From 231818cc493383fc4783ada4e9760ee291e00d4c Mon Sep 17 00:00:00 2001 From: Ruslan Strazhnyk Date: Tue, 8 Sep 2026 13:57:37 +0200 Subject: [PATCH 1/2] feat: preserve conversation context across model, effort, and provider switches Keeps one shared conversation when switching between models, effort levels, and backends. A lossless portable transcript is retained separately from the model's compacted working history; CLI backends reuse their native session when available and receive only the turns they missed. - internal/api: ConversationState + per-backend NativeConversation cursors - internal/agent/conversation.go: transcript append/restore, native session sync, budget-aware handoff, searchable JSONL archive for large histories - CLI backends (cc, codex, agy, opencode) record exposed tool activity and refresh effort/output directives on native resumes - sessions: atomic owner-only writes, transcript persistence, --resume and /save/-p support on every backend Retained content is redacted conservatively: it is replayed as the conversation itself, so RedactRetained matches only unambiguous credential shapes rather than reusing the display-time patterns, which rewrote ordinary source like `token := lexer.Next()`. Handoffs abbreviate message bodies instead of dropping whole entries, so advancing a backend's native cursor cannot skip context permanently. Turn counts ignore tool traffic, the context archive is cleaned up on the signal exit paths, /clear rotates to a new session ID instead of overwriting the saved one, and portable transcripts expire after 90 days so session storage stays bounded. Verified: gofmt, go vet ./..., go test ./..., go test -race on agent, session, repl, and codexrunner, plus a release build. --- README.md | 28 +- SECURITY.md | 25 ++ codexrunner/runner.go | 31 ++- codexrunner/runner_test.go | 26 ++ docs/COMMANDS.md | 2 +- internal/agent/agent.go | 48 ++-- internal/agent/agy_agent.go | 6 +- internal/agent/cc_agent.go | 20 +- internal/agent/cerebras_agent.go | 4 +- internal/agent/codex_agent.go | 5 + internal/agent/conversation.go | 364 +++++++++++++++++++++++++ internal/agent/conversation_test.go | 377 ++++++++++++++++++++++++++ internal/agent/ollama_agent.go | 10 +- internal/agent/opencode_agent.go | 53 +++- internal/api/conversation.go | 18 ++ internal/repl/repl.go | 68 +++-- internal/security/security.go | 37 +++ internal/session/conversation_test.go | 167 ++++++++++++ internal/session/session.go | 225 +++++++++++++-- main.go | 70 +++-- 20 files changed, 1462 insertions(+), 122 deletions(-) create mode 100644 internal/agent/conversation.go create mode 100644 internal/agent/conversation_test.go create mode 100644 internal/api/conversation.go create mode 100644 internal/session/conversation_test.go diff --git a/README.md b/README.md index 1d36c79..ccd0787 100644 --- a/README.md +++ b/README.md @@ -395,7 +395,7 @@ configuration keys, and keyboard shortcuts. ## Sessions and automation Interactive sessions auto-save by default.

Four backends carrying a directory and rollout path push the transcript key past byte 1258, well beyond the fixed 512-byte head read, so hasDurableTranscript reported false and the session was expired under the 7-day legacy cutoff instead of the 90-day durable one. Scan the raw bytes in 64KB chunks with an overlap so the key cannot straddle a boundary, and match `"transcript":[` — a populated transcript always serializes with a bracket and a nil one as null, so a single needle distinguishes both cases. Escaped content in a message still cannot match, since it is written as \"transcript\":[.
