SaveContext (MCP)

Save decisions, track progress, and maintain continuity across coding sessions.

Critical Rules

NEVER use context_session_start when the user says "resume". The word "resume" (or "continue session", "pick up where I left off") ALWAYS means:

•context_list_sessions to find the session
•context_session_resume to resume it

context_session_start creates NEW sessions. It has limited auto-resume that only works for active sessions on the exact same project path. Using it to "resume" almost always creates duplicates.

Quick Actions

For most requests, use these patterns directly:

User Says	Do This
"save this decision"	`context_save key="..." value="..." category="decision"`
"remember this"	`context_save key="..." value="..." category="note"`
"checkpoint"	`context_checkpoint name="..."`
"wrap up"	See WrapUp workflow
"resume [topic]"	MUST search sessions, then `context_session_resume`
"start session" / "begin work"	`context_session_start` (new sessions only)

Context Injection

Use context_prime to get full project awareness in a single call.

code

context_prime()                                    # Full context dump
context_prime(smart=true)                          # Relevance-ranked within token budget
context_prime(smart=true, budget=2000)             # Custom token budget
context_prime(smart=true, query="authentication")  # Boost auth-related items
context_prime(smart=true, decay_days=7)            # Aggressive recency bias

Smart mode scores items by temporal_decay * priority * category * semantic_boost, applies MMR diversity re-ranking, and packs into the token budget.

Workflow Routing

Workflow	Trigger	File
QuickSave	"save", "remember", "note this"	`Workflows/QuickSave.md`
SessionStart	Starting work, "begin session"	`Workflows/SessionStart.md`
WrapUp	"wrap up", "end of day", "checkpoint everything"	`Workflows/WrapUp.md`
Resume	"resume", "continue", "pick up where I left off"	`Workflows/Resume.md`
Compaction	"prepare for compaction", context getting long	`Workflows/Compaction.md`
IssueTracking	"create issue", "track this bug"	`Workflows/IssueTracking.md`
Planning	"plan this feature"	`Workflows/Planning.md`
FeatureLifecycle	"implement", "build this", "plan and execute"	`Workflows/FeatureLifecycle.md`
Advanced	Multi-day projects, multi-agent, branch switching, subagents	`Workflows/AdvancedWorkflows.md`

Examples

Example 1: Quick save during work

code

User: "remember that we chose JWT over sessions for auth"
→ context_save key="auth-decision" value="Chose JWT over sessions for stateless scaling" category="decision" priority="high"
→ Saved. No session management needed.

Example 2: Starting a work session

code

User: "let's work on the payment feature"
→ context_session_start name="payment-feature" description="Implementing Stripe integration"
→ Session started (or resumed if exists)

Example 3: Wrapping up

code

User: "wrap up for today"
→ Invokes WrapUp workflow
→ Saves progress, creates checkpoint, pauses session

Do NOT Automatically

•Start sessions for quick saves (just save the item)
•Run multiple tools when one suffices
•Load full reference docs unless user asks how something works
