* feat(cli): pad session shape — Claude Code context-window telemetry (IDEA-1491)
New `pad session shape [--session <id|path>] [--format json|table|markdown]`
command that reads the active Claude Code session JSONL and reports tokens,
context_pct (vs hardcoded per-agent-version budget), message counts, and
elapsed time. Default format is JSON because agents are the primary caller.
- internal/cli/claudecode.go: project-slug derivation, JSONL streaming
parser, env/cwd/autodetect cascade resolver, per-version budget table
(seeded with 2.1.* → 1M tokens per the IDEA-1491 recon update).
- cmd/pad/session.go: top-level `session` group + `shape` subcommand,
three output formats, registered via cmd/pad/main.go's rootCmd.
- Tests cover slug derivation (live ~/.claude/projects/ verified cases),
JSONL parse (normal / no-usage / sidechain fixtures), budget lookup,
context-class bucketing, and the resolver cascade in t.TempDir().
Sidechain/sub-agent JSONL summing and the IDEA-body Pad-invocation-count
fallback are intentionally deferred to v2 (TODOs in session.go).
* fix(cli): session shape — TotalPrompt as context numerator + count parallel tool_use (IDEA-1491)
Codex R1 review findings:
P1 — context_pct numerator was CacheRead, which is a steady-state proxy
that under-counts at turn boundaries when fresh content sits in
cache_creation/input before being folded into the cached prefix. The
correct denominator-of-budget is the full prompt footprint sent this
turn: cache_read + cache_creation + input = TotalPrompt. Markdown
renderer's context-tokens line follows suit; the explicit per-component
breakdown rows keep CacheRead so the components remain visible.
P2 — ToolInvocations was counting assistant-turns-with-any-tool-use, not
tool invocations. A single assistant turn can emit multiple parallel
tool_use blocks in message.content[]; the field name promises a count
of invocations. Drop the early break.
Test fixture normal.jsonl gains a 3-parallel-tool-use final turn; assert
ToolInvocations==4 (up from 2) to pin the new behavior.
* fix(cli): session shape — path-traversal, oversized-line, content-variant, explicit-flag errors (IDEA-1491)
Codex R2 review findings:
P1 — session-ID inputs (--session flag-id branch AND
$CLAUDE_CODE_SESSION_ID env var) are now validated before they become
filename fragments under ~/.claude/projects/<slug>/. Reject path
separators, '..' segments, and anything that doesn't match a UUID-ish
shape (hex+dashes, 8+ chars). New ErrInvalidSessionID wraps a
descriptive message. Without this, `--session ../../../../../tmp/foo`
or a poisoned env var could escape the projects dir on the candidate
os.Stat. End-to-end smoke confirms `pad session shape --session
'../../../etc/passwd'` now errors with "invalid session id: ...
contains a path separator" and exits non-zero.
P2a — Switch the JSONL line reader from bufio.Scanner (8 MiB cap, hard
fail on overflow with "token too long") to bufio.Reader.ReadBytes('\n')
(no cap). encoding/json has no size limit either, so oversized records
— e.g. inline file attachments — parse cleanly. Both ParseSessionJSONL
and tailLineCWD updated for parity.
P2b — jsonlLine.Message.Content was []json.RawMessage at the outer
decode, which made a schema variant where content is a string or
object fail the WHOLE line's decode, losing type/timestamp/version/
usage data. Now Content is a raw json.RawMessage; the tool-use scan
re-decodes it as []json.RawMessage on a best-effort basis and skips
tool-counting when that fails, while preserving the rest of the line.
P3 — `pad session shape --session <id|path>` no longer silently falls
back when the resolver errors. An explicit flag means the caller has a
specific session in mind; a typo or wrong UUID should fail loudly so
automation surfaces the bug instead of emitting `agent: "unknown"`.
The implicit (no-flag) path still falls back for non-Claude-Code
harnesses.
Tests added/extended:
- TestResolveSessionLog_RejectsPathTraversal — flag-id AND env-id
branches, full bad-input matrix.
- TestParseSessionJSONL_OversizedLine — 10 MiB single record.
- TestParseSessionJSONL_NonArrayContent — content-as-string variant
must still contribute timestamp/version/usage.
- TestParseSessionJSONL_ParallelToolUse — tight hermetic check of the
R1 P2 multi-tool-per-turn fix.
- TestBuildSessionShape_ExplicitFlagErrors — verify --session errors
propagate.
- TestBuildSessionShape_ImplicitFallback — verify implicit path
still falls back.
Pad
Project Management for the agent era.
One binary. Local-first. No accounts required. Pad gives you a CLI, a web UI, and an AI agent skill — all backed by SQLite, all running on your machine. Your project data never leaves your laptop.
Quick Start
brew install PerpetualSoftware/tap/pad
cd your-project
pad init # configure, auth, workspace, AI skill — all in one
pad server open # opens the web UI at localhost:7777
pad init is the smart entry point — it auto-detects what's needed, walks you through each step, and is safe to re-run anytime (it skips finished steps and prints a status summary).
Then, in a fresh agent session in your project, say:
use pad to get IDEA-1
Your new workspace ships with a thoughtful first idea — IDEA-1 — that the agent reads and uses to help you get set up around your actual project. It's the fastest way to go from empty workspace to "okay, this is mine."
Why Pad?
Tools like Linear, Jira, and Notion are built for teams on the cloud. Pad is built for developers on their machine — and for the AI agents working alongside them.
| Pad | Linear / Jira | Notion | |
|---|---|---|---|
| Setup | pad init |
Create account, invite team, configure | Create account, pick template |
| AI agents | Native /pad skill for 7+ tools |
Third-party integrations | Third-party integrations |
| Data | Local SQLite, you own it | Their cloud | Their cloud |
| Offline | Full functionality | Read-only cache at best | Limited |
| CLI | First-class | Afterthought | None |
| Price | Free, open source | Per-seat pricing | Per-seat pricing |
Features
For Developers
CLI that doesn't get in your way. Create tasks, search items, check status — without leaving the terminal.
pad item create task "Fix OAuth redirect" --priority high
pad item create idea "Real-time collaboration" --category infrastructure
pad item list tasks --status in-progress
pad item search "authentication"
pad project dashboard # Project dashboard
pad project next # What should I work on?
pad server info # How this client is connected to Pad
Web UI that stays out of your way. A clean, dark-themed interface at localhost:7777 with:
- Board, list, and table views — drag-and-drop between status columns
- Keyboard navigation —
j/kto move,Enterto open,Escto go back,Cmd+Kto search - Rich text editor — Tiptap-based with markdown, formatting toolbar, and auto-save
- Wiki-links — type
[[Title]]to link between items - Real-time updates — agent creates a task in the terminal, it appears in the browser instantly (via SSE)
- Dashboard — collection overview, active work, plan tracking, activity feed
For AI Agents
Your agent becomes a project partner. Install the /pad skill once, and your AI coding tool can read, create, and update project items through natural language.
pad agent install # Auto-detects your tools and installs the skill
Works with Claude Code, Cursor, Windsurf, Codex, GitHub Copilot, Amazon Q, and JetBrains Junie.
Then just talk to your project:
> /pad what should I work on next?
> /pad I finished the OAuth fix
> /pad create a task to add rate limiting
> /pad let's brainstorm about the API redesign
Conventions and playbooks teach agents how your project works:
- Conventions — trigger-based rules like "run tests before marking a task done" or "use conventional commits"
- Playbooks — multi-step workflows like "when implementing a feature: read the spec, create a branch, write tests first, then implement". Playbooks can declare a kebab-case
invocation_slugso users can invoke them directly:/pad ship PLAN-42,/pad release 0.5.0. Freshstartupworkspaces ship a genericshipplaybook out of the box.
pad item create convention "Run tests before completing tasks" \
--field trigger=on-task-complete \
--field scope=all \
--field priority=must
Agents load relevant conventions automatically. All agent actions are attributed in the activity feed, so you always know what the AI changed.
Onboard agents to a new codebase:
pad workspace onboard # Analyzes project structure, saves workspace context, and suggests conventions
Collections & Custom Fields
Pad organizes work into collections — typed containers with structured fields.
Built-in collections:
| Collection | Purpose |
|---|---|
| Tasks | Work items with status, priority, assignee, effort, due date |
| Ideas | Feature ideas with impact and category |
| Plans | Project milestones with progress tracking |
| Docs | Documentation, decisions, reference material |
| Conventions | Project rules that guide agent behavior |
| Playbooks | Multi-step workflows for agents to follow |
Create your own with typed fields — select, text, date, number, url, relation, checkbox:
pad collection create "Bug Reports" \
--fields "severity:select:low,medium,high,critical; browser:text; reproducible:checkbox"
Items get reference numbers automatically (TASK-5, BUG-12) and can be moved between collections with field migration.
Installation
Homebrew (macOS and Linux)
brew install PerpetualSoftware/tap/pad
Build from Source
git clone https://github.com/PerpetualSoftware/pad
cd pad
make build
cp pad ~/.local/bin/ # or /usr/local/bin/
Requires Go 1.26+ and Node.js 22+.
The go install github.com/PerpetualSoftware/pad/cmd/pad@latest path is not supported for the full Pad binary, because the web UI must be built and embedded during the source build.
Docker
docker run -p 127.0.0.1:7777:7777 -v pad-data:/data ghcr.io/perpetualsoftware/pad
This publishes Pad to localhost:7777 on the host machine, which is the recommended default for local use.
Single user, more than one device? Publish to all interfaces so you can reach Pad from your phone, tablet, or another machine on the same LAN, Tailscale network, or home VPN:
docker run -p 7777:7777 -v pad-data:/data ghcr.io/perpetualsoftware/pad
For multi-instance deployments, Pad supports Postgres + Redis via docker-compose.yml — see docs/deployment.md for the full setup.
Binary Download
Pre-built binaries for macOS, Linux, and Windows are available on the releases page.
Getting Started
1. Set up Pad
cd ~/projects/myapp
pad init "My App"
pad init is the smart entry point that handles everything in one command:
- Configures this client's connection (local server, remote, or Docker)
- Auto-starts the local server
- Creates the first admin account on a fresh local install (Docker / remote hosts run
pad auth setupon the server instead) - Logs you in if needed
- Creates or links a workspace for the current directory (writes
.pad.toml) - Installs the
/padskill for any AI tools detected in the project
Run from your project root. Safe to re-run anytime — it skips finished steps and prints a status summary if nothing's needed.
Choose a template with --template, or omit it for an interactive picker grouped by category (Software / People / …):
pad workspace init --list-templates # See the full catalog grouped by category
pad init "My App" --template scrum # Scrum-style with sprints
pad init "My App" --template product # Product management focused
pad init "My Hiring" --template hiring # Company-side: requisitions, candidates, interview loops, feedback
pad init "Job Search" --template interviewing # Candidate-side: applications, interviews, companies, contacts
Pad ships templates for software (startup / scrum / product), people workflows (hiring, interviewing), and has reserved categories for research, content, operations, and personal use so the same project-management primitives fit well beyond code projects.
2. Start working
# From the CLI
pad item create task "Set up CI pipeline" --priority high
pad item create idea "Add WebSocket support" --category infrastructure
pad project dashboard
# From the web UI
pad server open # Opens localhost:7777 in your browser
# From your AI agent
# Just use /pad in Claude Code, Cursor, etc.
3. Teach your agents the rules
pad workspace onboard # Auto-analyze project, save workspace context, and suggest conventions
# Or browse the convention library
pad library list --type conventions # Pre-built conventions you can adopt
pad library list --type playbooks # Pre-built multi-step workflows
4. Optional — connect a desktop AI app via MCP
Pad ships an MCP (Model Context Protocol) server so Claude Desktop, Cursor, or Windsurf can manage items, plans, ideas, and dependencies as native tools, read workspace state by URL, and load multi-step workflows as prompts.
pad mcp install claude-desktop # or: cursor, windsurf, --all
# Restart the client; pad shows up as the "pad" MCP server.
Tool catalog (v0.4) — eight resource × action tools plus pad_set_workspace (nine total), no flat verb explosion:
| Tool | Actions |
|---|---|
pad_item |
create, update, delete, get, list, move, link, unlink, deps, star, unstar, starred, comment, list-comments, bulk-update, note, decide |
pad_workspace |
list, members, invite, storage, audit-log |
pad_collection |
list, create |
pad_project |
dashboard, next, standup, changelog |
pad_role |
list, create, delete |
pad_search |
query |
pad_playbook |
list, get, run |
pad_meta |
server-info, version, tool-surface, bootstrap |
pad_set_workspace |
session-default workspace pinning (response embeds the bootstrap blob) |
Plus resources at pad://workspaces, pad://workspace/{ws}/dashboard,
pad://workspace/{ws}/items, pad://workspace/{ws}/items/{ref},
pad://workspace/{ws}/collections, pad://workspace/{ws}/bootstrap,
and pad://_meta/version.
Stability contract — two version constants, both advertised in the
initialize handshake under capabilities.experimental.padCmdhelp and
capabilities.experimental.padToolSurface (and queryable at
pad://_meta/version):
cmdhelp_version: "0.1"— CLI help-tree contract (used at dispatch time)tool_surface_version: "0.4"— MCP tool catalog contract (PLAN-1410 trimmed the bootstrap-response shape by ~40%; seeinternal/mcp/version.gofor the full v0.4 changelog)
External agents pin against these so a future rename doesn't break them
silently. Errors come back as structured envelopes ({error: {code, message, hint, available_workspaces, ...}}) with a closed eight-code
taxonomy.

Authentication
Pad runs without authentication by default for frictionless local use. For local installs, pad init creates the first admin account inline. The lower-level commands are useful when you're hosting a Pad server (Docker / remote) and need to set up auth on the server host directly:
pad auth setup # Initialize the first admin account (server host, non-local mode)
pad auth login # Sign in
pad auth whoami # Show current user
pad auth logout # Sign out
Once a user exists, all API requests and web UI access require authentication. Credentials are stored in ~/.pad/credentials.json. Multiple users can be invited to workspaces with role-based access control (owner, editor, viewer).
pad workspace members # List workspace members
pad workspace invite user@example.com
pad workspace join <code>
