Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00000 | $0.00837 |
| Opus 5.5 | $0.00000 | $0.00335 |
| Sonnet 5.5 | $0.00000 | $0.00167 |
| Haiku 4.5 | $0.00000 | $0.00084 |
Grade A, and why
harvester-memory-sync 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 — 93 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Harvester Memory Sync — P4→P2 Bridge
Purpose
Sync trend-harvester's analyzed trends to P2-hippocampus long-term memory. Keeps P2-hippocampus/memories/insights/ in sync with P4-cortex/growth/trend-harvester/ analyzed output.
This closes the P4→P2 downstream flow: trend-harvester output must reach P2-hippocampus/memories/ so the full memory layer benefits from growth insights.
Trigger
- Primary: Run automatically after trend-harvester-001 job completes
- Fallback: Run on-demand via
python3 scripts/harvester_memory_sync.py
Data Flow
P4-cortex/growth/trend-harvester/
collected/ ← raw data (NOT synced)
analyzed/ ← scored trends → COPY to P2 memories
keep/ ← score ≥ 6.0 → insights/YYYY-MM.md
review/ ← 4.0 ≤ score < 6.0 → insights/pending/
graveyard/ ← NOT synced
pending/ ← approved trends → concepts/
applied/ ← applied trends → concepts/ + notes
P2-hippocampus/memories/
insights/ ← trend insights (by date)
concepts/ ← applied concept files
Sync Rules
| Source (P4) | Destination (P2) | Action |
|---|---|---|
analyzed/keep/*.json |
insights/YYYY-MM.md |
Append to monthly insight |
analyzed/review/*.json |
insights/pending/ |
Create pending insight file |
analyzed/graveyard/*.json |
— | Skip (no sync) |
pending/*.json |
concepts/ |
Create/update concept file |
applied/*.json |
concepts/ |
Create/update concept + tag trend-applied |
Anti-Duplication
- Use content hash (MD5 of trend URL or description) as dedup key
- Check if same hash already exists in target before writing
- Track synced hashes in
{{AGENT_NAME_LOWER}}_hidden_state.json["harvester_synced_hashes"]
State Tracking
Read/write from P4-cortex/knowledge/{{AGENT_NAME_LOWER}}_hidden_state.json:

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.

harvester-memory-sync is a skill published in the GitHub repository humanerd-drew/opencode-drewgent (3 stars, last pushed 3mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 837 tokens. 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 2026-08-31.
