tech-deep-dive

A guide for researching and comparing technical choices such as libraries, frameworks, databases, APIs, and software architectures.

In plain words
What is it for?
Use it when selecting or evaluating technology for a particular use case. It can score options, assess their ecosystems, and produce recommendations.
Why use it?
It turns a technology choice into a structured comparison based on stated criteria, ecosystem information, and sources.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

tech-deep-dive scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Technology Deep Dive

Evaluate and compare technologies for specific use cases.

If the requesting agent provides a fixed output contract, keep this evaluation process but deliver the final result in the requested structure instead of the default markdown sections below.

Depth and sources per candidate

Depth When to use Minimum distinct sources per candidate
Standard Typical pick-one or compare-a-few decision ≥ 3 (e.g. official docs + registry + one independent benchmark or reputable article)
Deep High impact, contentious options, or regulatory/security-sensitive choice ≥ 8 across docs, issues, benchmarks, adoption signals, and primary references

If sources fall short, say so explicitly under each candidate and in the recommendation — do not pad with duplicate pages from the same site.

Parallel evaluation

  • After Step 2, plan one stream per candidate (or per evaluation axis if fewer round-trips: e.g. all “license + maintenance” queries in one batch, then all “performance” queries).
  • Run streams in parallel when the runtime allows: batch web_search / web_fetch per candidate rather than finishing A completely before starting B.
  • Merge only in Step 4 — scoring tables and narrative per candidate should be complete before the side-by-side comparison; resolve contradictions during merge.
  • Optional: delegate worker-sized shards (one candidate, fixed headings) via subagents when OpenClaw supports it; the lead turn owns Step 4–5.

Evaluation Criteria

Score each technology on these dimensions (1-5 scale):

Criterion What to Assess
Fitness for purpose Does it solve the actual problem? How well?
Maturity Stable releases, battle-tested, production users
Ecosystem Documentation, community, plugins/extensions, examples
Maintenance health Recent commits, release cadence, maintainer count
Performance Benchmarks, known performance characteristics
API quality Ergonomics, type safety, error handling, learning curve
Integration Compatibility with current stack (Rust, TS, Python)
License OSS license compatibility, commercial restrictions

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

tech-deep-dive is a skill published in the GitHub repository Firstp1ck/pi-coding-agent-forge (74 stars, last pushed 3d ago), licensed MIT. It adds 47 tokens to every session and 1,131 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
