What is cursor-session-management?

A guide for managing the limited memory available to Cursor Agent and its command-line tool during long conversations.

It covers checking context usage, compressing a conversation manually or automatically, and deciding when to start a fresh chat.

It helps when the agent forgets earlier decisions, the conversation becomes too large, or work needs to continue across several phases.

Token cost

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	$0.00084	$0.00876
Opus 5.5	$0.00034	$0.00350
Sonnet 5.5	$0.00017	$0.00175
Haiku 4.5	$0.00008	$0.00088

Security

Grade A, and why

cursor-session-management 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 2mo 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.

Cursor Session Management

Cursor Agent sessions accumulate messages, tool outputs, rules, MCP definitions, and @ attachments in one shared context window. When the window fills, Cursor summarizes older turns — a lossy compaction distinct from simply starting a new chat. This skill covers monitoring, manual compression, and session hygiene.

When to Activate

Activate this skill when:

The context ring shows high utilization or categorized bloat (tools, MCP, conversation)
Cursor Agent contradicts decisions made earlier in the same chat
Planning multi-phase work (design → implement → test) in one Agent session
Using Cursor CLI and needing to free context with /compress
Deciding between continuing a chat vs opening a new Agent tab

Do not activate this skill for adjacent work owned by other skills:

Do not activate for codebase indexing or semantic search: cursor-context-architecture.
Do not activate for authoring rules that inflate every session: cursor-customization.
Do not activate for platform-agnostic compression algorithms: context-compression.

Core Concepts

Context ring as dashboard

The ring beside the chat input shows fill level. Click it for a breakdown: system prompt, tools, rules, skills, MCP, subagents, summarized conversation, and live conversation. Use this to identify which category is consuming budget — disabling unused MCP servers or shrinking always-on rules often beats re-prompting.

Automatic compression

When the window nears capacity, Cursor compresses older conversation segments into summaries to make room. Summarized content still appears in the tray but loses verbatim detail — tool outputs, exact wording, and fine-grained decisions are the first casualties.

Manual compression (CLI)

Cursor CLI supports /compress to proactively summarize history and reclaim space — use at phase boundaries before starting a new major task, similar to proactive /compact in other agent CLIs.

Changes

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.
