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 | $0.00016 | $0.00594 |
| Opus 5 | $0.00008 | $0.00297 |
| Sonnet 5 | $0.00003 | $0.00119 |
| Haiku 4.5 | $0.00002 | $0.00059 |
Grade A, and why
btca-local 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 yesterday.
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.
This is a copy
100% identical to btca-local — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.
BTCA Local
BTCA Local, aka "The Better Context App Local" is a simple app defined as a skill file. The purpose of this app is to search git repos cloned onto this machine.
the BTCA Search Workflow
<end_goal> a clear, concise answer to the question with code examples </end_goal>
Startup Cases:
This skill can be invoked in a couple different ways, and your behavior should reflect that:
user invoked without extra context/question
this is the "app startup" state, almost as if a terminal app was booted up.
Your job is to search the working directory ~/.btca/agent/sandbox at the top level, just to get a list of all the repos that have been previously cloned
Then you should simply output the following markdown (filling in the existing repos):
# BTCA Local
_use your coding agent to search any git repo locally_
Previously searched:
- repo 1
- ...
Give me a question and the link to a git repo to get started!
(we can also clean out or pre-load some resources to this list...)
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.

btca-local is a skill published in the GitHub repository davis7dotsh/better-context (1,157 stars, last pushed 4mo ago), licensed MIT. It adds 16 tokens to every session and 594 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to btca-local, differing in 0 lines, and is treated as a copy.
