better-context, also called btca, helps coding agents answer questions about project libraries and frameworks by searching their actual source code instead of relying only on documentation. It is for developers who need current technical context during coding, and the catalogue entries package its agent skill, rule, command, and instruction.
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.

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 | $0.00016 | $0.00594 |
| Opus 5.5 | $0.00006 | $0.00238 |
| Sonnet 5.5 | $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 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.
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 (1,156 stars, last pushed 6mo ago), licensed MIT. It adds 16 tokens to every session and 594 once invoked, about $0.0001 per session on Opus 5.5. 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.
