Heaven's Feel

A Claude Code mod that gives every agent a character from Fate/stay night: Heaven's Feel.

• Sakura's room. A pane where an animated pixel Sakura shows what the session is doing: thinking, reading, editing, running commands, summoning, resting. Past 75% context she turns into Dark Sakura.
• Servants for subagents. Each subagent is summoned as a Servant who suits the job. Explore is Rider, Plan is Caster, general-purpose is Saber, reviewers are Archer, debuggers are True Assassin. Their cards appear in Sakura's room, and pressing one opens that Servant's own transcript.
• A face on every message. Main-session replies wear a Master's face (Sakura, Shirou, Rin, Illya or Kirei, chosen per message). A subagent's replies wear its Servant's face.
• A band above the prompt with Sakura's portrait, what she is doing, and a figure for each working Servant.
• The spinner gets an in-character verb.

It draws pixel art on the terminal and animated SVG in the Claude desktop app, matching the app's light or dark theme.

You need a Claude Code version with mods (function hooks).

Use

/hf opens Sakura's room. It also takes these arguments: on, off, cast (the full roster), dark, say, sleep, bond.

Settings, under the plugin's options:

| Option | Default | What it does | | :- | :- | :- | | Open pane on start | on | Opens Sakura's room when a session starts (wide terminals only) | | Band above prompt | auto | auto, always or never | | Spinner takeover | word | off or word | | Dark Sakura threshold | 75 | Context percent where Sakura turns dark | | Sleep after (minutes) | 5 | Idle time before she falls asleep | | Timezone | Asia/Jerusalem | For her greetings, which keep Shabbat |

Turn it on and off

| To turn off | How | | :- | :- | | The whole mod | claude plugin disable heavens-feel@heavens-feel, or the Installed tab of /plugin; claude plugin enable heavens-feel@heavens-feel brings it back. A running session picks it up with /reload-plugins | | Sakura's room | /hf off closes it and /hf on opens it; it reopens on its own at the next session unless you closed it last, or set Open pane on start off | | The band above the prompt | Set Band above prompt to never | | The spinner word | Set Spinner takeover to off |

Set options with claude plugin configure heavens-feel@heavens-feel, or from /plugin inside a session. To remove it entirely: claude plugin uninstall heavens-feel@heavens-feel.

What it can reach

A mod runs inside Claude Code with your permissions. This one reads session events, transcripts and subagent messages to draw them, keeps a few values in its plugin store (a bond counter, whether the pane was open, a Dark Sakura override), and makes no network requests. Run claude plugin validate on the folder to see every hook and call it makes.

The Sakura portraits were drawn as pixel art and refined with image generation; tools/ holds the Python pipeline that turns the PNGs in art/ into hooks/sprites.generated.ts. DESIGN.md is the original design.
