Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00100 | $0.02985 |
| Opus 5.5 | $0.00040 | $0.01194 |
| Sonnet 5.5 | $0.00020 | $0.00597 |
| Haiku 4.5 | $0.00010 | $0.00298 |
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 itsvectorsandmetadata.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)
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").
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.

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.
Other skills, from other repositories
newsjack-detector
Monitor current news and reaction signals, then decide which are credible newsjacking opportunities for a client. Uses the local monitoring engine for evidence, but the skill owns PR judgment, brand safety, standing, decay, angle fit, and handoff.
crisis-holding
Draft crisis holding statements, journalist Q&A posture, and what-not-to-say guidance from confirmed incident facts, with a hard legal-counsel gate. Builds each statement through proven crisis-comms frameworks (holding-statement anatomy, SCCT, CAP order, the legitimate non-answer, bridge/flag/block).
voice-extractor
Capture a user's real writing voice from 5-20 prior samples, store a local voice.yaml fingerprint, and enforce it on newsjack drafts so AI tells disappear. Measures voice with named stylometry lenses (Burrows's Delta function-word vector, MATTR lexical diversity, sentence-length burstiness, Biber Dimension-1 register…
fact-check
Extract factual claims from PR copy, verify each claim independently, attach concrete citations, and warn when certainty is low. Runs each claim through proven newsroom verification methods (lateral reading, source-tier climbing, provenance pillars, triangulation, calibrated rating) and puts the burden of proof on the…
find-journalists
Build a researched, fit-checked journalist list for a specific PR campaign. Prefer Medialyst's asynchronous media-list research workflow when available, with explicit approval before credit spend; otherwise produce a best-effort local list without guessed contacts.
pr-calendar
Turn the Medialyst PR calendar feed into a brand-specific, lead-time-aware plan. Pull source-backed upcoming moments, keep only the few a brand has real standing to own, schedule backward from the event date, screen out tone-deaf hooks, and hand selected moments to angle and journalist prep ahead of time. The planned…
