Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00030 | $0.00545 |
| Opus 5 | $0.00015 | $0.00272 |
| Sonnet 5 | $0.00006 | $0.00109 |
| Haiku 4.5 | $0.00003 | $0.00055 |
Grade A, and why
mcp-geo-long-horizon-summary 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 12d 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
MCP Geo Long Horizon Summary
Use this skill when a user asks for an OpenAI "Long horizon tasks" style summary for MCP Geo work (runtime, tokens, tool calls, patch volume, compactions, etc.).
Inputs
- Codex session logs under
$CODEX_HOME(defaults to~/.codex). - Repo filter (default:
mcp-geo).
Output
- Summary-card SVG image in
docs/reports/. - Markdown report in
docs/reports/that opens with the summary image. - Optional JSON metrics payload for downstream dashboards.
Runbook
- Generate report:
python3 scripts/codex_long_horizon_summary.py \
--repo-filter mcp-geo \
--summary-svg-output docs/reports/mcp_geo_codex_long_horizon_summary_$(date -u +%F).svg \
--summary-title "Codex MCP-Geo Summary" \
--output docs/reports/mcp_geo_codex_long_horizon_summary_$(date -u +%F).md \
--json-output docs/reports/mcp_geo_codex_long_horizon_summary_$(date -u +%F).json
- If needed, point to a non-default Codex home:
python3 scripts/codex_long_horizon_summary.py \
--codex-home /path/to/.codex \
--repo-filter mcp-geo
- Validate that the report includes these headline metrics:
- Active runtime
- Wall-clock span
- Token usage (input/output)
- Cached input reused
- Tool calls (shell + patch calls)
- Patch volume (added lines from
apply_patch) - Peak single-step tokens
- Auto context compactions
Notes
- Sessions are included when
session_meta.payload.cwdcontains the repo filter. - Patch volume is estimated from
apply_patchpayloads and will not include edits made through other methods. - Token totals use the latest
token_count.total_token_usagesnapshot per session. - Graphic output uses deterministic template file
skills/mcp-geo-long-horizon-summary/templates/summary_card.svg.tmplwith slot-based number substitution. - Template is tuned for slide import (
1920x1080, 16:9) and uses PowerPoint-friendly inline text styling (no CSSfontshorthand) to keep text sizing consistent.
What ships with it
2 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.

mcp-geo-long-horizon-summary is a skill published in the GitHub repository chris-page-gov/mcp-geo (3 stars, last pushed 1mo ago), licensed MIT. It adds 30 tokens to every session and 545 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.
