AI CODING AGENT · v0.2.54
8-Gate Authorization Protocol

The Agent That Earns the Right to Write Code.

Every other AI writes first and breaks things later. ThreadLion passes 8 intelligence gates — understanding, mapping, risk, and strategy — before touching a single file. No authorization, no edit.

The Real Problem

AI writes fast. It just doesn't earn the right.

The problem isn't the model — models are fast, cheap, and capable. The problem is that no agent asks permission before modifying your code. They just write, and you clean up the mess.

Problem 01

AI that misunderstands requirements

Most AI coding mistakes aren't model errors — they're comprehension failures. The agent builds something technically correct that solves the wrong problem entirely.

Problem 02

Coding without context

AI that jumps to code before mapping your codebase produces solutions that work in isolation but break your architecture — reinventing, duplicating, or contradicting your patterns.

Problem 03

Low-confidence edits in production

Speed-optimized AI writes first and asks questions never. When it's wrong, it compiles cleanly, passes basic tests, and ships to production before anyone notices.

The Solution

Three phases. Zero guessing.

Every coding task passes through the same mandatory sequence — understand first, validate before writing, verify after. No shortcuts, no silent failures.

1

Understand

The agent reads your codebase, maps every dependency, traces all callers, and builds a complete picture before forming any opinion about what to change.

outline → find_symbol → read
2

Validate

8 intelligence gates score understanding, repository coverage, risk, scope, and strategy. Authorization is a numeric score — anything below threshold blocks execution.

Auth Score ≥ 85 required
3

Execute

Only once authorized does the agent write code. Edits are scoped to declared files only. Syntax validation runs automatically afterward.

validate_syntax → verify
Intelligence Protocol

The agent that earns the right to write code.

Other agents write first and apologize later. ThreadLion works differently — every request passes through 8 intelligence gates. Fail a gate and the agent is blocked, not guessing. It investigates, rescores, and retries until it earns authorization. Only then does it touch your code.

Read-only by default
Every session starts locked. No file can be modified until authorization is granted — enforced in code, not prompts.
STATE = READ_ONLY
8 intelligence gates
Understanding, repository mapping, minimal change proof, strategy, and risk — all scored 0–100 before any edit.
Auth Score 0–100
Fails fast, retries smart
Any gate below threshold blocks immediately and tells the agent exactly what's missing. It investigates, rescores, and retries.
Gate N FAIL → retry
File-level authorization
Only files declared upfront may be modified. The agent cannot touch anything outside its declared scope.
MODIFY_ALLOWED: path
Why Developers Trust It

Built for production engineering.

Every feature is designed for teams who cannot afford silent failures — engineering teams shipping to real users.

Understanding-first workflow

The agent cannot write code until it has demonstrated understanding of your codebase structure, the affected symbols, and every caller in scope.

UNDERSTAND BEFORE WRITE

Context validation engine

Automatic codebase mapping before every task. Repository score must reach 80/100 or the agent gathers more context before proceeding.

REPO SCORE ≥ 80

Confidence-based gates

Authorization is a computed score from 8 weighted factors. The agent meets the threshold or is blocked — no prompt-only enforcement.

SCORE COMPUTED IN CODE

Safe autonomous edits

Files are declared before the session writes to them. The agent cannot discover an improvement mid-task and silently apply it — scope is locked at authorization time.

FILE SCOPE LOCKED

Multi-step reasoning

Each task generates a plan, verifies it against your codebase, and reviews the result after writing. Full auditability at every step.

PLAN → EXECUTE → VERIFY

Production-ready verification

Syntax validation and type checking run after every file write. Nothing is marked complete until the source is clean.
