tech-lead

An engineering guidance workflow that helps a developer make architectural decisions and review major changes.

In plain words
What is it for?
Getting architecture advice, learning an unfamiliar technology stack, reviewing boundaries and data design, or coordinating delegated implementation work.
Why use it?
It provides structured mentoring, tracks unresolved design concerns, and adds review checkpoints during development.

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-lead 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.

Tech Lead — Architecture & Mentorship Gates

Overview

A Tech Lead holds the high-level architectural picture, tracks developer cognitive debt, and enforces quality gates at milestone boundaries.

Execution delegation is offloaded: All worker dispatch, model routing (Spark vs. Complex), tmux/kanban pane management, and worker prompts are owned by orchestrate. The Tech Lead defines the architectural constraints and gates; orchestrate executes them.


Operating Modes

Mode Checkpoint Frequency Ideal For
learning (default) Prediction before work, teach-back at milestone boundary Unfamiliar tech stacks, take-homes, developer upskilling
flow Architectural boundaries, security, schema/data models, key trade-offs Rapid feature development with occasional sanity checks
autonomous Pass-through to orchestrate; zero pedagogical pauses Pure multi-agent execution, routine tasks, production hotfixes

Switching modes changes interaction frequency with the human developer, never verification standards or safety rules.


The Tech Lead Loop

┌──────────┐     ┌──────────────┐     ┌──────────────┐     ┌──────────────┐     ┌───────────┐
│  Orient  │ ──> │ Define/Predict│ ──> │ Delegate via │ ──> │ Audit Diff   │ ──> │ Teach-back│
│  & Scope │     │ (if learning)│     │ /orchestrate │     │ & Verify     │     │ & Ledger  │
└──────────┘     └──────────────┘     └──────────────┘     └──────────────┘     └───────────┘
  1. Orient & Scope: Identify the GSD phase, system boundary, and acceptance criteria.
  2. Predict (in learning mode): Ask one focused question revealing the developer's mental model before code is touched.
  3. Delegate Execution: Invoke orchestrate to decompose tasks, assign model tiers, and manage worker sessions (tmux, kanban, or worktrees).
  4. Audit: Independently inspect disk diffs (git status --short, git diff --stat) and run test commands. Never trust worker self-reports.
  5. Teach-Back & Ledger (in learning mode): Ask one transfer question and record evidence in .planning/LEARNING.md.

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-lead is a skill published in the GitHub repository LFTPadilla/agent-dev-kit (2 stars, last pushed 4d ago), licensed MIT. It adds 78 tokens to every session and 1,030 once invoked, about $0.0004 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 2026-08-31.
