Hash-anchored read/edit/undo_last_edit tools for DeepSeek Harness (dsh). Every line gets a unique 3-char hash (A-Za-z0-9) that stays stable across edits; stale or ambiguous anchors are rejected, never fuzzy-matched. Undo persists across restarts.
Task-aware two-phase DeepSeek Harness preset: spec/react/weak first-request anchors (bash+read±edit/write), then the full Standard tool catalog after the first tool call.
AI-for-Science research workflow skill bundle for DeepSeek Harness: multi-angle literature review with per-angle files, anchored experiment design with a caveat list, figures, paper reading; cross-verification briefs.
Conversation tick rail and thinking-process fold for the DeepSeek Harness web GUI. Codex-style left rail by default; optional DeepSeek right rail in Settings. Click-to-scroll, eager history load, collapsed Think/tool rows.
DSH Web GUI prompt-based conversation minimap: a vertical navigation rail on the left of long conversations, each anchor = one user prompt; hover shows the prompt preview, click jumps to that message.
Post-compaction premise-drift guard plugin for DeepSeek Harness: after a compaction summary drops a critical literal anchor (path, value, error code) it injects a one-shot notice telling the model what it may have lost and how to recover it from the log
Hash-anchored read/replace/undo tools for DSH. Every line of a file carries a unique 3-char content hash; edits target hashes, never line numbers, so stale anchors are caught before they touch the file. Port of pi-hashline-edit-pro for the Pi coding agent.
Line-anchored read/edit/batch_edit/grep/undo_last_edit tools for DeepSeek Harness (dsh). Every line is addressed by `<line>:<anchor>` so chained edits skip a re-read; stale or ambiguous anchors are rejected and a fresh `<line>:<anchor>` is served back. Undo persists across restarts. Ships a companion web client half rendering hashline-branded read/edit cards.
