timeline

timeline is a skill for Claude Code, Codex from Generous-Corp/pulp. It costs 86 tokens per session (41,826 once invoked), scanned A, original, MIT.

Build, edit, validate, explain, render, import, or integrate Pulp timeline projects through the CLI, MCP tools, or C++ SDK. Use for sequencers, arrangements, clips or notes, tempo and meter maps, automation, takes and comps, freeze, capture-to-timeline workflows, durable journals, project persistence, DAWproject…

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

timeline 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 today.

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.

Timeline document model

Choose the surface

  • Use MCP for agent-driven project inspection, command application, diff, undo/redo, validation, explanation, render, export, and import. Its ten operations are pulp_timeline_project_open, pulp_timeline_command_apply, pulp_timeline_diff, pulp_timeline_undo, pulp_timeline_redo, pulp_timeline_validate, pulp_timeline_explain, pulp_timeline_render, pulp_timeline_export, and pulp_timeline_import. Seven operations retain stateless pulp::tool-timeline entry points; diff, undo, and redo are MCP-local operations backed by a live DocumentSession.
  • Use /seq for the agent-guided inspect, validate, edit, explain, import, and consent-gated export workflow. Use pulp seq and pulp render directly for shell scripts, CI, and human-operated headless workflows. Prefer seq apply with typed command envelopes over inventing one-off mutation flags.
  • Use the C++ SDK when embedding an editor, transport, compiler, renderer, recorder, or durable session. Keep document mutation in DocumentSession, playback derivation in PlaybackProgramCompiler, realtime rendering behind immutable programs and transport snapshots, and capture publication as ordinary timeline commands. A ProgramCompileRequest must declare its exact sample_rate explicitly and carry a CompiledTempoMap built at the same normalized RationalRate; omission or disagreement is a synchronous invalid request rather than an inferred default.
  • Link Pulp::timeline-agent-view when an agent or remote client needs a bounded, deterministic projection of one pinned DocumentView. AgentView exposes a committed outline, cursor-paged clip regions, and a projection of one adjacent commit's DirtySet without widening the dependency-minimal Pulp::timeline model.
  • Link the optional Pulp::dawproject-import SDK target only when ingesting DAWproject XML, and Pulp::smf-interop only when reading or writing Standard MIDI Files; keep the dependency-minimal model on Pulp::timeline.
  • Use the generated schema surfaces to discover command/document shapes; do not hand-copy schema vocabularies into a client.

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.

timeline is a skill published in the GitHub repository Generous-Corp/pulp (16 stars, last pushed today), licensed MIT. It adds 86 tokens to every session and 41,826 once invoked, about $0.0004 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 2026-09-04.
