1. Below is the context usage show in progress bar
#!/bin/bash
# Read all of stdin into a variable
input=$(cat)

# Extract fields with jq, "// 0" provides fallback for null
MODEL=$(echo "$input" | jq -r '.model.display_name')
PCT=$(echo "$input" | jq -r '.context_window.used_percentage // 0' | cut -d. -f1)

# Build progress bar: printf -v creates a run of spaces, then
# ${var// /▓} replaces each space with a block character
BAR_WIDTH=10
FILLED=$((PCT * BAR_WIDTH / 100))
EMPTY=$((BAR_WIDTH - FILLED))
BAR=""
[ "$FILLED" -gt 0 ] && printf -v FILL "%${FILLED}s" && BAR="${FILL// /▓}"
[ "$EMPTY" -gt 0 ] && printf -v PAD "%${EMPTY}s" && BAR="${BAR}${PAD// /░}"

echo "[$MODEL] $BAR $PCT%"
  1. CLAUDE.md
These rules apply to every task in this project unless explicitly overridden.
Bias: caution over speed on non-trivial work. Use judgment on trivial tasks.

## Rule 1 — Think Before Coding
State assumptions explicitly. If uncertain, ask rather than guess.
Present multiple interpretations when ambiguity exists.
Push back when a simpler approach exists.
Stop when confused. Name what's unclear.

## Rule 2 — Simplicity First
Minimum code that solves the problem. Nothing speculative.
No features beyond what was asked. No abstractions for single-use code.
Test: would a senior engineer say this is overcomplicated? If yes, simplify.

## Rule 3 — Surgical Changes
Touch only what you must. Clean up only your own mess.
Don't "improve" adjacent code, comments, or formatting.
Don't refactor what isn't broken. Match existing style.

## Rule 4 — Goal-Driven Execution
Define success criteria. Loop until verified.
Don't follow steps. Define success and iterate.
Strong success criteria let you loop independently.

## Rule 5 — Use the model only for judgment calls
Use me for: classification, drafting, summarization, extraction.
Do NOT use me for: routing, retries, deterministic transforms.
If code can answer, code answers.

## Rule 6 — Token budgets are not advisory
Per-task: 4,000 tokens. Per-session: 30,000 tokens.
If approaching budget, summarize and start fresh.
Surface the breach. Do not silently overrun.

## Rule 7 — Surface conflicts, don't average them
If two patterns contradict, pick one (more recent / more tested).
Explain why. Flag the other for cleanup.
Don't blend conflicting patterns.

## Rule 8 — Read before you write
Before adding code, read exports, immediate callers, shared utilities.
"Looks orthogonal" is dangerous. If unsure why code is structured a way, ask.

## Rule 9 — Tests verify intent, not just behavior
Tests must encode WHY behavior matters, not just WHAT it does.
A test that can't fail when business logic changes is wrong.

## Rule 10 — Checkpoint after every significant step
Summarize what was done, what's verified, what's left.
Don't continue from a state you can't describe back.
If you lose track, stop and restate.

## Rule 11 — Match the codebase's conventions, even if you disagree
Conformance > taste inside the codebase.
If you genuinely think a convention is harmful, surface it. Don't fork silently.

## Rule 12 — Fail loud
"Completed" is wrong if anything was skipped silently.
"Tests pass" is wrong if any were skipped.
Default to surfacing uncertainty, not hiding it.
  1. Possible to use opusplan
# this will use opus in plan, and sonnet for execution
/model opusplan
  1. Ask claude to add debug logs as much as possible while generating code so it will take less to fix if not working and less tracing iteration.
  2. LLM takes to much time on refactoring, First make a plan then build.
  3. Create your own RULE.md in which all rules are defined.
