Use when editing Nerd Font icons, Private Use Area glyphs, terminal prompts, tmux status bars, or CLI UI symbols.
Install with Codex or Claude Copy this prompt, paste it into Codex, Claude, or another assistant, and let it review the skill page and install it for you.
Based on SOC occupation classification
Use when improving Codex steering, token/context cost, hooks, skills, plugins, MCPs, or dotty-managed config.
Generic Godspeed list and label discovery, inbox triage, and API-backed task organization for a mirrored GTD setup with work and personal folders. Use when Codex needs to inspect Godspeed lists, summarize inbox or active tasks, or apply explicit task updates through the Godspeed API without tracking personal taxonomy in the repo.
Use when TypeScript or TSX work needs guidance on API shape, function signatures, exported contracts, strict typing, lint-safe escape hatches, or lightweight off-the-shelf library choices for JS/TS tools.
Use when diagnosing terminal or TUI rendering problems: ANSI color/theme mismatches, truecolor vs xterm-256 vs terminal-palette behavior, Markdown/code renderer differences, pager output, tmux or fzf preview wrapping, or CLI UI screenshots that look different from expected.
Use when writing a new README from scratch, creating, auditing, or updating README/repo landing pages, setup docs, CLI docs, contributor notes, AGENTS/repo steering docs, or docs drift checks.
Use when React or frontend work needs guidance on cleanup and simplification, component boundaries, hooks, context, rendering, testing, or modern React defaults.

Use this skill when a file contains or generates Nerd Font icons. Preserve exact bytes; do not trust how glyphs look in the editor.
Nerd Fonts patch programming fonts with icons from sets such as Font Awesome, Devicons, and Octicons. Many live in Unicode Private Use Area ranges:
U+E000 through U+F8FFU+F0000 through U+FFFFFThey may render as icons, blanks, or replacement boxes depending on the tool. Visual inspection does not prove they survived an edit.
perl -0pi, sed, or a proven formatter.Use codepoints or UTF-8 byte escapes:
# Print a Font Awesome check glyph by codepoint.
printf '\U0000F00C'
# Convert a codepoint to UTF-8 hex bytes.
printf '\U0000F00C' | xxd -p
# Convert a codepoint to printf-style byte escapes.
codepoint="F00C"
printf "\\U0000${codepoint}" | xxd -p | sed 's/\(..\)/\\x\1/g'
For macOS sed, use -i '':
sed -i '' "s/ICON_CHECK/$(printf '\xef\x80\x8c')/" file.sh
For GNU sed, use -i:
sed -i "s/ICON_CHECK/$(printf '\xef\x80\x8c')/" file.sh
Hex dump relevant lines before and after the edit:
sed -n '29,31p' file.sh | xxd
For a single expected codepoint:
printf '\U0000F00C' | xxd -p
If the expected bytes are absent after the edit, restore the line from git or reinsert the glyph from the codepoint/byte escape.
