An interactive setup tool for configuring ContextGuard, a project-local collection of token-saving and context-management settings for Claude Code.

Use it to check setup health, preview configuration changes, enable local protections for bulky reads and command output, add status information, and configure related defaults.

It lets you inspect available safeguards and apply selected settings without manually editing configuration files or memorizing commands.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add ictechgy/context-guard --skill setup

Clone the repo

git clone --depth 1 https://github.com/ictechgy/context-guard

Made for: Claude Code.

Or install context-guard, the plugin that ships this one along with the rest of its 3 skills.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00035	$0.00551
Opus 5.5	$0.00014	$0.00220
Sonnet 5.5	$0.00007	$0.00110
Haiku 4.5	$0.00003	$0.00055

Security

Grade B, and why

setup scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

What it actually says

ContextGuard Setup

Goal: help the user configure this plugin without memorizing helper commands.

Default flow:

Run a read-only health check and plan first:

context-guard-setup --verify
context-guard-setup --plan

Explain the three profiles briefly (--profile):
- minimal: deny bulky/sensitive reads + large Read guard only,
- recommended (default): adds the Bash trim/escrow + sanitizer hook and missing model/effort defaults (the statusline is deprecated and no longer part of this profile),
- max: adds the failed-attempt nudge for repeated Bash failures (off by default until false-positive data exists). Individual --no-* flags remove one item from a profile.
If the user wants the recommended project-local setup, run:

context-guard-setup --yes

For the fullest set: context-guard-setup --profile max --yes.

Treat the post-apply context-guard-diet scan summary emitted by setup as the default remaining-gap check; run context-guard-diet scan . separately only when the user wants the full report.
For automation that must skip the post-apply scan summary, run context-guard-setup --no-diet-scan --yes.
If they want extra token reduction beyond setup, prefer local artifact escrow, symbol reads, and semantic digests rather than external model offload.
If a hook misfires, turn it off for this session instead of re-running setup: context-guard-hooks off read|bash|nudge|all [--for 2h], then context-guard-hooks status / on.

Safety:

Do not modify global ~/.claude/settings.json.
Prefer project-local .claude/settings.json.
context-guard-setup --verify is a local read-only health check and never applies settings.
Setup's post-apply scan is local, read-only, and prints a summary only; it does not mutate settings.
Setup should use packaged/check-out helper paths by default; only pass --allow-path-helper-fallback when the user explicitly trusts a PATH-installed ContextGuard helper set.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

setup is a skill published in the GitHub repository ictechgy/context-guard (3 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 35 tokens to every session and 551 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

The world feels messy. Stale tasks, orphan folders, v2 remnants, unsaved sessions — entropy is accumulating and needs to be addressed before it compounds. Scans across all walnuts, then surfaces issues one at a time.

alive:world

The human doesn't know what to work on, or wants to see everything at once. They need the big picture — what's active, what's stale, what needs attention. Renders a live world view grouped by ALIVE domain, then routes to open, tidy, find, history, or map.

The human wants to adjust how the system behaves — not what it contains, but how it feels. Voice, rhythm, preferences, walnut-level config, full permissions toggleable, named squirrel config, action logging toggle. The system adapting to them.
