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.

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 | $0.00060 | $0.01420 |
| Opus 5 | $0.00030 | $0.00710 |
| Sonnet 5 | $0.00012 | $0.00284 |
| Haiku 4.5 | $0.00006 | $0.00142 |
Grade A, and why
contextdb-autopilot 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 4d 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.

The opening of the file, as written. The whole thing — 129 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ContextDB Autopilot
Working directory: project root. Commands assume repo root; npm run contextdb runs from mcp-server/.
Overview
Use this skill only to persist and retrieve ContextDB state. ContextDB is no longer a prompt-injection layer.
Runtime rules:
- Do not auto-inject ContextDB packets, continuity summaries, persona overlays, user overlays, route guides, or handoff prompts into model prompts.
- Interactive startup may show a short local unfinished-task summary to the user; it must not pass that summary as model input.
- One-shot mode sends only the explicit
--prompttext to the selected client. - Durable workflow constraints belong in checked-in instruction files (
AGENTS.md,CLAUDE.md,GEMINI.md) and repo-local skills.
Deprecated prompt-loading flags are intentionally unsupported:
--startup-mode inject--context-mode--limitCTXDB_AUTO_PROMPT
If old docs, scripts, or user requests mention these as ways to preload memory, treat them as removed behavior. Use explicit search/timeline retrieval instead.
Script path: scripts/ctx-agent.sh
When to Use
- You want cross-CLI memory continuity (
codex,claude,gemini,opencode) in the same project. - You need automatic session creation, event logging, checkpoints, and continuity/handoff artifact writes.
- You want to retrieve prior facts explicitly before continuing work.
Do not use this skill just to execute a normal coding task. Let the current Rex Capability Command select the task Provider.
Required Pattern
Use one-shot mode (--prompt) when you want automatic logging around a single explicit request. The prompt is not augmented with ContextDB state.
scripts/ctx-agent.sh --agent codex-cli --project rex-cli --prompt "继续上次任务，先列出你会读取哪些 handoff 文件"
scripts/ctx-agent.sh --agent claude-code --project rex-cli --prompt "记录这个检查点并总结下一步"
scripts/ctx-agent.sh --agent gemini-cli --project rex-cli --prompt "基于我明确给出的文件继续分析"
scripts/ctx-agent.sh --agent opencode-cli --project rex-cli --prompt "执行这个明确请求，不自动加载历史"
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.

contextdb-autopilot is a skill published in the GitHub repository rexleimo/aios (52 stars, last pushed today), licensed MIT. It adds 60 tokens to every session and 1,420 once invoked, about $0.0003 per session on Opus 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.
