session-start

session-start is a skill for Claude Code from edwin-hao-ai/Awareness-SDK. It costs 19 tokens per session (1,002 once invoked), scanned B, original, Apache-2.0.

A session-start guide for initializing Awareness Memory, loading project context, and creating a session identifier.

In plain words
What is it for?
It is for starting a fresh or continuing memory session, recalling prior context, and using Awareness tools or the local service.
Why use it?
It helps a coding session begin with relevant remembered information and provides a way to track that session.

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.

Security

Grade B, and why

session-start scanned grade B with 2 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 6d 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.

Sends data to an external URLmediumData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

curl -s -X POST http://localhost:37800/mcp -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"awareness_init","arguments":{"source":"claude-code"}}}'

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Initialize Awareness Memory session and load project context.

How to call Awareness tools

Try MCP tools first (awareness_init, awareness_recall, awareness_record, awareness_lookup). If MCP tools are NOT available, use Bash to call the local daemon HTTP API directly:

# awareness_init — fresh session, no prior-session noise (default max_sessions=0)
curl -s -X POST http://localhost:37800/mcp -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"awareness_init","arguments":{"source":"claude-code"}}}'

# awareness_init — resume/continuity mode, include last N session summaries
curl -s -X POST http://localhost:37800/mcp -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"awareness_init","arguments":{"source":"claude-code","max_sessions":3}}}'

# awareness_recall — pass ONE query string, daemon picks the rest
curl -s -X POST http://localhost:37800/mcp -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"awareness_recall","arguments":{"query":"<natural-language question>","limit":10}}}'

# awareness_record — pass ONE content string (action=remember is implied)
curl -s -X POST http://localhost:37800/mcp -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"awareness_record","arguments":{"content":"<detailed description>","insights":{"knowledge_cards":[...],"action_items":[...],"risks":[...]}}}}'

The response is JSON-RPC: result.content[0].text contains the tool output as JSON string.

Steps

  1. Call awareness_init with source: "claude-code".
    • Default mode (fresh session): awareness_init({ source: "claude-code" }) — no prior-session summaries in payload, saves ~500-1000 prompt tokens for brand-new tasks.
    • Resume mode: awareness_init({ source: "claude-code", max_sessions: 3 }) — adds last 3 session summaries for explicit continuity ("continue where we left off").
    • Heuristic: if $ARGUMENTS mentions "continue / resume / yesterday / last time", use resume mode.

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.

session-start is a skill published in the GitHub repository edwin-hao-ai/Awareness-SDK (9 stars, last pushed 4mo ago), licensed Apache-2.0. It adds 19 tokens to every session and 1,002 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it B with 2 findings (sends data to an external url, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
