What is sync-context?

A documentation-maintenance tool that finds outdated or mismatched information in a project's AI guidance files. These files include AGENTS.md, CLAUDE.md, and documents under docs/ai/.

Use it to detect documentation drift and propose small updates after code changes or when session-start warnings report stale information.

It helps keep agent instructions aligned with the code and documentation without silently rewriting the project's guidance.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00045	$0.00601
Opus 5.5	$0.00018	$0.00240
Sonnet 5.5	$0.00009	$0.00120
Haiku 4.5	$0.00005	$0.00060

Security

Grade A, and why

sync-context 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 2mo 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.

How it starts

The opening of the file, as written. The whole thing — 78 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Context Sync

Detect and fix documentation drift across the repo's AI context layer.

Examples

/sync-context — scan all mappings and propose updates
/sync-context pybondlab — scan only PyBondLab-related mappings

Hard Rules

NEVER auto-commit doc updates. Always show the proposed edit and wait for approval.
NEVER rewrite entire documents. Propose targeted, minimal edits only.
Preserve the voice and judgment in existing docs — update facts, not opinions.
If a doc references a file that no longer exists, flag it but do not remove without asking.
Do not add new sections or restructure documents unless the drift requires it.

Workflow

1. Run Drift Detection

"<PYTHON>" tools/context_drift.py --json

Parse the JSON output. Each entry has: source (glob), doc (file path), days_stale (float).

If $ARGUMENTS contains a keyword (e.g., pybondlab), filter to entries where either source or doc contains that keyword. Otherwise process all entries.

2. For Each Stale Mapping

For each drift warning, in order:

Read the current doc using the Read tool.
Identify what changed in the source since the doc was last updated:
```
git log --oneline --since="<days_stale> days ago" -- <source_files>
```
Then read the relevant source files to understand the current state.
Compare what the doc says against the current source state. Identify specific lines in the doc that are now inaccurate, incomplete, or misleading.
Propose a targeted edit — show the old text and the proposed replacement. Use the Edit tool format (old_string → new_string). Explain the reason for each change in one sentence.
Wait for user approval before applying each edit.

3. Summary

After processing all mappings, print a summary table:

| Doc                    | Status   | Action                                    |
|------------------------|----------|-------------------------------------------|
| docs/ai/onboarding.md  | Updated  | bootstrap.py uv changes reflected         |
| docs/ai/pybondlab.md   | Current  | no drift detected                         |
| AGENTS.md              | Skipped  | user declined update                      |

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.

sync-context is a skill published in the GitHub repository Alexander-M-Dickerson/ai-asset-pricing (59 stars, last pushed 6mo ago), licensed MIT. It adds 45 tokens to every session and 601 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-30.
