dsx

dsx is a skill for Claude Code, Codex from ain3sh/droid-session-explorer. It costs 52 tokens per session (1,000 once invoked), scanned A, original, MIT.

A command-line search tool for exploring saved Factory Droid sessions, including transcripts, tool calls, token usage, and links between sessions and subagents.

In plain words
What is it for?
Use it to search past sessions, inspect session history, review usage, trace subagent relationships, or investigate whether an earlier session solved a similar problem.
Why use it?
It helps recover useful context from earlier work instead of guessing after a previous tooling, deployment, or operational problem has failed twice.

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.

Security

Grade A, and why

dsx 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 4d 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.

dsx: Droid Session Explorer

dsx indexes every local droid session (~/.factory/sessions) into a fast SQLite+FTS5 index: full transcripts, token usage, tool calls, fork/subagent lineage, and the user's prompt history. The index auto-refreshes before every command (sub-second); add --no-refresh when running many commands in a row.

Every query command supports --json with stable shapes. Prefer it.

When this fires & how to load it

This entrypoint is enough for simple lookups. Load a reference when its trigger fires:

Read When
references/commands.md composing non-trivial queries: full flag surface, FTS5 syntax, JSON hit shapes, export/maintenance commands
references/usage-semantics.md reasoning about costs, tokens, fork inflation, subagents, or droid-exec exclusion
references/stats-analytics.md reasoning about dsx stats cross-tabs, pro-rating, metrics, or distributions
references/insights.md reasoning about dsx insights signal kinds, severity, and report-level rates

Core workflow

Recovery trigger: after two failed attempts at the same operational or tooling problem, stop inventing new hypotheses and search history before a third. Query the exact error or distinctive symptom in the current project, then inspect the best prior session for the proven fix.

  1. Start broad: dsx search "<query>" --json or dsx list --json with filters.
  2. Drill in: dsx show <id> for the shape, dsx export <id> --no-tools for content.
  3. Cite session ids (8-char prefixes are fine) for every claim about past work.
  4. Costs and usage: dsx stats --by model|project|day|day-model|day-project --since 30d. Before attributing cost, read references/usage-semantics.md (fork chains inherit cumulative usage; naive sums double-count).
  5. "What went wrong lately": dsx insights --since 30d.
  6. Record small workflow friction in the moment with dsx papercut add.

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.

dsx is a skill published in the GitHub repository ain3sh/droid-session-explorer (10 stars, last pushed yesterday), licensed MIT. It adds 52 tokens to every session and 1,000 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
