age-inspect on identity and recipient files fails to parse

[julian94]

While I understand in retrospect that age-inspect is only meant to inspect age-encrypted files, it would be nice if it could either give a more helpful error message or ideally some useful information.

Output from trying to parse recipient and identity files.

$ age-inspect age-key.txt 
age-inspect: error: inspection failed: failed to read header: parsing age header: unexpected intro: "# created: 2026-01-13T16:11:18+01:00\n"
age-inspect: report unexpected or unhelpful errors at https://filippo.io/age/report

$ age-inspect age-recipient.txt 
age-inspect: error: inspection failed: failed to read header: parsing age header: unexpected intro: "age1feapjcdlwldcdez70csqtqyuwa033x72jypuqtv797gn3grjue2qs0ygzr\n"

Example of more useful information

    }
  ]
}
