reconcile-mcp: Instructions file for Codex

AGENTS.md

reconcile-mcp AGENTS.md is an instructions file for Codex, OpenCode from sebastienrousseau/reconcile-mcp. It costs 713 tokens per session, scanned B, a copy of bankstatementparser-mcp AGENTS.md, Apache-2.0.

A repository instruction file that tells coding agents how to change the reconcile-mcp project safely. It defines release, licensing, version, verification, and reconciliation rules.

In plain words
What is it for?
Use it to guide agent-made changes, release preparation, and verification of reconciliation tools.
Why use it?
It reduces accidental breaking changes and inconsistent project metadata when an agent edits several files. It also states checks that must pass before work is considered complete.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md.

This is sebastienrousseau/reconcile-mcp's own configuration. It tells Codex and OpenCode how to work on reconcile-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything reconcile-mcp configures →

What it costs to keep this loaded

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.

Security

Grade B, and why

reconcile-mcp AGENTS.md scanned grade B with 1 finding 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 15d 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.

Strips warnings and disclaimersmediumAnti-refusal

Omitting safety caveats hides risk from the user and is a common jailbreak preamble.

2. Ensure linter and formatter pass without warnings or new suppressions.

The opening of the file, as written. The whole thing — 49 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

Invariants for AI-assisted contributions to reconcile-mcp. Read this before changing anything.

Everything here applies equally to humans and automated agents. It is addressed to agents because agents can make breaking changes across multiple files before anyone notices.

1. Core Invariants

  1. Strict SemVer sequencing policy: Public releases stay on the 0.0.x line and increment strictly by 0.0.1. Never manually edit version numbers outside the active release branch feat/v<next-version>. v0.1.0 is forbidden until v0.0.999 exists.
  2. Single Active Release PR Invariant: Across all repositories, there MUST be at most ONE active pull request targeting main, which MUST be the release iteration branch feat/v<next-version>.
  3. Dual licensing: The repository is dual-licensed under Apache-2.0 OR MIT. All files must declare an SPDX license header.
  4. Single source of truth: The version in pyproject.toml is the single source of truth. It must agree with __version__, glama.json, server.json, CITATION.cff, and CHANGELOG.md (verified by scripts/verify_versions.py).
  5. Deterministic explainable matching: All core reconciliation tools (reconcile, explain_match, normalize_pain001, normalize_camt053, list_sandbox_scenarios, load_sandbox_scenario, run_sandbox_scenario, match_names_probabilistic, match_amounts_with_fx_drift, reconcile_many_to_many) must remain side-effect-free, read-only, and idempotent.

2. Before You Claim To Be Done (Verification Gates)

Before concluding any task or preparing a commit, run:

make check

Or run the individual gates:

pytest --cov=reconcile_mcp --cov-branch --cov-report=term-missing --cov-fail-under=100
ruff check .
black --check .
mypy reconcile_mcp
python3 scripts/verify_versions.py

All unit tests and conformance tests must pass with 0 failures, 0 warnings, and 100% line and branch coverage.

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.
