Stop and DevOps: Keep), the script detects and flags it with a Conflicting Guidance note.

Schema of the live radar JSON (https://tikalk.com/radar.json):

{
  "title": "Explore the Tech Radar",
  "quadrants": ["DevOps", "Backend", "AI/ML", "Web/Mobile"],
  "rings": ["Try", "Start", "Keep", "Stop"],
  "blips": [
    {
      "name": "FastAPI",
      "quadrant": "Backend",
      "ring": "Keep",
      "description": "<p>Why?</p>\n<p>...Tikal's opinion...</p>\n<p>Description</p>\n<p>...</p>",
      "isNew": false
    }
  ]
}

Step 3: Match Blips

For each candidate from Step 1, find matching blips by name (case-insensitive, alias-aware, allowing minor version suffixes like "Airflow 2" / "Airflow 3" and partial matches like "Redux" → "Redux Toolkit"). A candidate may match multiple blips across quadrants — keep them all.

For category queries (Step 1), select the strongest radar recommendations in that space: prefer Keep/Start blips in the matching quadrant, and note any Stop blips as things to avoid.

Step 4: Extract Tikal's Opinion

For every matched blip, parse the description HTML:

• The text inside the <p>Why?</p> block (up to the next <p>Description</p>) is Tikal's opinion / rationale — the primary signal.
• The <p>Description</p> block is neutral background — use only if helpful.

Strip HTML tags to plain text and condense the "Why?" to one or two sentences for the context table (quote it more fully when the ring is Stop or when the user is directly weighing that technology).

Step 5: Recommend Alternatives for Stop

When a candidate matches a Stop blip (or is a legacy technology the radar clearly discourages), select Tikal-aligned replacements from the same quadrant on Keep or Start, guided by the "Why?" text. Common examples the dataset supports:

• Airflow 2 → Airflow 3 / Dagster
• Create React App → Vite / Next.js
• Jenkins → GitHub Actions / GitLab CI / Tekton
• requirements.txt / Poetry → uv
• Moment.js / Luxon → day.js / date-fns
• Redux / Redux Toolkit → Zustand / TanStack Query
• Ant Design / Styled Components → Tailwind CSS / shadcn/ui / Radix UI

Do not hardcode substitutions beyond what the loaded dataset supports — derive alternatives from the radar's actual Keep/Start blips in that quadrant.

Step 6: Inject Tech Radar Context (Output Contract)

Emit a Tikal Tech Radar Context section in the visible response, before the task answer, so downstream reasoning is grounded in the radar:

## Tikal Tech Radar Context

| Technology | Quadrant | Ring | Tikal's Opinion (Why?) |
|------------|----------|------|------------------------|
| FastAPI | Backend | Keep | Better alternative to Flask; async, fast, big and growing community. |
| Jenkins | Backend | Stop | Plugin hell + XML config; legacy vs GitHub Actions / GitLab CI / Tekton. |

**Radar guidance**
- ✅ Keep/Start: FastAPI — safe to adopt.
- ⚠️ Stop: Jenkins → consider GitHub Actions, GitLab CI, or Tekton (see Why? above).

_Source: Tikal Israeli Tech Radar (live: https://tikalk.com/radar.json) · N technologies matched._

• One row per matched blip (include duplicates across quadrants when relevant).
• Group a short Radar guidance list: safe-to-adopt vs avoid-with-alternatives.
• Add a _Source_ line noting the data came from the live radar source and how many technologies matched.

If no candidate technology matches any blip, state that plainly with an empty table and a _Source_ line (e.g. _Source: … · 0 technologies matched._) — do not fabricate radar placements.

Failure Handling

• Live fetch fails (network error, timeout, invalid JSON) → the script exits non-zero with a clear error message to stderr. The skill must emit an empty context table noting the Tech Radar source was unreachable and continue the user's task without radar context — never substitute stale cached or bundled data as if it were current.
• No matches → empty table + 0 technologies matched line.

Red Flags

• Fabricating a ring, quadrant, or "Why?" opinion for a technology that is not in the loaded dataset — report 0 matches instead.
• Silently substituting cached, bundled, or stale radar data when the live fetch fails — always report when the radar source is unreachable, never present old data as current.
• Hardcoding Stop→alternative substitutions not backed by the loaded radar.
• Reporting the neutral <p>Description</p> text as Tikal's opinion — the opinion lives in the <p>Why?</p> block.
• Ignoring duplicate blips: the same technology can sit in different quadrants with different rings; surface each relevant placement.
• Treating the skill load as the work — the Core Process must actually run and produce the Tech Radar Context table.

Verification

• Candidate technologies were extracted from the prompt (or category queries formed when no product was named).
• The radar dataset was fetched live from https://tikalk.com/radar.json.
• A Tikal Tech Radar Context table was produced with columns Technology / Quadrant / Ring / Tikal's Opinion (Why?), with the opinion sourced from the <p>Why?</p> block.
• Stop-ring matches include Tikal-aligned Keep/Start alternatives from the same quadrant, derived from the dataset.
• A _Source_ line reports the live-radar source and the match count; a no-match run yields an empty table plus 0 technologies matched rather than fabricated data. On fetch failure, an error is reported and the skill continues without radar context.

Configuration

• Data source: https://tikalk.com/radar.json (live-fetched on every invocation; no bundled snapshot or cache).
• Fetch timeout: 10 seconds. On fetch failure, the skill continues without radar context rather than blocking or substituting stale data.
