# Extract Agent Sessions > Extract Agent Sessions is an Agent Skill for documents published in the shareAI-lab/shareAI-skills repository on GitHub: a SKILL.md instruction file an AI agent can load to do this task. Recover, export, or summarize recent human and assistant conversations from local agent session stores while excluding tool calls, reasoning, system injection, copied parent history, and subagent noise. Use for recent-session inventories, clean conversation recovery, or topic summaries from tree-shaped `.claude` and rollout-shaped `.codex` JSONL stores on Linux or macOS. - Skill name: `extract-agent-sessions` - Category: [Documents](https://www.openparable.com/skill/documents/1) - Source: https://github.com/shareAI-lab/shareAI-skills/blob/HEAD/skills/extract-agent-sessions/SKILL.md - Repository: shareAI-lab/shareAI-skills (301 GitHub stars when collected) ## SKILL.md # Extract Agent Sessions Use this skill as a storage map and decision guide, not as a stable parser. Treat all local session layouts as unversioned implementation details. Inspect the files that exist now, adapt shell commands to their observed shape, and fail closed when the shape is ambiguous. Do not create or install a persistent extraction script. Compose one-off commands from the current filesystem and shell capabilities. ## Safety defaults - Treat every session log as sensitive. It may contain source code, personal data, secrets typed by the user, absolute paths, or credentials echoed by tools. - Keep discovery local. Never upload a log or extracted artifact unless the user explicitly asks for that destination. - List candidates as temporary aliases such as `S1` and `S2`. Do not display prompt previews, project names, working directories, complete IDs, or absolute paths by default. Truncation is not redaction. - Read message bodies only after the requested scope identifies the relevant session or the user selects an alias. If content would be sent to another service or person, disclose that boundary and obtain confirmation. - Write private intermediate artifacts only under an owner-restricted temporary directory. Remove them on normal exit and interruption unless the user explicitly requests a private export. - Never inspect authentication files, credential stores, environment snapshots, shell history, debug logs, telemetry, crash dumps, clipboard data, or browser storage for this task. ## Output modes Choose one mode before reading conversation bodies: - **Inventory**: aliases, store family, UTC activity time, transcript availability, state, and warnings. This is the default discovery mode. - **Private full**: every persisted human message and visible assistant text block in order. Keep this owner-only and do not claim to redact it. - **Shareable summary**: themes and outcomes with paths, stable IDs, attachment references, secrets, and unnecessary verbatim text removed. “Lossless” means lossless relative to persisted visible text. Preserve a stored placeholder such as `[Pasted Content ...]` or `[Image #1]` in private-full mode, but state that the externalized body is unavailable. ## Select the shell guidance Resolve the current user's home directory without guessing another user's account. This version supports Linux and macOS hosts: - Read [references/posix-shell.md](references/posix-shell.md) and compose commands for the shell and utilities actually present. - Under WSL, treat the Linux distribution as a separate environment and inspect it only when the agent client ran there. Native Windows session stores are outside this version's supported scope. Read [references/session-layouts.md](references/session-layouts.md) for the relevant store family before selecting identity or message fields. ## Workflow ### 1. Freeze a UTC window Interpret “recent two days” as a rolling 48-hour interval unless the user asks for calendar days. Capture one `[start, end]` snapshot and apply both bounds throughout the scan so new writes do not move the reported window. Use history or visible-message timestamps for discussion recency. Use file size and mtime only to detect active writes or prioritize fallback inspection; never treat mtime as the conversation time. ### 2. Discover from small indexes Inspect keys and timestamp units before filtering the small history indexes. Keep only the latest in-window entry per session ID in a private candidate map. Display anonymous aliases and metadata only. History is a discovery index, not canonical conversation text. It can contain slash commands, local shell commands, or abbreviated pasted content. ### 3. Resolve and prove root identity Resolve transcripts only for selected candidates. Constrain every path to an approved data root, reject symlinks and unsafe IDs, and compare basenames exactly. For tree-shaped stores, accept only root-level project transcripts and exclude every `subagents/` descendant. For rollout-shaped stores, inspect the first projected `session_meta` before reading later records; reject explicit subagents before they can contribute copied parent history. ### 4. Fingerprint the schema without content Project only key names, value types, role/type enums, content-block type names, and counts. Do not print IDs, paths, timestamps, or text values. Collapse unrecognized enum strings to an `unknown-string` marker, then compare the fingerprint to the observed patterns in the reference. If required identity, parent-link, human, or assistant fields are absent or have an unknown combination, stop content extraction and report schema drift. Do not guess which channel contains human-visible text. ### 5. Extract only the selected visible timeline For a tree-shaped transcript, reconstruct the active UUID path before reading text. Use both physical and logical parent links so compacted history remains connected. If the active branch cannot be proven, report the ambiguity instead of merging sibling branches. For a rollout-shaped transcript, preserve canonical human messages and assistant output text. Preserve visible progress and final text in private-full mode, but do not duplicate mirror events. Use lifecycle records only for state. Store attachment presence and counts by default. Preserve local attachment paths or data only when the user explicitly requests a private full export. ### 6. Minimize model context Inspect counts first. For a topic summary, load every selected human message and the final answer for each completed turn. Add visible progress only when a turn has no final answer, is open/aborted, or the store does not label final answers. Keep the complete filtered timeline on disk for private-full mode; do not load all of it into model context merely to produce themes. ### 7. Verify, report, and clean up Compare source identity, size, and modification time before and after extraction. If the source changed, discard the artifact and retry once after it settles. Treat a malformed middle record as corruption; retry an incomplete last line only when the source was actively changing. Report aliases, exact UTC window, root-session count, command-only exclusions, subagent exclusions, state, schema warnings, branch/compact ambiguity, and missing externalized content. Keep original paths and stable IDs only in a private manifest when needed for local traceability. Remove temporary artifacts unless the user explicitly chose a private export path. --- Source: https://www.openparable.com/skill/documents/extract-agent-sessions (OpenParable).
