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

decision-logger 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 today.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/decision_tracker.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 155 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Decision Logger

Two-layer memory system. Layer 1 stores everything. Layer 2 stores only what the founder approved. Future meetings read Layer 2 only — this prevents hallucinated consensus from past debates bleeding into new deliberations.

Keywords

decision log, memory, approved decisions, action items, board minutes, /decision-logger decisions, /decision-logger review, conflict detection, DO_NOT_RESURFACE

Quick Start

python scripts/decision_tracker.py --demo             # See sample output
python scripts/decision_tracker.py --summary          # Overview + overdue
python scripts/decision_tracker.py --overdue          # Past-deadline actions
python scripts/decision_tracker.py --conflicts        # Contradiction detection
python scripts/decision_tracker.py --owner "CTO"      # Filter by owner
python scripts/decision_tracker.py --search "pricing" # Search decisions

Commands

Command Effect
/decision-logger decisions Last 10 approved decisions
/decision-logger decisions --all Full history
/decision-logger decisions --owner CMO Filter by owner
/decision-logger decisions --topic pricing Search by keyword
/decision-logger review Action items due within 7 days
/decision-logger review --overdue Items past deadline

Two-Layer Architecture

Storage follows the canonical two-layer decision memory (see ../agent-protocol/SKILL.md → "Decision Memory (Canonical Layout)") — the same layout /c-level-agents:decide writes.

Layer 1 — Raw Transcripts

Location: ~/.claude/decisions/raw/YYYY-MM-DD-<slug>.md

  • Full Phase 2 agent contributions, Phase 3 critique, Phase 4 synthesis
  • All debates, including rejected arguments
  • NEVER auto-loaded. Only on explicit founder request.
  • Archive after 90 days → ~/.claude/decisions/raw/archive/YYYY/

Layer 2 — Approved Decisions

Location: ~/.claude/decisions/approved/ — one record per decision (YYYY-MM-DD-<slug>.md) plus the append-only index decisions.md

  • ONLY founder-approved decisions, action items, user corrections
  • Loaded automatically in Phase 1 of every board meeting
  • Append-only. Decisions are never deleted — only superseded.
  • Managed by Chief of Staff after Phase 5. Never written by agents directly.

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
