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 | $0.00038 | $0.01613 |
| Opus 5 | $0.00019 | $0.00807 |
| Sonnet 5 | $0.00008 | $0.00323 |
| Haiku 4.5 | $0.00004 | $0.00161 |
Grade B, and why
bridge-awareness scanned grade B with 1 finding 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 9d 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

Bridge Awareness
You are connected to other Claude Code sessions via the Claude Bridge plugin. This skill defines how you communicate with peer agents.
Getting your session ID: Always use bash "${CLAUDE_PLUGIN_ROOT}/scripts/get-session-id.sh" to get your session ID. This works even if you've cd'd into a subdirectory. In listen mode, use TO_ID from the message output instead (even more reliable).
Querying Peers
When the user asks you to communicate with a peer — whether via /bridge ask, or in natural language like "ask the library about...", "check with the peer", "what did the other session change", etc. — do this:
- Get your session ID. If no bridge exists yet, auto-register first:
Then find connected peers:MY_SESSION=$(bash "${CLAUDE_PLUGIN_ROOT}/scripts/get-session-id.sh" 2>/dev/null) || MY_SESSION=$(bash "${CLAUDE_PLUGIN_ROOT}/scripts/register.sh")
If no connected peers found but the user specified a peer by name or session ID, connect first:find ~/.claude/session-bridge/sessions/$MY_SESSION/inbox -name "*.json" -exec jq -r 'select(.type == "ping") | "\(.metadata.fromProject) (\(.from))"' {} \; 2>/dev/null | sort -uBRIDGE_SESSION_ID=$MY_SESSION bash "${CLAUDE_PLUGIN_ROOT}/scripts/connect-peer.sh" "<peer-id>" - If multiple peers, pick the most relevant one (by project name) or ask the user.
- Send the query and capture the message ID:
MSG_ID=$(BRIDGE_SESSION_ID=$MY_SESSION bash "${CLAUDE_PLUGIN_ROOT}/scripts/send-message.sh" <peer-id> query "Your question here") - Tell the user: "Asking [peer-project-name]..."
- Wait for the response (blocks up to 90 seconds):
bash "${CLAUDE_PLUGIN_ROOT}/scripts/bridge-receive.sh" "$MY_SESSION" "$MSG_ID" 90 - When the response arrives, read it carefully:
- If it's a direct answer, use it to continue the user's task — update code, fix errors, apply migrations, etc.
- If the peer is asking a follow-up question (they need more info from you), answer their question and send a new query with your answer + the original question. Then wait again with
bridge-receive.sh.
- Continue this back-and-forth until you get a final answer, then apply it.
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.

bridge-awareness is a skill published in the GitHub repository PatilShreyas/claude-code-session-bridge (67 stars, last pushed 5mo ago), licensed MIT. It adds 38 tokens to every session and 1,613 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
