lite-constraints

lite-constraints is a skill for Claude Code from acogood/diffmode_free. It costs 100 tokens per session (2,985 once invoked), scanned A, original, Apache-2.0.

A workflow that creates rules for combining growth factors into unusual but relevant pairs. It reads the current run's growth-factor file and founder context, then writes a JSON constraints file for the synthesis stage.

In plain words
What is it for?
Use it to define allowed combinations, required themes, and combinations to avoid before generating growth tactics.
Why use it?
It guides idea generation away from obvious combinations and prevents references to growth factors that are not available in the current run.

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

lite-constraints 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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 169 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Lite Constraints (synthesis constraints, no Python)

You produce synthesis-constraints.json — the file the synthesis chain reads to force unconventional vector combinations and block conventional ones. In the paid pipeline this is generated by the proprietary Python constraints generator reading the proprietary intelligence layer (curated anchors + internal pair-scoring). Here you reason in-context over the per-run growth-factors.json + founder constraints to emit the same JSON shape. You drop the proprietary intelligence-layer scoring entirely — it was scaffolding for how the script picked pairs, not a field the synthesis prompts consume.

⚠️ Clean-room rule

Build constraints only from this run's growth-factors.json + founder-input.md. Do NOT read anything under tactics_DB/. Every vector ID you reference MUST exist in this run's growth-factors.json — never invent IDs and never use IDs you remember from the proprietary DB. Prohibited-combination rules are expressed at the category / theme level plus generic conventional-outcome patterns (clean-room), not as proprietary specific pairs.

Inputs & Output

  • INPUT (required): WS/03-think-tanks/demand-generation/growth-factors.json (the LIGHT DB — read its vectors and metadata.category_counts).
  • INPUT (required): WS/01-diagnostics/founder-input.md (budget, team size, hours, unfair advantages, stage — to build the founder-leverage pool and bias selection).
  • OUTPUT: write WS/03-think-tanks/demand-generation/synthesis-constraints.json.

What the synthesis chain actually uses (build these fields)

  1. diverse_white_space (explore + build read this) — 8-10 cross-category vector PAIRS that are genuinely unconventional and exclude over-represented "content flywheel"-type vectors. Each: { "vectors": [id_a, id_b], "reason": "<the emergent angle in plain English>", "source": "white_space" }. Pick pairs whose mechanisms, when combined, would make a generic marketer say "that's unusual / risky" (not "obviously do that").

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.

lite-constraints is a skill published in the GitHub repository acogood/diffmode_free (165 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 100 tokens to every session and 2,985 once invoked, about $0.0004 per session on Opus 5.5. 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.
