technical-recon

technical-recon is a skill for Claude Code from skyfox675/agents-skills. It costs 211 tokens per session (3,588 once invoked), scanned A, original, MIT.

A read-only investigation process for an already specified software issue. It traces the request through the codebase and produces an implementation approach, effort estimate, risks, and a recommendation about whether to assign the work.

In plain words
What is it for?
Mapping an issue to relevant code, estimating work, identifying affected areas, documenting risks, and deciding whether the issue is ready for implementation.
Why use it?
It reveals technical scope and likely problems before a developer starts coding.

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

technical-recon 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.

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.

Technical Recon: scope, size, and de-risk a groomed issue before dispatch

An issue can be fully groomed and accepted by stakeholders — clear symptom, desired behaviour, acceptance criteria — and still be unsafe to dispatch, because nobody on the dev team has confirmed how it would be built, how big it is, or what it might break. Technical recon closes that gap: a read-only sub-agent traces the ask into the actual codebase and returns an implementation approach, a level-of-effort estimate, the risks, and a dispatch recommendation. The issue moves from "stakeholders want this" to "the dev team knows what this costs and how to build it."

This is not the intake-triage recon in the issue-filing skill (gh-issue-filing / jira-issue-filing). That one runs a cheap model to classify stub issues into ready-to-dispatch / needs-spec-input / blocked by a five-rule decision tree, with a capped blast radius. Technical recon is the opposite end: the issue is already groomed, and the question is the engineering answer — design, cost, risk — which needs a capable model reading real code, not a cheap classifier. The two compose: intake-triage decides an issue is specified; technical recon decides it is buildable and sized.

Compose with the siblings: dispatch the recon agents with the dispatching-subagents skill; read the issue and post findings with the issue-filing skill's anatomy conventions; set the resulting labels/fields with the control-field skill (gh-issue-labels for GitHub, jira-issue-fields for Jira); and when recon clears an issue, the orchestrating-slots loop dispatches the implementation per the issue-locking skill (gh-issue-locking / jira-issue-locking). Recon itself never claims, never writes code, never opens a PR.

Project bindings

Define these in the adopting project's CLAUDE.md; the body refers to them by placeholder.

Binding Meaning Example
<loe-scale> The LoE vocabulary the team estimates in T-shirt XS|S|M|L|XL (below)
<recon-model> Model tier for recon — a capable one, never the cheap tier sonnet (escalate to opus for deep/cross-cutting asks)
<vetted-state> The label/status meaning "dev-vetted, ready to dispatch" ready-to-dispatch
<needs-input-state> "a technical decision must be made before build" needs-spec-input
<blocked-state> "a dependency must land first" blocked
<loe-field> Where the size is recorded a loe:<size> label, or the Jira Story-points / a custom field
<shared-surfaces> Contention-prone files that mark the plumbing lane (see the issue-filing skill) DB schema, API schema, shared types, design tokens, root manifest/lockfile

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.
