Praetorian Plugin

Context guard. Saves and restores valuable context at the right moments — before planning, after research, when subagents complete.

Hooks

Hook	When	Action
PreToolUse(EnterPlanMode)	Before planning	Lists prior compactions, suggests restoring
PreCompact	Before context resets	Prompts to save decisions/insights/findings
PostToolUse(WebFetch/WebSearch)	After web research	Prompts to compact as `web_research`
SubagentStop	After subagent completes	Prompts to compact as `task_result`

Commands

Command	Description
`/compact-praetorian [type] [title]`	Save current context
`/restore-praetorian [query]`	Load previous context

Workflows

Compact (standalone)

Identify what's worth saving (research, decisions, patterns)

praetorian_compact(type, title, key_insights, refs)

Verify with
```
praetorian_restore(title)
```
to confirm it saved

Compact (with siblings)

If historian active:
```
search_plans()
```
to check if past context already covers this
If oracle active: include any tool discoveries in
```
key_insights
```

praetorian_compact(type, title, key_insights, refs)

If vigil active: files are also checkpointed via quicksave

Restore (standalone)

```
praetorian_restore()
```
— list recent compactions
```
praetorian_restore("query")
```
— search for specific topic
Summarize findings for the current task

Restore (with siblings)

```
praetorian_restore("query")
```
— load praetorian context
If historian active:
```
search_conversations("query")
```
for broader session history
If oracle active:
```
search("query")
```
for tools relevant to the restored context
Combine all sources into a unified briefing

Sibling Synergy

Sibling	Value	How
Historian	Past plans surface during planning compactions	`search_plans()` enriches pre-plan hook
Oracle	Tool discoveries included in compactions	Oracle results added to `key_insights`
Gladiator	Observations inform what to compact	Failure patterns highlight important context
Vigil	Files checkpointed alongside context	Quicksave protects files during compaction
