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 5.1 | $0.00035 | $0.00730 |
| Opus 5 | $0.00017 | $0.00365 |
| Sonnet 5 | $0.00007 | $0.00146 |
| Haiku 4.5 | $0.00003 | $0.00073 |
Grade A, and why
context-budget-analyzer 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 8d 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.
How it starts
The opening of the file, as written. The whole thing — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Context Budget Analyzer
Reads
CLAUDE.md.claude/skills/.claude/agents/.claude/rules/context/reference/
Step 1: Scan Workspace Components
Use Glob to find all files in:
.claude/skills/**/*.md.claude/agents/**/*.md.claude/rules/*.mdcontext/*.mdreference/*.mdCLAUDE.md
Read each file. Estimate token count using the approximation: 1 token per 4 characters.
Step 2: Classify Loading Behavior
| Category | Loaded When | Impact |
|---|---|---|
| CLAUDE.md | Every conversation | Always in context |
Rules (.claude/rules/) |
Every conversation (glob-matched) | Always in context for matching files |
Skills (.claude/skills/) |
On demand (triggered by user or description match) | Only when activated |
Agents (.claude/agents/) |
On demand (when invoked) | Only when activated |
| Context files | When referenced or read | Only when needed |
Step 3: Flag Issues
- Oversized files: Any file over 5,000 tokens (20,000 characters)
- Duplicate content: Content that appears in multiple files (search for repeated paragraphs)
- Always-loaded bloat: Rules or CLAUDE.md sections that could move to on-demand skills
- Unused components: Skills or agents that have no clear trigger or overlap with another
Step 4: Generate Report
Token Budget Overview
| Component | Files | Est. Tokens | Loaded | Notes |
|---|---|---|---|---|
| CLAUDE.md | 1 | [count] | Always | |
| Rules | [n] | [count] | Always (glob) | |
| Skills | [n] | [count] | On demand | |
| Agents | [n] | [count] | On demand | |
| Context | [n] | [count] | On read | |
| Reference | [n] | [count] | On read | |
| Total | [count] |
Always-Loaded Budget

Ranked by impact (tokens saved):

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.

context-budget-analyzer is a skill published in the GitHub repository bjorn-ingmanson/thefroject-plugins (1 stars, last pushed 2mo ago), licensed MIT. It adds 35 tokens to every session and 730 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 2026-08-31.
