tlc-spec-driven

tlc-spec-driven is a skill for Claude Code, Codex from barateza/mcp-plesk-dev-docs. It costs 148 tokens per session (1,069 once invoked), scanned A, original, MIT.

A four-stage method for planning and building software: describe the need, design the solution, split it into tasks, then implement and check the result.

In plain words
What is it for?
Use it to start projects, document an existing codebase, create roadmaps, plan features, and guide implementation with verification criteria.
Why use it?
It turns broad ideas into small, verifiable tasks and keeps project knowledge in files so later sessions can continue with context. It can be used with any technology stack and with both new and existing codebases.

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

tlc-spec-driven 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 4d 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.

Workflow

New project:

  1. Initialize project → PROJECT.md
  2. Create roadmap → ROADMAP.md
  3. Specify features → existing workflow

Existing codebase:

  1. Map codebase → 6 brownfield docs
  2. Initialize project → PROJECT.md + ROADMAP.md
  3. Specify features → existing workflow

Context Loading Strategy

Base load (~15k tokens):

  • PROJECT.md (if exists)
  • ROADMAP.md (when planning/working on features)
  • STATE.md (persistent memory)

On-demand load:

  • Codebase docs (when working in existing project)
  • spec.md (when working on specific feature)
  • design.md (when implementing from design)
  • tasks.md (when executing tasks)

Never load simultaneously:

  • Multiple feature specs
  • Multiple architecture docs
  • Archived documents

Target: <40k tokens total context Reserve: 160k+ tokens for work, reasoning, outputs Monitoring: Display status when >40k (see context-limits.md)

Commands

Project-level:

Trigger Pattern Reference
Initialize project, setup project project-init.md
Create roadmap, plan features roadmap.md
Map codebase, analyze existing code brownfield-mapping.md
Record decision, log blocker state-management.md
Pause work, end session session-handoff.md
Resume work, continue session-handoff.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.
