reconcile

reconcile is a skill for Claude Code from jovesun-lab/arcgram. It costs 115 tokens per session (945 once invoked), scanned A, original, Apache-2.0.

A checker that compares values written in an Arcgram diagram with matching constants in the code. Arcgram is a diagram format for describing an AI agent’s reasoning or a program flow.

In plain words
What is it for?
Use it to check settings such as timing values or quoted strings and report mismatches, missing constants, non-literal values, and ambiguous matches.
Why use it?
It reveals when the diagram’s stated values no longer match the code, or when the expected code constant is missing or unclear.

Token cost

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 A, and why

reconcile 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.

The scan reads SKILL.md. This mod also ships 2 executable files (reconcile-selftest.mjs, reconcile.mjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Reconcile - code<->diagram @spec bijection validator

Two inputs: a diagram + the code it describes. One question: do the diagram's @spec values still equal the same-named code constants? Returns typed findings; marks, never blocks.

Sibling to Checkpoint: Checkpoint checks structure from the diagram alone; Reconcile checks values across diagram + code. Run both -> the diagram is a faithful, current spec.

Input: the @spec line

A node pins values on one line at the top of desc:

@spec hold_ms=800 fade_ms=200      <- Reconcile reads ONLY this line
  • Prefix @spec (ASCII). key=value, key = the code constant name.
  • Match is case/separator-insensitive: hold_ms = HOLD_MS = holdMs = hold-ms.
  • Value: a number (800, 0x320) or a quoted string ("left").
  • Free prose and a ~ tune: <range> line are for humans - never read.

Reconcile reads only the @spec line + named code constants. No geometry, no prose, no program behavior.

Findings

finding severity means
spec-drift defect @spec value != the code constant
spec-no-constant defect no same-named constant in the code
malformed-spec defect @spec line is not key=value
value-uncovered uncovered constant is computed, not a literal - no verdict
ambiguous-constant uncovered two constants normalize to one name
no-spec-lines uncovered nothing pinned - never a false "clean"

Anchored on the @spec line (not the code): drift is caught both ways, but a code constant on no @spec line is normal, not a finding. The extractor is a tolerant, dependency-free scan of const/let/var =, NAME =, NAME:, #define, :=, [modifiers] const|readonly TYPE NAME =, and C#/Unity bare field initializers [attr] public|private|static TYPE NAME = value (ScriptableObject tuning fields, no const/readonly) (JS/TS/Python/C/Go/C#/Java); numbers normalize (800 == 800.0 == 0x320, and a C#/Java numeric suffix is dropped so 0.2f == 0.2, 800L == 800). A Unity bare field is matched only with a field-only marker (an access modifier, [Attribute], or static), so a method-body local (int x = 5;) is never captured.

What ships with it

3 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.

reconcile is a skill published in the GitHub repository jovesun-lab/arcgram (9 stars, last pushed 20d ago), licensed Apache-2.0. It adds 115 tokens to every session and 945 once invoked, about $0.0006 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.
