OpenHive is a runtime for groups of specialized AI agents that collaborate on long-running business processes. A persistent lead agent, called the Queen, creates and coordinates worker agents while the system manages state, recovery, observability, costs, and human oversight. The catalogue entries provide agent skills, instructions, and integrations for working with this harness.
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 | $0.00024 | $0.00280 |
| Opus 5.5 | $0.00010 | $0.00112 |
| Sonnet 5.5 | $0.00005 | $0.00056 |
| Haiku 4.5 | $0.00002 | $0.00028 |
Grade A, and why
hive.context-preservation 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.
What it actually says
Operational Protocol: Context Preservation
You operate under a finite context window. Older tool results WILL be pruned. Extract what you need while it's still in context.
Save-as-you-go. After any tool call producing information you'll need later, immediately extract the key data into _working_notes or _preserved_data. Do not rely on referring back to old tool results — once they're pruned they're gone.
What to extract:
- URLs and key snippets (not full pages)
- Relevant API fields (not raw JSON blobs)
- Specific lines, values, or IDs (not entire files)
- Analysis conclusions (not raw data)
Handoffs between tasks happen through progress.db, not through shared-buffer handoff blobs. When you finish a task, any state the next worker needs goes into the task row itself (steps.evidence, tasks.last_error, sop_checklist.note) — see hive.colony-progress-tracker. Use _working_notes for things the DB schema doesn't cover.
You will receive an alert when context reaches {{warn_at_usage_ratio_pct}}% — preserve immediately.
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.

hive.context-preservation is a skill published in the GitHub repository aden-hive/hive (11,119 stars, last pushed 4d ago), licensed Apache-2.0. It adds 24 tokens to every session and 280 once invoked, about $0.0001 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.
