Read Codex History

Read Codex History

Read Codex evidence only. Do not continue the old task or change its project. If the user wants execution after the read is complete, pass the verified evidence to daymade-claude-code:continue-codex-work.

Codex has three different history surfaces

Do not substitute one surface for another. A prompt-ledger row proves what was submitted, not what the Agent answered. A state DB path is only a candidate until the rollout's session_meta.id matches. A rollout can exist without a prompt-ledger row, and a /fork prompt can exist without a child rollout.

Read references/storage_and_portability.md for source discovery, timestamps, writer-lock semantics, legacy Kimi compatibility, and storage failures. Read references/codex_rollout_format.md before interpreting fork snapshots, compaction, event streams, or end reasons.

Route by the requested result

The requested output wins over the motivation. “Show my recent original inputs” means a chronological raw-input table, not feedback classification, topic mining, an interactive app, or all historical sessions.

For “how many messages/feedback did I give in this conversation; list them verbatim,” read references/user_input_reconciliation.md. Use the reconciler to compose the existing ledger and strict lineage readers. It preserves occurrences, original strings, and source coordinates. Treat exit 2 or complete: false as an incomplete result: scope_input_count: null is not zero, and verified inputs are not a complete total. Review unmatched records against their actual source before supplying any hash-bound injection exclusion. State the counting unit and cutoff; do not call message counts a count of distinct criticisms. Keep ordinary recent-input requests on the ledger-only route.

Commands

Resolve scripts relative to this SKILL.md. Do not rebuild the join with ad-hoc SQLite, Node, jq, or recursive grep.

Recent inventory

<skill-dir>/scripts/list_local_history.py \
  --source codex --cwd <workspace> --limit 20 --language zh

Writer-lock output is positive-only: a held lock proves that exact advisory lock was held during the snapshot. It does not identify the process or prove liveness; an unmarked row does not prove the Session stopped.

Exact original inputs

# Global recent window, then group by Session
<skill-dir>/scripts/list_codex_user_inputs.py --recent 200 --language zh

# Expand exact Sessions already shown, preserving their order
<skill-dir>/scripts/list_codex_user_inputs.py \
  --session-id <ID-1> --session-id <ID-2> \
  --per-session 100 --language zh

Markdown is the human surface; JSON preserves the stored string value for forensic or machine use. Preserve duplicates, line order, timestamps, wording, and Session boundaries. Do not invent titles or split one Session into semantic categories.

Reconciled whole-conversation inputs

<skill-dir>/scripts/reconcile_codex_inputs.py --session <EXACT_ID> --format json

Use --through-record for an explicit inclusive cutoff in the selected session, and --omit-first / --omit-last only for exclusions the user actually requested. Neither option decides whether a message is an opening instruction or feedback. Use --format markdown for literal numbered quotations after resolving gaps. Read the linked reconciliation reference for result fields, reviewed exclusions, partial results, and deterministic fixture-only validation.

Exact Session evidence and lineage

<skill-dir>/scripts/read_codex_session.py --session <SESSION_ID> --full

Expected output: # Codex Session Evidence Briefing, verified selected identity, root-to-child fork lineage, exact parent byte boundaries, chronological handoff, compacted context, latest plan, tool calls, files, errors, end reason, and workspace state. If the state DB points to a rollout with the wrong identity, the reader must reject it and try the exact session_meta.id locator; never continue from the wrong file because its title or filename looked close. When live and archived copies share an ID, the reader accepts byte-identical copies or a strict append-only superset and otherwise fails as ambiguous. Every selected and inherited JSONL record is parsed strictly; malformed lines cannot become a complete-looking receipt.

If the complete briefing is too large for one model context, materialize it once to a private temporary file and record its SHA-256 plus line count before reading. That one immutable file is still the single briefing; “one briefing” does not mean one stdout payload or one monolithic context load. Read bounded, non-overlapping ranges using its existing headings or exact record coordinates, keep coverage against the recorded line count, and report every unread range as a gap. Do not rerun the reader with different truncation and fuse the outputs into a complete-looking chronology.

Bounded full-event search

<skill-dir>/scripts/analyze_sessions.py search \
  --codex-only --all-projects --exclude-session <CURRENT_ID> \
  --from-date <YYYY-MM-DD> --to-date <YYYY-MM-DD> \
  '<keyword-1>' '<keyword-2>'

Start with exact ID, project, date, or known asset names. Broad scans have a stop-loss and must fail visibly rather than present partial results as complete. The exact-ID locator is seconds cheaper than a corpus scan.

Identity and lineage gate

Before making any behavior claim about a named Session:

1. Verify the prompt-ledger Session ID if quoting user input.
2. Locate rollout candidates by their internal session_meta.id, not filename alone.
3. Parse the selected rollout and require session_meta.id == requested ID.
4. For each fork edge, require the declared parent ID and exact history_base.end_byte_offset; reject missing, ambiguous, cyclic, or mismatched ancestry rather than reading the parent's current tail. A legacy rollout with no history_base that inlines its parent's session_meta as the very next record is instead verified record-for-record against the real parent file before its derived byte boundary is trusted.
5. Report prompt-only or rollout-only gaps explicitly.

This gate is the direct correction for two observed cases: a prompt-ledger Session whose state DB pointed at another rollout, and a /fork input with no child rollout.

Read-result contract

Every answer must state:

1. Sources read — prompt ledger, state DB, live/archive rollouts.
2. Coverage — Session IDs, projects, internal time range.
3. Result — the requested raw table, timeline, or matches.
4. Identity/lineage status — verified, prompt-only, rollout-only, or mismatched.
5. Gaps — malformed/unreadable sources, missing parents, omitted attachment bytes, timeouts, or scopes not searched.

“Not found” is scoped to this coverage. Do not call a timeout or incomplete scan a negative result.

Guardrails

• Keep this Skill read-only; it does not resume, archive, rename, delete, or repair.
• Do not run codex resume, codex --continue, or a new implementation experiment.
• Do not load multi-megabyte rollouts directly into context; use the bundled reader.
• Do not infer Session state or ownership from process names, cwd, or writer-lock absence.
• Keep raw history local unless the user explicitly asks to share it.

Router and legacy compatibility

The current local-conversation-history is a cross-provider router; it sends a provider-specific Codex read here and does not replace this Skill's identity, lineage, or evidence contract. The older combined command contract remains in references/legacy_multi_provider_inventory.md so its Kimi branch and historical flags are not silently erased. Provider-specific Claude requests route to daymade-claude-code:read-claude-code-history.
