What is cross-context?

A command that retrieves a user’s recent activity from other connected platforms.

Use it to look up cross-platform history by user key or person, adjust the time range, or return the unprocessed records.

It supplies missing context when a conversation refers to work discussed somewhere else.

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	$0.00013	$0.00182
Opus 5.5	$0.00005	$0.00073
Sonnet 5.5	$0.00003	$0.00036
Haiku 4.5	$0.00001	$0.00018

Security

Grade A, and why

cross-context 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.

What it actually says

When the user references another platform ("继续昨天那个项目" / "上次我在 Telegram 说过…"), inject context from their other-platform user_keys.

Read the session's user_key from your agent / IM bridge's session data, then:

ccskill context $ARGUMENTS

Typical args:

--user-key <their key> (this person's stable id on the current platform)
--person <name> (if mapped in data/identities.json)
--days 30 (longer lookback)
--raw (skip LLM summary)

No mapping → prints nothing (expected). To map a person on a second platform, edit data/identities.json (see data/identities.example.json).

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.
