Changelog

0.15.0 - 2026-05-15

Major Claude Code parity release. 21 CLI flags (up from 7), 6 new subcommands, Skills system, permission modes, worktrees, background agents.

New flags:

• --system-prompt, --system-prompt-file, --append-system-prompt, --append-system-prompt-file - customize the system prompt at runtime. See System prompt customization.
• --effort low|medium|high|xhigh|max - control how much compute IsonForge spends per turn. See Effort levels.
• --max-turns, --max-budget-usd, --output-format text|json|stream-json, --json-schema - print-mode bounded execution and structured output. See Print mode.
• --add-dir <path> - additional working directories, repeatable.
• --permission-mode default|acceptEdits|plan|auto|bypassPermissions - five permission modes, Shift+Tab cycle in the REPL. See Permission modes.
• --settings <path-or-json>, --setting-sources <list> - settings precedence (user / project / local / runtime). See Settings.
• -w / --worktree [name], --from-pr <pr> - isolated git worktrees, PR-driven workflow. See Worktrees.
• --bg - run prompts as detached background agents. See Background agents.
• --dangerously-skip-permissions - alias for --yolo (Claude-Code muscle-memory).
• --resume - interactive session picker at startup.

New subcommands:

• isonforge agents - list background agents.
• isonforge logs <id> - tail an agent's stdout log.
• isonforge attach <id> - follow an agent's output live.
• isonforge stop <id> - terminate an agent.
• isonforge rm <id> - remove a stopped agent from the list.
• isonforge respawn <id> - restart a stopped agent with its original prompt.

New slash commands:

• /effort [low|medium|high|xhigh|max] - change effort mid-session.
• /skills - list installed Skills.

Skills system:

• Drop SKILL.md into ~/.isonforge/skills/<name>/ or <cwd>/.isonforge/skills/<name>/ and /your-skill becomes a command.
• YAML frontmatter, $ARGUMENTS / $0..$9 substitution, dynamic shell injection via `!``cmd```.
• Compatible with Claude Code's .claude/skills/ and .claude/commands/.

Gateway changes:

• Default thinking ON (was OFF). Reasoning-pane UI ships in the CLI - the env var is now finally aligned with the CLI capability.
• System prompt adds deep-exploration pressure (read callers + callees + tests, hypothesis before edit) and sub-agent delegation push (task_explore for unfamiliar code).
• permission_mode=plan server-side filter strips mutating tools.
• effort per-request maps to backend sampling + reasoning.

Installer fixes:

• install-forge.sh: dropped --strip-components=1 (tarball has no wrapper dir, was silently skipping package.json).
• install-forge.sh: replaced npm install --production 2>&1 | tail -1 (hid real errors) with proper --omit=dev + visible error path.
• install-forge.ps1: switched MSI download + admin-required msiexec /qn to winget install OpenJS.NodeJS.LTS (clean UAC, auto PATH refresh).
• install-forge.ps1: use npm.cmd to bypass PowerShell ExecutionPolicy Restricted.

UI palette:

• CLI repalette to single Anthropic-copper accent (#D97757). Replaces previous purple + cyan + amber. Single accent across Welcome banner, spinner, prompt, message bullet, cursor, markdown render.

0.10.x - 2026-05-09

• IsonForge CLI v0.9.0 / v0.10.0 - PRME 26.1 backend swap. 25 slash commands. /upgrade self-restart, /web, /cost, sub-agent split into task_explore + task_research, ask_user, /loop.
