Codex Usage API Companion

Act as an evidence-first analyst for Codex Usage Tracker data. Prefer MCP JSON payloads, answer from structured evidence, and keep the user-facing result concise.

Operating Rules

• For "Open dashboard" style requests, start the live localhost dashboard with codex-usage-tracker serve-dashboard --context-api explicit --open. Refresh is the default for dashboard launch commands. Use open-dashboard only when the user explicitly wants a static/offline snapshot or the environment cannot keep a server alive. Say the result is static and Live requires serve-dashboard.
• Refresh with refresh_usage_index unless the user asks for a static historical snapshot.
• Start with aggregate/shareable tools. Do not expose prompts, assistant messages, raw tool output, pasted secrets, raw commands, full paths, or transcript snippets unless the user explicitly asks for local content or raw context.
• Check top-level schema, content_mode, includes_indexed_content, includes_raw_fragments, row counts, truncation, and caveats before interpreting payloads.
• Name scope: time window, project/thread/model filters, included archived state, row limit, detail mode, and whether results are estimates.
• Separate exact facts from estimates. Call out pricing_estimated, missing pricing_model, usage_credit_confidence, missing allowance windows, and outside-usage caveats.
• For broad asks, give diagnosis plus remediation: Evidence, Hypothesis result, Likely waste pattern, Next action, How to verify.

Agentic Investigation Loop

Use this loop for "look through my usage", "make recommendations", "test hypotheses", "what else should I inspect?", and token-waste discovery:

1. Start with usage_suggest_investigations(goal=...) when the user needs ideas, otherwise call usage_investigate(goal=...) directly.
2. Convert findings into explicit hypotheses: I'd like to be able to..., I will accomplish it using..., I'm missing access to..., My hypothesis was true/false/inconclusive because....
3. Drill into recommended tools such as usage_large_low_output_calls, usage_shell_churn, usage_repeated_file_rediscovery, usage_allowance_diagnostics, usage_threads, or usage_calls.
4. Recommend concrete fixes, not just summaries: shorter handoff, split thread, preserved cache context, lower effort on routine tasks, targeted script, repo note, skill update, or an existing tool such as Headroom when available and relevant.
5. End with the verification tool/query the user should run after changing behavior.

For maintainer dogfood or plugin-quality checks, prefer the MCP polling flow when available: call usage_dogfood_start(privacy_mode="strict"), poll usage_dogfood_status(job_id) until completed or failed, then call usage_dogfood_result(job_id). After one fresh run, use usage_dogfood_start(refresh=False, use_cache=True, privacy_mode="strict") for repeated checks on unchanged data and confirm result_cache.hit. Use the blocking CLI fallback only when MCP polling tools are unavailable: codex-usage-tracker dogfood-agentic --privacy-mode strict --json. Treat the output as a compact aggregate QA artifact that must not include raw prompts, raw tool output, full paths, or indexed fragments.

Router

1. If the user asks what to inspect, wants suggestions, or is unsure where to start, call usage_suggest_investigations(goal=...).
2. If the user asks broadly to look through usage, find waste, explain expensive usage, improve efficiency, or recommend changes, call usage_investigate(goal="token_waste") or usage_investigate(goal="overview") first, then drill into its recommended_next_tools.
3. If the user frames the work as hypotheses, asks for true/false/partial decisions, or wants "I'd like to / I will use / I'm missing / hypothesis result" output, call usage_test_hypotheses(question=..., hypotheses=...).
4. If the user asks whether limits/allowance changed, whether they are throttled, why weekly usage moved, or why the 5-hour counter looks weird, call usage_investigate(goal="allowance_change"), then usage_allowance_diagnostics(window_kind="weekly", privacy_mode="strict") when evidence is needed. Use usage_allowance_export(...) for manually shareable evidence.
5. If the user asks about cache misses, cold resumes, context bloat, or low-output expensive calls, call usage_investigate(goal="cache_failure"), then inspect usage_large_low_output_calls(...), usage_calls(...), usage_report_pack(...), or usage_context_bloat_scan(...).
6. If the user asks about repeated shell probing, repeated file rediscovery, or workflow churn, call usage_investigate(goal="workflow_churn"), then inspect usage_shell_churn(...), usage_repeated_file_rediscovery(...), or usage_investigation_walk(question=...).
7. If the user asks a precise dashboard/API question, use the direct tool: usage_calls, usage_call_detail, usage_threads, usage_summary, usage_query, session_usage, usage_report_pack, usage_dashboard_recommendations, usage_recommendations, most_expensive_usage_calls, usage_pricing_coverage, or usage_source_coverage.
8. Use usage_content_search(...) and usage_thread_trace(...) only for explicit local content-index exploration when the user agrees transcript-level indexed snippets are needed.
9. Use usage_call_context(...) only when the user explicitly asks for raw local context and the MCP server has raw context enabled.

Tool Stance

• usage_suggest_investigations is the front door for ideas. It should return a short, goal-led menu with adjacent safe next options.
• usage_investigate is the first stop for broad agentic analysis. The default detail_mode="compact" returns evidence summaries and compact rows; use detail_mode="full" only when full underlying diagnostic rows are necessary.
• usage_test_hypotheses is the first-class hypothesis runner. Use it when the user wants explicit true, false, partially_true, or insufficient_evidence decisions and the "I would like / I will use / I'm missing" framing.
• usage_allowance_diagnostics is the main allowance-change evidence tool. Treat weekly windows as the primary signal and 5-hour windows as noisy rolling-window context.
• usage_large_low_output_calls, usage_shell_churn, and usage_repeated_file_rediscovery are the most actionable token-waste probes. Use them to turn broad findings into concrete next steps.
• usage_investigation_walk can use local content/event-index signals for deeper pattern scans, but it is not the default shareable report.
• If MCP tools are unavailable, use CLI JSON equivalents documented in docs/cli-json-schemas.md.

Remediation Guidance

Recommend fixes only when supported by evidence. Useful categories include:

• Dashboard inspection: open Calls, Threads, Call Investigator, Diagnostics Notebook, or Allowance Intelligence around specific evidence rows.
• Workflow changes: split long threads after planning, preserve handoff summaries, avoid broad rediscovery, lower effort for routine tasks, and narrow test selection before final gates.
• Existing tools: suggest Headroom when context pressure or handoff timing appears relevant and the tool is available.
• Custom local solutions: suggest a small script, command, repo note, or skill update when the same file discovery, shell loop, or validation sequence keeps recurring.

Answer Style

• Lead with the direct answer and strongest metric.
• Use at most one short progress update, such as "Refreshing aggregate usage, then ranking likely waste patterns."
• Keep explanations tied to aggregate fields or clearly labeled local-index evidence.
• Do not guess conversation content from token patterns.
• For allowance-change answers, separate local evidence from public claims, quote the evidence grade, and say when outside usage or missing observations could explain movement.

Codex Usage Tracker

Unofficial project: Codex Usage Tracker is independent and is not made by, affiliated with, endorsed by, sponsored by, or supported by OpenAI. OpenAI and Codex are trademarks of OpenAI.

Use this plugin to inspect aggregate token usage from local Codex session logs.

Privacy Boundary

The index, dashboard payload, CSV export, and normal summaries are aggregate-only. They should never return prompts, assistant message text, tool outputs, pasted secrets, or raw transcript snippets.

The only exception is usage_call_context, which intentionally reads one selected record's source JSONL on demand. It requires CODEX_USAGE_TRACKER_ALLOW_RAW_CONTEXT=1 in the MCP server environment. Use it only when the user explicitly asks to inspect actual context, and mention that returned text is local, redacted, size-limited, and not persisted by the tracker.

Fast Paths

• For "Open dashboard" or similar dashboard-open requests, do not inspect repository files, plugin manifests, tool registries, git status, or local logs first. Start the live localhost dashboard with codex-usage-tracker serve-dashboard --context-api explicit --open so Refresh, Live, load-limit, and history-scope controls can call the local API. Refresh is the default for dashboard launch commands; use --no-refresh only when the user explicitly asks for a cached snapshot. Keep the server running while the user is using the dashboard. Use codex-usage-tracker open-dashboard only when the user explicitly asks for a static/offline snapshot or when the current environment cannot keep a server process running, and say that the result is static and Live requires serve-dashboard.
• For "Heaviest thread?", "Thread leaderboard", or similar thread-ranking requests, do not inspect repository files, SQLite schemas, plugin manifests, process lists, dashboard servers, or local logs manually. Use the tracker API: refresh the aggregate index, then rank threads with usage_summary(group_by="thread", limit=10, response_format="json").
• If MCP tools are unavailable for thread-ranking requests, run codex-usage-tracker refresh --json and codex-usage-tracker summary --group-by thread --limit 10 --json. The summary is already ordered by total_tokens descending.
• Answer thread-ranking requests directly from the summary rows. For the heaviest-thread question, lead with the first row's thread and total tokens; for leaderboard requests, show a compact ranked list.
• If the CLI command is missing for dashboard-open requests and you are already inside the source checkout, use PYTHONPATH=src .venv/bin/python -m codex_usage_tracker.cli serve-dashboard --context-api explicit --open. Use the source-checkout open-dashboard fallback only for static/offline snapshots or when a long-running server cannot be kept alive.
• If the CLI command is missing for thread-ranking requests and you are already inside the source checkout, use PYTHONPATH=src .venv/bin/python -m codex_usage_tracker.cli refresh --json and PYTHONPATH=src .venv/bin/python -m codex_usage_tracker.cli summary --group-by thread --limit 10 --json.
• If neither command is available, say briefly that the tracker CLI is not on PATH and ask the user to run codex-usage-tracker setup or reinstall with pipx.
• Keep dashboard-open narration minimal: one short progress note if needed, then the localhost URL, or if falling back to a static file, the file path plus a note that Live requires serve-dashboard. Do not narrate plugin discovery.

Suggested Usage Questions

When the user wants ideas, suggest concrete aggregate investigations:

• Look through my usage for token waste.
• Find calls where context got bloated.
• Show me where caching failed.
• Which threads are draining the most?
• What changed recently?
• Check whether weekly allowance behavior changed.
• Explain why the 5-hour counter looks noisy.
• Build strict-privacy allowance evidence I can share.
• Find expensive calls worth opening in the investigator.
• Check whether model or effort choice is wasting tokens.
• Test my usage-waste hypotheses and say what was true, false, or inconclusive.
• Compare repeated file rediscovery, shell churn, and large low-output calls.
• Build a strict-privacy summary I can share.

Route these through usage_report_pack, usage_calls, usage_threads, usage_summary, and usage_call_detail before considering raw context.

Remediation Recommendations

When a usage-waste investigation finds clear patterns, do not stop at "interesting." Recommend practical next actions and existing tools that could reduce future usage. Keep recommendations tied to aggregate evidence, and label speculative ideas.

• If context pressure is high, threads are long, or repeated file reads dominate, suggest Headroom if available as a follow-up tool for estimating context/headroom and deciding whether to split the thread, summarize, or start a fresh task.
• If cache ratio is low on repeated work, suggest concrete workflow fixes: keep related work in one thread, avoid unnecessary broad file reads, pin reusable project context in docs, or create a small project command/script that produces the exact aggregate needed.
• If one thread or subagent pattern dominates, suggest narrowing the task, splitting investigation from implementation, or creating a repeatable custom checklist/command so Codex does not rediscover the same facts every turn.
• If effort/model choice looks expensive, compare aggregate results by model and effort before recommending lower effort, smaller models, or explicit "use minimal reasoning unless blocked" instructions.
• If diagnostics point to missing local automation, offer to design a custom lightweight solution: a repo command, lint/test selector, dashboard report preset, support-bundle check, or Codex skill update that prevents the same waste pattern.
• Mention dashboard actions that help the user verify the fix: open Calls filtered to the expensive rows, Threads sorted by tokens, Call Investigator for a selected record, or Diagnostics Notebook for usage-drain evidence.

Phrase the final answer as "what happened, why it likely matters, what to try next, how to verify." Avoid implying an external tool is installed unless the current environment or tool registry confirms it.

Agentic Dogfood

When the maintainer asks whether MCP/skill recommendations are getting more useful, prefer the MCP polling flow when available:

1. Call usage_dogfood_start(privacy_mode="strict").
2. Poll usage_dogfood_status(job_id) until completed or failed.
3. Call usage_dogfood_result(job_id) for the compact aggregate artifact.
4. For repeated checks on unchanged data after one fresh run, call usage_dogfood_start(refresh=False, use_cache=True, privacy_mode="strict") and confirm result_cache.hit.

Use the source checkout or installed CLI only as fallback:

codex-usage-tracker dogfood-agentic --privacy-mode strict --json

Use it to check old and new hypothesis families, direct reports, suggested goals, investigation findings, and privacy checks. Treat it as compact QA evidence, not as a user-facing raw transcript export.

For experiment-style answers, use this structure:

• I'd like to be able to...
• I will accomplish it using...
• I'm missing access to...
• My hypothesis was true/false/inconclusive because...
• Next tool or fix...

Common Workflows

• Refresh the index before answering usage questions.
• Use usage_doctor when setup, plugin discovery, MCP launch, dashboard output, or pricing estimates look wrong.
• Use usage_summary for high-level totals by date, model, effort, cwd, thread, or session.
• Use usage_query for stable JSON rows filtered by date, project, model, effort, thread, pricing status, token minimums, or Codex credit minimums.
• Use usage_status for dashboard/index freshness, active/scoped/total row counts, latest refresh timestamp, and observed allowance windows.
• Use usage_allowance_history normalized observed allowance snapshots when user needs rows behind weekly or 5-hour movement.
• Use usage_allowance_diagnostics for evidence-graded allowance-change questions; weekly is primary, five-hour is noisy rolling-window context.
• Use usage_allowance_export for strict-privacy local allowance evidence bundles intended for manual sharing.
• Use usage_calls for the same aggregate Calls table rows as the React dashboard, including pagination, filters, derived pricing status, and credit confidence.
• Use usage_call_detail for the aggregate Call Investigator payload for one record_id. Use usage_call_context only for explicit raw-context requests.
• Use usage_threads for the same aggregate Threads table rows as the dashboard.
• Use usage_report_pack for dashboard report cards plus compact evidence rows when the user wants less cloudy "what should I inspect?" output.
• Use usage_dashboard_recommendations when the dashboard-specific recommendation payload is more useful than the older markdown-oriented recommendation report.
• Use usage_recommendations when the user asks what to inspect next or wants ranked action items by aggregate severity.
• Use usage_summary presets today, last-7-days, by-model, by-cwd, by-thread, and expensive for common requests.
• Use usage_pricing_coverage when the user asks whether costs are fully priced or which models use estimated or missing pricing.
• Use usage_source_coverage when the user asks whether parser/source provenance coverage is healthy or whether the local index is ready for deeper investigation.
• Use session_usage for per-call and per-turn detail for one session.
• Use usage_call_context for one selected model call when the user asks to load actual logged context on demand.
• Use most_expensive_usage_calls to identify high-token calls and aggregate efficiency signals.
• Use privacy_mode="redacted" or privacy_mode="strict" for MCP tools, or the CLI global option --privacy-mode strict before a subcommand, when the user plans to share dashboards, CSV, JSON, screenshots, or support bundles.
• Use generate_usage_dashboard when the user wants a visual hoverable report, including flat calls, threaded-by-thread views, parent-thread latching for spawned subagents, auto-review attachment details, an active-only default, and explicit all-history archived-session opt-in.
• Use export_usage_csv when the user wants local spreadsheet-friendly data.
• Use update_usage_pricing_config when the user wants cost estimates based on OpenAI-published text-token pricing. This refreshes the local pricing cache and does not send local usage data anywhere. Internal Codex labels may include explicitly marked best-guess estimates when no public pricing row exists.
• Use init_usage_pricing_config only when the user wants a manual local pricing template or override file.
• Codex credit estimates are aggregate-only and use bundled or locally configured Codex rate-card values. Direct model matches are exact; aliases and inferred labels are marked estimated.
• Use init_usage_allowance_config only when the user wants a local allowance template for manually copied 5-hour or weekly remaining usage from Codex Usage or /status.
• Use allowance diagnostics for questions about limit drops, weekly allowance changes, 5-hour counter weirdness, or throttling. Prefer weekly evidence, read the nonparametric-v1 statistical evidence fields, and explain research_readiness.ready_for_public_claim separately from local evidence grades.

• Use usage_recommendations when the user asks what to inspect next or wants ranked action items by aggregate severity.
• Use usage_summary presets today, last-7-days, by-model, by-cwd, by-thread, and expensive for common requests.
• Use usage_pricing_coverage when the user asks whether costs are fully priced or which models use estimated or missing pricing.
• Use usage_source_coverage when the user asks whether parser/source provenance coverage is healthy or whether the local index is ready for deeper investigation.
• Use session_usage for per-call and per-turn detail for one session.
• Use usage_call_context for one selected model call when the user asks to load actual logged context on demand.
• Use most_expensive_usage_calls to identify high-token calls and aggregate efficiency signals.
• Use privacy_mode="redacted" or privacy_mode="strict" for MCP tools, or the CLI global option --privacy-mode strict before a subcommand, when the user plans to share dashboards, CSV, JSON, screenshots, or support bundles.
• Use generate_usage_dashboard when the user wants a visual hoverable report, including flat calls, threaded-by-thread views, parent-thread latching for spawned subagents, auto-review attachment details, an active-only default, and explicit all-history archived-session opt-in.
• Use export_usage_csv when the user wants local spreadsheet-friendly data.
• Use update_usage_pricing_config when the user wants cost estimates based on OpenAI-published text-token pricing. This refreshes the local pricing cache and does not send local usage data anywhere. Internal Codex labels may include explicitly marked best-guess estimates when no public pricing row exists.
• Use init_usage_pricing_config only when the user wants a manual local pricing template or override file.
• Codex credit estimates are aggregate-only and use bundled or locally configured Codex rate-card values. Direct model matches are exact; aliases and inferred labels are marked estimated.
• Use init_usage_allowance_config only when the user wants a local allowance template for manually copied 5-hour or weekly remaining usage from Codex Usage or /status.
• Use allowance diagnostics for questions about limit drops, weekly allowance changes, 5-hour counter weirdness, or throttling. Prefer weekly evidence, read the nonparametric-v1 statistical evidence fields, and explain research_readiness.ready_for_public_claim separately from local evidence grades.
