context-budget

v0.6.30

Measure a Claude Code session's fixed startup context payload per item, on the consumer's machine at a pinned, version-stamped binary, including per-tool attribution of the built-in tool pools that /context reports only as lump sums, derived live by A/B bare-name-deny differencing with enforced comparability rules (skill-listing signature, one mode, one binary), an SDK-primary exact meter degrading to a version-aware headless /context parser and then to an honest structured error (never a wrong number), and a per-project measure-toggle-remeasure ledger under the plugin data directory recording every lever's real before/after delta. Report-only: prints exact config, applies nothing.

Install context-budget for Claude Code

Installs for the current user
claude plugin marketplace add IchenDEV/agent-plugin-mkt
claude plugin marketplace update agent-plugin-marketplace
claude plugin install context-budget@agent-plugin-marketplace

Paste and run these commands in a terminal with Claude Code. They add and refresh the PluginsMP catalog, then install this plugin.

The installer fetches third-party code from the source repository shown on this page. This directory validates manifest structure and source location, but does not perform a security audit; review the manifest, components, and source before installing.

Get the source manually
git clone https://github.com/melodic-software/claude-code-plugins

Clone the source repository, then follow its setup instructions to add the plugin to a compatible client. The plugin root is plugins/context-budget/.

Included Skills2

auditskills/audit/SKILL.md

Measure a Claude Code session's fixed startup context payload per item, on this machine at a pinned binary, including per-tool attribution of the built-in tool pools that /context reports only as lump sums, derived live by A/B deny differencing, with a per-project before/after ledger for every lever toggled. Reports only measured numbers; ships none. Use when: 'what is eating my context window at startup', 'measure my startup payload', 'which built-in tools cost the most', 'what would denying this tool save', 'context budget audit', 'baseline my context before trimming', 'did that settings change actually save tokens'. Read-only by default: measures and reports, changes no configuration; `fix` as an explicit argument applies one project-scope trim at a time behind the operator's approval.

setupskills/setup/SKILL.md

Verify context-budget's external prerequisites on this machine: `node`, which both the always-on settings-write checkpoint hook and the measurement engine depend on; the Claude Code CLI the engine measures against; and the optional Agent SDK that enables exact mode. Then report the effective settings-write-ask toggle. Use when: 'set up context-budget', 'configure context-budget', 'is context-budget working', 'why did the settings-write ask not prompt', 'why is the audit not exact', or an audit run reported a missing prerequisite. Check-only: verifies, reports, and points at each remediation; installs nothing and there is nothing setup may write here. Re-runnable and safe.
