Yorishiro: macOS terminal that gives coding agents a 3D presence and visual reactions

TL;DR in plain English

• Yorishiro is an open-source terminal project; the repository is at https://github.com/sktkkoo/Yorishiro and the repository description reads: "a terminal that gives AI a body and a living space." See the repo page: https://github.com/sktkkoo/Yorishiro.
• Goal: run the demo UI referenced from the repository and validate a simple local watcher that visually signals a build failure so you can spot errors at a glance. Confirm the exact demo and pack-loading instructions in the repo README: https://github.com/sktkkoo/Yorishiro.
• Why try this: a glanceable visual cue can reduce time spent scanning logs; evaluate locally before changing CI. For authoritative details, consult the project README and examples at https://github.com/sktkkoo/Yorishiro.

What you will build and why it helps

Plain summary

You will run a local instance of the Yorishiro demo UI referenced in the repository and experiment with a minimal watcher (a local, reversible configuration or "pack") that reacts when your local build prints a specific failure line. The repository page is the canonical starting point: https://github.com/sktkkoo/Yorishiro.

Why this pattern helps

• Glance detection: a visible change (color flash, scene pose) can alert you in <1 s more often than manual log scanning.
• Low friction: prototype locally without CI changes; follow the repo README at https://github.com/sktkkoo/Yorishiro to find demo notes.
• Reusable: the watcher → visual action pattern can be applied to test failures, regressions, or other textual signals that appear during local workflows.

Where to check in the repo

• Top-level README and any example folders are the authoritative sources for demo start commands and pack formats: https://github.com/sktkkoo/Yorishiro.

Decision frame (quick comparison)

| Option | Effort | Reversibility | When to use | |---|---:|---:|---| | Run only demo UI | Low | Immediate undo (stop app) | Verify UI and platform support quickly (5–30 min) | | Add local watcher pack | Medium | High (local config only) | Prototype glanceable alerts for one developer or small team | | Integrate into CI | High | Medium | Larger teams, after a 2–4 week pilot |

(See the project page for confirmed examples: https://github.com/sktkkoo/Yorishiro.)

Before you start (time, cost, prerequisites)

Read the repo README first: https://github.com/sktkkoo/Yorishiro. The README is the authoritative place to confirm supported OS, runtimes, and demo instructions.

Minimal prerequisites (verify in repo):

• A desktop or laptop for local UI work. Check platform notes in the README: https://github.com/sktkkoo/Yorishiro.
• Git installed and network access to clone the repository.
• Basic comfort with shell commands and editing small text files.

Estimated time (illustrative—validate in repo):

• Clone and read README: 5–20 minutes.
• Install and run demo: 15–90 minutes depending on platform toolchain.
• Prototype a watcher and test: 30–120 minutes.

Pre-run checklist

• [ ] Clone the repository and open the top-level README: https://github.com/sktkkoo/Yorishiro
• [ ] Confirm platform/toolchain notes in the README
• [ ] Backup any terminal settings you will modify

Where to look in the repo

• README and example/ or packs/ folders (if present) for demo scenes and packs: https://github.com/sktkkoo/Yorishiro

Step-by-step setup and implementation

These steps are conservative: follow the README for exact commands and filenames at https://github.com/sktkkoo/Yorishiro.

1. Clone the repository (definitive step)

git clone https://github.com/sktkkoo/Yorishiro.git
cd Yorishiro

2. Read the top-level README and any example folders mentioned there. The README on the repo page is the source of truth: https://github.com/sktkkoo/Yorishiro.

3. Start the demo UI per the README. (Do not assume script names—confirm them in the repo.)

4. Locate example packs or demo scene files mentioned in the README or example folders.

5. Prototype a minimal watcher locally (keep it reversible and local-only). Store such files in a clearly named folder like ./local-packs/ so you can remove them quickly. Validate pack-loading actions per the README: https://github.com/sktkkoo/Yorishiro.

6. Test with a short script that emits the chosen failure line, and verify the visual reaction in the demo UI.

Helpful debug pattern

• If something fails to start, re-open the README and any linked install notes and issue tracker on the repo page: https://github.com/sktkkoo/Yorishiro. Native modules or platform toolchains can require extra steps; the README is authoritative.

Quick command examples (check README for exact scripts)

# Example: rebuild and run — confirm script names in repo
# (these are illustrative; validate in the README or package.json)
# npm run build && npm run start

Common problems and quick fixes

Always check the repository README and issues at https://github.com/sktkkoo/Yorishiro first; the project page is the authoritative reference.

Common problems

• App won't start: re-run install steps listed in README; ensure platform toolchains are installed.
• Demo UI visible but watcher doesn't trigger: confirm pack file placement and match patterns (case, whitespace). See example folders or README: https://github.com/sktkkoo/Yorishiro.
• High CPU or rendering lag: check for a low-detail or headless mode documented in the repo; otherwise reduce scene complexity or disable effects.

Quick fixes

• Increase watcher logging verbosity (local-only) to confirm input lines reach the watcher.
• Test match patterns with an exact script that prints the target line.

Useful commands (examples)

# Tail a log file if the project logs to files (replace path per README)
tail -n 200 -f logs/yorishiro.log

# Rebuild and restart (illustrative — verify exact scripts in repo)
npm run build && npm run start

First use case for a small team

Target audience: an individual developer or a small team evaluating glanceable local alerts. Start with a single-user prototype and then scale to a 3–5 person canary group.

Minimal one-afternoon prototype

1. Clone the repository and confirm the demo UI runs per the README: https://github.com/sktkkoo/Yorishiro.
2. Place a single local watcher file in ./local-packs/ (or the equivalent folder the README documents) and configure it to match an exact failure string from your build script. Keep the watcher enabled via a simple toggle so it is easy to disable.
3. Run a short script that emits that failure string to validate the visual reaction.

Team quick-start checklist

• [ ] Clone the repo and run the demo UI (see README: https://github.com/sktkkoo/Yorishiro)
• [ ] Implement a single local watcher that matches your build failure line
• [ ] Test with a short failing-build script in a dev environment
• [ ] Pilot with 3–5 developers before wider rollout

Measure and iterate

• Track time-to-acknowledge (TTA) for failures and false-positive counts over a 2–4 week pilot.
• If false positives are high, tighten match patterns or add contextual checks.

Technical notes (optional)

• The repository identifies itself with the phrase: "a terminal that gives AI a body and a living space." See the project page: https://github.com/sktkkoo/Yorishiro.
• Inspect example packs, demo scenes, and adapter interfaces in the source tree before coding against them; the README and example folders are the canonical sources: https://github.com/sktkkoo/Yorishiro.
• If you connect external services or LLMs, keep keys out of source files and use environment variables or a secret manager; check adapter examples in the repo for recommended patterns: https://github.com/sktkkoo/Yorishiro.

Decision table: local vs small-team vs production

| Phase | Scope | Key checks | When to proceed | |---|---|---|---| | Local prototype | 1 developer | Demo UI runs, watcher triggers locally | Confirm within 1 day | | Small-team pilot | 3–5 developers | Low false positives, <50% extra interrupts | Run 2–4 weeks | | Production rollout | >10 developers | Governance, PR reviews, monitoring | Proceed after pilot metrics meet thresholds |

What to do next (production checklist)

Follow the repository README and examples at https://github.com/sktkkoo/Yorishiro to validate all items below.

Assumptions / Hypotheses

The following items are assumptions or hypotheses you must validate in the repository source and README at https://github.com/sktkkoo/Yorishiro:

• Repository identity: the repo exists at https://github.com/sktkkoo/Yorishiro and uses the description string quoted above (confirmed on the project page).
• The repository contains demo scenes and example packs or a pack-loading mechanism (hypothesis to confirm by inspecting the README and example folders).
• CLI/script names and filenames are not assumed here; example scripts used earlier are illustrative and must be validated against the repo's README and package.json.

Example illustrative watcher config (hypothesis — validate exact schema in repo):

{
  "name": "local-build-reflex",
  "watch": { "pattern": "BUILD FAILED", "action": "scene.flashRed" },
  "persona": { "name": "BuilderBot" }
}

Example numeric targets (starting points to validate):

• Setup time estimate: 5–120 minutes depending on environment.
• Prototype test duration: 30–120 minutes.
• Pilot group size: 3–5 users initially.
• Pilot duration: 2–4 weeks (approx. 14–28 days).
• CPU idle target for dev laptops: <30% (while app runs in background).
• Memory target: <1.5 GB RAM for background mode.
• Visual response latency target: <500 ms for scene reaction.
• LLM token budgets (if used): 2,048 or 8,000 tokens as example caps.

Methodology note: this document references the repository name and description from the project page at https://github.com/sktkkoo/Yorishiro and uses illustrative examples that must be validated in the repo README and source tree.

Risks / Mitigations

• Risk: accidental commit of secrets. Mitigation: enforce pre-commit hooks and use environment variables or secret stores; require PR reviews for shared packs.
• Risk: excessive CPU/GPU usage on developer machines. Mitigation: provide low-detail or headless fallbacks and expose toggles to disable rendering.
• Risk: false positives from broad match patterns. Mitigation: use anchored, case-sensitive patterns and pilot with a small group (3–5 users).
• Risk: team confusion about signals. Mitigation: document a short legend for colors/animations and limit the visual vocabulary to <5 distinct signals.

Next steps

1. Visit the repository page and validate the README and demo files: https://github.com/sktkkoo/Yorishiro.
2. Clone the repo and confirm the demo UI starts on your platform (use the README for exact start/build commands).
3. Implement one local watcher pack and test with a short failing-build script in a dev environment.
4. Run a 3–5 user canary for 2–4 weeks and collect metrics: time-to-acknowledge and false-positive counts.
5. If pilot metrics meet targets, add governance: require PR reviews for shared packs and maintain an approved pack registry before wider adoption.
