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 | $0.00042 | $0.00622 |
| Opus 5 | $0.00021 | $0.00311 |
| Sonnet 5 | $0.00008 | $0.00124 |
| Haiku 4.5 | $0.00004 | $0.00062 |
Grade A, and why
find-replace 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 4d 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.
What it actually says
Find Replace
Modern find-and-replace using sd.
sd Basics
# Replace in file (in-place)
sd 'oldText' 'newText' file.txt
# Replace in multiple files
sd 'oldText' 'newText' *.js
# Preview without changing (pipe)
cat file.txt | sd 'old' 'new'
sd vs sed
| sed | sd |
|---|---|
sed 's/old/new/g' |
sd 'old' 'new' |
sed -i 's/old/new/g' |
sd 'old' 'new' file |
sed 's#path/to#new/path#g' |
sd 'path/to' 'new/path' |
Key difference: sd is global by default, no delimiter issues.
Common Patterns
# Variable/function rename
sd 'oldName' 'newName' src/**/*.ts
# Word boundaries (avoid partial matches)
sd '\boldName\b' 'newName' src/**/*.ts
# Import path update
sd "from '../utils'" "from '@/utils'" src/**/*.ts
# Capture groups
sd 'console\.log\((.*)\)' 'logger.info($1)' src/**/*.js
Safe Batch Workflow
# 1. List affected files
rg -l 'oldPattern' src/
# 2. Preview replacements
rg 'oldPattern' -r 'newPattern' src/
# 3. Apply
sd 'oldPattern' 'newPattern' $(rg -l 'oldPattern' src/)
# 4. Verify
rg 'oldPattern' src/ # Should return nothing
git diff # Review changes

Tips
| Tip | Reason |
|---|---|
Always preview with rg -r first |
Avoid mistakes |
| Use git before bulk changes | Easy rollback |
Use \b for word boundaries |
Avoid partial matches |
| Quote patterns | Prevent shell interpretation |

What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 4d ago First seen · 94 lines · 42 tokens per session scan A 3161f3c78fa1
find-replace is a skill published in the GitHub repository 0xDarkMatter/claude-mods (32 stars, last pushed 12d ago), licensed MIT. It adds 42 tokens to every session and 622 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

Use when creating or maintaining OpenCLI site sitemaps: agent-facing navigation, page-state, action, workflow, API-reference, pitfall, and fallback knowledge for a website. Use after browser exploration discovers durable site context, when a sitemap is stale, or when promoting local site knowledge into the repo.
