I would recommend you to try using FIM/line completion rather than the agent approach. Using FIM it makes me (feel) productive while still being in control. Oftentimes when writing code for production, documentation etc. the agent approach feels like a wash to me - sometimes it saves time, sometimes it wastes time. With FIM the gain/quality is more consistent.

strncpy was originally used to write into fixed length buffers[1]. This becomes obvious when considering the padding behavior, as described in the C standard[2]: "If the array pointed to by s2 is a string that is shorter than n characters, null characters are appended to the copy in the array pointed to by s1, until n characters in all have been written."

strlcpy, often touted as a replacement, does not elicit the padding behavior but has another flaw: It is supposed to return the length of the string it tried to create, for example, so the user can call realloc without calling strlen again.[3] However, this final "strlen-tail" in strlcpy isn't bounded by the size parameter which describes dest, not src.

While strscpy is a marked improvement, there is still something to be careful about: It can read past the end of the src-buffer, when sizeof src < sizeof dest and src is not nul-terminated.[4] (Set the count argument to something like min(sizeof dest, sizeof src) to avoid that).
