Individual skill
ctx
Use ctx as working memory for prior agent work. Before starting or continuing work in an unfamiliar area, resuming earlier work, or revisiting an investigation, search prior sessions to ground yourself in earlier context. Use ctx blame to trace a line, file, commit, or PR to the agent session that produced it. Use when prior decisions, constraints, attempts, tool calls, transcript evidence, or code provenance may matter. Use ctx graph queries on indexed projects to follow calls and dependencies and understand what a change might affect.

# ctx
Use ctx to ground your work in relevant prior agent sessions. Search history
for decisions and attempts, trace provenance with blame, and inspect code
relationships with the graph. ctx retrieves evidence; you perform the analysis.
## Choose the operation
- Prior work, decisions or errors: `ctx search "<query>"`.
- Which session produced code: `ctx blame file <path>` or
`ctx blame commit <sha>`; PR targets are also supported.
- Code relationships or potential impact: `ctx graph search <symbol>`,
`ctx graph callers <symbol>`, or `ctx graph impact <symbol>`.
- Requested or explicitly opted-in output compaction: `ctx sift -- PROGRAM
