Spec-driven development for Claude Code

Production-ready code from Day 1.

Spec-driven development, enforced. Claude Code writes code fast: TLM Forge makes sure it's correct: a spec audit before any code, independent multi-agent review of your plan and your diff, and a commit gate that won't let work ship until an adversarial red-team pass clears.

The engineering discipline of a senior staff team, enforced on every feature.

Get TLMHow it works
The Problem

It shipped. Nobody checked it.

  • A missing auth check nobody flagged
  • An untested edge case in production
  • A review that never actually happened

TLM Forge checks it before it ships.

Every change gets an independent, adversarial review: a gate, not a best effort.

A GitHub pull request titled "Ship orders when payment succeeds" with the line ship(order) highlighted, and a dotted line from it to a TLM Forge terminal running its Stage 5 final audit, which lifts out a CRITICAL finding from the red-team reviewer: replaying the payment webhook runs ship(order) again with nothing checking the event was already handled, so the order ships twice, citing "payments/webhook.py, line 42" and marked "BLOCKED until resolved".
How It Works

From your request to shipped,
one disciplined pipeline.

After install you manage none of this. TLM Forge hooks into your Claude Code flow: it syncs the architecture and gets your diagram signed off before a line of code is written, then puts the diff through an eight-agent adversarial Review Council before anything ships.

The Memory Layer

It gets sharper the longer it works with you.

TLM's memory layer persists across every session and project: architectural decisions, past bugs, and the conventions it learned the hard way. The proof is spec accuracy: the share of your work TLM anticipated before you wrote it.

Spec Accuracy Over Time

Spec accuracy = what percentage of your work was anticipated by TLM's spec.
The gap is bugs, unplanned features, and missed edge cases. The line goes up because TLM learns from every commit.

What It Enforces

Discipline, enforced:
not politely suggested.

Most tools recommend good practice and hope you follow it. TLM Forge makes the gates mechanical: independent adversarial review, tests-first, and a convergence rule that won't let work ship until critical issues are gone.

Stage 1 · Before any code

Spec audit, every time

Every change starts with an audit of hidden assumptions, threats, and rollback risk, before a line is written.

A feature request titled "Saved cards and payment retries" with requirement 1, "Retry the charge if a payment fails", highlighted, and a dotted line from it to a TLM Forge terminal running its Stage 1 spec audit, which lists six findings (assumptions, threats and rollback risks) and lifts out a CRITICAL finding that says the requirement doesn't say how many times to retry or whether a customer can be charged twice, citing "feature request, item 1" and marked "BLOCKED until resolved".
Stage 2 · Before agents spawn

Design sign-off gate

On Medium and Deep work, you get a flowchart and sequence diagram first: nothing builds until you approve it.

A "Payments webhook" sequence diagram at Stage B showing Checkout, Payments, Webhook and Orders, with a "skip if event seen" guard highlighted, and a dotted line to a TLM Forge terminal showing the Stage B visual diagram gate: the architecture sync and diagram are ready, no agents spawn until approval, then an "approve" command leads to "diagram approved, agents can spawn" and Stage 1 spec audit beginning, with a card confirming the design was signed off with replayed events skipped and nothing built before approval.
Stage 7 · Mechanically

TDD, auditor-enforced

Tests first, RED then GREEN, full regression every phase: enforced by an independent phase auditor, never skippable on a deadline.

Pre-ship · Independent QA

Live verification, end-to-end

A fresh QA agent, never the one that wrote the code, runs it against the real environment before it ships.

A live checkout confirmation page reading "Order confirmed" with a payment history entry of "1 charge, $108.00, Paid" highlighted, and a dotted line to a TLM Forge terminal running its Stage 6 live verification: a fresh QA agent pays with a saved card, pays with a new card, sends the webhook twice, confirms the customer was charged once after a timeout, and confirms the receipt email arrives, with all 12 of 12 checks passing and a card citing the checkout page and payment history as the source of the PASS verdict.
Post-audit · Anti-drift

SHA-anchored commit lock

After the final audit, pushes are blocked if HEAD drifts past the reviewed commit, so no silent changes slip in.

A "git log --oneline" output with the commit "3f9c2a1 verify webhook signature" highlighted below a newer unreviewed commit "8b41e07 retry delay", and a dotted line to a TLM Forge terminal where a "git push" is blocked because HEAD has drifted past the audited SHA to a commit nobody reviewed, with a card citing the final audit's red-team-reviewer verdict and reading "Blocked until Stage 5 re-runs".
Stage 8 · The gate

Convergence gate: ship at zero

A rule counts the real CRITICALs across every review and blocks shipping until they hit zero, with no merging around it.

The Review Council

Eight specialists.
Every gap caught before you ship.

The gates above are staffed by a bench of specialist agents. TLM Forge spawns each one cold, with a single sharp focus: so the threat-modeler isn't swayed by style, and no one reviewer has to catch everything.

Efficient by design

Spec-driven, so it builds on itself: never from scratch.

Each round picks up where the last left off: later reviews verify prior findings instead of re-deriving them, the way a strong engineering team's spec and codebase get sharper over time. That's what lets the full council run on every change, not just the risky ones.

TLM Forge vs the rest

Others structure the work. TLM Forge enforces it.

BMAD-METHOD and GitHub spec-kit help an agent plan. Only TLM Forge blocks the merge until independent, adversarial review says the work is sound.

  • Versioned design diagrams on a GitHub issueThe design gate posts your flow and sequence diagrams as images to a GitHub issue and re-versions them (v1, v2, v3…) as you give feedback: a reviewable design history, with the issue link surfaced every round.
  • Goal contract that runs to completion (/goal)The /goal gate locks the goal, non-goals and measurable exit criteria up front, then keeps building until every criterion is proven, no stopping at 80%, no re-asking "shall I continue?".
  • Optimization for future modelsEvery new Claude model is re-tuned day one: prompts optimized to keep your token usage, and your bill, down.
  • Early access to every new upgradeNew agents, recipes and improvements reach Pro subscribers first.

“This one goes deep, reliably succeeds, and fits just how I need it. I've used it for three major features and every time it surfaced details I missed but were critical to catch. So many footguns avoided — saved me days of work down the road.”
