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.

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 | $0.00053 | $0.00725 |
| Opus 5 | $0.00026 | $0.00362 |
| Sonnet 5 | $0.00011 | $0.00145 |
| Haiku 4.5 | $0.00005 | $0.00072 |
Grade A, and why
kconfig-tweak scanned grade A with 0 findings 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 11d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 100 lines — stays where its author put it; the contents beside it link to each section on GitHub.
kconfig-tweak
Command-line tool for modifying .config files without launching interactive menuconfig.
Quick Reference
# Enable/disable options
kconfig-tweak --enable DEBUG_INFO
kconfig-tweak --disable MODULES
kconfig-tweak -e SMP -d PREEMPT # Multiple in one command
# Set values
kconfig-tweak --set-val LOG_BUF_SHIFT 17
kconfig-tweak --set-str LOCALVERSION "-custom"
# Query state
kconfig-tweak --state DEBUG_INFO # Returns: y, n, m, or undef
# Specify config file
kconfig-tweak --file boards/myboard/.config --enable USB
# Module support
kconfig-tweak --module DRM # Set to m (module)
Commands
| Command | Short | Description |
|---|---|---|
--enable OPTION |
-e |
Set option to y |
--disable OPTION |
-d |
Set option to n |
--module OPTION |
-m |
Set option to m (module) |
--set-val OPTION VALUE |
- | Set integer/hex value |
--set-str OPTION STRING |
- | Set string value (quoted) |
--undefine OPTION |
-u |
Remove option definition |
--state OPTION |
-s |
Query current state |
Position Control
Insert options after a specific option (useful for maintaining config order):
kconfig-tweak --enable-after USB USB_STORAGE # -E
kconfig-tweak --disable-after NET BRIDGE # -D
kconfig-tweak --module-after DRM DRM_I915 # -M
Options
| Option | Description |
|---|---|
--file FILE |
Target config file (default: .config) |
--keep-case / -k |
Preserve symbol case (default: auto-uppercase) |
Environment Variables
CONFIG_- Symbol prefix (default: "CONFIG_")
Common Patterns
Batch Configuration
# Enable multiple debug options
kconfig-tweak -e DEBUG_INFO -e DEBUG_FS -e KALLSYMS
# Configure network stack
kconfig-tweak --file .config \
-e NET -e INET -e IPV6 \
--set-val TCP_CONG_CUBIC y
CI/CD Integration
# Start from defconfig, then customize
make defconfig
kconfig-tweak -e DEBUG_INFO -d MODULES
make olddefconfig # Resolve dependencies
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.

kconfig-tweak is a skill published in the GitHub repository open-vela/.claude (5 stars, last pushed yesterday), licensed Apache-2.0. It adds 53 tokens to every session and 725 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
